VIPA as the destination address, or specifying a host name that maps to the static VIPA in the remote syslogd configuration. When the recipient syslogd instance is running in a sysplex environment, additional availability features are available that should be explored. For example, you can use a multiple application-instance dynamic VIPA (DVIPA) to represent the syslogd instance on a given system, and the remote syslogd instances are configured to use that DVIPA address as the destination IP address for the messages they forward. In this configuration, if a failure to the MVS system or TCP/IP stack on which the syslogd instance is running occurs, the DVIPA is automatically moved to a predefined backup system that is currently active. This enables the syslogd instance on that backup system to begin processing these remote messages in a transparent manner. In this configuration, using the MVS operations log (OPERLOG) as the destination provides additional benefits, because the operations log is implemented as a Coupling Facility log stream that any system in the sysplex can access.
