DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process monitoring technique in a fault management system for a running process (task) in a computer system, and more particularly, to an arbitrary process whose name is designated as a monitoring target when a monitoring process abnormally ends. The present invention relates to a process monitoring system and a process monitoring method capable of flexibly setting a process monitoring start / end period by distributing an interlocked process.

[0002]

2. Description of the Related Art Abnormal termination of a process that plays an important role in a computer system, such as a resident process resident and waiting to accept a connection request from another machine, leads to a serious problem such as a system down. Sometimes. Therefore, when an important process is abnormally terminated, it is necessary to promptly perform a process of notifying the operator of a failure, restarting the abnormally terminated process, and restarting the system. As a conventional technique for performing such control, for example, Japanese Unexamined Patent Publication No.
(Prior art) and JP-A-9-44376 (second prior art).

In the first prior art described in Japanese Patent Application Laid-Open No. 5-342008, a parent process (management process) for monitoring a process is provided, and when a process terminates abnormally, the parent process terminates abnormally. Send It is disclosed that when the parent process receives the abnormal end notification, it requests another child process to perform post-processing (rollback or the like). However, this method is effective only between processes having a parent-child relationship, and the parent process cannot detect the abnormality if an abnormality occurs such that the child process to be monitored cannot send an end notification.

In a second prior art described in Japanese Patent Application Laid-Open No. 9-44376, a parent process (management process) activates a child process and registers the process ID of the child process in a process ID management table. The child process locks the common semaphore, and unlocks the semaphore when the child process terminates abnormally. The parent process detects the abnormal termination of the child process and sends a signal to the child process based on the information in the process ID management table. It discloses a method of specifying a child process that has terminated abnormally by performing the above process and performing processing such as restarting the child process.

Although this method is versatile in that it can be executed by any operating system that can use a semaphore, this method also manages a child process in a relationship between a parent process and a child process. In addition, the child process to be monitored requires special creation. Therefore, the monitoring target is always limited to a process that can be created under a specific fault management system. Therefore, processes manufactured by other vendors started from other services are not monitored. Therefore, when designing and manufacturing a process monitoring system as a general-purpose product, these process monitoring methods cannot be used.

[0006]

However, the above prior art has the following problems. First, the first problem is that the current process monitoring method is a management method of child process management by a parent process,
It is not suitable for monitoring the survival of processes manufactured by other vendors. The reasons are that the parent-child relationship is used for the monitoring method, that the monitored child process needs to be built to be monitored, and that the user cannot arbitrarily specify the process to be monitored. It is in.

[0007] A second problem is that processing when an abnormal termination of a process is detected is fixed. In other words, even when a process terminates abnormally, there is a certain degree of abnormal termination, and there may be a fatal situation where restart is impossible. In this case, if the system is designed to be restarted upon abnormal termination, there is a possibility that the system may fall into an infinite loop of abnormal termination → restart → abnormal termination. The reason for this is that it has not been determined for what reason the operation has been abnormally terminated. This is because, in some cases, even when an abnormal end is detected, it is necessary to perform restart only after notifying the operator of the failure and removing the cause of the failure without restarting.

[0008] A third problem is that it is not possible to flexibly change the timing of executing the process monitoring. That is, when monitoring an arbitrary process, this process may be started before the monitoring process, or may be started later. If the monitoring process is activated first, the monitoring process immediately starts the process monitoring after the activation, so that the process is absent, and thus it is erroneously determined that an abnormal situation has occurred. The reason is that means for controlling the start / end timing of the process monitoring is not provided.

The present invention has been made in view of such a problem, and an object of the present invention is to monitor a process specified by an arbitrary user in a failure management method of a running process (task) in a computer system. It is to provide a possible process monitoring system and method. A second object of the present invention is to provide a process monitoring system and a process monitoring method capable of executing a process corresponding to a failure situation when detecting abnormal termination of a process. A third object of the present invention is to provide a process monitoring system and a process monitoring method capable of flexibly changing a process monitoring period in order to distinguish a process from stopping due to abnormal termination when it is known that the process stops normally. It is in.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The features of the embodiment described below are as follows.
Monitoring process means for monitoring a process, process monitoring start / end means for arbitrarily setting a process monitoring period, and a process management table of an operating system for solving a problem of arbitrarily monitoring a process designated by a user A process monitor that detects abnormal termination of the monitored process and monitors any process, and defines the process name of the monitored process and the linked process to be executed when the process terminates abnormally. A monitoring process definition file that solves the problem of monitoring the process specified by the user, and in order to take appropriate measures according to the abnormal termination of the process, check the status of the abnormal termination of the process and take appropriate appropriate linked processing. Interaction processing determination unit to determine and take appropriate measures according to abnormal termination of the process Process execution unit that executes a linked process in response to abnormal termination of a process, and sets the start time and end time of process monitoring, and appropriately sets the process monitoring period for any process. By providing a means, it is possible to monitor a process specified by any user, execute a process corresponding to a failure situation when detecting an abnormal termination of the process, and stop the process due to abnormal termination when it is known that the process stops normally. The point is that the process monitoring period can be changed flexibly. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram for explaining a process monitoring system according to an embodiment of the present invention. In FIG. 1, 1 is a monitoring process unit, 2 is a process monitoring start / end unit, 3 is a monitoring process definition file, 4 is an operating system, 5 is a process group to be monitored, 11 is a process monitoring unit, and 12 is an interlocking process determination unit. , 13 are interlocking process execution units, 21 is a process monitoring start unit, 22 is a process monitoring end unit, 23 is a schedule unit, 41 is a process management table, and 51,...

Referring to FIG. 1, in the embodiment of the present invention, a monitoring process means 1 for monitoring a process, a start time and an end time of the process monitoring are set, and a monitoring period of the process monitoring for an arbitrary process is set. Process monitoring start / end means 2 for appropriately setting (in other words, controlling the start / end timing of the process monitoring), the names of the monitoring target process group 5 (monitoring target processes 51,..., 5N) and abnormal termination In addition to defining the interlocking process when
A monitoring process definition file 3 for solving a problem of monitoring a process arbitrarily specified by a user, an operating system 4, and a monitoring target process group 5 to be monitored
(Monitoring target processes 51,..., 5N).

The monitoring process means 1 checks the status of the abnormal termination of the process in order to take appropriate measures according to the abnormal termination of the process, and examines the status of the abnormal termination of the process. An interlocking process determination unit 12 that determines an interlocking process (in other words, determines an interlocking process when a process ends abnormally), and an interlocking process with respect to a process abnormal end in order to take appropriate measures according to the abnormal end of the process (In other words, execute the linked process when the process ends abnormally)
It has.

The process monitoring unit 11 searches the process management table 41 of the operating system 4 and, when the process to be monitored terminates abnormally, the monitoring process unit 1
To that effect. In order to take appropriate measures according to the abnormal termination of the process, the interlocking process determination unit 12 obtains the termination code of the abnormal termination of the process when the process monitoring unit 11 detects the abnormal termination of the process. The monitoring process definition file 3 is searched using the end code as a key to determine a corresponding interlocking process. Linked processing execution unit 1
3 executes the interlocking process determined by the interlocking process determination unit 12 in order to take appropriate measures according to the abnormal termination of the process. The linked processing is, for example, restarting a process that has ended abnormally, notifying the operator of a failure, and the like.

The process monitoring start / end unit 2 includes a process monitoring start unit 21 for transmitting a process monitoring start to the monitoring process unit 1, a process monitoring end unit 22 for transmitting a process monitoring end, a process monitoring start unit 21 and a process monitoring unit. A schedule unit 23 for scheduling and executing the monitoring end unit 22 is provided. The process monitoring start unit 21 transmits a process monitoring start notification to the monitoring process means 1. The process monitoring termination unit 22 transmits a process monitoring termination notification to the monitoring process unit 1. The schedule unit 23 schedules the execution times of the process monitoring start unit 21 and the process monitoring end unit 22, and executes the process monitoring execution period (in other words, the process monitoring start unit 21 is executed before the process monitoring end unit 22 is executed). Period).

In this embodiment, an arbitrary process is to be monitored, and the start / stop timing of the monitoring process means 1 and the start of the monitored process group 5 (monitored processes 51,..., 5N) to be monitored. Since the order of the stop / stop times is not fixed, it is necessary to arbitrarily set the start / end times of the process monitoring. If the monitoring process unit 1 starts the process monitoring immediately after the startup without setting the process monitoring start / end unit 2, the monitoring target process group 5 (the monitoring target processes 51,...
5N) may not be started yet, and may be erroneously determined to be an abnormal situation. Similarly, the monitoring target process group 5 (the monitoring target process 51,
, 5N) are terminated before the monitoring process means 1, the monitoring target process group 5 (monitoring processes 51,
, 5N) may be erroneously determined to be abnormally terminated. Therefore, the process monitoring execution period needs to be set at a time when the monitoring target process group 5 (monitoring target processes 51,..., 5N) surely lives.

The monitoring process definition file 3 defines the name of the process to be monitored and the cooperative processing when the process ends, in association with the end code.

As the operating system 4, an operating system 4 (for example, Windows NT (trademark), which can obtain the survival information of the process having the specified name from the process information of the operating system 4)
Windows95 (TM), UNIX (TM), etc.)
Is the target. The operating system 4 has a process management table 41 for managing a process name of a currently running process and a process ID corresponding to the process name. Operating systems 4 such as Windows NT (trademark), Windows 95 (trademark), and UNIX (trademark) meet this condition. The monitoring target process group 5 (monitoring target processes 51,..., 5N) to be monitored is an arbitrary process.

Next, the overall operation of this embodiment will be described in detail with reference to FIGS. FIG. 2 is a flowchart for explaining a process monitoring method according to one embodiment of the present invention.

First, after being started (step A01), the monitoring process means 1 waits for a process monitoring start notification (step A21) from the process monitoring start unit 21. The process monitoring start unit 21 is scheduled so as to be started at a time when all of the monitored process groups 5 (monitored processes 51,..., 5N) should be started, and started by the schedule unit 23, and the monitoring process unit 1 (Step A21).

The monitoring process means 1 receives this notification (step A02) and starts process monitoring.
The monitoring process definition file 3 is read, and the process name of the monitoring target process is obtained (step A03). Information is acquired from the process management table 41 of the operating system 4 based on the process name, and settings are made so that a notification can be received when the monitored process group 5 (the monitored processes 51,..., 5N) ends abnormally. (Step A04). Although this setting differs depending on the operating system 4, the operating system 4 is capable of acquiring process information managed by the operating system 4 and confirming the existence of a process with the specified name.
If so, it can be set. If any of the monitoring target process groups 5 (monitoring target processes 51,..., 5N) does not exist (NO in step A05), the monitoring process definition file 3 is read, and the processes are restarted, and the failure notification to the operator is linked. The process is executed (Step A09).
Monitored process group 5 (monitored processes 51,..., 5
N) are all present (YE in step A05)
S), the monitored process group 5 (the monitored process 51,
, 5N) until an abnormal end is detected (step A06). When abnormal termination is detected (step A0)
7) Acquire an end code of the terminated process (step A08). Searches the monitoring process definition file 3 using the abnormally terminated process name and the termination code as keys,
The corresponding interlocking process (restart of the process, etc.) is executed (step A09).

The monitoring process means 1 waits for a predetermined period of time until the abnormally terminated monitored process group 5 (monitored processes 51,..., 5N) is restarted (step A1).
0). When restart is detected (YE in step A10)
S), the restarted process is added to the monitoring target again (step A11), and the process returns to the process end waiting process (step A06). If the restart cannot be detected after a predetermined time (NO in step A10), the monitoring of this process is abandoned, and the process returns to process waiting (step A06).

Hereinafter, this processing is continued until the process monitoring end notification is received (step A12). Then, the monitoring target process group 5 (the monitoring target process 51,
, 5N), the process monitoring end unit 22 is activated by the schedule unit 23 (Step A22), after waiting for the end of the process waiting (Step A6).

Upon receiving the process monitoring end notification (step A12), the process monitoring unit 11 stops monitoring the monitoring target process group 5 (monitoring processes 51,..., 5N) (step A13), and thereafter monitors the monitoring target process group. 5 (monitoring target processes 51,..., 5N) is not performed (step A13 to step A14). Therefore, the monitoring target process group 5 (the monitoring target process 51,
, 5N) is stopped, the interlocking process corresponding to the failure is not executed.

The schedule unit 23 periodically executes the process monitoring end unit 22 and subsequently executes the process monitoring start unit 21. This means restarting process monitoring. In other words, even if the process is not restarted in time in the restart waiting process (step A10) when the process ends abnormally, the process may be manually restarted by an operator or the like thereafter. In order to make such a process subject to process monitoring again, the process monitoring unit 11 is restarted from the beginning, and if there is a restarted process, it can be incorporated into the process monitoring target.

Next, a specific example of the operation of the present embodiment will be described. FIG. 3 shows the operation of the process monitoring system of FIG.
FIG. 4 is a schematic diagram of a monitoring process definition file 3 used in the operation (process monitoring method) of the process monitoring system of FIG. Here, a case in which the monitoring target processes 51, 52, and 53 are monitored will be described.

Referring to FIG. 3, after receiving the process monitoring start notification, the monitoring process means 1 reads the monitoring process definition file 3 and then executes the operating system 4.
Is set so that process information managed by the process can be acquired and abnormal termination of the monitored process can be detected. This setting differs depending on the operating system 4. In the following, Wi
The case of WindowsNT ™ will be described. First, RegQueryValueE of Win32 API
The performance information is acquired by calling the x function by designating HKEY_PERFORMANCE_KEY. Since this performance information includes the process names of all the running processes and the corresponding process IDs, the monitoring process means 1 can acquire the process IDs of the monitoring target processes 51,. . Win32 API for the acquired process ID
The process handle can be obtained by calling the OpenProcess function of. Set this process handle and wait function (WaitForMul)
By calling (typeObjects), a notification can be received from the operating system 4 when the monitoring target process ends. It can be set in this way.

In the case of Windows 95 (trademark), the process handle cannot be obtained by this method, but the process handle can be obtained by using the Toolhelp32 API instead. The rest is Wind
owsNT (Trademark).

On the other hand, in the case of UNIX (trademark), the process monitoring unit 11 is divided into another process (or another thread), and the process to be monitored exists in the process management information (/ proc) of the operating system 4. Check regularly by polling. When the absence is detected, the monitoring process means 1 is notified. Polling can also be set by a method of periodically issuing a ps command to confirm the existence of a monitored process.

In the process monitoring system according to the present embodiment, as shown in FIG. 3, the monitored process 52 starts last and stops first. Therefore, in order to normally monitor the existence of the monitoring target process 52, the process monitoring start unit 21 (step A21 in FIG. 3) schedules the monitoring target process 52 to be issued after the startup of the monitoring target process 52, and notifies the process monitoring end notification unit ( Step A in FIG.
22) is scheduled to be issued before the monitoring target process 52 stops. This scheduling enables normal monitoring of the monitoring target processes 51,..., 53. If the transmission of the process monitoring start notification (step A21 in FIG. 3) is issued before the start of the monitored process 52, the monitoring process means 1 detects the absence of the monitored process 52 and erroneously determines that an abnormality has occurred. I will judge. Further, if the process monitoring end notification transmission (step A22 in FIG. 3) is issued after the monitoring target process 52 is stopped, the monitoring process means 1 erroneously determines that the monitoring target process 53 has abnormally ended.

Now, consider the case where the monitored process 53 has abnormally terminated. Referring to FIG. 3, the operating system 4 is Windows NT (trademark), Windows
In the case of s95 (trademark), the monitoring process means 1 uses GetExitCod as the end code of the process 53 to be monitored.
Call and obtain the eProcess function. Monitoring process definition file 3 using CCC, which is the process name of the monitoring target process 53, and an end code as keys (see FIG. 4)
Search for.

In the example shown in FIG. 3, the process name is CCC,
Since the end code is 1 and the interlocking process is a restart,
The interlocking process execution unit 13 restarts the monitoring target process 53. If the monitoring target process 53 is started within a predetermined time, the monitoring process means 1 sets the monitoring target process 53 as a monitoring target again and continues the process monitoring. That is, even when the monitored process 53 ends abnormally again, the restart processing is performed.

On the other hand, in the case of UNIX (trademark), an end code cannot be obtained unless the monitoring process means 1 and the monitoring target processes 51,..., 53 have a parent-child relationship. Therefore, the monitoring target processes 51,..., 53 need to have a mechanism for outputting an end code to a file or the like, and the monitoring process means 1 reading this file to determine the end code. Others are Windows NT (trademark), Windows
Same as ws95 ™.

Next, an example will be described in which the abnormally terminated process does not restart within a certain period (see NO in step A10 shown in FIG. 2) and the operator manually starts this process after the timeout period. I do. FIG. 5 is a diagram showing a specific example of the operation of the process monitoring system of FIG. 1 (process monitoring method of FIG. 2), and FIG. 6 is a monitoring process definition file used in the operation of the process monitoring system of FIG. 5 (process monitoring method). FIG. 3 is an image diagram of FIG.

In the example shown in FIG.
Ends abnormally with an end code of -1. In this case, since the end code is -1, the monitoring process means 1 refers to the monitoring process definition file 3 shown in FIG. 6 and notifies the operator only of a failure and does not restart the monitoring target process 53. . For this reason, the monitoring process unit 1 executes a time-out determination (step A1 shown in FIG. 2).
0 and NO). After removing the cause of the failure, the operator manually restarts the monitored process 53.
The schedule unit 23 executes the process monitoring end unit 22 and the process monitoring start unit 21 at regular intervals.
And become the target of process monitoring again.

As described above, according to the present embodiment, the following effects can be obtained. First, the first effect is that the monitoring target process group 5 (monitoring process 51,..., 5N) does not need to have a parent-child relationship with the monitoring process means 1, and the monitoring target process group 5 (monitoring process 51,..., 5N) side, there is no need to create processing, so that any process can be set as a monitoring target. The reason is that the process management table 4 managed by the operating system 4 for process monitoring
This is for directly using No. 1.

The second effect is that the monitored process group 5
When the abnormal termination of the (monitoring target processes 51,..., 5N) is detected, it is possible to determine the abnormal termination state by checking the termination code instead of simply restarting, so that a flexible failure handling process is possible. In the case of a logic that always restarts after an abnormal termination, or when an unrecoverable failure occurs, the possibility of falling into an infinite loop of abnormal termination → restart → abnormal termination → ... That can be prevented. In the case of such a failure, the monitoring process means 1 may need to simply notify the operator of the occurrence of the failure and manually activate the abnormally terminated process after removing the cause of the failure.

A third effect is that the process monitoring start / end time is determined by the process monitoring start / end means 2, so that the user can arbitrarily set the process monitoring period, and thus can be started at any time. / The process to be stopped can be monitored. If the process monitoring start / end unit 2 is not provided, the process monitoring is started / terminated at the start / stop timing of the monitoring process unit 1 or other fixed timing, so that the monitored process is limited. For example,
When monitoring a process that is started several minutes after the start of the operating system 4, the monitoring process means 1 should start the process monitoring after this process has been started.
Can be set to be input after this process is completed.

It should be noted that the present invention is not limited to the above embodiments, and it is clear that the embodiments can be appropriately modified within the scope of the technical idea of the present invention. Further, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to suitable numbers, positions, shapes, and the like for implementing the present invention. In each drawing, the same components are denoted by the same reference numerals.

[0041]

Since the present invention is configured as described above, the following effects can be obtained. The first effect is that an arbitrary process having no parent-child relationship can be monitored. Further, as a result that no special process is required for the process to be monitored, the range of processes that can be monitored can be expanded. For example, processes manufactured by other vendors can also be monitored. The reason is that process information is obtained directly from the operating system in order to monitor the process. The second effect is that when an abnormal termination of a process is detected, the corresponding process can be sorted according to the status of the abnormal termination. As a result, the corresponding process to be performed depending on the status of the abnormal termination can be set in detail, and To be able to respond appropriately. The reason for this is to obtain the end code of the process and sort the interlocking process according to the end code. The third effect is that the process monitoring execution period can be arbitrarily changed. As a result, the process monitoring function can be stopped at a time when it is known that the process has been stopped, and useless failure notification is performed. , Restart processing and the like can be prevented. The reason is that the process monitoring start unit and the process monitoring end unit are provided independently.
