Abstract

PURPOSE:To facilitate new registration and addition as well without necessity for complicated programming by registering a fault analyzing means on a data base as a procedure using simple language. CONSTITUTION:This system is provided with a fault analyzing means 1I to analyze a fault, information collecting means 1J to collect information, and procedure registering means 1H to make the fault analyzing means 1I and the information collecting means 1J into a procedure and to register this procedure on the data base while defining the simple language enabling a description to instruct the execution of information collection/fault analysis from fault log information IC and a description to instruct the collection/fault analysis of timely required information by being activated under the environment of reproducing a program generating the fault. Then, a fault analysis procedure 1A is prepared by describing a series of fault analyzing means 1I based on the use of the simple language and registered on a procedure storage data base 1B by using the procedure registering means 1H.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program failure analysis method.

[0002]

2. Description of the Related Art Conventional program failure analysis is mainly performed by a skilled person or manually with reference to a manual, and if the analysis of the program is difficult due to the nature of the program, an analysis means is incorporated. It was done by creating a failure analysis program and using this failure analysis program.

FIG. 2 is a flow chart showing an example using a conventional failure analysis program.

First, the already known failure analysis means is described using a high-level language, and the failure analysis program 2
Create K.

Then, the failure analysis program 2K is started,
The failure log information 2C is analyzed. If the analysis is successful, the failure analysis result 2D is output and the processing is terminated. However, if the analysis cannot be performed, the subsequent work, that is, information collection and failure analysis, are all manual work.

When collecting information, the necessary information is first obtained from the fault log information 2C, but when it is insufficient, the faulty program itself is modified to obtain trace information and dump information. Become.

Finally, the failure analysis program 2K is modified to create a new failure analysis means.

[0008]

The above-mentioned conventional program failure analysis method has the following drawbacks.

(1) Manual Analysis Only members with the ability to perform analysis can perform analysis.

(2) When using a failure analysis program for analysis It is necessary to create a complicated logic when programming the analysis means.

When there are a plurality of programs to be analyzed, it is necessary to prepare a failure analysis program corresponding to each of them.

When the built-in analysis means cannot analyze,
In order to perform manual analysis, it is necessary to prepare another tool to collect necessary information from the failure log information, and further to correct the program in which the failure has occurred.

[0013]

According to a program failure analysis method of the present invention, failure analysis means for analyzing a failure, information collection means for collecting information, and information collection / fault analysis from failure log information are instructed. And the failure analysis means are defined, and a simple language capable of instructing to start in an environment for reproducing the program in which the failure has occurred and to perform necessary information collection / failure analysis in a timely manner is defined. And a procedure registration means for converting the information collecting means into a procedure and registering the procedure in a database.

[0014]

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

FIG. 1 is a flow chart showing an embodiment of the present invention.

If what kind of analysis is to be performed based on what information is included in the failure log information, or if there is insufficient information necessary for analysis in the failure log information, start the program in which the failure has occurred. Failure analysis procedure 1A in which a series of failure analysis means for dynamically collecting information based on the use of a simple language is created, and procedure registration means 1H is created.
Is used to register in the procedure storage database 1B. At this time, when there are a plurality of failure analysis means, a corresponding failure analysis procedure is created and registered.

Next, failure analysis is performed using the failure analysis means 1I. The failure analysis means 1I is the procedure storage database 1
The failure analysis procedure registered in B is sequentially taken out, and the failure analysis processing is repeated until the failure can be correctly analyzed or the failure analysis procedure is exhausted.

As a result of the analysis based on the extracted failure analysis procedure, if the analysis is successful, the failure analysis result 1D is output and the processing ends, but if it is not possible, the next failure analysis procedure registered. The removal process is continued. If all the failure analysis procedures cannot be used for analysis, it is determined that analysis is not possible and the processing ends.

When the analysis becomes impossible, the analysis is performed manually, so that the information collecting work is performed first. For this reason, how to collect information necessary for analysis from the failure log information 1C, or if necessary information does not exist in the failure log information 1C, start up the program in which the failure has occurred and collect it. As a series of processes, the information collecting means is proceduralized based on the specification of the simple language to create the information collecting procedure 1E, and is registered in the procedure storing database 1B using the procedure registering means 1H.

Next, the information collection means 1J is used to acquire the information collection result 1F, and the failure analysis is performed manually. These series of operations are repeated until the analysis is completed, and when the analysis is completed, the failure analysis means obtained in the course of this analysis operation is created as a failure analysis procedure 1G and additionally registered by the procedure registration means 1H.

[0021]

As described above, according to the present invention, the failure analysis means is registered in the database as a procedure by using a simple language, so that complicated programming is not required and new registration and addition are easy. You can

Further, even if there are a plurality of analysis target programs, if a corresponding database is prepared, the analysis can be performed simply by changing the database.

Further, since the failure analysis procedure and the information collection procedure can be described as instructing to dynamically start the analysis target program itself to perform the information collection / fault analysis as described above, the failure collection is finally performed. There is no need to change the analysis target program.
