EVA, and Metrocluster with EMC 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 with a common recovery 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 Continuous Access XP.
• Logical data replication is also possible using the Oracle Standby
Database. Template files and additional information are included in
the Oracle Standby Database portion of the Enterprise Cluster
Master Toolkit product (a separately purchased product). Other
customer-selected logical data replication solutions can be
implemented as well.
• Cluster monitoring is carried out over LAN or WAN connections. Use
any LAN or WAN connection; however, some data replication
methods may require high speed connections such as T1, T3, E3/ES
or ATM leased lines or switched lines.
