Abstract
Description

図1は、第1の実施形態に係るプログラム処理装置100の機能ブロック図である。図1に示されるように、プログラム処理装置100は、構成管理部101と、アスペクト適用部102と、コンポーネント200と、コンポーネント300と、を備える。
図2、図3及び、図4を用いて第1の実施形態におけるプログラム処理装置100の動作を説明する。図2は、ルーティング部201とコネクタ部301とを各コンポーネントに適用する動作を表すフローチャートである。
・変更対象であるコンポーネント(本実施形態においてはコンポーネント200)の処理インストラクションを特定する変更情報

第3の実施形態には、コンポーネント200の接続先を複数用意し、またコンポーネント200と同じコンポーネントを接続先とすることにより、アプリケーションの高負荷時に処理を分散する効果がある。これにより、アプリケーション設計時には想定していなかったコンポーネント内の特定処理の性能問題を、短時間で回避する仕組みを提供できる。
本発明を実施するための第4の実施形態は、第3の実施形態において、分散配備されるコンポーネントを、ネットワーク的に分断されているサーバに配備する場合で、ルータ等のネットワーク機器への設定が必要な場合の実施形態である。例えば、VLANなどを利用しており、ルータハードウェアに対して設定変更を実施するような場合である。
図8は、第4の実施形態に係るプログラム処理装置110と各サーバ120、130、140との機能ブロック図である。
本実施形態の動作については、ルーティング部201とコネクタ部301(または401)との間で通信接続を確立する前に、当該通信接続を可能とする設定をネットワーク機器150に要求する点において、第3の実施形態の動作手順と異なる。
第4の実施形態によれば、複製したコンポーネントの配備に合わせてネットワーク機器の設定を実施することにより、例えば遠隔のシステムへ処理を分散させることが可能となる。これは、近年発展しつづけているクラウド環境を利用した、分散処理システムの自動構築を可能とする。
