XRC uses the cluster data set to keep track of master
session to which all SDMs in a cluster session are coupled. The cluster
data set must be accessible from, and cataloged on, the host on which
the cluster session is to be active and all recovery hosts for all
SDMs in the cluster session.
XRC uses the cluster data set name in the following form:
Where:
- ClusterName
- Specifies the value specified on XRC PARMLIB parameter of ClusterName
of the STARTUP category, or defaults to the host system name. The
name can be up to eight characters long. The name you specify for
the ClusterName cannot be the same as any XRC session_id.
- mhlq
- Specifies the master data set high-level qualifier that is used
to access the master data set. The mhlq must be one to eight
characters, and can be any name acceptable to TSO.
The following name is an example of a cluster data set
name:
SYS1.XCOPY.SYSTEM1.CLUSTER
