I have two local queue managers running on windows R12 server
For clarity, does "local" here mean that both qmgrs are in the same o/s instance? Same LPAR?
Thiru Yes both are running in same OS and LPAR.
Thiru wrote:
... and
those are running absolutely fine but after few days of qm restart (monthly failover)
How do you "restart" these qmgrs? What commands are issued?
Thiru We will open failover cluster manager and right click on the role and move it to second node, then automatically all the resources will move to passive node
Thiru wrote:

from MQ explore and I am not able to view the objects but i can be able to access them from cmd prompt.
Do you mean that you can issue runmqsc cmd, then DISPLAY mqsc command? Or some other cmd prompt commands?
Thiru I can see queue status and channel status etc.

I tried to connect again but getting below error. facing the issue in MQ V9.2.2.0 and MQ V9.1.3.0 as well.
Your original post says that you have two local queue managers ...
I'm confused here. This seems to say that you have this same issue on other queue managers, as well. Please clarify
Thiru: I mean to say, I have two different environments and two different installations.
one environment have MQ installation of V9.2.2.0 and another one is having V9.1.3.0 and servers and IP's and everything is different, but issue is same, and each environment have two queue managers.

Why not use MQ Explorer on a remote machine, e.g., your workstation? There is very little utility to having multiple instances of MQ Explorer just to "manage local queue managers", especially when those "local queue managers" are on the same machine, especially as the user data may be stored in a roaming profile...

Please be precise with your replies.

cmd prompt usually means DOS shell. Exactly what cmd do you enter to access them?

So this is quite confusing. On the one hand you have told me that you can ping the IP address that MQ Explorer is using to try to connect to the queue manager, but on the other hand you have shown that MQ Explorer is not using a Client connection with an IP address, but is in fact using a Local bindings connection to the queue manager.
If the queue manager is not running on the same machine as the MQ Explorer, it will not be able to connect to it using a local bindings connection.
Can you tell us why you do not use the IP address you have been telling us about in your MQ Explorer settings?
Cheers,
Morag

Thiru: The comment was by mistake actually what I meant to say is. I tried ping the server IP address from different servers, but they are all pingable as I mentioned before MQ server and MQ explorer both are on the same Windows Server machine |

Correct me if I've misunderstood:
- you have MQExplorer installed in the same o/s as the qmgrs
- you are connecting MQExplorer to local (same o/s) qmgrs
- one or more or all local qmgrs are visible in the Navigator pane, but
- expanding one or more of the local qmgrs, does NOT display object details in any Content panes
Further, does the same MQExplorer instance display any qmgrs and their objects successfully?
I've seen this behavior occasionally. Try this:
- stop the MQExplorer
Restart the MQExplorer with options to clear Eclipse cache
- strmqcfg -c
or
- strmqcfg -i
Please tell us the results.
You might want to try the new-ish MQConsole to see if it produces correct results.

Thiru: Tried those as well but no luck and results are still same.
I also tried to add these queue mangers to another instance of MQ explorer running on different server and below is the reported error.
could not establish a connection to the queue manager - reason 2538. (AMQ4059).
You might want to try the new-ish MQConsole to see if it produces correct results.
Thiru: Please advise the steps.

Reason code 2538 (MQRC_HOST_NOT_AVAILABLE) is an error you would get when trying to make a client connection. Are your queue manager's configured to accept client connections? Earlier you said:

First you need to set up the mqweb server running on the machine where your queue manager resides. If your queue manager admins are not allowing client connections, I suspect they may not want to open up a REST interface ovr HTPP to the queue manager either?

Hi Thiru,
Is it possible that your listener hasn't started properly as part of the failover?
You say that when you have this problem, you are still able to use runmqsc. Can you use DISPLAY LSTATUS(*) to check that your listener is running next time this happens?
Cheers,
Morag
