Abstract

PURPOSE:To correct a program in a short time by correcting and holding the load module of a control processor when a software fault occurs or the function is changed with a communication processor and then correcting the load module of the communication processor through an IPL. CONSTITUTION:A communication processor 2 is set under a communication- enable state by applying an IPL 6 to an LM 4 via an optical transmission line 3 against the processor 2 from a control processor 1. Then the program correction of the processor 2 is required in case a software fault occurs or the function is changed with the processor 2. In this case, a part 5 of the LM 4 is changed to the processor 1 with application of a command carried out via a console 7. Thus the LM 4 of the processor 1 is held as a new program. Then the IPL 6 is applied for correction of an LM 8 of the processor 2 and a new program is obtained. In such a way, the program of the processor 2 is easily corrected in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program modification method, and more particularly to a program modification method for a communication processor in a communication system constructed by multiprocessors.

[Prior Art] Conventionally, this type of program modification method has been carried out as shown in FIGS. 2, 3, and 4.

The program modification method shown in FIG. 2 is such that the offline processor 11 modifies the source module (hereinafter referred to as SM) '12 by inputting a command from the console 13, and converts it into a file 14 to modify the source module (hereinafter referred to as LM).
Create 15. Transfer the LM15 to a floppy disk (
Hereinafter, input to the management processor 1 via the FD) 16,
A part of the program of the communication processor 2 is modified by IPL6.

The program modification method shown in FIG.
At this point, only the corrected part 5 is created by inputting a command from the console 7, and the - part of the program of the communication processor 2 is corrected by data transfer 8.

In the program modification method shown in FIG. 4, a part of the program of the communication processor 2 is modified using the testing device 21.

[Problems to be Solved by the Invention] The conventional program modification method described above has drawbacks as shown in the attached table. Below, the drawbacks will be explained one by one.

The method shown in FIG. 2 takes a long time to complete the correction.

In the systems shown in FIGS. 3 and 4, the modified portions are not retained during re-IPL, so it is necessary to modify the program each time IPL. Furthermore, since there is only one corresponding communication processor 2, it is necessary to modify the same program as many times as there are required processors.

The method shown in FIG. 4 requires test machines 21, and it is necessary to prepare the test machines 21 in the number corresponding to the processors, or to connect them to the processors one after another.

[Means for Solving the Problems] The present invention has been made for the purpose of proposing a program modification method that can modify a program without using an offline processor or directly modifying the program of a communication processor. It is something that

In order to achieve such an object, the present invention provides a program modification method in a communication system having a communication processor and a management processor that manages load modules to be loaded into the communication processor, the program modification method being implemented when a software failure occurs or the function of the communication processor is At the time of change, modify and maintain the load module on the management processor, and perform IPL
By doing so, the load module of the communication processor is modified.

[Example] Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and the same parts as in FIGS. 2, 3, and 4 are designated by the same reference numerals.

In the figure, 1 is a management processor, 2 is a communication processor, and they are connected to each other via an optical transmission line 3. Further, 4.8 is the LM of the management processor 1 and the communication processor 2, 6 is the IPL, and 7 is a console for inputting commands to the management processor 1.

By performing IPL6 on the LM4 from the management processor 1 to the communication processor 2 via the optical transmission path 3, the communication processor 2 becomes in a communicable state. Here, when a software failure occurs or when it is necessary to change the function, the program of the communication processor 2 must be modified.

In that case, the LM4 of the management processor 1 is maintained as a new program by changing a part 5 of the LM4 by inputting a command from the console 7 to the management processor 1. Thereafter, by performing IPL6 once v1, LM8 of the communication processor 2 is modified and becomes a new program.

As a result of the above, the program of the communication processor 2 can be modified easily in a short time.

[Effects of the Invention] As described above, the present invention provides a program modification method in a communication processor system having a communication processor and a management processor that manages load modules to be loaded into the communication processor, When a failure occurs or a function is changed, the load module on the management processor is corrected and retained, and the load module of the communication processor is corrected by performing an IPL. This has the effect of allowing programs to be corrected in a short time because no offline processor is used. There is. Furthermore, after the load module of the management processor is modified once and the IPL is performed on the communication processor, there is also the effect that the modified contents are retained even if the IPLL is performed again.
