I am trying to create a cluster network on one system. This is a cluster gui demo available from IBM support pack. There are four servers SERVER1, SERVER2, SERVER3, SERVER4 as queue mangers and CLIENT1 as queue manager. They all have listeners running on same machine (tcp/ip) but on port numbers 1502, 1503, 1504, 1505, 1506. They have a shared que
DEMOQ (cluster queue) as given in example.

When I put message using following command

amqsput DEMOQ Server1

and access message using

amqsget DEMOQ Server4

why I do not get message? it is clustered que running on same machine.

I chekced all channels status - running. SERVER1 is repository. However in demo they have not defined any sender channel from SERVER1.

http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg24006438&loc=en_US&cs=utf-8&lang=en

graphical clustering demo. There is error in defining SERVER1 port 2102 instead of 1502.

I am running demo on windows machine

thx

Is your put successful? have you tried using capitals for the server names?

amqsput DEMOQ SERVER1

and access message using

amqsget DEMOQ SERVER4

Enjoy

Yes put is successful. A message put in DEMOQ cluster que on SERVER1 can be acessed from SERVER1. However it is not accessible from SERVER 2 or 3, 4 . DEMOQ is hosted on all qmanagers (SERVER1,2,..4 and client1) on same machine. It is cluster queue.

You can't GET from a queue that is not a QLOCAL to the queue manager you have connected to.

Clustering doesn't change this.

The only way for a message PUT to DEMOQ queue on SERVER1 to be GETTABLE from SERVER4 is if the workload balancing decided that SERVER4's copy of the DEMOQ queue was the place to put it.

If you are not using version 6, or have not taken additional steps, and you PUT to SERVER1 and SERVER1 has a copy of DEMOQ, then the message will only end up on SERVER1.

The Queue Manager Clusters manual is your next step. Good luck.
