Failed message error recovery using application specific error queues

A computer program product for use at a computer system that is network connectable along with one or more other computer systems to a network, the computer system including a queue manager that controls one or more message queues at the computer system, the computer program product for implementing a method for recovering from an messaging error, the computer program product comprising one or more computer-readable media having stored thereon computer-executable instructions that, when executed by a processor, cause the compute system to perform the following:

• receive an enqueue message from a sending application, the enqueue message including:
• an application message;
• a receive queue reference, the receive queue reference identifying a receive queue that corresponds to a corresponding receiving application;
• and
• an error queue reference to an application specific error queue for the sending application, the application specific error queue being a queue where failed application messages of the sending application are to be sent, the application specific error queue exclusively for the use of the sending application to isolate messages of the sending application from other applications such that other applications are prevented from accessing failed application messages of the sending application;
• enqueue the application message in a transmission queue;
• attempt to transfer the application message to the receive queue;
• detect that the application message was not delivered to the receiving application due to an error;
• identify the application message as a failed application message in response to detecting that the application message was not delivered;
• move the failed application message from the transmission queue to the application specific error queue for the sending application in response to detecting that the application message was not delivered, moving the failed application message to the application specific error queue preventing other applications at the computer system from accessing the failed application message;
• and
• return the failed application message along with appropriate error information from the application specific error queue to an error processing application configured specifically to handle failed application messages of the sending application, the failed application message returned to the error processing application subsequent to moving the application message to the application specific error queue for the sending application.

A computer system, the computer system comprising:

• a processor;
• a system memory;
• and
• one or more computer-readable media having stored thereon computer-executable instructions that, when executed by a processor, implement a queue manager, the queue manager being configured to:
• receive an enqueue message from a sending application, the enqueue message including:
• an application message;
• a receive queue reference, the receive queue reference identifying a receive queue that corresponds to a corresponding receiving application;
• and
• an error queue reference to an application specific error queue for the sending application, the application specific error queue being a queue where failed application messages of the sending application are to be sent, application specific error queue exclusively for the use of the sending application to isolate messages of the sending application from other applications such that other applications are prevented from accessing failed application messages of the sending application;
• enqueue the application message in a transmission queue;
• attempt to transfer the application message to the receive queue;
• detect that the application message was not delivered to the receiving application due to an error;
• identify the application message as a failed application message in response to detecting that the application message was not delivered;
• move the failed application message from the transmission queue to the application specific error queue for the sending application in response to detecting that the application message was not delivered, moving the failed application message to the application specific error queue preventing other applications at the computer system from accessing the failed application message;
• and
