Serviceguard Extension for SAP on Linux:
cmcluster.config
The Linux distribution of Serviceguard uses a special file,
/etc/cmcluster.config, to define the locations for configuration and
log files within the Linux file system. These paths differ depending on
the Linux distribution used.
In this document, references to /etc/cmcluster.config can be replaced
by the definition of the variable that is found in this file
/etc/cmcluster.config. The default values are:
• For SUSE Linux - SGCONF=/opt/cmcluster/conf
• for Redhat Linux - SGCONF=/usr/local/cmcluster/conf
To initialize the variables in /etc/cmcluster.config execute the
following command for the bash shell:
NOTE The leading dot is important.
. /etc/cmcluster.config
Then the command:
cd ${SGCONF}
will change into directory:
• For SUSE Linux - /opt/cmcluster/conf
•For Redhat Linux - /usr/local/cmcluster/conf
