warp connector and number of connecionst
Hi!
What does maxProcessors attribute in warp connector mean ? I thought it
is the total number of connections between apache and the engine the
connector was defined in, but I see there is many times more established
tcp connections between my apache and tomcat then defined in
maxProcessors. Maybe it is the number of connections for every
application ?

That very well may be the case -- I find keeping up with what's going
on with the connectors one of the most confusing and least documented
(there's a relationship there :-) parts of Tomcat. Also, I haven't
really looked at the 4.1.X stuff yet, I've been working with 4.0.X.

Milt,
You're absolutely right. WARP isn't replaced or deprecated. The wires in
my head get crossed a bit now and then :) I apologize for causing any
confusion.
I was under the impression that in 4.1.x, Coyote could handle the both the
Java side of AJP13/14, and HTTP 1.1, so it can be used to run Tomcat
standalone or behind a webserver.

Michael Locasto

I don't think this is correct. For one thing, I believe they are for
different things -- WARP is a connector for integrating Tomcat with a
web server (e.g. Apache), while Coyote is for running Tomcat
standalone. WARP may be replacing AJP (i.e. mod_jk), and Coyote may
be replacing the older HTTPConnector, but I don't think anything's
being deprecated. And actually, "replacing" probably isn't correct
either, they just may represent different alternatives -- for example,
many currently seem to prefer mod_jk over mod_webapp (the Apache
module that handles the Apache side of WARP), and it's not clear
if/when that will change.

I'm assuming you're using some 4.0.x version, I think warp has been
deprecated and replaced by Coyote in 4.1.
This document isn't of much use...
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/warp.html
but you can probably find out the answer in the source
org.apache.catalina.connector.warp.WarpConnector
I believe that maxProcessors represents the number of threads that will be
created to handle request/response pairs. However, each thread can probably
handle a number of open connections.
In the following config entry, perhaps acceptCount is the number of
connections each "processor" can handle.
<Connector className="org.apache.catalina.connector.warp.WarpConnector"
port="8008" minProcessors="5" maxProcessors="75"
enableLookups="true" appBase="webapps"
acceptCount="10" debug="0"/>
The source would be your best bet.
Regards,
Michael
