<p>PURPOSE:To access a data base without making a data base processing request part conscious of reestablishment of a communication path by absorbing the establishment processing of the communication path to the processing at the declaration of the use of communication path. CONSTITUTION:An application processing part 21 declares the use of a data base to be used for service and generates a data base operating instruction 22-1. Receiving the instruction 22-1, an instruction decoding part 23 starts an attachment processing part 24 at first. If the data base declared at its usage exists in another node, said processing part 24 opens a communication path in order to couple with the node logically and informs the generation of the communication path opening request to a stack processing part 26. Receiving said information, the stack part 26 secures a stack area 27 on a memory to stack a data base operating instruction 22-1, ready 22-2, etc, in a control system decoded in the instruction decoding part 23.</p> |
