7.1 Overview of Reliable System Operation

The Cluster Service of BDCEP can be used to build a reliable system using PRIMECLUSTER, in order to prevent a long-term suspension of business due to hardware faults in the CEP Server.

This feature can be used to allow the events that occur after a cluster switch has completed to be processed by a CEP Server on the standby node.

Knowledge of PRIMECLUSTER is required to use the Cluster Service (refer to the PRIMECLUSTER manuals for details).

The range of application of the Cluster Service is shown below:
