Hello All ,
I have been working on the MUltiInstance MQ set up and shared the CCDT Fiel to the client application team .
They are able to connect as well .however we have a requirement to find out which QM is active now , and need to log the host and port number in the client application logs .
I got this - "Which namelist is it that you wish to inquire details of? I don't know of a namelist that lists the multi-instance MQ Queue Manager's addresses and ports. You are getting reason code 2067 (MQRC_SELECTOR_ERROR) because MQCA_NAMELIST_NAME is not a queue manager attribute, it is a namelist attribute. You would need to open the namelist for MQOO_INQUIRE. However, the real question is "Which Namelist?"
from another forum - does anyone can help me identify the MQ object that really holds the connection details .
ps- https://stackoverflow.com/questions/57609994/mq-get-multi-instance-mq-manager-connection-list
Thanks in advance ,
yshak |

You could inquire the channel status of your SVRCONN channel and look for the attribute CONNAME.

The conname attribute really only gives you the address you're connecting from. What the OP is after would be the LOCLADDR field that shows the address and port that was connected to, ie the qmgr's IP and the listener port.
Hope this helps

What do you mean by "active?"
By "active now" do you mean the name of the qmgr the application has successfully connected to? Or, do you mean the names of the qmgrs that are defined in the CCDT, and which are currently running?

Thanks for your response .
By "active now" - I meant the current connection from client application to the Queue manager .
basically I am after the connection details like server name and port .
In-case of multi-instance QM - we have two servers one will be active and other one as stand by , so when client application connects to primary if it fails it connect to standby one .So there is a possibility of two connections .
We need to know which connection is active now from application side .
Client application use PCF Agent , MQ queuemanager object etc .(not sure this makes sense here...)
Thanks again ,

You could make use of MQCNO_CD_FOR_OUTPUT_ONLY. This fills in the MQCD structure with the choice made from the CCDT. It was provided so that applications making two connections could guarantee that they both went to the same place, even if a CCDT was in use. However, it also serves to tell the application where the connection was made to.
Cheers,
