ABSTRACT:
A method is provided for splitting a system comprising a processor subsystem including a plural number (np) of processors, and an instance of a database. A number (nn) of nodes is selected that the system is to be split into. Each node may be provided with a processor subsystem including at least one processor. At least some of the nodes further include an instance of at least a portion of the database. A network is provided for communications among the nodes. At least some of the nodes that contain an instance of at least a portion of the database are automatically synchronized so that contents of the database that exist in plural nodes remain synchronized in at least some of the plural nodes whenever contents of the database at one of the nodes is changed. Systems with multiple processors, but without databases, may also be split in the same manner.
