Method and system of committing operations of a synchronized transaction

A method and system for combined commit transaction request and subsequent operation request for committing the operations of a synchronized transaction by one or more applications ( 301, 4001, 501 ) on a resource manager ( 302, 402, 502 ). The method comprises: receiving a combined request ( 310, 410, 510 ) for an operation and a request to commit any outstanding synchronized transaction; committing the outstanding transaction ( 311, 414, 512 ); and processing ( 313, 413, 517 ) the requested operation outside the outstanding transaction. For example, in an asynchronous messaging process, the combined request specifies an option in a get operation request to commit any outstanding units of work prior to carrying out the get operation.
