Managing Serviceguard Extension for SAP, December 2007

Step-by-Step Cluster Conversion
SGeSAP Configuration
Chapter 3168
Global Defaults
The fourth section of sap.config is rarely needed. It mainly provides
various variables that allow overriding commonly used default
parameters.
OS770 Optional Step:
If there is a special demand to use values different from the default, it is
possible to redefine some global parameters. Depending on your need for
special HA setups and configurations have a look at those parameters
and their description in the SAP specific configuration file sap.config.
When using the HP Serviceguard Storage Management Suite with CFS
and shared access Option 3 (Chapter 2 – Planning the Storage Layout) it
is required to set the CTEXERELOC variable , because otherwise the
default initialization value would be NFSRELOC (DEFAULT:
${NFSRELOC}). CTEXERELOC should get initialized to DBRELOC or CIRELOC.
NW04S780 Optional Step for Netweaver 2004s:
This installation step only applies if Netweaver 2004s with SAP
Application Server 7.0 is installed.
SAP introduced a control framework with Netweaver 2004s and SAP
Application Server 7.0 that enables the management of SAP instances
from third party products using a defined application interface. This
control framework is implemented using a daemon process that is either
started by:
• the operating system during boot time or
• the SAP startup script when the instance is started.
During the installation of a SAP Netweaver 2004s Web AS, the SAPIinst
installer edits a file in /usr/sap/sapservices and adds a line for each
sapstartservice instance. During boot time an init script is executed
located in:
/sbin/init.d/sapinit
referenced by
/sbin/rc3.d/S<###>sapinit
The sapinit script reads the content in file /usr/sap/sapservices and
starts a sapstartsrv for each instance during OS boot time. This can
lead to error output in the boot messages log file as file systems for
exclusive shared storage is not available at that time.
