Can I drop a tempfile while my DB is up and running?

Hi ,
We have many databases with some running on windows boxes and some running on OEL boxes with 10g an 11g versions. A week ago I found that all the tempfiles of temporary tablespace in all databases are autoextensible .All are above 10GB. So i made them autoextend off. Today I got ORA- 01652 error . As a temporary solution I brought back all the tempfile to autoextend on for now.

         Can I add a tempfile to temporary tablespace and drop the old tempfile? Will it effect any on going transactions (because all are production databases) ? I know that sorts will be done in temporary tablespace, but what is actually stored in them to make them grow above 10gb?

Howdy, Stranger!
