HI Gurus,
One of my solaris server where Mq was installed has been deprecating and its contents needs to migrate to the new server . UNIX Admin says that he will take the image of the entire old server and will place it in the newly built server and their is no need of installing MQ or Creating QM's again. here i have the following QUESTIONS.
1. will the image process of the old server and placing the same image in different server works in case of MQ-series? is their any constraints in this process. i know the ip address will be changing for this server i will inform the client apps about the new IP. what are all other constraints.
2. there are multiple QM's Running in this server which is having sender and receiver channels with each of them. will they work normally after placing the image of the old server in different server? or do i need to re-create all sender and reeiver channel again. as the new server is having different IP? |

There is plenty of discussion on the site in regard to the effects of 'moving' queue managers, especially any that are in a cluster, so I suggest you search for that information, but I'll provide some observations/questions:

You do not mention the release of WMQ, or whether the move is due to hardware or software being outdated on the server. If software, is your release of WMQ compatible with the flavour of Solaris you're moving to, or will the image be running virtualised?

That question implies that you may have client channels, so renewing CCDT files is a requirement if strict IP Addresses were used in the CONNAME's.

They will not work normally if again strict IP Addresses are used in the CONNAME's, how could they if the IP Address changes?  Just change the CONNAME's in each SDR channel. A little time spent thinking would have given you the answers to most of your questions, without the need to resort to the board.

Thanks for your inputs,
Currently we are using MQVersion: 530.7 CSD07. The migration is not due to any software or hardware outdate. Our Client decided to change all the servers from existing datacenter in Lincroft to the new data center in US. The new servers will replicate the current hardware and software of the depricating servers. |

I strongly suggest that you strongly suggest to your client that they upgrade to a supported version of WMQ.

Yet the client describes the servers you're moving off of as "depreciated". Now obviously this could be an accounting term, which explains the move, or it could mean they're on a back version of the OS. You should check.

It still might not be the case that they're replicating the same levels. It's hard to believe that someone would build a new data centre and not fill it with up to date hardware & software.
In any event, WMQv5.3.7 is out of support and not even the latest version. It won't be tested with any OS or other updates so you're at risk every time the sys admins apply maintenance.
Any problems are also on you not IBM. Ensure whoever manages the business risk is aware of this exposure.

Hi sorry for the late response .
yes you are absolutely correct. Initially i was informed by my managre that every thing will be same as the old server. I have contacted the Admin person and he confirms that OS is going to be upgraded to SUNOS 10. Current setup where MQ is running is SUNOS 5. So if the image of the MQ Placed in the New version of SUN OS will it work? did the MQ 5.3.7 tested on SUN OS 10. do i need to ask the admin person not to upgrade the OS version? Please advice |

The Solaris Sys Admin is probably contractually obliged to upgrade the OS to a supported version, unless the client insists that it remains at an unsupported level, in which case a waiver or other contractual get-out clause should apply - ditto the level of WMQ. If they won't go up to supported levels then the support agreement should be negotiated, documented, and set in stone.
As an aside, I have found the phrase "...we can only support that installation under best endeavours, even in Production..." tends to induce sudden clear vision in the management sphere

BTW i have informed My manager to insists client on the upgradation of the MQ Version. He asked me to first overcome the current suituation of this datacenter migration with out upgradation of MQ.
He inturn asked me which version we need to get upgrade all the benefits that he is going to get with an upgradation of MQ ? as he needs to make client agree for an upgradtion with those benifits.
In my entire project we have two HP-UX servers where MQ version 5 is also running. and another Two solaris servers where 5.3.7 is running. Now can we migrate the Version 5 to MQ 7.0 directly or do i need to migrate to mqVer 6?. |

Given that your applications will not be changing, the most benefit will arise from upgrading to a supported WMQ version.
What benefit is your manager expecting from the o/s upgrade?
Upgrades generally add new functionality (whether you intend to use it or not), improvements in efficiency (which you might use, whether you know it or not), and improved reliability (which you may or may not notice).

Upgrading to a more recent version means it will run on the Solaris 10 OS, and will receive support from IBM if it doesn't.
As to the other benefits of new versions over WMQv5.3.7, you'll find details in the "what's new" section of the documentation. Along with huge numbers of performance & stability improvements.

What you can say to the client is that the cost/benefit analysis of the WMQ upgrade goes like this:
Benefit: Leaving an unsupported version of WMQ that wasn't that good when it was new, which will run on modern operating systems much better than their current version does.
Cost: None. Assuming the client has a license (and isn't using WMQv5.3.7 because that's just what they've got the media for) then the upgrade is free. Some regression testing of course but that rolls up into the testing of the new server installation.
Simple (to use a meerkat rather than a trout).

| Thanks Vitor, i will surf the site and prepare some features which were currently added to the new versions.and will keep forcing my manager To go for an upgrade. But as of now can you people plese confirm what is the last Solaris version whcih MQ 5.3.7 was tested successfully. I need to inform the client about the OS version which they canUpgrade so that the current MQ 5.3.7 will work ? |

Now interestingly (and proving you learn something new every day) Solaris 10 is on the list of OS for WMQv5.3 - I thought v5.3 only went up to Sol 8!
So some version of v5.3 was clearly tested on Sol10, but I would suspect that it was a much later version than CSD 7. So this gives you a couple of choices:
- use WMQv5.3.7 and cross your fingers
- apply maintenance to the v5.3 to CSD 12/13/14 and regression test the new version, but still end up on an unsupported version
- upgrade to a supported version, regression test it and be confident it will all hang together correctly plus have all the advantages that come with WMQv6/7
I know what I'd do in your place, but I'd have trouted your client by now...
