IBM MQ for z/OS configuration

The following steps outline how to configure IBM MQ ; starting and configuring channels and listeners.

1. Start the channel initiator using the command:

   /cpf   START CHINIT  1
   

2. Start an LU 6.2 listener using the command:

   /cpf   START LSTR LUNAME( M1 ) TRPTYPE(LU62)
   

   The LUNAME of M1 refers to the symbolic name you gave your LU (5). You must specify TRPTYPE(LU62), otherwise the listener assumes that you want TCP.

3. Start a TCP listener using the command:

   /cpf   START LSTR
   

   If you want to use a port other than 1414 (the default IBM MQ port), use the command:

   /cpf   START LSTR PORT( 1555 )
   

IBM MQ channels do not initialize successfully if the channel negotiation detects that the message sequence number is different at each end. You might need to reset these channels manually.
