Connect to Redshift from a Connection Pool in WebLogic





Amazon Redshift JDBC Driver

Amazon Redshift データ連携のパワフルなJava アプリケーションを素早く作成して配布。

Use the CData JDBC Driver for Redshift to connect to Redshift data from Web applications running on WebLogic.

The CData JDBC Driver for Redshift enables you to follow standard procedures to integrate Redshift data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Redshift in WebLogic server.

Install the JDBC Driver in WebLogic Server

Add the driver JAR and license file to the classpath your application will be using. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, add the JAR to the WEBLOGIC_CLASSPATH environment variable. add the following line to the commEnv.cmd/sh script in WL_HOME\common\bin\.

set WEBLOGIC_CLASSPATH=your-installation-directory\lib\cdata.jdbc.redshift.jar;%WEBLOGIC_CLASSPATH%

If you want to add the driver to a specific domain, you will need to add the JAR to the PRE_CLASSPATH environment variable. Add the following line to the setDomainEnv.cmd/sh script in the bin subfolder of the folder for that domain:

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.redshift.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for Redshift

After installing the driver, create the connection.

  1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
  2. On the JDBC Data Source Properties page, enter the following information:
    • Name: Enter a user-friendly name; for example, redshiftjdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/Redshift.
    • Database Type: Select Other.

  3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

    • Driver Class Name: Enter the driver class, cdata.jdbc.redshift.RedshiftDriver, in this property.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:


      Redshift への接続には次を設定します:

      • Server: 接続するデータベースをホストしているクラスタのホスト名およびIP アドレス。
      • Port: クラスタのポート。
      • Database: データベース名、ブランクの場合ユーザーのデフォルトデータベースになります。
      • User: ユーザー名。
      • Password: ユーザーのパスワード。

      Server およびPort の値はAWS の管理コンソールで取得可能です:

      1. Amazon Redshift console ( を開く。
      2. Clusters ページで、クラスタ名をクリック。
      3. クラスタのConfiguration タブで、表示された接続文字列からクラスタのURL をコピーします。
      4. Database User Name: Enter the username, if not specified in the JDBC URL.
      5. Password: Enter the password, if not specified in the JDBC URL.

After selecting the server where you want to deploy the JDBC data source, you can now connect to Redshift data.

More WebLogic Integration

The steps above show how configure the driver in a simple connection pooling scenario. For more use cases and information, see the JDBC sections in the WebLogic Data Sources chapter of the Oracle Fusion Middleware documentation.
