Configuring server addresses with multi-home servers
If your setup uses multi-home servers to deploy different networks for the connections between the application and the servers than the servers themselves, you need to define the server addresses for the Transparent Connectivity (TC) connection with the HotStandby.TCConnect parameter, see HotStandby section.
From the application connection perspective, the address that is specified by using the HotStandby.TCConnect parameter takes precedence over the address that is specified by using the HotStandby.Connect parameter. The TC connection therefore uses the server addresses that are specified by using the HotStandby.TCConnect parameter, while the HotStandby connection between the servers uses the server addresses that are defined by using the HotStandby.Connect parameter.
