QUESTION POSED ON: 24 July 2006
Hi, I'm a beginner who has to solve an inherited trouble on a Suse-Linux machine with Oracle Database 10g. The problem is that the mounting points where there are applications and database are 100% used. The system doesn't raise any warning yet but I think that it is nearly exploding. This is a machine still deployed in production, and there is no more space to extend partitions on the HDU. After some googling I realized that maybe the problem is due to the temporary space used for long queries (that I can't analize now). How can I solve this problem? Thanks.

Tablespace situation from Oracle Enterprise Manager:

EXPERT RESPONSE
The fact that your disk volumes are at or near capacity should not have a major effect on Oracle performance. If any tablespace (including TEMP) needs more space and such space is not available, you will see an error. If you are experiencing a specific performance problem, please post the details.
