performance tuning tsm server
Servers running on redhat enterprise 6.1 and 6.5. Trying to set open files, max processes, etc for the dsmserv process. Tried using /etc/security/limits.conf, but no help. Looking in /proc/process-id/limits Open files is 4096. However, set at 8192 for soft and 10240 for hard in /etc/security/limits.conf. Any idea where the 4096 is coming from?
Re: performance tuning tsm server
Hello,
I added the following two lines in the tsm startup script. the -n 8192 in
the startup script will start the process using the higher count number.
more /etc/init.d/tsminst1
start() {
# make sure that the server CAN create a core dump in the event of an error
# NAM - 16082014 - Added Ulimit 8192 for open files and -c unlimited for
core dump
ulimit -c unlimited
ulimit -n 8192
echo -n Starting $prog instance $instance ...
#if we're already running, say so
Hope that helps,
-Nick

Re: performance tuning tsm server
Yep, we do the same thing. Note that /etc/security is only used by PAM, so
processes that don't descend from a PAM-managed login won't be affected by
it. This makes for an interesting problem where you will get different
limits for dsmserv if it's started during the system's boot process vs
started manually by a login shell, since the login shell will have PAM
limits on it. For this reason, you should always set the ulimit values you
need in the init script.

Re: performance tuning tsm server
If you search the ADSM-L archives, you will see we went through this a while ago. The startup script (for us tsminst1_dsmserv.rc) contains ulimit statements that sets them to much higher values - *ulimit -n 65536* and *ulimit -c unlimited*) . Second, when we upgraded to 6.3.5, IBM changed the startup script which further effects this.

Re: performance tuning tsm server
Adding those lines worked.
Can one change the file /proc/pid/limits and change the limit for the running
dsmserv process?
I doubt it but thought I'd ask.
