DBプロジェクトとAzureサーバーを比較するときにSSDTスキーマ比較が失敗する


12

エンタープライズDBを構築したSQLデータベースプロジェクトがあります。SSDTのスキーマ比較ツールを使用して、内部およびAWSがホストするSQLサーバーに数回デプロイしました。

SQL Ent 2012 sp2を実行しているAzure Hosted Win 2012 Serverに投稿するときの問題。「比較が完了しました。違いは検出されませんでした」と戻ってきます。

Enterprise Managerを開き、スキーマをSQLプロジェクトと比較して、違いがあることがわかるので、これが間違っていることはわかっています。

2014年のリリースでこのツールがどのように機能しなくなったかについて話している記事をいくつか見つけましたが、それらはバージョンの違いにあります。

[はい、Googleでこれを行いました。私がそうするのを忘れることで悪名高いので、述べます。] https://www.google.com/webhp?ie=utf-8&oe=utf-8#q=ssdt+data+compare+fail+to+detect+difference&start=10

私がチェックした他のことには、DBアカウントに無制限のアクセス権があることを確認することが含まれます。管理コンソールに接続できます。ローカルプログラムに接続できます。

問題があったことの最後の確認:

  1. 番号1の単一の戻り値を持つSPを作成しました。
    1. テストのために何も返されない可能性があります。
  2. SPを作成した後、すべてのインスタンスでスキーマ比較を実行しましたが、Azureサーバーを除くすべてのインスタンスで差異が示されました。

更新

これはサーバーで明示的に行われていることを確認しました。2台のコンピューター上の2人のユーザーがまったく同じ問題を抱えているからです。

TL; DR

Visual Studioが実行しているクエリがブロックされ、クエリがタイムアウトします。


私の状況でこれをうまく処理できたことがわかりました:ブロックのためにタイムアウトしました!

Microsoft SQL Serverデータツールのアプリケーション名、スキーマ比較のフィルターを使用してプロファイラートレースを実行し、Visual Studioスキーマ比較イベントをキャプチャしました。

VSが比較が完了したと主張すると、特定のクエリに到達してから停止します。

問題のクエリのバッチは次のとおりです。

SSMSでクエリを実行すると、問題のあるサーバーで実行が終了することはありませんが、他のすべての環境では1秒未満で済みます。

だから私はそれをバラバラにし始め、次の3つのシステムビューから読み取っているクエリが問題であることがわかりました。

  • sys.server_event_session_actions
  • sys.server_event_session_events
  • sys.server_event_session_fields

これらのシステムビューの最初のレコードには28のレコードしか含まれてCount(*)いません(aを実行することで検出されます)が、(NOLOCK)ヒントを使用しない限りデータは返されません... [b] locking problem!

ブロッキングチェーンの先頭を見つけるのは簡単ですが、拡張イベントセッションであるため殺すことはできませんでした。この問題の修正はここにあります:https : //support.microsoft.com/en-gb/kb/2511963

しかし、うまくいけば、チェーンのヘッドをうまく削除して、正常に戻すことができます!


編集:影響を受けるSQL Serverのメンテナンスウィンドウが有効になったので、再起動するとSPIDがクリアされ、比較が再び機能するようになりました!

また、今後の読者に役立つ可能性のあるブロッキングチェーンのヘッドを見つけるために作成した簡単なスクリプトを次に示します。 http://gvee.co.uk/files/sql/admin.blocking_chains.sql
