Subject Re: limit threads per servlet in Tomcat
Date Fri, 08 Dec 2000 16:18:13 GMT


Oh yes there is a way to set it. In the server.xml file. Like this

        <Connector className="org.apache.tomcat.service.PoolTcpConnector">
            <Parameter name="handler"
value="org.apache.tomcat.service.connector.Ajp12ConnectionHandler"/>
            <Parameter name="port" value="8007"/>
            <Parameter
                name="max_threads"
                value="3"/>
            <Parameter
                name="max_spare_threads"
                value="2"/>
            <Parameter
                name="min_spare_threads"
                value="1" />
        </Connector>

Just find the Connector entry corresponding to the one above and go for it. The
nodes that youll need are the 'thread' named nodes.

Yes, it'll hit your performance (esp OutOfmemory) if you don't allocate enough
for the possible threads so take care.

Hi

I wish to setup Tomcat to limit threads per servlet, say 20 threads to
execute in one servlet concurrently. the 21th request would cause the
Tomecat engine to generate a new servlet instance.

Is there a way to do it. any comment appriciated.

Also, what's the performance concerns. is that possible to create a pool of
servelts?

Thanks

Jay
