High Availability for ODM Rule Execution Server Console using VIPA
or most customers, having high availability (HA) for the RES console is not critical. This is because users who notice an absence of the console could ask a system administrator restart it. Furthermore, the RES console is not required for rules to run, so the rules will still execute even if the RES console is down. Also, the deployed rules won’t change, because the console could not have been used to update them; therefore, XUs will not miss any important rule updates. However, because there may be a high cost associated with a delay to rule updates, some business environments require reliable live changes. The configuration described in the following sections can help ensure high availability.
