[LON-CAPA-admin] Course Editor: Map not loaded error

[JaBari A Scott]

Good Morning Stuart:
I cannot recreate Sally's error this morning.  I have assumed the role of
Course Coordinator and have enrolled myself as an instructor and I simply
cannot recreate the error.  I have checked the folder for CHEM 303 as you
suggested and all appears normal there, as well.  Any guidance would be
greatly appreciated!

Thanks so much!

Sally,

> "Map not loaded: The file does not exist."

That error message originates in the loadmap() routine in
/home/httpd/lib/perl/LONCAPA/map.pm and will be displayed if no content is
retrieved from the sequence file for the particular folder.

Were you were seeing this error in a session on VCU's LON-CAPA library
server: loncapa2.vcu.edu or one of the four VCU access servers? Is this
problem in your CHEM 350 (Fall 2014) course or in your CHEM 303 (Fall
2014) course?  Which folder was the Course Editor attempting to edit?

The LON-CAPA version in use at VCU is 2.10.1.  In that LON-CAPA version
the last folder you displayed in the Course Editor is recorded, so that
when you next access the Course Editor, the editor will (by default)
display the last viewed folder.

Your system administrator should likely check on the filesystem on
loncapa2.vcu.edu to see whether the requested sequence file actually
exists, and if so, what is currently within the file.

e.g., in the directory:

/home/httpd/lonUsers/vcu/2/M/1/2M129584749da535dvcua2/userfiles/

for CHEM-350-2014Fall

or in:

/home/httpd/lonUsers/vcu/2/l/1/2l14814c993a45323vcua2/userfiles/

for CHEM-303-2014Fall

The top level folder is default.sequence, lower level folders will have
filenames like: default_<timestamp-like string of digits>.sequence where
<timestamp-like string of digits> is a string of digits (e.g.,
1409257997).

You can see what the "timestamp-like string of digits" is for a particular
folder, by viewing the Course Contents page, opening all folders and
moving your mouse pointer over the folder icon for the particular folder.
The corresponding link (shown in the browser's status bar) will contain a
"jump=" attribute pointing at the URL of the sequence file (from which you
can extract the filename:
default_<string of digits>.sequence).
