>From doing research, Tomcat 4.x and on, which implement AJP13, no longer has a connection thread pool for the AJP13 connector. It apparently does have one for the HTTP connector though. The reason why we need a thread pool, is because our main web servers can spawn anywhere up to 500 connections multiplied by 5 apache web servers, and they connect to only two Tomcat servers. From experience, and from research, I understand that the correlation of threads from Apache to Tomcat is 1 to 1, which means approximately 2000 threads are attempted to be open on the two Tomcat servers (1000 each), and so the Tomcat servers thread max reaches and becomes unresponsive. I understand that I can raise my maxprocessor limitation on the AJP13 connector to 2000, however, I feel that is very bad resource management because realistically I know that the particular applications that we've ported to Tomcat only get a *maximum* of 5 concurrent connections (info obtained from when running on Weblogic). I'm assuming Weblogic's connector is better able to handle it's thread resources, because it has a thread pool implemented on its 'connector. I found info that leads me to believe that Tomcat 3.x, using AJP12 had some built in thread pool functions. Here's a URL that explains: http://www.hp.com/products1/unix/webservers/apache/techtips/tomcat.html " Using a thread pool in Tomcat is a simple move; all you need to do is to use a PoolTcpConnector in your <Connector> configuration. For example the following server.xml fragment defines ajpv12, pooled Connector: Pooled ajpv12 connector <!-- A pooled AJPV12 Connector for out-of-process operation --> <Connector className="org.apache.tomcat.service.PoolTcpConnector"> <Parameter name="handler" value="org.apache.tomcat.service.connector.Ajp12ConnectionHandler"/> <Parameter name="port" value="8007"/> </Connector> " Is anyone aware if in some undocumented way that this function still resides on AJP13? I'm unable to locate any information relating to such. Otherwise, is anyone aware of a solution or workaround to my problem? TIA
