同じビュー、非常に異なる実行時間（Oracleリンクされたサーバーは遅いですが2回目に限りあります）

MS SQLデータベースからOracleにデータをロードするETLジョブがあります。ジョブとパラメータはテーブルで定義されており、それらを1つずつ実行するラッパー・プロシージャがあります。同じビュー、非常に異なる実行時間（Oracleリンクされたサーバーは遅いですが2回目に限りあります）

私の問題は、ラッパーが最初のジョブを実行すると速く、約45-50秒でOracleにデータを挿入するということです。それが源からの異なる為替レートを取ることの最初のものとだけ異なる2番目のものに達するとき、それは20-22分かかります。

正確に同じ数の行（約24000）、同じ量のデータ、同じソーステーブルと宛先テーブル、唯一の違いはソースクエリのwhere句です。

私は非常に広範なロギングを実装しており、ソースデータベースからのデータの読み込み、変換、およびピボットは安定したパフォーマンスを持ち、常にほぼ同じ時間を費やしていることを示しています。それは最後のステップで、最初は高速でオラクルにプッシュし、残りの時間は遅くなります。

プロバイダを使用：OraOLEDB.Oracle

INSERT文では使用：

insert into LINKEDORACLESERVER..SCHEMANAME.TABLENAME select * from spec.staging_tablename

任意のアイデアをどのようにチェックするために？

UPDATE：

はコメントでユーザーammoQからアイデアを得ました。事は、私が2つの仕事を逆転させると、最初の仕事は痛いほど遅い仕事になり、2番目の仕事は速くなるということです。おそらく全体の問題は間違っているでしょう。

しかし、2つのジョブのパラメータが異なる場合、具体的にはSAP BPCのOLAPキューブから取得する必要がある為替レートのカテゴリはどうなりますか？彼らは同じソースから読み込み、同じ宛先テーブルに約24k行を書き込みますが、「レートA」の代わりに「レートB」を使用しています。

更新日2：少し近づいています。したがって、両方のジョブは、データをXcelsiusダッシュボードのデータマートとなるテーブルにプッシュしています。それは私がMS SQLでビューを構築したかなり特殊な構造を持っています。したがって、同じビューから同じテーブルにデータをロードします。

View in job 1: returns 23,512 rows. Execution time: 00:01:03. 
View in job 2: returns 23,512 rows. Execution time: 00:18:54.

これは、ビューの選択である：

転送の順序を変更できますか？最初に2番目のINSERTを実行するとどうなりますか？ –

うわー、とてもシンプルですが、まだ試していません。〜30分でお知らせします。 –

は、最初の挿入前に空の宛先テーブルですか？ – dlatikay

はあなたからあなたのデータを選択するビューをチェックし、この問題はオラクル側にはありません。（コメントを参照してください;-)

ここで学んだレッスン：devプラットフォーム上の他のものがかなり速く走っているからといって、他のプラットフォームが悪い/遅い/不十分であると仮定するのはあまり怠惰ではありません。 –

使用OPENQUERY句：

insert into openquery(LINKEDORACLESERVER,'select col1, col2, col3 from SCHEMANAME.TABLENAME') 
    select col1, col2, col3 from spec.staging_tablename;

その逆です。 MS SQLからOracleへのロード。 –

これは、SQL Server（table spec.staging_tablename）からOracle（テーブルSCHEMANAME.TABLENAME）までのスクリプトの動作を示しています。すべての列のリストを覚えておいてください – Miyazawa

まず、OPENQUERY句を正しく使用する方法を確認するためにSELECT句だけを試してください。 select * from openquery（LINKEDORACLESERVER、 'select col1、col2、col3 from SCHEMANAME.TABLENAME'） – Miyazawa

同じビュー、非常に異なる実行時間（Oracleリンクされたサーバーは遅いですが2回目に限りあります）
