Abstract
Systems and methodologies are provided in a lock hierarchy arrangement wherein upon release of all child locks associated with a parent lock, then such parent lock is also released. The present invention supplies each lock with sufficient information to determine its own life time. Such framework enables a higher degree of transaction concurrency in a database, and mitigates an over locking thereof, thus conserving system resources.
