Oracle Data Integrator ETL からAWS Management データ連携

この記事では、Oracle Data Integratorを使用してAWS Management data をデータウェアハウスに転送する方法を説明します。

AWS Management への読み書きにJDBC 標準を使用して既存のスキルを活用します。 CData JDBC Driver for AWS Management は、Oracle Data Integrator(ODI)などのETL ツールへの統合によって、リアルタイムのAWS Management data をデータウェアハウス、ビジネスインテリジェンス、およびビッグデータテクノロジに連携します。

JDBC 接続を使用すると、ODI 内の他のデータベースと同じようにAWS Management を使用できます。RDBMS やフラットファイルを使用する代わりに、ドライバーを使用してリアルタイムでAWS Management API に直接連携できます。

ここでは、JDBC を利用したAWS Management - Oracle のETL 連携を行います。AWS Management エンティティのデータモデルをリバースエンジニアリングした後、マッピングを作成してだdata loading strategy を選択します。ドライバーはSQL-92 をサポートしているため、この最後の手順は組み込みSQL からSQL Loading を選択することで簡単に行えます。

ドライバーをインストール

To install the driver, copy the driver JAR and .lic file, located in the installation folder, into the ODI userlib directory:

On Unix: ~/.odi/oracledi/userlib On Windows: %APPDATA%\Roaming\odi\oracledi\userlib

Restart ODI to complete the installation.

モデルのリバースエンジニアリング

Reverse engineering the model retrieves metadata about the driver's relational view of AWS Management data.After reverse engineering, you can query real-time AWS Management data and create mappings based on AWS Management tables.

  1. In ODI, connect to your repository and click New -> Model and Topology Objects.
  2. On the Model screen of the resulting dialog, enter the following information:
    • Name:Enter AWSDataManagement.
    • Technology:Select Generic SQL.
    • Logical Schema:Enter AWSDataManagement.
    • Context:Select Global.
  3. On the Data Server screen of the resulting dialog, enter the following information:
    • Name:Enter AWSDataManagement.
    • Driver List:Select Oracle JDBC Driver.
    • Driver:Enter cdata.jdbc.awsdatamanagement.AWSDataManagementDriver
    • URL:Enter the JDBC URL containing the connection string.

      To authorize AWSDataManagement requests, provide the credentials for an administrator account or for an IAM user with custom permissions:

      1. Set AccessKey to the access key Id.
      2. Set SecretKey to the secret access key.
      3. Set Region to the region where your AWSDataManagement data is hosted.

      Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

      For assistance in constructing the JDBC URL, use the connection string designer built into the AWS Management JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.awsdatamanagement.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      Below is a typical connection string:

      jdbc:awsdatamanagement:AccessKey=myAccessKey;Account=myAccountName;Region=us-east-1;
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter AWSDataManagement.
    • Schema (Work Schema):Enter AWSDataManagement.
  5. In the opened model click Reverse Engineer to retrieve the metadata for AWS Management tables.

AWS Management Data を編集して保存

After reverse engineering you can now work with AWS Management data in ODI. To edit and save AWS Management data, expand the Models accordion in the Designer navigator, right-click a table, and click Data.Click Refresh to pick up any changes to the data.Click Save Changes when you are finished making changes.

ETL プロジェクトを作成

Follow the steps below to create an ETL from AWS Management.You will load NorthwingProducts entities into the sample data warehouse included in the ODI Getting Started VM.

  1. Open SQL Developer and connect to your Oracle database.Right-click the node for your database in the Connections pane and click new SQL Worksheet.

    Alternatively you can use SQLPlus.From a command prompt enter the following:

    sqlplus / as sysdba
  2. Enter the following query to create a new target table in the sample data warehouse, which is in the ODI_DEMO schema.The following query defines a few columns that match the NorthwingProducts table in AWS Management: CREATE TABLE ODI_DEMO.TRG_NORTHWINGPRODUCTS (NAME NUMBER(20,0),PartitionKey VARCHAR2(255));
  3. In ODI expand the Models accordion in the Designer navigator and double-click the Sales Administration node in the ODI_DEMO folder.The model is opened in the Model Editor.
  4. Click Reverse Engineer.The TRG_NORTHWINGPRODUCTS table is added to the model.
  5. Right-click the Mappings node in your project and click New Mapping.Enter a name for the mapping and clear the Create Empty Dataset option.The Mapping Editor is displayed.
  6. Drag the TRG_NORTHWINGPRODUCTS table from the Sales Administration model onto the mapping.
  7. Drag the NorthwingProducts table from the AWS Management model onto the mapping.
  8. Click the source connector point and drag to the target connector point.The Attribute Matching dialog is displayed.For this example, use the default options.The target expressions are then displayed in the properties for the target columns.
  9. Open the Physical tab of the Mapping Editor and click NORTHWINGPRODUCTS_AP in TARGET_GROUP.
  10. In the NORTHWINGPRODUCTS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

You can then run the mapping to load AWS Management data into Oracle.
