A Question about catcpu.sql file related to Oracle patching

Dear Sir,

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.
Pradeep.

(1). What is this file and what is the purpose of this?

Catcpu.sql inturn calls a script called catbundle.sql which is located under $ORACLE_HOME/rdbms/admin

This script will load sql files in database by looking in bundledata_CPU.xml for file information for particular patch. It will be creating a dynamic apply sql file and run it.



(2). With each and every Oracle CPU patch, Does Oracle send this file?

--Yes

(3). After apply Oracle CPU patch, should  we run this file definitly? if not what will be happened?

Its simple, some of the data which is a part of the the patching activity doesn't get applied to db, due to which the patch may not work properly...

Same question has been asked in numerous forums in the past years, just google it, here are some of the references to those sites
