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

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. Example:
rm /sbin/rc3.d/S<###>sapinit
ps -ef | grep sapstartsrv
kill <PID_of_sapstartsrv>
Module-based SGeSAP packages will handle the sapstart service agent automatically. For
SAP releases based on kernel 7.10 or higher, SGeSAP can also register an instance with the startup
framework as part of the package startup operation and de-register it as part of the package halt.
If the service agent is started via SGeSAP and configured to autostart the SAP instance, SGeSAP
will monitor the operation to make sure that the instance startup succeeds.
Installation Step: IS474
The configuration file needs to be applied and the package started.
This step assumes that the cluster as such is already configured and started. Please refer to the
Managing Serviceguard user's guide if more details are required.
The SGeSAP package configuration will be distributed to all nodes, verified on all nodes, and
activated by issuing the following command on the package configuration file that was created
and customized above:
cmapplyconf -P ./sap.config
