A resource adapter can be provided as a stand-alone adapter or as part of an application, in which case the resource adapter is referred to as an embedded adapter. Refer to related task, Installing resource adapters within applications, for more information on embedded resource adapters. A resource adapter is an implementation of the Java EE Connector Architecture (JCA) specification. Enterprise applications can use a resource adapter to access resources outside of the application server including relational databases like DB2, OLTP systems like CICS, and EIS like SAP and PeopleSoft. A resource adapter can provide an EIS with the ability to communicate with message-driven beans (MDB) configured on the server. Resource adapters are provided by IBM or third party vendors. A resource adapter implementation is provided in a resource adapter archive file; this file has an extension of .rar.

To display a list of all of the resource adapters that are defined for a specific scope, select that scope.

To view the stand-alone resource adapters provided with the application server, select the Show built-in resources checkbox in the Preferences section.

To view additional information about, or to change the settings of a specific resource adapter, click the resource adapter name.

To perform an action on a specific resource adapter, select the checkbox beside the resource adapter name and click the appropriate button detailed below.


Install RAR

Install a resource adapter archive. Installs the files associated with a RAR to the node specified in the scope menu. Additionally, a resource adapter instance is created from the RAR at node scope.

We can upload a RAR file from the local file system, or specify a RAR file on a remote file system. The RAR file must be installed at the node level.


New

Create an new resource adapter instance from an installed RAR.

To create additional resource adapter instances at scopes other than node, select the desired scope for the new resource adapter, and click New. In the subsequent screen, enter a name for the new resource adapter and select the installed RAR from which to create the adapter. Complete any of the optional fields as needed. We cannot create a new resource adapter instance at the node scope.


Delete

Delete the selected resource adapter.


Update RAR

Update the selected resource adapter. Update a resource adapter archive (RAR) file when we determine that a resource adapter, or a set of resource adapters, needs to be updated with a different version or implementation.

Different versions or implementations of resource adapters can include different settings, therefore, updating your adapter might be beneficial if you require a specific set of configuration options. We can update the resource adapter for all of the nodes in a cell or all the nodes in a cluster. If some of your nodes are earlier than v7.0, the RAR update is not supported until those nodes are migrated to v7.0 or later.


Name

Name of the resource adapter.

Specifies a text description of the resource adapter.

This description is a free-form text string to describe the resource adapter and its purpose.


Scope

Level at which this resource adapter is visible. For general information, read about dmgr console scope settings.
