Install a resource adapter archive

The application server uses the classes and other code that comprise a resource adapter archive (RAR) to support the resource adapters that you configure. A RAR file, which is often called a Java EE Connector Architecture (JCA) connector, must comply with the JCA Specification. We can meet these requirements by using a supported assembly tool to assemble a collection of JAR files, other runnable components, and utility classes into a deployable resource adapter archive (RAR). We can then install the RAR file in the application server. A resource adapter archive provides the classes and other code to support a resource adapter for access to a specific EIS, such as the Customer Information Control System (CICS). Therefore, you can only configure resource adapters for an EIS after you install the appropriate RAR file.

When you use the Install RAR dialog to install a RAR file, the scope you define on the Resource Adapters page has no effect on where the RAR file is installed. We can install RAR files only at the node level, which you specify on the Install RAR page.

To set the scope of an RAR file to a specific cluster, or server, after you install the RAR file at each node level, create a copy of the RAR file with the appropriate cluster or server scope.


Procedure

  1. Navigate to the Resource adapter panel. Click Resources > Resource Adapters > Resource adapters .

  2. Install a new resource adapter archive.

    1. Click Install RAR. A dialog opens for installing a RAR file and configuring the associated resource adapter. Only click New to configure a new resource adapter for a previously installed RAR file.
    2. Browse to find the appropriate RAR file.

      • If your RAR file is located on your local workstation, select Local path, and browse to find the file.

      • If your RAR file is located on your server, select Remote file system, and specify the fully qualified path to the file.

    3. Click Next.

  3. Configure the resource adapter name and any other properties needed under General Properties. For more details on the settings that you can configure, such as the J2C connection factories, see the topics Installing resource adapters within applications and Configuring resource adapters.

  4. Click OK.

  5. Optional: Create a copy of the RAR file with a different scope level. After you install the RAR file at each node level, you can create another copy of the file that has a specific server or cluster as the scope for that file.

    • If you do not create a copy of your RAR at the cluster scope, then create identical factories (connection factories, admin object, and activation specifications) at the node level for each of your nodes in the cluster. By creating the copy of your RAR, provided a placeholder for your factories and circumvent the need to create identical factories at the node level for each of your nodes in the cluster.
    • We must still install the RAR binaries (files, such as jars and xml deployment files) on each node for the RAR to operate successfully.

    1. Click Resources.

    2. Click Resource Adapters.

    3. Select the scope level and then click NEW.

    4. Choose the RAR file from the installed archive path.

    5. Click OK.


Results

You have installed a resource adapter archive that provide access to the EIS when it is properly configured. If configure more settings, or change some settings that were configured during the installation process, refer to the topic on configuring a resource adapter in the admin console for more information.
