Configuring server.xml
- Locate the HTTP Connector element in the server.xml file located under the
<TOMCAT_HOME>/conf
folder. The default connector port is 9080 for virtualizecli and 8080 for a WAR deployed in Tomcat. - Add/update the
acceptorThreadCount, enableLookups,and maxThreads
attributes as shown in the following:Example:
Code Block <Connector URIEncoding="UTF-8" acceptorThreadCount="2" connectionTimeout="20000" enableLookups="false" maxThreads="750" name="default" port="9080" protocol="HTTP/1.1" redirectPort="9443" server="Parasoft Server"/>
This tells Tomcat to keep a processing thread pool of 750 threads. It also sets the acceptor thread count to 2 and disables DNS lookups.
Locate the Valve element toward the bottom of the file.
Comment out the Valve element as shown in the following:
Example:Code Block <!--<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false" /> -->
