GoldenGate upgrades/patching on RAC

in GoldenGate, Streams and Distributed Database (MOSC) 2 commentsAnswered ✓

We are rolling out goldenGate on 2 node RAC environment, replicating 1 way between 2 databases on the same RAC. The thought is steady state will run source extract on node1 and target apply on node2. Plan is to use Microservices Architecture not Classical.

The recommendation is local install (so 4 homes node1source, node1target, node2source, node2target) and local trail files (so 4 repositories node1sourcetrail, node1targettrail, node2sourcetrail,node2targettrail)

Trying to flesh out the tradeoffs of using shared mounts for the installs ( so sourcehome,targethome) and trail file repositories (sourcetrail, targettrail).

The installs on shared I can see would cause a longer outage on patching. Stop, apply opatch, restart as opposed to failover, patch idle home, failback.
