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™.
