RE: [Q] way to shrink temporary tablespace ??

Replies:
That is why I like to set a maxsize on my temp tablespaces to a reasonable limit. Then, if user's queries fail with ora-1652, it's probably because they're running poorly written queries with unselective predicates, cartesian joins, etc. This helps me identify when they are running those and correct them rather than just letting them eat up system resources and grow the temp tablespace to a ridiculous size.

Brandon

I had the same problem, the temproary tablespace datafile had grown to
32Gb. This was worrying as the database contained less than 3Gb of
actual data. We eventually concluded (after looking at the sorts of
queries that were popping up in v$sql) that a lot of users were
running very unselective queries with sorts in them that meant that
virtually the entire database was being sorted repeatedly in many
rowsets.
