We have RacOne node environments on both primary and standby sides as below.We need to apply the latest 11203 PSU patches to both GI and the DB Homes. What is the ideal way to proceed since the clusterA is primary for few databases and standby for few databases. Since we have to run the catbundle.sql script on primary once we apply the PSU patch. Do we need to apply the patches to both Side A and Side B at the same time? Thanks in advance!
Side A(cluster) Side B(cluster)
Primary db1 Standby db1
Primary db3 Standby db3
Standby db2 Primary db2
Standby db4 Primary db4
