Abstract

PURPOSE:To prevent dump from being leaked and to execute fault analysis within a short time by reading out an interface part formed in an external storage device from a ROM program at the time of generating a fault and dumping the contents of a main storage device to a dump area based on the read interface part. CONSTITUTION:When a fault is generated during the execution of an execution program in each device 1, the ROM program 11 is started. The ROM program 11 reads out the contents of a dump area interface part 21 set up in a specific area of a floppy disk device 2. The contents of the interface part 21 stores a dump area necessary for fault analysis as a table in each device. A table 31 and files 32a, 32b e.g. in the main storage device 3 are dumped to a dump area 22 in the floppy disk 2 based on the contents of the dump area table.

[Detailed Description of the Invention] [Summary] At least in a terminal control device, tally processing device, etc. that is equipped with an external storage device and is controlled by a program, when a failure occurs, the contents of the main memory bag W (MS) are stored externally. For example, when dumping to a floppy disk device using a ROM program common to each device, the main memory (MS)
By providing interface information regarding the above dump area in a specific area of the floppy disk device,
Based on the interface information, the ROM program dumps dump information on the main storage (MS) unique to each device to the dump area of the floppy disk device.

[Industrial application field]

The present invention provides at least a terminal control device, a total processing device, etc. that is equipped with an external storage device and is controlled by a program, and when a failure occurs, the contents of the main storage device (MS) are transferred to an external floppy disk device, for example. , relates to a dump method when dumping using a ROM program common to each device.

With the recent improvement in the performance of computer systems, the practical use of so-called online systems such as token generator systems and banking systems has been remarkable. Therefore, in the event that a failure occurs in the online system, the contents of the main memory (MS) necessary for failure analysis are transferred to an external floppy disk drive. It is configured so that it can be dumped to a file such as a computer, and then automatically started up immediately.

The dump control mechanism in such an online system is
Due to the ease of designing and implementing various online systems with different functions, and the ability to improve reliability, ROMs are usually composed of read-only memory (hereinafter referred to as ROM) and used in common for each device. It is.

On the other hand, in the event of a failure, the information on the main memory (MS) necessary for failure analysis that should be saved to an external floppy disk device etc. is generally located in a different area for each device. There is a need for a common dump mechanism, specifically, a dump method that can dump dump information from different areas of individual devices using a common dump mechanism, specifically, the ROM program described above.

[Prior art and problems to be solved by the invention] FIG. 2 is a diagram illustrating a conventional dump system.

First, in this figure, when a failure occurs in the terminal control device controlled by the program or the total processing device 1, etc., the main memory (M
S) Information on 3 (various types, tables, file contents)
31 and 32 to the dump area 22 of the external floppy disk device 2, an initial program loading (IPL) mechanism performs initial program loading (IPL) of the execution program 20, etc., and recovery is performed.

However, the floppy disk device 2 also stores execution programs and the like to be executed by the device l.
The dump amount on the main storage device if (MS) 2 to be dumped is the dump area 2 of the floppy disk device 2.
If the capacity is more than 2, nuclear storage device (MS)
The dump information on the device 2 must be limited, and normally, the dump is controlled in a fixed manner by the ROM program 11 built into the device 1.
``The printed board on which this ROM 11 is mounted is often common to several types of models.

Additionally, the data required for the dump differs for each model, and the ROM program (main memory) is different for each model.
Although the data on the main storage device (MS) 2 is arranged in accordance with 11 (the content of the fixed area on the MS) 2 is dumped, the failure data necessary for failure analysis is still Currently, not all of the data can be dumped.

Therefore, in the conventional system, it is often the case that all the data required for fault analysis is not collected for each of the nine models, and as a result, there is a problem in that a large number of man-hours are required for fault investigation.

In view of the above-mentioned drawbacks of the conventional art, the present invention utilizes a common ROM program with a fixed dump method.
), the purpose is to provide a method for dumping data in different areas for each model.

[Means for solving problems]

Figure 1 is a diagram showing an example of the configuration of the dumping method used in this event.

In the present invention, in a data processing system that includes at least an external storage device 2 and is controlled by a program, when a failure occurs, the contents of the main storage device (MS) 3 are transferred to the RO//I specific memory. ←4 When the program 11 dumps to the dump area 22 of the external storage device 2, the dump area ink face part 21 that specifies the area of the main storage device (MS) 3 to be dumped to the external storage device 2, The dump area interface unit 21 provided in the external storage device 2 is read out, and based on the contents, the main storage device (
The contents of MS) 3 (31, 32a, 32b) are configured to be dumped into the dump area 22 of the external storage device 2.

[Effect]

That is, according to the present invention, when a failure occurs in at least a terminal control device, a tally processing device, etc. that is equipped with an external storage device and is controlled by a program, the contents of the main storage device (MS) are transferred to an external front disk drive. For example, when dumping to a disk device using a ROM program common to each device,
By providing interface information (dump table) regarding the dump area on the main storage device (MS) in a specific area of the floppy disk device, the ROM program can Since the dump information on the storage device (IS) is dumped to the dump area of the floppy disk device, the main storage device (MS)
Since it is possible to specify the area for dump suppression required above, there is no omission of dumps necessary for fault analysis, and the effect of fault analysis being made in a short time can be obtained.
