When approaching scalability and high availability, many people often discuss them with a goal to accomplish both at the same time but often use these words and concepts interchangeably. While the presence of state in Oracle Event Processing can make it more challenging to tackle these issues concurrently, particularly HA, we will now discuss how these requirements can be addressed and successfully implemented.
Like any computing resource, Oracle Event Processing servers can be subject to both hardware and software faults that can lead to temporarily unavailability of services and/or loss of data. OEP high availability features give you the capability to mitigate both of these possibilities at a level of reliability that suits your application requirements.
OEP supports an "active/active" high availability architecture; meaning the additional servers in the architecture are in an active state in the event that there is a failure, but both (or all of the...
