• 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
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 are: 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 relocatible 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.
The relocatible IP address of the instance should be specified in CIRELOC.
