Managing Serviceguard Extension for SAP Version B.05.10, December 2012

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 SAP ABAP or SAP add-in installations. Do not combine a database
with a liveCache in a single package.
• 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 ABAP Application Instances that are considered mission-critical
due to special use cases.
• jdb: a database exclusively utilized by J2EE engines that are not part of Application Server
Instances. Do not combine a database with a liveCache in a single package.
• 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 Application Servers (SCS).
• jd: one or more virtualized SAP JAVA Application Instances.
NOTE: It is not allowed to specify a db and a jdb component as part of the same package. 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 /etc/cmcluster/<SID>/sap.config
with a text editor.
Installation Step: LS600
Specify the relocatible IP address where the HA NFS shared filesystems can be reached. Format is
IPv4: nnn.nnn.nnn.nnn.
This value specifies the default for commonly shared filesystems. An override is possible for the
SAPDB ini-directory, the global transport directory and the central executable directory individually
by specifying values for SQLRELOC, TRANSRELOC, CTEXERELOC.
NOTE: All xxxRELOC parameters have to use the same syntax as the IP[]-array in the package
control file.
When using the HP Serviceguard Storage Management Suite with CFS and shared access Option
3 (chapter 2 — “Planning the Storage Layout”) the NFSRELOC does not need to be specified.
Example:
NFSRELOC=0.0.0.0
