新しいジョブのDBA初日-バックアップとセキュリティを確認する-方法は?他に何をチェックする必要がありますか?

通常、新しい環境で開始するときは、バックアップがどこにあるか、最後にフルが取得されたとき、最後に復元が適用されたのはいつか、そしてセキュリティもチェックする傾向があります。

これを行う方法は、T-SQLを使用する方法です。

バックアップを確認する

SQL Serverデータベースのログ配布を監視するさまざまな方法

質問:

上記以外に、新しい環境を始める際に優先的に確認すべきことはありますか?

この正確な理由から、私は無料の(そしてオープンソースの) sp_Blitz を書きました。

人々は私にSQL Serverを渡して、「あなたはDBAであり、あなたはこのことを管理します」と続けていました。私は次のようなものをすばやく分析できるものが必要でした:

  • バックアップされていないか、破損がチェックされていないデータベース
  • サポートされていないSQL Serverのビルド
  • 危険なトレースフラグとデータベース設定
  • 不適切なsp_configureオプション

実行するだけで、パラメーターは必要ありません。優先順位が付けられたヘルスチェックが表示されます。優先度1-50はすぐにジャンプしたいものであり、優先度51+は後で書き留めておきたいものです。
