MQSERVER

MQSERVER environment variable is used to define a minimal channel. MQSERVER specifies the location of the IBM® MQ server and the communication method to be used.

You cannot use MQSERVER to define an SSL channel or a channel with channel exits. For details of how to define an SSL channel, see Protecting channels with SSL.

ConnectionName must be a fully-qualified network name. The ChannelName cannot contain the forward slash (/) character because this character is used to separate the channel name, transport type, and connection name. When the MQSERVER environment variable is used to define a client channel, a maximum message length (MAXMSGL) of 100 MB is used. Therefore the maximum message size in effect for the channel is the value specified in the SVRCONN channel at the server.

To set this variable use one of these commands:
  • For Windows: 
    
SET  MQSERVER=ChannelName/TransportType/ConnectionName
  • For UNIX and Linux® systems: 
    
export  MQSERVER='ChannelName/TransportType/ConnectionName'
  • [IBMi]For IBM i: 
    
ADDENVVAR ENVVAR(MQSERVER) VALUE('ChannelName/TransportType/ConnectionName')
  • [z/OS]For z/OS® 
    
export MQSERVER='SYSTEM.DEF.SVRCONN/TCP/AMACHINE.ACOMPANY.COM(1414) '
TransportType can be one of the following values, depending on your IBM MQ client platform:
  • LU62
  • TCP
  • NETBIOS
  • SPX

ConnectionName can be a comma-separated list of connection names. The connection names in the list are used in a similar way to multiple connections in a client connection table. The ConnectionName list might be used as an alternative to queue manager groups to specify multiple connections for the client to try. If you are configuring a multi-instance queue manager, you might use a ConnectionName list to specify different queue manager instances.
