Stopped transactions

If IMS stops a destination transaction, the action taken by the destination system varies based on the type of request. Requests can be conversational or nonconversational.

For a primary request that is not conversational or that starts a conversation, IMS sends an error message to the input terminal and cancels the message.

For a primary request that continues a conversation or a secondary request, IMS enqueues the message. If the request is the first one received for that stopped transaction, IMS also sends a message to the MTO at that transaction's local system.
