You pick up little funny things in the day to day with Oracle.
Like this one when you try to drop a tablespace with a queue table in it:
drop tablespace MY_TSPACE including contents * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 1 ORA-24005: Inappropriate utilities used to perform DDL on AQ table SCOTT.QUEUE_TABLE
You would think that since you’ve asked to drop everything, that well…everything could be dropped, but no🙂
The solution here is to use DBMS_AQADM.DROP_QUEUE_TABLE (with force=true if necessary) to clean it out, and the re-issue your command.
