9 Automatic SQL Tuning Nightly Packaged Apps Well-tuned SQL Customizable Apps Automatic SQL Tuning SQL Profiling SQL Profiles Test Execute Implement Automatic High-Load SQL AWR Index, Stats, Structure Analysis Advisor Report Manual Automatically chooses high-load SQL based on response time, throughput and frequency criteria Automatically tunes SQL by creating SQL Profiles Automatically test executes the tuned plans to verify improvement Automatically implements greatly (3X) improved plans (optional) Automatically reports missing access structures, stale stats, poorly structured SQL Automatically runs during maintenance window or manually triggered

10 Automatic Memory Management O/S Memory SGA PGA O/S Memory SGA PGA Unifies system (SGA) and process (PGA) memory management Single dynamic parameter for all database memory Automatically adapts to workload changes Maximizes memory utilization Helps eliminate out-of-memory errors

11 SQL Plan Management SQL Plan Management is Controlled Plan Evolution Allow SQL plan changes, but only for the better! Optimizer selects a new plan only after verifying it performs better All new plans are automatically or manually verified by test executing them Better performance verified plans are stored in SQL Plan Baseline Using SQL Performance Analyzer (SPA) to pre-seed baseline with good plans for critical SQLs before making changes

12 <Insert Picture Here> Change Assurance

13 Change is the only Constant Change is the most common cause of instability Enterprise production systems are complex Actual workloads are difficult to simulate Possible! Realistic testing before production is impossible Reluctant to make changes Unable to adopt new competitive technologies Preserve Order Amid Change

14 Lifecycle of Change Management Test Make Change Diagnose & Resolve Problems Set Up Test Environments Provision for Production Identify Patches & Workarounds Diagnose & Manage Problems Real Application Testing

15 Adaptive Change Assurance Real Application Testing Technology benefits Rapid technology adoption Higher testing quality Business benefits Higher agility Lower risk & cost Test Change Remediate Deploy Solution for the Agile Business

16 Real Application Testing Features Database Replay SQL Performance Analyzer Change assurance for: Database and O/S upgrades Configuration changes, e.g., conversion from single instance to Oracle RAC Storage changes O/S migrations, e.g., Windows to Linux

28 Incident Packaging Service

29 Online Patching of One-off Patches Oracle already supports rolling patches between nodes in a cluster The next major release adds online patching of a running Oracle executable (single instance or cluster) with no downtime Integrated with OPatch Many one-off patches can be hot patched Great for diagnostic patches Initially available on Linux and Solaris Long term goal is online patching of Critical Patch Updates (CPUs).

30 Reliable Deployment with Patch Automation Apply patch Alert DBA Download Patch Proactively search for patches relevant to customer environment Yes 1-off patch becomes available Relevant Patch Found? Proactive patch advisories from Oracle Metalink Acquisition of the patch based on installation s configurations and feature usage Stage once in the software library for multiple deployments Best practice driven patching Rolling patching support for RAC/ASM/Clusterware

31 <Insert Picture Here> Oracle Database Scalability and Performance

32 Major New Performance Innovations SecureFiles New generation LOBs just as fast as files Table Compression Now for OLTP as well as DW applications Query Results caches Fast caching of query/function results for read-mostly data Next Generation RAC Cache Fusion Even more scalable

33 Oracle SecureFiles Consolidated Secure Management of Data Many applications have both files and relational data e.g. Document Management, Medical, CAD, Imaging SecureFiles breaks the performance barrier that has kept file data out of databases Similar to LOBs but much faster, and with more capabilities Transparent encryption, compression, deduplication, etc. Preserves security, reliability, and scalability of database Superset of LOB interfaces for easy migration from LOBs Benefits Single security model Single view of data Single management of data High performance

34 Compression for Mainstream Oracle 9i compresses table data only during bulk load Data warehousing, ILM Table compression is now viable for all applications Compress during random updates Typical compression ratio of 2x to 3x Database directly reads compressed data bypassing decompression overhead Strategy - Compress 10 largest tables in a database Reduce table data by half, increase CPU usage 5% Savings cascades into test, dev, standby, mirrors, archiving, backup, etc.

35 Server Results Cache taking the buffer cache to the next level Automatically Caches results of queries, query blocks, or pl/sql function calls Cache is shared across statements and sessions on server Significant speed up for read-only / read-mostly data join Q2: Q1: Use build it query transparently cache join GBY T1 GBY cache join join T4 join T2 T3 T5 T6

36 OCI Consistent Client Cache like cache fusion between server and client Application Server Database Caches query results on client Improves performance for read-mostly tables Faster response time - eliminates network round trips Saves server CPU Consistent with server Cache proactively refreshed when result set changes Maximum age of consistency info can be set
