Administration messages

Once created, queue managers are configured by the sending of administration messages to the target queue manager administration queue. A queue manager that does not have an administration queue cannot be administered. The intent behind using administration messages is that both local and remote administration is performed in an identical manner.

An administration message is created and sent to the administration queue of the queue manager to be administered. You can apply queue-based security attributes to control access. An administration message includes details of the request, indicates whether or not a response is required, and contains the address identifying the target queue manager and queue. Therefore, MQe has the following styles of administration message:
  • Commands that indicate an administration action that does not require a reply
  • Requests that require a reply
  • Reply messages constructed from a copy of the original message
The sender can add additional fields for use by the receiver. The administration queue itself acts upon the message. Administration messages can inquire on, create, delete, or update objects. For a subset of the objects they can perform additional functions, such as stop and start. See Configuring MQe objects for more detailed information on administration messages.

Administration messages can also be generated indirectly through the MQe_Explorer, a management tool that provides a graphical user interface for system administration. MQe_Explorer is not included with MQe but is available for free download as a SupportPac™.
