ORA-00020: maximum number of processes (n) exceeded in ASM Instance

Thu, 2011-08-04 08:02

Increase the PROCESSES parameter in the ASM parameter file

Processes = 25 + 15 * n, where n is the number of instances on the box using ASM for their storage.

NOTE : this formula is for a basic instance and does not accomodate for

* Multiple ARCH processes
* Multiple LGWR processes

Should the ORA-0020 occur even after implementing this formula ... add additional for any multiples of these background processes

Refer NOTE 265633.1 "ASM Technical Best Practices" for more information.

Objects Remain In Their Original Tablespaces After Run Oatm

Wed, 2008-03-26 04:51
Migrated to the new tablespaces using OATM but there are objects left behind in original tablespaces. There were no errors reported during tablespace migration.

SQL> select tablespace_name, count(1) from dba_Segments group by tablespace_name;
------------------------------ ----------

SQL> select segment_name, segment_type from dba_segments
2* where tablespace_name='APPLSYSD'
---------- ------------------


One of the circumstances under which a 'SPACE HEADER' segment gets created is if a 'dictionary managed' tablespace is migrated to 'locally managed' (see dbms_space_admin.tablespace_migrate_to_local()).

The space header segment contains the extent bitmap and is allocated during the migration of the tablespace. Since there is no reserved space after the file header (as with locally managed tablespaces) the bitmap segment will be allocated somewhere in the "data" area of the datafile. During its creation the segment will pick up some of the storage attributes (e.g. MAXEXTENTS) from the default storage clause of the tablespace. Once the segment has been created it can neither be dropped nor changed.


You can ignore these "left-over" objects. Please go ahead and drop old tablespaces

How to Purge the RECYCLEBIN in Oracle 10g

Tue, 2008-03-25 21:49

The Recycle Bin is a virtual container where all dropped objects reside. Underneath the covers, the objects are occupying the same space as when they were created. If table EMP was created in the USERS tablespace, the dropped table EMP remains in the USERS tablespace. Dropped tables and any associated objects such as indexes, constraints, nested tables, and other dependant objects are not moved, they are simply renamed with a prefix of BIN$$. You can continue to access the data in a
dropped table or even use Flashback Query against it. Each user has the same rights and privileges on Recycle Bin objects before it was dropped. You can view your dropped tables by querying the new RECYCLEBIN view. Objects in the Recycle Bin will remain in the database until the owner of the dropped objects decides to permanently remove them using the new PURGE command. The Recycle Bin objects are counted against a user's quota. But Flashback Drop is a non-intrusive feature. Objects in the Recycle Bin will be automatically purged by the space reclamation process if

o A user creates a new table or adds data that causes their quota to be exceeded.
o The tablespace needs to extend its file size to accommodate create/insert operations.

There is no issues with DROPping the table, behaviour wise. It is the same as in 8i / 9i. The space is not released immediately and is accounted for within the same tablespace / schema after the drop.

When we drop a tablespace or a user there is NO recycling of the objects.

o Recyclebin does not work for SYS objects

Checking the RECYCLEBIN Objects

SELECT object_name,original_name,operation,type,dropscn,droptime FROM user_recyclebin;

SELECT owner,original_name,operation,type FROM dba_recyclebin;

Purging the Recyclebin

Subject: 10g Recyclebin Features And How To Disable it( _recyclebin )
Doc ID: Note:265253.1 Type: BULLETIN

Applies to: Oracle Server - Enterprise Edition - Version: to
Information in this document applies to any platform.
Purpose:- This bulletin illustrates the new recyclebin functionality provided with the 10g database

Scope and ApplicationCan be used by Oracle Support Analyst and DBA

10g Recyclebin Features And How To Disable it( _recyclebin )ABOUT 10g RECYCLEBIN
In order to have FLASHBACK DROP functionality a recyclebin is provided to every oracle user.

SQL> desc recyclebin
Name Null? Type
----------------------------------------- -------- ------------

The recyclebin is a public synonym and it is based on the view user_recyclebin which in turn is based on sys.recyclebin$ table.

Related recyclebin objects:

SQL> SELECT SUBSTR(object_name,1,50),object_type,owner
FROM dba_objects
WHERE object_name LIKE '%RECYCLEBIN%';
--------------------------- ------------------- ----------

9 rows selected.

SQL> SELECT * FROM v$version;
Oracle Database 10g Enterprise Edition Release - 64bi

TNS for Solaris: Version - Production
NLSRTL Version - Production

SQL> sho user
USER is "BH"

SQL> SELECT object_name,original_name,operation,type,dropscn,droptime
2 FROM user_recyclebin

no rows selected

Table created.

Table dropped.

SQL> SELECT object_name,original_name,operation,type,dropscn,droptime
2 FROM user_recyclebin
3 /
------------------------------ -------------------------------- --------- ------------------------- ---------- -------------------
BIN$1Unhj5+DSHDgNAgAIKds8A==$0 T1 DROP TABLE 8.1832E+12 2004-03-10:11:03:49

SQL> sho user

SQL> SELECT owner,original_name,operation,type
2 FROM dba_recyclebin
3 /

------------------------------ -------------------------------- --------- ------

We can also create a new table with the same name at this point.

@Pre-, the recycled objects can also be viewed in user_tables and dba_tables
@Fix for Bug 3255906 changed this behaviour to maintain compatibility with 9i


In order to completely remove the table from the DB and to release the space the new PURGE command is used.

From BH user:
Table purged.


SQL> PURGE TABLE "BIN$1UtrT/b1ScbgNAgAIKds8A==$0";
Table purged.

From SYSDBA user:
SQL> SELECT owner,original_name,operation,type
2 FROM dba_recyclebin
3 /
no rows selected

From BH user:
SQL> SHOW recyclebin

There are various ways to PURGE objects:

PURGE recyclebin; (Purge all objects in Recyclebin)
PURGE dba_recyclebin; (Purge all objects / only SYSDBA can)
PURGE TABLESPACE users; (Purge all objects of the tablespace)
PURGE TABLESPACE users USER bh; (Purge all objects of the tablspace belonging to BH)

For an object, the owner or a user with SYSDBA privilege or a user with DROP ANY... system privilege for the type of object to be purged can PURGE it.


We can DROP and PURGE a table with a single command

From BH user:
Table dropped.

2 FROM recyclebin
3 /
no rows selected

There is no need to PURGE.

On 10gR1, in case we want to disable the behavior of recycling, there is an underscore parameter
"_recyclebin" which defaults to TRUE. We can disable recyclebin by setting it to FALSE.

From SYSDBA user:
SQL> SELECT a.ksppinm, b.ksppstvl, b.ksppstdf
FROM x$ksppi a, x$ksppcv b
WHERE a.indx = b.indx
AND a.ksppinm like '%recycle%'
ORDER BY a.ksppinm
Parameter Value Default?
---------------------------- ---------------------------------------- --------
_recyclebin TRUE TRUE

From BH user:
Table created.

Table dropped.

SQL> SELECT original_name
FROM user_recyclebin;

From SYSDBA user:
System altered.

SQL> SELECT a.ksppinm, b.ksppstvl, b.ksppstdf
FROM x$ksppi a, x$ksppcv b
WHERE a.indx = b.indx
AND a.ksppinm like '%recycle%'
ORDER BY a.ksppinm
Parameter Value Default?
---------------------------- ---------------------------------------- --------
_recyclebin FALSE TRUE

From BH user:
Table created.

Table dropped.

SQL> SELECT original_name
FROM user_recyclebin;
no rows selected

There is no need to PURGE.

As with anyother underscore parameter, setting this parameter is not recommended unless
advised by oracle support services.

On 10gR2 recyclebin is a initialization parameter and bydefault its ON.
We can disable recyclebin by using the following commands:


The dropped objects, when recyclebin was ON will remain in the recyclebin even if we set the recyclebin parameter to OFF.

Estimating the Network Band Width Required for Standby Database

Wed, 2008-01-30 00:15
For Better DR (Disaster Recovery) Site setup it is important to know the required Bandwidth Link Between the Primary and DR Site.

By using the Below formula, we can estimate the required Bandwidth Based on the Peak redo rate.

Required bandwidth = ((Redo rate in bytes per second / 0.7) * 8) / 1,000,000

= bandwidth in Mbps.

How to find a Redo Rate for a Database:-

Redo Rate can be found out from the Statspack report. During the peak duration of your business, run a Statspack snapshot at periodic intervals. For example, you may run it three times during your peak hours, each time for a five-minute duration. The Statspack snapshot report will include a "Redo size" line under the "Load Profile" section near the beginning of the report. This line includes the "Per Second" and "Per Transaction" measurements for the redo size in bytes during the snapshot interval. Make a note of the "Per Second" value. Take the highest "Redo size" "Per Second" value of these three snapshots, and that is your peak redo generation rate. For example, this highest "Per Second" value may be 394,253 bytes or 385 KB.

Req'd Bandwidth = ((394253 / 0.7) * 8) / 1,000,000
= 4.5 Mbps

How to Import the PUTTY Settings from One Machine to Another Machine

Mon, 2007-11-26 00:15
Most of the DBA's work 24 x 7 and finds difficiult and time consuming to configure the Whole List of Server settings in PUTTY. I had gone through Google hits and found one workaround to import your putty settings .

Work Around

1. Run the command --> regedit /e "%userprofile%\desktop\putty.reg" HKEY_CURRENT_USER\Software\SimonTatham at the command prompt.

2. Copy the Putty.exe and putty.reg onto Target Machine.

3. Right Click the putty.reg and click the option "Merge", this will import the settings to the target registry, and after that you can see all the server details which were defined by you earlier in Source Machine.

Note:- SimonTatham is the person behind the PUTTY Software.

Upgrading the Recovery Catalog Database from 9i to 10g

Mon, 2007-11-19 19:18
The Rman Catalog Upgarde is same as normal Database upgrade and can be accomplished in two ways.

a) Updrade the Database from 9i to 10g
- Connect to rman catalog datase.
- Issue the rman command "upgrade catalog" as this upgrades the catalog database from 09.02.00 to

b) Fresh Install of 10g Database / Use the existing 10g Database.
- Create the rman user and grant create session, recovery_catalog_owner, create type to rman user.
- Export import of Rman Schema
- Issue the rman Command :upgrade catalog"

Note:- You will encounter the below warning or error message , if you have not upgraded the catalog after the database version upgrade.
connected to target database: DSSPROD (DBID=1021024992)
connected to recovery catalog database
PL/SQL package RMAN.DBMS_RCVCAT version 09.02.00 in RCVCAT database is too old

1. Connect to recovery catalog database as rman user.
2. issue the rman command " upgrade catalog" twice

Sizing the UNDO TABLESPACE for Automatic Undo management

Thu, 2007-11-15 21:43
Sizing an UNDO tablespace requires three pieces of data.

- (UR) UNDO_RETENTION in seconds
- (UPS) Number of undo data blocks generated per second
- (DBS) Overhead varies based on extent and file size (db_block_size)

UndoSpace = [UR * (UPS * DBS)] + (DBS * 24)

Two can be obtained from the initialization file: UNDO_RETENTION and DB_BLOCK_SIZE.
The third piece of the formula requires a query against the database. The number of undo blocks generated per second can be acquired from V$UNDOSTAT.

The following formula calculates the total number of blocks generated and divides it by the amount of time monitored, in seconds:

SQL>SELECT (SUM(undoblks))/ SUM ((end_time - begin_time) * 86400) FROM v$undostat;

Column END_TIME and BEGIN_TIME are DATE data types. When DATE data types are subtracted, the result is in days. To convert days to seconds, you multiply by 86400, the number of seconds in a day.

The result of the query returns the number of undo blocks per second. This value needs to be multiplied by the size of an undo block, which is the same size as the database block defined in DB_BLOCK_SIZE.

The following query calculates the number of bytes needed:

SQL> SELECT (UR * (UPS * DBS)) + (DBS * 24) AS "Bytes"
FROM (SELECT value AS UR FROM v$parameter WHERE name = 'undo_retention'),
(SELECT (SUM(undoblks)/SUM(((end_time - begin_time)*86400))) AS UPS FROM
v$undostat), (select block_size as DBS from dba_tablespaces where
tablespace_name= (select value from v$parameter where name
= 'undo_tablespace'));

Enabling , Disabling , Change the password protection on the RDBMS and Tools (8.0.6) listeners in an Oracle Applications 11.5.x

Thu, 2007-11-15 01:38
The steps in this guide should be performed after applying the following AutoConfig patches:-

3453499 (11i.ADX.F)
5225940 (Post ADX.F Fixes)

How to enable/disable/change the password

To enable/disable or change the password script must be used.

DB Tier: $ORACLE_HOME/appsutil/bin/
Apps Tier: $AD_TOP/bin/

This has the following syntax:-

Valid arguments for
help : get usage information
contextfile : provide Applications or DB Tier context file name

Set the Applications (APPSORA.env) or RBDMS ($CONTEXT_NAME.env)
Run one of the following commands

Example 1: To enable listener password contextfile=$CONTEXT_FILE enablepassword

Example 2: To disable listener password contextfile=$CONTEXT_FILE disablepassword

Example 3: To change existing listener password contextfile=$CONTEXT_FILE changepassword

Further information:
This will change the contextfile variable s_enable_listener_password to "ON" or "OFF"
Update/Remove the listener.ora with a PASSWORDS_PROD entry and the encypted password value


If the listener is not running it will not start it.
If the listener is currently running it will stop and restart it.
Controlling a password protected listener .Once the password is enabled the following methods can now be used to stop/start the listener:-

Apps Tier:

Use script $COMMON_TOP/admin/scripts/$CONTEXT_NAME/

$COMMON_TOP/admin/scripts/$CONTEXT_NAME/ start
$COMMON_TOP/admin/scripts/$CONTEXT_NAME/ stop

This script will check the listener.ora for the encypted password, and use this to stop/start the listener.

DB Tier:

Method A: Use script $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/


$ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/ start PROD
$ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME/ stop PROD

This script will check the listener.ora for the encypted password, and use this to stop/start the listener.

Method B : Use command line options in the Listener Control Utility LSNRCTL
Start the Listener Control Utility

$ lsnrctl

Enter the listener name
LSNRCTL > set current_listener PROD

Enter password for the Listener
LSNRCTL > set password or


LSNRCTL > set password 654FA907952B15B


LSNRCTL > set password
Password: apps

To determine the Status of the listener:
LSNRCTL > status

To Stop the listener:
LSNRCTL > stop

To start the listener:
LSNRCTL > start

To exit :
LSNRCTL > start

Changing DB 32-Bit to 64-Bit

Tue, 2007-11-06 02:56

1. Ensure that there is ample free size for the 64bit release installation.
Recommended free space should be 3G.

2. Start the Installer GUI.

3. On the File Locations Screen, create a new name and path for the 64bit
oracle installation under the Destination.

A typical entry would be

Name: orahome920_64b
Path: /u01/app/oracle/product/9.2.0-64b

4. Proceed with the installation. Stop at the configuration assistant
configuration screen.

5. Install the latest 64bit patch set under the new oracle installation.


The instructions in this section guide you through changing the word-size of
your current release (switching from 32-bit software to 64-bit software or vice versa).

Complete the following steps to change the word-size of your current release:

1. Start SQL*Plus.

2. Connect to the database instance AS SYSDBA.

3. Run SHUTDOWN IMMEDIATE on the database:

4. Perform a full offline backup of the data depending on the available backup
mechanism, eg BCV, Unix file copy.

5. If the initialization parameter file eg initSID.ora, spfileSID.ora, listener.ora, sqlnet.ora resides within the old OR
ACLE_HOME, then copy it to the corresponding location of the new 64b it ORACLE_HOME. If the parameter files are symbol
ic links to another location, then the symbolic links have to be created in the new ORACLE_HOME.

The same links have to be created in new $ORACLE_HOME/dbs.

6. Change your active Oracle instance environment to point at the new 64Bit ORACLE_HOME.
Edit /var/opt/oracle/oratab if using dbhome/oraenv to set the environment.


i) set it to the new 64bit Oracle Home path


Change the essential environment setting eg $ORACLE_HOME,$LD_LIBRARY_PATH to use new 64bit Oracle Home Path if h

export ORACLE_HOME=/u01/app/oracle/product/9.2.0

Change to

export ORACLE_HOME=/u01/app/oracle/product/9.2.0-64b

7. Set AQ_TM_PROCESSES=0 if it is not.

a) If using initSID.ora to start instance, then add it to the init file.

b) If using spfileSID.ora to start instance,then the database can be startup and the parameter set by running th
e below command.


c) shutdown the database again.
9. Set _system_trig_enabled = false.

a) If using initSID.ora to start instance, then add it to the init file.
b) If using spfileSID.ora to start instance, then the database can be startup and the parameter set by running th
e below command.


c) shutdown the database again.

The parameter should be set to FALSE for scripts that perform dictionary operations as the objects on which the triggers d
epend may become invalid or be dropped, causing the triggers to fail and thus preventing the scripts from running successf

10. When migrating from a 32-bit Oracle version to a 64-bit Oracle version, Oracle recommends doubling the size of paramet
ers such as:


11. At a system prompt, change to the new 64bit ORACLE_HOME/rdbms/admin

12. Start SQL*Plus.

13. Connect to the database instance AS SYSDBA.



15. Run the following script:

SQL> @?/rdbms/admin/catalog.sql

16. Check for DBMS_PACKAGE validity.

17. If invalid, run below

SQL> alter package dbms_standard compile;
18. Run the following script:

SQL> @?/rdbms/admin/catproc.sql

19. Set the system to spool results to a log file for later verification of

SQL> SPOOL /tmp/catoutw.log

20. Run utlirp.sql:

SQL> @?/rdbms/admin/utlirp.sql

The utlirp.sql script recompiles existing PL/SQL modules in the format required by the new database. This script first
alters certain dictionary tables. Then, it reloads package STANDARD and DBMS_STANDARD, which are necessary for using P
L/SQL. Finally, it triggers a recompile of all PL/SQL modules, such as packages, procedures, types, and so on.

21. Turn off the spooling of script results to the log file:


Then, check the spool file and verify that the packages and procedures compiled successfully. You named the spool fil
e in Step 12; the suggested name was catoutw.log. Correct any problems you find in this file.



23. Remove the parameter aq_tm_processes or set value back to the original value.

a) If using initSID.ora to start instance, then remove or edit it from the init file after shutting down the data

b) If using spfileSID.ora to start instance, then the parameter can be change by running the below command.


To remove the parameter.

24. Remove the parameter _system_trig_enabled = FALSE

a) If using initSID.ora to start instance, then remove it from the init file after shutting down the database.

b) If using spfileSID.ora to start instance, then the parameter can be removed by running the below command.

SQL> ALTER SYSTEM RESET "_system_trig_enabled" SCOPE=SPFILE SID=.*.;

25. The word-size of your database is changed. The database can be shutdown and reopen for normal use.

8) Restart Forms server and Web listeners.

b. Apply the Patch 4261542.

Installation instructions for Apps customers

[Part 1] Shut down the listeners and copy the patch files

1. Stop your web listeners and Forms Server.

2. Make a patch directory within your 6i ORACLE_HOME and unzip this file
within it to create a new subdirectory. You will be able to see the
folder 4261542 which contains the actual one-off files.


[Part 2] Unzip the java class files and regenerate your JAR files

3.Backup the Forms class files, i.e.$ORACLE_HOME/forms60/java/oracle/forms/handler/AlertDialog.class
%cp -r $ORACLE_HOME/forms60/java/oracle/forms/handler/AlertDialog.class
%cp -r $ORACLE_HOME/forms60/java/oracle/forms/engine/Main.class

4. Inside folder 4261542 in step-2 has class files in oracle\forms\engine directory.
Copy this file into ORACLE_HOME/forms60/java/oracle/forms/engine
%cd $ORACLE_HOME/4261542/oracle/forms/engine
%cp Main.class $ORACLE_HOME/forms60/java/oracle/forms/engine/Main.class
%cd $ORACLE_HOME/4261542/oracle/forms/handler
%cp AlertDialog.class $ORACLE_HOME/forms60/java/oracle/forms/handler/AlertDialog.class

5. Make sure that you have set up custom certificates for JAR file signing.
Run adadmin administration utility. Select the "Maintain Files" option
and then the "Generate JAR Files" sub-option.

6. Spot check that the JAR files have been generated by verifying the timestamp.

[Part 3] Restart the listeners

7. Restart the Forms Server.

8. Restart the web listener serving Forms Applets (e.g. Apache or WebDB 2.2).

c. Apply the Patch 5216496.

- Not Availbale for HP TRU64.


STEPS Involved in patching

1. Install the Developer 6i Patch

2. Install the Additional Developer 6i Patches

3. Relink Applications Executables on UNIX Platforms

You can relink these executables by running adadmin
When the Main Menu appears select 'Maintain Applications Files Menu' and then select 'Relink Applications Program'
Answer the questions below as follows, in order to select the individual executables for relinking.

Enter list of products to link ('all' for all products)[all] : fnd
Generate specific executables for each selected product [No] ? y
Relink with debug information [No] ? n

(You will then be offered a list of executables that are available for relinking)

Enter executables to relink, or enter 'all' [all] : f60webmx ar60run ar60runb ar60rund *

* In a multi-node configuration, not all these executables exist on each node. The list of executables will show those that do exist on the node you are currently running on, and only those should be entered to avoid errors.

Refer to the Maintaining Oracle Applications manual for more information on how to use the AD Administration Utility or AD Relink Utility for relinking executables.

4. Apply the Oracle Applications 11i Interoperability Patch

5. Verify your upgrade

Verify that the fndforms.jar and fndewt.jar JAR files have been rebuilt by checking the timestamp for both files in the $OA_JAVA/oracle/apps/fnd/jar directory. If the timestamp is not current and the previous steps completed successfully, run the AD Administration Utility (adadmin), select Maintain Applications Files, then select Generate Product JAR Files. Do not force the regeneration of all JAR files. Again, verify that the fndforms.jar and fndewt.jar JAR files have been rebuilt by checking their timestamps again.
If your JAR files are still not updated, verify all the prior steps, and the Known Issues section below.
If you have applied Developer 6i Patch 6 or above, verify that the PL/SQL version installed is You can run '$ORACLE_HOME/bin/f60gen help=y' to display various component versions. (If the version shown is still please refer to Metalink Note 191573.1 )
For Microsoft Windows platforms, look under Control Panel - Services to see if additional Forms and Reports services were added. If so, disable the new ones by pressing the Startup button, and setting the Startup Type toDisabled.

6. Start the Forms, Reports, HTTP, Concurrent Manager Servers

a. Stop the Forms Server process.

b. Add the following environment variable to the 'Oracle Forms 6.0 environment variables' section of
your '$APPL_TOP/< SID >.env' file as;


c. Source the environment, then restart the Forms Server process

Oracle APPS DBA Interview Questions

Thu, 2007-08-02 01:34
Q1. What is file used for? What's full path of this file? What's significance of this file ?

Ans: The is used by mod_plsql component of Apache to connect to
database. The File is located at $IAS_ORACLE_HOME/Apache/modplsql/cfg .

Q2. Where would i find .rf9 file, and what execatly it does ?

Ans: These files are used during restart of patch in case of patch failure because of some reason.

Q3. Where is appsweb.cfg or appsweb_$CONTEXT.cfg stored & why its used?

Ans: This file is defined by environment variable FORMS60_WEB_CONFIG_FILE This is usually in directory $OA_HTML/bin on forms tier. This file is used by any forms client session. When a user try to access forms , f60webmx picks up this file and based on this configuration file creates a forms session to user/client.

Q4. Can you clone from multi node system to single node system & vice versa ?

Ans: Yes.

Q5. What is .dbc file , there are lot of dbc file under $FND_SECURE, How its determined that which dbc file to use from $FND_SECURE ?

Ans: dbc as name says is database connect descriptor file which stores database connection information used by application tier to connect to database. This file is in directory $FND_TOP/secure also called as FND_SECURE

Q6. Whats things you do to reduce patch timing ?

Ans: # Merging patches via admrgpch
# Use various adpatch options like nocompiledb or nocompilejsp
# Use defaults file
# Staged APPL_TOP during upgrades
# Increase batch size (Might result into negative )

Q7. Can you apply patch without putting Applications 11i in Maintenance mode ?

Ans: Yes, use options=hotpatch as mentioned above with adpatch. from AD.I onwards we need to enable maintenance mode inorder to apply apps patches.

Q8. adident utility is used for what ?

Ans: adident utility in oracle apps is used to find version of any file . AD Identification.
for ex. "adident Header

Q9. How can you licence a product after installation ?

Ans: By using ad utility adlicmgr to licence product in Oracle Apps.

Q10. What is MRC ? What you do to enable MRC in Apps ?

Ans: MRC also called as Multiple Reporting Currency in oracle Apps. Default you have currency in US Dollars but if your organization operating books are in other currency then you as apps dba need to enable MRC in Apps.

Q11. What is access_log in apache , what entries are recored in access_log ? Where is default location of this file ?

Ans: access_log in Oracle Application Server records all users accessing oracle applications 11i. This file location is defined in httpd.conf with default location at $IAS_ORACLE_HOME/Apache/Apache/logs. Entries in this file is defined by directive LogFormat in httpd.conf Typical entry in access_log is - - [10/Sep/2006:18:37:17 +0100] "POST /OA_HTML/OA.jsp?.... HTTP/1.1" 200 28035
where 200 is HTTP status code & last digits 28035 is bytes dowloaded as this page(Size of page).

Q12. What is session time out parameter & where all you define these values ?

Ans: In order to answer first you have to understand what kind of seesions are in Apps 11i and what is Idle timeout ?
In Apps there are two broad categories of session
- Self Service Application Session ( Server by Web Server iAS Apache & Jserv, like iRecruitment, iProcurement)
-Forms session ( served by your form session, like system Administrator)

What is Session Idle time ?
If Oracle Apps client is not doing any activity for some time (when application user goes for coffee or talks over phone) session during that time is called as Idle Session & because of security reason, performance issues and to free up system resource Oracle Applications terminates client session( both forms & self service) after idle time value is reached to the one mentioned in configuration file.

From FND.G or 11.5.9 or with introduction of AppsLocalLogin.jsp to enter into application, profile option "ICX Session Timeout" is used only to determine Forms Session Idle timeout value . This might be confusing as earlier this profile option used to control forms as well as self service application(with session.timeout) session.timeout is used to control Idle session timeout for Self Service Applications ( Served by Jserv via JVM )

From where ICX : Session Timeout & session.timeout get values ?

Autoconfig determines value for profile option "ICX: Session Timeout" and "session.timeout" from entry in context file ( $APPL_TOP/admin/SID_hostname.xml ) with parameter s_sesstimeout where value mentioned is in milliseconds so profile option ICX: Session Timeout value should be s_sesstimeout/ (1000 * 60) which means here its 10 Minutes. This value is also set in in $IAS_ORACLE_HOME/Apache/Jserv where number mentioned is in milli second i.e. 600000 ( equal to 10 Minutes)session.timeout = 600000

session.timeout mentioned in is in milli secondsICX Session Time out mentioned in profile option ICX: Session Timeout is in minutes so ICX session timeout=30 & session.timeout= 1800,000 are same 30 minutes

P.S. ICX Session time out was introduced in FND.D so if your FND version is below D you might not see this variable.

Important Things Apps DBA should consider while setting session timeout value ?
1.. If you keep session.timeout value too high , when some oracle application user accessing Self service application terminates
his session, so longer idle session will drain JVM resource & can result in Java.Lang No Memory available issues .
2. If you keep it too low, users going out for tea or sitting idle for some time have to login again into application & can be
annoying .

Thumb rule is session time out usually set to 30 minutes.

Q13. Where is applications start/stop scripts stored ?

Ans: $COMMON_TOP/admin/scripts/$CONTEXT_NAME

Q14. What are main configuration files in Web Server (Apache) ?

Ans: Main configuration files in Oracle Apps Web Server are

# httpd.conf, apps.conf, oracle_apache.conf, httpd_pls.conf
# jserv.conf, ssp_init.txt,,
# plsql.conf,, plsql.conf

Q15. How to check if Apps 11i System is Autoconfig enabled ?

Ans: Under $AD_TOP/bin check for file & if this exists use contextfile= show=enabled

If this file is not there , look for any configuration file under APPL_TOP if system is Autoconfig enabled then you will see entry like
# AutoConfig automatically generates this file. It will be read and .......

Q16. How to check if Oracle Apps 11i System is Rapid Clone enabled ?

Ans: For syetem to be Rapid Clone enabled , it should be Autoconfig enabled (Check above How to confirm if Apps 11i is Autoconfig enabled). You should have Rapid Clone Patches applied , Rapid Clone is part of Rapid Install Product whose Family Pack Name is ADX. By default all Apps 11i Instances 11.5.9 and above are Autoconfig & Rapid Clone enabled.

Q17. What is plssql/database cache?

Ans: In order to improve performance mod_pls (Apache component) caches some database content to file. This database/plssql cache is usually of type session & plsql cache
# session cache is used to store session information.
# plsql cache is used to store plsql cache i.e. used by mod_pls

Q18. How to determine Oracle Apps 11i Version ?

Ans: select RELEASE_NAME from fnd_product_groups;

You should see output like
11.5.9 or

Q19. What is RRA/FNDFS ?

Ans: Report Review Agent(RRA) also referred by executable FNDFS is default text viewer in Oracle Applications 11i for viewing output files & log files. As most of apps dba's are not clear about Report Server & RRA.

Q20. What is PCP in Oracle Applications 11i ? In what scenarios PCP is Used ?

Ans: PCP stands for parallel Concurrent processing.Usually you have one Concurrent Manager executing your requests but if you can configure Concurrent Manager running on two machines (Yes you need to do some additional steps in order to configure Parallel Concurrent Processing) . So for some of your requests primary CM Node is on machine1 and secondary CM node on machine2 and for some requests primary CM is on machine2 & secondary CM on machine1.

Well If you are running GL Month end reports or taxation reports annually these reposrts might take couple of days. Some of these requests are very resource intensive so you can have one node running long running , resource intensive requests while other processing your day to day short running requets.
another scenario is when your requests are very critical and you want high resilience for your Concurrent Processing Node , you can configure PCP. So if node1 goes down you still have CM node available processing your requests.

Q21. Output & Logfiles for requests executed on source Instance not working on cloned Instance?

Ans: Here is exact problem description - You cloned an Oracle Apps Instance from PRODBOX to another box with Instance name say CLONEBOX on 1st of August. You can any CM logs/output files after 1st of August only becuase these all are generated on CLONEBOX itself, But unable to view the logs/output files which are prior to 1st August. What will you do & where to check ?
Log , Output file path & location is stored in table FND_CONCURRENT_REQUESTS. Check

select logfile_name, logfile_node_name, outfile_name, outfile_node_name from fnd_concurrent_requests where request_id=&requestid ;
where requestid is id of request for which you are not able to see log or out files. You should see output like
/u01/PRODBOX/log/l123456.req, host1,/u01/PRODBOX/out/o123456.out, host1 Update it according to your cloned Instance Variables.

Q22. How to confirm if Report Server is Up & Running ?

Ans: Report Server is started by executable rwmts60 on concurrent manager Node & this file is under $ORACLE_HOME/bin .execute command on your server like
ps -ef | grep rwmts60
You should get output like
applmgr ....... rwmts60 name=REP60_VISION
where VISION is your Instance name.
Else you can submit a request like "Active Users" with display set to PDF, check output & log file to see if report server can display PDF files.

Q23. What is difference between ICM, Std Managers & CRM in Concurrent Manager ?

Ans: # ICM stand for Internal Concurrent Manager, which controls other managers. If it finds other managers down , it checks & try to restart them. You can say it as administrator to other concurrent managers. It has other tasks as well.
# Standard Manager These are normal managers which control/action on the requests & does batch or single request processing.
# CRM acronym for Conflict Resolution Manager is used to resolve conflicts between managers & request. If a request is submitted whose execution is clashing or it is defined not to run while a particular type of request is running then such requests are actioned/assigned to CRM for Incompatibilities & Conflict resolution.

Q24. What is use of Apps listener ? How to start Apps listener ? How to confirm if Apps Listener is Up & Running ?

Ans: Apps Listener usually running on All Oracle Applications 11i Nodes with listener alias as APPS_$SID is mainly used for listening requests for services like FNDFS & FNDSM.

In Oracle 11i, you have script which will start your apps listener. You can also start it by command
- lsnrctl start APPS_$SID (Replace sid by your Instance SID Name)

execute below command
lsnrctl status APPS_$SID (replcae SID with your Instance Name)
so If your SID is VISION then use lsnrctl status APPS_VISION out put should be like
Services Summary...
FNDFS has 1 service handler(s)
FNDSM has 1 service handler(s)
The command completed successfully

Q25. What is Web Listener ?

Ans: Web Listener is Web Server listener which is listening for web Services(HTTP) request. This listener is started by & defined by directive (Listen, Port) in httpd.conf for Web Server. When you initially type request like to access application here port number 80 is Web Listener port.

Q26. How will you find Invalid Objects in database ? How to compile Invalid Objects in database ?

Ans: using query
SQLPLUS> select count(*) from dba_objects where status like 'INVALID';

- using ADADMIN
- using utlrp.sql which is shipped with Oracle.

Q27. How to compile JSP in Oracle Apps ?

Ans: Using perl script shipped with Oracle apps to compile JSP files. This script is under $JTF_TOP/admin/scripts. Sample compilation method is
perl -v --compile --quiet

Q28. What is difference between adpatch & opatch ? Can you use both adpatch & opatch in Apps ?

Ans: Yes , we can use both adpatch and opatch in Apps. adpatch is an ad utility used for applying apps patches, whereas opatch is a utility used to apply rdbms patches.

Q29. Where will you find forms configuration details apart from xml file ? What is forms server executable Name ?

Ans: Forms configuration at time of startup is in script and appsweb_$CONTEXT_NAME.cfg (defined by environment variable FORMS60_WEB_CONFIG_FILE) for forms client connection used each time a user initiates forms connection.
- f60srvm is the forms executable name.

Q30. What are different modes of forms in which you can start Forms Server and which one is default ?

Ans: There are two modes in which we can start forms.
- Socket Mode
- Servlet Mode.

By Default forms are configured to start in socket mode.

Q31. How you will start Discoverer in Oracle Apps 11i ?

Ans: In order to start dicoverer you can use script under $OAD_TOP/admin/scripts/$CONTEXT_NAME
or under $ORACLE_HOME/discwb4/util (under Middle/Application Tier)

Q32. How many ORACLE HOME are Oracle Apps and whats significance of each ?

Ans: There are three $ORACLE_HOME in Oracle Apps, Two for Application Tier (Middle Tier) and One in Database Tier.
# ORACLE_HOME 1 : On Application Tier used to store 8.0.6 techstack software. This is used by forms, reports & discoverer.
ORACLE_HOME should point to this ORACLE_HOME which applying Apps Patch.
# ORACLE_HOME 2: On Application Tier used by iAS (Web Server) techstack software. This is used by Web Listener &
contains Apache.
# ORACLE_HOME 3: On Database Tier used by Database Software usually 8i,9i or 10g database.

Q33. Where is HTML Cache stored in Oracle Apps Server ?

Ans: Oracle HTML Cache is available at $COMMON_TOP/_pages for some previous versions you might find it in $OA_HTML/_pages

Q34. Where is plssql cache stored in Oracle Apps ?

Ans: sually two type of cache session & plssql stored under $IAS_ORACLE_HOME/Apache/modplsql/cache

Q35. What happens if you don't give cache size while defining Concurrent Manager ?

Ans: Lets first understand what is cache size in Concurrent Manager. When Manager picks request from FND CONCURRENT REQUESTS Queues, it will pick up number of requests defined by cache size in one shot & will work on them before going to sleep. So in my views if you don't define cache size while defining CM then it will take default value 1, i.e. picking up one request per cycle.

Q36. What are few profile options which you update after cloning ?

Ans: Rapid clone updates profile options specific to site level . If you have any profile option set at other levels like server, responsibility, user....level then reset them.

- Site Name

Q39. How to retrieve SYSADMIN password ?

Ans: If forgot password link is enabled and sysadmin account is configured with mail id user forget password link else you can reset sysadmin password via FNDCPASS.

Ans: Admin server will always reside on machine where Concurrent Processing Resides.

Q41. What is GWYUID, Where GWYUID defined & what is its used in Oracle Applications ?

Ans: GWYUID , stands for Gateway User ID and password. Usually like APPLSYSPUB/PUB
GWYUID is defined in dbc i.e. Database Connect Descriptor file . It is used to connect to database by think clients.

Q42. Whats is TWO_TASK in Oracle Database ?

Ans: TWO_TASK mocks your tns alias which you are going to use to connect to database. Lets assume you have database client with tns alias defined as PROD to connect to Database PROD on machine listening on port 1521. Then usual way to connect is sqlplus username/passwd@PROD ; now if you don't want to use @PROD then you set TWO_TASK=PROD and then can simply use sqlplus username/passwd then sql will check that it has to connect to tnsalias define by value PROD i.e. TWO_TASK

Q43. What is difference between GUEST_USER_PWD (GUEST/ORACLE) & GWYUID ?

Ans: GUEST_USER_PWD(Guest/Oracle) is used by JDBC Thin Client where as GWYUID is used by Thick Clients like via Forms Connections.

Q44. How to check number of forms users at any time ?

Ans: Forms Connections initiate f60webmx connections so you can use
ps -ef | grep f60webmx | wc -l

Q45. What is 0 & Y in FNDCPASS, FNDLOAD or WFLOAD ?

Ans: 0 & Y are flags for FND Executable like FNDCPASS & FNDLOAD where
0 is request id (request ID 0 is assigned to request ID's which are not submitted via Submit Concurrent Request Form.
'Y' indicates the method of invocation. i.e. it is directly invoked from the command-line not from the Submit Request Form.

Q46. In a Multi Node Installation, How will you find which node is running what Services ?

Ans: You can query for table FND_NODES and check for column , SUPPORT_CP ( for Concurrent Manager) SUPPORT_FORMS ( for forms server) , SUPPPORT_WEB (Web Server), SUPPORT_ADMIN( Admin Server), and SUPPORT_DB for database tier.
You can also check same from CONTEXT File (xml file under APPL_TOP/admin)

Q47. If your system has more than one Jinitiator, how will the system know, which one to pick. ?

Ans: When client makes a forms connection in Oracle Applications, forms client session uses configuration file defined by environment variable FORMS60_WEB_CONFIG_FILE also called as appsweb config file. These days this file is of format appsweb_$CONTEXT.cfg The initiator version number defined by parameter jinit_ver_name in this file will be used

Q48. While applying Apps patch using adpatch, if you want to hide the apps password, how will that be possible ?

Ans: using flags=hidepw

Q49. What is importance of IMAP Server in Java Notification Mailer ?

Ans: IMAP stands for Internet Message Access Protocol and Java Notification mailer require IMAP server for Inbound Processing of Notification Mails.

Q50. What is difference between Socket & Servlet Mode in Apps Forms ?

Ans: When forms run SOCKET Mode these are dedicated connection between Client Machine & Form Server (Started by When Forms run in servlet mode the forms requests are fulfilled by Jserv in Apache . There will be additional JVM for Forms Request in that case and you won't start form via

Q51. a. How to find OUI version ?
b. How to find Database version ?
c. How to find Oracle Workflow Cartridge Release Version ?
d. How to find opatch Version ?
e. How to find Version of Apps 11i ?
f. How to Discoverer Version installed with Apps ?
g. How to find Workflow Version embedded in Apps 11i ?
h. How to find version of JDK Installed on Apps ?

Ans: OUI
OUI stands for Oracle Universal Installer. In order to find Installer version you have to execute ./runInstaller -help ( From OUI location)
You will get output like
Oracle Universal Installer, Version Production Copyright (C) 1999, 2005, Oracle. All rights reserved.
That means OUI version in above case is
OUI location is $ORACLE_HOME/oui/bin

select * from v$version;

Oracle Workflow
Log in to the database as the owf_mgr user and issue
select wf_core.translate('WF_VERSION') from dual;

$ORACLE_HOME/OPatch/opatch version

select RELEASE_NAME from fnd_product_groups;

Discoverer with Apps installed in ORACLE_HOME same as 806 is usually 3i or 4i. To find Version login to Application Tier & go to $ORACLE_HOME/discwb4/bin and execute
strings dis4ws | grep -i 'discoverer version'

Workflow embedded in 11i
Run following SQL from apps user ;

You should see output like
Which means you are on Workflow Version 2.6.0

You can also use script wfver.sql in FND_TOP/sql to find version of workflow in Apps.

JDK in Apps
There might be multiple JDK installed on Operating System . Like JDK 1.3.1, 1.4.2 or 1.5 but in order to find which Version of JDK your Apps is using
Open your Context File $SID_$HOSTNAME.xml under $APPL_TOP/admin and look for variable
JDK_TOP oa_var="s_jdktop" what so ever value assigned against that parameter go to that directory & cd bin & execute command
./java -version so lets assume entry above is /usr/jdk then cd /usr/jdk/bin & ./java -version , you will see output like

java version "1.4.2_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_10-b03)
Java HotSpot(TM) Client VM (build 1.4.2_10-b03, mixed mode)
Which means you are using JDK 1.4.2 in Oracle Applications 11i.

Q52. If by mistake you/someone deleted FNDLIBR can this executable be restored if Yes, How & if no, what will you do ?

Ans: Yes, you can restore FNDLIBR executables
Run adadmin on concurrent manager node
select option 2. Maintain Applications Files menu
then select 1. Relink Applications programs
when prompts for
Enter list of products to link ('all' for all products) [all]
select FND
when prompt for
Generate specific executables for each selected product [No] ? YES
select YES
& from list of executables select FNDLIBR
This will create new FNDLIBR executables.

Q53. What is .pls files which you see with apps ?

Ans: pls file stands for plsql files. In apps patch these files contain code to create package spec or package body or both.

Q54. What are .ldt & .lct files which you see in apps patch or with FNDLOAD ?

Ans: .ldt & .lct stands for Loader datafile & Loader configuration files, used frequently in migrating customization, profile options, configuration data, etc.. across Instances.

Q55. What are .odf file in apps patch ?

Ans: odf stands for Object Description Files used to create tables & other database objects.

Q56. What to find Form Server log files in forms ?

Ans: Form Server Start up log file default location is $OAD_TOP/admin/log/$CONTEXT_NAME/f60svrm.txt

Q58. Is APPS_MRC Schema exists for MRC in 11.5.10 and higher ?

Ans: No , apps_mrc schema is dropped with 11.5.10 Upgrade & 11.5.10 new Install. This is replaced by more Integrated Architecture.

Q59.If APPS_MRC schema is not used in 11.5.10 and higher then How MRC is working ?

Ans: For products like Payable, Recievables which uses MRC and if MRC is enabled then each transaction table in base schema related to currency now has an assoicated MRC Subtables.

Q60. When you apply C driver patch does it require database to be Up & Why ?

Ans: Yes , database & db listener should be Up when you apply any driver patch in apps. even if driver is not updating any database object connection is required to validate apps & other schema and to upload patch history information in database tables.

Q61. Can C driver in apps patch create Invalid Object in database ?

Ans: No , C driver only copies files in File System. Database Object might be invalidated during D driver when these objects are created/dropped/modified.

Q.62 Why does a worker fails in Oracle Apps Patch and few scenarios in which it failed for you ?

Ans: This question sounds stupid but this is asked quite often in Apps DBA Interview. Apps Patch worker can fail in case it doesn't find expected data, object, files or any thing which driver is trying to update/edit/modify.

Q65. What is difference between COMPILE_ALL=SPECIAL and COMPILE=ALL while compiling Forms ?

Ans: Both the options will compile all the PL/SQL in the resultant .FMX, .PLX, or .MMX file but COMPILE_ALL=YES also changes the cached version in the source .FMB, .PLL, or .MMB file. This confuses version control and build tools (CVS, Subversion, make, scons); they believe you've made significant changes to the source. COMPILE_ALL=SPECIAL does not do this.

Q66. What is ps -ef or ps command in Unix ? for work ex < 1 yr

Ans: ps is unix/linux utility or executable to find status of process. Used mainly to find if services/process is running or not.

Q67. What is GSM in Oracle application E-Business Suite ?

Ans: GSM stands for Generic Service Management Framework. Oracle E-Business Suite consist of various compoennts like Forms, Reports, Web Server, Workflow, Concurrent Manager ..
Earlier each service used to start at their own but managing these services (given that) they can be on various machines distributed across network. So Generic Service Management is extension of Concurrent Processing which manages all your services , provide fault tolerance (If some service is down ICM through FNDSM & other processes will try to start it even on remote server) With GSM all services are centrally managed via this Framework.

Q68. What is FNDSM ?

Ans: FNDSM is executable & core component in GSM ( Generic Service Management Framework discussed above). You start FNDSM services via APPS listener on all Nodes in Application Tier in E-Business Suite.

Q69. What is iAS Patch ?

Ans: iAS Patch are patches released to fix bugs associated with IAS_ORACLE_HOME (Web Server Component) Usually these are shiiped as Shell scripts & you apply iAS patches by executing Shell script. Note that by default ORACLE_HOME is pointing to 8.0.6 ORACLE_HOME and if you are applying iAS patch export ORACLE_HOME to iAS . You can do same by executing environment file under $IAS_ORACLE_HOME

Q70. If we run autoconfig which files will get effected ?

Ans: n order to check list of files changes during Autoconfig , you can run adchkcfg utility which will generate HTML report. This report will list all files & profile options going to change when you run AutoConfig.

Q71. What is difference between .xml file & AutoConfig ?

Ans: Autoconfig is Utility to configure your Oracle Application environment. .xml file is repository of all configuration from which AutoConfig picks configuration and polulates related files.

Q72. What is .lgi files ?

Ans: gi files are created with patching along with .log files . .lgi files are informative log files containing information related to patch. You can check .lgi files to see what activities patch has done. Usually informative logs.

Q73. How will you skip worker during patch ?

Ans: f in your adctrl there are six option shown then seventh is hidden option.(If there are seven options visible then 8th option is to Skip worker depending on ad version).

Q74. Which two tables created at start of Apps Patch & drops at end of Patch ?

Ans: FND_INSTALLED_PROCESSES &AD_DEFFERED_JOBS are the tables that get updated while applying a patch mainly d or unified driver.

Q75. How to compile an Oracle Reports file ?

Ans: Utility adrepgen is used to compile Reports. Synatx is given below

adrepgen userid=apps\ source = $PRODUCT_TOP\srw\filename.rdf dest=$PRODUCT_TOP\srw\filename.rdf stype=rdffile dtype=rdffile logfile=x.log overwrite=yes batch=yes dunit=character

Q76. What is difference between AD_BUGS & AD_APPLID_PATCHES ?

Ans: AD_BUGS holds information about the various Oracle Applications bugs whose fixes have been applied (ie. patched) in the Oracle Applications installation.
AD_APPLIED_PATCHES holds information about the "distinct" Oracle Applications patches that have been applied. If 2 patches happen to have the same name but are different in content (eg. "merged" patches), then they are considered distinct and this table will therefore hold 2 records.

Q77. What exactly happens when you put an Oracle Apps instance in maintenance mode ?

Ans: Maintenance mode provides a clear separation between normal runtime operation of Oracle Applications and system downtime for maintenance. Enabling the maintenance mode feature
a) shuts down the Workflow Business Events System and
b) sets up function security so that no Oracle Applications functions are available to users.

Used only during AutoPatch sessions, maintenance mode ensures optimal performance and reduces downtime when applying a patch. (Source Metalink Note: 233044.1)

Q78. What is profile options, What are various type of profile options ?


Q79. If users complaining Oracle Applications 11i system is running slow , what all things you will check at broad level ?

Ans: All the template files, startup scripts , XML files are maintained here .

Q81. How to create User in Oracle Applications 11i ? Can you delete a User ?

Ans: New User can be created using security-->Define-->User menu. No , user cannot be deleted but can be end-dated.

Q82. What is Single Sign On ? ( If you are using portal 3.0.9 or 10G )?

Ans: As name says Single-Sign On Server is set of services (Software) which enables login to Application once which will allow you to login to Ppartner Applications with no need to login again. Lets assume I have configured single SSO Server for Portal , E-Business Suite, Collaboration Suite plus some other other applications, Now if I login to any one of them & after that if I wish to login to other applications I should be able to login without supplying passwords again.

Q83. How to configure portal with 11i ? ( If you are using portal 3.0.9 or 10G )?

Q84. What is content of dbc file & why its important ?

Ans: DBC file is quite important as whenever Java or any other program like forms want to connect to database it uses dbc file. Typical entry in dbc file is

Q85. There are lot of dbc file under $FND_SECURE, How its determined that which dbc file to use from $FND_SECURE ?

Ans: This value is determined from profile option "Applications Database ID".
The name can be picked from s_dbc_file_name in XML file.

Q86. Info Regarding Inventory.

Ans: What is oraInventory ?
oraInventory is repository (directory) which store/records oracle software products & their oracle_homes location on a machine. This Inventory now a days in XML format and called as XML Inventory where as in past it used to be in binary format & called as binary Inventory.
There are basically two kind of Inventory Global Inventory (also called as Central Inventory) and Local Inventory also called as Oracle Home Inventory.

Global Inventory ?
Global Inventory holds information about Oracle Products on a Machine. These products can be various oracle components like database, oracle application server, collaboration suite, soa suite, forms & reports or discoverer server . This global Inventory location will be determined by file oraInst.loc in /etc (on Linux) or /var/opt/oracle (solaris). If you want to see list of oracle products on machine check for file inventory.xml under ContentsXML in oraInventory (Please note if you have multiple global Inventory on machine check all oraInventory directories)

You will see entry like
HOME NAME="ORA10g_HOME" LOC="/u01/oracle/10.2.0/db" TYPE="O" IDX="1"/

Local Inventory ?
Inventory inside each Oracle Home is called as local Inventory or oracle_home Inventory. This Inventory holds information to that oracle_home only.

Can I have multiple Global Inventory on a machine ?
- Quite common questions is that can you have multiple global Inventory and answer is YES you can have multiple global Inventory but if your upgrading or applying patch then change Inventory Pointer oraInst.loc to respective location. If you are following single global Inventory and if you wish to uninstall any software then remove it from Global Inventory as well.

What to do if my Global Inventory is corrupted ?
- No need to worry if your global Inventory is corrupted, you can recreate global Inventory on machine using Universal Installer and attach already Installed oracle home by option

./runInstaller -silent -attachHome -invPtrLoc $location_to_oraInst.loc
ORACLE_HOME="Oracle_Home_Location" ORACLE_HOME_NAME="Oracle_Home_Name"

Do I need to worry about oraInventory during oracle Apps 11i cloning ?
- No, Rapid Clone will update both Global & Local Inventory with required information , you don't have to worry about Inventory during Oracle Apps 11i cloning.

Q87. What is the database holding Capacity of Oracle ?

- database holding capacity of oracle 9i is 512 pb(peta bytes)
- database holding capacity of oracle 10 g is 8 trillion tera bytes

Q88. How to find Operation System Version (Unix/Linux) ?

For solaris use command
uname -a
You will see output like
For Solaris SunOS servername 5.8 Generic_117350-23 sun4u sparc SUNW,Sun-Fire-V240
For RedHat Linux use command
cat /etc/*release*
You will see output like
Red Hat Enterprise Linux AS release 3 (Taroon Update 6)

Which means you are on Solaris 5.8 or Linux AS 3 resp.

Q89. How to find if your Operating System is 32 bit or 64 Bit ?

For solaris use command
isainfo -v
If you see out put like
32-bit sparc applications
That means your O.S. is only 32 bit but if you see output like

64-bit sparcv9 applications
32-bit sparc applications
above means your o.s. is 64 bit & can support both 32 & 64 bit applications

Q90. Can I run 64 bit application on 32 bit Operating system ?

You can run 32 bit application (like oracle application server, web server, all oracle application server are 32 bit ) on both 32 /64 bit operating system but a 64 bit application like 64 bit database can run only on 64 bit operating system.

Q91. How to find if your database is 32 bit or 64 bit(Useful in applying Patches) ?

execute "file $ORACLE_HOME/bin/oracle" , you should see output like

/u01/db/bin/oracle: ELF 64-bit MSB executable SPARCV9 Version 1
which means you are on 64 bit oracle
If your oracle is 32 bit you should see output like
oracle: ELF 32-bit MSB executable SPARC Version 1
Now you know what should be bit of patch to download

Database Upgrade from 8i to 9i

Tue, 2007-07-31 01:53
Pre-Upgrade Tasks

1) Make sure that you have 9iR2 software (9.2.0 CD Dump) before starting the installation.

first need to download the software on the server. Following are the details of the software to be downloaded:

i. for Solaris:
Disk1: Part# A99349-01
Disk2: Part# A99350-01
Disk3: Part# A99351-01
ii. for Linux
Disk1: Part# A99339-01
Disk2: Part# A99340-01
Disk3: Part# A99341-01

2) Login to orxxxxxx user and make sure that you have minimum 4 GB free space in /xxxxxx/oracle mount point. If you do not have enough free space, you need to send the TAR to SA team for adding more space to /xxxxxx/oracle mount point.

3) Make sure that you have oraInst.loc file in the below given locations and it has 777 privileges over it. If the file is not there or it does not have 777 privileges, you need to send the TAR to SA team for creating the file or granting 777 on it.
a. On Solaris: /var/opt/oracle/oraInst.loc
b. On Linux: /etc/oraInst.loc

4) Look out for the oraInventory on your instance. As per EBSO standards the location of oraInventory is “/xxxxxx/oracle/product/oraInventory”. If it is not present in this location you need to search for it. Once you know the location of oraInventory and you have privileges to update oraInst.loc file, make sure that the contents of oraInst.loc is as shown below. If the file was already existing and had some other values, just update it as shown below:

5) Make sure that you have /igold symbolic link pointing to /xxxxxx on the file system.

Preparing the System for Upgrade

1) Declare blackout on all the Components of APPS Instance and shutdown all Middle-Tier services of the instance. Keep Database server and DB listener up.

2) Check the free space in SYSTEM tablespace and if it is less than 1 GB free, add another datafile to create free space. Similarly, make sure that you have minimum 750 MB free in RBS tablespace. One example of how to add datafile is given below.

SQL> select tablespace_name, round(sum(bytes)/1024/1024) free_space from dba_free_space where tablespace_name in (‘SYSTEM’,’RBS’) group by tablespace_name;

SQL> alter tablespace SYSTEM add datafile ‘/xxxxxx/oradata02/data02/systemxx.dbf’ size 1000m autoextend on next 25m maxsize 1800m;

3) Make sure that the value of maxextents for all Rollback Segments is Unlimited. Run the below given query to check this. The value of “32765” means the Unlimited size. If the value is less than 32765 then alter the rollbacks segment to make maxextents unlimited.

SQL> select segment_name, max_extents,status from dba_rollback_segs;
SQL> alter rollback segment rbsXX storage (maxextents unlimited);

4) Set the values of following parameters in initXXXXXX.ora file as given below.
db_domain =
aq_tm_processes = 0
job_queue_processes = 0
log_archive_start = false
_system_trig_enabled = FALSE

5) Search for any “event=” set in initXXXXXX.ora or ifilecbo.ora files. If you find any event, comment that entry. Also, you may not find some of the initialization parameters given above in initXXXXXX.ora file. In that case check the parameter in ifilecbo.ora file.

6) Alter the database to NOARCHIVELOG mode and shut it down. Also shutdown the DB listener.

$ sqlplus “/ as sysdba”
SQL> shutdown immediate
SQL> startup mount
SQL> alter database noarchivelog;
SQL> archive log list
SQL> shutdown immediate
SQL> exit
$ lsnrctl stop XXXXXX

7) Create new ORACLE_HOME and set environment for that.

a. Create new directory “920” in product directory for the new HOME
$ cd /xxxxxx/oracle/product
$ mkdir 920

b. Copy the environment file from old ORACLE_HOME (817) to new ORACLE_HOME (920)
$ cd /xxxxxx/oracle/product/920
$ cp ../817/.env .

c. Edit the environment file in new ORACLE_HOME and change all the references from “817” to “920” by performing a global replace in “vi”.
$ vi .env
:1,$ s/817/920/g

d. Edit “.profile” file and “.bash_profile” (only in Linux) and edit all the references of “817” to “920”

$ cd $HOME
$ vi .profile
:1,$ s/817/920/g
$ vi .bash_profile
:1,$ s/817/920/g

e. Log out from orxxxxxx user, login again and make sure that the following environment variables are pointing to new ORACLE_HOME i.e. “/orxxxxxx/product/920”.
$ echo $TNS_ADMIN

8) At this stage we are ready to perform our upgrade. Just review all the steps in these first 2 sections and make sure that you have followed all of them. Then proceed to next section and perform the upgrade.

Performing 920 Upgrade

1) Login to orxxxxxx user and make sure that the environment variables like ORACLE_HOME, TNS_ADMIN and LD_LIBRARY_PATH are pointing to new ORACLE_HOME of 920. Also, make sure that /igold symbolic link is pointing to /xxxxxx and oraInst.loc file has been correctly updated. All these things had been discussed in the previous sections of the document.

2) Start a Reflection X session and connect to orxxxxxx user using Fsecure SSH client. Run xclock to see if you can run GUI. If you are performing the upgrade from a remote location (from India) do not run the Installer from your own PC but use VNC Viewer to connect to a Desktop in the US and then run the upgrade from the US PC. In case of Your Place customers, the normal SSH session is enabled to run GUI Installers and there is no performance hit from any location. You can run the installer without opening any Reflection or VNC viewer.

3) Start “runInstaller” from Disk1 of CD Set which has been downloaded earlier and choose the following options while installation:

a. File Locations:
ORACLE_HOME path=/igold/oracle/product/920
Do not give the actual location of 920 ORACLE_HOME (/xxxxxx/oracle/product/920) here. We are deliberately using “igold” as it helps in patching of cloned instances

b. Select a Product:
Oracle 9i Database

c. Type of Installation:
Enterprise Edition

d. Database Configuration
Software Only

4) Download PatchSet (Patch# 3095277) and unzip it in a temporary directory and run below given cpio command. It will create a new Disk1 directory.
$ unzip 9204_solaris_release.cpio.z
$ cpio -idmv < 9204_solaris_release.cpio
$ cpio -idmv < 9204_lnx32_release.cpio

5) Start “runInstaller” from /xxxxxx/oracle/product/oui directory to install PatchSet files and choose the following options:

a. Files Locations:
Source Path: /Disk1/stage/products.jar
ORACLE_HOME path=/igold/oracle/product/920

b. Choose OUI installation and complete it. Exit the installer, do not choose continue with “Next Install”. You have to restart installer.

c. Start installer again with the same File Location values as given above and choose PatchSet installation.

6) Relink Oracle executables to remove igold dependencies and verify that libraries being referenced after relinking are from correct ORACLE_HOME location and not from igold link.
$ cd $ORACLE_HOME/bin
$ ./relink all
$ ldd lsnrctl
$ ldd sqlplus
$ ldd oracle

7) Copy initXXXXXX.ora and ifilecbo.ora files from old ORACLE_HOME to new 920 ORACLE_HOME. Do not change the value of any initialization parameter; this will be done in later steps.
$ cd $ORACLE_HOME/dbs
$ cp ../../817/dbs/initXXXXXX.ora .
$ cp ../../817/dbs/ifilecbo.ora .

8) Perform the DB upgrade from 8.1.7 to 9.2.0 using the manual scripts as given below. These upgrade scripts may take 4-5 hours to complete. “startup migrate” statement will throw “ORA-32004: obsolete and/or deprecated parameter(s) specified” exception. At this point of time ignore this error it will be taken care in later steps. Once the upgrade scripts complete, query “dba_registry” table to make sure that Oracle components have been upgraded.
$ sqlplus “/ as sysdba”
SQL> startup migrate
SQL> spool db_upgrade.log
SQL> @?/rdbms/admin/u0801070.sql
SQL> spool off
SQL> spool dbcmp_upgrade.log

9) Shutdown the instance, start it up again and execute utl_recomp package to recompile invalid objects using parallel workers. This may take 3-4 hours.
a. SQL> shutdown immediate
b. SQL> startup
c. SQL> @?/rdbms/admin/utlrcmp.sql
d. SQL> exec utl_recomp.recomp_parallel(6)

10) Upgrade Oracle Text, Oracle interMedia and Orace Spatial as given in the following steps. Run “catpatch.sql” script to complete the installation of patchset. Then query dba_registry table to verify the upgrade.

JServer JAVA Virtual Machine VALID
Oracle9i Java Packages VALID
Oracle XDK for Java VALID
Oracle interMedia Text VALID
Oracle9i Real Application Clusters INVALID
Oracle interMedia VALID
Oracle Spatial VALID

11) Copy tnsnames.ora and listener.ora files from TNS_ADMIN directory of old ORACLE_HOME (817) to TNS_ADMIN directory of new ORACLE_HOME (920) and change references of 817 ORACLE_HOME to 920 ORACLE_HOME. Then start DB listener and make sure that “tnsping” works.

12) Update initXXXXXX.ora and ifilecbo.ora files as given below. These values have been taken from Note# 216205.1.

a. Update the following parameters in initXXXXXX.ora file:
