A setHiveParam message is sent by a client application or another cell service to add a hive parameter to the PM cell. The project needs to exist prior to calling this service. If the hive and parameter name already exist the record will be updated.
The domain, username, and password are sent in the header of the message so it does not need to be sent separately in the <message_body>.
