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. An example of a client that requests data from Object
Manager is Serviceguard Manager.
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
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 is found in
the package’s control script log. This log provides the history of the
operation of the package control script. It is found in the same directory
as the control script itself. This log documents all package run and halt
activities. If you have written a separate run and halt script for a
package, each script will have its own log. Refer to “Understanding the
Location of Serviceguard Files” on page 122 for references to $SGCONF.
