"The clustered pool of storage managed by
the ASM feature in Oracle Database 10g
Release 2 presents new key opportunities for
Vanderbilt to improve storage utilization and
save money through database storage
consolidation in a single instance Oracle
Database 10g as well as Real Application
Clusters (RAC) environments"

“Airbus testing of Oracle Database 10g
Release 2 Data Guard Fast-start Failover
produced impressive results. Failover
executed automatically without manual
intervention in less than a minute. This
was much faster than a cold failover using
third party cluster technology.”
- Werner Kawollek

Airbus Deutschland GmbH
“Data Guard's rolling upgrade capability is
amazing. Airbus tested upgrading from Oracle
Database 10g Release 1 to release 2 using this
feature. The elapsed time for the database upgrade
was about 3 hours. But applications were available
for all but less than 2 minutes while a Data Guard
switchover was executed, quickly transitioning
production from the previous database release to
Oracle Database 10g Release 2.”

“Oracle Database 10g Release 2 offers significant
new automations that make database
management even easier. New features such as
Automatic Segment Advisor and Dynamic Metric
Baselines, to name a few, make my job
considerably easier and allow me to focus more
on strategic business IT issues and less on
mundane day-to-day database management
activities”
