2.9 Enhanced Cluster Health Advisor Support for Oracle Pluggable Databases

The Cluster Health Advisor (CHA) diagnostic capabilities have been extended to support 4K PDBs, up from 256 in Oracle Database 23ai.

Going forward, this is crucial for Oracle Autonomous Database deployments. CHA's problem detection and root cause analysis will be improved by considering DB events such as reconfiguration. This improves detection, analysis, and targeted preventative actions for problems such as instance evictions.
