Hi all
Made some updates to the db_cpu script. It can now cope with the situation where there are no databases running. Previously, it would simply exit if it found nothing. Now it reports it, and can trigger an alert if you configure it so.
Regards Vernon

Hi all
I have updated this script to fix Andrey's reported bug. I have also added an option to use sar for calculating %Idle, after Nick reminded me that top is not part of a standard install.

A good catch, and something I didn't consider. All our databases instances have very different names, so the scenario you describe just never occurred to me. I will have a look at fixing this one when I get back to the office on Tuesday. (Monday is a public holiday here) However, if anybody wants to suggest a fix, or even update the code, go for it.
Regards Vernon

Good news.
Had reviewed the script. There may be one problem in that lines:
for PROC in $(ps -efa | grep $DB | awk '{ print $2 }')
You do just grep, but imagine there may be instances like: MYDB MYDB1 MYDB12 or NOMYDB So it will count MYDB numbers for MYDB1, MYDB12 and NOMYDB too
We should make grepping more intelligent, because oracle processes may be listed like: ora_j000_MYDB oracleMYDB (LOCAL=NO) ora_ckpt_MYDB and so on
