** Using WeBWorK **

We then tried to move existing courses over to the new server. We moved files to the appropriate directories, ran course_webwork_setup and set up the needed symbolic links. We did not run the import classlist script assuming this was not necessary because the database files already existed, and we wanted to preserve them. We were unable to login receiving the following error:

Error: Key database error Can't tie /var/www/webwork/system/courses/M144Pollina/DATA/.auth/M144Pollina_password_DB: No such file or directory

However, these files do exist and seem to have the correct ownership and permissions.

Any help would be appreciated.

First note that the GDBM binaries are OS dependent. If your old server was running Solaris, then you can not just transfer the binary databases to a new server running Linux.

In this case if you want to transfer existing databases, use the shell scripts:
export_classlist-database.pl
export_password-database.pl
export_permission-database.pl
export_webwork-database.pl

Then transfer the resulting ascii files and then run:
import_classlist-database.pl
import_password-database.pl
import_permission-database.pl
import_webwork-database.pl

Don't transfer the keys database. It will be recreated.

Hope this was your problem.
