ABSTRACT:
A virtual computer system executes a virtual computer control program on a physical computer and thereby causes guest programs on the logical partitions, respectively. The virtual computer control program includes an error recovery module to periodically recover from an error in a cache memory, an error interruption handler module responsive to an interruption notice caused by an error which has occurred in the cache memory, to recover from an error in the cache memory, and an error data initialization module to recover from an error in the cache memory with shutdown or restart of one of the logical partitions as a momentum. And the virtual computer control program conducts recovery processing from an error in the cache memory.
