Method, apparatus, system and computer program for reducing I/O in a messaging environment

Apparatus for reducing I/O in a messaging system comprising:

• a queue manager for managing at least one input queue;
• at least one log for logging message activity in the messaging system;
• at least one client;
• and a server application separate from the queue manager, the apparatus comprising:
• means for intercepting requests from at least one client to put messages to an input queue, before the messages reach said input queue;
• means for identifying said intercepted requests which refer to a message destined for the server application, wherein information associated with the server application indicates that the server application will process said message according to a predetermined manner, wherein a request associated with the server application for retrieving said message is transactional and wherein the server application uses a one-phase commit for retrieving said message;
• and
• means for matching said message with the server application's request such that the server application can retrieve the message.
