Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of storing information in a memory area when an error occurs in a computer.

[0002]

2. Description of the Related Art In a computer system, when an error occurs during processing, in order to more easily determine the cause of the error, various information at the time of occurrence and recovery of the error are written to a memory area for storing an error. The cause is determined by analyzing the contents of the abnormality information.

As shown in FIG. 4, the abnormality information storage memory area can store a plurality of "abnormal information", and from "abnormal information # 1" to "abnormal information #N" in the order of abnormality occurrence / recovery time. ”Are sequentially stored.

Here, the capacity of the memory for storing abnormality information is limited, and accordingly, the storage amount of abnormality information is also limited. For this reason, the area to be stored next to “abnormal information #N”, which is the last of the abnormal information storage memory area, is “abnormal information # 1”, and the oldest information area is overwritten with new abnormal information.

[0005]

In the conventional processing method,
Although it depends on the situation at the time of occurrence of the abnormality in the computer, in the case of an abnormality that occurs repeatedly, all of the abnormality occurrence / recovery information is stored as “abnormality information”.

Therefore, as shown in FIG. 5, a large amount of similar abnormality information that differs only in the time of occurrence / recovery of abnormality is stored in the memory area for storing abnormality information. Sometimes it becomes information.

In this case, the other important abnormal information is overwritten in the abnormal information storing memory area, and as a result, the abnormal information disappears, so that the cause cannot be investigated.

It is an object of the present invention to provide a processing method capable of preventing other important abnormal information from being erased by overwriting even when the same abnormal information repeatedly occurs.

[0009]

According to the present invention, it is determined whether or not the abnormal information that has occurred is the same as that of the previous time, and the area for storing the abnormal information that has repeatedly occurred is classified into another area or a single area or a continuous block. This prevents the other important abnormal information from disappearing due to the same abnormal information repeatedly generated, and is characterized by the following method.

(1st invention) When an abnormality occurs, the computer sequentially stores the abnormality information in an abnormality information storage memory area having a limited capacity, and overwrites the old abnormality information when the abnormality information exceeds the capacity. The memory area is divided into a memory area for storing "normal abnormality information" and a memory area for storing "continuous abnormality information", and differs from the previous abnormality information when abnormality information is detected. In this case, the "normal abnormality information" is sequentially stored in the memory area for storing the "normal abnormality information", and the same abnormality information is sequentially stored in the memory area for storing "continuous abnormality information".

(2nd invention) A computer which, when an abnormality occurs, sequentially stores the abnormality information in a memory area for storing abnormality information having a limited capacity, and overwrites old abnormality information when the abnormality information exceeds the capacity. In the abnormality information storage processing method, the memory area is divided into a block for storing “abnormal information (single)” and a block for storing “abnormal information (continuous)”. If it is different from the above, it is sequentially stored in the "abnormal information (single)" storage block, and if it is the same, it is sequentially stored in the "abnormal information (continuous)" storage block.

(Third invention) When an abnormality occurs, the computer sequentially stores the abnormality information in a memory area for storing abnormality information having a limited capacity, and overwrites the old abnormality information when the abnormality information exceeds the capacity. The memory area is divided into a block for storing "abnormal information (single)" and a block for storing "abnormal information (continuous)" having two storage blocks, and the abnormal information is detected. If it is different from the previous abnormality information, it is sequentially stored in the "abnormal information (single)" storage block, and if it is the same abnormality information, it is stored in the two "abnormal information (continuous)" storage blocks. The abnormality information is stored in a block, and the abnormality information and the number of occurrences are stored in one block.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIG. 1 shows an abnormality information storage processing procedure and a memory area structure according to an embodiment of the present invention.

As shown in FIG. 1A, a memory area for storing abnormality information is divided into two parts, a memory area 1 for storing "normal abnormality information" and a memory area for storing "continuous abnormality information" divided into blocks. 2, and the continuous abnormality information is stored in the same block in the memory area 2 for storing “continuous abnormality information”.

In the process of storing the abnormality information, as shown in FIG. 2B, when the abnormality information is given, it is checked whether or not this information is the same as the previous one (S1).
Abnormality information having different contents is sequentially stored in the "normal abnormality information" storage memory area 1 (S2), and when abnormality information having the same content is detected, it is sequentially stored in the "continuous abnormality information" storage memory area 2 side. (S3).

For example, after detecting and storing “abnormal information # 2”,
Next, when the detected abnormality content is the same as “abnormality information # 2”, it is stored in “abnormality information # 21 of block 2” in the “continuous abnormality information” storage memory area.

Next, the content of the detected abnormality is also "abnormality information # 2".
In the case similar to the above, it is stored in “abnormality information # 22 of block 2”.

As described above, the continuous abnormality information is sequentially stored in the memory area 2 for storing "continuous abnormality information", and the "abnormal information # 21 of block 2" is followed by the "abnormal information # 21 of block 2". Since the information is stored, all the continuous abnormality information is stored in “block 2”.

As a result, the continuous abnormality information is sequentially stored in the “continuous abnormality information” storage memory area 2, so that the information in the “normal abnormality information” storage memory area 1 is overwritten by the continuous abnormality information. Therefore, it is possible to prevent the information from disappearing.

(Second Embodiment) FIG. 2 shows an abnormality information storage processing procedure and a memory area structure according to an embodiment of the present invention.

In the present embodiment, when successive abnormal information is stored, the number of stored abnormal information is limited.

As shown in FIG. 3A, the memory area 3 for storing abnormal information includes blocks # 1, # 3 to #n for storing "abnormal information (single)" and "abnormal information (continuous)". The blocks are divided into storage blocks # 2-1 to # 2-10. When the abnormality information is sequentially stored in the abnormality information storage memory area 3 and the abnormality information having the same content is detected, the abnormality information is sequentially stored in the “abnormal information (continuous)” storage block.

In the storing process of the abnormal information, as shown in FIG. 3B, it is checked whether or not the abnormal information is the same as the previous one (S4). It is stored in the block (S5), and if it is the same abnormality information, it is stored in the “abnormal information (continuous)” storage block (S5)
6).

For example, after detecting and storing "abnormal information # 2-1", if the next detected abnormality is the same as "abnormal information # 2-1", the "abnormal information (continuous)" storage block is stored. In “abnormality information # 2-2”.

Next, the content of the detected abnormality is referred to as "abnormality information # 2-
In a case similar to "1", it is stored in "abnormality information # 2-3". As described above, the continuous abnormality information is sequentially stored in the “abnormal information (continuous)” storage block, and the “abnormal information # 2” is stored.
Since “−10” is stored in “abnormality information # 2-1”, all the continuous abnormalities are stored in “abnormality information # 2”.

As a result, continuous abnormal information is sequentially stored in the "abnormal information (continuous)" storage block.
The information in the memory area for storing “abnormal information” is not overwritten by the continuous abnormal information, so that the information can be prevented from disappearing.

In this embodiment, since the abnormality information storage area is divided into two parts in advance in the first embodiment, the use efficiency of the abnormality information storage area is reduced, whereas the abnormality information storage area is dynamically used. Therefore, the use efficiency of the abnormality information storage area is good.

(Third Embodiment) FIG. 3 shows an abnormality information storage processing procedure and a memory area structure according to an embodiment of the present invention.

In this embodiment, when storing continuous abnormal information, only the first and last abnormal information contents and the total number of abnormal information are stored, and the rest are not stored.

As shown in FIG. 3A, the memory area 4 for storing abnormal information includes blocks # 1, # 3 to #n for storing "abnormal information (single)", and the first and last two blocks. Block # 2- for storing "abnormal information (continuous)"
The blocks are divided into 1 to # 2-m. When the abnormality information is sequentially stored in the abnormality information storage memory area, if the same abnormality information is detected, the abnormality information is stored in two blocks of “abnormal information (continuous)” storage block. The abnormality information and the number of occurrences are stored in one of the blocks.

In the process of storing the abnormality information, as shown in FIG. 3B, it is checked whether or not the abnormality information is the same as the previous one (S7). The information is stored in a block (S8), and if it is the same abnormality information, the content and the number of abnormality information are stored in the "abnormal information (continuous)" storage block (S9).

For example, after detecting and storing "abnormal information # 2-1", if the next detected abnormality is the same as "abnormal information # 2-1", the "abnormal information (continuous)" storage block is stored. Is stored in the “abnormality information # 2-m”, and the number of pieces of abnormality information is also stored.

Next, the content of the detected abnormality is referred to as "abnormality information # 2-
In a case similar to “1”, the information is stored in “abnormality information # 2-m”, which is the same storage unit as described above, and the number of abnormalities is further increased by +
The number of set information is stored. In this way, for the continuous abnormality information, the first and last abnormality information contents and the total number of abnormality information are stored in the “abnormal information (continuous)” storage block.

As a result, the continuous abnormality information is stored in the "abnormal information (continuous)" storage block, so that the continuous abnormality information does not overwrite the information in the "abnormal information" storage memory area. Can be prevented from disappearing.

In this embodiment, the use efficiency of the abnormal information storage area is the best, but the number of collected abnormal information is the minimum.

[0036]

As described above, according to the present invention, it is determined whether or not the abnormal information that has occurred is the same as the previous one, and the area for storing the abnormal information that has repeatedly occurred is stored in another area or a single / continuous block. Since the information is stored separately, it is possible to prevent other important abnormal information from being lost due to the same abnormal information repeatedly generated.
