Hi,
A server 'X' is connecting to 'Y' via s server connection channel. Now a clone of 'X' has been made 'Z'. Communication should be established between Z and Y as well.
But as far as I know, Environmental variables(MQ SERVER variables) are set in such a way that the channel can talk only to one dedicated destination.
What should I do to establish connection between Z and Y without interrupting the connection between X and Y via a server connection channel |

I'll assume you mean "an application on server 'X' is connecting to 'Y'". If you don't, you're in a world of hurt.

Yes. So X & Z both need an MQSERVER variable that describes the connection. Y doesn't have that variable.

Set up MQSERVER variables as needed on X & Z.

More precisely, MQSERVER= is an environment variable. Environment variables need to be set/exported into each and every shell where they are to be used.
One or more shells can set/export the same MQSERVER= environment variable to a single SVRCONN channel at the MQ server.

Or isolate each client by giving each a discrete SVRCONN of its own, and better to use a CCDT file - you can't secure the connection with TLS if you use the MQSERVER variable.

Could you please tell me will it work if we give two connection names separated by a comma in the below syntax
Channel name is same
export MQSERVER='ChannelName/TransportType/ConnectionName' |

Why do you need to? Both X & Z are connecting to Y so the MQSERVER variable only needs details for Y.

I have set the environment variables for Z. But the connection hasn't been established between Z and Y.
There's nothing logged in the logs. |

How do you know this? What reason code was returned when the application tried to connect? Or did you just see nothing happen when you set the environment variable and just assume it wasn't working?
(Hint: If you post "because the SVRCONN status doesn't show as running" many people, including me, will snort with derision)

Please also confirm you mean "I have set the environment variable on Z with the values for Y".
If you don't mean that, I've found your problem.

No reason code was returned.
yes, I have set the environment variable on Z with the values for Y. |

So the application issued an MQCONN call (or JMS equivalent) and got no reason code? Not even a zero?
We assume you mean it didn't receive a non-zero return code. So what makes you think it isn't working? What error did the application in fact throw?

More explicitly:
1. Exactly how did you set the environment variable. Please post the command(s) you entered and responses you received.
2. Exactly how did you test to see if setting the environment variable worked? Please post the command(s) you entered and responses you received.
3. Exactly and precisely where did you look for errors?

I used the following command to set environment variable
export MQSERVER= 'channel_name/TCP/IP(port)'
The app team confirmed that the communication is not happening.
(Channel status in X
AMQ8417: Display Channel Status details.
CHANNEL(XXXXXXX) CHLTYPE(SVRCONN)
CONNAME(aaa.bb.cc.d) CURRENT
STATUS(RUNNING) SUBSTATE(RECEIVE) |
