Is this application near any critical SLA

threshold?

Do I need to adjust parameters on this

machine?

Do I need to adjust the memory grid?

Can I better optimize grid across all applications?

Case Study: Large Web Application

Problem

• Controlling IT costs by moving away from one-off purchasing• Eliminating downtime that can cost the company thousands

of dollars per minute• Implementing upgrades seamlessly

Scenario

• High-volume consumer-facing transactional Web application with high growth

04/07/23 38©2008 Oracle Corporation

Profile

• Large Web-based social networking app

• 17 million registered users

• 10,000+ new users daily

Application Grid

• Standardized hardware

• Use of WebLogic Server clustering for scale out

• Standardized WebLogic Server nodes replicated through WLST scripting

• Looking at JRockit and Coherence

Solution

• 40-node cluster of WLS 10 for main site• Provides dependable high availability• Extensive use of WLST scripting to achieve

grid-like provisioning• Side-by-side app deployments to allow for smoother

app upgrades• Improve customer satisfaction with superior performance

Getting StartedThere are some easy early wins!

• Identify areas of greatest pain• Inefficiency• Inflexibility• Performance/reliability

• Identify areas of greatest opportunity• Where small improvements get big returns• Where existing infrastructure already supports some “gridness”

• Build a plan• Short term: leverage existing grid enablement• Short-Medium term: augment with better grid infrastructure• Medium-Long term: build out application grid across data center
