Abstract

PURPOSE:To refers to trace information right before fault occurrence in an edited state and to decrease the operation man-hours for fault cause analysis by outputting information in a trace information area on a document when program abnormality which is not set in a trace file occurs. CONSTITUTION:In off-line mode, a user indicates the output of trace information, obtained in off-line mode, to a trace information output part 7. A file editing output part 71 inputs the information of the trace file 3 according to the indication from the user and outputs the trace information on the document. Further, a memory information editing output part 72 inputs the information of a memory information saving file 8 according to an input indication from a console 1 and outputs the trace information on a document. Consequently, the trace information right before the fault occurrence can be referred to in the edited state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trace information output processing method, and more particularly to a trace information output processing method for outputting trace information immediately before a program abnormality occurs in an online system.

[0002]

2. Description of the Related Art In recent years, information processing apparatuses have been increasingly used in higher and more complex system environments, and the number of man-hours required for maintenance and operation of the information processing apparatuses has increased. For this reason, the online processing trace information collecting function is supported especially for the work that requires quick and accurate response such as cause analysis when a system failure occurs.

In the conventional trace information output processing method, the trace file provided on the external storage device is triggered by the fact that the trace information temporary save area in the main memory is filled with the trace information collected during the online processing. Then, the data is sequentially stored. When the online processing ends normally, the information up to the end is stored in the trace file even if the trace information temporary save area is not full of trace information. Therefore, the latest trace information collected while online can be referred to by outputting the trace information stored in the trace file in the form of online. However, if the system goes down during online processing, the trace information collected in the trace information temporary save area will be lost at this point. With the conventional trace information output processing method, the trace information already stored in the trace file can be referenced. However, the latest trace information immediately before the failure cannot be referenced.

[0004]

The above-mentioned conventional trace information output processing method has a problem that the trace information immediately before the occurrence of a failure cannot be referred from the trace file. In order to remedy this, it is conceivable to output and refer to all the memory information saved in the external storage device, but in this case only the trace information cannot be edited and output, so actual tracing is extremely difficult. There is another problem.

It is an object of the present invention to provide a trace information output processing method which makes it possible to refer to the trace information immediately before the occurrence of a failure in an edited state and reduce the number of man-hours for analyzing the cause of the failure.

[0006]

A trace information output processing method according to the present invention is a trace information output processing method for an online system having a function of sequentially acquiring trace information including parameter information in a memory during online processing. A trace information acquisition control unit that acquires the trace information according to an instruction input from and stores it in a trace information area provided in the memory, and write the trace information set in the trace information area to an externally provided trace file. A memory management unit to control, an all-memory output unit that writes all memory information stored in the memory to an externally provided memory information save file when the program abnormality detection unit detects a program abnormality, and the memory information Equipped with a memory information edit output unit that edits and outputs all memory information written in the save file The Rukoto a configuration for editing the trace information acquired by program error occurred immediately before the required detection time of the failure cause analysis of the abnormal output of the program.

[0007]

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

FIG. 1 is a block diagram of an embodiment of the present invention.

The trace information acquisition control unit 2 follows the trace information acquisition instruction input from the console 1 and stores the trace information being processed online in the trace information area 5 in the memory 5.
Get to 1. The memory management unit 4 outputs the trace information in the trace information area 51 to the trace file 3 provided outside when the trace information area 51 is filled with the trace information. When a program abnormality occurs, the all-memory output unit 6 receives an instruction from the program abnormality detection unit 9 that is provided in advance, and the memory 5 outputs
The output processing of all the information of (1) to the memory information save file 8 is performed.

When offline, the user instructs the trace information output unit 7 to output the trace information acquired while offline. The file edit / output unit 71 performs a trace information form output process using the information of the trace file as input information according to the instruction from the user. The memory information edit output unit 72 follows the instruction input from the console 1,
A form output process of trace information is performed using the information in the memory information save file 8 as input information. As a result, it becomes possible to refer to the trace information immediately before the occurrence of the failure in the edited state.

Next, the operation will be described.

FIG. 2 is an explanatory diagram for explaining the operation of the trace information search processing in the memory information save file.

First, the trace information save area management information address 21 which is managed as a fixed position is searched by using the in-memory relative address as a key. Next, the trace information save area management information 22 is searched based on the searched relative address B in the memory, and the trace information save area is further searched based on the searched relative address C in the memory of the trace information save area address 221. Search for 23.

At the time of the latest trace information output processing, the trace information of the maximum trace information save area length 222 from the beginning of the retrieved trace information save area 23 is the object of form output.

[0015]

As described above, according to the present invention, since the information in the trace information area at the time of the occurrence of a program error not set in the trace file can be output as a form, the trace information immediately before the occurrence of the failure is referred to in the edited state. Therefore, there is an effect that the man-hours for failure cause analysis can be reduced.
