I am connecting to Oracle 9i using JDBC in my JSP/Servlets web pages with Tomcat 6.0.20 container. I am closing all my connections in Finally blocks. Everything works great during the day with JDBC and Oracle where only 2 people are using the web site with about 300 small records in the Oracle database.
But after a Web crawler runs through our web server at 3 AM the next morning a v$session check shows several lines of JDBC Thin Client inactive status marked at 3 AM. Any way to find exactly what sql statement or program that could be causing the JDBC Thin Client to show up?
