Vista Update

Here's the latest news in a set of emails from John at BB to David:

The problems today are related to the build-up of files that haven't been removed in garbage collection (GC). I (David) am going to paste in John's (from BB) explanations below:

When you e-mailed Lee about having trouble uploading files I went in and added some indexes to the CMS tables and reported how much GC had to do to you. That's why it was slow. Once we reboot the system tonight GC will start cleaning up those 16 million content items in the CMS tables.

Right now GC has been cleaning up old student records and sections but not content items. I think this is why uploads have been so slow.


I just finished adding the tracking job indexes to fix the tracking data.

That job will run Monday Wednesday and Friday starting at 5a.m. Please let me know if you see anymore Unknown Users after tomorrow evening.

I also added the indexes for Garbage Collection. That job will run Tuesday Thursday Saturday and Sunday starting at 10p.m. and ending 8 hours later.

Finally I added indexes to the CMS tables. Uploads are now blazingly fast from my connection here at home and my neighbors DSL connection over wireless-b.


John asked me earlier if we would ask instructors to delete their section backups once they have downloaded them. We need to put into our training and instructions to faculty about not leaving heavy files, like backups, in the MyFile area. As Vista administrators, we also need to delete backups now would be a good time so that the database is free of unnecessary data. The GC hasnt worked, but after tonight we should be on the road to cleaning this up.

Thanks for your patience, and lets see how the system works for the next couple of days.

I will get LisaMarie to write up directions for deleting back-ups you may have made, then if you would take care of that we could begin the semester reasonably clean.

Many thanks!
