1. June 13 – 15, 2010 Project Cloud 9 a z-Powered Learning Environment by Michael Lavacca, Sean Goldsmith, Deyaa Abuelsaad, and Sean Dunn MARIST/IBM Joint Studies

2. June 13 – 15, 2010 Our Goal The enablement of the Sakai application on IBM’s WebSphere Application Server and DB2 software, and the System Z Mainframe.

3. June 13 – 15, 2010 3 Sakai is an “adaptable, interoperable, reliable, scalable, and flexible enterprise application that supports teaching, learning and scholarly collaboration.” The Sakai Community develops and distributes the open-source Sakai CLE, an enterprise-ready collaboration and courseware management platform that provides users with a suite of learning, portfolio, library and project tools. Sakai’s open approach allows institutions to deploy, host and modify What is Sakai? the software in whatever manner best supports the institutions skills, needs and goals. Sakai’s open development process allows local enhancements to be incorporated into future versions of the software.

6. June 13 – 15, 2010 C HALLENGES What did we overcome to achieve our goal?

7. June 13 – 15, 2010 7 Challenges Sakai 2.6 was a ‘moving target’ Our contributions affected multiple components Approximately 60 issues –4 critical, 45 major, 8 minor, 3 trivial Issues –Differences between Sun JRE and IBM JRE –Differences between Tomcat and Websphere Integrating with rSmart’s DB2 work Resolved issues via coding or configuration changes

8. June 13 – 15, 2010 8 Project Timeline (dates are 2008-2009 unless otherwise mentioned) Notified Sakai Foundation about our goal to implement Websphere and DB2 support (2/28) Created JIRA to track feature (4/21) Created screencast (5/29) Created Sakai Confluence section (6/13) Bootcamp (6/6) Initial test of Sakai on Websphere (6/13) Announced on Sakai devlist (6/17) Submitted CCLA and CLA and gained IBM OSSC approval Development - Continuous testing and bug fixing (6/16-9/17) Called for vote on Sakai devlist for merge (9/18) Accepted and merged (9/23) Code Freeze (9/29) QA and bug fixes (10/01/08 – release of 2.6 on 07/15/09) Development to support 2.7 release (07/09 – Present)

10. June 13 – 15, 2010 10 Automated Testing Introducing Selenium IDE: The workhorse of QA! Selenium IDE is a Firefox Add-On developed by OpenQA that allows for Agile Testing. Selenium allows for quick and easy automated test creation through a combination of recordable actions and HTML. We chose Selenium as a testing tool because of the necessity for reusable, scalable, and automatable test scripts that could be executed in a much shorter time span than manual testing.

11. June 13 – 15, 2010 11 Lessons Learned July 20091110th Sakai Conference - Boston, MA, U.S.A. Implement a well-defined internal process that complements the community’s development process Use available automated testing tools to keep up with the community’s development pace Communicate with the community Start early in the project Use community tools to share information (JIRA’s, Wiki, Weekly Calls, Sakai Devlist) The community is helpful, ask for guidance when needed Present at Sakai conference Consider partnering with an educational institute Provide access to the commercial components of your project

12. June 13 – 15, 2010 T UNING Z Optimizing Sakai on System Z

13. June 13 – 15, 2010 13 Grinder Open-Source Java based load testing framework Can simulate hundreds of unique users on a web application Reports statistics for HTTP method calls to Grinder console

14. June 13 – 15, 2010 14 Tuning Environment

15. June 13 – 15, 2010 15 Tuning Results We found the optimal environment for Sakai using WAS/DB2 on zLinux to be: 2 virtual CPUs defined in Linux 2 GB of memory defined in Linux Two swap partitions 1.Swap-1 (97.644 MB) 2.Swap-2 (781.156 MB) WebSphere Servlet cache enabled WebSphere Heap Size set to 256 MB - 1280 MB Using these parameters, performance was found to increase by 185% for 25 users from the original configuration. A graph comparing the two configurations is shown below.
