From 12c on wards we don’t need to run Patching post installation scripts postinstall.sql & @catbundle.sql psu apply and validate log files manually .. All we need to do is just run datapatch after applying patch. ****************************** *********************** In 11G After applying patch we need to run like following order .. postinstall.sql => for OJVM in upgrade mode @catbundle.sql psu apply => for PSU in normal startup mode ****************************** *********************** But from 12c datapatch will take care of post scripts work. ./datapatch –verbose Please see log for datapatch.
