Switching SGeSAP Off and On
This section provides a brief description of how to switch off SGeSAP for
ABAP systems with storage layout option 1 of chapter 2 (NFS-based).
Your individual setup may require additional steps that are not included
in this document. Completely switching off the SGeSAP Integration
means that the SAP system will not run on the relocatable IP address
any longer.
Switching Off SGeSAP
Perform the following steps to unconfigure SGeSAP:
SO010: Switch off step:
If the SGeSAPpackages are still running, halt them using:
cmhaltpkg <package>
SO020: Switch off step:
Turn on the debug mode of the SGeSAP Integration. Then Serviceguard
can provide all the file systems and relocatable IP addresses, but the
scripts do not start the database or SAP instances. If a file named debug
exists in /etc/cmcluster SGeSAP Integration packages start and no
SAP specific script starts.
If you have more than one SAP application within the cluster you can
also turn on debug mode for specific systems. If the file
/etc/cmcluster/<SID>/debug exists, the additional scripts for this
system are not started. Other systems are controlled as usual by
Serviceguard.
SO030: Switch off step:
Start the package(s) with:
cmrunpkg <package>
