clarification of server.xml settings for AJP 1.3 Thread Limit
Greetings All
Happy New Year 2008!!
Question 01
on jboss side server.xml file, we wish to increase the maximum THREAD count
for the AJP 1.3 connector port 8009; (Default is 200)
Which parameter is used to do this ?
Question 02
Recently we have made our jboss servers j2ee compliant, earlier it was not.
Earlier we used the Apache front end to render all static pages such as
image files, php files etc...
Now we cannot do that, AS FAR AS WE KNOW, as j2ee does not allow it. So we
render everything from the jboss servers.
This has taxed our jboss servers and Apache is basically idle only doing
mod_jk load balancing while un-mounting all jpeg, gif, etc... files.
Is there a way we can have J2EE and have ONLY Apache render these static
pages ?
Thanks in Advance
Reg

Thanks David,
yes we experimented with JKumount in apache config, and it works fine.
the issue was we had a lot of paths to be set, but were able to get away
with the * character.
may be the issue of sending all that static page traffic over the AJP13
(mod_jk) AKA load-balancer was the imminent small packet size of the
protocol. also although we suspected the thread limitation was a issue, we
did not come across seeing a large number of threads opening at the same
time. does this make sense ?
ajp is meant to server small java scripts and jsp pages ?
thanks all for your help.
regards
mohan

Mohan,
You can use apache to serve all the static objects without the requests
going anywhere near jboss / tomcat.
Have a *careful* look at the JkMount command and look carefully at your
url-patterns that your application uses.

Where in the J2EE specs did you find that restriction?

Thank you very much.
We will try this, and inquire further if we run into complications.
On Question Once;
To increase maximum thread limit for AJP 1.3 on jboss's server.xml
Is it MaxThreads or MaxProcessors please ?
Thanks and Regards

If you can describe in terms of URL prefixes and/or suffixes, which URLs
belong to static content, you can do that by deploying a copy of the
static content on the web server and using corresponding URL patterns in
JkMount and JkUnMount.
