DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an error log file control method in a computer system.

[0002]

2. Description of the Related Art A file for storing an error log in a computer system is usually a semiconductor memory device (RA).
M, hereinafter simply memory). The conventional error log file control method controls one error log file with a static capacity or controls one error log file with a dynamic capacity. That is, the error log file has a fixed length in the control with a static capacity, and the error log file has a variable length in the control with a dynamic capacity.

[0003]

However, in the above-described control with a static capacity, there is a problem that the user must refer to the contents of the error log file before updating the error log file. . Further, in the above-described control with a dynamic capacity, there is a problem that the limit capacity of a memory provided with an error log file must be constantly monitored. Further, in the above-described conventional control, there is a problem that occurrence of an error and logging to an error log file are not linked.

Accordingly, an object of the present invention is to reduce the number of times a user refers to the contents of an error log file,
An object of the present invention is to provide an error log file control method in which the number of times of monitoring the limit capacity of the memory is reduced. It is another object of the present invention to provide an error log file control method in which the occurrence of an error and the logging to an error log file are linked.

FIG. 1 is a block diagram of a computer system to which an embodiment of an error log file control system according to the present invention is applied. In FIG. 1, 1 is a central processing unit (CPU), 2 is a main memory for storing programs and the like, 3 is a memory for storing two error log files A and B, 4 is an input device (for example, a keyboard), 5
Is an output device (for example, a CRT).

The operation of the CPU 1 of FIG. 1 will be described with reference to the flowchart of FIG. In FIG. 2, it is assumed that a normal error log output request, an error log output request when an error occurs, or a mode change request is received from a routine (not shown). In step 201, it is determined whether or not a normal error log output request has been issued. In step 202, whether or not an error causing a failure in the operation of the computer system has occurred and an error log output request has been issued. It is determined whether or not there has been a mode change request made after checking the state.

When a normal error log output request is made, the flow advances to a cyclic mode in step 204.
That is, as shown in FIG. 3A, the error log files A and B have a fixed length, and when the error log file A becomes full of error logs, the error log file B is overwritten with the error log. When the error log file B becomes full with the error log, the error log file A is overwritten with the error log. In this case, since no error causing a failure in the operation of the computer system has occurred, the error log files A and B
It is not necessary to refer to the contents of the error log file when switching to and from.

If there is an error log output request when an error occurs, the flow advances to an automatic extension mode in step 205. For example, if logging is performed on the error log file B at this point, the error log file B is expanded as shown in FIG. At the same time, an error message is output to the output device 5 to notify the user. Further, it is determined whether or not the remaining capacity of the memory 3 is at a level that hinders output, and in that case, a warning message is output to the output device 5 to notify the user. Furthermore, it is determined whether or not the remaining capacity of the memory 3 has reached the output limit. In that case, a stop message is output to the output device 5 to notify the user. In this way, only when there is an error log output request when an error occurs, the remaining capacity of the memory is monitored, and the link between the occurrence of the error and the logging to the error log file is achieved.

If there is a mode change request, the flow advances to an automatic extension release mode in step 206. For example,
As shown in FIG. 3 (C), it returns the extended error log file B to the original fixed length.

[0011]

As described above, according to the present invention, it is not necessary to refer to the memory unless an error causing a problem in the computer system occurs. Further, the memory requires only a fixed amount of memory. Only when an error that could hinder the computer system occurs, the subsequent error logs can be logged as much as possible, and can be reset again, so the number of times the error log file is referenced by static control Can be reduced, and the number of times of monitoring the limit capacity of the memory in the dynamic control can be reduced. Further, it is possible to link the occurrence of an error with the error log file.
