Abstract

PURPOSE:To shorten the time required for analysis of the factor of a defect by adding the information showing the call nest situation of a routine to a work area together with the information to identify the transaction that caused the start of the routine. CONSTITUTION:A routine A receives a transaction 50 and nests with the routines B, C and D. In such a case, various identifiers are set at the head of each work area. Here a calling address A1 of a relevant routine is prepared together with a calling routine name A2, and the transaction series numbers A3. Thus the routine B is called by the routine A with the routines C and D called by the routines B and C respectively by said series of identifiers. Then it can be identified that the routine A is started by the reception of the transaction 50. As a result, a routine call nest corresponding to a due transaction can be identified out of a memory dump list. Then the defect analyzing time is shortened in case a trouble occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to work area management in a data processing system, and is particularly a work area management method suitable for early failure cause analysis at the time of abnormal termination.

[Conventional technology]

Traditionally, management information set when securing a work area includes:
Routine nest and transecutor identification information are not set on the work area. For this reason, it is difficult to identify transaction-compatible routines from the memory dump list, which takes time and effort when troubleshooting. Incidentally, a related patent of this type is JP-A-58-191054.

[Problem to be solved by the invention]

In the conventional work area management method, the work area management information is
Only information regarding the address and size of the work area was provided, and no consideration was given to information for identifying the routine that secured the work area. With this method, when a program terminates abnormally and the nesting of routines is complicated, it is difficult to identify the nesting status of the routines and the transaction number 1 from the memory dump list, and it is difficult to analyze the cause of the failure. There was a time when it took a lot of time and effort.

An object of the present invention is to easily identify the nesting status of routine calls and which transaction when a program terminates abnormally, thereby reducing the time required to analyze a failure.

[Means to solve the problem]

In the present invention, when a program dynamically allocates a work area,
At the beginning of the secured work area, an identifier consisting of the address of the caller, the name of the routine of the caller, and a playing card 2f1f serial number that identifies the transaction that triggered the activation of the routine is set. With this identifier, when a trouble occurs, it is possible to identify the nesting status of the routine and the transaction run that triggered the activation from the memory dump list when analyzing the trouble, thereby making it possible to shorten the time required to analyze the fault.

[Effect]

When a program terminates abnormally, the nesting status of the routine and information that can identify the transaction remain in the memory dump, making it possible to reduce the time required to analyze the cause of the failure.

〔Example〕 Embodiments of the present invention will be described below with reference to FIG.

(The structure and operation of the embodiment will be explained below) The transaction 50 is received by the routine A, and as shown in the figure, the urchin routine B1
If routine C1 is nested with routine D, each fla identifier is set at the beginning of each work area as shown in the figure. Here, A1 represents the calling source address of the routine, A2 represents the name of the caller routine, and A5 represents the serial number of the first transaction. From these series of identifiers, Routine B is called by Routine A, Routine C is called by Routine B Nicole Saleh, Routine D is called by Routine C, and Routine A is started upon receipt of transaction 50. can be identified.

Furthermore, since the serial number of the transaxis 1 in the work area of X is 49, it can be determined that this work area is not related to the routine nest activated by the current transaxis run 50.

In this way, the transaction-compatible routine call nest can be identified from the memory dump list, making it possible to shorten the analysis time for failures when trouble occurs.

〔Effect of the invention〕

According to the present invention, since information indicating the call nest status of the routine and information identifying the transaction that triggered the start of the routine exist in the work area, it is possible to identify the routine from the memory dump list in response to the transaction during trouble analysis. Since the nest can be grasped, the time required to analyze the cause of defects can be shortened.

Claims (1)

[Claims] 1. When dynamically allocating a work area with many nested routines, such as in an online program, the address of the caller, the name of the caller's routine, and the transaction in which the routine was called are displayed at the beginning of the work area. A work area management method characterized in that a work area is managed by setting an identifier consisting of a transaction serial number.
