Abstract

Disclosed is a technique to enable a database management system to manage locks on behalf of parallel processes executing in support of a single transaction so that: 1. all real deadlocks can be detected 2. no false deadlocks are detected 3. lock requests submitted on behalf of the same transaction do not conflict unless the specified lock is one in which conflict is desirable.
