/tmp filesystem full

[Andy Wodfer]

Hi,
I have about 500MB in my /tmp and it seems to be too small when the
periodic LOCATE script runs every week.

What's the best way to increase the size of /tmp ? Could I simply remove it
and create a symbolic link ln -s to say /usr/tmp instead (where I have
several hundred GBs free)?

PS! This is on a live server and I would like to keep downtime and problems
to a minimum. :-)

Cheers,
Andy
