You can change the database processes back to 20 with:

renice -n 0 ...

How do you start the databases? The database processes will inherit the nice value of the job that starts it.

John

George,

Interestingly it has been happening here. We opened call with HP and oracle and they couldn't find the reason. The workaround we are doing is to relink the oracle executables. It seems to fix the problem. Try it out.

Hi,

Another option: You can use SAM to change the nice priority of any process. Under Process Management, it will list you all processes running on the system and you can change the nice value if you want.

If you want to change the priority, use 'rtprio' command.

HI
Check the shell env parameter (bgnice)
#set -o
if "bgnice" is on, any process started in that shell will have pri as 24.
Turn the bgnice with "#set +o bgnice" and all processes started in that shell will have pri. 20.

Thanks.
Prashant.
