ClassNew Feature
CompatibilityCompatible - no manual interaction needed

The plugin is able to work with Grid-Infrastructure and Oracle Restart for Version 12.2+. There is no guarantee that the oratab has valid entries anymore. In most configurations the data for ASM and instances are missing from 18c onwards. The plugin reads the ORACLE_HOME from the cluster registry. This also makes the plugin compatible for Clusters with policy managed databases, which was not supported in previous versions. Mostly known in environments with '_1' at the end of the ORACLE_SID in oratab.

Incompatible Change: Please be aware that this feauture must be disabled in installations with Oracle Grid Infrastructure and custom scripts for Failover Clusters. These type of installation is rare and need a valid configuration in oratab and as a result the automatic gathering of ORACLE_HOME from the cluster repository must be disabled. Please set the variable OLRLOC in mk_oracle.cfg to a non existing file or /dev/null to disable this feauture. Real Application Clusters or Oracle Restart with version 11.2+ are not affected. Please disable it for CRS 10.1-11.1 as well. This change can be ignorred in normal single Instance installations without Grid Infrastructure or Oracle Restart - mostly known as installations without ASM.
