Hi,
Is there any case study/configuration guide available for an MQ HA Solution with RedHat Cluster services.
Regards. |

We are taking a look also at using either Veritas CS or RedHat Cluster Services for how Websphere Message broker HA solution.
Anyone know where to find information on the Red Hat Clustering Services for MQ/Broker??
thx |

No such animal exists.

| No such animal exists - do you mean that no documentation exists or that MQ running uner RHCS is not a supported configuration ? |

When we looked to do this in 2008 I could not find any documentation. Whether some doc exists today or not I don't know. Back then RHEL did not have an agent for MQ or WMB.
Technically, IBM only supports MSCS on Windows as a hardware clustering solution for MQ.
But they will support you on officially supported hardware and O/S if the problem can be replicated outside of the hardware clustering solution you do choose.
You should search on Support Pack MC91, ignore the fact that it is "withdrawn". As a Cat 2 Support Pack it was never supported anyway.
If you are MQ 7.0.1.*, research Multi Instance Queue Managers as a potential alternative to a real hardware cluster solution.

I know this post is about 8 months old but, any updates
Just started to explore on this option: If anybody had implemented MQ7 Multi-Instance Queue manager HA(ACTIVE/ACTIVE) using Red Hat Cluster Suite if so. Please point to any suggested sources and document links to set this thing up.
Will be of great help
Thanks  |

Multi-instance is different from hardware clustering, so don't confuse the two. The Info Centre contains examples of how to set up an MI queue manager, funnily enough using Linux, so give it a look-over. Please note Mr. PeterPotkay's earlier post in regard to supported hardware clustering solutions.

Thank you for the response. 
To be more clear on what we are looking here is to setup Multi-Instance queue manager using NFS4 file system provided by EMC storage device. But we came across a situation where EMC uses mandatory file locking system rather than a advisory file(Leased based) locking system which is what required for MQ7 to work with NFS4 file system. IBM document says the NFS4 file system provides this but, EMC provided NFS4 file system is mandatory once.
http://www-01.ibm.com/support/docview.wss?rs=0&q1=multi-instance&uid=swg21433474&loc=en_US&cs=utf-8&cc=us&lang=en
Further, Our plan was to use the Multi Instance Queue manager and set up Two(active/passive) configuration on two servers failing over on to each other server(obviously having ports assigned differently when WMB comes into the picture,so that there is no conflict when both QM's are on one server at one given time).
We have tested this setup using NFS4server on a linux box connecting to a nsf4 file system on a SAN disk and it worked fine.
Now we are looking into the option of using Red Hat Cluster Suite for both (software/hardware fail over). Probably the link below might be applicable for only of one Multi-Instance queue manager but out requirement is to have two MIQM's.
http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=/com.ibm.mq.amqzag.doc/fa70230_.htm
Please provide any further information on how this can be accomplished |

I'm not sure what you mean by "two MIQMs".
If you want to achieve active/active configuration on two separate machines, you can create two separate queue managers that have the same logical setup. You can then make each QM an MI with the second instance being on the other machine.
This is really an overlapped active/passive setup. There is absolutely no way with any MQ level or HA technology to create a truly active-active queue manager. MQ just doesn't work that way.
So as long as you are thinking of "two MIQMS" as "one MIQM" and "another MIQM", then all setup is the same for each MIQM as it is for "one MIQM". |

| Two (MIQMs)Multi-Instance queue managers on two different servers failing over onto each other. Is this possible with red hat cluster suite. If so, any documentation will help. Thanks |

Once more, and with feeling...no, what mqjeff has suggested to you is it. Why do you keep insisting on asking for documentation to do it with RHCS? If you cannot do fail-over of a queue manager under RHCS, why do you insist on thinking you can do it with MQ queue managers under RHCS?
