ORCACLE 23AI :

 

Oracle Database 23ai introduces numerous features valuable for DBAs, including AI-powered enhancements, improved developer productivity tools, and broader support for modern data types and paradigms. Key features include AI Vector Search, JSON Relational Duality, SQL macros, and enhancements to existing functionalities like In-Memory and Data Guard.

Here’s a more detailed look at the features relevant to DBAs:

AI and Machine Learning Integration:

• AI Vector Search:

Enables semantic searches within the database, allowing users to query data based on meaning rather than just keywords.

• Smarter Performance Tuning:

Oracle 23ai leverages AI for improved timing estimates and resource costings, leading to more efficient database operations.

• Anomaly Detection and Predictive Maintenance:

AI capabilities can be used to identify unusual patterns and predict potential issues, aiding in proactive maintenance.

Developer Productivity and SQL Enhancements:

• SQL Macros:

Allow for the creation of reusable SQL code snippets, promoting code reuse and simplifying complex queries.

• JSON Relational Duality:

Provides a way to work with both relational and JSON data within the same application, simplifying development and data management.

• Enhanced JSON Support:

Oracle 23ai includes advanced JSON functions, improved indexing, and efficient binary storage options.

• Boolean Data Type:

Supports the standard Boolean data type for storing true/false values, simplifying application logic and data representation.

• Direct Joins for UPDATE and DELETE:

Allows for joining tables directly in UPDATE and DELETE statements, making data manipulation more efficient.

• GROUP BY Column Alias:

Enables the use of column aliases or positions in GROUP BY clauses, improving query readability.

• IF [NOT] EXISTS:

Provides a convenient way to create, modify, or delete database objects conditionally, preventing errors and simplifying scripting.

Performance and Scalability:

• Enhanced In-Memory Features: Automatic In-Memory (AIM) is enhanced with automatic Join Group creation, In-Memory Optimized Arithmetic, and Bloom filter optimizations.
• Automatic In-Memory Sizing: The In-Memory column store can now be dynamically managed by Automatic Shared Memory Management (ASMM).
• True Cache: Provides read-only access to data at high speeds across multiple servers.
• Fast Ingest Enhancements: Improvements to Memoptimized Rowstore Fast Ingest with support for partitioning, compressed tables, and direct in-memory population.
• Lock-Free Reservations: Offers high-speed, lock-free reservations for concurrent data access.

Security and Compliance:

Enhanced Security Features:

23ai includes tighter data protection, advanced auditing, and new encryption capabilities, including AES256 encryption.

• SQL Firewall:

.Opens in new tab

Provides an embedded network firewall within the database for enhanced security.

High Availability and Distributed Databases:

• RAFT Replication:

Oracle Globally Distributed Database now supports RAFT replication for improved data consistency and availability.

• CMAN-TDM:

Oracle’s database connection proxy, CMAN-TDM, provides per-PDB pooling capabilities.

Other Notable Features:

• Materialized View Support for ANSI Joins: Materialized views now support query rewrites for statements using ANSI or Oracle style joins.
• MAX_COLUMNS Initialization Parameter: Increases the maximum number of columns per table to 4096.
