Disaster recovery rehearsal in Continentalclusters

Figure 1: DR rehearsal in Continentalclusters

A command (cmdrprev) to preview the data replication storage failover in Metrocluster with

Continuous Access EVA, Metrocluster with Continuous Access for P9000 and XP, and Metrocluster

with EMC SRDF is provided. The command can be run on either the primary cluster nodes or the

recovery cluster nodes at any time to identify errors in the data replication environment. The command

does not require any preparation and is non-intrusive (i.e., does not modify the environment).

This white paper illustrates the DR rehearsal implementation for a Single Instance application,

Oracle 9i RAC, and Oracle 10g RAC application that is currently set up in Continentalclusters.

Note: The DR rehearsal feature is not supported for the complex workload packages configured using SADTA.
