  1. Non-stop computing 學 生:R90725004 黃錫煙 :R90725007 黃春照 指導教授: 莊 裕 澤 教授

  2. Agenda • E*Trade Case Study • Oracle9i Real Application Cluster • Sun Cluster [TM] 3.0 architecture • Sun Cluster [TM]3.0 management • Conclusion • Reference

  3. Strong management, marketing and technology teams from world leaders such as Schwab, Fedex, Chase, Visa. VP of Engineering: 10 years VISA system development and operation experience 10 Core development engineers are also from VISA, have the know-how of building high volume transaction systems Web creative team: experienced in developing attractive and user-friendly web interface for on-line trading E*Trade Team

  4. Customer retention service personalization information customization dynamic content generation Peak load handling There is no way to control the internet user base There is no way to control concurrent users System must be able to scale up quickly to meet growing customer base No trade drop Highly reliable system Disaster recovery capability Transactional integrity E*Trade Challenges

  5. Must bring out new products and services quickly to meet market demand and stay ahead of the competition a flexible architecture a rapid development environment Integration with partner offerings 3rd party integration capability 24x7 availability No service downtime even when new services are launched No service downtime even when new hardware are added Innovative off-hour services E*Trade Challenges

  6. 100% Replace the existing CGI based Stock Trading services with NAS and Java based Solutions Over 10 groups, about 70 people working on NAS based projects. US Stock Trading Risk management Research tools Portfolio management tools Advertisement Customer Care Marketing Professional Edge Smart Alert Content Alliances … E*Trade - Today

  7. Scalable and High Performance: multi-tier architecture simulated 100,000 simultaneous concurrent users Open: works with but not lock in with any hardware platforms, DBs or clients Highly available: redundant on-line systems plus two identical data centers Reliable: even if the west coast data center is down, the incomplete transactions will be rolled over to the east coast data center over a WAN to continue the execution Flexible: layered, modularized application design new service launch every two weeks easy partner offering integration E*Trade - Today

  11. Faster Database Software Run Database on Multiple Computers Faster Database Computer More Processors –2x64 or 32x4 Faster Processors –4 @ 700 MHz No Single Point of Failure Oracle9i Cluster Strategy

  12. Database Software on Multiple Computers Very Hard to do for Real Applications Everyone did it for Benchmarks – TPC-C Only IBM Mainframes did it forReal Applications Oracle9i Cluster Strategy

  13. Shared DiskRuns Real Applications IBM DB2 for Mainframes Oracle9iDB Shared Nothing Only Runs Benchmarks IBM DB2 UNIX & Windows Microsoft SQLServer Oracle9i Cluster Types Data A-Z Data A-E Data F-K Data L-S Data T-Z

  14. Runs No Existing Applications You Must Write Custom Applications Gets Less Reliable As You Add Computers Multiple Single Points of Failure Very Hard to Manage You Must Re-Partition Data To Add Computers Oracle9i Shared Nothing Clusters IBM UNIX & Windows, MS SQLServer
