Immutable Data Integrity with Oracle's Blockchain Tables

Sat, 2024-03-02 16:24

 Blockchain tables in Oracle Database implement a unique data organization model, forming chains of insert-only rows. Each row, excluding the first, links back to the previous row using cryptographic hashing. This hashing method leverages row data and the hash of the preceding row to identify any unauthorized modifications through specialized verification procedures. The added capability to store user signatures significantly enhances security against tampering and unauthorized alterations.

Beyond thwarting unauthorized changes initiated by rogue or compromised insiders, blockchain tables boast powerful functionality:


  • Identification of illicit modifications made by circumventing Oracle Database protocols.
  • Detection of user impersonation and unauthorized data insertions on behalf of another user.
  • Safeguarding against data tampering, certifying that all data inserted into the table was done legitimately.
  • The chaining mechanism ensures that each row remains linked to its predecessor through cryptographic hashing. Altering any row disrupts this chain, immediately signaling tampering. However, this additional layer of security necessitates increased processing time during commit operations to chain rows effectively.


Let's explore how to create and interact with a blockchain table in Oracle Database through the following example:


-- Creating a blockchain table

SQL> CREATE BLOCKCHAIN TABLE secure_data_table (data_value VARCHAR2(128), sequence_number NUMBER)

     NO DROP UNTIL 1 DAYS IDLE

     NO DELETE UNTIL 16 DAYS AFTER INSERT

     HASHING USING "SHA2_512" VERSION "v1";    

Table created.


-- Inserting data into the blockchain table

SQL> INSERT INTO secure_data_table VALUES ('Value1', 1);

1 row created.


SQL> COMMIT;

Commit complete.


-- Querying metadata of the blockchain table

SQL> SELECT column_id, column_name, nullable, hidden_column

     FROM all_tab_cols

     WHERE table_name LIKE 'SECURE_DATA_%'

     ORDER BY column_id;


-- Viewing blockchain table details

SQL> SELECT * FROM dba_blockchain_tables;

In this example, secure_data_table is our blockchain table, ensuring immutable data integrity and providing robust security against unauthorized changes. The SHA2_512 hashing algorithm is employed to maintain the integrity of each chained row, guaranteeing data authenticity and traceability within Oracle Database's secure environment.

Access AWS S3 Bucket from Oracle Database

Thu, 2024-02-29 16:11

 If you want to access any object stored in an AWS S3 bucket from Oracle database, then dbms_cloud package is your friend, provided you are using Oracle Autonomous database. 

An AWS S3 (Simple Storage Service) bucket is a scalable storage resource in the cloud provided by Amazon Web Services. It allows you to store and retrieve any amount of data from anywhere on the web. S3 buckets are highly durable, secure, and can be configured to support various use cases including website hosting, data backup, and content distribution.

The DBMS_CLOUD package in Oracle Database is a PL/SQL package that provides procedures to interact with Oracle Cloud Infrastructure services, specifically for loading data into Oracle Database from external data sources such as object storage in Oracle Cloud. It enables seamless integration between Oracle Database and cloud-based storage for data loading operations, making it easier to ingest large volumes of data into the database from cloud-based sources. The package includes procedures like COPY_DATA for copying data from cloud storage to database tables, and CREATE_CREDENTIAL for managing credentials needed to access cloud storage securely. This package simplifies data loading tasks and enhances integration capabilities between Oracle Database and Oracle Cloud services.

In order to access the object from S3 bucket, make sure you have created a database user in Oracle with proper credentials, and also you have AWS IAM credentials to access S3 bucket.

Step 1: First, you need to create a credential in Oracle Database that allows access to your AWS S3 bucket. This credential will store the AWS access key ID and secret access key securely.


BEGIN

  DBMS_CLOUD.CREATE_CREDENTIAL(

    credential_name => 'MY_AWS_CREDENTIAL',

    username => 'AWS_ACCESS_KEY_ID',

    password => 'AWS_SECRET_ACCESS_KEY'

  );

END;

/

Step 2: Now, you can use the DBMS_CLOUD package to select data from a file in your AWS S3 bucket and load it into a table in Oracle Database.


DECLARE

  v_data CLOB;

BEGIN

  v_data := DBMS_CLOUD.GET_OBJECT(

    credential_name => 'MY_AWS_CREDENTIAL',

    object_uri => 'https://s3.<region>.amazonaws.com/<bucket_name>/<file_key>'

  );

  -- Process the retrieved data (example: print the data)

  DBMS_OUTPUT.PUT_LINE(v_data);

END;

/

Enjoy.

How AI Transcription Can Make Your Next Job Interview More Effective

Thu, 2024-02-29 01:47

 If you are looking to use AI Transcription during your job interview to get help from LLM, then this video is going to help you immensely.





In the rapidly evolving landscape of recruitment, the integration of Artificial Intelligence (AI) tools has been a game-changer, especially AI transcription services. These services, which convert speech into a written or electronic text document, are now being increasingly utilized during candidate interviews. This innovative approach is not just about efficiency; it's about transforming the interview process into a more insightful, fair, and strategic component of talent acquisition. Let's delve into the merits of using AI transcription in candidate interviews and how it is reshaping the future of hiring.

Enhanced Accuracy and Objectivity

One of the paramount benefits of using AI transcription is the enhanced accuracy and objectivity it brings to the recruitment process. Traditional note-taking methods during interviews are inherently flawed, prone to human error, and can be biased. AI transcription, on the other hand, captures every word as it is spoken, ensuring that nothing is missed or misinterpreted. This verbatim record allows hiring managers to review the interview with a fine-tooth comb, ensuring that decisions are made based on what was actually said, rather than on recollection or interpretation.

Improved Candidate Experience

The candidate experience is crucial in attracting top talent. AI transcription contributes to a more engaging and less intimidating interview environment. Candidates can speak freely, knowing that their responses are being accurately recorded. This level of precision in capturing responses allows candidates to feel heard and valued, improving their overall experience and perception of the company. Furthermore, the efficiency of AI transcription speeds up the interview process, enabling quicker feedback and follow-ups, which candidates appreciate.

Accessibility and Inclusivity

AI transcription makes interviews more accessible and inclusive, breaking down barriers for candidates who may be deaf or hard of hearing. By providing real-time transcription, these candidates can participate fully in the interview process, ensuring equal opportunities for all. This commitment to inclusivity not only enhances the company's reputation but also widens the talent pool by making it more diverse.

Streamlined Analysis and Decision Making

The comprehensive data captured by AI transcription allows for a more streamlined analysis of candidates' responses. Hiring teams can utilize this data to identify patterns, evaluate key competencies, and make more informed decisions. AI tools can also highlight specific skills and qualifications mentioned during the interview, making it easier to assess candidates against job requirements. This data-driven approach reduces the likelihood of cognitive biases affecting hiring decisions and helps in selecting the best fit for the role.

Enhanced Collaboration Among Hiring Teams

AI transcription facilitates better collaboration among hiring team members, especially in scenarios where not all members can attend every interview. The transcribed interviews can be easily shared, allowing team members to review and provide input at their convenience. This collaborative approach ensures a more comprehensive evaluation of candidates, drawing on diverse perspectives within the team.

Legal Compliance and Record-Keeping

In today's litigious environment, maintaining accurate records of candidate interviews can be crucial for legal compliance. AI transcription provides an exact record of the conversation, which can be invaluable in defending against claims of discrimination or bias. This level of documentation ensures that the hiring process is transparent and defensible, safeguarding the company against potential legal challenges.

Conclusion

The adoption of AI transcription in candidate interviews is more than just a nod to technological advancement; it's a strategic move towards making the recruitment process more accurate, fair, and inclusive. By enhancing the accuracy of interviews, improving candidate experience, and streamlining decision-making, AI transcription is setting a new standard in talent acquisition. As companies continue to seek competitive advantages in attracting top talent, the use of AI in recruitment processes, especially transcription, is likely to become not just common but essential.

 Oracle Database seamlessly integrates JSON (JavaScript Object Notation) with its robust RDBMS features, offering full support for transactions, indexing, declarative querying, and views among other functionalities.


JSON is a lightweight data interchange format widely employed for representing structured data due to its human-friendly readability and machine-friendly parsing capabilities. It utilizes key-value pairs enclosed in curly braces {}. Each key is a string followed by a colon :, and its value can be a string, number, boolean, array, object, or null. JSON arrays are ordered lists enclosed in square brackets [], while objects represent collections of key-value pairs. This versatile format finds extensive use in web development, APIs, and system-to-system data exchanges owing to its simplicity, adaptability, and clarity—a near subset of JavaScript's object literal notation.


When leveraging JSON within Oracle Database, the typical workflow involves:


Step 1: Creating a JSON-Enabled Table:


CREATE TABLE json_purchase_orders

  (id VARCHAR2(32) NOT NULL PRIMARY KEY,

   date_loaded TIMESTAMP WITH TIME ZONE,

   po_document JSON);



Step 2: Inserting JSON Data into the Table:


INSERT INTO json_purchase_orders

  VALUES (SYS_GUID(),

          TO_DATE('30-DEC-2014'),

          '{"PONumber": 1600,

            "Reference": "ABULL-20140421",

            "Requestor": "Alexis Bull",

            "User": "ABULL",

            "CostCenter": "A50",

            "ShippingInstructions": {...},

            "SpecialInstructions": null,

            "AllowPartialShipment": true,

            "LineItems": [...]}');


Step 3: Querying JSON Data from the Table:


SELECT po.po_document.PONumber

FROM json_purchase_orders po;


By leveraging Oracle Database's native JSON support, developers gain the flexibility to seamlessly integrate JSON data within the relational model, enabling efficient storage, retrieval, and manipulation of JSON documents alongside traditional SQL operations. This unified approach empowers enterprises to harness the best of both worlds—structured data management and JSON flexibility—within a single, powerful database environment.

How to Identify Oracle Database Orphan Sessions

Fri, 2024-01-26 00:17

 In the world of database management, particularly with Oracle databases, "orphan sessions" are a common issue that can affect performance and resource utilization. 

In Oracle databases, an orphan session, sometimes known as a "zombie session," is a session that remains in the database even though its corresponding client process has terminated. These sessions no longer have a user actively interacting with them, yet they consume system resources and can hold locks, leading to performance degradation and blocking issues.

Orphan sessions can occur due to various reasons such as:

  • Network issues that disrupt the connection between the client and the server.
  • Application or client crashes that terminate the session abnormally.
  • Database bugs or misconfigurations.

Queries to Identify Orphan Sessions:

SELECT s.sid, s.serial#, p.spid, s.username, s.program
FROM v$session s
JOIN v$process p ON p.addr = s.paddr
WHERE s.type != 'BACKGROUND';

This query lists active sessions, excluding background processes. It provides session identifiers (sid, serial#), the operating system process identifier (spid), and the username and program name. Orphan sessions often show NULL or unusual entries in the program column.

SELECT s.sid, s.serial#, p.spid, s.username, s.program
FROM v$session s
JOIN v$process p ON p.addr = s.paddr
WHERE s.type != 'BACKGROUND'
AND NOT EXISTS (SELECT NULL FROM v$process WHERE spid = s.process);

This query filters the sessions where the client process (spid) associated with the session does not exist in the v$process view, indicating a potential orphan.


SELECT s.sid, s.serial#, l.object_id, o.object_name, o.object_type
FROM v$session s
JOIN dba_objects o ON o.object_id = l.object_id
JOIN v$lock l ON s.sid = l.sid
WHERE s.sid IN (SELECT sid FROM v$session WHERE ... /* Conditions from above queries */);


This query identifies locks held by sessions suspected to be orphans, which is useful for understanding the impact of these sessions on the database.

How to Manage Orphan Sessions:

Manual Termination: Using the ALTER SYSTEM KILL SESSION command to terminate the identified orphan sessions. Or Kill at OS level with kill -9 spid command.

Automated Monitoring and Cleanup: Implementing automated scripts or database jobs to periodically identify and clean up orphan sessions.

Prevention: Addressing the root causes, such as network stability and application robustness, can reduce the occurrence of orphan sessions.
