we need to set up high avalability for WMB7 in solaris platform using veritas
can some of you please provide the link on the proper documentation and recommendations to set up HA of WMB7 in solaris environment using veritas.
are any support packs released for WMB7 for HA? I haven't worked on HA before. Please share your views in this regard. |

Yes, you can and probably should still use MC91. It may say it is deprecated but you can still use it. Hope fully, they have updated the document with the Multi-Instance commands that replaced some of the HA* commands. I have not read it in a while. I have used it at WMQ V7 (although for AIX with Power HA).
If you have a 100% WMQ V7 environment, then you should do the Multi-Instance QMGR instead. That would include the MQ Clients... |

all mc91 features are incorporated in WMB7. so mc91 not required for HA setups in WMB7.
mc91 documentation can be followed for HA setup at WMB7.

if eric is using WMB 7 then the prerequsite for WMB 7 is WMQ7. so WMQ 7 100% already be there. 
I would say mutiinstnace should be used only when there is no MQ Cluster with HA queue managers.
There are some bugs reported in Multinstance setup with MQ Cluster !!! |

And what about all the other QMs and MQ Clients that are going to be talking with this WMQ7 / WMB7 set up?

Do you have some examples?
Eric, whether you go Multi Instance QM/Broker or not, make sure you find and read Support Pack MC91 + IC91. Unless all your incoming QM connections are MQ 7.0.1 or better, you will have to go the traditional H.A route described in these 2 Support Packs.
Here's a Webcast on Multi Instance Brokers:
http://www-01.ibm.com/support/docview.wss?uid=swg27017847
And an article on the same:

Thanks for the replies.
I followed your suggestion i went through those support pack documents and now i am some what better in understanding the HA setup.But i have some questions which i eagerly waiting for the help.
IBM says that mc91 functionality is made part of WMQ7 and MC91 is out of support. Now we are not planning to go with MQ7 and with Veritas instead of multiinstance feature provided in MQ7. Now As Mc91 is made part of wmq7, are their any articles that shows how to create RUntime components in WMQ7 with VCS with out using MC91 as MC91 is mainly providing scripts to create a runtime components hacrtmqm... |

Don't double post, especially to "grab our attention", as you so politely phrased it here. If you have urgent questions, raise a PMR.
We're volunteers, not a support desk with an SLA.

i apologize for that. i had a great respect for this forum and it wont be repeated.
At normal condition our setup should contain
Node A :BRK A (active) BRK B (Passive)
Node B :BRK B (Active) BRK A (Passive)
i am planning to create QM A in Node a and Link it in the Node B and create QMB in Node B and link it in Node A. So that both the nodes resources will be used effectively instead keeping them idle.
But In MC91 i came across this statement "If the HA cluster will contain multiple queue managers then, depending on your chosen cluster
configuration, two or more queue managers may need to run on the same node after a take over."
So how i need to proceed on achieving my required setup.  |

Just proceed normally. You have what is called an active / active configuration.
What the sentence above means is:
Depending on the HA clustering, at any moment of time you might have node 1 being down and QMA and QMB both running on node 2, or node 2 being down and QMA and QMB both running on node 1. Basically standard failover stuff between the nodes and just what you would expect.
Have fun

HI all
I am also working to setup the MB7 HA with veritas .Hence posting my question here
I am planning to make use of mc91 support pack for creation of the Qmanagers instead mq multi instance feature. And instead of IC91 support pack(as these features already incorporated in MB7) i am planning to create Multi instance broker with the Qmanager that are created using mc91 support pack.
Did any one implemented the same approach ? Am i thinking in a correct way? Can the qmanagers used using MC91 be usedwith the multi instance Brokers ? or the multi instance QM's are only to be used with multi instance Brokers?  please share your views and experiences |

if they have direct communication with Broker then it should be V7.

No i heard it in Webcast questionaire for Multiinstance Broker that there are problems reported in MQ Cluster for Mutiinstance qmgr.

High Level Steps for creating Multi Instance Broker :
1.Create a shared work path directory.
2.Create multi-instance queue manager.
3.Create a multi-instance broker
So Multi Instance Queue Manager required for creating multi instance broker. |

Hi Gurus,
I am going through all the MB7 high availability posts in the forum, These provide useful info, But none has concluded any thing on the proceedure that needs to be followed hence requesting again in this link.
Have any one setup HA with Veritas using Mc91 for MQ and Broker Multinstance option. will it work? I donot not have any test environment to play with the HA setup and check it working or not 
desperately waiting for yor views. Please suggest. |

MQ and Broker multi-instance are not really compatible with other HA technologies.
Broker multi-instance uses the MQ qmgr multi-instance to manage it's failover.
MQ multi-instance requires that the standby instance is active, although processing no work, on the standby hardware.
Traditional HA presumes that the standby machine is entirely passive.
In addition, under traditional HA, you only have *one* queue manager and *one* broker. In multi-instance you have... *more* than one (you know, multiple) queue managers, even if they are to some extent "the same".
So you could configure multi-instance on top of traditional HA, but then you'd essentially be failing the primary instance over onto the same hardware that's already running the secondary instance (which MQ doesn't like!).
But you'd also have to be very careful that the HA failover process of moving the file systems between two mount points didn't interfere with the file locks used for multi-instance failover.
That way leads to pain and suffering. Stop now. Pick one or the other. |

mqjeff:Thanks for the reply
i started my practice work by completely ignoring the multiinstance feature in MB MQ
I have gone through the mc91 and ic91 scripts and understood the proceedure that needed to be done for making broker and qmagers capable for failovering. I have created the component by implementing the steps hacrtmqm and hamsicreatebroker scripts perform. AS i am currently not having the VCS setup i have made a copy of file sytem where all the runtime data is stored and replicated it another server which has same level of mq and mb installions are done. In the second machine i followed the steps that are stated in halinkmqm and hamqsiaddbrokerinstace script . in the second machine the failover qm and the failover broker running successfuly  now i got some understanding of the HA setup.
BTW My environment is also having WTX integration server along MB7. Please suggest if any extra activities are needed to be done for WTX Integration server to get failover sucessfully. I believe not. please confirm |
