Description

  The present invention relates to periodic processing and event processing for maintenance management executed between communication network constituent devices, and a maintenance management device and maintenance management for appropriately performing execution control when a plurality of processes that cannot be executed simultaneously compete with each other The present invention relates to a method and a maintenance management program.

  Conventionally, in order to provide and maintain an appropriate communication service, a communication network component device is used for maintenance management in addition to normal communication processing, such as periodic settings such as quality measurement and data settings and status input by maintenance personnel operations. Performs event processing such as command processing for monitoring.

  It is necessary to manage these periodic processes / event processes and execute the processes at the necessary timing and to end them reliably by performing competition control when the processes compete.

  Commonly considered competition control is (1) Prioritize first process (first process), do not execute the process that occurred during execution of the first process (second process), (2) Perform first process, prior process execution The process that occurred during the process (later process) waits until the advance process is completed, and starts executing after the process ends. (3) The subsequent process is prioritized, the earlier process is interrupted, and the subsequent process is executed. Basic method.

  However, the methods (1) and (2) have a problem that the subsequent processing is not carried out indefinitely when the first processing is delayed or when it is not terminated due to some trouble. (3) indicates that if the timing or procedure of interruption of the processing that was performed in the first step is wrong, or if the system status changes due to the subsequent processing, the first processing may not be resumed normally, or the first processing is frequently performed. If the process is interrupted, the advance processing may not be completed.

  As a technique for processing a plurality of transaction processes in parallel, there are techniques described in Patent Document 1 and Patent Document 2.

  Japanese Patent Laid-Open No. 2004-133830 describes a transaction process being executed or suspended when an instruction for a transaction process having a higher priority than the transaction process being executed or suspended is received during execution of another transaction process. A transaction concurrency control method is described in which a situation of contention of database resources with a requested transaction process is determined, and a transaction process to be canceled or suspended is appropriately determined.

  Further, in Patent Document 2, by setting the client priority in the client information database and giving priority to the transaction end request command of the client with high priority, the client with high priority is affected by the client with low priority. A transaction control method is described that allows a database to be accessed without receiving a message.

"0" is input.

  The operation of the process execution control unit 12 when the maintenance management apparatus 1 operates in a state where the management table is stored in the management table storage unit 11 will be described with reference to the flowchart of FIG.

  First, based on the information on the processing type 102 and the processing time 103 in the management table, it is monitored whether or not there is a process that has reached the start time of any of the processes subject to competition control (S1).

  When it is determined that the process start time of any process has arrived (“YES” in S1), the competition target process of the process that has reached the process start time is extracted based on the competition target process 108. It is determined whether the current execution state 107 of the process name 101 corresponding to the extracted conflict target process is currently being executed (execution state ON) or not being executed (execution state OFF) (S2).

  When the target device related to the competition target process is not currently being executed (execution state OFF) (“YES” in S2), the device indicated by the target device name 104 is accessed and executed for the process whose processing start time has arrived. At the same time, the current execution state 107 of the process in the management table is updated from OFF to ON (S3).

  Here, when the execution of the process is started, it is determined whether or not the timer setting time 105 of the management table is input for the process, and if it is input, the timer is set at the set time.

  Then, if the execution of the process is terminated while the timer has not timed out due to the setting of the timer (“NO” in S4) (“YES” in S5), the current execution state 107 of the process in the management table is turned ON. Is updated to OFF (S6). Further, when a time-out occurs due to a delay or failure of the process ("YES" in S4) before the end of the process execution, a forced stop or the like is performed based on the operation content 106 at the time-out of the management table (S7). . When the process is forcibly stopped, the current execution state 107 of the process in the management table is updated to OFF.

  When the target device related to the competition target process of the process whose process start time has arrived at step S2 is currently being executed (execution state ON) (“NO” in S2), based on the priority information 109 of the management table. Then, it is determined whether or not the subsequent priority 109b of the subsequent process at which the process start time has come is higher than the initial priority 109a of the previously executed competitive process (S8).

  As a result of the determination, when the subsequent priority 109b of the subsequent process when the process start time has arrived is higher than the initial priority 109a of the previous competitive process that has already been executed ("YES" in S8), The starting process is stopped and the current execution state 107 related to the starting process in the management table is updated from ON to OFF, and the non-priority count value 111a of the escalation information 111 related to the starting process cannot be completed because the starting process cannot be completed. 1 is added. Further, the device indicated by the target device name 104 is accessed for the subsequent processing when the processing start time arrives, and the execution is started, and the current execution state 107 regarding the subsequent processing of the management table is updated from OFF to ON (S9). ).

  Here, when the subsequent priority 109b of the subsequent process is equal to the prior priority 109a of the previous competitive process, which one is to be prioritized is specified in advance by the operator. "Priority" is set.

  When the execution of the subsequent process is started, if the timer setting time 105 of the management table is input for the process, the timer is set at this setting time, and while the time is not timed out by the setting of this timer (S4 When the execution of the process ends in “NO” (“YES” in S5), the current execution state 107 of the process in the management table is updated from ON to OFF (S6).

  In addition, the stopped starting process is stopped, an alarm is output, restarted after the end of the priority process, an NG response, or the like based on the non-priority operation content 110 of the management table for the process. Here, based on the operation content 110 at the time of non-priority, even when the subsequent process is resumed after the priority process ends, the extraction of the competition target process 108, the determination of the current execution state 107, the priority process based on the priority information The contention process based on the determination is performed.

  In step S8, when the subsequent priority 109b of the subsequent process whose processing start time has arrived is lower than the prior priority 109a of the previously executed competitive process ("NO" in S8), the initial process And the subsequent process is not executed, and 1 is added to the non-priority count value 111a of the escalation information 111 (S10). Further, the subsequent process that has not been executed includes stop, alarm output, restart after the end of the priority process, NG response, etc., based on the non-priority operation content 110 of the management table for the process.

  On the other hand, the operation of the escalation function unit 13 when the maintenance management apparatus 1 operates will be described with reference to the flowchart of FIG.

  In each process, the escalation function unit 13 monitors whether or not the non-priority count value 111a of the escalation information 111 in the management table exceeds the priority control threshold 111b (S11), and determines that the priority control threshold 111b has been exceeded. When this is done (“YES” in S11), the values of the advance priority 109a and the subsequent priority 109b of the priority information 109 of the process are updated by adding the priority addition value 111c (S12).

  When the values of the first priority 109a and the second priority 109b are added, the priority of the process is increased, and it is determined that the process has been executed based on the current execution state 107 of the management table (S13). "YES"), the non-priority count value 111a of the escalation information 111 is cleared to "0" (S14).

  A specific example when competition control is performed for a plurality of processes in the maintenance management apparatus 1 operating as described above will be described with reference to FIGS.

  First, when the processing start time (0:00) of the process “H” arrives, the competition processes “I” and “J” of this process “H” are not executed, so the maintenance management apparatus 1 changes to the maintenance target apparatus Y. An instruction to start execution of process “H” is transmitted (S21). In response, a primary response is transmitted from maintenance target apparatus Y to maintenance management apparatus 1 (S22), and process “H” is executed (S23). .

  Next, when the processing start time (1:00) of the process “I” arrives, the starting process “H” being executed is a competing process of the subsequent process “I”, and the subsequent priority “ Since “4” is higher than the starting priority “3” of the starting process “H”, a stop instruction for the starting process “H” is transmitted from the maintenance management apparatus 1 to the maintenance target apparatus Y (S24). A secondary response is transmitted from the maintenance target device Y to the maintenance management device 1 (S25), and the process “H” is stopped (S26).

  Then, an instruction to start execution of the process “I” is transmitted from the maintenance management apparatus 1 to the maintenance target apparatus X (S27), and in response thereto, a primary response is transmitted from the maintenance target apparatus X to the maintenance management apparatus 1 (S28). The matching process “I” is executed between the maintenance target device X and the maintenance target device Y (S29). For example, when the data (i) related to the data C is missing in the database y1 of the maintenance target device Y, “data CC” which is the data (i) related to the data C stored in the database x of the maintenance management device X is The matching process “I” is executed by being transmitted to the maintenance target apparatus Y and stored in the database y1.

  Next, when the processing start time (2:00) of the process “H” arrives, the starting process “I” being executed is a competing process of the subsequent process “H”, and the subsequent priority “ Since “3” is lower than the starting priority “4” of the starting process “I”, the starting process “I” is continued, and the execution start instruction for the subsequent process “H” is not transmitted (S30).

  At time (2:40), when the process “I” that has been executed is completed, a secondary response is transmitted from the maintenance target device X to the maintenance management device 1 (S31), and the management table of the maintenance management device 1 is updated. The

  Next, when the processing start time (4:00) of the process “H” arrives, the contention processes “I” and “J” of this process “H” are not executed, so the maintenance management apparatus 1 changes to the maintenance target apparatus Y. An instruction to start execution of process “H” is transmitted (S32). In response, a primary response is transmitted from maintenance target apparatus Y to maintenance management apparatus 1 (S33), and process “H” is executed (S34). .

  At time (5:20), when the process “H” that has been executed is completed, a secondary response is transmitted from the maintenance target device Y to the maintenance management device 1 (S35), and the management table of the maintenance management device 1 is updated. The

  Next, when the processing start time (6:00) of the process “J” arrives, the contention process “H” of the process “J” is not executed, so the process “J” is performed from the maintenance management apparatus 1 to the maintenance target apparatus Y. Is sent (S36), and the process "J" is executed between the maintenance target device X and the maintenance target device Y (S37).

  According to the above-described embodiment, with respect to the process for maintenance management of the communication network configuration device, parameters such as the contention process, execution status information, process priority information, and non-priority operation details are set in detail. By centrally managing, even when a plurality of processes that cannot be executed at the same time compete, the processes can be executed appropriately and flexibly.

  In addition, by setting the timer setting time and the operation contents at the time-out as necessary for each process, detection of abnormal delay in processing time and measures at that time are set, and the processing time of the process being executed is set It is possible to avoid a situation in which the non-priority processing on standby cannot be executed because the processing does not end abnormally or due to some trouble.

  In addition, the number of times of stopping or stopping as non-priority is counted for each process, and when a preset threshold value is exceeded, the priority is updated so as to increase, thereby continuing the non-priority state and performing processing. It is possible to prevent being overlooked for a long time.

  In addition, by setting finely the operation contents when it is determined that each process is non-prioritized, it is possible to perform competition control so that inappropriate process interruption does not occur.

  Further, in the above embodiment, it is determined whether or not the operation is to be updated based on the total interruption / cancellation time information indicating the interruption / cancellation time of the process that has been determined to be non-priority and is interrupted or canceled. Management table of update operation contents (stop, alarm output, NG response, etc.) when it is determined to update the operation based on the operation update threshold value indicating the threshold value to perform, the total interruption / stop time information, and the operation update threshold value It is stored in the storage unit 11, and the process execution control unit 12 monitors whether the interrupt / stop time of the process that is determined to be non-priority and interrupted or stopped exceeds the operation update threshold, and exceeds the operation update threshold. The operation may be executed based on the update operation content of the process when it is determined that the process has been performed.

  Moreover, it is also possible to construct a maintenance management program for causing the computer to function as a maintenance management apparatus by programming the functions of the maintenance management apparatus according to the present embodiment into a computer.

The number of times determined to be non-priority is counted for each process, and when this count value exceeds a preset threshold value, an added value set in advance for the advance priority and the subsequent priority for the process The maintenance management device according to claim 1, further comprising an escalation function unit that adds The management table storage unit, for each process related to maintenance of the terminal, interrupt / stop update indicating the operation content when the interrupt / stop time of the interrupted or interrupted process determined to be non-priority exceeds a preset threshold value Memorize the details of the operation,
The process execution control unit measures the interrupt / stop time of a process that has been determined to be non-priority and has been interrupted or stopped, and when it is determined that the measured value exceeds a preset threshold value, The maintenance management apparatus according to any one of claims 1 to 3, wherein the maintenance management apparatus operates based on the content of the suspension update operation. The management table storage unit further stores non-priority operation content indicating operation content when it is determined that non-priority with respect to the process to be competed,
5. The maintenance according to claim 1, wherein the process execution control unit operates based on a non-priority operation content of the management table storage unit with respect to a process determined to be non-prioritized. Management device. The maintenance management device connected to the maintenance target terminal
For each process related to the maintenance of the terminal, execution status information indicating whether it is currently executing or not executing, competing target process information indicating a competing target process that cannot be executed simultaneously, and its own process is executed as a starting process Management that stores a priority level indicating a priority level for a subsequent competitive process when it is in progress, and a subsequent priority level indicating a priority level for a previous competitive process when the process itself is a subsequent process A table storage step;
Competing target process information related to the execution target process is extracted based on the competing target process information stored in the management table storing step, and whether the competing target process is currently being executed or not being executed is determined in the management table. Judgment is made based on the execution state information stored in the storing step, and when it is determined that the process is currently being executed, the subsequent priority of the process to be executed and the prior priority of the process to be currently executed are determined. Obtained from the information stored in the management table storage step, when the subsequent priority of the execution target process is higher than the prior priority of the conflict target process currently being executed, The execution priority is stopped and the execution target process is prioritized, and the subsequent priority of the execution target process is the first priority of the conflict target process currently being executed. Remote maintenance method characterized by having a process execution control step to stop executing the processing of the execution target continues with priority execution processing of the competing interest as non-priority when low. To the maintenance management device connected to the maintenance target terminal,
For each process related to the maintenance of the terminal, execution status information indicating whether it is currently executing or not executing, competing target process information indicating a competing target process that cannot be executed simultaneously, and its own process is executed as a starting process Management that stores a priority level indicating a priority level for a subsequent competitive process when it is in progress, and a subsequent priority level indicating a priority level for a previous competitive process when the process itself is a subsequent process Table storage function;
Competing target processing information related to the processing to be executed is extracted based on the competing target processing information stored by the management table storage function, and whether the competing target processing is currently being executed or not executed is determined in the management table. Judgment is made based on the execution state information stored by the storage function, and when it is determined that the process is currently being executed, the subsequent priority of the execution target process and the prior priority of the competing target process currently being executed are determined. Obtained from the information stored by the management table storage function, if the subsequent priority of the execution target process is higher than the prior priority of the conflict target process currently being executed, the execution of the conflict target process is not performed The execution priority is stopped and the execution target process is prioritized, and the subsequent priority of the execution target process is the first priority of the conflict target process currently being executed. Remote maintenance management program for executing the process execution control function to abort the execution of the processing of the execution target continues with priority execution processing of the competing interest as non-priority when low.
