The following steps have been performed successfully:
- Create a new temporary tablespace
- Declare as the new default temp
- Make sure that no users have the old temp as their default
Now trying to drop the old temporary tablespace, the session hangs.
Analyzing the problem shows the following:
- Tracing the session using 10046 shows that the session is waiting for event "enq: TS - contention'"
- System state dump shows that the session is blocked by SMON
- SMON is waiting for event "SMON TIMER"
