Hi guys,
Please excuse this post of mine, I have no time to search through the forum and I was asked to report to management in 2-3 hours time.
Basically the question is how to skew load between 2 cluster qmgrs.
I have sent the following to IBM MQ support. Please anyone advise too.
| Quote: |
| We have a MQ cluster. 2 full repository qmgrs are on z/OS, 4 partial repository qmgrs are on AIX. Messages will come from AIX to some cluster queue in z/OS qmgrs. We want to skew the load between the 2 full repository qmgrs on z/OS, which parameters can we change in the definition of the cluster queue in the 2 qmgrs on z/OS? What kind of skewness can we achieve by doing this? Can the skewness be controlled, say I want 60% of messages coming to the cluster queue go to qmgr 1 on z/OS and the other 40% to qmgr 2 on z/OS? |
Thanks! |

ensure that application queue exists on both the queue managers as a cluster queue....

yes you can

Gaya3, when time is pressing please try and be a bit more specific...

it depends, what type of load balancing the person requires, he/she should know the basics first then it will be good to dig in to the matter rather than pointing to the Solution.
from his question itself i can make out he is a new comer to MQ Field.

| CLWLWGHT channel attribute will allow the kind of distribution required rather than the CLWLPRTY queue attribute that the last link points to - but they are closely enough related that I guess you will have seen that. |

Sometimes the answer is needed (time dependency) and then the individual can then reflect on the how and why - we've all been in the situation of having the alligators snapping at our heels.
