I am running 3 servers; Apache, Tomcat (5.5.16, java version "1.5.0_06", Informix JDBC-1.3.00.JC3) and Informix (7.31.UD2). After the app has been idle for several hours tomcat cannot access the database. Netstat shows not connections to the database and tcpdump shows no traffic at all going the database when queries are made to the app (which would cause the database to be consulted) At first it seemed that the overnight backup of the database was causing this problem but restarting tomcat after the backup only fixes this problem for a few more hours. I wrote a loop to wget url's that cause the database to be consulted every 60 sec but after several hours this problem happens again. Tomcat seems to be fine, I can load the management page and restart the app. Only restarting tomcat fixes this problem, reloading the app does not fix the problem.. Nothing is being logged during and right before this problem.
Does anyone have suggestions to further debug this problem ? -- James H. Edwards Network Systems Administrator Judicial Information Division [EMAIL PROTECTED]
