Sun Cluster Data Service for MySQL Guide for Solaris OS

Debug Sun Cluster HA for MySQL

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

ProcedureHow to Activate Debugging for Sun Cluster HA for MySQL

  1. Determine whether you are in a global zone or in an HA container configuration.

    If your operating system is Solaris 10 and your MySQL resource is dependent on a Solaris Container boot component resource, you are in an HA container configuration. In any other case, especially on a Solaris 9 system , you are in a global zone configuration.

  2. Determine whether debugging for Sun Cluster HA for MySQL is active.


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

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

  3. If debugging is inactive, edit the /etc/syslog.conf file in the appropriate zone to change daemon.notice to daemon.debug.

  4. Confirm that debugging for Sun Cluster HA for MySQL is active.

    If debugging is active, daemon.debug is set in the file /etc/syslog.conf.


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

  5. Restart the syslogd daemon in the appropriate zone.

    • If your operating system is Solaris 9, type:


      # pkill -1 syslogd

    • If your operating system is Solaris 10, type:


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

  6. Edit the /opt/SUNWsczone/sczbt/etc/config file to change the DEBUG= variable according to one of the examples:

    • DEBUG=ALL

    • DEBUG=resource name

    • DEBUG=resource name,resource name, ...

    Note –

    To deactivate debugging, repeat step 1 to 6, changing daemon.debug to daemon.notice and changing the DEBUG variable to DEBUG=.
