  4. The Big 4 Features in 11g • Real Application Testing • Advanced Compression • Active Data Guard • Total Recall

  5. Analysis & Reporting Real Application Testing – Database Replay • Recreate actual production database workload in test environment • Identify, analyze and fix potential instabilities before making changes to production • Capture Workload in Production • Capture full production workload with real load & concurrency info • Move the captured workload to test system • Replay Workload in Test • Make the desired changes in test system • Replay workload with production load & concurrency • Honor commit ordering • Analyze & Report • Errors • Data divergence • Performance divergence

  6. Production ( 9.2.0.8) Test (  11.1) Clients … Replay Driver * Mid-Tier Linux … Windows Storage ASM File System Storage Transfer Replay Analysis & Reporting Capture Database Replay Workflow Pre- Process

  7. SQL Performance Analyzer Predicts impact of change on SQL response time Assess change by executing query part of SQL in isolation without concurrency Unit testing of SQL, e.g., optimizer stats/config, drop index, etc. Can use for upgrades from 9.2/10.1 10.2 or 11g 10.2 10.2 or 11g Database Replay Predicts impact of change on workload throughput Assess change by replaying workload with concurrency Comprehensive testing of DB stack, e.g, memory, RAC, concurrency related Can use for upgrades from 9.2 or 10.2 11g Real Application Testing • Real Application Testing = SPA + Database Replay • SPA + Database Replay are complementary • Together, provide comprehensive & flexible testing solution

  8. Snapshot Standby – Leverage Standby Database for Testing Physical Standby Apply Logs • 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 • No idle resources • Similar to storage snapshots, but: • Provides DR at the same time • Uses single copy of storage Open Database Back out Changes Snapshot Standby Perform Testing Continuous Redo Shipping

  9. The Big 4 New Features in 11g • Real Application Testing • Advanced Compression • Active Data Guard • Total Recall

  10. Advanced Compressionin Oracle Database 11g • Comprehensive set of data compression capabilities • Structured ( inline ), unstructured ( zlib ), rman ( zlib ), • network transport ( zlib ), datapump ( bzip2 ) • Reduces storage consumption by 2 – 3 times • Savings cascades into test, dev, QA, backup, DR environments • Enhances memory and network efficiency • Complete application transparency • Benefits diverse application workloads • Transaction Processing • Data Warehousing • Content Management Up To 3X Compression

  13. Data Guard 11g Stop redo apply at 8am Open read-only for queries Active Data Guard Option Redo apply is always on Always open read only Data Guard vs Active Data Guard • By 4pm, data is 8 hours old • Queries and reports always see latest data • Any failover will be delayed due to backlog of data that must be applied • Failover is immediate when needed, standby database always up-to-date

  16. Managing Data History – Current Approaches • Application or mid-tier level • Combines business logic and archive policies • Increases complexity • No centralized management • Data integrity issues if underlying data is updated directly • Database level • Enabled using Triggers • Significant performance and maintenance overhead • External or Third-party • History stored in separate database • Cannot seamlessly query OLTP and history data

  17. Introducing Flashback Data Archive • Seamless access to archived historical data • Using “AS OF” SQL construct select * from product_information AS OF TIMESTAMP '02-MAY-05 12.00 AM‘ where product_id = 3060 • History is stored in automatically created history tables inside the archive • History is captured asynchronously by new background process (fbda)
