While I am reading README files of Oracle CPU patches, I saw every time after patched DB, we have to run a file called catcpu.sql
My questions here are,
(1). What is this file and what is the purpose of this?
(2). With each and every Oracle CPU patch, Does Oracle send this file?
(3). After apply Oracle CPU patch, should we run this file definitly? if not what will be happened?
Thank You in advance.
