Abstract

PURPOSE:To acquire the information with high reliability and also to reduce the data collecting manhour of a user by outputting the information obtained right after the fault of an application program occurred to a file at the occur rence of the fault. CONSTITUTION:This system includes a incorrect data detecting means 11 which produces a signal showing the occurrence of the incorrect data when an application program has the incorrect data during its operation due to the signal function of a UNIX to cause the abnormal end and an OS receives the incorrect data, and a recovery processing means 12 which carries out the processing according to the recovery processing routine to close a file when the application program receives the signal of the UNIX. Then, an analysis data collecting means 13 receives the result of the means 12 to carry out the processing based on the analysis data collection system execution routine and also outputs the file of the necessary information. In such constitution, the analysis data are collected after the end of the fault of the application program.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analysis data collection system for abnormal termination of application software,
In particular, an operating system developed and licensed by UNIX (Unix International Laboratories), which is one of the operating systems.
(Represented by "NIX") related to the analysis data collection system at the time of abnormal termination that outputs necessary information immediately after abnormal termination of the application software used above to a file.

[0002]

2. Description of the Related Art A conventional analysis data collection system for abnormal termination of application software has a form in which necessary information is manually collected by utilizing a utility or the like. However, when the utility is used, the timing of the program run may be different due to its structure, and the location of the abnormal end may be different.

[0003]

The conventional analysis data collection system at the time of abnormal termination as described above collects information by hand, and therefore cannot collect data without knowledge of UNIX commands and utilities, for example. It was In addition, the most important thing is that the collected information is information immediately after the occurrence of an abnormality, which is not 100% guaranteed.

[0004]

According to the analysis data collection system for abnormal termination of application software of the present invention, when abnormal data is generated in the application program and the application program is abnormally terminated while the application program is operating by a UNIX signal function. An illegal data detection means for issuing a signal for generation of illegal data when the OS receives the illegal data, and a recovery processing means for executing processing by a recovery processing routine when the application program receives the signal and performing file closing processing In the analysis data collection system after abnormal termination, the result of the recovery processing means according to the application program is received, processing is performed by the analysis data collection system execution routine, and a file of necessary information is output. Configured with an analysis data collecting means to terminate the process by performing the process.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view showing an embodiment of the present invention, and FIG. 2 is an explanatory view showing an execution part of this embodiment.

First, the function of FIG. 1 uses the UNIX signal (SIGNAL) function in the application program 21 for which forced termination / instruction disregard or designation of jumping to a function is designated to perform interrupt processing. Assuming that you are doing.

Therefore, U is used as the illegal data detecting means 11.
When invalid data is generated in the application program (step 1) while the application program on the UNIX is being developed using the signal function, the invalid data is checked in the signal function, and the OS
22 issues a signal (step 3). Next, as the recovery processing means 12, when the application program receives the cancellation by the above-mentioned signal invention instruction (step 4), the application program interrupts the processing,
Recovery processing routine created by the developer (EXCEP
(TION routine) to execute this (step 5) and forcibly terminate the process (step 6).
This is a recovery process that is often used in normal application programs.

In this embodiment, the analysis data collecting means 13 using this function outputs the analysis data to a file. That is, since the UNIX signal function cannot call a plurality of subroutines, an analysis data collection system execution routine (processing for outputting necessary information to a file) is called in the recovery processing routine in the form of a child subroutine and executed (steps 7 and 8). ) Do. After that, process termination processing is performed (step 9). As a result, an abnormality occurs on the application program side, and interrupt processing is executed in the signal corresponding function. That is, the application program is terminated after performing the recovery process and newly collecting the analysis data.

[0010]

As described above, according to the present invention, by outputting the information immediately after the occurrence of the abnormality of the application program to the file when the abnormality occurs, highly reliable information can be obtained and the number of man-hours for collecting the data of the user can be reduced. Therefore, it is considered that the more reliable the information is from the developer, the better the pursuit of the cause of the abnormality. In addition, the timing of the program itself is not disturbed unlike the externally activated debugger.
