Abstract

PURPOSE:To keep the contents of a trace area showing the processing process for the specific processing result by using a condition table which supplies the separating conditions of trace areas and separating the specific one of plural trace areas when the separating conditions are satisfied. CONSTITUTION:A trace means 2 writes successively the processing result obtained at a prescribed time point and the trace information on the control information into the trace areas 4 by the function of a program 1 and based on a trace step. A condition table 5 describes and stores the separating conditions that specify the areas 4 respectively. A separation means 3 compares the contents of the table 5 with the trace information and separates a specific area 4 out of plural areas 4 when the conditions, i.e., the contents of the table 5 are satisfied. Thus the trace information on the process reaching the specific processing result is never lost.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application) The present invention relates to a tracing method in an information processing system or a program maintenance system.

(Prior Art) Conventionally, in this type of information processing system, trace information has only been sequentially stored in one or more trace areas.

(Problems to be Solved by the Invention) In the above-mentioned six conventional tracing methods, when a program outputs a certain processing result, even if you later try to analyze the process that led to that processing result or the control state of the program, There is a drawback that the trace information generated by the execution of another program is written into the finite trace area, causing the trace information of the program to be lost.

An object of the present invention is to store trace information in a plurality of trace areas by a tracing means, compare the trace information with conditions for separating the trace area, and only when the trace information satisfies the above conditions, store the trace information in a plurality of trace areas. Eliminate the above drawback by separating one area identified from the trace area,
The object of the present invention is to provide a nine-trace method configured so that trace information is not lost.

(Means for Solving the Problems) The tracing method according to the present invention includes a plurality of tracing areas,
Preferably, the system is configured to include a tracing means, a condition table, and a separating means.

The plurality of trace areas are for storing program processing results and control information as trace information in chronological order at predetermined times.

The tracing means stores trace information in a plurality of trace areas.

The condition table is for specifying each of a plurality of trace areas and describing and storing the conditions for intentional disconnection.

The separation means compares and determines the contents of the condition table with the trace information, and when the conditions as the contents of the condition table are satisfied,
This is for separating a specific trace area from multiple trace areas.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 5 is an explanatory diagram showing the contents of a condition table S of separation conditions used in the separation means 3 shown in FIG. In FIG. 5, condition table 5 is composed of processing results 1 to 8.

Next, the operation of the present invention will be explained with reference to the drawings.

Through the operation of the program 1, the trace means 2 sequentially writes processing results and control information trace information at predetermined times into the trace area 4 according to the trace steps. Used in the distribution of -da...

Next, a step of starting the separating means 3 is entered, and the separating means 3 is activated according to FIG. The separation means 3 is @
According to FIG. 8, in the condition determination step, the processing result of the trace information that is not written at the current time and the plurality of processing results stored in the condition table 5 of FIG. 5 are sequentially compared and determined. If any of the conditions is satisfied, one of regions a to d of the trace region 4 at that time is separated.

Assuming that area C has been separated, areas a, b,
Tracing is repeated according to d, a, b, d, *-, and area C is not used.

(Effects of the Invention) As described above, the present invention determines the processing result of trace information using a condition table that provides conditions for separating trace areas, and when the separation conditions are satisfied, it identifies one of a plurality of trace areas. By separating one of them, there is an effect that the contents of the trace area indicating the process of a specific processing result output when the program is executed can be left.

Therefore, since the contents of the trace area can be analyzed later, there is an effect that the maintainability of the information processing system, programs, etc. can be improved.
