RE: temp tablespace blow up

A tempfile is not just another datafile. For one thing, it's initially sparse. For another, a tempfile tablespace does not need to be backed up, and at recovery time, is simply (and quickly) recreated.  

For a good summary of the different possible types of temporary tablespaces, see this URL:

Yes, it's dated, but it's still accurate.

Just a dbfile like the others.  

Just curious, which Oracle release you run? 8i?

Asunto: Re: temp tablespace blow up  

just ran an update that had some stupid huge joins and couldn't allocate anymore extents because the 4gb of datafiles were too small. So my update errored. then, no problem still, just that my temp tablespace had an enormous amount of extents. So, i dropped it when users were off and recreated it as TEMPORARY. I've been reading about temporary tablespaces:

CREATE TEMPORARY TABLESPACE blah TEMPFILE '/d01/oradata/PROD/blah.dbf' size 1000M;
