Abstract

PURPOSE:To shorten the damp analyzing time for users and to secure high accuracy of said analyzing job by omitting a converting job of the damp data of a memory image style obtained by a user into an expression style of a description level of a source program. CONSTITUTION:A data name acquiring part 3 receives control from an operation system 6 and acquires the name of the data to be compiled through a terminal equipment 7 or an SYSIN file 8. Then the damp data equivalent to the length of a data area out of a storing file 11 for memory image type damp data through an address of executing mode among those damp data. This extracted damp data is compiled into an expression style of a source program description level in accordance with the style of said damp data. Thus it is possible to regard the contents of a data area as an expression style of the source program description level. In such a way, the damp analyzing time is shortened for users together with omission of converting errors caused by manual operations.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to program debugging work in an information processing system, and particularly to analysis work of abort dump data at the time of program abort.

(Prior Art) Conventionally, dump data in a memory image format collected at the time of program abort has been so anonymous that each byte is simply edited into a hexadecimal representation and a character representation.

(Problems to be Solved by the Invention) In the conventional editing method described above, the user merely converts the contents of memory image format dump data into a source program description level expression format. Therefore, there are problems in that dump analysis takes too much time and also lacks accuracy due to conversion errors.

An object of the present invention is to eliminate the above-mentioned drawbacks by eliminating the sound of the user converting dump data in memory image format to an expression format at the source program description level, thereby reducing the time required for the user to perform dump analysis work. It is also an object of the present invention to provide an abort dump data symbol editing method that provides accuracy to the work.

(Means for Solving the Problems) The abort dump data symbol collection method according to the present invention includes a file storage means, a data name acquisition section, an editing processing section, an editing result output section, and a main control section. This is just a reminder.

The file storage means is for storing a program name table storage file, a compile time/runtime address conversion table storage file, and a memory image format dump data storage file used for abort dump analysis processing of the information processing system. It is something.

The data name acquisition unit is used to inform the user of the data name of the data area to be edited.

The editing processing section is for editing the memory image format dump data into an expression format at the source program description level based on the data attributes of the acquired data name.

The editing result output section is for outputting the editing results.

The main control unit is for controlling acquisition, editing, and output operations.

[lol Example]

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the abort dump data symbol editing method according to the present invention, and the second part is a flowchart showing the operation of the present invention shown in FIG.

In FIG. 1, 1 is the main part of the abort dump data symbol editing, 2 is the main control part, 3 is the data name acquisition part, 4 is the editing processing part, 5 is the editing result output part, 6 is the operation system, and 7 is the terminal. Device.

8 is a 5YSIN file, 9 is a program name table storage file, %1O is a compile time/runtime address conversion file storage file, 11 is a memory image format dump data storage file, and 12 is a 5YSOUT file.

As shown in FIG. 1, the abort dump data symbol editing method according to the present invention includes a user's instruction, an operation system 6, a data name acquisition section 3, an editing processing section. 4 and an editing result output unit 5, and uses a plurality of types of files 9 to 1lt.

That is, the program name table storage file 9 stores the program name table output from the compiler in advance, and the compile-time/run-time address conversion table storage file 10 stores the address conversion table sent from the linker. 6, and the memory image format dump data storage file 11 stores memory image format dump data collected at the time of program abort.

The data name acquisition unit 3 receives from the user, using the terminal device 7 or the 5YSIN file 8, the data name of the area of memory image dump data that is desired to be edited into an expression format at the source program description level. The editing processing unit 4 extracts a name table entry from the program name table storage file 9 using the data name as a key, and then extracts the data attribute and compile-time address stored in the entry.

Furthermore, using the compile time address as a key, the corresponding runtime address is extracted from the compile time/runtime address conversion table storage file 10.

Memory image format dump data storage file 11 for the data area required in the data attributes from the execution address
, edit the dump data into an expression format at the source program description level according to the data format in the data attributes (character format, packed decimal format, floating point format, etc.), and add the data name to this. The editing result is generated with the data structure added.

The editing result output s5 outputs the editing result obtained in this way to the terminal device 7 or the SYSOUT file 12.Next, referring to FIG. 1 and FIG. 2, the abort dump data symbol collection method 1 is executed. The operation will be explained briefly.

When the control 111 is received from the operation system 6, the
1) The data name acquisition unit 3 sends a message to the terminal device 7 or 5.
Obtain the data name to be edited through the YSIN file 8. Then, (11) using the data name as a key, the program name table storage file 9 is loaded with the data attribute of the data name and the compile-time address. Further, in the (111)th step, a run-time address is read from the compile-time/run-time address conversion table storage file 10 using the compile-time address as a key. Part (I■),
From the memory image format dump data storage file 11, extract the dump data of only the data area length valve from the runtime address in the dump data, and (V) combine the above data into the data format to create an expression format at the source program description level. Edit to. Furthermore, (■1), the editing results from the editing result output unit 5 are transferred to the terminal device 7 or 5YSOU.
Output to T-file 12.

After this, control is returned to the operating system 6.

(Effects of the Invention) As explained above, the present invention is configured so that when outputting dump data in memory image format during dump analysis work, the user only needs to specify the data name. Since the contents of the area can be viewed in an expression format at the source program description level, the user's dump analysis work time can be reduced and accuracy can be achieved without manual conversion errors.
