Questions and Answers

Week 3 (1/21/03 through 1/24/03)

I prematurely logged out of my account at SEASnet and I cannot stop my servlet container. What should I do?

Students who log out prematurely with their Apache Tomcat servlet container and cannot get back to end the process can do the following:

· Log in to the account

· Use the ‘ps –e | grep <user name>”

· Identify the ID of the other session(s) that was logged out prematurely

· Use the “kill <id>” command

· If that doesn’t stop the process, use the “kill -9 <id>” command

This should end the processes on the sessions that are logged out prematurely.

Week 2 (1/13/03 through 1/17/03)

I am assigned to different machines than my project partner. What should I do?

There would be no need to access the database of your project partner. Each student should either work on their own copy of the database, or be working together next to his/her partner. Working on the same database concurrently will lead to many problems, mainly communication between partners (if one person changed something and the other person didn’t know). If students are working on the project separately from their partner, each person should just work on their own script on his/her own, and then compare notes, or demonstrate it to the other person on one database. Remember, each pair of partner should only submit one copy of the project result.

Week 1 (1/6/03 through 1/10/03)

I’d really want to enroll in the class! How can I get a PTE number?

Students request PTE numbers should mail the TA at jthsiao@cs.ucla.edu by Wednesday midnight. Please include your name, SID, and the most convincing reason(s) of why you should get a PTE number. If you are a graduating senior or graduating graduate student, please also include the quarter that you are graduating (i.e., Winter 2003 or Spring 2003). Unfortunately, space in the class is very limited, thus we have to give priority to those that are the most in need of the class.

Is there a copy of DB2 I can download for my own personal use?

Yes. Students can download a copy of DB2 Personal Developer's Edition (DB2 UDB PE for Windows) to use DB2 on their own computers. However, copies of DB2 on a student’s own computer will not be supported by the instructor or the TA. Also, it is the student’s responsibility to make sure that the scripts that the students produce on their own copy of DB2 also work with the SEASnet version of DB2 when submitting graded material.
