Use the information in this section to understand how to turn on debug for Sun Cluster HA for MySQL.
Sun Cluster HA for MySQL can be used by multiple MySQL instances. However, it is possible to turn on debug for all MySQL instances or for a particular MySQL instance.
Each MySQL component has a DEBUG file under /opt/SUNWscmys/etc, where xxx is a three character abbreviation for the respective MySQL component.
These files allow you to turn on debug for all MySQL instances or for a specific MySQL instance on a particular node with Sun Cluster. If you require debug to be turned on for Sun Cluster HA for MySQL across the whole Sun Cluster, you will need to repeat this step on all nodes within Sun Cluster.
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. The output below, from the command 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 # # pkill -1 syslogd # |
Edit /opt/SUNWscmys/etc/config and change DEBUG= to DEBUG=ALL or DEBUG=resource
# cat /opt/SUNWscmys/etc/config # # Copyright 2003 Sun Microsystems, Inc. All rights reserved. # Use is subject to license terms. # # Usage: # DEBUG=<RESOURCE_NAME> or ALL # DEBUG=ALL # |
