Mission-Critical Business Continuity and
Disaster Recovery for Oracle
• High Availability: Active/active data centers with zero
RPOs and RTOs
• Disaster Recovery: Cost-effective DR for
active/active data centers with point-in-time data
recovery at a third, remote site
VPLEX
24/7 application availability
Simplified high availability management
Automatic failure handling & load balancing
Zero downtime maintenance
Simplified deployment of Oracle RAC on
Extended Distance Clusters
Protection for multiple databases or application
files as a unit with consistency groups
Increased infrastructure utilization

Oracle Database Architecture
 Oracle components
– Oracle Database 11g Release 2 Enterprise Edition
– Oracle ASM
– Oracle Clusterware
 Oracle Extended RAC over VPLEX
– Simplified management
– Hosts connect only to their local VPLEX cluster
– Hosts send I/O only once to the local cluster – dual writes not
required
– No need to deploy Oracle voting disk and Clusterware on a third
site
– Eliminates costly host CPU cycles consumed by host-based
mirroring
– Protects multiple databases and/or applications as a unit

RecoverPoint Replication – Overview
Tests

Create a bookmark (named snapshot).

Recover database at Site C to bookmarked point in time.

Verify integrity of recovered database.

Fail over production from Site A to Site C.

Update database on Site C (now the production site).

Recover database at Site A to bookmarked point in time.

Verify integrity of recovered database.
