NONE as the Communication Method

Setting COMMUINICATION=NONE option lets you test start CA MIM without any cross-system communication capabilities. This method is used for pre-production testing and you cannot dynamically switch to alternative communication methods.

When you specify MIMINIT COMMUNICATION=NONE, no I/O operations are performed to DASDor CTC devices. Therefore, the Global Tape Allocation Facility (GTAF) cannot be activated. This global facility requires a cross-system communication method.
