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

It will be increasing because you have a need for temporary storage space, possibly due to a cartesian product or a large sort operation.

The dynamic performance view V$TEMPSEG_USAGE will help diagnose the cause.
