[LON-CAPA-users] error on new course

[Mueller, James A.]

Stuart,
Cloning worked the second time.  Thanks. The only problem is renaming the failed course

Within loncapa, I don’t see a way to rename the course.  As Domain Coordinator, I can change the course code, so I did that, but I am not sure how to change the course title or disable auto enrollment without entering that course.  I can list all users who have roles, and it looks like it is only me as course coordinator, so I revoked that.  I think with the course code changed to an invalid value, there will be will be no way for auto-enrollment to add any students.  I was never able to enter the course, so there is no work there to lose.

What might have gone wrong here, and is there any way to fix it?


It sounds as though copying from the course being cloned to the new course failed for the top-level map (i.e., the default.sequence file) in the old course.

The courseID of the new course tells me that your session was hosted on pittmath1, i.e., the Pitt Mathematics department's access server when you created the new course, and not Physics-Astronomy's library server (pittphyast1).

That means that there would have been a number of calls to retrieve sequence files (including default.sequence) from the library server, followed by copying, then modification (to replace instances of the old courseID with the new in any src attributes in the default.sequence file), and lastly notification to the homeserver for the new course (i.e., the library server) to copy the modified sequence files from the access server to the library server for permanent storage.

The routines in lonclonecourse.pm which are used for cloning do not currently return any information about success or failure of the various operations which occur when cloning a course, so you'd need to look in /home/httpd/perl/logs/lonnet.log on the access server, and/or /home/httpd/perl/logs/lond.log on the library server for information about failed replication.  However, since lonnet.log is rotated, the information in the lonnet.log file may no longer be around, if you created the new course more than a few days ago.

What to do?

Depending on how much work you have done in the new course, since cloning, you could just create another course, (again with cloning), but this time with a web session hosted on the library server.  You could then rename the current "2171_24834 PHYS 0081 Space & Time, Light & Matter" course, disable auto-enrollment, and expire all roles.

Or you could attempt to repair the 6E101732148bb57dcpittmath1 course by using  command line access (as user www) to copy the default.sequence file from /home/httpd/lonUsers/pitt/$1/$2/$3/$clonedcourse/userfiles/default.sequence to /home/httpd/lonUsers/pitt/6/E/1/6E101732148bb57dcpittmath1/userfiles/default.sequence, and then use a text editor to replace any instances of $clonedcourse with 6E101732148bb57dcpittmath1 (where $clonedcourse is the courseID of the course that was cloned, and $1, $2, $3 are the first three characters in that courseID).

Of course it may be that other sequence files, besides default.sequence, were also not copied/modified from the old course to the new course, so you might need to do the same for them.

The other day, I cloned a course from last fall for use in the  coming term.  I thought it worked, but now when I try to access that  course as course coordinator, I get the following error message:

The following problems occurred:

Map not loaded: The file  /home/httpd/html/userfiles/pitt/6E101732148bb57dcpittmath1/default.sequence  does not exist.

What might have gone wrong here, and is there any way to fix it?
