MNPS planned and forced takeover processing

The two types of MNPS takeover processing that can be performed are:

MNPS planned takeover is a more orderly takeover activity, forcing the target application to first enter a state, such as SNPS recovery pending, which indicates that recovery of some sort is necessary.
MNPS forced takeover is a more dynamic takeover activity, in which the takeover application requests that the application to be taken over be shut down even in cases where the target application is currently active and operational.

During either type of takeover attempt, you might notice a peak in storage usage on the new owning VTAM®. When takeover is complete, storage usage should go back down. A VARY INACT of an HPR connection being moved because of multinode persistence recovery processing will not be processed until takeover processing has completed.

Restriction: The OPEN will fail for an application program recovering for a failed generic resource application program if the recovering VTAM does not support generic resources or does not connect to the same generic resource structure.
