Re: Monitoring production tomcat
Hello Maybe Tcat from mulesoft is something to look into regards Milko Adam Lipscombe adam.lipscombe@g mail.com To users@tomcat.apache.org 03-02-2011 10:57 cc Subject Please respond to Monitoring production tomcat Tomcat Users List us...@tomcat.apa che.org Folks We have a several production servers, each of which runs 1 instance of tomcat. Within each instance of tomcat there are approximately 10 virtual websites. Each virtual website runs a copy of our web app. Therefore each server hosts @ 10 instances of our web app On a couple of the servers we are having problems with tomcat running out of memory and sometimes dropping the JDBC link to the MYSQL database etc. We usually restart tomcat, which of course cures the issues. However doing do affects every virtual site and therefore is not ideal from our customer's perspective. We have been looking at this problem for some time, however it is very difficult to determine what is causing these problems. Very likely something in out webapp. What would help is some kind of management or monitoring facility that allows us to see which virtual site is getting into trouble. Ideally it should give enough information to help us track down what is causing the issue. Memory usage per site, thread view etc. Can anyone recommend anything that can do this? Commercial or free?

tomcat shows intermittent error page and good page for jsp
Hello We have the following situation on tomcat 6.0.29 First we deploy a good jsp and tomcat shows it correctly. Then we introduce an intentional error in the jsp to test the error page we want to display. What happens is the application shows the error page, but when we refresh the page it shows the good jsp. And does this a couple of times after which it shows a couple of times the error page again and so on. In the logfiles I can see that tomcat is not able to compile the defective jsp as expected. What is going on here? greetz, Milko Please consider the environment before printing this email.

Re: tomcat shows intermittent error page and good page for jsp
But if it is caching why does it first show the error page as it should? And then the previous version of the jsp again. Could it be that the original jsp is still in memory and gets replaced only when the new version is compiled correctly?

problem with dynamic code in jsp
Hello We are running tomcat 6.0.29 with tridion broker We have a jsp with code inside that dynamically fetches data from a database. When we put a changed jsp in place it gets compiled and shows the fetched data from the database. When we change the data in the database and refresh the page, the changed data is not displayed. Only a republish of the jsp or a restart of tomcat will display the changed data from the database. Could this be a caching problem with tomcat? if so; how do we prevent this caching from happening? if not, what could be the source of the problem then? greetz, Milko Please consider the environment before printing this email.

Re: [OT] re : spam

Somehow it seems to originate from (or maybe simply mention) the tomcat users list as a reply-to. I have also seen at least one message like that in the list itself. Anything that should/can be done about this ? Does it mean that someone harvested the list of subscribers to the list, or worse ? Or is it just me ?

Re: Why an email list, and not a forum?
I agree. A forum would be more practical. It is much easier reading all postings on a topic. I find myself clearing my tomcat users list inbox every morning, while on forums I visit I check out the new or updated topics. The forums these days let you subscribe to topics or complete forums and send you a notification when a new topic gets started or updated. regards, Milko Brian bbprefix-m...@ya hoo.com To users@tomcat.apache.org 24-09-2010 02:19 cc Subject Please respond to Why an email list, and not a forum?
