  4. What is uPortal? • Enterprise, horizontal portal • Framework for presenting aggregated content (channels) • Personalization • Role-based access control • Open source, collaborative effort • Java web application • XML transformations (XSLT) CUMREC 2001 • Ken Weiner, IBS

  5. Where does uPortal fit? People Browsing Devices uPortal with Channels Data Applications CUMREC 2001 • Ken Weiner, IBS

  6. What is a Channel? • Displays content • XML feeds • Rich Site Summary (RSS) • Legacy system • An interactive application • Bookmarks • Email CUMREC 2001 • Ken Weiner, IBS

  7. Flexible Layouts • Structures • Tab / column • Tree / column • Themes • Multi-column • Multi-row • Skins • Matrix, Java CUMREC 2001 • Ken Weiner, IBS

  8. Content Transformation XML XHTML: Web Browser XSLT Processor HTML: PDA Stylesheet WML: Cell Phone CUMREC 2001 • Ken Weiner, IBS

  9. Tab / Column Layout CUMREC 2001 • Ken Weiner, IBS

  10. Tree / Column Layout CUMREC 2001 • Ken Weiner, IBS

  11. Multiple Target Devices CUMREC 2001 • Ken Weiner, IBS

  12. Interfaces Facilitate Implementation Interface Is Alice a faculty member? Alice wants to see the faculty calendar. or Look in our LDAP directory Contact ourHR application Implementations CUMREC 2001 • Ken Weiner, IBS

  13. uPortal Interfaces • Authentication • Proving your identity • Authorization • Deciding what you can access • User preferences • Profiles, structure, themes, skins • Channel information • Availability and configuration CUMREC 2001 • Ken Weiner, IBS

  15. What’s new in 2.0? • Abstraction of layout • Structure/theme transformations • Standard channel events • Standard CSS classes • More flexible publish/subscribe • User profile management • JNDI lookup service • WebProxy channel CUMREC 2001 • Ken Weiner, IBS

  16. Coming Soon • Layout-specific userpreferences management • Fully-normalized database • Support for “Wallet” authentication • Integration of vendor content • More support for cell phonesand palm pilots CUMREC 2001 • Ken Weiner, IBS

  19. Going Live with JA-SIG’s uPortal Dave Frazer Associate DirectorITServicesThe University of British Columbia CUMREC 2001 • Ken Weiner, IBS

  20. myUBC • How it began • Why uPortal • Implementing the Reference code • Sharing our Experience CUMREC 2001 • Ken Weiner, IBS

  21. University of BC • 35k FTE students • R1, Medical and Professional • #2 in Canada • Located in Vancouver CUMREC 2001 • Ken Weiner, IBS

  22. How it All Began • Access to information • Collaborative Initiative • JA-SIG • uPortal Initiative • Hit the ground running CUMREC 2001 • Ken Weiner, IBS

  23. Attractions and Opportunities • Technologies • Open Source • Small • Clean, flexible, processing model • The Portal Promise • JA-SIG CUMREC 2001 • Ken Weiner, IBS

  24. Challenges • Technologies new to us • Developers reference implementation • Unknown performance • Unknown robustness • Unknown reliability • Deciding what functionality to deliver CUMREC 2001 • Ken Weiner, IBS

  25. What gave us the confidenceto proceed? • Useful, but not critical function • Release date important but not critical • Gradual release strategy • Experienced development team • Proven existing infrastructure • BEA WebLogic Server • Oracle RDBMS • Sun E450 hardware CUMREC 2001 • Ken Weiner, IBS

  26. The major problem we faced Can we turn a reference implementaton into a production service? CUMREC 2001 • Ken Weiner, IBS

  27. Reference Implementations and Prototypes • Demonstrate correct behaviour • Environment is predefined • Environment is assumed clean • User behaviour expected to be reasonable • Database assumed clean and maintained • The 20% of the code that does correct things CUMREC 2001 • Ken Weiner, IBS

  28. Production Services • Reasonable behaviour in an existing environment • Wide audience • Must behave reasonably all the time • Databases must be maintained • Need other 80% of the code CUMREC 2001 • Ken Weiner, IBS

  29. What we did to address the problem • Froze the repository code • Ported to the Oracle RDBMS • Adapted to local authentication • BEA WebLogic Servlet/JSP engine • Team experienced in OS development CUMREC 2001 • Ken Weiner, IBS

  30. Other Challenges • New technologies • Selecting channel functionality CUMREC 2001 • Ken Weiner, IBS

  31. First Experiences • In theory, theory and practice are the same. In practice, they are different • Our first scaling problems • Database problem recovery • Database out of service • Channels out of service CUMREC 2001 • Ken Weiner, IBS

  32. How did we achieve control? • Few, well-behaved channels • Minimal dependence on external resources • Enhancements to database recovery • Substantial hardware platform • Avoided experimental changes • Gradual release strategy CUMREC 2001 • Ken Weiner, IBS

  33. How successful were we? • Users happy • Confident we can grow • New content limitations • Forked from reference code • Learned a lot CUMREC 2001 • Ken Weiner, IBS

  34. What we should have done(according to the rules) • System testing • Volume testing • User environment testing • Stress testing • Load testing CUMREC 2001 • Ken Weiner, IBS

  35. We were lucky No wildly chaotic behaviours or hotspots were observed CUMREC 2001 • Ken Weiner, IBS

  36. Would we do it differently? Given our goals and requirements - … Probably not CUMREC 2001 • Ken Weiner, IBS

  37. What’s Next? • Development of 2.x • 1.0 -> 1.6 -> 2.x • install myUBC server • Implement more content • Do the testing • Target all students in Sept CUMREC 2001 • Ken Weiner, IBS
