ORACLE WHITE PAPER | SEPTEMBER 2016

Introduction

Oracle Database Appliance is a pre-built, pre-tuned, and ready-to-use clustered database system that includes

servers, storage, networking, and software in an optimized configuration that makes it easy to deploy, operate,

and manage. It is a complete and ideal database platform for small, medium, and large sized implementations

and incorporates robust, time-tested Oracle technologies, including the world leading Oracle Database, the best

selling Oracle Real Application Clusters (RAC) database option, Oracle Clusterware, and Oracle Automatic

Storage Management. By integrating hardware and software, Oracle Database Appliance eliminates the

complexities inherent in non-integrated, manually assembled solutions, reducing deployment time from weeks or

months to just a few hours, while preventing configuration and setup errors that often result in sub-optimal, hard-

to-manage database environments.

Why do I need a standby database environment?

While the Oracle Database Appliance is a highly available system in itself, a standby database environment can

provide protection against planned and unplanned downtime as well as against data loss in case the primary

database environment becomes unavailable. With the use of proper technology, it is also possible keep the

standby database synchronized with the primary database, thereby providing almost transparent continued

database operations in the event of planned maintenance such as system patching to problems ranging from

user errors to system failures, to disasters. A standby database has therefore always been a key to high

availability and protection for any important production system.

Oracle recommends using a separate, dedicated Oracle Database Appliance system to host the standby system

for a mission critical production system running on the primary Oracle Database Appliance system.

Why Oracle Data Guard?

Oracle Data Guard is the recommended disaster recovery solution to protect databases residing on Oracle

Database Appliance against database or cluster failures, data corruptions, disasters, and user errors resulting in

“sick” or down database. The tight integration of Oracle Data Guard with Oracle Database provides a unique

level of data protection that is impossible to achieve with any other solution. Oracle Data Guard is available to

customers as part of Oracle Database Enterprise Edition. It is easy to deploy and provides the management,

monitoring, and automation software to create and maintain one or more synchronized copies (standby

databases). Oracle Data Guard helps maintain database availability easily when the production database system
