  • Managing locks affected by planned or unplanned reconfiguration of locking facilities
    Patent number: 6658513
    Abstract: Changes in locking configurations are managed. A locking configuration includes one or more locking facilities and the one or more locking facilities include one or more locks. When a change in a locking configuration, either planned or unplanned, is detected, one or more of the locks are redistributed. For example, one or more of the locks affected by the change are moved from one or more of the locking facilities to one or more other locking facilities. This redistribution is independent of the location of the data associated with the one or more locks being moved. Thus, data and locks may be moved independently of one another and without affecting one another. Further, the redistribution can take place while the system is available or mostly available, thereby minimizing downtime.
