ORACLE DATA GUARD:

MAXIMUM DATA PROTECTION AT MINIMUM COST

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

• 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
