Managing Serviceguard Extension for SAP Version B.05.10, September 2010

• 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
Subsection for the DB component: OS610
SGeSAP performs activities specific to the database you use. Specify the underlying database
vendor using the DB parameter.
Possible options include ORACLE and MAXDB. Refer to the SGeSAP release notes to see whether
the required vendor is available for the SAP application component.
Example:
DB=ORACLE
Specify the relocatable IP address of the database instance. Be sure to use exactly the same syntax
as configured in the IP[]-array in the package control file.
Example:
DBRELOC=0.0.0.0
In the subsection for the DB component, there is an optional paragraph for Oracle and
SAPDB/MAXDB database parameters. Depending on your need for special HA setups and
configurations, have a look at those parameters and their description.
Subsection for the CI component: OS620
Provide information about the Central Instance if it will be protected by SGeSAP. Set the
parameter CINAME to the SAP instance name where ABAP Enqueue and Message Service are
located.
This usually is the Central Instance or the ABAP System Central Service. The name is either
DVEBMGS or ASCS. Note that the instance ID as defined by CINR is not part of CINAME.
Set the parameter CINR to the Instance ID of your Central Instance where ABAP Enqueue and
Message Service are located. This is most likely a SAP Central Instance or a ABAP System Central
Service Instance.
