MQNAME
MQNAME specifies the local NetBIOS name that the IBM® MQ processes can use.
See Defining a NetBIOS connection on Windows for a full description and for the rules of precedence on the client and the server.
To set this variable use this command:
SET MQNAME=Your_env_Name
For example:
SET MQNAME=CLIENT1
The NetBIOS on some platforms requires a different name (set by MQNAME) for each application if you are running multiple IBM MQ applications simultaneously on the IBM MQ MQI client.
