Sakai Questions

QUESTIONS FROM THE IT TEAM OF ESSEX COUNTY COLLEGE

1) What are the reasons for selecting SAKAI as your favorite learning management system?

• Rice had a deployment of Web CT that had some traction 4 years ago.
• The  timing was right with the Sakai consortia, the purchase of Web CT by Blackboard and the desire for Rice to support an open source initiative. The catalyst for change was a proposed huge increase in licensing costs for Web CT.  Due to increased use, our license needed to be expanded to a campus wide license.
• Rice has close peer relationships with some of the Sakai founding institutions.

2) What is your SAKAI infrastructure?

3) Which database version did you choose to use for SAKAI Installation?

• Oracle 10g 

4) Which operating system version are you using for SAKAI?

• Red Hat Enterprise Linux 4

5) How frequently do you apply SAKAI patches?

• Version upgrades are performed during the summer break.  A few minor patches/upgrades are performed during the short winter break.  We have a weekly maintenance window in which any small patches that are needed and have been tested are applied to the system.  We use this maintenance window about once per month to install small patches.

6) Who provides you SAKAI maintenance and support?

• In-house

7) How do you resolve SAKAI issues?

8) What are the resources that you use for resolving SAKAI issues?

9) How is SAKAI integrated into Banner?

10) Did you develop the integration tool or acquired it from a third party?

11) What are the programming languages used to develop such an integration tool?

12) Can you share with us the integration tool?

13) Do you offer strictly online or hybrid courses?

• Most Rice classes are face-to-face. Sakai is used to distribute instructional resources more than it is as a formal teaching venue.
• Only a few courses are taught in what Sloan-C would define as a hybrid model.
• Most of our small catalog of on-line offerings are done through video connection or classroom capture with Sakai playing a supporting role. 

14) What are the SAKAI best practices that you adopt?

15) How frequently do you purge the SAKAI data for previous semesters?

• Currently, we do not purge. Sakai's current version does not offer a tool to do this conveniently.

HARDWARE AND INFRASTUCTURE QUESTONS

16) What are the server specifications? (manufacturer, hardware and software specs, VMWare)

• Sakai Servers:
  • Sunfire 4100
  • 3 Dual Core AMD Opteron(tm) Processor 275
  • 8 GB RAM
• Database Server:
  •  Sunfire 4150
  • 2 Dual core AMD Opteron Processor 2.8 GHz

17) What type of storage do you use for the servers?

• 1 TB Hitachi SAN

18) What type of backup system do you use?

• Data is backed up to a secondary storage area, which is then backed up to tape

19) Where are the servers hosted? (any cloud computing)
20) How do you load balance access to the system?

• We use a Netscaler 7000 with Sticky Sessions, Automatic load balancing and automatic failover.  This also allows us to remove one server at a time from use in order to apply any rolling patches if needed.

21) What is your Internet connectivity? (T1, DS3, DSL )
22) What is your client connectivity speed?
23) Any issues with client software when accessing the system? (eg. Internet Explorer 8, Firefox, toolbars)

OTHER ISSUES:

24) We know that some data from Banner tables such as: Roster, Course, Course Section, etc needs to be exported into Sakai in a CSV format. Does that data need to be parsed?

25) Which Sakai tables need to be populated from external data source?

26) Can you explain to us how you achieve mapping of fields from Banner to Sakai Course Management API
