Configuring SGeSAP/LX on Linux
The following sections contain information on configuring SGeSAP/LX
(Serviceguard Extension for SAP). It is assumed that a basic
Serviceguard cluster is up and running.
As mentioned in an earlier section of this document, references to
variable ${SGCONF} 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
The Serviceguard NFS toolkit also uses a installation directory. This
directory is different for SUSE Linux and Redhat Linux so any
references to variable ${SGROOT} can be replaced by the following
definition:
• For SUSE Linux - SGROOT=/opt/cmcluster
•For Redhat Linux - SGROOT=/usr/local/cmcluster
SGeSAP/LX uses a staging directory during the installation. As the
staging directory is different for SUSE Linux and Redhat Linux
references to variable ${SAPSTAGE} can be replaced by the following
definition:
• For SUSE Linux - SAPSTAGE=/opt/cmcluster/sap
•For Redhat Linux - SAPSTAGE=/usr/local/cmcluster/sap
Export the variables so they are available to the user environment:
