Recompiling All Oracle Invalid Objects.

This is a very simple request for help.
I know there is a script to recompile all invalid objects in Oracle.

Oracle 11g

Looked under --/RDMS/------ but cannot find it.
This would be one Oracle provided.

Anybody know the name?
Appreciate the help.

ignore my prior reply!

I think you are looking for %ORACLE_HOME%/rdbms/admin/utlrp.sql

Thank you.
Appreciate the help.
