How to shrink temp tablespace in oracle?

Question

How can we shrink temp tablespace in oracle? And why it is increasing so much like upto 25 GB since there is only one schema in the database for the application and data tab

Answer 1

I don't bother with dropping the alternate temp in case i need to reclaim storage again in the future...

1. from temp group set default to stand-alone temp
2. wait awhile, then resize members of temp group
3. set default back to temp group
4. wait awhile, resize stand alone temp. there's no rush to do the last step
