停止

SHUTDOWN

shutdown [ abort  normal | transactional | immediate ]
  • データベースとインスタンスを停止するには、最初にSYSOPERまたはSYSDBAとして接続する必要
  • 一部の停止モードでは、実際にデータベースを停止する前に、特定のイベント（トランザクションの完了またはユーザーによる切断など）の発生を待機します。これらのイベントに対するタイムアウト間隔は1時間
    • 停止をブロックしているイベントすべてが1時間以内に発生しない場合、停止コマンドは次のメッセージを表示して取り消されます。ORA-01013: ユーザーによって現行の操作の取消しがリクエストされました。
停止モード
  • デフォルトの停止モードはNORMAL
停止モード 内容 新規接続 セッション トランザクション 次回インスタンス・リカバリ
NORMAL 通常の停止 不可 切断待機 完了待機 不要
TRANSACTIONAL アクティブトランザクションを完了し、予定どおりにインスタンスを停止 不可 切断 完了待機 不要
IMMEDIATE 即時停止 不可 切断 暗黙的にロールバック 不要
ABORT 強制終了 不可 強制終了 強制終了 必要
