Resource adapters collection
To view the list of installed and configured resource adapters that we can use, install new resource adapters, create additional configurations of installed resource adapters, or delete resource adapter configurations. We can install a stand-alone resource adapter archive (RAR) file, or manage embedded adapters that are installed as part of the installation of an application.
Configure a single instance resource adapter after a resource adapter archive (RAR) file is installed. The RAR file can either be stand-alone or embedded in an application through the admin console or through the scripting tool. A checkbox is located on the console for you to specify that you want a single instance to be created at run time.
To view this admin console page, click Resources > Resource Adapters > Resource adapters .
A resource adapter is an implementation of the Java™ Platform, Enterprise Edition (Java EE) Connector Architecture (JCA) spec that provides access for applications to resources outside of the server or provides access for an enterprise information system (EIS) to applications on the server. Resource adapters can provide application access to resources such as DB2, CICS, SAP and PeopleSoft. A resource adapter can provide an EIS with the ability to communicate with message-driven beans that are configured on the server. Some resource adapters are provided by IBM; however, third party vendors can provide their own resource adapters. A resource adapter implementation is provided in a resource adapter archive file; this file has an extension of .rar. 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.
To view the resource adapters that are provided with the appserver, select Show built-in resources in Preferences.
- Scope
Level at which this resource adapter is visible. For general information, read about admin console scope settings.
Some considerations that you should keep in mind for this particular panel are:
- Change the scope enables you to see which resource adapter definitions exist at that level.
- Change the scope does not have any effect on installation. Installations are always done under a scope of node, no matter what you set the scope to.
- By creating a new resource adapter from this panel, change the scope to what you want it to be before clicking New.
- Install RAR
Specifies to install a resource archive (RAR). We can upload a RAR file from the local file system, or specify an existing RAR file on a server.
The RAR file must be installed at the node level.
- New
Specifies to create a copy of a resource archive that is already installed in the appserver. This will create a copy of the resource adapter that you select in the table.
If we wish to create a copy of an installed resource adapter, specify a server for the scope, and click New. We cannot create a copy of a resource adapter at the node scope. To install a new resource adapter, click Install RAR.
- Delete
Specifies to delete the copy of a resource adapter. This will delete the copy that you select in the table.
- Update RAR
Specifies to update the resource adapter that you select in the table. Update a resource adapter archive (RAR) file when you 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, so updating the adapter might be beneficial if we require a certain set of configuration options. We can choose if we would like to update the resource adapter for all of the nodes in a cell or all the nodes in a cluster. If some of the nodes are earlier than V7.0, the RAR update will not be supported until those nodes are migrated to V7.0.
- Name
Name of the resource adapter.
