This preface lists changes in Oracle Autonomous Health Framework for Oracle Database 12c release 2 (12.2) and release 1 (12.1).
These are new features for Oracle Database 12c release 2 (12.2).
Oracle Cluster Health Advisor is introduced for Oracle Database 12c release 2 (12.2). Oracle Cluster Health Advisor collects data from Oracle Real Application Clusters (Oracle RAC) and Oracle RAC One Node databases, and from operating system and hardware resources. Oracle Cluster Health Advisor then advises how to fix database or performance issues.
These are new features for Oracle ORAchk and Oracle EXAchk 12.1.0.2.7.
This release contains several changes that simplify system and user configuration and maintenance, and upload health check collection results.
Oracle Health Check Collections Manager provides an XML bulk upload option so that you can quickly map many systems to business units.

Use the new privileged user filter to identify health checks that require a privileged user to run.

Oracle Trace File Analyzer Built on Java Runtime Environment (JRE) 1.8.
Oracle Trace File Analyzer was built on Java Runtime Environment (JRE) 1.8 for this release. It uses the latest Java features. Bash shell is no longer required for Oracle Trace File Analyzer. Because Oracle Trace File Analyzer runs on Java instead of as a shell script, it is now supported on Microsoft Windows platforms.
If you plan to use Oracle Trace File Analyzer, then JRE is now a requirement. JRE ships with Oracle Database and Oracle Grid Infrastructure. JRE is also included in the Oracle Trace File Analyzer Database Support Tools Bundle from My Oracle Support document 1513912.2.

New qosmserver to Replace OC4J J2EE Container
In earlier releases, Oracle Database Quality of Service Management Server was deployed in an OC4J J2EE container. OC4J J2EE is not supported on the latest versions of Java, and had a greater resource footprint than needed by Oracle Database Quality of Service Management. A profiled version of Tomcat, known as the qosmserver, replaces the OC4J J2EE container.
Full Support for Administrator-Managed and Multitenant Oracle RAC Databases
In Oracle Database 12c release 1 (12.1), Oracle Database Quality of Service Management supported administrator-managed Oracle RAC and Oracle RAC One Node databases in its Measure-Only and Monitor modes. In this release, you can use Oracle Database Quality of Service Management support in Management mode for administrator-managed Oracle RAC databases and Multitenant Oracle RAC Databases. However, Oracle Database Quality of Service Management cannot expand or shrink the number of instances by changing the server pool size for administrator-managed databases because administrator-managed databases do not run in server pools. Oracle Enterprise Manager Cloud Control supports this new feature in the Oracle Database Quality of Service Management pages.
