The Application Server pools JMS connections automatically.
To dynamically modify connection pool properties using the Admin 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.
The other addresslist-behavior alternative is priority, which specifies that the first broker in the AddressList is selected first. This first broker is the local colocated Message Queue broker. If this broker is unavailable, connection attempts are made to brokers in the order in which they are listed in 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.
