Changes in This Release for Oracle Database 2 Day + Performance Tuning Guide

New Features

The following features are new in this release:

• Real-time database operations monitoring

  Real-Time database operations monitoring tracks and reports on active and recently completed database operations. You can monitor details of the execution of a single SQL or PL/SQL statement. You can also monitor the progress of long-running operations such as a batch job, or extract, transform, and load (ETL) processing.

  See "Monitoring Real-Time Database Operations" for information on this feature.

Desupported Features

Oracle Enterprise Manager Database Control is no longer supported by Oracle. See Oracle Database Upgrade Guide for a complete list of desupported features in this release.

Other Changes

The following are additional changes in the release:

• Oracle Enterprise Manager Cloud Control

  In previous releases of Oracle Database, you used Oracle Enterprise Manager Database Control (Database Control) to manage database performance tuning from a graphical user interface. In this release, you can use the Oracle Enterprise Manager Cloud Control (Cloud Control) graphical user interface. Cloud Control provides more functionality than Database Control. The procedures in this guide use Cloud Control.

  You must install Cloud Control separately from Oracle Database.
