Perform these steps in the Websphere Application Server administrative console:
Expand Resources.
Click Resource Adapters.
Click Install RAR.
The Install RAR button opens a dialog that enables you to install a J2EE Connector Architecture (JCA) connector and create a resource adapter for it. You can also use the New button, but the New button creates only a new resource adapter (the JCA connector must already be installed on the system).
Note: When installing a RAR file using this dialog, the scope you define on the Resource Adapters page has no effect on where the RAR file is installed. You can install RAR files only at the node level, and the node in which 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 install at the server, node, or cell level.
Browse to find the appropriate RAR file.
Click Next.
Enter the resource adapter name and any other properties needed under General Properties.
Click OK.
