Method and device for controlling network computer system processing group

PURPOSE: To allow application service to call operation execution to be executed with respect to a host controlled by different processing servers. CONSTITUTION: At a step 100, user asks the execution request of a network function. At a step 102, whether a processing server is the designated processing server of an asked operation or not is decided. When it is the same as the designated processing server, a transferring process is finished to advance to a step 110. When it is not the same, the processing is advanced to the step 104 of an operation transfer loop 103 to decide a proper processing server. At a step 108, whether a receiving server is the designated processing server or not is decided and the processing is advanced from the transfer loop to a process execution part 109 for executing operation. At a step 114, the processing server retrieves the list of objects specified as the member of a group object Grp1 to confirm identification and then moves to a step 116 to control transfer and an execution task.
