6.3.6 RegisterApplication ToC Previous Next

RegisterApplication is used to register a new Application Instance with a GlobalDiscoveryServer.

This Method shall only be invoked by authorized users.

Servers that support transparent redundancy shall register as a single application and pass the DiscoveryUrls for all available instances and/or network paths.

RegisterApplication will create duplicate records if the ApplicationUri already exists since misconfiguration of applications can result in different applications having the same ApplicationUri. Before calling this Method the Client shall call FindApplications to check if a record for the application it is using already exists. If records are found which appear to belong to different applications (e.g. the DiscoveryUrls are different) then the Client shall report a warning before continuing.

If registration was successful and auditing is supported, the GDS shall generate the ApplicationRegistrationChangedAuditEventType (see 6.3.12).
