 Arnold K. Pizer - WeBWorK installation problems  6/27/2001; 3:27:46 PM (reads: 864, responses: 1) We're getting closer to getting WeBWorK to work. When we try to login with a valid user from our classlist database we get the following message: "Error: Key database error Can't tie /Net/lunen/cis/www/oncampus/academics/mcs/webwork/system/courses/mcs121a/DATA/.auth/mcs121a_password_DB: Interrupted system call" Any suggestions?

The "Can't tie" message means the database can not be read. Look at e.g. the last few steps in item 24 of http://webwork.math.rochester.edu/tarfiles/linuxredhat.html (building the demoCourse) assuming you have followed the steps up to that point. import_classlist-database.pl demoCourse demoCourse.lstNow enter (using [Tab] completion):setProfPermissions.pl demoCourse apizerYou should see a listing of permissions with apizer having permission 10. Another possibility is that the webserver is not in the group and so can not read the database or you haven't restarted the webserver after adding it to the group (see item 23 in http://webwork.math.rochester.edu/tarfiles/linuxredhat.html ). In general http://webwork.math.rochester.edu/tarfiles/linuxredhat.html gives very detailed instructions which are very useful even for non linux systems. Let me know if the above doesn't do the trick. I'll post your email and my response to http://webhost.math.rochester.edu/webworkdocs/discuss/ Arnie <| Post or View Comments |>
