OS445 Optional Step:
In case you want to automate Replicated Enqueue handling and use
follow-and-push failover semantics for[A]SCS/[A]REP packages:
The SGeSAP ENQueue Operation Resource needs to be specified for each
[A]SCS package and for each [A]REP replication package in the package
configuration files.
Example entries for a ASCS package configuration file:
RESOURCE_NAME /applications/sap/enqor/C11ascs
RESOURCE_POLLING_INTERVAL 30
RESOURCE_START AUTOMATIC
RESOURCE_UP_VALUE != "IDLE"
Example entries for an AREP package configuration file:
RESOURCE_NAME /applications/sap/enqor/C11ascs
RESOURCE_POLLING_INTERVAL 60
RESOURCE_START AUTOMATIC
RESOURCE_UP_VALUE != "SERVING"
You will need to copy /opt/cmcluster/sap/sap.config to
/etc/cmcluster if you use non-default package names. Default package
names for setups with Replicated Enqueue are ascs<SID>, scs<SID>
and ers<INR><SID>. Within the file, any non-default names have to be
specified explicitly.
ENQOR_ASCS_PKGNAME_<SID>=<non-default name_1>
ENQOR_SCS_PKGNAME_<SID>=<non-default name_2>
ENQOR_AREP_PKGNAME_<SID>=<non-default name_3>
ENQOR_REP_PKGNAME_<SID>=<non-default name_4>
