Smart message delivery based on transaction processing status

A computer system for message delivery to a transaction processor, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• detecting an enqueued message in the request queue;
• in response to detecting the enqueued message in the request queue, determining if an expire time associated with the detected message exceeds an estimated delivery time;
• in response to determining that the expire time associated with the detected message does not exceed the estimated delivery time, discarding the detected message from the request queue;
• in response to determining that the expire time associated with the detected message exceeds the estimated delivery time, waiting until a transaction allowed event occurs;
• in response to the transaction allowed event occurring, determining if the detected message has not expired;
• and
• in response to determining that the detected message has not expired, sending the detected message to the transaction processor.

A computer program product for message delivery to a transaction processor, comprising:

• one or more computer-readable storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:
• program instructions to detect an enqueued message in the request queue;
• in response to detecting the enqueued message in the request queue, program instructions to determine if an expire time associated with the detected message exceeds an estimated delivery time;
• in response to determining that the expire time associated with the detected message does not exceed the estimated delivery time, program instructions to discard the detected message from the request queue;
• in response to determining that the expire time associated with the detected message exceeds the estimated delivery time, program instructions to wait until a transaction allowed event occurs;
• in response to the transaction allowed event occurring, program instructions to determine if the detected message has not expired;
• and
• in response to determining that the detected message has not expired, program instructions to send the detected message to the transaction processor.
