Demonstrated Truths

• Optimized Database Tuning Provides– Better Response Times– Improved Ability to Add more Users– Lower Energy Consumption

Seeing is BELIEVING• San Mateo IIC

– IBM p570 with 16 CPUs, 36 GB Memory– DB2 LUW 9.5.3 with Automatic Tuning

Enabled– IBM Tivoli for Energy Management

• DBI Brother-Panther® – Rapidly ISOLATES performance issues– Automates optimized solutions– Trend Charts verify Tuning Success

7

PROOF• Show Power Used @ CPU idle• Drive CPUs to 100% busy by simulating 100+

OLTP Web Users– Show SQL & TX Response Times

• Show Power Used @ 100% CPU busy• Tune Database with Brother-Panther• See RESULTS

– Lower CPU Utilization– Measurably Lower Power Consumption– SQL & TX Response Time Improvements

Scalability Demonstrated

• MORE PROOF– With CPU Capacity Restored, we’ll add more

users!– Database Tuning Facilitates Server

Consolidation & Virtualization • More “Well Tuned” virtualized database servers

can be located within a given Frame

Myth Busters

• Throwing Money at more CPUs won’t solve performance & scalability problems if the database isn’t properly tuned

• Database AUTOMATIC Tuning only REACTS to workloads to COMPENSATE for inadequate tuning– Only proper tuning achieves optimization at

lowest possible costs

36

Your Choice?

• 24% Higher Energy Costs

• Higher Hardware & Software Costs

• Slow Response Times

• Poor Productivity

• Lower Energy Costs for Servers & A/C

• Lower Hardware & Software Costs– Consolidate more

servers!

• Sub-Second Response Times

• Improved Productivity

37

Your Choice?HIGH COSTS, INADEQUATE PERFORMANCE

LOW COSTS, HIGH PERFORMANCE

38

The Ripple Effects of DatabasePerformance Tuning & Optimization…

• Queries Run Faster• Faster Transactions > People > Business• Faster Decisions > Agility• Improved Productivity

• Lower Cost/TX and CPU Utilization• Lower Energy Costs• Greater Performance Predictability & Reliability• Defer/Avoid Unnecessary Hardware Upgrades• Enable Successful Server Consolidation &

Virtualization
