Oracle 19c is a stable, long-term support (LTS) release of the Oracle Database, known for its reliability, performance enhancements, multi-tenant architecture, and extensive features for relational and non-relational data (JSON, XML, spatial), serving as a solid choice for production environments needing extended support beyond newer, innovation-focused releases like 21c and 23c, with options for extended support for many years.
Key Characteristics
Long-Term Support (LTS): Designed for stability, it’s the recommended choice for production systems needing long support cycles, unlike shorter-term innovation releases.
Performance: Offers significant improvements in query efficiency, resource utilization, and automation over previous versions like 12c.
Multi-Tenant Architecture: Built on the 12c multi-tenant foundation, enabling container databases (CDBs) and pluggable databases (PDBs) for easier management.
Multi-Model Capabilities: Supports various data types, including relational, JSON, XML, text, spatial, and graph data.
Enhanced Features: Includes innovations like DISTINCT in LISTAGG, improved JSON-to-SQL mapping, and easier PDB management via Database Configuration Assistant (DBCA).
Support & Versions
Release Strategy: Part of the 12c family but released in 2019, aligning with the year.
Support Lifecycle: Offers extended support options, allowing companies to stay on 19c longer without immediate upgrades, with support extending well into the 2030s for some customers.
Comparison: Positioned as the stable choice, while 21c and 23c (like 23ai) are innovation releases for exploring new features.
Usage
Environments: Widely used for enterprise-level data management, development, and mission-critical applications.
Availability: Downloadable for various operating systems (Windows, Linux, AIX, etc.) in different formats (ZIP, RPM).
