OTMA program switch without ISRT to I/O PCB

When several switches occur in sequence and none inserts back to the I/O PCB, message DFS2082 is sent back to the OTMA client.

The last program switched to, Program C, does not insert back to the I/O PCB. IMS therefore generates message DFS2082 for the OTMA client.

Attention: If program C runs in a remote IMS through MSC and does not insert back to the I/O PCB, the remote IMS does not issue message DFS2082. However, in this case, the OTMA client program might hang and the front-end IMS control region will experience a build up of its control blocks. This kind of build up could result in a storage-related system outage. Restarting IMS releases the control blocks.
