ANGEL Update
Audience: ELC and ITC
What’s New: SBCTC and ANGEL teams met yesterday and put plans in place to make the following technical updates. The intent of these updates is to (a) restore “What’s New” functionality and (b) clean-up old / bad data to reduce threats that may affect ANGEL performance.
“What’s New” Nugget
- Disabled Jan 14th per ANGEL recommendation. Performance improved.
- There have been considerable requests from College users to restore this feature, so SBCTC and ANGEL will re-enable “What’s New” on Monday, January 25 at 9:00am, PST.
- To reduce potential impact of re-enabling “What’s New” SBCTC and ANGEL staff will: a) Disable all WAOL ID courses prior to W10 (~8100 sections) b) Reset the nugget view mode to hide disabled courses – for all users c) Globally remove all announcements over 8000 characters in courses prior to W10. See item below.
- On Monday, January 25th SBCTC, ANGEL and Colleges will monitor performance and disable “What’s New” again if problems are reported.
- ANGEL’s longer-term recommendation is to build a custom version of “What’s New” that touches less data. SBCTC staff continues to work with ANGEL on this. Full discussions of options will happen in the WAOL Advisory Group meetings (every other Monday in Elluminate: next meeting Jan 25: 11am).
Bad Email Cleanup
- Remove email addresses identified as not active in order to reduce the number of exceptions log.
- Likely no performance improvement due to the relatively small number on active accounts (~300).
- No expected impact on current users.
Large Announcement Cleanup
- Large announcements are a known cause of performance problems in ANGEL.
- Some identified large announcements have already been removed by instructors.
- SBCTC staff will globally delete large announcements (>8000 chars) for regular courses prior to Winter ’10.
- Will notify ELC and post on blog before deletion.
Student Activity Log Cleanup
- ANGEL recommends removing this data for inactive courses.
- SBCTC staff will remove entries prior to Aug 1, 2009 – millions of records.
- Cleanup will be scheduled during a quieter system time (weekend), using best SQL practices for removing large number of rows.
- No expected impact on current users.
Please Help: Detailed information provided by you is extremely helpful. ANGEL Domain Admins – please continue to update the open ANGEL ticket (# 596-8312283). That information is seen immediately and is used by SBCTC, ANGEL and College teams.
Thank you.
