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
