AGENDAAGENDA
• Oracle Data Guard – a Quick Introduction
• Data Guard Features in Oracle Database 10g
• Customer Success Story – Sun Microsystems
• Summary & Q/A

WHAT IS ORACLE DATA GUARD??
• Oracle’s disaster recovery solution for Oracle data
• Feature of Oracle Database Enterprise Edition
• Automates the creation and maintenance of one or
more transaction ally consistent copies (standby) of the
production (or primary) database

ORACLE DATA GUARD FOCUSORACLE DATA GUARD FOCUS
• Data Failures & Site Disasters:Data Failures & Site Disasters:
• Also addresses human errors & planned maintenances
– Data Protection
– Data Availability
– Data Recovery
Data is the core asset of
the enterprise!All 3 are important!

 Logical Standby Database is an open, independent, active database
 Contains the same logical information (rows) as the production database
 Physical organization and structure can be very different
 Can host multiple schemas
 Can be queried for reports while logs are being applied via SQL
 Can create additional indexes and materialized views for better query performance

WHY ORACLE DATA GUARD?WHY ORACLE DATA GUARD?
1.1. Disaster Recovery & High AvailabilityDisaster Recovery & High Availability
• Easy failover/switchover between primary and standby databasesEasy failover/switchover between primary and standby databases
2. Complete data protection
– Enables zero data loss, safeguard against data corruptions
3. Efficient utilization of system resources
– Standby databases can be used for reporting, backups, queries
4. Balance data availability against performance
– Flexible data protection/synchronization modes
6. Centralized and simple management
– Push-button graphical interface for management and monitoring
5. Automatic resynchronization after restoration of network connectivity
– Automatic archive gap detection and resolution with no manual intervention
