You can create additional JMS hosts in the following ways:
Use the Administration Console. Open the Java Message Service component under the relevant configuration, select the JMS Hosts component, and then click New. For more information, see To create a JMS host in Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Administration Guide.
Use the asadmin create-jms-host command. For details, see create-jms-host(1).
The JMS Hosts list is updated whenever a JMS host configuration changes.
