XRC cannot dynamically accept changes to the cluster
data set. To change the characteristics of the cluster data set, follow
this procedure:
- Remove all coupled sessions from the cluster session (XCOUPLE
DELETE command for active sessions or XCOUPLE PURGE command for inactive
sessions). Issue the XSTATUS command to determine the SDMs coupled
through the cluster session.
- Reallocate the cluster data set.
- Issue the XCOUPLE ADD command for each of the sessions previously
coupled through the cluster session.
