Hi guys,
I got a client concentrator setup with 001 and 002 having webspher and 003 and 004 having WF servers. 003 is a first QM in the cluster and has repository. all other QMs are in the same cluster.
When I bring down 004, all users can login without any problem. but when i bring down 003, users will get time out error and subsequent try will log them to 004. I am not sure why it work like that.
I am guessing the entries in the fmcrc
Configuration/xxx/MQClusterCommunicationAddress=xxxx003
Configuration/xxx/MQClusterPort=1414
on both the boxes will point them to 003 first.
also how the entries
Configuration/xxx/FMLServerChannelTable=/var/fmc/chltabs/MQWFCHL.TAB
Configuration/xxx/FMLClientChannelTable=/var/fmc/chltabs/MQWFCHL.TAB are used by WF and when.
Any thoughts will be appreciated!!!

Did you mean you brought down the QM on 004 ?
Also do you have only one cluster repository ?

Do you have the connect names for both the WF systems on your client concentrator machine?

Thanks Manoj. Yes I bring down QM and WF completly on each box to simulate failover. Also, you were right, I have only one cluster repository.
I suggested MQ guy to make 004 as backup respository. I am not sure, whether that is going to solve the problem
Rathan, I need some more info about connect name and where to give that.
Thanks for ur inputs

Clustering is not a failover solution.
to add connect names:
1) fmczutil
2) Select config ID
3) client settings menu
4) connect names
5 add.

Hi Rathan,
Two entries are there on there for two systems sys1 and sys2. But in program they call fmcgrp,fmcsys1. Will that causing any problem?
I don't think we cannot say check sys1 or sys2 while creating the session.
I am expecting, once the entries are added to connection names, WF/MQ should able to identify and logon to live one.
Let me know ur thoghts
Thanks,
-Mahesh |

In the program you should only use the Group name (FMCGRP)...
Do not pass the system name. Instead pass empty string ("").

you should only specify the Group Name (no System name) to login to be able to leave the loadbalancing to MQ.
