Why wait (S-S contention) for 20 hours?

edited Nov 9, 2009 5:38AM in Database Tuning (MOSC) 2 commentsAnswered
I tried to reduce a tablespace temp1 while job statistics(dbms_stats.gather_database_stats_job_proc) was running. here is the steps i followed :
- Create a new temp2
- Switch the default temp  tablespace to temp2
- drop temp1 but i can't drop it because it was in use
- Switch the default temp  tablespace back to temp1
- drop temp2(successful)
After this, the job statistics was in wait (S-S contention) for 20 hours.
 
Any help on this!!?

Howdy, Stranger!
