User's Guide

Specify SAPCCMSR_START=1 if there should be a CCMS agent started on the DB host automatically. You
should also specify a path to the profile that resides on a shared lvol
For example:
SAPCCMSR_START=1
SAPCCMSR_CMD=sapccmsr
SAPCCMSR_PFL="/usr/sap/ccms/${SAPSYSTEMNAME}_${CINR}/sapccmsr/${SAPSYSTEMNAME}.pfl
Global Defaults
The fourth section of sap.config is rarely needed. It mainly provides various variables that allow overriding
commonly used default parameters.
Optional Step: OS770
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.
Optional Step for Netweaver 2004s: NW04S780
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.
If the use of the SAP control framework is not required, then remove the reference link from the sapinit script.
Furthermore, any running sapstartsrv processes can be killed from the process list. For example:
# rm /sbin/rc3.d/S<###>sapinit
# ps -ef | grep sapstartsrv# kill {PID of sapstartsrv }
To make use of the sapstartservice configure the SAPSTARTSRV_START and SAPSTARTSRV_STOP
values. The sapstartsrv daemon is started and stopped accordingly. For example:
SAPSTARTSRV_START=1
SAPSTARTSRV_STOP=1
Optional Step: OS790
To enable the Workload Management (WLM) support of the dispatcher monitors specify: WLM_PROCMAP=1
The following example WLM configuration file illustrates how to favour dialog to batch processing.
