^Z, which suspends a process without so much as a by-your-leave and without the process even being notified, is a very bad thing to do to a GT.M process, akin to a kill -KILL (kill -9) or kill -STOP.
If you inadvertently suspend a process, send it a CONT signal kill -CONT to resume operation, or an fg to resume it in the foreground (or at least a bg to resume it in the background). There are multiple ways to prevent yourself from inadvertently suspending a process, which have been discussed on this list. My favorite is to simply unlink ^Z from suspend, with a stty susp \000 before executing a GT.M process. If you inadvertently suspend a process and then reboot without resuming it, or if you kill the process with a -9, as soon as practicable, you should run a mupip integ on the database. Under normal conditions, if you want to terminate a GT.M process from the outside, use mupip stop (which is equivalent to kill -TERM). -- Bhaskar On Sat, 2004-12-25 at 03:12, Chris Richardson wrote: > Kevin; > > Is the task accumulating and CPU time? > Do a; > >ps -ael > > at the Linux prompt to see if there is any change in the resources > consumed. > > I suspect that the task is just a zombie which should go away if you > reboot, or is just taking up a small bit of memory. > > See if you can do a mupip rundown.
