Scenario 1:
Patching falied dure to certain reasons on both both the node
JUST REPLACE THE OLD BINARIES WITH NEWLY CREATED BINARIES.
Scenario 2:
when root102.sh was executed in any node of the RAC and root102.sh failed on rest of the nodes then.
you have remove the node from the cluster and add it again.
which node to remove?
where root102.sh executed successfully because u want to go back to old setup.
