Re: Disappearing cluster queues
Morag, Owing the following reason that cluster exit can choose repository it like, when we define cluster queue (from a member QM in the cluster), we may not see the cluster queue defined immediately. Is it true? Can REFRESH CLUSTER or other means help to make the cluster queue effective immediately. In some case, we found that we may need to put some test message into the new cluster queue to make it effective. However, this approach is not feasible in a production environment. K K --- Morag Hughson [EMAIL PROTECTED] $:.e!G A partial repository will publish information (about it's queues and channels) to two full repositories. A partial repository will subscribe for information (e.g. who hosts the queue called FRED) from two full repositories. The two full repositories used for each subscription will not necessarily be the same two if you have more than two full repositories available. The choice of which full repository used will be, by preference, any that have a manual cluster-sender definition to them and then the standard workload balancing applies to choose between equal choices. So you can control which two full repositories any particular partial uses by defining two manual cluster-sender channels. If you have more than two full repositories, you still should not take more than one off-line at a time, since you could take the only two full repositories that one particular partial is using off-line and therefore that particular partial repository would not receive any updates. If you have a need to take more than one full repository off-line at the same time and your have numerous full repositories, you are advised to alter them to be partial repositories first, which forces the partial repositories using them to remake subscriptions with another full repository, thus ensuring the continued receipt of updates to the resources they are interested in.

Once the full repository receives information from a partial, it then republishes to all the other full repositories. So the assertion that the partials only publish to two fulls is correct.

If FR #3 didn't have all the info, then it wouldn't be a FR. I think you when you define the manual CLUSSNDR to one of your FRs, that FR sends back info to the new QM telling it how to make Automatic CLUSSNDRs to itself, as well as info on how to make Automatic CLUSSNDRs to every other FR it know about, whether it is just FR #2, or FR #2, #3 and #4
MQ Clustering Topology
Dear MQer, We am planning for a regional MQ clustering topology. We are facing some decision on 1 .How to group the QM into cluster (by application, platform etc..)? 2. Where to insert gateway between cluster? Should we put all repositories on zSeries? 3. If some of QM got problems (like machine crash of NT), how to insulate the rest of the QM from the impact (like stacking up of message on other QM or gateway). 4. How is the security concern be addressed if some of the QM would be connected to external parties or QM on DMZ zones etc. Any comment or thought is welcomed? If there is document or redbooks or share presentation (or bibles) on this, I would be very appreciate to know about them.

IP addresses change, but DNS names tend not to. I don't use the host name (VAXX), though, I always use a DNS name like APPL.domain.com. Reason? See #4 below. 2. Every host has a DNS entry setup that points to it, in the format host.domain.com. 3. Every application is further defined by an alias in the format appl.domain.com. 4. Now, I have the networking group assign appl.domain.com as an alias to host host.domain.com. I then connect to appl.domain.com. 5. In the event of an emergency, and we must fall over to the Disaster Recovery system, I have the network group simply realias the appl.domain.com to point to drhost.domain.com, and VIOLA!! in a matter of minutes, DR rerouting is accomplished - there are never many DNS servers in a corporate INTRANET, right? - and there are no required changes to any of the channel or remote queue definitions - host names stay the same, connection names stay the same, etc. After all, isn't that why the concepts of DNS names and aliases and remote queues were all developed to begin with -- to isolate each layer from the other, and reduce the number of external dependencies to a bare minimum. Using my convention, the drastic case of DR switchover and the simple case of application rehosting are both easily accomlished with a couple of commands issued at the network level - the backbone of the company. Reduces all those dependencies to the bottom layer, a single dependency. Hope this helps. David A. Awerbuch, IBM Certified MQSeries Specialist APC Consulting Services, Inc.

Fw: MQ Clustering Topology - Ask for comment and experience
Dear ALL, We have 3 remote sites (with already several queue manager installed at each site) to be connected via MQ clustering (for high availability and simplify channel connection).Now, we are at a point to consider the topology for connecting the queue managers of the three sites. I understand from red book that there were bus topology and Hub-and-Spoke topology for MQ clustering while each topology has its own pro-and-cons. Hence, I would like to seek your opinion, experience and feedback on the selection criteria and consideration. As each of the sites has its own naming convention and interconnection within the sites. Because of it, we worry that a pure Hub-and-Spoke would place additional administration effort to the MQ of each site but bus-topology may not give the simplified channel connectionBecause of this, we are considering a Bus-and-Spoke topology which each site contribute two gateway queue managers and the queue managers are connected in a bus. What is your opinion on this topology? Any concern we need to look at for Bus-and-Spoken?

Re: Hostnames or IP addresses for channel connection names
Using DNS name could free us from caring IP address change. It appears that after DNS resolution (at channel start), the queue manager is in fact talking in IP address.
