HI ,
I am trying to create a Clustering environment on 2 Test servers following the IBM info center-> Advanced Tasks-> Task 1 to Task 3 , I created 2 test qmgrs and made them as Full repos and now added 2 more Qmgrs to both the Full repos one in each, but now when i tried to put the messages using ./amqsput i am able to put the messages to the clusterQ from all the qmgrs but not able to get in qmgr that is hosting the clusterq as in info center it is said that the messages will e routed alternatively. 
now i did like the same as above but not able to get the messages in Toronto( i can put and get messages only in that qmgr, the msgs put in Toronto are not appearing in Newyork where as i can get the msgs for Newyork, london and Paris in newyork but not routed alternativey Between Toronto and Newyork) please let me know what i need to do now.
Thanks in Advance,
Mitra |

You will need to be much more specific as to what you have done; and exactly where (which qmgr) you did the amqsput.
First, did you follow the WMQ Clusters manual on setting up a cluster?
Did you include the CLUSTER() attribute on all instances of the clustered queue? Post the QLocal definition here.

I followed the same way they said in IBM Info center
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.amq1ac.doc/lq10500_.htm
but now as u said i am able to put messages from London, Paris , Newyork and can get the messages only in Newyork as QCluster is physically defined there, But my question is when i Added the Qmgr Toronto and defined the same QCluster in that as it was stated in Info Center document i am not able to Get the messages alternatively in Newyork and Toronto. I am able to get the messages in Nweyork and in Toronto i can get the messages that are put in that Torornto Qmgr only but not the messages that are kept by London and Paris.
Hope you understand better this time what my problem is . |

No sir i followed the same procedure except for message affinities steps in the steps for adding Toronto as these Qmgrs are just the Test Qmgrs so i think no need of message affinities. |

Apparently you didn't because if you had you would have read somewhere that you can only get messages that have been delivered to a qlocal to the qmgr you are connected to. MQ Clustering does not change that.

You can not troubleshoot.
You need to change your understanding.
Messages are only held on qlocals.
Clustering does not change that.
Applications can only issue MQGet against a qlocal on the MQCONN they have.
Clustering does not change that.
You say messages are held on LONDON and PARIS, but you do not explain how you mean.
Please explain. |

HI
I didn't get what you are saying.
i will try to explain the scenario more clearly.
As you see in the diagram , I too created the Clustering environment the same way. I read in Info center doc that when the Qcluster is created in Full repo Qmgr the instance of it will be available in other Cluster Qmgr(F.R and partial repo). upto there everything is fine.
The thing is i am able to put the messages from London, Paris and Newyork to Invent Q which is Hosted by Newyork and i too knew that i can get the messages where the Invent Q is Physically located.
But when i added Toronto to host the InventQ i read that the messages will be routed alternatively between Newyork and Toronto but its not happening,
2. The messages kept in Toronto are not able to get in Newyork? My question is we have InventQ in both the Qmgrs(Newyork and Toronto) so why i am not able to get the messages kept by Tonoto in Newyork and Viceversa.
I hope i am clear now. |

a mq cluster will distribute messages when they are put. not when you try to get them. once a message has reached its target queue, you can only get it from there.

WMQ clusters is/are an advanced topic. A number of us are professional consultants; and we would entertain an engagement to come to your site for training and problem-determination on clustering and other topics.
