ARSSOCKD crashes in V9.0.0.6

[Anand]

Hi All

We are running CMOD 9.0.0.6 with DB2 9.7 and TSM 6.3.5 all hosted in same AIX server.

ARSSOCKD process went down without any error message. DB2 and TSM had no issue during the time. After checking the AIX alog, we noticed that below error message thrown from TSM just before the crash. There is no error in syslog also.

Also whether the below ulimit values any reason for the arssockd crash?

time(seconds)        unlimited
file(blocks)              unlimited
data(kbytes)           unlimited

memory(kbytes)     unlimited
coredump(blocks)     0
nofiles(descriptors) 2000

Anyone faced similar issue before? Kindly help.

On z/OS - and I know that isn't the environment here, but - when ARSSOCKD loses TCP/IP connectivity to DB2 for too long a period of time ARSSOCKD will abend.

What happens is because ARSSOCKD abends people think there's a CMOD problem, but there really isn't.  It's a TCP/IP problem and ARSSOCKD is the victime.

This looks like a configuration error.  Check your dsm.sys and dsm.opt files for bad values, and it's always best to put fully qualified hostnames in configuration files.

A fully qualified domain name looks like:

Code: [Select]

tsm-cmod.dc2.example.com
rather than:

Code: [Select]

tsm-cmod
