Killing a process....

Chris Fadrowski — Thu, 12 Feb 2009 15:29:16 GMT

I have an Oracle process (actually 3 of them) that i am trying to kill due to an inactive DB. I tried the "Kill" and "kill -9" etc but the processes won't die.

Is there any other commands i can try and why is 'kill" not working as it's supposed to?

reboot my only option?

If the process will not die after a 'kill -9' then the process is waiting on something, likely an I/O operation, to complete. If that operation never completes then the process will never die.

It is not that "kill" isn't working as it should. The issue is that the process is not in a state to acknowledge the kill signal sent to it.

makes sense. I guess my only course is reboot?

Unfortunately, unless you can figure out a way to satisfy whatever the process is waiting on, a reboot is the only option.

Hi Chris

Before reboot you can try with fuser if the process really waiting for some I/O

#fuser -ku -c

I assume these aren't zombies?

Do you really care you can't kill them? Are they holding resources, the SGA?

It isn't kill that's broken but the design of Unix that doesn't allow root to abort I/Os.
