New Features of Oracle 19c

New Features of Oracle 19c-

Oracle Database 19c refers to the 19th version of the Oracle Database, which is a relational database management system (RDBMS) developed and marketed by Oracle Corporation. The "c" in 19c stands for "Cloud," indicating Oracle's commitment to cloud computing and cloud-based solutions. Oracle 19c is the successor to Oracle Database 18c and comes with several new features, enhancements, and improvements over its predecessors.

Oracle Database 19c, released by Oracle Corporation, brought several significant features and enhancements to improve performance, manageability, and security. Here's a more detailed explanation:

 

 

Multitenant Architecture Enhancements:

Oracle 19c focused on enhancing its Multitenant Architecture, allowing for more efficient management and consolidation of databases. Notable improvements included features like PDB snapshots, hot cloning, and cross-container operations, streamlining administrative tasks.

 

Automatic Indexing:

A major highlight was the introduction of Automatic Indexing. This feature employs machine learning algorithms to automatically create and fine-tune indexes based on the observed workload patterns, simplifying the database optimization process.

 

Real-Time Statistics:

The addition of Real-Time Statistics aimed at improving query optimization. This feature ensures that the query optimizer has access to the most up-to-date statistics, particularly beneficial for partitioned tables.

 

SQL Quarantine:

Oracle 19c introduced SQL Quarantine, a feature designed to prevent the execution of SQL statements identified as problematic. This helps safeguard the database from potential performance issues caused by problematic queries.

 

In-Memory Database Enhancements:

Oracle Database In-Memory received enhancements, making it more versatile for both analytics and mixed workload environments. These improvements contributed to faster query performance and improved overall efficiency.

 

Blockchain Tables:

The introduction of Blockchain Tables aimed at simplifying the development and management of blockchain-enabled applications within the Oracle Database environment.

 

Enhanced Security Features:

Security received attention with various enhancements, including the introduction of new algorithms for Transparent Data Encryption (TDE), improvements in Data Redaction, and better integration with Oracle Key Vault for enhanced data protection.

 

JSON Enhancements:

Oracle 19c improved support for working with JSON data, introducing features like JSON_TRANSFORM, JSON_TABLE, and JSON_EXISTS, making it more seamless to work with JSON documents within the database.

 

Shading Enhancements:

Oracle Shading, a feature enabling the distribution and management of data across multiple discrete Oracle databases, saw improvements in manageability and performance, providing a more robust and scalable solution.

 

Database Replay:

The Database Replay functionality was enhanced, allowing for more effective testing and validation of database changes before implementing them in a production environment, reducing the risk of potential issues.

 

Machine Learning in the Database:

Oracle 19c integrated machine learning algorithms directly into the database. This inclusion allowed users to perform tasks such as predictive analysis, anomaly detection, and clustering without the need for external tools, bringing machine learning capabilities closer to the data.
