- applied successfully : implying that the ServiceInstances have been refreshed to dynamically uptake the config change.
- persisted successfully : implying that the change has been persisted to the persistent store
- OR a restart of the server is required for the current changes to be made active. This option also means that any transient changes would need to be persisted before restarting the server.
- When a Configuration Bean is used to generate a ServiceInstanceDescriptor and if some mandatory properties are not set in the resultant ServiceInstanceDescriptor then the set of missing properties is communicated via the missingMandatoryProperties method.
