Hi everyone,
I am looking a configuration document for Message Broker under HACMP/IC91 support pack?
I think IC91 is not support for MB7 so is there any alternative or updates available to configure MB-HA failover solution?
Is it possible to create broker using MB7 - Multi-instance concept and then use IC91 script in HACMP configuration!
Has anyone configure the HA solution for MB7 in AIX environment? Please sugest any doucment or reference guide available!
Thanks,
Sonlika. |

You don't appear to be looking very hard.
You do NOT want to MIX Multi-Instancing with HA.
You SHOULD use one OR the other. NOT both. |

| We are using HA, so I just modified the hamqsicreatebroker script to remove references to DB2 items and anything else not needed in WMB 7. |

That's workable, but not supported. The link I made shows the supported scripts and methods. |

Follow the link I posted.
Use the scripts there.
Don't use IC91.

May I repeat what my most worthy associate pointed out - this is not a supported method for v7. As you correctly said yourself IC91 (in any form) isn't supported for v7.
That's not to say you can't get it to work or that you'll have immediate problems. You just need to understand and accept that if you do have problems, you'll be on your own.
Use the documented method for v7 unless you have a really compelling reason for sticking with the IC91 scripts. If you do decide that, please post your compelling reason (zpat, talking to you here as well - what led you down that path? What decided you? What's better about IC91? Throw some opinion here!  )

| Simple, we have a mixture of 6.0, 6.1 and 7 brokers on the same HA cluster and wanted to keep everything as consistent as possible. |

Fair enough.

It wasn't ever supported for ANY version of the Broker. Neither was MC91 supported for ANY version of MQ.
Yet MC91 + IC91 is still the only way to get a true H.A. Broker that can deal with pre-MQ 7.0.1.3 MQ connections.
And I may be speaking out of place, because I have not actually tried it, but even if all your MQ connections are 7.0.1.3 and newer, a multi instance Broker is still not as resilient as an "ol'-fashioned" H.A. Broker from the posts I have read. For example, killing all our Broker processes on a Multi Instance Broker doesn't initiate a switch to the alternate node, unlike traditional H.A.
MQ Client Auto Reconnect does not work for even the newest MQ Clients if they are base Java.

What do you mean by pre & post 7.0.1.3 connections?
If you mean MQ client auto-reconnect. This feature only works under certain circumstances. So it's been of limited use to us so far. |

The Multi Instance QMs (and the ability of other QMs to list multiple connames in a channel) and Client reconnect logic was introduced in MQ 7.0.1.0.
You can't download anything for MQ 7 earlier than 7.0.1.3 from Passport Advantage now.
