Hi Guys
1st Post... should explain alot about my question!
... I dont even know how to put this into words...
here goes:
App puts message on QM2 ToQueue2 with is a remote definition of Queue1
ToQueue1 is a remote definition of ToQueue0 which is local.
ToQueue0 process message and replies on fromQueue9 which is an alias of fromQueue0 which is a remote of fromQueue1...
and this works until this point
... which is local... ummm, there was something confusing about this...
Where does a message go if the queue isnt local? ... onto the transmission queue? Can a transmission queue be 2 ways? And how would MQ distinguish which is going and which is coming? And what does the inhibited put or get do?
If a queue is inhibited from messages being put, then how do messages get on the xmit queue? And if get messages is inhibited, whats the point of putting a message on there?
I apologise for the mess.
But any helpfull feedback will be very much appreciated!

I do hope this is a theoretic example not an actual design! You need to spend some time with the Intercommunication manual, which explains a lot of valuable concepts.
Moving on:

Yes

See above

What it sounds like

They don't

Because you don't want them got yet
Spend some time with the manual, and ask about the training budget at your site.
Happy Reading!

Haha... unfortunatley this is the actual setup.
I have most of it documented on paper, I got here when the damage was done!
We do need this setup due to firewall requirements... Im assuming.
The bouce box is used to handle messages from all over and send them where they need to go... its messy and Im struggling.
Where is this manual of which you speak? Haha.. Hopefully there is an online manual... to which you could hopefully direct me to. I got handed MQ with no understandin of what is going. I went on a very basic coarse, which hasnt helped me understand the mess thats going on here!
And thanks alot for the very fast reply!
Very helpfull! |

Look under the "Documentation" button at the top of this page for "Intercommunication" that is an online version.
Happy reading and good luck! |

Ask Mr Google about MQIPT (Internet Pass Through). If you need that lot to get round firewall restrictions, there's something very odd about your firewall restrictions.

What you're describing here is a hub and spoke architecture, which is nothing to do with firewalls per se, quite common, and not as complex as you seem to have drawn it. At least not normally.....

You'll find all the MQ documentation at :
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp
a URL you'll find peppered through this forum if you look. Which I recommend you do at some point, as there are some valuable nuggets in here.
Word of advice - get your feet wet with a simpler test setup (on your local PC or similar) before tackling the larger setup. MQExplorer open in one window, manual in another window kind of thing.
Then ask for a better training course!

One thing that I dont have... is time!
And where I work, security is of the utmost importance, and bypassing the firewall is something Id rather not try. If the net admin had to find out, my glutes would be toast!
Ill jump through the information centre and try get a better understanding.
Thanks alot guys! |

You need to read up in the intercommunications manual.
Here are a few topics that will help you understand:
-- multihops Or sending the message from qmgrA to qmgrC passing through qmgrB
-- qmgr alias
-- Default xmitq. Very important in an hub and spoke design...
Enjoy

I do not understand how you can not have time to do your job correctly.

It will take you less time to understand it and then work on it, than it will to work on it then try to fix it!

IPT is not about bypassing the firewall - it's about getting MQ properly configured to use the firewall, like all the other applications that pass data through it. I also remain unconvinced that the hub & spoke you descibe has anything to do with firewalls; more likely it's a business mechanism.

This is a road leading to disaster. MQ is too complex for you to "jump" through the documentation and administer, unless you have the kind of luck better applied to lottery tickets. Especially in a set up as interconnected as the one you describe.

The issue was an alias had a base queue name of the sender queue.
Thanks for the advice though guys!
Chances are Ill be back... after I've read through the MQ Manual
Later |
