VisuNet RM Shell 6
Profiles Management App
Example 2 – Connecting Continuously to More Than One Host (via
"Backup Connection" Feature)
In this example, the RM / BTC connects automatically to a predefined host A. If the connection
fails, the RM / BTC will try to connect to the profile's backup connection (in this case, "host B")
after a predefined waiting time. If host B is also not reachable, the RM / BTC will try to connect
to the host B profile's backup connection (in this case, "host C"). You can easily create "loops"
of backup connections for your profiles. In this example, the backup connection of host C is
host A again.
Use case: If you have an infrastructure with redundant servers, you can set up the RMs / BTCs
to connect to a backup server if the main server fails.
