Oracle: Patch RAC

If you don't specify -local, opatch is going to patch all nodes. As a DBA, you should test on one node first, then roll out the patch on all other nodes.

If you have multiple Grid Infrastructure Home or Oracle Home, you can specify which one to patch:
$ opatch apply -local -oh /oracle/apps/grid/11.2.0.3



If only one of them and you are using specified opatch for each home, you can run opatch as below:
$ opatch apply -local

Then roll out the patch on individual node.



$ opatch apply -remote_nodes db02


 Roll back specified patch

$  opatch rollback -id 15983996
