  9. Capacity • Capacity = 240 users • 70,000+ students at U of M

  10. Improvement Needed • Poor performance • Instability • Students hated the system • Support staff restart systems all day • Can’t do other work!

  11. Poor Performance • Students see “Access denied” • 10-30 seconds add/drop time = “good” • 2 minutes not unusual

  12. Instability • Multiple crashes per day • One crash induces another to fail • All servers are down!

  13. Staff Morale • Incentive to improve things for ourselves • Stability and performance are key • Separate effort to improve PS performance • Unable to improve web application capacity issues • Registration cycle starts in 2 months!

  14. The Culture

  15. Culture • Creative atmosphere • Encourage experimentation • Performance-based vs. clock-puncher • Web is an open book

  16. Culture • Games • Fun • Reward • Recognition

  17. Culture • Staff are responsible, professional • Innovative thinking! • Gets results!

  21. Web Registration (AIX)

  22. Web Registration (Linux)

  23. Web Registrationon Linux? • Linux runs well on IBM hardware • IBM support for all components • Server management tools: • RPM, Kickstart • Ensure Linux hardware compatibility before you start: • SCSI, network, video

  24. Requirements • Support for all components • Stability • Scalability

  25. Web Registration (AIX)

  26. Web Registration (Linux)

  27. Options • Web registration tied to Web Sphere • Web Sphere supported on these platforms: • AIX • Solaris • Windows NT • Red Hat Linux • Linux is best choice for short timeframe

  28. Project Management

  29. Project Team • A multi-team effort • Web Development: • Systems Administrator • Manager • Central Computing: • Hardware

  30. How To Implement To Build Confidence • Change as little as possible • Test before you implement • Burn-in period • Phased deployment • Isolate moving parts

  31. Project Management • Keep the project in scope • Budget • Time frame • Features vs. effort

  32. Project Management • Create a schedule, stick to it • Regular meetings for progress • Emails with daily status • Be honest with respect to risks, delays

  33. Overcoming Fear • Challenge to the status quo • Free / open source is new concept • New paradigm • CIO • Customer • Security staff • Our own staff • Auditors

  36. Results

  37. Performance Improved • (AIX) Web registration: • 10-30 seconds response time = “good” • 2 minutes not unusual

  38. Performance Improved • (Linux) Web registration: • 74% 0-5 sec. Add/drop • 95% 0-10 sec. Add/drop

  39. Stability Improved • (AIX) Web registration: • Multiple crashes per day • All servers down not uncommon(“cascade failure”)
