Re: [xmlblaster-devel] reconfiguring topics

what is best practice, to send the administrative topic config message
from publishing applications or to configure the queues separately?


This depends, if the publisher is primitive (for example a simple C based
publisher in a wind speed device) if could be adviceable to create the
topics as an adminitrative task.
There is a 'StartupTasks' native scripting plugin which you can activate for such things, see
http://www.xmlblaster.org/xmlBlaster/doc/requirements/admin.startupTasks.html
Note this is beta code and not a lot tested yet.

If your publisher is a clever backend server it may well create the topics
itself on the fly.

About administrative topic creation please see
http://www.xmlblaster.org/xmlBlaster/doc/requirements/interface.publish.html
and search for <administrative/>

Hi, During development I sometimes need to change the properties on
existing topics - I would like to keep the same name. I always seem to
get warnings such as 

[Jun 9, 2005 8:25:24 PM ERROR Thread-5
TopicHandler-/node/xmlBlaster_127_0_0_2_3412/topic/ross] Sorry we are in
state 'UNREFERENCED', reconfiguring TopicHandler is not yet supported,
we ignore the request

Sometimes the state is 'ALIVE' etc.

What is the proper procedure for reconfiguring a queue?

Hi Ross,

sorry, as the ERROR says, reconfiguration is limited to certain topic states.
The only save way is to erase and create the topic new
or use a second topic having the other features you need.

Which properties you want to change?
Adding the feature is probably not a big issue but needs
to be analyzed for each case,

Marcel
