routing amongst virtual servers within same app

[acw]

Is it possible for virtual servers to be able to access each other within an app without having terminals defined?

Specifically, what I am looking for is to establish server 1 to be NIS master for other servers (NIS clients), and another server to be a separate monitoring server.

Thanks.

Appliances can communicate with other appliances in the same application only through terminals. This ensures that the architecture and inter-appliance interactions are visible on the diagram; on a more practical level, it ensures that you don't need to ever configure IP addresses for interactions between appliances (so that you can replicate the application using 'app copy' and not have to do manual reconfiguration of the intra-application interactions).

One approach I would recommend for the use case you described is to set up your server class with an 'nis_in' terminal and 'nis_out' terminal. If the nis_out terminal is unconnected, the appliance can assume it is running either independently or as a master. Master server receives and serves requests on its nis_in terminal. Appliances that have their nis_out terminal connected automatically assume slave mode and request info through it. See the attached diagram fragment.



Let me know if this will work for you.

Thanks. Will give that a shot.
