Requesting Confirmation
Requesting confirmation is an efficient way to determine that the partner program has received all the data sent so far. If you plan to request confirmation during the conversation, the allocation transaction must indicate this fact when you request the allocation of the conversation.
If you use conversation verbs that do not request confirmation, you should not request the allocation of a conversation supporting confirmation services.
You can write a transaction program to participate in conversations that use confirmation requests and in conversations that do not use confirmation requests.
