ABSTRACT:
In accordance with the present invention, a messaging system utilizes a local queue manager to receive messages intended for other processes. Messages received by the local queue manager are stored onto a local persistent storage device when a process sending the message has completed the sending action. The local queue manager then sends the message to an appropriate recipient. When the message has been received and confirmed, the recipient removes the message from the persistent storage device. If a hardware or software failure occurs, the message is stored and can be re-sent after the failure is corrected. In certain embodiments, a message writer is operable to communicate the message to the receiving process and remove the message from the queue after sending it to the receiving process. In certain embodiments, a message communicated by the sending process comprises a first format, and a message collector is operable to format the message received from the sending process into a standard format for transport to the local queue manager and storage on the persistent storage device.
