Subject RE: JDBC Error
Date Fri, 28 Jun 2002 13:16:04 GMT

John,

My assumptions:

  - it would time out since I have ended my session with the Linux system
(no other users connected), I can leave it for 5-10 minutes with no problem

  - that when I start-up my browser from my NT system and the Servlet issues
JDBC connection it would then reconnect

Have I made a mistake in my assumptions? I have also been through the
progress logs and no indications there.  I have tried playing with some of
the timing but it has not made a difference.

Thanks
Roger

Just a guess, but could your database connection be timing out under linux?

Best Wishes

Subject: JDBC Error



I have an application which is running fine on WinNT but on Linux it fails
under the following condition:

    - the first time into the application - no problem
    - I close the web browser
    - it is left for about 15 to 20 minutes
    - I try to start the application again I get the error

I have debug set in Apache and Tomcat but they do not give me any clues.
Below I have my configuration and the top portion of the error log file.

I would appreciate any guidance/suggestions which would help me track this
down.

Thanks
Roger
