Fixing the "kkjcre1p: unable to spawn jobq slave process" error

Probelm Description:
I found this error in database alert log file

Process J000 died, see its trace file
Wed Oct 27 12:56:39 2010
kkjcre1p: unable to spawn jobq slave process
Process J000 died, see its trace file

kkjcre1p: unable to spawn jobq slave process
Process J000 died, see its trace file

kkjcre1p: unable to spawn jobq slave process

the database hangs and no further connection are allowed to the database.

Cause:
The failure to spawn error almost always indicates a hardware resource shortage, often RAM or a lack of process memory.

Solution:
1 - This can be from the "processes" parameter being set too low,increase the valuse for this parameter and restart the database to take effect.
2 - check that job_queue_processes parameter it is not set to 0.
3 - Check your server stats, you may have run out of available server RAM resources.
