Integration Server enables you to dynamically select the connection a service uses to interact with the adapter's resource. This feature enables one service to interact with multiple, similar backend resources.

For example, a service can be defined to use a default connection that interacts with your company's North American Oracle Applications database. However, at run time you can override the default connection and instead use another connection to interact with the company's European Oracle Applications database.

For more information about overriding a service's default connection at run time, see Dynamically Changing a Service's Connection at Run Time.
