CREFRESH operation (XRC)

Use the CREFRESH operation to refresh a cluster session and its associated address space. To enable a cluster address space after setting up the XRC PARMLIB parameter of ClusterMSession and optionally ClusterName, issue the following MVS MODIFY command:

F ANTAS000,CREFRESH

You may use this operation to clear up a cluster session. Specify the optional parameter of FORCE with this operation:

F ANTAS000,CREFRESH FORCE

Note: FORCE does not remove the cluster address space. It cleans up the XRC control blocks and enables the cluster address space to be started again by using the normal CREFRESH command. To remove the cluster address space, use the MVS operator CANCEL command.

You may use this operation to disable clustering. Specify the optional parameter of DISABLE with this operation:

F ANTAS000,CREFRESH DISABLE

DISABLE causes the same action as if you had coded ClusterMSession(disabled) in the parmlib, then issued a normal CREFRESH. The value of ClusterMSession in the parmlib is not changed.

To use the CREFRESH command to start a cluster other than the one specified on the ClusterName parameter in the XRC PARMLIB, issue the following command:

F ANTAS000,CREFRESH clustnam

Note that if a cluster name is specified on the CRFERESH command, all other cluster-related attributes (such as ClusterMSession) remain the same.
