OpenSwitch supports a redundant environment with two “mutually-aware” OpenSwitch servers that serve the same pools of two database servers. Each OpenSwitch server is aware of the other OpenSwitch server and whether the connections and Adaptive Server for which that server is responsible are running or not, which prevents a OpenSwitch from being a single point of failure.
Figure 1-6: Mutually-aware OpenSwitch servers
See Chapter 6, “Using Mutually-aware OpenSwitch Servers,” to configure this functionality.
