How to turn debug on forSun Cluster HA for WebSphere MQ Integrator

Use the information in this section to understand how to turn on debug for Sun Cluster HA for WebSphere MQ Integrator.

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

Each WebSphere MQ Integrator component has a DEBUG file under /opt/SUNWscmqi/xxx/etc, where xxx is a three character abbreviation for the respective WebSphere MQ Integrator component.

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

  1. Edit /etc/syslog.conf

    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 the command grep daemon /etc/syslog.conf, shows that daemon.debug has now been set.


    # grep daemon /etc/syslog.conf
    *.err;kern.debug;daemon.debug;mail.crit        /var/adm/messages
    *.alert;kern.err;daemon.err                    operator
    #
    # pkill -1 syslogd
    #
  2. Edit /opt/SUNWscmqi/sib/etc/config

    Perform this step for the Broker component (sib), then repeat for the optional UserNameServer (siu) that requires debug output, on each node of Sun Cluster as required.

    Edit /opt/SUNWscmqi/sib/etc/config and change DEBUG= to DEBUG=ALL or DEBUG=resource


    # cat /opt/SUNWscmqi/sib/etc/config

    #
    # Usage:
    #       DEBUG=<RESOURCE_NAME> or ALL
    #
    DEBUG=ALL
    #

    Note –

    To turn off debug, simply reverse the steps above.
