This online system includes a plurality of intelligent processors 1 (only one is shown in FIG. 1), which are workstations, for example, and a first processor, which is, for example, a disk device, which is under the control of the intelligent processor 1 and stores load modules. The storage area 2 is connected to the intelligent processor 1 by a communication line (connected online) to a second storage area 3 which is, for example, a disk device and is under the control of the intelligent processor l and stores a replacement load module. It is configured to include a control processor 4, which is, for example, a center computer, and a replacement load module storage area 5, which is, for example, a floppy disk device, which is under the control of the control processor 4 and stores replacement load modules. Note that the first storage area 2 that stores the load module and the second storage area 3 that stores the In load module can exchange roles with each other.
The replacement load module is stored in the first storage area 2, and the second
It is also possible to store the load module in the storage area 3 of .

Each intelligent processor 1 receives a storage area identification means 11, for example, a table on a memory, for identifying a first storage area 2 and a second storage area 3, and receives a replacement load module from a control processor 4 to The load module receiving means 12, which is, for example, a communication control application program, is stored in the storage area 2 or the second storage area 3 of the intelligent processor 1; It is configured to include a load module execution means 13 which is a loader.

The control processor 4 is configured to include a load module sending means 41, which is, for example, a communication control application program, which sends a replacement load module to the intelligent processor 1.

The storage area identifying means 11 stores in which of the first storage area 2 and the second storage area 3 the load module and the replacement load module are stored.

In response to a request to receive a replacement load module from the load module transmission means 41, the load module reception means 12 refers to the storage area identification means 11 and locates the storage location of the replacement load module requested for reception in a first storage area. 2 and the second storage area 3, and stores the replacement load module received from the load module transmitting means 41 in the first storage area 2 or the second storage area 3, and sets the storage location to the storage area. The identification means 11 is notified.

The storage area identification means 11 is stored in the storage area 2 of
The storage location of the load module is set to the first storage area 2 and LB1.
Suppose you are doing i. Therefore, the load module receiving means 12 refers to the storage area identifying means 11 and selects the second storage area 3 in which no load module is stored, the storage location of the replacement load module that has been requested to be received from the load module transmitting means 41. Then, the replacement load module δ sent from the load module sending means 41 is received and stored in the second storage area 3.

Next, upon receiving the transmission completion notification of the replacement load module transmitted from the load module transmission means 41, the load module reception means 12 causes the storage area identification means 11 to store the load module and the replacement load module. It is notified that the location is to be stored in the opposite manner, that is, the second storage area 3 where the replacement load module is stored is to be stored as the storage location of the load module.

The storage area identifying means 11 stores the second storage area 3 in which the replacement load module is stored as the storage location of the load module.

When a user of intelligent processor 1 loads a load module, intelligent processor 1
The user requests the load module execution means 13 to load the load module.

The load module execution means 13, which receives a load module load request from the user of the intelligent processor 1, refers to the storage area identification means 11, determines the storage location of the load module in the second storage area 3, and processes the load request. Load the replacement load module into memory as the existing load module.
