Oracle Active Data Guard 11g
This demonstrates the benefits of
using a synchronized physical standby database that is open read-only
to offload ad-hoc queries and reporting from your production database,
thus achieving fast, predictable response times for read-write business
transactions. Click on demo link to run the demo in your browser using
flash and manually advance through several introductory slides.

Data Guard Fast-Start Failover
- Automatic
Database Failover for High Availability in an MAA configuration
This demonstrates automatic
failover between an Oracle RAC primary database and an Oracle RAC
standby database in an MAA configuration. Following failover, the
original primary is automatically reinstated as a standby database, and
automatically resynchronized with the new primary database. Thus
high availability and maximum data protection are achieved during a
site failure with zero manual intervention required. The
demo automatically runs in your browser when you click
on the demo link - use the
control's at the bottom of the demo screen
if you prefer to manually advance the demo. Click here
for the accompanying presentation that includes the production
experiences of Amazon.com with Data Guard Fast-Start Failover.

E-Business Suite Site Failure - Automatic
Application and
Database Failover
This demonstrates a completely automated
site failover for an MAA configuration of E-Business Suite Release 12
running under load. Data Guard Fast-Start Failover automates
database failover. A role change trigger fires at failover time - and
executes an E-Business Suite failover script that removes the topology,
runs AutoConfig on the database and application tiers, and restarts the
application. The network is switched via a DNS push, users are
routed to the new production site and login. The
demo automatically runs in your browser when you click
on the demo link - use the
control's at the bottom of the demo screen
if you prefer to manually advance the demo. Click here
for the accompanying presentation that provides more details of the MAA
best practices utilized in this demonstration.

running under load on a two-node Oracle RAC cluster. The Oracle
instance on the first node is aborted - and the demonstration shows the
surviving instance perform recovery, Siebel Servers reconnect
automatically are are routed to the surviving instance, Oracle
Transparent Application Failover reconstructs the database sessions and
users continue processing. RAC node
failure is transparent to the Siebel user. The
demo automatically runs in your browser when you click

Siebel 8.0 Site Failover -
Automatic Application and Database Failover
Similar to the E-Business Suite
Site Failure demonstration above, this demo simulates site failure when
both primary RAC instances are powered down. Data Guard Automatic
Failover the transition of the standby database at the remote site to
the production role. The role change to production fires a
trigger that executes the Siebel failover script. Sieble Gateway,
Siebel Servers and Web Servers are started and client connections are
switched to the standby site through DNS push. The
demo automatically runs in your browser when you click
on the demo link - use the
control's at the bottom of the demo screen
if you prefer to manually advance the demo.
