Configuring Connector Threads
The Connector is responsible for creating and maintaining the threads that are used for message
processing. A thread is allocated for each incoming message; therefore, the number of messages
that can be processed simultaneously can be controlled by limiting the number of threads the
NSJSP Connector can spawn.
NOTE: A single connector can service multiple instances of the container. The connector must
be configured such that it can spawn threads sufficient for all the container instances. In terms
of configuration, the
Host element in the server.xml configuration file represents a container
that is serviced by the connector.
The NSJSP Connector thread pool can be connected using the following ways:
• Configuring the Connector Element
• Configuring the Executor Element
Configuring the Connector Element
Configure the maxThreads attribute of the Connector element in the <NSJSP deployment
directory>/conf/server.xml file on OSS. The Connector element is the child of the
Service element.
For example: The following snippet shows the configuration in the <NSJSP deployment
directory>/conf/server.xml file on OSS, if you want to configure 75 simultaneous
connector threads.
…
…
<Connector protocol="HTTP/1.1"
connectionTimeout="0"
acceptCount="25"
maxThreads="75"/>
…
…
Configuring the Executor Element
You can configure the Executor element as child elements of the Service element in the
<NSJSP deployment directory>/conf/server.xml file on OSS. The following snippet
of the server.xml configuration file shows the configuration of the Executor element and
how a Connector can be configured to use an Executor.
…
…
<Executor name=”Axis2/JavaExec”
className=”org.apache.catalina.core.StandardThreadExecutor” namePrefix=”Axis2/JavaAPP” maxThreads=”75”
minSpareThreads=”20” maxIdleTime=”10000”/>
<Connector executor=”Axis2/JavaExec”/>
