Hello guys,
how do I apply PSU on Oracle RAC database without any downtime? (patch only database, not clusterware).
Lets say I have 2 node RAC on separate hosts with separate oracle/grid homes (resources not shared). What are the steps to avoid downtime? I simply apply latest OPatch onto oracle/grid homes, then generate ocm.rsp file from oracle user and simply execute as root: opatch auto /patch/path/ -oh oracle_home -ocmrf /path/ocm.rsp and it will do everything for me on that node? then relocate service onto patched node and do the same steps on another node? Is that it and there will be no service interuption? Thanks!
