Linux SUSE - start/stop script problem (using PIDs)

[John22439]

Hello all!

I'm having some difficulty getting this script (from the Novell website) to kill ONLY the DSMCAD that I'm targeting.

I have 2 scripts, one is for the GLOBAL file system (actually a shared file system) and one for the LOCAL node.

Script 1: S99Tivoli_Local
Script 2: S99Tivoli_Global

I have 2 CADs running:

DSMCAD_BIN=/opt/tivoli/tsm/client/ba/bin/dsmcad (the LOCAL script targets this one)
DSMCAD_BIN=/usr/bin/dsmcad (the GLOBAL script targets this one)

The start up scripts work and both have individual PIDs.

I've altered both scripts to point to individual PID files... So that there is no conflict. (not sure if this is correct)

DSMCAD_PIDFILE=/var/run/dsmcad.pid
DSMCAD2_PIDFILE=/var/run/dsmcad2.pid

When I have a problem with one of the CADs, I would like to target that CAD for a stop and start. When I run this script, it does not make use of the "PID" ... but kills ALL the DSMCADs.

If you have any suggestions, or need more info, please post.

Thanks,
j

Sooo....

I guess this one is "un-fixable"....

The problem as I see it is identifying which dsmcad instance to shutdown unless you have some unique pointers as to which is local or global.

One way around this, and maybe a more positive way of doing it, is to use the dsmc service rather than the dsmcad service to start either the local or global TSM instance.

Hi,
killproc seems to be ignoring the PID (-p).

Try this to confirm: start your two dsmcad, then on the terminal run: "killproc -v -p pid_of_first_dsmcad /opt/tivoli/tsm/client/ba/bin/dsmcad"

If it kills both, you migth need a package patch for killproc. Or you can use kill instead of killproc.
