Hello!!
Below is the scenario of the problem:-
I've got MQv6.0 installed on one computer and MQv5.3 installed on another
These are the test results:-
1. QM V5.3 (Not in Cluster) ----talks to----> QM V6.0 (Not in Cluster)
Outcome: Success
Description:QM V5.3 Sender Channel Running. Message sent successfuly.
2.QM V6.0 (Not in Cluster) ----talks to----> QM V5.3 (Not in Cluster)
Outcome:Failed
Description:QM V6.0 Sender Channel on Binding/Retry State.
3.QM V6.0 (Not in Cluster) ----talks to----> QM V5.3 (Clustered)
Outcome: Success
Description:I created a set of ordinary Sender/Receiver Channels in QM V5.3 (Clustered) to talk to QM V6.0 (Not in Cluster).
a) QM V5.3 Sender Channel Running. Message Sent Successfully.
b) QM V6.0 Sender Channel on Initializing State.
4.QM V5.3 (Not in Cluster) ----talks to----> QM V6.0 (Clustered)
Outcome: Failed
Description:I created a set of standard Sender/Receiver Channels in QM V6.0 (Clustered) to talk to QM V5.3 (Not in Cluster).
a) QM V5.3 Sender Channel on Initializing State.
b) QM V6.0 Sender Channel on Initializing State.
5. QM V6.0 (Initially not in cluster) ----joins cluster----> QM V5.3 (Clustered)
Outcome:Success
Description:Cluster Sender Channels Running. Message sent successfully.
6.QM V5.3 (Initially not in cluster) ----joins cluster----> QM V6.0 (Clustered)
Outcome: Failed
Description:Cluster Sender Channels Running.
But Clustered QM V5.3 unable to see Clustered Queues in QM V6.0.
The experiment was done a few times and the results were consistant. Does anybody have any pointers or solutions to overcome the failures?
Thank you~  |

As per your results:
1. Well done.
2. Check the settings on the listener & for any network issues. This scenario works (well it works for me!)
3. Again well done.
4. See 2 above. There's no reason why it shouldn't work.
5. Thrice well done.
6. Is the 5.3 qmgr a full or partial repository? If it's PR it won't see the queues until they're used.

It might be useful to know what platform(s) we are talking about here!

I have tested several different combinations (z/OS, Windows, Solaris, AIX ...) with different MQ versions (5.3, 6) clustered and not - without any problems.
Have a look at the error log files of both QMgrs. You should see a more detailed description, what exactly is going wrong.

Make sure that the channels in 6.0 don't have an incompatible attribute set. If you have compression set make sure that NONE is present on the settings (usually the last item on the compression list).

Hello again!!
Thank you all for your inputs. I reckon that it is a network issue.
Once again, thank you!  |

Hi,
My scenario maybe slightly different from yours described above.
I have 2 full repository qmgrs in a cluster, say MQA6 & MQA7 running in LPAR1 & LPAR2 respectively on z/OS. There is 1 cluster namelist in this cluster say NAMELST, in it contains 2 cluster names CLUS1 & CLUS2.
In CLUS1, the 3 partial repositories qmgrs are running on 3 AIX machines with MQ V5.3.1.
In CLUS2, the 2 partial repositories qmgrs are running on 2 AIX machines with MQ V6.0.
My questions:
1. Can I upgrade 1 full repository qmgr say MQA6 in LPAR1 to V6.0 while keeping MQA7 in LPAR2 in V5.3.1? Will the clustering work?
2. What are the possible issue and what precaution I need to undertake?
Thank you for your advice.
.Hoe San. |

As long as you do not use any of the new attributes it should work without problems.
