Pre-staging messages at a remote location

Abstract

A method for message handling between a message producer and a remote message consumer in a shared queue computing environment. The method includes, receiving from a message producer, at least one message by a first queue manager. A first queue manager writes both the message data associated with at least one message, to a shared data repository, and a pointer, associated with the message data to a coupling facility, using an uncommitted key. The second queue manager, upon an indication that an uncommitted key is written to the coupling facility, reads the message from the shared data repository based on the pointer, and stores the message in an internal memory storage buffer. The first queue manager then commits a batch of messages. Finally, the second queue manager merges the pointer and the message from the internal memory storage buffer, in response to a remote message consumer requesting the message.
