Some MQ Cluster defaults are dangerous

The defaults for many cluster channels are not very good.  For example the values for
CLWLPRTY,  CLWLRANK and CLWLWGHT are all 0, meaning the lowest priority.

If you want to make one connection or queue a lower priority, you have to alter all the cluster receiver channels, and local queues, to have a value  – such as 5, let the definitions propagate round the network, and then change the one you wanted!

It may be worth doing this over an extended period, so you get good values, without disrupting your MQ environment.
