Debug Sun Cluster HA for Oracle Application Server

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

Each Oracle Application Server component has a DEBUG file in /opt/SUNWsc9ias/etc.

This files allows you to turn on debug for all Oracle Application Server resources or for a specific Oracle Application Server resource on a particular node with Sun Cluster. If you require debug to be turned on for Sun Cluster HA for Oracle Application Server across the whole Sun Cluster, repeat this step on all nodes within Sun Cluster.

How to turn on debug for Sun Cluster HA for Oracle Application Server

  1. 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
#
