Added files:
/loncom/misc refresh_courseids_db.pl
Log:
- Bug 5967.
- Contents of nohist_courseids.db (excluding lastaccess) rebuilt from permanent data in
course environment.db files.
- Will determine course owner and/or creation date for old courses created before these items
were in use, and update course's environment.db file accordingly.
