Reviewing Object Manager Log Files
The Serviceguard Object Manager daemon cmomd logs messages to the
file /usr/local/cmom/cmomd.log on Red Hat and
/var/log/cmmomcmomd.log on SUSE. You can review these messages
using the cmreadlog command, for example:
/usr/local/cmom/bin/cmreadlog /usr/local/cmom/log/cmomd.log
Messages from cmomd include information about the processes that
request data from the Object Manager, including type of data,
timestamp, etc.
Reviewing Configuration Files
Review the following ASCII configuration files:
• Cluster configuration file.
• Package configuration files.
Ensure that the files are complete and correct according to your
configuration planning worksheets.
Reviewing the Package Control Script
For legacy packages, ensure that the package control script is found on
all nodes where the package can run and that the file is identical on all
nodes. Ensure that the script is executable on all nodes. Ensure that the
name of the control script appears in the package configuration file, and
ensure that all services named in the package configuration file also
appear in the package control script.
Information about the starting and halting of each package can be found
in the package’s control script log. This log provides the history of the
operation of the package, including all package run and halt activities.
The location of the file is determined by the script_log_file
parameter (see page 204) in the package configuration file. If you have
written a separate run and halt script for a legacy package, each script
will have its own log.
