Example: coupling existing coupled XRC sessions through a cluster session

The following scenario describes the steps needed to couple existing coupled XRC sessions using a cluster session to the same master session. The scenario provides the steps for converting existing coupled sessions for a single logical partition. These same steps can be used for other logical partitions. The master data set for master session CXRC must be accessible from the logical partition. In this example, the XRC sessions are currently coupled to the CXRC master session.

Perform the following steps to couple existing XRC coupled sessions through a cluster session:

  1. Allocate a cluster data set with the name SYS1.XCOPY.ARIZONA.CLUSTER. SeeAllocating the cluster data set for details on how to allocate the cluster data set.
  2. Update the ANTXIN00 member in parmlib to include the following XRC parmlib parameters under the STARTUP category: 
    ClusterMSession(CXRC) -
ClusterName(ARIZONA)
  3. Issue the following XRC commands for each XRC coupled session in the logical partition. You must ensure that all coupled sessions must are first suspended before they can be coupled through a cluster session: 
    XSUSPEND session_id VOLUME(ALL)
XCOUPLE session_id DELETE
  4. Issue the following MVS console command to activate the cluster session: 
    F ANTAS000,CREFRESH
  5. Issue the following XRC command for each session that you previously suspended: 
    XCOUPLE session_id ADD MSESSION(msession_id)
