When a connection is ended, all resources that were acquired by the activation group through the connection and all resources that were used to create and maintain the connection are no longer allocated.
For example, when the activation group executes a RELEASE statement, any open cursors will be closed when the connection is ended during the next commit operation.
A connection can also be ended as a result of a communications failure in which case the activation group is placed in the unconnected state. All connections of an activation group are ended when the activation group ends.
