To use an instance of CentraSite with webMethods Mediator, you must define a gateway that identifies the specific webMethods Mediator that you want to use. A gateway is a registry object that represents a particular instance of a policy enforcement point (in this case, an instance of webMethods Mediator). The target object specifies the address of the Mediator's deployment endpoint, which is the endpoint that CentraSite uses to interact with Mediator to deploy virtual service.

If you use multiple Mediators with an instance of CentraSite, you must create a gateway for each Mediator. To make the Mediators easier to distinguish when they are viewed in CentraSite, consider adopting a naming convention for gateways that clearly identifies to which environment the target belongs (for example, development, test, production).

To communicate with CentraSite, a Mediator must have a user account on CentraSite. You have to establish this user account before you can configure Mediator's connection to CentraSite. Because Mediator reads and writes to certain objects in the registry (such as virtual services), its user account requires a specific set of permissions. These permissions are identified in the Mediator user documentation.
