Understanding the concepts and principles for high availability and zero event-loss failover with Oracle Event Processing can be daunting and sometimes confusing. During this chapter, we have described many of the aspects and various configuration options available, but to help simplify and bring together the basic requirements and implementation to get you "up and running" relatively quickly. We will now walk you through a very simple high availability configuration for the Oracle Event Processing platform.
As discussed earlier in this chapter, Oracle Event Processing supports the active/active model for high availability. In this type of configuration, a typical topology consists of a primary server and several secondary servers in the same cluster group, as you will encounter in our HA sample described in more detail below which has two servers are configured in a cluster group in a domain.
When the application is deployed to the cluster group, the...
