Hi

In one of my clients I have multiple dsmcad services running!. Any idea where to start looking for info?

dsm.sys is posted below!!

[tsm@lf0hrwb01p bin]$ ps -ef | grep dsm
tsm 1738 31948 0 08:31 pts/8 00:00:00 grep dsm

Well, any harm to kill them?

Just kill and see if they comes back... or have you already tried this?
 
yeah killed them

but when i satrt it all comes up again!!
 
I was tired troubleshooting and upgraded the linux client from 5.4.1.0 to 5.4.3.0 hoping it would resolve this

to my dismay the issue is reoccuring again :( :( :(


what could cause multiple cad services running ?

[root@lf0hrwb01p bin]# ps -ef | grep dsm
root 21139 29761 0 13:17 pts/8 00:00:00 grep dsm
[root@lf0hrwb01p bin]# ./dsmcad
[root@lf0hrwb01p bin]# ps -ef | grep dsm
root 21163 1 0 13:17 ? 00:00:00 ./dsmcad
root 21164 21163 0 13:17 ? 00:00:00 ./dsmcad
root 21165 21164 0 13:17 ? 00:00:00 ./dsmcad
root 21166 21164 0 13:17 ? 00:00:00 ./dsmcad
root 21167 21164 0 13:17 ? 00:00:00 ./dsmcad
root 21169 29761 0 13:17 pts/8 00:00:00 grep dsm
 
Hi,

check /etc/inittab for "respawn" lines.
It may make sense to run multiple dsmcad services .... is it your setup or you got this system already configured?

Harry
 
The initab goes like this

1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6
# Run xdm in runlevel 5
x:5:respawn:/etc/X11/prefdm -nodaemon
cad::eek:nce:/opt/tivoli/tsm/client/ba/bin/dsmcad >/dev/null 2>&1
# TSM Webclient


I got this system already configured!!
 
Hi,

looking at the output you provided earlier ...
seems there is one "parent" dsmcad process (PID 21163) started by init (PID 1). The other processes seem to be children/grandchildren of this process. So one "dsmcad" spawns another.
Does that happen immediately after starting the dsmcad? Without any incoming connection which may do this? Anything in dsierror.log, dsmerror.log?

Harry
 
yes multiple dsmcad process are satrted the very second I give ./dsmcad.

More over the initab settings are the same for couple of my other servers which have only 1 dsmcad running and tehre are servers with multiple cad similar to the above output!!!

and the errorlog has

01/31/11 01:04:36 ANS1512E Scheduled event 'DAILY_INCR' failed. Return code = 134.

Hi,

stop the dsmcad (killall -9 dsmcad), delete (move away) your logs and start the dsmcad. Then show us the logs (so we have the current info).
About ANS1501E - how the permissions are set?
Easiest way you can do is to uninstall the client, save the config files, DELETE the /opt/tivoli/tsm/client/* and install it from fresh ...
This should solve "hidden" permission problems ...

this is only error I have after moving the error logs, i cant relate this error with multiple dsmcads though!!!
 
Hi,

weird - getting out of ideas here - what version of linux and TSM client do you use? What problem does this situation cause?

Harry
 
Check whether all the dsmcad process are local to that server or being executed from other server. (globa,local).

ps -aefZ|grep dsm
 
Hi

the services are running on the same server.

It dint cause any issue .I am just wondering why the malfunction?

More over i see multiple updates for the same schedule in the act log of the srever which is approx equal the number of dsmcad services

Sorry far the delayed response was into multiple things for the last few weeks.

and many many thanks for your suggestions!
 
Pheww... stubborn...

Ok, shoot in the dark.. cancel all dsmcad and then run dsmcad in background...

Hi Guys,

many thanks to every one for helping me!

GOt the root cause nailed. Thanks to IBM support for once!!

LD_ASSUME_KERNEL= dsmcad'

the above command fixed the issue

Comments from IBM are as below


development have the following comments for you:
**************************************************************
in the dsminfo.txt I have found a variable LD_ASSUME_KERNEL=2.4.19.
With LD_ASSUME_KERNEL you can
specify the kernel version (in our case 2.4.19) and get the changed POSIX thread implementation for
the process witch run in it. With such parameter(LD_ASSUME_KERNEL=2.4.19) threads will be showed
like processes with ps command.
This means that blue processes are threads only!
[root@lf0hrwb01p ~]# ps -ef|grep dsm
root 29078 1 0 10:23 ? 00:00:00 dsmcad
root 29079 29078 0 10:23 ? 00:00:00 dsmcad
root 29080 29079 0 10:23 ? 00:00:00 dsmcad
root 29081 29079 0 10:23 ? 00:00:00 dsmcad
root 29082 29079 0 10:23 ? 00:00:00 dsmcad
root 29091 28980 0 10:23 pts/4 00:00:00 grep dsm
If it is a problem for customer and he need to use LD_ASSUME_KERNEL for his own purposes, he can
try the next variant.
Run 'LD_ASSUME_KERNEL= dsmcad' instead of 'dsmcad' in his scripts. This command will run dsmcad in its own environment.
