Oracle DBA 19c

Description

Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle) is a proprietary multi-model database management system produced and marketed by Oracle Corporation.

Oracle Database 19c is the final, and therefore 'long term support' release of the Oracle Database 12c family of products (which includes Oracle Database 18c). 'Long term support' means that Oracle Database 19c comes with 4 years of premium support and a minimum of 3 years extended support. Oracle Database 19c builds upon the innovations of previous releases such as Multitenant, In-Memory, JSON support, Sharding and many other features that enable Oracle’s Autonomous Database Cloud Services. This latest release of the world’s most popular database also introduces new functionality, providing customers with a multi-model enterprise-class database for all their typical use cases.

JOURNEY TO AUTONOMOUS DATABASE CLOUD Over successive database releases, Oracle has introduced innovative automated features that have helped administrators deliver a superior level of service to their end users. These innovations include: • Cost-based Optimization Automatic SQL query optimization, automatic statistics gathering, automatic query rewrite automatic SQL Plan management and automatic SQL tuning. • Performance Tuning and Diagnostics Automatic memory and resource management, automatic index and materialized view advisors, Automatic Database Diagnostic Monitor, Automatic Database Workload capture & replay and Automatic Workload Repository. • Data Optimization Automatic undo management, automatic segment space management, Automatic Storage Management, Automatic Data Optimization and automatic columnar cache. • Cloud-Scale Operation. Automatic standby management (broker), Diagnostic Framework, Multitenant Architecture, automatic database clone refresh and machine learning in Cluster Health Advisor. In March 2018, Oracle introduced the Autonomous Data Warehouse (ADW) cloud service, and this was followed in August 2018 with the introduction of the Autonomous Transaction Processing (ATP) cloud service. By utilizing automated database functionality with machine-learning techniques, these Autonomous Database Cloud services can provide a level of performance and reliability that manually managed databases struggle to deliver. The Oracle Autonomous Database is specifically designed to provide customers with a higher level of service at lower cost by automating routine administrative tasks and eliminating human error through: • Self-Driving. With easy to define workloads and policies, automation then makes them happen. • Self-Securing. With automated protection from both external attacks and internal users. • Self-Repairing. With automated protection from all downtime. The Oracle Autonomous Database is built on top of the world’s most widely proven enterprise-class database: Oracle Database, it runs on the world’s best database platform: Oracle Exadata, and available as pay-as-you-go services on Oracle Cloud and Exadata Cloud at Customer (for public cloud and private cloud deployment respectively). In addition, machine learning for performance diagnostics and recovery optimizations are built into each layer of the deployment stack
