Description

以下に添付図面を参照して、本願のサーバ起動停止制御装置及びサーバ起動停止制御方法の実施例を詳細に説明する。なお、本願のサーバ起動停止制御装置及びサーバ起動停止制御方法は、以下の実施例により限定されるものではない。 Exemplary embodiments of a server start / stop control device and a server start / stop control method of the present application will be described below in detail with reference to the accompanying drawings. The server start / stop control device and the server start / stop control method of the present application are not limited to the following embodiments.

そして、サーバ起動／停止決定部１４４ａは、通信ネットワーク装置Ｂを構成するすべてのサーバが正常に稼動していることから通信ネットワーク装置Ｂが正常に稼動中であると判定する（ステップＳ３６２）。 Then, the server start / stop determination unit 144a determines that the communication network device B is operating normally because all the servers constituting the communication network device B are operating normally (step S362).

そして、ログ管理部１４６が、実行結果をログファイルに格納し（ステップＳ３９０）、サーバ起動停止制御装置１００ａは、通信ネットワーク装置Ｂの停止が実行されたこと、及び、通信ネットワーク装置Ａの停止が未実行であることを示す応答を、グラフィックユーザインタフェース１１０を介して保守者に通知して（ステップＳ３９１）、処理を終了する。 Then, the log management unit 146 stores the execution result in the log file (step S390), and the server start / stop control device 100a executes the stop of the communication network device B and the stop of the communication network device A. A response indicating that it has not been executed is notified to the maintenance person via the graphic user interface 110 (step S391) , and the process is terminated.

例えば、サーバ起動停止条件ファイル１３５ａは、図１８に示すように、サーバごとに、当該サーバを起動させるための制約を記憶する。一例を挙げると、実施例３に係るサーバ起動停止条件ファイル１３５ａは、「フロントサーバ１」に対応付けて、「ＤＢサーバ１又はＤＢサーバ２の起動が失敗した後の起動不可」を記憶する。ここで、上記した情報は、ＤＢサーバ１又は、ＤＢサーバ２の起動が失敗した場合には、フロントサーバ１を起動できないことを意味する。なお、図１８に示す情報は、あくまでも一例である。 For example, the server start / stop condition file 135a stores, for each server, restrictions for starting the server, as shown in FIG. For example, the server start / stop condition file 135a according to the third embodiment stores “unstartable after failing to start the DB server 1 or DB server 2” in association with “front server 1”. Here, the above-mentioned information means that the front server 1 cannot be started when the DB server 1 or the DB server 2 fails to start. Note that the information shown in FIG. 18 is merely an example.

ここで、フロントサーバ２は、故障が発生したために正常にプロセス及びＯＳを起動できなかった旨のエラー応答をサーバ起動停止制御装置１００ｂに返す（ステップＳ４２７）。サーバ起動／停止決定部１４４ｂは、フロントサーバ２からプロセス／ＯＳ起動応答（エラー応答）を受付けると、起動が失敗したため保守者の復旧作業が必要であると判定する（ステップＳ４２８）。そして、サーバ起動／停止決定部１４４ｂは、制約条件を参照して、次に停止させるサーバをフロントサーバ１と決定する（ステップＳ４２９）。なお、フロントサーバ２の起動が失敗したことが、ログ管理部１４６によってログファイル１３６に記録される。 Here, the front server 2 returns an error response indicating that the process and the OS could not be started normally due to a failure to the server start / stop control device 100b (step S427). It determines that the server start / stop determination unit 144b, when the front server 2 receives the process / OS start response (error response), it is necessary restoration work maintenance person for launch fails (step S428). Then, the server start / stop determination unit 144b refers to the constraint conditions and determines the next server to be stopped as the front server 1 (step S429). Note that the failure of starting the front server 2 is recorded in the log file 136 by the log management unit 146.

Claims
