Redundancy Setup

After setting up redundancy how the is following situation handled:

  1. A Client is launched from a workstation the first time from the Master node web page. This creates a shortcut on the desktop.
  2. After a period of time, the user stops the client.
  3. The Master node fails.
  4. What happens when someone tries to launch the client using the shortcut created on the desktop in step 1?

Ignition 7.8.3
Redundancy set up using defaults.


Generally, it won’t work. A java cache of the application might make it work, but you cannot rely on it.
The native client launchers solve this problem: you can specify gateway.backup.addr=… in addition to gateway.addr=… in those shortcuts. That allows the launcher to locate the backup server if the master is dead.
