Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a response method of a host system, particularly when a plurality of CPU systems exist in one host system, and when the plurality of CPU systems
The present invention relates to a response method of a host system that allows a CPU system connected to the host system via the line to be recognized from the outside when one of the systems is connected to the line.

In recent years, with the development of data processing systems, it has become more common to perform processing via lines between terminal devices and centers, between centers, and the like.

In particular, in a center (that is, a host system), there may be a plurality of CPU subsystems with different architectures, such as when the amount of data processed is large, or when the system is migrated to a new system with a different architecture.

Of course, there is a device for connecting to the line, and this device is operated by an operator, so the host system and CP
The operator could not recognize whether the U system was connected to the line without looking at the device.

Therefore, a person wishing to use the host system had to contact the host system in advance by telephone or the like and inquire with the operator staying there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a host system response method that eliminates the above-mentioned drawbacks and can extremely easily and reliably recognize a CPU system connected to a line.

The purpose of this is to connect each CPU system (a system information storage section that stores its own CPU system identification information, an arrangement processing function section that performs arrangement processing to other host systems, and a line connected by the above-mentioned connection device). When a connection inquiry is made to the host system via the line from the coordination processing function unit of the CPU system of the other host system, The response processing function section of the CPU system connected to the line of the host system is achieved by sending the contents of the system information storage section of the own CPU system to the other CPU system.

The present invention will be described in detail below using the drawings. FIG. 1 is a configuration diagram of an embodiment of the present invention.

Host systems 1 and 2 are connected via line 5 by modems 3 and 4, and multiple CPU system N1゜01
and N2,02.

6 and 7 are line switching devices, which manually switch CPU system N1 or 01 to modem 3 and CPU system N.
2 or 02 to the modem 4.

Each CPU system has a console 8, 13° 18.2
3. It is equipped with at least CPUs 9, 14, 19, and 24, and each CPU also has a timing processing function section 10, 15, 20.
, 25, response processing function units 11.16, 21, 26, and system information storage units 12.17, 22, 27, respectively.

For example, as an old system, CPU system 01 and CPU
The U system 02 forms the host system 1 and the host system 2, respectively, and since the amount of data processing is overflowing, the new system will consist of the CPU system N1 of the processing function section and the CPU system N2 of the processing function section, forming the host system 1. It is often done to change the system to form the host system 2.

At this time, since the system is to be migrated to a new system, various tests are required, and the line switching device is switched manually, so the test operator in host system 1 can transfer the data to the operator in host system 2. Make a phone call, and on host system 2, select either the new or old CP.
I had to ask if the U system was connected.

Furthermore, in addition to testing, it is necessary in various situations to know which CPU systems are connected to a host system via a line because of the differences in processing content and procedures.

Of course, adding a special function to the line switching devices 6 and 7 to enable remote sensing may be considered as a solution, but if it will not be needed in the future, such as during the system migration stage, adding a special device is recommended. It is not a good idea to do so.

In the present invention, each CPU system includes an adjustment processing function section,
The above problem is solved by providing a response processing function section and a system information storage section, and sending the contents of the system information storage section to the arranging source when a connection status inquiry is made to the host system.

For example, the line switching devices 6 and 7 each have a CPU system N
1 and N2, and host system 1 connects the connected CPU systems to host system 2.

The system information storage unit 22 contains “In the host system 2,
PU system N2 is connected.

” is stored.

Therefore, when an inquiry is made from the adjustment processing function section 10 of the CPU system N1 in response to a specification from the console 8, the response processing function section 21 is sent to the system information storage section because the line switching device 7 is connected to the CPU system N2. The contents of 22 are sent as a telegram via line 5, and console 8 displays the message ``CPU system N2 is connected to host system 2.

" is displayed. Therefore, the operator does not need to make arrangements over the phone at all.

FIG. 2 is a more detailed explanatory diagram of the present invention.

In the figure, the same symbols as in the previous figure indicate the same parts as in the previous figure, and 28 and 29 are input/output processing units.

Job AAA and job B at system generation (startup)
The BB is set to be ready for operation as soon as it is activated.

That is, a job is being submitted, and the schedule processing function section 10 and response processing function section 21 each exist.

The operator of host system 1 accesses rSPATHONA from console 8 in order to know the CPU system of host 2.
This is the timing processing function unit 10 that gives the instruction AAJ.
The input/output processing unit 2B (AIM) is read by the input/output processor 2B (AIM) and issues an adjustment instruction.

In response to the instruction, the input/output processing unit sends a message r: CBBBJ to line 5.

At this time, if it can be sent without error, "OOJ is returned to the adjustment processing function unit 10.

Therefore, if "OO" is received, the system waits until the next access from the input/output processing section 29 is received.

However, for example, the line switching device 6 is actually the CPU system 0.
If it is connected to 1, it will not be able to receive “00” and “
"Connect error" is displayed on the console 8.

":c BBBJ message is sent to host system 2.
The response processing section 21 reads the response processing section 21, and the response processing section 21 reads the contents of the system information processing section 22: "N2 is connected to this line.

” is sent to the host system 1 in a write process, and a response is sent.

The adjustment processing section reads the content sent and responded to from the host system 2, writes the content to the console 8, and temporarily ends the process.

Therefore, the operator in the host system 1 can simply issue a command to the timing processing function section from the console, and the following information will be displayed on the screen.
The CPU system connected to host system 2 is displayed, so you can easily select the CPU system connected to the optical fiber line.
You can know the U5/- stem.

In the above embodiment of the present invention, the make-up processing function unit 10.1
5, 20, 25 and response processing function section 11.16, 2L
26 can be realized in exactly the same form, and the system information storage section can be filled with the own CPU system name as "This line is
*Connected to x.

It is only necessary to insert it into the X part of the sentence ``'', and it is extremely easy to implement.

FORTRAN. If Job A and Job B are created using source programs such as C0BOL, it is easy to compile them on each CPU system and input Job A and Job B into the system as executable formats, which reduces development costs. .

Of course, in the above embodiment, each CPU system has an arrangement processing function section and a response processing function section, but
The present invention is not limited to this, as long as the timing processing function section and the response processing function section are associated with each other via a line or the like.
