There can be scenarios where you will get below error while running utlrpl.sql

SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
 SELECT dbms_registry_sys.time_stamp('utlrp_bgn') as timestamp from dual
                                                                   *
 ERROR at line 1:
 ORA-04045: errors during recompilation/revalidation of SYS.DBMS_REGISTRY_SYS
 ORA-01031: insufficient privileges

work around solution for this problem:

SQL> ALTER SYSTEM SET "_system_trig_enabled" = FALSE scope=both;
 System altered.

Now run utlrp.sql again. It will work fine this time.
