FRM-40735: When validate item triger raised unhandled exception ORA-04063

For the above error mentioned I have almost referred all the documents on metalink and have followed the solution. But still the error remains. Could someone help me out to get rid of this error. Below I have pasted the steps that I followed to solve this problem:

The scripts must be run in the following order:

1. utlirp.sql

2. utlrp.sql


Requirement is to run these scripts as     sqlplus '/ as sysdba'

and in 'startup upgrade' mode ( example:   SQL> startup upgrade )

Once completed, please check invalid objects within your instance
and verify that package PER_PEOPLE4_PKG is no longer invalid.
