Changing the Connection Associated with an Adapter Service at Runtime
Adapter services allow you to connect to the adapter's resource and initiate an operation on the resource from Integration Server. To use Adapter for OPC you create adapter services.
Integration Server then uses adapter connections that you defined earlier to execute the adapter services.
Adapter services are based on templates provided with Adapter for OPC. Each template represents a specific technique for working on a resource, such as using the Describe service to retrieve node references.
An adapter service template contains all the necessary code required to work with the resource. These templates can be customized with specific data sets to create a new service.
Some familiarity with using Software AG Designer is required. For more information, see the webMethods Service Development Help.
