Optimizing Tomcat with Http11NioProtocol?

Hi, we are still using 5.5.12 in production and our users are facing increasing delays with their requests (like way too long by now already). While we are not entirely sure about what's causing this (database vs Java application), we suppose it comes from the Java application (the database

my suggestion would be to make sure if the delay is coming from the connector or somewhere else, you could use some monitoring tools jmeter [http://jakarta.apache.org/jmeter/], moskito [http://moskito.anotheria.net/] or just write your own filter which logs the number of active session, the

Hints on upgrading from 6.0.14 to 6.0.18 on production server

Hi I have a 6.0.14 running with Apr 1.1.10 and I seem to be seeing instances of CVE-2007-6286: Tomcat duplicate request processing vulnerability (64-Bit Server VM (build 1.6.0_03-b05, mixed mode) (Centos 5.0 - Linux 2.6.18-8.el5 x86_64 ) The obvious thing to do is to upgrade from 6.0.14

Re: Hints on upgrading from 6.0.14 to 6.0.18 on production server

If I'm not mistaken, the APR has caused the bug, and 6.0.16 contains a new version of the APR. Since this usually comes as a source, you'll have to re-compile the APR. Cheers Gregor -- just because your paranoid, doesn't mean they're not after you... gpgp-fp:

Re: Optimizing Tomcat with Http11NioProtocol?

Try using jconsole.exe (it is part of the Sun JDK) to review memory and thread usage of your JVM. That should help you narrow down where the issue is. One key thing to look at with Jconsole is the heap memory used figure. You are setting your -Xmx, but how much of it are you actually using?

Re: Optimizing Tomcat with Http11NioProtocol?

Glad to be of help. First, I don't think that APR has anything to do with thread management. I think the two things it does really well is to serve up static content and provide native SSL processing. Tomcat 6 and/or Java 6 may help with though (I would assume so, but I don't know for sure).
