ABSTRACT:
A system for relocating records in a database having a prime region and an overflow region in parallel with a service processing. The system is provided with a database relocation utility which acquires exclusive access to regions of the prime region and the overflow region for which the service processing has not acquired exclusive access. The system saves a predetermined number of records of the prime region and the overflow region into a data save area. Thereafter, the system relocates the records by packing them in one of the prime region and the overflow region.
