Unassigning a CMAS from a CICSplex definition

When you remove a CMAS involved in managing a CICSplex, the action you take depends on the state of communications between the CMAS to be removed and the maintenance point CMAS.

Before you begin

Ensure that there are no active MASs in the updated CICSplex connected to the CMAS to be removed.

Procedure

To display information about the CICSplexes associated with the local CMAS, click Administration views > CMAS configuration administration views > CICSplex definitions. This tabular view lists the CICSplexes defined to the local CMAS.

When the CMAS to be removed is currently accessible or will be accessible later to the maintenance point CMAS, you must do the following:
  1. Select the check box associated with the CMAS to be removed and click Unassign.
  2. Click Yes to remove the selected CMAS from the CICSplex.

    This action causes the selected CMAS to be immediately removed from the management of the CICSplex in the data repository for the maintenance point CMAS. Then, if the selected CMAS is currently accessible, its data repository is updated to reflect this change; otherwise, the action is placed in a pending status until the selected CMAS becomes accessible.

When the CMAS is not currently accessible and will never be accessible to the local CMAS, do the following:
  1. Select the check box associated with the CMAS to be removed and click Unassign.
  2. Select the FORCE check box from the Unassign view.
  3. Click Yes to remove the selected CMAS from the CICSplex.

    This action causes the selected CMAS to be removed from the management of the CICSplex in the data repository for the maintenance point CMAS. Because the selected CMAS is not accessible, the data repository for the selected CMAS is not altered to reflect this change.

Note: You cannot remove the association between a CICSplex and the maintenance point CMAS. If you determine that a different CMAS should be the maintenance point CMAS for the CICSplex, the entire CICSplex and all of its definitions must be deleted and re-created on the new maintenance point CMAS. For details, see Moving to a new maintenance point CMAS.
