Making CCB's very important ChemGrades DB more robust, and enabling necessary increased functionality, especially for teaching faculty and students. Ensuring its long-term support and operation. Representing customer is Pat Hine's (PatH).

Updates
8/16/13
- Cname of grades.chem.cornell.edu from as-chm-vsrv-09.ad.cornell.edu to sf-as-data-001.serverfarm.cornell.edu has been submitted and will take effect at the 11am DNS update.
To do's
See the following section for context related to these to-do's.
Enable Pat's "push" capabilities so her DB info can be seen on the web
- Tu will work with Roger.
- Tu needs IP addresses. Roger can do the installs.
- And Roger may have better alternatives. :-)
Test PatH's restore procedure.
- Do ~end of Sept? (No later, please!)
Enable PatH's remote access
- ChemIT must do this.
- Oliver must do or assign.
Enable ChemIT staff's access to CCB FMPro DBs.
- Do via AD group. Enable only "Admin" accounts, not ChemIT staff's user accounts. (Right, Roger?)
- Tu to work with Roger.
Ensure FMPro access by TAs and a few staff
- Ensure the "one account" for one course for many TAs is cleaned up. (Legacy data.)
- Dani and PatH
- Ensure works from systems: TA room, DanL, CynthiaK, and Sam's.
- ChemIT staff:MichaelH.
Decisions, processes, and procedures
Establish procedure for PatH to update web-hosted data. "Push the button".
As of 8/16/13, function doesn't exist for PatH.
- Requires ODBC connection. Not possible at FMPro server; must be set up at FMPro client's computer.
- Do for PatH's computer. As backup, do on Sam's computer.
- Current plan: For each computer, set ODBC up as system's Admin (vs. user) so ODBC accessible/ configured for any computer account.
Establish semester-start procedures and processes. Includes:
This fall, PatH's first pull is no sooner than 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. (Courses done at different times, depending on course.)
- Do imports in productions course DBs.
- Can zero out if mistake made. If major problem, contact Dani or Tu to revert to prior DB.
- Do imports in productions course DBs.
- At the beginning of the semester (add/ drop period), PatH will periodically grab copies of the back-ups so she can created statistics re: rate of enrollment changes.
Establish semester-end procedures and processes. Includes:
- PatH 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.
- PatH zeroed out each of the ChemGrades DBs before the start of their next use.
- PatH does this within FMPro, when she needs it done (varies by course).
- Cut off TA's access to FMPro.
- PatH 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, PatH 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 PatH will inform the student of this fact.
- 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.
- In those cases, PatH will simply not "push" her final data to the web (varies by course).
Establish DB revert procedure. Initiating request and subsequent restoration from back-up.
PatH 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.
- Backups are made for each course.
- Backups are made around noon (morning data changes) and in the evening (afternoon data changes).
- Each backup's name contains a date and time-stamp.
- Files are located on Instruction's file share (R:\ drive).
PatH can do any restore herself using FMPro, ensuring "low friction" access to the backup files (nobody to contact, not hoops to jump through).
- Zero out course data on the A&S FMPro server.
- Importing data from the correct course backup file.
- Latest version would be from ~half a work day before.
- If PatH needs backup data older than what she has access to herself (> 7 days, so rare), she must contact Dani or Tu for them to get via back-ups of the SQL server data (or from EZ-Backup).
- Note that A&S'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.
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 accasions 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 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.
- Answer: Only accessible to authorized FMPro users or groups.
- 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.
- Control NetID membership via Active Directory groups.
- Confirm FMPro server and admin groups support required staff access rights.
- Currently it authorized CCB staff to see all PatH sees.
- Confirm Becky can see what she needs to see.
- Exports data using PatH's account.
- Confirm TAs can see/ edit what they need to edit.
Clarify support and maintenance expectations
- Clarify to what degree A&S staff (Dani and Tu) are available and willing to perform support.
- Hosting vs. Design/ Creation vs. Support
- Distinguish between something breaking (worked yesterday!) and new need (consultation/ design/ implementation).
Map out transition steps remaining
- Change direction of cname, <grades.chem.cornell.edu> from old to new instance.
- ChemIT needs a date.
- Doing this means other systems (2 computers in TA room; Becky's computer) automatically cut-over. :-)
- Shut off access to old ChemIT-run instance (Win7 VM). "Legacy Grades".
- ChemIT needs a date.
- When add access via AD groups?
