Tackling the challange of Provisoning Databases in an agile datacenter

Wed, 2014-05-14 02:03

One of the key task that a DBA performs repeatedly is Provisioning of Databases which also happens to one of the top 10 Database Challenges as per IOUG Survey .

Most of the challenge comes in form of either Lack of Standardization or it being a Long and Error Prone Process . This is where Enterprise Manager 12c can help by making this a standardized process using profiles and lock-downs ; plus have a role and access separation where lead dba can lock certain properties of database (like character-set or Oracle Home location  or SGA etc) and junior DBA's can't change those during provisioning .Below image describes the solution :

In Short :

  • Its Fast

  • Its Easy 

  • And you have complete control over the lifecycle of your dev and production resources.

I actually wanted to show step by step details on how to provision a 11204 RAC using Provisioning feature of DBLM  , but today i saw a great post by MaaZ Anjum that does the same , so i am going to refer you to his blog here :

EMCLI setup

Mon, 2014-04-28 03:15

A quick note on how to install EMCLI which is used for various CLI operations from EM . I was looking to test some Database provisioning automation via EMCLI and thus was looking to setup the same . 

To set up EMCLI on the host, follow these steps:
1.    Download the emcliadvancedkit.jar from the OMS using URL https://<omshost>:<omsport>/em/public_lib_download/emcli/kit/emcliadvancedkit.jar
2.    Set your JAVA_HOME environment variable and ensure that it is part of your PATH. You must be running Java 1.6.0_43 or greater. For example:
o    setenv JAVA_HOME /usr/local/packages/j2sdk
o    setenv PATH $JAVA_HOME/bin:$PATH
3.    You can install the EMCLI with scripting option in any directory either on the same machine on which the OMS is running or on any machine on your network (download the emcliadvancedkit.jar to that machine)
java -jar emcliadvancedkit.jar client -install_dir=<emcli client dir>
4.    Run emcli help sync from the EMCLI Home (the directory where you have installed emcli) for instructions on how to use the "sync" verb to configure the client for a particular OMS.
5.    Navigate to the Setup menu then the Command Line Interface. See the Enterprise Manager Command Line Tools Download page for details on setting EMCLI.

Webcast: Database Cloning in Minutes using Oracle Enterprise Manager 12c Database as a Service Snap Clone

Thu, 2014-04-17 05:02

Since the demands
from the business for IT services is non-stop, creating copies of production
databases in order to develop, test and deploy new applications can be
labor intensive and time consuming. Users may also need to preserve private
copies of the database, so that they can go back to a point prior to when
a change was made in order to diagnose potential issues. Using Snap Clone,
users can create multiple snapshots of the database and “time
” across these snapshots to access data from any point
in time.

Join us for an in-depth
technical webcast and learn how Oracle Cloud Management Pack for Oracle
Database's capability called Snap Clone, can fundamentally improve the
efficiency and agility of administrators and QA Engineers while saving
CAPEX on storage. Benefits include:

  • Agile provisioning
    (~ 2 minutes to provision a 1 TB database)

  • Over 90% storage

  • Reduced administrative
    overhead from integrated lifecycle management

OAM-OIM integration (both 11g)

Tue, 2010-12-14 17:58

Next up i will be covering OAM-OIM integration for 11g .

Why do we need Integration?
Oracle Identity Manager(OIM) is an Identity Administration solution which Enables management of users and organizational identities with their associated attributes.

Oracle Access Manager(OAM) is an Access Management solution which Facilitates authentication of resource-related accounts for users and organizations, and allow users and organizations to access their accounts by authorizing them .

OIM and OAM are integrated together to provide a complete Identity and Access Solution

I will start with Architecture & then steps involved for integration in coming post ...

Upgrade 10g Osso to 11g OAM (Part 2)

Sun, 2010-12-12 16:29

This is part 2 of

So last post we saw the overview of upgrading osso to oam11g . Now some more details on same .

As we are using the co-existence feature , we have to install the OAM server and upgrade the existing OSSO 10g server to the OAM servers.

OAM Upgrade Steps Overview
Pre-Req : You already have a OAM 11g Installed
Upgrade Step 1: Configure User Store & Make it Primary
Upgrade Step 2: Create Policy Domain , this is dome by UA automatically
Upgrade Step 3: Migrate Partners : This is done by running Upgrade Assistant
Verify successful Upgrade


Details on UA step :
To Upgrade the existing OSSO 10g servers to OAM server , this is done by running the UA script in OAM , which copies over all the partner app details from osso to OAM 11g , is the script name which will ask you to input the from SSO $OH/sso/config folder of osso 10g & other variables like db password .

Some pointers

  • Upgrading oso to Oam 11g , by default enables the coexistence mode on the OAM Server

  • Front-end the OAM server with the same Load Balancer that is the front end of the OSSO 10g servers.

  • Now, OAM and OSSO 10g servers are working in a co-exist mode.
  • OAM 11g is made to understand 10g OSSO Token format and session handling capabilities so as to co-exist with 10g OSSO servers.<>/li

How to test ?

Try to access the partner applications and verify that single sign on works. Also, verify that user does not have to login in if the user is already authenticated by either OAM or OSSO 10g server.

Screen-shots & Troubleshooting tips to be followed .......

Upgrade 10g Osso to 11g OAM

Sat, 2010-11-20 18:08
As described earlier , Oam 11g is a replacement of 10g osso in IDM suite . In OAM 11g there is a new feature called Co-exist in where you can do step-up replacement of osso environment , ie , a phased migration approach where only one 10g OSSO instance is migrated to 11g OAM at a time.

To be frank , this is a really cool feature specially when you want to upgrade production & don't want a downtime while migration . I will be taking through the step-by-step details on the same , but before that here is an overview .

Typical OSSO Server Deployment Topology
A Cluster of 10g SSO Servers Front-ended by a Load Balancer (LBR)


User accesses a protected resource , Agent intercepts it and redirects to the LBR
->LBR routes the request to one of the SSO Servers in the cluster
->The SSO Server authenticates and sets a SSO_ID Cookie containing the session state.

10g Osso Topology

Now with Co-existance , we can use phase migration approach & replace the osso server with OAM 11g servers one by one .The cluster now will have both 10g SSO Servers and 11g OAM Server(s) ( till all the servers are upgraded )

OSSO 10g - OAM 11g Co-existence

So whats the problem?
  • 10g SSO Server sets a SSO_ID cookie
  • 11g OAM Server sets an OAM_ID cookie
  • They don't understand each other's cookies . They don't honor sessions created by each other.
  • Single Sign on wouldn't work

Solution 11g OAM Server should also
  • Understand the 10g SSO Cookie
  • Create/Update the 10g SSO Cookie
To Be continued ............

Why should i upgrade to oam 11g ?

Tue, 2010-11-02 00:37

One of my reader has some questions :

1)I use osso , what is oam ? Why should i upgrade to oam 11g ?
2)Can i upgrade from oam 10g to oam11g ?

So here are the details
1) You should look to upgrade to oam11g as osso will not be supported after 2011 (or will need extended support) . OAM 11g is the supported product that will replace the osso in fusion middle-ware . So if you are running osso 10g , you should start looking at upgrade options .

2)Current rollout of 11g oam is intended for osso customers mostly . So you can wait for further announcements or follow-up with PM team.

Bird's eye view of OAM 11g Install process

Thu, 2010-10-28 01:09

Bird's eye view of OAM 11g Install process

Configuration process requires 2 steps
1)Database schema configuration using Repository Creation Utility (RCU)
2)Product install , configuration and deployment using WebLogic Configuration Wizard

Database schema configuration
RCU allows customers to choose the product for which they want to create database schema and creates the schema after providing the database details

OAM Product install , configuration and deployment
OAM 11g installs using Oracle Universal Installer (OUI) , The installation process copies all the software bits to the host machine but. does not perform product configuration

OAM 11g is a J2EE application that deploys into a container ,The deployment and configuration is handled by WebLogic Configuration Wizard by using configuration templates provided by each product to configure the product .Finally, it deploys the product into a new or existing WLS domain.

11g OAM , bind or compare for authentication ?

Sun, 2010-10-17 18:27

I had this question in mind when i started looking at 11g OAM .
bind or compare for authentication ? And Why ?

So what i found .......
11g OAM uses Ldapcompare
why ? because
An ldapcompare works like an ldapbind as far as username /password check is concerned, it doesnt create a session an thus is far more efficient that using ldapbind for a server to authenticate multiple users

How to get mail working with Apex packed with 11g ..

Tue, 2008-07-22 22:44

Hi , Recently i installed 11g db on one of my systems ,as it comes with APEX i thought to move my apex app(which were in 10g) to the same .........when i moved my apps , i got everything working but mail gave error :ORA-24247: network access denied by access control list (ACL)

The issue is with ACL as by default, the ability to interact with network services is disabled in Oracle Database 11g. To enable i needed to run a procedure as shown below .

-- Look for the ACL currently assigned to '*' and give FLOWS_030000
-- the "connect" privilege if FLOWS_030000 does not have the privilege yet.


-- Before checking the privilege, make sure that the ACL is valid
-- (for example, does not contain stale references to dropped users).
-- If it does, the following exception will be raised:
-- ORA-44416: Invalid ACL: Unresolved principal 'FLOWS_030000'
-- ORA-06512: at "XDB.DBMS_XDBZ", line ...
SELECT SYS_OP_R2O(extractValue(P.RES, '/Resource/XMLRef')) INTO ACL_ID
WHERE extractValue(P.RES, '/Resource/XMLRef') = REF(A) AND

'connect') IS NULL THEN
'FLOWS_030000', TRUE, 'connect');

-- When no ACL has been assigned to '*'.
'ACL that lets power users to connect to everywhere',
'FLOWS_030000', TRUE, 'connect');

Finally got it working :)
