図8は、本発明の実施の形態2による可用性モデル生成支援装置1の構成を示すブロック図である。図1と同一の符号は同等の構成を表している。実施の形態2では、実施の形態1のようにモデルモジュール格納部102から直接可用性モデル合成に使用するモデルモジュールをユーザに選択させるのではなく、可用性モデルの特徴を自然言語などで提示し、ユーザに選択させることで可用性モデルを合成する。以下、かかる相違点を中心に説明する。
(II)運用操作は、操作対象を再起動するか。(該当する操作例:障害を未然に防ぐための若化操作)
(A) 全てがNOの場合
(B) (I)のみがYESの場合
(C) (II)のみがYESの場合
(D) (I)、(II)ともにYESの場合
(α)状態監視
(β)重要な設定項目の変更(例えば、オペレーティングシステムの環境変数の変更など)
(γ)重要な設定項目の変更後に再起動(例えば、ネットワーク設定変更後の設定反映のための再起動など)
まず、可用性モデル生成支援装置1が、可用性モデルに関する特徴の選択肢をユーザに提示する(ステップS1000)。
図11は、本発明の実施の形態3による可用性モデル生成支援装置1の構成を示すブロック図である。図1と同一の符号は同等の構成を表している。実施の形態3では、モデルモジュールに不足がある場合にモデルモジュールの追加・修正が可能である。以下、かかる相違点を中心に説明する。
