Understanding Serviceguard Extension for SAP

Database package control script based on the current HA NFS toolkit.
The postfix tells that this file is required by the database failover
package dbC11.
/etc/cmcluster/C11/sapwas.cntl
Contains the SAP specific control logic by calling relevant routines of the
generic function pool /etc/cmcluster/sap.functions. This part of the
package should never be modified. This will ensure supportability of the
solution.
/etc/cmcluster/C11/customer.functions
Contains hooks that allow to customize or implement failover functions
to realize individual requirements without spoiling support for the
overall solution. If you have to change functions in
/etc/cmcluster/sap.functions copy them over to
/etc/cmcluster/customer.functions and modify them there. Never
modify /etc/cmcluster/sap.functions itself. Any function provided in
customer.functions overrides its equivalent in sap.functions. There
also is a similar file /etc/cmcluster/customer.functions in the
parent directory for global changes that have significance for more than
one SID.
/etc/cmcluster/C11/sapms.mon
Contains a script-based service monitoring implementation for SAP
Message Services. This file will only be needed if the SAP Message
Server gets specified as Serviceguard Service.
/etc/cmcluster/C11/sapdisp.mon
Contains a script-based service monitoring implementation for a SAP
Dispatcher. This file will only be needed if a SAP Dispatcher gets
specified as Serviceguard Service.
/etc/cmcluster/C11/saplc.mon
Contains a script-based service monitoring implementation for a SAP
liveCache instance. This file will only be needed if the liveCache gets
specified as Serviceguard Service. The file can monitor a standard
liveCache or the master liveCache of a hot standby system setup (hss).
/etc/cmcluster/C11/sapmdm.mon
Contains a script-based service monitoring implementation for a SAP
MDM. This file will only be needed if MDM servers get specified as
Serviceguard Service.
