Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system which operates according to a multi-programming processing system in which a large number of programs are simultaneously executed.
The present invention relates to a message classification method and apparatus for classifying messages output to kernels or the like into predetermined categories, and dividing and outputting the messages for each category.

[0002]

2. Description of the Related Art Conventionally, multi-programming processing (also referred to as multi-programming processing) in which a plurality of programs are executed simultaneously by one computer has been performed for the purpose of effectively using computer resources without waste. Each program is processed in parallel using the execution interval of the computer instruction.

[0003] As a method of processing each program simultaneously and in parallel, for example, a method using a processing time difference of a separate control system such as an arithmetic processing and an input / output processing, or a time division (time) in which a fixed time piece is allocated to each program. share) and a method based on an equal service.

The former utilizes the fact that the speed of an input / output device is extremely slow as compared with the processing speed of a central processing unit (CPU). That is, the central processing unit is in a waiting state while an input / output operation (access to an external storage device, an external memory, or the like) is being performed. Therefore, a plurality of storage areas (sections) for processing programs are prepared, and a plurality of programs are stored in each section, and while one program is waiting for input / output, another program is stored. In this method, each program is processed in parallel by executing the program.

[0005] The latter is, for example, a form of multi-programming technique, such as a time-sharing system (TSS), in which computers are shared.

Incidentally, in such a multi-programming process, that is, in a computer system in which a large number of programs are executed simultaneously and in parallel and each program outputs an operation status or the like on a console, a console (system console or the like) is used. Various messages are output and displayed in a mixed manner, and it is difficult to easily understand which message is output from which program.

When a large amount of messages are output from a large number of programs, the messages cannot be displayed on the console. For example, the messages are output to an external storage device or the like as a log file, and this log is later output. It was necessary to check the files to understand the operation status of the program. Further, at this time, a large amount of various messages are output to the log file, and when searching for a message of a specific event (for example, an error message), the entire log file is visually checked to confirm a desired message. Confirmation work was not easy.

In order to solve such a problem, that is, as a technique for determining from which program an output message is output,
Japanese Unexamined Patent Publication No. 7-239827 discloses a conventional technique.

Japanese Patent Application Laid-Open No. 7-239827 discloses that when a job (program) is input,
Jobs are classified in advance, and when a job (program) outputs a message, an attribute matching the class is assigned to the job by an identification attribute assigning unit, and a message display area is displayed separately for each assigned attribute. , A message discrimination method is disclosed.

[0010]

However, according to the above-mentioned prior art, it is necessary to specify a job class when submitting a job (program), and an execution management means for performing this is required. In addition, an identification attribute assigning means is required to assign an attribute according to the class.

However, in general, in the field of use of the present invention, a management function for controlling program startup (task and memory management) and input / output is performed by an operating system (OS) of the system.
In order to realize the above-mentioned conventional message discrimination method, it is necessary to prepare an operating system incorporating the functions (execution management means and identification attribute giving means).
When such an operating system is used for a computer system, there is a problem (defect) that the system lacks versatility.

Further, the operating system is not of a nature that can be easily modified by the user in order to provide the above functions even if the above functions are not provided. Therefore, the operating system originally has the above functions. Otherwise, there is a problem (defect) that it is difficult to realize the above-described conventional message discrimination method.

Accordingly, an object of the present invention is to provide a method for setting each program without setting a job class in advance at the time of submitting a job (program) as described in the prior art or adding an attribute when outputting a message. Various information included in the message output via the OS is
It is an object of the present invention to provide a message classification method and apparatus which can classify messages into a predetermined category and display them separately for each category so that a message relating to a specific event can be easily searched for.

[0014]

In order to achieve the above object, the present invention relates to a computer system which operates according to a multi-programming processing system in which a large number of programs are executed at the same time. A message log file that stores a message log as a log file, a message reading unit that sequentially reads message records recorded in the message log file, and a message record from each of the programs read by the message reading unit. Message classification means for classifying the message records into predetermined categories based on information included in the message records, extracting and outputting the message information included in the message records, and A category management means for assigning a category number to the category to which the message record belongs, which is classified by the message classification means, and managing and storing the message records classified by the message classification means in association with the category number; and The message information output from the classification means

And display means for displaying and outputting in an appropriate state.

Further, the present invention operates according to a multi-programming processing system in which a large number of programs are executed at the same time, stores message records output by the programs in an external storage device or the like, and stores the message records in the stored message records. A computer system for classifying the message records into predetermined categories using information included in the external storage device, extracting the message information included in the message records for each of the categories, and displaying the message information separately on a display means. The read message records are sequentially read, the message records from the read programs are analyzed, and the message records are classified into predetermined categories based on information included in the message records. Classification A category number is assigned to the specified category by a predetermined method, the message record and the category number are managed and stored in association with each other, the message information included in the message record is extracted, and the message information is extracted. And assigning a category number corresponding to the message record, and outputting the message information to a display means in a recognizable state based on the category number assigned to the message information. It is.

According to the present invention, when a large number of tasks (including different tasks having the same task name) are simultaneously operating on a computer system, various tasks output from the tasks (via the OS) are provided. Message records are temporarily stored in a log file, the log file is read as needed, the read message records are classified into predetermined categories, and messages are output to different display areas for each category. Therefore, the target information (situation) can be quickly grasped by checking only a message group of a necessary category without checking all output messages.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a message classification device according to the present invention.

The message classification device of the present invention shown in FIG. 1 includes an OS (Operating System) 1 which resides in a main memory of a central processing control unit (not shown) and controls a computer system, and a task which is a program operating on the OS 1. 1 to task-n (n is an integer of 2 or more);
A console 7 for displaying various messages output from the OS 1; a message log file 2 for logging and storing various messages output from the OS 1; and a message reading unit 3 for reading a file logged from the message log file 2 A message classifying unit 4 for classifying the messages read by the message reading unit 3 into predetermined categories, a category management table 6 for managing the category of each message classified by the message classifying unit 4, The result output unit 5 displays messages classified into categories on the console 7.

OS1, which is an operating system for controlling the computer system, includes tasks-1 to tasks-
n (n is an integer of 2 or more) is controlled. Task-1 to task-n are programs operating on the OS1, and each program outputs a predetermined message each time an event occurs. For example, when a program (hereinafter, also referred to as a task) detects an error, an error message is output.

Each message output request from Task-1 to Task-n is output to the OS 1 (kernel managing tasks, memory, input / output, etc.) and is sent to the console 7 according to the message output request from each task. A message is displayed. Note that the message display output performed by the OS 1 at this time is not a job class or information such as an attribute corresponding to the job class as described in JP-A-7-239827, but a normal method (OS Is a message display output processed and output according to the method normally included in the present invention.

At this time, the OS 1 simultaneously operates the console 7
Is output to a message log file 2 which is an external storage device. As a result, all messages output by task-1 to task-n are temporarily stored in the message log file 2.

Generally, when a message output request from a task is processed by an operating system, the output format of the message is determined, and the time, the task name, and the task are specified by the operating system to control the task. Task identification number (hereafter,
Task ID). In the present embodiment, it is assumed that a message is output in a format as shown in FIG. 2 (hereinafter, also referred to as a message record).

FIG. 2 is a diagram showing an example of an output format of a message record output by the operating system.

In FIG. 2, the time at which the message record was output from the OS 1 to the message log file 2 is written at time 21, and the name of the task that output the message output request to the OS 1 is written in the task name area 22. Is written in the task ID area 23, and the task that outputs the message output request to the OS 1 is set to O.
A task number managed by the OS 1 is written for identification in S 1, and the content of the message is written in the message area 24.

Accordingly, the message log file 2 after each task has been executed contains a message from the OS 1 based on the output request output from each task to the OS 1, ie, a message in the format shown in FIG. Records will be recorded in large quantities.

The operator inputs an unillustrated input at an arbitrary time, such as when the execution of a plurality of programs is completed, when the execution of a part of the plurality of programs is completed, or when the execution of a predetermined program is completed. By operating the means, the message reading unit 3 is started. The activated message reading unit 3 sequentially reads out the message records from the OS 1 stored in the message log file 2 line by line and supplies the message records to the message classification unit 4.

The message classifying unit 4 receives the message records from the message reading unit 3, and classifies the received message records into predetermined categories. Here, an example in which tasks are classified for each task will be described in detail below.

When classifying messages for each task, the simplest method is to classify messages based on task name information. At this time, it is important to keep in mind that a plurality of identical task names must be considered. This is the case when the task having the task is being executed. In other words, if we simply categorize by task name,
These are all classified as one category. Therefore, in order to avoid this, for example, a task ID which is a task identification number managed by the OS 1 is used, and the same task name is treated as a different category depending on the difference in the task ID.

FIG. 3 shows a description format (management table) of the category management table 6 of FIG. 1 in the present embodiment.
FIG. 4 is a diagram showing an example of the above.

As shown in FIG. 3A, the category management table 6 includes, for example, a task name area 31 and a task I
The classification of the category is managed by associating the two pieces of information of the D area 32 with a category number area 33. First, the category management table 6 contains
This is an empty state in which nothing is registered, and every time the message classification unit 4 analyzes a message record and finds a message record of a new task, this table is added to and created in the category management table 6. This procedure will be described below.

First, the message classifying unit 4 receives one line (one record) first received from the message reading unit 3.
, The task name and the task ID are extracted from the message record and registered in the category management table 6. At this time, for example, “0” is assigned as the category number corresponding to the first task. The message classifying unit 4 then associates the message received from the message reading unit 3 (message information extracted from the message record, the same applies hereinafter) with the category number (here, “0”) associated with the category management table 6. ) Is supplied to the result output unit 5.

Similarly, the message classifying unit 4 receives the next message record from the message reading unit 3, extracts the task name and task ID from the message record, and specifies the task that has output the message. Then, in order to check whether or not the specified task is already registered as a classified task in the category management table 6, the task name and the task ID registered in the category management table 6 are searched. If there is no registration, the specified task is registered in the category management table 6. The category number corresponding to the registered task (task name and task ID) is a number obtained by adding 1 to the last registered category number. Then, along with the message received from the message reading unit 3, a new category management table 6 is displayed.
Is supplied to the result output section 5.

On the other hand, as a result of the search of the category management table 6, if the task name and the task ID have already been registered, they are not registered in the category management table 6 but are received from the message reading unit 3. The result message and the registered task name and the category number associated with the task ID are supplied to the result output unit 5.

The operation of the present invention has been briefly described above, and the description will be further continued with reference to specific examples.

For example, the task name and task ID of the first message record received by the message classifying unit 4 from the message reading unit 3 are “TASK”, respectively.
-A "and" 100 ", a management table is created in the category management table 6 as shown in FIG. 3B, and the message received from the message reading unit 3 (taken out of the message record). Message and the category number (here, “0”) are supplied to the result output unit 5.

If the message classifying unit 4 assumes that the task name and task ID of the next message record received from the message reading unit 3 are "TASK-B" and "200", respectively, 6 and the task name is "TA
It is checked whether a category with a task ID of “200” is registered in “SK-B.” At this time, the category management table 6 is as shown in FIG. Therefore, a new category is registered in the category management table 6. As a result, a management table is created in the category management table 6 as shown in FIG. The category number (here, “1”) whose task name and task ID correspond to “TASK-B” and “200”, respectively, and the message received from the message reading unit 3 are supplied to the result output unit 5. .

The task name and task ID of the next message record received by the message classifying unit 4 from the message reading unit 3 are respectively "TASK".
−B ”and“ 350 ”, the message classifying unit 4 searches the category management table 6 in the state of FIG. 3C. At this time, the management table of“ TASK-B ”is the second. However, the task ID of “TASK-B” in the management table is “20”.
0 ”, and the task ID“ 3 ”of the message received by the message
Different from 50 ".

In this case, even if the task names are the same, different tasks (tasks being executed for different purposes)
Therefore, a new table is registered in the category management table 6. As a result, a management table is created in the category management table 6 as shown in FIG.
The task name and task ID are each "TASK-B"
And the category number (here, “2”) corresponding to “350” and the message received from the message reading unit 3 are supplied to the result output unit 5.

Further, the message classifying unit 4 receives the next message record from the message reading unit 3, and the task name and task ID of the received message record are "TASK-A" and "100", respectively.
Assume that At this time, the message classification unit 4
The category management table 6 in the state of (d) is searched, and the first task name in the category management table 6 is “TAS”.
KA ”, a management table with a task ID of“ 100 ”is registered, and the task that has output the message is
It can be seen that the category number “0” has already been registered in the category management table 6.

In this case, the message classifying unit 4 does not perform registration in the category management table 6 and sets the task name and task ID to “TASK-A” and “10
A category number corresponding to “0” (here, “0”);
The message received from the message reading unit 3 is supplied to the result output unit 5.

Hereinafter, similarly, the message classifying unit 4
The message records received from the message reading unit 3 are sequentially analyzed, the received message records are classified into categories for each task, and the classified category numbers and messages are supplied to the result output unit 5.

The result output unit 5 is programmed to output a message to a different display area for each category number, and outputs a message from the message classification unit 4 (a message extracted from a message record). And the category number, the message is output to a predetermined window corresponding to the category number, for example, displayed on the screen of the console 7.

In the above-described embodiment of the present invention, a case has been described in which the message is displayed by classifying the messages by category. For example, it is possible to quickly determine whether or not an error has occurred in a task. In order to do so, it is possible to output only an error message.

This is because the message classification unit 4 analyzes the contents of the message record received from the message reading unit 3, and if it is an error message, a message (error message) extracted from the message record together with the category number as a result. This can be realized by programming so as to supply the data to the output unit 5 and otherwise supply nothing to the result output unit 5.

In addition to the above, O
From S1 to I / O device (message log file 2, etc.)
It is needless to say that the present invention can be practiced even if various other data (data) output to the

[0047]

As described above, according to the present invention, a plurality of programs operate at the same time in a multiprogramming processing system, and the message records output by the programs are stored in an external storage device or the like. A computer system that classifies the message records into predetermined categories using information contained in the stored message records, and retrieves and separately displays the message information contained in the message records for each category; By checking only a message group in a necessary category without checking the message output of (1), the target information (situation) can be quickly grasped.

Also, in order to classify messages, tasks are started by classifying the messages by execution management means or the like as described in JP-A-7-239827.
Since there is no need to provide an attribute according to the class by the identification attribute assigning means, the execution management means and the identification attribute assigning means are not required, and generally the task (via the OS)
Message classification can be realized by information included only in the message to be output.
