In order to influence the cluster workload algorithm, I would like to test if I can set a cluster queue parameter "PUT(ENABLED)" to "put(disabled)" from a mb flow.
In fact, I dont like put(disabled) because you cant disable all instances of a cluster queue. I think changing the CLWLPRTY is better, as you never get to a situation with no queues available.
So I can change my question to :
how can I change CLWLPRTY from a MB flow ?
Thanks for any URLS or sugestions.
Sebastian. |

Well, you could easily construct a BLOB message in ESQL that happened to contain a PCF Change Queue command.
For some value of 'easily'. |

Jeff - good idea, but I still need some sample. I am quite green (new) on MB.
Now I am reading \ms0b\com.ibm.mq.pcf\examples\ ...
Cheers ! Sebastian. |

Take a look at the AMQSCLM program that now ships with MQ.

| This sample uses the built-in WebSphere® MQ cluster workload balancing features to direct messages to instances of queues that have consuming applications attached. This automatic direction prevents the build-up of messages on an instance of a cluster queue to which no consuming application is attached. |

Thanks both, guys - you both point me to the same article, even on diferent mq versions, jejeje - mr Peter -> 7.1, mr Saper -> 7.5
Will read in a minute.
But in our situation (see bellow), the consumer is always there - it is a MB flow.
And I think resending messages is not the way to go - you can get into a loop !
More on Monday ! Have to play tennis this evening .... jejeje

I see you also got my other "half" of the question.
Thanks a lot for your help.
Would like to pay you a beer if you come to Barcelona, as Michael did ( )
