Debug Sun Cluster HA for WebSphere MQ

How to turn on debug for Sun Cluster HA for WebSphere MQ

Sun Cluster HA for WebSphere MQ can be used by multiple WebSphere MQ instances. It is possible to turn debug on for all WebSphere MQ instances or a particular WebSphere MQ instance.

A config file exists under /opt/SUNWscmqs/xxx/etc, where xxx can be mgr (Queue Manager), chi (Channel Initiator), csv (Command Server), lsr (Listener) and trm (Trigger Monitor).

These files allow you to turn on debug for all WebSphere MQ instances or for a specific WebSphere MQ instance on a particular node or zone within the cluster. If you require debug to be turned on for Sun Cluster HA for WebSphere MQ across the whole cluster, repeat this step on all nodes within the cluster.

Edit /etc/syslog.conf and change daemon.notice to daemon.debug.

# grep daemon /etc/syslog.conf
*.err;kern.debug;daemon.notice;mail.crit        /var/adm/messages
*.alert;kern.err;daemon.err                     operator
#

Change the daemon.notice to daemon.debug and restart syslogd. Note that the output below, from grep daemon /etc/syslog.conf, shows that daemon.debug has been set.

# grep daemon /etc/syslog.conf
*.err;kern.debug;daemon.debug;mail.crit        /var/adm/messages
*.alert;kern.err;daemon.err                    operator

Restart the syslog daemon.

If running Solaris 9
# pkill -1 syslogd

If running Solaris 10

# svcadm disable system-log
# svcadm enable system-log

Edit /opt/SUNWscmqs/xxx/etc/config.

Perform this step for each component that requires debug output, on each node of Sun Cluster as required.

Edit /opt/SUNWscmqs/xxx/etc/config and change DEBUG= to DEBUG=ALL or DEBUG=resource.

# cat /opt/SUNWscmqs/mgr/etc/config

#
##ident   "@(#)config 1.2     06/03/08 SMI"
#
# Usage:
#       DEBUG=<RESOURCE_NAME> or ALL
#
DEBUG=ALL

Note –

To turn off debug, reverse the steps above.
