In the native codebase, as in the Java codebase, any queue can be specified as the admin reply-to queue. However, it is recommended that the default admin reply-to queue name, MQE_ADMIN_REPLY_QUEUE_NAME, is used to name a queue dedicated to the role of admin reply-to queue. This name corresponds to MQe.Admin_Reply_Queue_Name in the Java codebase.
In practice, the native client is more likely to be receiving than to be sending admin messages. In this case, the client needs a remote asynchronous queue definition of the admin reply-to queue on the server as well as a home server queue matching a store-and-forward queue on the server to enable the admin and admin reply messages to be transferred.
