Method for ordering parallel operations in a resource manager

A resource manager in which a plurality of operations within a transaction is applied by a client application (16, 17, 18) to the resource manager (10), the resource manager comprising:

• receiving means for receiving a plurality of operations from the client application (16, 17, 18) in a logical order, the client application (16, 17, 18) indicating to the resource manager (10) that these operations can be applied in parallel;
• means for implementing the operations in parallel and means for controlling the parallel operations to ensure that the plurality of operations is executed such that the result of the parallel execution is the same as the result that would have been achieved by serial execution in the logical order.

A computer program product stored on a computer readable storage medium for ordering physically parallel operations instructed by a client application (16, 17, 18), comprising computer readable program code means for performing the step of:

• controlling operations, in a transaction entered into between the client application and a resource manager, said plurality of operations being implemented by the resource manager in parallel, the operations being executed to ensure that the plurality of operations is executed such that the result of the parallel execution is the same as the result that would have been achieved by serial execution in the logical order.
