DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of outputting a failure analysis file output due to a failure during execution of a user program and a method using the same.

[0002]

2. Description of the Related Art Conventionally, when any trouble occurs during execution of a user program, a computer outputs a file for analyzing the trouble. This failure analysis file is usually output for each area of the program. For example, the failure analysis file is output for each area such as a text area, a data area, and a stack area.

[0003]

However, while the failure analysis file is being output, the computer cannot execute new processing. Specifically, a computer terminal cannot be used. In particular, F
When a failure occurs in a program having a large data area (for example, an area of about several GB (gigabytes)) like ORTRAN, it takes a long time until the output of the failure analysis file is completed. Therefore, there is a problem that the terminal operation must be waited until the output of the failure analysis file is completed.

There is also a method of forcibly interrupting the output of a failure analysis file halfway. For example, a document: "Japanese Patent Laid-Open No. 5-120242" describes that data processing being executed is forcibly interrupted. However, when the output of the file is forcibly interrupted, it is difficult to specify the file that has not been output due to the interruption. For example, information about the data section, the stack section, or the like may not be output due to the interruption. Then, information on a portion of the failure analysis file that has not been output cannot be referred to at the time of failure analysis.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has an object to provide a failure analysis file output method capable of shortening a waiting time when outputting a failure analysis file.
It is an object of the present invention to provide a storage medium storing a program for a failure analysis file output method and a failure analysis file output method.

[0006]

[Means for Solving the Problems] (Failure Analysis File Output Method) In order to achieve this object, according to the failure analysis file output method of the present invention, when outputting a failure analysis file, 1 MB of the failure analysis file is output. Each time, it is determined whether a signal instructing the interruption of the output of the failure analysis file has been received.If a signal is received, the output of the failure analysis file is interrupted.If no signal is received, the failure analysis file is further added. There is a method of outputting 1 MB .

As described above, according to the failure analysis file output method of the present invention, the presence / absence of an instruction to interrupt the output is confirmed each time a failure analysis file is output in a fixed amount. Then, if the signal of the interruption instruction is received, the output is interrupted. Therefore, according to the present invention, it is possible to reduce the waiting time when outputting the failure analysis file.

More specifically, a certain amount of file output is 1M
B. I / O page size unit is usually 1
MB. Therefore, if a file is output in units of 1 MB, the file can be output efficiently with I / O.

(Failure Analysis File Output Method) According to the failure analysis file output method of the present invention, a reception processing unit for receiving a signal instructing interruption of the output of the failure analysis file, and outputting a fixed amount of the failure analysis file Each time the reception processing unit inquires whether the signal has been received, the reception processing unit interrupts the output of the failure analysis file when the signal is received, and the reception processing unit does not receive the signal. And an output processing unit for outputting the next fixed amount of the failure analysis file.

As described above, according to the failure analysis file output method of the present invention, the output processing method confirms whether or not there is an instruction to interrupt the output to the reception processing unit 12 every time a predetermined amount of the failure analysis file is output. Then, when the reception processing unit 12 has received the signal of the interruption instruction, the output is interrupted. Therefore, according to the present invention, it is possible to reduce the waiting time when outputting the failure analysis file.

In practicing the present invention, it is preferable that a certain amount of file output be 1 MB. If the fixed amount is 1 MB, for example, it is possible to output efficiently in page size units.

In the failure analysis file output method according to the present invention, preferably, the reception processing unit sets a flag when a signal is received, and the output processing unit performs
If the flag is set, it is determined that the signal is received. If the flag is not set, it is determined that the signal is not received.

As described above, if the reception processing unit sets the flag indicating signal reception, the output processing unit can determine the presence / absence of signal reception by confirming the presence / absence of the flag.

In the failure analysis file output method according to the present invention, preferably, a transmission processing unit for transmitting a signal to the reception processing unit may be provided.

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that the drawings to be referred to show the size of each component so that the present invention can be understood,
It merely shows the shape and arrangement.
Therefore, the present invention is not limited only to the illustrated example.

<First Embodiment> First, the configuration of a failure analysis file output device 100 for realizing the failure analysis file output method of the first embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram for explaining the configuration of the failure analysis file output device 100 according to the first embodiment. This failure analysis file output method 1
00 is realized by an OS of a computer (also referred to as a “central processing method”, “processor” or “data processing method”).

As shown in FIG. 1, the failure analysis file output method 100 includes an output processing unit 10 and a reception processing unit 12. The reception processing unit 12 is a part that receives a signal instructing interruption of the output of the failure analysis file. In this embodiment, an operator inputs a signal from outside the system 100.

The output processing unit 10 outputs the failure analysis file by dividing it into fixed amounts. In this embodiment, as a fixed amount, a file is output in units of 1 MB. If output is performed in units of 1 MB, output can be performed in units of page size. Then, the output processing unit 10 inquires of the reception processing unit 12 whether or not a signal has been received every time the failure analysis file is output by 1 MB.

When the reception processing unit 12 receives a signal, the output of the failure analysis file is interrupted. on the other hand,
When the reception processing unit 12 does not receive a signal, the failure analysis file is output in the following fixed amount. Then, after outputting a certain amount, it is confirmed again whether or not a signal has been received.

Next, the operation of the failure analysis file output method 100, that is, an example of the failure analysis file output method of the present invention will be described with reference to FIG. FIG.
5 is a flowchart for explaining a failure analysis file output method according to the embodiment. When the failure analysis file output method 100 outputs a file, the output processing method 10 first checks whether there is data to be output as a failure analysis file (S1 in FIG. 2). When there is no data, the output processing method 10 ends the processing. On the other hand, if there is data, the output processing method 10
Executes the following process of S2.

Next, the output processing method 10 outputs the failure analysis file for 1 MB (S2 in FIG. 2).

Next, the output processing system 10 includes the reception processing unit 1
2 is inquired as to whether a signal has been received (S3 in FIG. 2).

When the reception processing unit 12 receives a signal (in the case of "YES"), the output of the failure analysis file is interrupted, and the processing ends. As an example of the termination, for example, the information amount of the failure analysis file is 200 MB.
In such a case, the SIGINT signal may be sent to the reception processing unit 12 when the operator presses the delete key on the keyboard when the file is output at 50 MB, for example. In this case, the output processing is interrupted.

On the other hand, if the reception processing unit 12 does not receive a signal ("NO"), the process returns to S1.
Then, if there is data to be output, the failure analysis file is further output by 1 MB.

As described above, the failure analysis file has a size of 1 MB.
Each time an output is made, the presence or absence of an output interruption instruction is checked. Then, if the signal of the interruption instruction is received, the output is interrupted. Therefore, it is possible to reduce the waiting time when outputting the failure analysis file. In addition, since the file is output in units of 1 MB, it is possible to specify a file that has not been output when the output is interrupted.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart for explaining the processing of the reception processing unit 12. In this embodiment, the reception processing unit 12 shown in FIG. 1 confirms whether or not a signal has been received (S4 in FIG. 3). When a signal is received, a flag is set (S4 in FIG. 3).

The output processing unit 10 determines that a signal has been received if a flag is set in the reception processing unit 12 at the time of inquiring about the processing in S3 in FIG. On the other hand, if the flag is not set, it is determined that the signal is not received.

As described above, when the reception processing unit 12 sets the flag indicating the signal reception, the output processing unit 10 determines the presence / absence of the signal reception by confirming the presence / absence of the flag of the reception processing unit 12. Can be.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 4 shows a failure analysis file output method 1 according to the third embodiment.
FIG. 2 is a functional block diagram used for describing a configuration of No. 02. The configuration of the failure analysis file output method 102 according to the present invention is the same as the output method 100 according to the first embodiment except that the transmission processing unit 14 that transmits a signal instructing the interruption to the reception processing unit 12 is provided. The configuration is the same as

Then, for example, the operator operates the transmission processing unit 1
4 transmits a signal, the reception processing unit 12 that has received this signal sets a flag. Then, the output of the file is interrupted as in the second embodiment.

In the above-described embodiment, an example in which the present invention is configured under specific conditions has been described. However, the present invention can be variously modified. For example, in the above-described embodiment, an example has been described in which a file is divided and output in units of 1 MB. However, in the present invention, the unit in which a file is divided need not be limited to 1 MB.

[0032]

As described in detail above, according to the failure analysis file output method of the present invention, the presence or absence of an instruction to interrupt the output is confirmed each time a failure analysis file is output by 1 MB . Then, if the signal of the interruption instruction is received, the output is interrupted. Therefore, according to the present invention,
The waiting time at the time of outputting the failure analysis file can be reduced. Further, according to the failure analysis file output method of the present invention, the output processing method is such that the failure analysis file is 1 MB.
