Administer resource adapters

A resource adapter (RAR) represents an archive file. This file contains code that implements a library and connects to an Enterprise Information System (EIS) backend database. Typically, a single resource adapter can only connect to one type of enterprise information system (EIS) but it can support many different configurations for connections to that EIS. The resource adapter has many configuration properties that are defined in the J2C specification and set by the vendor who supplies the code.

For help with resource adapter settings, see these topics:

For information on configuring, modifying, and removing resource adapters, see these sections:

Install Java 2 Connector RAR files

You can use the administrative console to install a J2EE Connector Architecture (JCA) connector and create a resource adapter for it.

To install a Java 2 Connector RAR file, follow these steps:

  1. Start the administrative console.
  2. In the topology tree, expand Resources and click Resource Adapters.
  3. On the Resource Adapters page, click Install RAR.

    Note: When you install a RAR file with the administative console, the scope that you specify on the Resource Adapters page does not affect where the RAR file is installed. You can install RAR files only at the node level, and the node the file is installed on is determined by the scope on the Install RAR page. The scope you set on the Resource Adapters page determines the scope of the new resource adapters, which you can create at the server, node, or cell level.

  4. Specify the RAR file that you want to install, or click Browse... to select the file.
  5. Click Next.
  6. Specify the resource adapter name. You can also specify additional properties on this page.
  7. Click OK.

Create resource adapters

If a JCA connector is already installed on your system, and you want to create a new resource adapter for the connector, follow these steps:

  1. Start the administrative console.
  2. In the topology tree, expand Resources and click Resource Adapters.
  3. On the Resource Adapters page, click New.
  4. Specify a name and archive path. You can also specify additional properties on this page.
  5. Click Apply.
  6. After you create the resource adapter, you can configure J2C connection factories for it.
  7. Save the configuration.

Modify resource adapters

To modify a resource adapter, follow these steps:

  1. Start the administrative console.
  2. In the topology tree, expand Resources and click Resource Adapters.
  3. On the Resource Adapters page, select the name of the resource adapter that you want to modify.
  4. Make your changes.
  5. Click OK.
  6. Save the configuration.

Remove resource adapters

To remove a resource adapter, follow these steps:

  1. Start the administrative console.
  2. In the topology tree, expand Resources and click Resource Adapters.
  3. On the Resource Adapters page, select the checkbox for the name of the resource adapter that you want to remove.
  4. Click Delete.
  5. Save the configuration.
