Debugging HA for MySQL Cluster

Each HA for MySQL Cluster component has a file named config that enables you to activate debugging for MySQL Cluster resources. This file is in the /opt/SUNWscmys/component/etc directory.

How to Activate Debugging for HA for MySQL Cluster

1. Determine whether debugging for HA for MySQL Cluster is active.

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

2. Determine whether debugging is active.
   • If daemon.debug appears in the /etc/syslog.conf file of the global zone or the zone cluster's zone, debugging is active.

     You do not need to continue with this procedure.

   • If daemon.notice appears in the /etc/syslog.conf file of the appropriate zone, debugging is inactive.

     Continue with the rest of this procedure.

3. In the /etc/syslog.conf file in the appropriate zone, change daemon.notice to daemon.debug.
4. Restart the syslogd daemon in the appropriate zone.

    # svcadm refresh svc:/system/system-log:default

5. Edit the appropriate /opt/SUNWscmys/component-name/etc/config file to add a value to the DEBUG= parameter:

   The value of the component-name can be ndb_mgmd, ndbd, or ndbd_shutdown.

   • To debug all resources, use DEBUG=ALL

   • To debug specific resources, use DEBUG=resource-name, resource-name
