Upgrading Configuration that includes Berkeley Database - Oracle GoldenGate 12.2 or later

When you are upgrading Oracle GoldenGate from release 12.1.2.1 to 12.3.0.1 and have enabled monitoring and the datastore is created by the Performance Metrics server, the best practice is to purge the data store before performing the upgrade. After the upgrade, the datastore is recreated. For more information about purging a datastore, see How to Purge the Datastore. in the Using the Oracle GoldenGate Microservices Architecture.

From Oracle GoldenGate 12.3.0.1 onward, all operations related to the datastore have been removed and are taken care of by the Performance Metrics server. To know more, see Monitoring Performance.
