Of course, Peter, I saw your solution.
And I agree with Victor is an elegant one ... but does not fit our case, so I have to change it too much ... or just cant (dont know hot to) change it to fit our case.
first difference : you say "I'm assuming the replying app is connected to a QM outside the cluster".
In fact, our responding app starts using triggering in QMAS q mgr (see previous schema), which participates in the cluster.
second problem : the message coming into the cluster does not have the replytoqmgr field blank, so the responding applications sends to a specific qmgr
And I dont know if the qmgr alias mechanism can "erase" this field so clustering comes into play again ...
Trying to rethink our envir to "live" with the response message coming to s fixed qmgr ... Maybe it is not so bad, jejeje
I appreciate your help, realy. Sebastian. |

You should try it to see that it does

Thanks, mr Saper - I understand what you say, but we have no "external" qmgr ...
Our sending APP connects to cluster using MQ client.
In fact, the 3.000 shops (able to open 15.000 simultaneous connections)
connect into the cluster using CCDT (s), so they dont know at what qmgr they are connected at a given moment ...
Best luck. Sebastian. |

Well, here are the results ... to Peter's indication ...
Message I sent is goes to
destination Q = [QL.DADES.TRIG]
where it is "responded" using triggering ...
and values
replyToQ = QL.DELPHI.GRAW.OUT
replyToQmgr = VITOR_WUZ_HERE <<<<<<<<<<<
Without any change ... we have an error, as expected :
| Quote: |
>>> Put1() a msg. hCon [0x1400006].
Q
[QL.DELPHI.GRAW.OUT ],
qmgr
[VITOR_WUZ_HERE ].
+-+ MQPUT1() CC/RC [0x02/0x0827] {MQRC 2087}. |
Now Peter's imporvement comes : at "responder" qmgr, we define
| Quote: |
| define qremote(VITOR_WUZ_HERE) RNAME(' ') RQMNAME(' ') XMITQ(' ') replace |
And the result is ...
a) if one cluster queue defined ... (qmgr = CLSPATAN)
| Quote: |
display ql(QL.DELPHI.GRAW.OUT) curdepth | runmqsc CLSPATAN
QUEUE(QL.DELPHI.GRAW.OUT) TYPE(QLOCAL)
CURDEPTH(94) |
b) if more cluster queues are defined ... they are also used
| Quote: |
display ql(QL.DELPHI.GRAW.OUT) curdepth | runmqsc QMAS
QUEUE(QL.DELPHI.GRAW.OUT) TYPE(QLOCAL)
CURDEPTH(11) |
I have to say : BIG THANKS to you all, Vitor, Morag and Peter, and mr Saper ...
pd.- you have the right to know there is an extract of what we've talked and done in my "blog" at
>>> http://usuaris.tinet.cat/sag/mq_cluster.htm
... if you search for "Peter" ... or "SAGCLUSTER"
Any improvements are always welcome, as well as contructive criticism ... |

Thanks for your patience, Vitor.
I think we already had a very similar discussion some time ago, but I cant find it using "search" ...
You also said the sender always wants to receive the reply.
But MQ allows you to specify where to send it.
It is NOT mandatory to receoive it at the same qmgr where you send the request.
And I agree with you 98% ... jejeje
Just want to be able to specify where to send the Reply (or response)... and also want to be able to send it to a cluster q ...
Again, I appreciated your patience. |

I simply pointed out the traditional pattern of request / reply has the reply going to the requestor. It's certainly not mandatory to do that, and other patterns of message movement (like "workflow") are possible.

And now you can. Life is good and the joy flows like rain.

Yes, I have seen that phrase quite few times ... jejeje ...
q.p.quo :
"you never go so far as when you dont know where you are going",
...
said mr Cromwell (excuse my traduction, but cant find the original phrase)
I have found this :
“no one rises so high as he who knows not whither he is going” |
