Oracle 19c is designed to meet the evolving needs of businesses by providing advanced features that enhance performance, security, and manageability. Whether for transactional processing, analytics, or mixed workloads, Oracle 19c offers a robust platform for modern database applications.

The top 3 features of Oracle 19c are:

1. Automatic Indexing

This feature uses machine learning to automatically create, rebuild, and drop indexes based on workload patterns. It continuously monitors the database to optimize query performance without manual intervention, leading to improved efficiency and reduced database tuning efforts.

2. Multitenant Architecture Enhancements

Oracle 19c allows up to 3 pluggable databases (PDBs) in a single container database (CDB) without requiring a separate license, making it easier to consolidate databases. This improves resource utilization, simplifies management, and reduces operational costs.

3. Active Data Guard DML Redirection

Enhances high availability by allowing DML (Data Manipulation Language) operations on standby databases. This means users can perform updates, inserts, and deletes on a standby database, which will be redirected to the primary database, thereby enabling read-write operations on standby systems without affecting performance.

Automatic indexing

One of 19c’s biggest selling points is the ability to perform automatic indexing. Database indexes are used to improve the speed of querying and fetching data

Oracle Data Guard

It is a feature that ensures high availability and disaster recovery for Oracle databases. Recent improvements in Oracle Data Guard enhance its functionality, making it easier and more efficient to manage.

Multitenant Architecture

Overview: In Oracle Database, the multitenant architecture allows a single container database (CDB) to hold multiple plugg chable databases (PDBs). This setup enables better resource utilization, simplified management, and improved consolidation of databases.

Automatic In-Memory Population

Enhancement in Oracle 19c is a feature designed to enhance database performance by automatically identifying and populating frequently accessed tables and their associated columns into the In-Memory column store without manual intervention from database administrators.

Long-Term Support

Oracle 19c is designated as a long-term support release, meaning it will receive updates, patches, and bug fixes for a longer period than other versions. This ensures that organizations can rely on it for stability and security over time.
