Match transaction request and response message
Mismatched transaction request and response message means that the current transaction request receives the response message of the previous transaction request. Because UDTT JCA LU0 Connector uses a queue buffer to keep the messages, the message is not removed until the application reads the message. So there can be problems if the application does not read the message for some reason.
Avoid the mismatch problem by following ways:
Verify the message content to match the transaction request and response.
Add a new JCA verb "SYNC_CLEAR_MSG_QUEUE" to clean the message queue. The application can call this verb before sending transaction data.
