A method of dynamic linkage including: receiving a request to launch a program; checking a system memory for the program; reserving a unique memory block of the system memory for the program and loading the program into the unique memory block if the program is not found in the memory of the system; performing internal memory relocations for the program if the program is not found in the memory of the system; ensuring that a library required by the program has been loaded into the system memory if the program is not found in the memory of the system; and invoking the program.

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.
