If there is a connection in the pool which is connected to a Queue Manager that matches the queue manager name specified by the application and CCDT entry, it will be used. To prevent connections from using too much resource, you can limit the total number of connections that an MQSimpleConnectionManager object can accept and also you can limit the size of the connection pool.

If the maximum number of connection has already been reached and a new connection is now required, destroy enough of the longest running unused connections to allow a new connection to be made and make that connection.

The default value is ignored, but if the application supplies a channel name and a CCDT, an MQException will be thrown with reason code If a suitable definition is matched, then the MQ Java client will try to create a connection to the queue manager using the information supplied in the definition.

The reason for including the asterisk is so that the connection name defined for the selected client channel definition may actually define a server and port number that will result in a connection to a queue manager with a different name.

Java exits are specified by just the class name.

Alternatively, applications can construct an MQSimpleConnectionManager object to override the default connection pools behavior. Connection name The host name or IP address of the server machine and the port to connect to.

Even if the channel name that is set matches a channel name in a definition in the CCDT an exception will be thrown, because it must be clear how a connection is created and which channel was used to do so. From this point on, the connection pool manager takes over and either reuses an existing connection, makes a new connection, or fails.

This is provided so that it is possible to create a group of logically name back end servers that can cover workload and availability.
