Troubleshooting VISITview Training Sessions
Updated 6/1/2009
For instructors:
- The server is probably down if:
- theBig Red Pointer does not appear initially
- A message: Cannot contact server appears on the screen
- you click on the screen and the BRP does not move to that position
- you are running the Status Window, and the status does not update every 10 seconds (minimum)
- If the server is or goes down:
- Have everyone (including yourself) stop the current session by closing the Client window.
- Run one of the alternate batch files to connect to a different server.
- A site may have the wrong lesson file or be using the wrong batch file if:
- Everyone else has the BRP and can see your page changes and/or annotations, yet the site can verify their Internet connection is OK (for example, they can access remote web sites using Netscape or IE).
- If a site is using the wrong lesson or batch file:
- if they have it on disk, have them just run the batch file from that directory
- if they do not have the correct files, they need to try to download and install them and re-join the lesson.
- otherwise, they will have to reschedule.
- A site may have a firewall problem or a networking problem if:
- they do not see the Big Red Pointer, or get a "cannot contact server" error message, but everyone else is fine
- everyone else can see your page changes and/or annotations.
- If a site has a firewall or networking problem:
- they should contact their local network administrator
- they should run the visitlocal.bat file and turn their own pages
For students:
- You may be using the wrong lesson file (sometimes lessons do get updated)
or be using the wrong batch file to start your lesson, if:
- initially the Big Red Pointer appears on the screen, but none of the slides show up
- you click your mouse button at some location on the screen and the Big Red Pointer moves
- none of the annotations show up on your screen
- If you have the wrong lesson file:
- if you have a copy of the correct one on disk, just switch to it and run the batch file
- if you do not have a copy on disk, you can try to download it, install it and rejoin the lesson
- otherwise, you'll probably need to reschedule for a different day & time
- If you are using the wrong batch file:
- close the window and run the correct batch file.
- You are not connected to the server if:
- If the Big Red Pointer does not show up on the screen initially
- you get an error message about Cannot contact server
- If you are not initially connected to the server:
- verify that you are using the correct batch file
- if you are, you may have a local network or firewall problem -- contact your network administrator
- you may be able to continue the lesson using the visitlocal.bat file -- but you will not be able to see any of the instructor's annotations.
- You may have lost connection to the server during the lesson, if:
- the instructor is changing pages, drawing on the screen or doing other actions that you are no longer seeing, assume you have lost connection to the server.
- you suddenly get an error message on the screen
- your system seems to have "locked up"
- If you loose connection to the server:
- stop your current session by closing the window
- close all other active applications (you may have run out of memory)
- rerun the batch file (like visit.bat)
- if that fails to re-connect you to the session, let the instructor know. You may have to run "visitlocal.bat" and "turn your own pages", if you cannot get reconnected.
