GLOBAL TRANSACTION SERIALIZATION

A method, computer program product, and a system to globally serialize transactions where a processor(s) establishes a communications connection a (serialization) resource and a resource manager for a distributed computing system. The processor(s) obtains a first request from an application executing on the resource for access to a global resource managed by the resource manager, for executing a transaction. The processor(s) implements a lock for the global resource in an object store of the resource manager over the communications connection. The processor(s) communicates the lock to the application, which executes the transaction and the processor(s) updates a memory with a record comprising attributes of the lock. The processor(s) obtains a second request from the application to terminate the lock, obtains, identifies the lock for the transaction, in the object store, and updates the object store to delete the lock.
