This preface lists changes in Oracle Database 2 Day + Performance Tuning Guide.
The following are changes in Oracle Database 2 Day + Performance Tuning Guide for Oracle Database 12c Release 1 (12.1).
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.
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.
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.
ASH Analytics page
Cloud Control has the ASH Analytics page, which graphically displays recent Active Session History information.
See "Determining the Cause of Spikes in Database Activity" for more information.
Cloud Control has the Real-Time ADDM page, from which you can run automatic database diagnostic monitoring in real time to diagnose problems with a slow or hung database.
See "Diagnosing Serious Performance Problems in Real Time" for more information.
