Hi
Is there any option to implement clustering with WMB/WBI? Like MQSeries has the CLustering support. Do we have similar support for Broker?
My understanding is that Broker does not support clusteriong (like MQ does) and we have to use third-party tools like Veritas. Any thoughts?
Thanks |

MQ clustering is *NOT* a failover solution.
A typical highly available Broker implementation looks like this:
Two machines under HA control (HACMP, Veritas, ServiceGuard, MSCS, etc.), in active-passive mode with a standby node (so four machines total).
On each machine, the following resources in a failover group:
Broker
MQ
(broker database)
Each Queue Manager for the broker is in an MQ cluster. This provides load-balancing of broker flows from the rest of the MQ network.
The configuration of a typical HA Broker environment on z/OS is completely different, though.

Thanks for your reply.
So HACMP is also like Veritas? Only that its provided by IBM. Does my statement make sense?
I am familiar with veritas and not others and hence this basic question. Thanks for your understanding. |

Yes on all counts. Google for the specific features / similarities / differences.

I have an environment consisting of two servers, each with an active broker, that is load balanced through MQ clustering. Given this configuration, what benefit could be obtained by implementing HACMP?
From what I've read it seems like HACMP would only be beneficial if an active / passive approach was taken where you would want the passive broker to come up immediately if the active instance went down. Is this a true statement? |

What if one broker goes down, and you are in the middle of peak processing, and one broker can't handle the load?
