Data Protection


Comprehensive Data validation and

protection

• Built-in checks detect and repair corruptions

– In data and redo blocks using checksum validation

– Detects writes acknowledged, but actually lost by the I/O subsystem

• Various levels of checks configured by administrators

– Choose the desired protection level (data / data + index blocks)


• Virtualize and shares storage resources

• Online addition and migration of storage

• Advanced data striping for maximum I/O performance

• Mirroring protects from disk failure

Automatic Storage ManagementLow-cost protection from storage failure


Oracle Recovery Manager Ensures valid database backup and restore

• Intrinsic knowledge of Oracle database file formats and

recovery procedures

– Block validation

– Online block-level recovery

– Unused block compression

– Online, multi-streamed backup

• Fully Integrated with:

– Oracle Secure Backup

– 3rd party backup tools


Data Recovery AdvisorReducing downtime by eliminating confusion

• Automatically diagnoses data failures

• Intelligently determines recovery strategies

– Aggregates failures for efficient recovery

– Presents only feasible recovery options

– Indicates any data loss for each option

• Can automatically perform selected recovery steps

– Using Recovery Manager or Enterprise Manager

• ‘Flashback’ operates on changed data only

• Reduces correction time from hours to minutes– Correction Time = Error Time + f(DB_SIZE)

• Simple to use command instead of complex procedures

• Applies to all types of user errors

• Run all databases for all applications on shared platform

• Adapts to changes in workloads

• Highly available and scalable

• No changes required to applications

• Trimmed-down RAC One Node forr non-critical databases

• Dynamically assigns databases to groups of servers

• Unassigned servers go to spare pool

• Policy managed with Min/Max & relative importance

• Cluster reconfigures if a pool falls below its minimums

Oracle Data Guard Protecting from Site Failure

• Best corruption protection for Oracle Database

• Automatic failover to standby database

• Software code path on standby different than primary

• Multiple Oracle corruption detection checks

Data Guard


Zero Data Loss Over Long DistanceData Guard DR sweet spot

• Far enough to avoid regional disaster

• Close enough for zero data loss

• Uses order of magnitude less network messaging than disk-based remote mirroring solutions

Data Guard


up to 300 miles

• Standby database in simultaneous read and recovery mode

• Offload read-only queries to an up-to-date physical standby

• Use fast incremental backups on a physical standby

Edition-based RedefinitionNew in Oracle Database 11g Release 2

• Enables online application upgrade

• Code changes installed in the privacy of a new edition

• Data changes are made safely by writing only to new

columns or new tables not seen by the old edition

• An editioning view exposes a different projection of a

table into each edition to allow each to see just its own

columns

• A crossedition trigger propagates data changes made

by the old edition into the new edition’s columns, or (in

hot-rollover) vice-versa

Republic of Turkey Ministry of Justice

• Ministry of Justice of Turkey has established one of the most eco-efficient e-justice systems in the world, enormously reducing the

amount of paper used, carbon emissions and movement of people in the Turkish judicial system

• Reduced dramatically the processing times for legal cases, statistics, and correspondence—from hours or days to a few minutes

• Developed a centralized e-learning system that has educated 57,000+ employees to date inside the Turkish judicial system

• The SMS information system reduces CO2 emissions by minimizing movement of people , goods and the use of office supplies

• Saving 460+ tons of paper, 14,000+ tons of water, 800,000+ liters of fuel oil annually, compared to a paper-based environment
