Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

• Ensure that the AUTO_RUN flag is set to NO.
• Edit the array specific parameters. For configuring these parameters, see the following
sections based on the type of the array used in your environment.
When using Continuous Access P9000 or XP, see “Configuring primary and recovery
packages as modular packages when using Continuous Access P9000 or XP” (page 67).
When using Continuous Access EVA, see “Configuring primary and recovery packages
as modular packages when using Continuous Access EVA” (page 69).
When using EMC SRDF, see “Configuring primary and recovery packages as modular
packages when using EMC SRDF” (page 71).
3. Apply the Site Controller Package configuration file in the cluster.
# cmapplyconf -P cw_sc.config
IMPORTANT: Ensure there are no packages configured with the critical_package or
managed_package attributes in the Site Controller Package configuration file. These attributes
must be configured only after configuring the Site Safety Latch dependencies. For information on
configuring these dependencies, see “Configuring the Site Safety Latch Dependencies” (page 379).
Configuring Oracle RAC Database with ASM in a Site Aware Disaster
Tolerant Architecture
Automatic Storage Management (ASM) is a feature in Oracle Database10g and 11g that provides
the database administrator with a simple storage management interface that is consistent across
all server and storage platforms. In Continentalcluster, Oracle RAC with ASM can be configured
using the SADTA.
Figure 26 (page 143) illustrates two Oracle RAC databases with ASM that is configured in a
Continentalclusters with SADTA. Each database workload (active and passive) has its own Site
Controller Package and Site Safety Latch. The arrows in the figure indicate the package
dependencies. Figure 7-6 Sample Oracle RAC Database with ASM in SADTA The Oracle
Clusterware software must be installed at each cluster in the Continentalclusters.
