Business and Technology Status 2007• Global economy is more dependent on IT than ever before• Information management is THE major mission of the

enterprise• Organizations are being pushed to ADAPT quickly to

change• Economic, Technologic, Regulatory• “At least two-thirds of all IT spending is just to sustain the business,

not to change or transform the business.”

The 11g Big Message• 11g Lowers overall costs while increasing business

and IT agility!• Simplifies your information infrastructure!• Enables change to happen while maintaining stability!• Takes management and diagnostic automation to the next

level!• Freeing key personal for higher value tasks!

• Provides the least expensive, most scalable, secure and highly available rapid application development environment!

Agility is the X-FactorAgility is the X-Factor

Defining Value Innovation• Lowers the cost while increasing Agility

• Simpler (automates/obfuscates complex tasks)• Cheaper (lower TCO via improved sustainability)• More Convenient to Use

• Most likely already own it• Solid skills base foundation• Single vendor to manage• Simplifies infrastructure landscape

• Fundamentally changes how a task or process has been done in the past

Physical Standby with Real-Time Query

Physical Standby Database

Primary Database

Real-time Queries

Continuous Redo Shipment and Apply

Concurrent Real-Time

Query

• Read-only queries on physical standby concurrent with redo apply• Supports RAC on primary / standby• Queries see transactionally consistent results

• Immediate appeal to the many users of physical standby

• DR with real time query is unique in the industry – no idle resources

• Handles all data types, but not as flexible as logical standby

Set up Test Environments using Snapshot Standbys

• Convert Physical Standby to Snapshot Standby and open for writes by testing applications

• ALTER DATABASE CONVERT TO SNAPSHOT STANDBY;

• Discard testing writes and catch-up to primary by applying logs

• ALTER DATABASE CONVERT TO PHYSICAL STANDBY;

• Preserves zero data loss • But no real time query or fast

failover• Similar to storage snapshots, but:

• Provides DR at the same time• Single copy of storage

Database Replay

• Capture Workload in Production• Capture production workload with actual load & concurrency• Move the captured workload to test system

• Replay Workload in Test• Make the desired changes in test system• Replay workload with production load & concurrency

• Analyze & Report• Errors• Data divergence • Performance divergence

• Use ADDM, AWR for further performance analysis

SQL Performance Analyzer• Focus on impact of change on SQL query workload• Capture SQL in Production

• Automatically capture SQL workload over a specified period• Capture SQL text, plans, bind variables, execution statistics• Can capture 10.2 SQL workload• Move captured SQL workload to test system

• Replay SQL in Test• Replay SQL in pre and post-change configurations• Compare and analyze performance• For regressed SQL, use SQL Tuning Advisor (10g) to improve

performance with SQL Profiles• Changes supported

• Major & minor database releases, patches, parameters, schema, optimizer statistics, tuning recommendations

SQL Performance Analyzer

SQL Plan Managementcontrolled plan evolution

Business Requirement• Data is changing over time

• Statistics and execution plans become suboptimal

• Statistics have to be updated• Possibly unpredictable changes of execution plans

• Today you have ‘freeze’ critical plans or statistics

Solution• Optimizer automatically manages SQL Plan Baselines

• Only known and verified plans are used

• Plan changes are automatically verified in maintenance window• Only comparable or better plans are used going forward

• Can pre-seed critical SQL with baselines from SQL Replay

Flashback Data Archive

• Automatically stores all changes to selected tables • Archive cannot be modified

• View table as of any time • Uses:

• Change Tracking• ILM• Long term history - years• Auditing• Compliance

DB Management Pack Enhancements

• Diagnostic Pack• ADDM for RAC• AWR Baselines• Transportable AWR

• Tuning Pack• Automatic SQL Tuning Advisor• Partition Advisor• SQL Monitoring• SPM Automatic Plan Evolution

• Oracle 9i compresses data only during bulk load; useful for DW and ILM

• Oracle 11g compresses w/ inserts, updates• Typical compression ratio of 2x to 3x• Database directly reads compressed data

eliminating decompression overhead• Strategy: compress db’s 10 largest tables

• Shrink table data by 50%, increase CPU by 5%

• Savings cascade to all db copies: test, dev, standby, mirrors, archiving, backup, etc.

Data Compressionfor All Applications

Oracle SecureFilesHigh-Performance Large Objects

• High-performance transactionalaccess to large object data• documents, medical, CAD, imaging …

• low-latency, high throughput, concurrent access
