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 element can be configured to use an Executor element:
…
…
<Executor name=”HibernateExec”
className=”org.apache.catalina.core.StandardThreadExecutor”
namePrefix=”HibernateAPP”
maxThreads=”75”
minSpareThreads=”20”
maxIdleTime=”10000”/>
<Connector executor=”HibernateExec”/>
…
…
NOTE: All Executor elements that are configured in NSJSP must implement the Java interface
org.apache.catalina.Executor . NSJSP provides a standard implementation of this interface
in the class org.apache.catalina.core.StandardThreadExecutor .
Configuring TS/MP Specific Parameters
This section describes the following TS/MP specific configuration parameters:
1. Numstatic – Determines the number of static NSJSP processes.
2. Maxservers - Determines the total number of NSJSP processes.
3. TANDEM_RECEIVE_DEPTH – Determines the handling capacity of each instance of NSJSP.
4. Maxlinks – Determines the maximum number of TS/MP links. The number of simultaneous
messages that can be delivered to an instance of NSJSP is determined by Maxlinks . NSJSP
reads these many number of messages from the $RECEIVE file simultaneously.
5. Number of Connector threads.
The configurations for Numstatic , Maxservers , TANDEM_RECEIVE_DEPTH , and Maxlinks
can be set in the Server directive in the <iTP WebServer deployment
directory>/conf/servlet.config file on OSS. Before configuring NSJSP, it is important
that you determine the maximum load that each instance of NSJSP is expected to handle.
The way these configuration directives drive the NSJSP environment depends on whether
the
SessionBasedLoadBalancing feature is turned ON or OFF .
• NSJSP Configured with SessionBasedLoadBalancing Turned OFF
• NSJSP Configured with SessionBasedLoadBalancing Turned ON
NSJSP Configured with SessionBasedLoadBalancing Turned OFF
• The value of Numstatic must be [(Average Load)/(Max load one instance of
NSJSP can handle)] .
• Maxservers must be [(Peak Load)/(Max load one instance of NSJSP can
handle)] .
• The value of Maxlinks must be set to the peak load that one instance of NSJSP is expected
to handle.
