Thanks T. Rob,
Nice idea! For my purpose, it may make more sense to put messages to another queue and
forward unknown ones to the command queue whose permissions must be really-really
restricted. We will think of it more, but we may end up with just using command server
-- it looks like nobody knows what it does to really create a queue etc..
Sincerely,
Pavel

Pavel,
One technique would be to write a wrapper for the command server. The wrapper uses
and extends the PCF formats and monitors the command queue. Any commands that it
knows about are handled by the wrapper. Any commands it does not know about are
passed to the command server. The wrapper can provide extended services (display and
manipulate OAM settings for example) and can also extend the security model. The only
tricky part is to edit the amqpcsea binary to make it look at some queue *other than*
the command queue.

Hello Michael,
Thanks for the answer. The answer to your questions is "both and more". More is that
we have some controlling/monitoring process on Unix and Windows that uses server-side
MQI and if we were able to do what command server does based on PCFs, we wouldn't
require this yet another process (yes, having it has security implications and also
potentially affects resources and complexity and increases the number of moving parts).
I feel that using runmqsc is not better (rather, worse), than using command server for
our purpose. So I just wanted to know whether or not there is an API that command
server (and, for this purpose, runmqsc) use to do their job that our process could use
or it is all platform-specific and undocumented. We really want bare bones or the
lowest level available for the MQ administration software.
Thank you,
Pavel

Pavel,
the only 'process' that can create queues, etc... WITHOUT command server
running is: runmqsc
If you look at the runmqsc.exe for example on Windows, you'll notice it is a
very small
program... The API that runmqsc uses into QMgr is very obscure and IBM
internal as I have
understood.
Now the important question... why do you not want to run the command server
and find something
to replace it. Is it educational or are you driven by potential security
exposures?

Thanks Tim,
We (Monique and myself are working together) are actually not after that
book. The book says how to do things when the command server is running; our
purpose is to understand if it is possible to write monitoring application
that does not require command server to, for example, create a queue, but
does it "instead of the command server". Is my suspicion correct that the
command server works on a low level and there is no cross-platform API it
uses to create a queue?
Thank you in advance,
Pavel

The manual you are after is "Programmable Command Formats and Administration
Interface" and its not easy. Any given single thing is relatively easy to do
but there are an awful lot of things you can do.

Hi,
I would like to know the API or mechanisms used by Command Server to
perform administrative tasks(eg create a queue) on the Queue Manager.
Is there any API that I could use to write my own command server for
Unix and / or Windows?
