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"
