Do not upgrade 11.2.0.1 to 11.2.0.1

If you do run @?/rdbms/admin/catupgrd for an 11.2.0.1 Oracle Home on a 11.2.0.1, you may later realize some objects are missing (probably related to deferred segment creation).

SQL> delete from t1
2 where id in (
3 select ca.id from ca, p
4 where p.no_form like '%02.98'
5 and p.id = ca.prod_id
6 );
delete from t1
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [kkpo_rcinfo_defstg:objnotfound],
[56480], [], [], [], [], [], [], [], [], [], []

The workaround on metalink is amazing :

  • Do not run catupgrd in 11.2.0.1 against a database that is already at 11.2.0.1

Well, the only solution is to restore your database ! How painful 🙁
