## Creating Physical Destinations

Produced messages are delivered for routing and subsequent delivery to consumers using physical destinations in the JMS provider. A physical destination is identified and encapsulated by an administered object (a `Topic` or `Queue` destination resource) that an application component uses to specify the destination of messages it is producing and the source of messages it is consuming.

If a message-driven bean is deployed and the physical destination it listens to doesn’t exist, the Application Server automatically creates the physical destination and sets the value of the property `maxNumActiveConsumers` to `-1` (see Load-Balanced Message Inflow). However, it is good practice to create the physical destination beforehand.

You can create a JMS physical destination in the following ways:

- Use the Administration Console. Open the Resources component, open the JMS Resources component, then select Physical Destinations. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Administration Guide.

- Use the `asadmin create-jmsdest` command. This command acts on the default JMS host of its target. For details, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Reference Manual.

To create a destination resource, see Creating JMS Resources: Destinations and Connection Factories.
