Abstract:
A method, computer program product, and computer system for identifying, by a computing device, an attribute of a lock object associated with data. It may be determined that the lock object is acquired by a first task performing a transaction with the data based upon, at least in part, the attribute of the lock object. The lock object may be acquired by a second task by releasing the lock object from the first task prior to the transaction with the data being completed, wherein the second task is a higher priority task than the first task.
