Terms

  • DB = database. As in FMPro DB.

Note

  • Please send corrections or changes suggested regarding this page to Oliver at <ChemIT>. Especially if this page can instead refer to A&S IT's directions, as the service provider. Or to instructional staff documentation, as the service user. Thank you!

Support and maintenance expectations

...

Roles and responsibilities: Chemistry Instruction, ChemIT, and A&S IT

...

All requests for service from from Instructional staff are to go to Chemstry Chemistry IT <ChemIT> if they have been vetted with Pat Hine.

  • Please distinguish between a request to fix something broken ("It worked yesterday!"), or something new needed or wanted (consultation/ design/ implementation).
  • In an emergency (time-sensitive situation), in addition to contacting ChemIT, Pat Hine may contact A&S IT support staff (Dani or Tu) directly, too.

Instruction staff who make structural changes to any of their DBs must inform A&S staff (Dani or Tu) as an FYI. Making changes may break things or processes.

  • Instructional staff are encouraged to involve A&S IT staff (Dani or Tu) if Instructional staff before making structural changes to their DBs.
  • Debugging a problem is easier if changes to the source DB is known up-front by those helping with the debugging.
  • Backups and restores may not work correctly if structural changes are made.
  • There are many, many moving parts to this complex and interdependent system!
    • One example: Uploads to the ChemGrades web site may not work correctly or otherwise need to be tested if structural changes are made.

A&S IT's services and role

  • A&S IT provides the FMPro server hosting services.
    • This includes performing and confirming back-ups and restore procedures.
    • Special focus is on addressing any infrastructure problem at their end.
  • A&S IT staff can do Consulting/ Design/ Creation work on a case-by-case basis
    • This will usually require Frank's approval, with negotiated timelines.

Procedures and processes

Semester-start procedures and processes.

...

In the fall, Pat Hine's first pull is no sooner than... (example: 8/29/13 (Thur)). Later for lecture-only courses.

  • Initially populating the DB with PeopleSoft data via a PeopleSoft import.This is a one-time event each semester for each course. (The wide range of courses are done at different times, depending on each course.)
    • Do imports in productions course DBs.
      • Can zero out or revert to prior DB if mistake made. If major problem, Pat can also contact Dani or Tu to revert to prior DB during normal business hours.
  • At the beginning of the semester (add/ drop period), Pat Hine will periodically grab copies of the back-ups so she can created statistics re: rate of enrollment changes.

Semester-end procedures and processes.

...

  • Pat Hine pulls the final data from the backups.
    • NOTE: If an edit is done, must wait until that edit shows up in a backup (~ half a work day) and then that backup becomes the "final data" for that course.
  • Pat Hine zeroes out each of the ChemGrades DBs before the start of their next use.
    • Pat Hine does this within FMPro, when she needs it done (varies by course).
  • Cut off TA's access to FMPro.
    • Pat Hine does this within FMPro, when she needs it done (varies by course?).
  • Some courses must not show the grade of the final exam, per faculty member's requirement.
    • In those cases, Pat Hine will simply not "push" her final data to the web (varies by course).
      • For these courses, grade changes for a student done after the last push (right before final exam grades entered into FMPro, ideally) will thus not show up on the web.
        • These are edge/ rare cases and Pat Hine will inform the student of this fact if a student asks.

DB revert procedure. Initiating request and subsequent restoration from back-up.

...

Pat Hine has access to last 7 calendar days of backups, 2 times per day. So, 14 backup files per course at steady-state, whether changes were made or not.

...

  • Zero out course data on the A&S FMPro server.
  • Import data from the correct course backup file.
    • Latest version would be from ~half a work day before.
  • If Pat Hine needs backup data older than what she has access to herself (> 7 days, so rare), she must contact A&S IT (Dani or Tu) for them to get via back-ups of the SQL server data (or from EZ-Backup).
    • Note that A&S IT's EZ-Backup would itself only have the 3 prior versions. If course DB was changed each day, that's just three backups. If course DB rarely changed, then that can be a long time.

Outstanding actions to consider

Make appropriate changes to source FMPro data

  • Change all TA access to be by NetID (and FMPro p/w), instead of their name.
    • This keeps the access process the same as it was, but:
      • Enables the correct access restrictions via the web application.
      • Facilitates transition to true NetID-based access, as a future project.

Enable Pat's view of DB data from home.

The need for this has been reduced since many folks can self-serve, and PatH herself has view-only web access.

  • Although the web version may be OK for view-only of some data, it's obviously not as flexible for searching. And there is no way for PatH to make changes through the web version.
  • On occasions when PatH needs full access, we will enable Remote Desktop on PatH's main work computer. This way she can do everything she can do when she's at work.
    • She can and does access her computer from off-campus via VPN.

As an alternative, if she knows she'll need it ahead of time, PatH can take a backup copy of any course on a FMPro computer for stand-alone access. This works as long as PatH doesn't make changes on the stand-alone DB that she later expects to see on the production, server-based DB, of course!

Rejected idea, for future reference: With FMPro installed on dept. laptop, access AS's FMPro server off-campus and do the work that way.

Ensure security of FERPA data in Grades DB.

See Michael Hint's emails with Tu and Frank for more on this. Some thoughts, initially:

  • FERPA-like data so ChemIT would appreciate understanding the ACL (see for subnet?) and firewall configurations.
    • ChemIT thinks there shouldn't be any off-campus access except via VPN. Thus take off of public net and put into 10-space. But there may be other factors to consider.
  • Access to the FMPro DB is controlled by NetID (AD groups). Once in, who else has access to Grades DB FMPro DB itself?
    • Answer: Only accessible to authorized FMPro users or groups.
      • If a user isn't authorized for a DB, they dont' even get to see that the DB is available.
      • If a user enters the fully qualified name to the DB they can't see (because they aren't authorized within the DB), the DB still wont' open.
  • Ideal: Make all access via NetID/ NetID p/w, not via FMPro DB's own controls.
    • Control NetID membership via Active Directory groups.
      • Start with Grad TA access, via theTA room kiosks? Also start with faculty access?
      • Once process confirmed, establish procedure for enabling and disabling NetID access to Grades FMPro DB by grads and faculty
        • Can take ChemIT staff less than a minute to do this, and is effective immediately.
  • Confirm FMPro server access is correct: Functional and secure.
    • Confirm that only permitted staff can access Grades (and other CCB) DBs.
    • Confirm Becky can see what she needs to see.
      • Add a read-only account for Becky.
      • Becky will still be able to exports her data, but no longer using PatH'/ the Admin account.
    • Confirm TAs can see/ edit what they need to edit for the TA room's computers.
