Defining multiple threads for serial and parallel listeners

By default, HCL Commerce configuration provides two inbound listeners: one serial listener and one parallel listener. To use multiple inbound queues, you must define multiple inbound listeners for IBM MQ.To add another listener:

Procedure

Increase the number of threads for serial listeners:

Create a backup copy of the instance_name.xml file in case your changes cause errors.

Open the instance_name.xml file in a text editor and locate the snippet that defines a default inbound listener:


<Inbound> 
     <InboundSerialConnector 
       TimeToReconnect="600" 
       default="true" 
       enabled="true" id="1" name="Listener for IBM MQ (JMS Inbound) - Serial"> 
       
     </InboundSerialConnector>

Add a definition:


<InboundSerialConnector 
       TimeToReconnect="600" 
       default="true" 
       enabled="true" id="3" name="Listener for IBM MQ (JMS Inbound) - Serial - Custom"> 
       <JNDI 
         JndiName="eis/JCAJMS" display="false"/> 
       <ConnectionSpec 
         ClassName="com.ibm.commerce.messaging.adapters.jcajms.JCAJMSConnectionSpec" default="true"> 
         <EditableProperty 
           Admin="factory" 
           display="false" 
           editable="Yes" 
           name="setConnectionFactory" value="JMSQueueConnectionFactory"/> 
         <EditableProperty 
           Admin="inQueue" 
           display="false" 
           editable="Yes" 
           name="setInboundQueue" value="CustomJMSSerialInboundQueue"/> 
         <EditableProperty 
           Admin="errorQueue" 
           display="false" 
           editable="Yes" 
           name="setErrorQueue" value="JMSErrorQueue"/> 
         <EditableProperty 
           Admin="outQueue" 
           display="false" 
           editable="Yes" 
           name="setOutboundQueue" value="JMSOutboundQueue"/> 
       </ConnectionSpec> 
       <InteractionSpec 
         ClassName="com.ibm.commerce.messaging.adapters.jcajms.JCAJMSInteractionSpec" default="true"> 
         <EditableProperty 
           Admin="timeOut" 
           display="false" 
           editable="Yes" 
           name="setTimeOut" value="4"/> 
         <EditableProperty 
           Admin="mode" 
           display="false" 
           editable="Yes" 
           name="setMode" value="2"/> 
       </InteractionSpec> 
     </InboundSerialConnector>

Note:

Ensure that you substitute the correct JMS object names for the connection factories and queue destinations.
Ensure that you set the ID to a unique number.
