Hello,

Can you give me some tips or considerations to automate tablespace administration?

I know that Enterprise Manager can implement thresholds(critical and warnings) about free space and occupied space, but this is relative to current size of datafiles but do not take into consideration max extents.

If you have some advice or scipts i could implement to monitor this i would thank a lot.

Thanks in advance.

>>but do not take into consideration max extents
Why would you monitor that? In 10g? Are you still using dictionary managed tablespaces?
Just search the forum. There are many versions available.

Excuse me please, i didn't mean maxextents but maxsize, i think i did not explain correctly, in fact i'm usng locally managed tablespaces, but what i really need is an automatic way to know if a tablespace is running out of free space, but taken into consideration total space (maxsize) it can grow on the filesystem, not only the size that is currently extended.

The file can only grow if you have enabled autoextend on, which is a bad idea.
Without autoextend on, you can just monitor the space used within the tablespace and if it reaches a certain threshold you get alerted and do something .
If you have autoextend on, you may run the issue of eating up the diskspace and need to get the System admins to get involved to extend the disk.
Either way, you need to do monitoring. So, it is better to go without autoextend on.
If you still want to go with, all it needs is a simple shell script.
Do a
df -h

and filter out what you want and do whatever you want with it.
