Oracle Data Integrator ETL からActive Directory データ連携

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

Active Directory 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 Active Directory 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Active Directory 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Active Directory 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Active Directory API に直接連携できます。

ここでは、JDBC を利用したActive Directory - Oracle のETL 連携を行います。Active Directory 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 Active Directory data.After reverse engineering, you can query real-time Active Directory data and create mappings based on Active Directory 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 ActiveDirectory.
    • Technology:Select Generic SQL.
    • Logical Schema:Enter ActiveDirectory.
    • Context:Select Global.
  3. On the Data Server screen of the resulting dialog, enter the following information:
    • Name:Enter ActiveDirectory.
    • Driver List:Select Oracle JDBC Driver.
    • Driver:Enter cdata.jdbc.activedirectory.ActiveDirectoryDriver
    • URL:Enter the JDBC URL containing the connection string.

      To establish a connection, set the following properties:

      • Valid User and Password credentials (e.g., Domain\BobF or cn=Bob F,ou=Employees,dc=Domain).
      • Server information, including the IP or host name of the Server, as well as the Port.
      • BaseDN: This will limit the scope of LDAP searches to the height of the distinguished name provided.

        Note: Specifying a narrow BaseDN may greatly increase performance; for example, cn=users,dc=domain will only return results contained within cn=users and its children.

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

      java -jar cdata.jdbc.activedirectory.jar

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

      Below is a typical connection string:

      jdbc:activedirectory:User=cn=Bob F,ou=Employees,dc=Domain;Password=bob123;Server=10.0.1.2;Port=389;
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter ActiveDirectory.
    • Schema (Work Schema):Enter ActiveDirectory.
  5. In the opened model click Reverse Engineer to retrieve the metadata for Active Directory tables.

Active Directory Data を編集して保存

After reverse engineering you can now work with Active Directory data in ODI. To edit and save Active Directory 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 Active Directory.You will load User 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 User table in Active Directory: CREATE TABLE ODI_DEMO.TRG_USER (LOGONCOUNT NUMBER(20,0),Id 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_USER 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_USER table from the Sales Administration model onto the mapping.
  7. Drag the User table from the Active Directory 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 USER_AP in TARGET_GROUP.
  10. In the USER_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

You can then run the mapping to load Active Directory data into Oracle.
