Hi thanks for the response. Quick question, in the 3rd document it says:
"Oracle Clusterware and Oracle ASM upgrades are always out-of-place upgrades. With 11g Release 2 (11.2), you cannot perform an in-place upgrade of Oracle Clusterware and Oracle ASM to existing homes."
This mean that I need to install the whole 18.104.22.168 version in another ORACLE_HOME instead of apply the patch to the 22.214.171.124 ORACLE_HOME?
