Oracle Database 19c is the long-term support release of the 12c family, focusing heavily on automation hybrid data management

. For developers and DBAs looking for technical details often found in PDF guides, here are the essential new features and enhancements. ResearchGate 1. Automation & Performance

The most significant shift in 19c is the move toward "Autonomous" behavior, even for on-premises installations. IT Convergence Automatic Indexing:

Uses machine learning to capture, identify, and verify candidate indexes. It validates them against the workload and only implements them if they improve performance, reducing manual tuning significantly. Real-Time Statistics:

Traditionally, statistics were gathered during maintenance windows. 19c gathers them "on-the-fly" during conventional DML operations (Insert/Update/Merge), ensuring the optimizer has up-to-date information for better execution plans. SQL Quarantine:

To prevent "runaway" queries from exhausting system resources, 19c can automatically quarantine SQL statements that exceed specific resource thresholds, preventing them from running again until addressed. Oracle Blogs 2. SQL & Application Development

Simplified JSON Support: 19c simplifies JSON syntax, allowing for more intuitive querying of document-style data directly within a relational environment. It also introduces a native JSON data type and supports materialized views for queries containing JSON_TABLE, significantly boosting performance for document-heavy applications.

REST-Enabled SQL: Developers can now interact with the database via RESTful APIs, allowing SQL statements to be executed over HTTP, which is essential for cloud-native application development. Performance and Automation
