You can deploy the resources that are required to support new methods in an Enterprise Information System (EIS), without affecting any resources that are already deployed, by using primary and secondary adapters. You must configure the WebSphere® Adapters nodes in your message flows to use the secondary adapters.
The primary adapter for a WebSphere Adapters node contains its connection information and part of its interface; the secondary adapters contain the rest of the interface. The primary library contains message model metadata for the parts of the interfaces that are supported by the node; the secondary libraries define the rest of the model.
Complete the following steps to configure a message flow so that it can be extended by secondary adapters and libraries.
Add the library to a BAR file, then deploy the BAR file to the integration server. For more information, see Deploying a message flow that uses WebSphere Adapters.
