How does Oracle Database 10g increase overall customer application availability?
Oracle Database 10g increases availability by providing technologies designed to protect applications from system failure such as Oracle Real Application Clusters. Oracle Data Guard provides protection from data loss by managing a standby database for your primary database. This provides protection from disasters, human errors, data corruption and reduces planned downtime by enabling an operator easily switchover operation to a standby for routine maintenance. Oracle Database 10g further increases uptime by allowing many administration operations to be done while the database is in productive use such as online table redefinition, index builds, PL/SQL package maintenance and dynamic reconfiguration.
