Changing the characteristics of a cluster data set

XRC cannot dynamically accept changes to the cluster data set. To change the characteristics of the cluster data set, follow this procedure:

  1. 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.
  2. Reallocate the cluster data set.
  3. Issue the XCOUPLE ADD command for each of the sessions previously coupled through the cluster session.
