Interfaces for a Transactional Asynchronous Batch-Supported Send Adapter

A send adapter can create and control transactions when transactional transmission of messages is required. To support transactional send, an adapter needs to implement the following interfaces:

• IBTTransport

• IBaseComponent

• IBTTransportControl

• IPersistPropertyBag

• IBTBatchTransmitter

• IBTTransmitterBatch

• IBTBatchCallBack

  An adapter creates an MSDTC transaction and returns a pointer to that object in the call to the BeginBatch method of the IBTTransmitterBatch interface. The Messaging Engine calls this method to obtain a batch with which it posts outgoing messages to the send adapter. When the adapter finishes the send operation and commits or rolls back a transaction, it notifies the Messaging Engine of the result of the transaction by using the DTCCommitConfirm method of the IBTDTCCommitConfirm interface.

  The following figure shows the interaction between the transport proxy and the send adapter when performing a transactional send operation.
