Description

ジョブ管理サーバが管理しているジョブ実行サーバの高負荷状態の緩和、高負荷状態が原因の予想実行時間超過によるジョブのエラー等が発生するのを防止するジョブ管理システム、その方法及びそのプログラムに関する。   The present invention relates to a job management system, a method thereof, and a program therefor, which alleviate a high load state of a job execution server managed by the job management server and prevent occurrence of a job error due to an excess of an expected execution time caused by the high load state .

一般的なジョブ管理システムでは、サーバの負荷が一時的に増大するなどの現象が発生していてもジョブの実行に影響がないことが求められている。この技術的要件を満たすためには、サーバが高負荷状態になった場合に、高負荷状態をどのようにして緩和するか、高負荷状態によるジョブ実行遅延の影響をどのようにして抑止するかといった課題が存在する。   A general job management system is required to have no influence on job execution even if a phenomenon such as a temporary increase in server load occurs. To meet this technical requirement, how to mitigate the high load state when the server is in a high load state, and how to suppress the impact of job execution delay due to the high load state There is such a problem.

そこで、特許文献1には、CPU負荷量毎にジョブ実行を動的に変化させるジョブスケジュール方式が開示されている。   Therefore, Patent Document 1 discloses a job schedule method that dynamically changes job execution for each CPU load.

特許文献2には、業務内の各ジョブに、統計情報のCPU使用時間に応じて割り当てるCPU使用率を自動で算出するCPU使用率最適化方式が開示されている。   Patent Document 2 discloses a CPU usage rate optimization method that automatically calculates a CPU usage rate to be assigned to each job in a job according to the CPU usage time of statistical information.

特許文献3には、サーバのCPU使用率が閾値下限を越えている場合には、サーバが過負荷状態と判断するCPU余裕管理とトランザクション優先度による負荷分散方法が開示されている。   Patent Document 3 discloses a load distribution method based on CPU margin management and transaction priority, in which the server determines that the server is overloaded when the CPU usage rate of the server exceeds the threshold lower limit.

しかしながら、特許文献1乃至3に開示されている発明は、単にCPU使用率が高いだけでは、ハードウェア資源を有効に活用しているからCPU使用率が高いのか、過剰にジョブが投入された結果、CPU使用率が高いのかが判断できないという問題点がある。   However, the inventions disclosed in Patent Documents 1 to 3 use hardware resources effectively only by a high CPU usage rate, so that the CPU usage rate is high or the result of excessive jobs being submitted. There is a problem that it cannot be determined whether the CPU usage rate is high.

又、CPU使用率が低くても、ハードディスクへの読み込み又は書き込みが頻繁に発生する等の他の要素でジョブが遅延する可能性もあり、そのような場合には、CPU使用率だけではハードウェア資源の負荷の度合いが正確に把握できないという問題点もある。   Even if the CPU usage rate is low, the job may be delayed due to other factors such as frequent reading or writing to the hard disk. There is also a problem that the degree of resource load cannot be accurately grasped.

本発明は上記に鑑みてなされたもので、ハードウェア資源の有効活用が可能なジョブ管理システム、その方法及びそのプログラムを提供することを目的とする。   The present invention has been made in view of the above, and an object thereof is to provide a job management system capable of effectively utilizing hardware resources, a method thereof, and a program thereof.

[第1の実施の形態の動作]
本発明の第1の実施の形態に係るジョブ管理システムの動作の流れを図面を用いて詳細に説明する。
[Operation of First Embodiment]
An operation flow of the job management system according to the first embodiment of the present invention will be described in detail with reference to the drawings.

最初に、図2を用いて負荷度の算出からジョブ実行サーバのジョブ多重度を設定する処理の説明を行う。図2は、本発明の第1の実施の形態に係るジョブ管理システムの負荷度の算出からジョブ実行サーバのジョブ多重度を設定する処理の流れを示すブロック図である。   First, a process for setting the job multiplicity of the job execution server from the calculation of the load degree will be described with reference to FIG. FIG. 2 is a block diagram showing a flow of processing for setting the job multiplicity of the job execution server from calculation of the load degree of the job management system according to the first embodiment of the present invention.

負荷状態判定部112が、ジョブ管理サーバ110が管理している各ジョブ実行サーバ120のCPU使用率と、各ジョブ実行サーバで実行されたジョブの実行時間の統計と最新の実行時間の差分から負荷情報を分析し、各ジョブ実行サーバの負荷度というパラメータを定期的に算出する処理を行う。ここで、負荷状態判定部112は、各ジョブ実行サーバの負荷度が予め決められた閾値を超えていた場合、当該サーバが高負荷状態であると判断する。   The load state determination unit 112 determines the load based on the CPU usage rate of each job execution server 120 managed by the job management server 110, the statistics of the execution time of the job executed on each job execution server, and the difference between the latest execution time. The information is analyzed, and a process of periodically calculating a parameter called load level of each job execution server is performed. Here, when the load level of each job execution server exceeds a predetermined threshold, the load state determination unit 112 determines that the server is in a high load state.

なお、各ジョブ実行サーバ120のCPU使用率は、各ジョブ実行サーバ120にインストールされているOS(Operating System)が測定したものをジョブ管理サーバ110がネットワークを通じて取得するものとする。   The CPU usage rate of each job execution server 120 is acquired by the job management server 110 via the network as measured by an OS (Operating System) installed in each job execution server 120.

各ジョブ実行サーバ120は、このCPU使用率をジョブ管理サーバ110に送信する専用の手段を別途備え、又ジョブ管理サーバ110は、CPU使用率を受信する専用の手段を別途備えてもよいが、各ジョブ実行サーバ120とジョブ管理サーバ110とがサーバとして備えている既存の通信手段を援用してもよい。   Each job execution server 120 includes a dedicated unit for transmitting the CPU usage rate to the job management server 110. The job management server 110 may include a dedicated unit for receiving the CPU usage rate. You may use the existing communication means with which each job execution server 120 and the job management server 110 are provided as a server.

次に、パラメータ決定部113は、高負荷と判断されたジョブ実行サーバ120に関してジョブ管理パラメータ保存領域111に保存された負荷度とジョブ多重補正度と実行時間補正度との第1の表を参照して、高負荷なジョブ実行サーバのジョブ多重補正度、実行時間補正度のパラメータを決定する。   Next, the parameter determination unit 113 refers to the first table of the load degree, job multiple correction degree, and execution time correction degree stored in the job management parameter storage area 111 for the job execution server 120 determined to be highly loaded. Then, the parameters of the job multiple correction degree and the execution time correction degree of the high-load job execution server are determined.

負荷度とジョブ多重補正度と実行時間補正度とを対応させた第1の表はサイジング等によって予め決定し、ジョブ管理パラメータ保存領域111に登録する。その例を表1に示す。   The first table in which the load degree, the job multiple correction degree, and the execution time correction degree are associated with each other is determined in advance by sizing or the like and registered in the job management parameter storage area 111. An example is shown in Table 1.

次に、ジョブ多重度補正度送信手段115は、高負荷状態と判断されたジョブ実行サーバに、ジョブ多重補正度のパラメータを送信する。
Figure 2010198184
Next, the job multiplicity correction degree transmission unit 115 transmits the job multiplicity correction degree parameter to the job execution server determined to be in the high load state.

ジョブ多重補正度受信手段121は、ジョブ多重補正度のパラメータを受信する。   The job multiple correction degree receiving unit 121 receives a parameter of the job multiple correction degree.

新ジョブ多重度設定部122は、ジョブ実行サーバの現在のジョブ多重度とジョブ多重補正度の積を新しいジョブ実行サーバのジョブ多重度としてジョブ多重度保存領域123に保存する。   The new job multiplicity setting unit 122 stores the product of the current job multiplicity of the job execution server and the job multiplicity correction degree in the job multiplicity storage area 123 as the job multiplicity of the new job execution server.

第二に、図3を用いて高負荷状態と判断されたジョブ実行サーバへのジョブ投入を行う際のパラメータの設定処理の説明を行う。図3は、本発明の第1の実施の形態に係るジョブ管理システムの高負荷状態と判断されたジョブ実行サーバ120へのジョブ投入を行う際のパラメータの設定処理の流れを示すブロック図である。   Second, a parameter setting process when a job is submitted to a job execution server determined to be in a high load state will be described with reference to FIG. FIG. 3 is a block diagram showing the flow of parameter setting processing when a job is submitted to the job execution server 120 determined to be in a high load state of the job management system according to the first embodiment of the present invention. .

ジョブパラメータ制御部114は、高負荷状態と判断されたジョブ実行サーバ120に投入されるジョブに関して、現在のジョブの予想実行時間と実行時間補正度の積を新しいジョブの予想実行時間として設定する。   The job parameter control unit 114 sets the product of the expected execution time of the current job and the execution time correction degree as the expected execution time of the new job for the job to be input to the job execution server 120 determined to be in a high load state.

次に、予想実行時間とジョブの優先度をどの程度補正するかのパラメータ(ジョブ優先度補正値)との第2の表を参照し、新たに設定した予想実行時間に対応するジョブ優先度補正値を取得し、得られたジョブ優先度補正値と投入されるジョブの優先度の積を新しいジョブの優先度として設定する。この負荷度を基にした予想実行時間とジョブ優先度補正値とを対応させた第2の表は予め設定しておき、ジョブ管理パラメータ保存領域111に登録する。その例を表2に示す。   Next, referring to the second table of parameters (job priority correction values) of how much the estimated execution time and job priority are corrected, job priority correction corresponding to the newly set expected execution time A value is acquired, and the product of the obtained job priority correction value and the priority of the input job is set as the priority of the new job. The second table in which the estimated execution time based on the load level is associated with the job priority correction value is set in advance and registered in the job management parameter storage area 111. An example is shown in Table 2.

Figure 2010198184
ジョブ管理サーバ110は、ジョブパラメータ制御部114が決定したジョブ優先度に基づいて、ジョブ実行サーバ120にジョブを投入する。又、ジョブ実行サーバ120は、ジョブ多重度保存領域123に保存した新しいジョブ多重度に従ってジョブを処理する。これにより、ジョブ実行サーバの高負荷状態の緩和、高負荷状態が原因の予想実行時間超過によるジョブのエラー等が発生するのを防止するジョブ管理システムを実現できる。
Figure 2010198184
The job management server 110 submits a job to the job execution server 120 based on the job priority determined by the job parameter control unit 114. Further, the job execution server 120 processes the job according to the new job multiplicity stored in the job multiplicity storage area 123. As a result, it is possible to realize a job management system that alleviates the high load state of the job execution server and prevents the occurrence of a job error or the like due to the expected execution time exceeding due to the high load state.

[第2の実施の形態]
本発明の第2の実施の形態として、図2において、負荷状態判定部112で負荷度を算出した際、高負荷状態と判断されたジョブ実行サーバ120の負荷度が前回計算した負荷度と比べて異なる場合と、負荷度が平常状態と判断される負荷度の閾値を下回っていた場合とで、それぞれどのような動作になるかを示す。
[Second Embodiment]
As a second embodiment of the present invention, when the load level is calculated by the load state determination unit 112 in FIG. 2, the load level of the job execution server 120 determined to be in a high load state is compared with the load level previously calculated. The operation is different when the load level is lower than the threshold value of the load level at which the load level is determined to be normal.

高負荷状態と判断されたジョブ実行サーバの負荷度が前回計算した負荷度と異なる場合は、パラメータ決定部113は、再びジョブ管理パラメータ保存領域111に保存されている負荷度とジョブ多重補正度と実行時間補正度との第1の表を参照し、新たなジョブ多重補正度及び実行時間補正度を決定する。   If the load level of the job execution server determined to be in a high load state is different from the load level calculated previously, the parameter determination unit 113 again determines the load level and job multiple correction level stored in the job management parameter storage area 111. With reference to the first table of execution time correction degrees, new job multiple correction degrees and execution time correction degrees are determined.

その後、ジョブ多重補正度送信手段115、ジョブ多重補正度受信手段121を通じてジョブ実行サーバに通知された新しいジョブ多重補正度と、高負荷状態と判断される前にもともと設定されていたジョブ多重度との積を新たなジョブ多重度としてジョブ多重度保存領域123に保存する。   Thereafter, the new job multiple correction degree notified to the job execution server through the job multiple correction degree transmitting unit 115 and the job multiple correction degree receiving unit 121, and the job multiplicity originally set before the high load state is determined. Is stored in the job multiplicity storage area 123 as a new job multiplicity.

同様に、ジョブパラメータ制御部114でも、新しい実行時間補正度と、高負荷状態と判断される前にもともと設定されていたジョブの予想実行時間との積を新たな予想実行時間として設定する。又、ジョブの優先度についても、新たな負荷度ごとの予想実行時間とジョブ優先度補正値との第2の表を参照し、新たなジョブ優先度補正値を決定する。その後、新たなジョブ優先度補正値と高負荷状態と判断される前にもともと設定されていたジョブの優先度との積を新たなジョブの優先度として設定する。   Similarly, the job parameter control unit 114 also sets the product of the new execution time correction degree and the expected execution time of the job that was originally set before the high load state is determined as a new expected execution time. As for the job priority, a new job priority correction value is determined with reference to the second table of the estimated execution time and the job priority correction value for each new load level. Thereafter, the product of the new job priority correction value and the job priority that was originally set before the high load state is determined is set as the new job priority.

高負荷状態と判断されたジョブ実行サーバ120の負荷度が、平常状態と判断される閾値を下回っていた場合は、高負荷状態と判断されていたジョブ実行サーバ120のジョブ多重度、当該サーバに投入されるジョブの予想実行時間及びジョブの優先度を高負荷状態と判断される前にもともと設定されていた値に変更する。平常状態と判断される閾値と、高負荷状態と判断される閾値は異なり、平常状態と判断される閾値の方を高負荷状態と判断される閾値より低く設定する。   If the load level of the job execution server 120 determined to be in the high load state is below the threshold value determined to be in the normal state, the job multiplicity of the job execution server 120 determined to be in the high load state is set to the server. The estimated execution time of the job to be submitted and the priority of the job are changed to values originally set before it is determined that the load is high. The threshold value determined as the normal state is different from the threshold value determined as the high load state, and the threshold value determined as the normal state is set lower than the threshold value determined as the high load state.

なお、本発明は、装置のみならず方法及びプログラムの発明としても実施できる。   The present invention can be implemented not only as an apparatus but also as a method and program invention.

本発明は、縮退運用方式でのジョブ管理に適しており、かかる方式でのハードウェア資源の有効活用が可能なジョブ管理システムに利用することができる。   The present invention is suitable for job management in the reduced operation method, and can be used for a job management system capable of effectively using hardware resources in such a method.

The job parameter control process sets the product of the new execution time correction degree and the expected execution time of the job that was originally set before the high load state is determined as a new expected execution time, and the second A new job priority correction value is determined with reference to the table, and the product of the new job priority correction value and the job priority that was originally set before the high load state is determined Set as job priority,
The product of the new job multiple correction degree notified through the job multiple correction degree transmission process and the job multiple correction degree reception process and the job multiplicity originally set before being determined as a high load state is a new job. 17. The job management program according to claim 13, further causing the job execution server to execute a process of saving as multiplicity.
高負荷状態と判断された前記ジョブ実行サーバの前記負荷度が、平常状態と判断される閾値を下回っていた場合は、高負荷状態と判断されていた前記ジョブ実行サーバのジョブ多重度、該ジョブ実行サーバに投入されるジョブの予想実行時間及びジョブの優先度を高負荷状態と判断される前にもともと設定されていた値に変更し、平常状態と判断される閾値を高負荷状態と判断される閾値より低く設定することを特徴とする請求項13乃至17のいずれか1項に記載のジョブ管理のプログラム。   If the load level of the job execution server determined to be in a high load state is below a threshold value determined to be in a normal state, the job multiplicity of the job execution server determined to be in a high load state, the job The estimated execution time and job priority of the job submitted to the execution server are changed to the values that were originally set before it was determined to be a high load state, and the threshold value that is determined to be a normal state is determined to be a high load state. 18. The job management program according to claim 13, wherein the job management program is set lower than a threshold value.
