Figure 1-5 Replicated Enqueue Clustering for ABAP and JAVA Instances

Figure 1-5 shows an example configuration. The dedicated failover host can serve many purposes during normal operation. With the introduction of Replicated Enqueue Servers, it is a good practice to consolidate a number of Replicated Enqueues on the dedicated failover host.

These replication units can be halted at any time without disrupting ongoing transactions for the systems they belong to. They are ideally sacrificed in emergency conditions in which a failing database and/or Central Service Instance need the spare resources.
