## Connection Pooling

The Application Server pools JMS connections automatically.

To dynamically modify connection pool properties using the Administration Console, go to either the Connection Factories page (see Creating JMS Resources: Destinations and Connection Factories) or the Connector Connection Pools page (see Deploying and Configuring a Stand-Alone Connector Module).

To use the command line, use the `asadmin create-connector-connection-pool` command to manage the pool (see Deploying and Configuring a Stand-Alone Connector Module.

The `addresslist-behavior` JMS service attribute is set to `random` by default. This means that each `ManagedConnection` (physical connection) created from the `ManagedConnectionFactory` selects its primary broker in a random way from the `AddressList`.

When a JMS connection pool is created, there is one `ManagedConnectionFactory` instance associated with it. If you configure the `AddressList` as a `ManagedConnectionFactory` property, the `AddressList` configuration in the `ManagedConnectionFactory` takes precedence over the one defined in the Application Server.
