Abstract

A lock control data structure for a unit of work of an application program. The unit of work has a set of threads of access for opening a set of objects accessible to the application program. The lock control data structure has a set of object-specific lock models corresponding to the set of objects, and a lock controller for locking each object in the set of objects. Information regarding the lock requirements for each object are stored in the corresponding object-specific lock model. The lock controller locks and unlocks each object in the set of objects based on the information stored in the corresponding object-specific lock model.
