Continentalclusters Version A.05.00 Release Notes
What’s In this Version
Chapter 16
Support for the Capability to Select a Specific Oracle
RAC instance for Initial Startup, Shutdown, or
Failback at the Primary Site
Instead of operating on all of the RAC instance package sets, a new
option “-i” is provided in the Continentalclusters tool
/opt/cmconcl/bin/ccrac_mgmt.ksh to offer the selection of a specific
set of Oracle RAC instance packages to be started, halted, or failed back
at the priamry site.
The tool ccrac_mgmt.ksh must not be used at the recovery site for a
recovery purpose. (The cmrecovercl command is used in this case) This
tool is used for the initial startup, shutdown, or fail back of the RAC
instance packages at the primary site.
Continentalclusters Product Features
The Continentalclusters product has the following basic features:
• Continentalclusters works with any type of data replication. A set of
guidelines for integrating your data replication technology can be
found in chapter 4 of the Designing Disaster Tolerant High
Availability Clusters manual on http://www.docs.hp.com.
Continentalcluster provides a pre-integrated data replication
solution using HP StorageWorks Continuous Access XP, Continuous
Access EVA or the EMC/ SRDF with the separately puchased
products Metrocluster CA XP, Metrocluster Continuous Access EVA
and Metrocluster/SRDF. An alternative to using the pre-integrated
data replication solution a customer-selected data replication
solution can be chosen by following the integration guidelines.
• A recovery pair in a Continentalclusters consists of one primary
cluster and one recovery cluster. One or more recovery pairs can be
configured in a continental cluster. Failover of a specific package
occurs in one direction from the primary cluster to the recovery
cluster. Each data center can serve as both primary and recovery
cluster for different packages. In the cascading failover
configuration, the primary cluster can be a metropolitan cluster
using EMC/SRDF or CA XP.
