Serviceguard Extension for SAP on Linux Configuration – sap.config
Chapter 3146
Specification of the Packaged SAP Components
For each type of potentially mission-critical SAP software components
there exists a set of configuration parameters in SECTION 1 of the
${SGCONF}/<SID>/sap.config file. The information delivered here will
be specified exactly once and it will configure all packaged components of
a <SID> within the cluster. This is a central place of configuration, even if
the intention is to divide the components into several different packages.
The mapping of components to packages will be done automatically.
There is one subsection per package type:
• db: a database utilized by a SAP WAS-based application.
• ci: a SAP Instance that has SPOF services defined. This might be a
Central Instance with integrated Enqueue and Message Service
(DVEBMGS). It might also be a standalone Enqueue and Message
Service as part of a separate ABAP System Central Service instance
(ASCS). A Replicated Enqueue setup can be implemented by
configuring at least one additional package of type RE in
combination with this CI.
• arep: an ASCS Replicated Enqueue instance.
• rep: an SCS Replicated Enqueue instance.
• d: one or more virtualized SAP Application Instances that are
considered mission-critical due to special use cases.
• jci: a SAP JAVA System Central Services Instance that provides
Enqueue and Message Service to SAP J2EE engines that might or
might not be part of SAP Web Application Servers (SCS).
NOTE It is not allowed to specify a [j]ci and an [a]rep component as part of
the same package. Except Dialog Instance components of type d, each
component can be specified once at most. Apart from these exceptions,
any subset of the SAP mission critical components can be maintained in
sap.config to be part of one or more packages.
Logon to the primary host as root and open the file
${SGCONF}/<SID>/sap.config with a text editor.
