We are seeing extremely high temp tablespace read/writes (on a ESTAT/BSTAT) report. I'm trying to figure out what process is causing this. Noticed a few tables (V$SORT_USAGE, V$SESSTAT, etc...) but they are empty. Does anyone know what process populates these tables? or does anyone have any suggestions on how to gets detailed stats on the temp tablespaces?
Thanks.

First you should use Statspack instead of bstat/estat you will get much more and useful information.
Then v$ views are dynamic ones so show you what happpens now but if you follow these views (v$sort_usage and v$session, sort and direct reads/wirtes statistics) you should be able to see which sessions use temp tablespace then which SQL statements.

Michel
