Problem Automatic Workload Repository after upgrage to 10.1.0.4.0

Question

Hello everybody,
We upgraded last week a database 10g from release 10.1.0.3.0 to 10.1.0.4.0.
Since this upgrade, the AWR doesn't create any snapshot anymore but the process MMON is still living.
I tried to modify the interval of creation (reduce from 1H to 30min) of the snapshot using EM. When I execute the command I receive the following error statement:
Please correct the following error:ORA-13516: SWRF Operation failed: CATPROC not valid ORA-06512: at "SYS.DBMS_WORKLOAD_REPOSITORY", line 83 ORA-06512: at line 1
Should I re-execute some script(s) from .../RDBMS/ADMIN to fix it?
Thank a lot in advance for your support to solve this issue.

Hopefully I could find a post on the Oracle Forum to fix my issue.
I did the following operations:
1) SHUTDOWN IMMEDIATE;
2) STARTUP UPGRADE;
3) SQLPLUS / AS SYSDBA
4) @<Oracle_home>/RDBMS/ADMIN/CATPATCH.SQL
5) When the script completed check that no errors occured.
6) SHUTDOWN IMMEDIATE
7) RESTART
After this the Automatic Workload Repository could execute normally the snapshots and I was able for exemple to modify the frequence of the snapshots creation.
I only don't understand why I had to execute this sql script to get in running. Should this script not be a part of execution of the upgrade 10.1.0.3.0 to 10.1.0.4.0 ?
