WebSphere MQ for z/OS shared channel configuration

 

  1. Start the channel initiator using the command: 
    +cpf START CHINIT    1

  2. Start an LU6.2 group listener using the command: 
    +cpf START LSTR LUNAME(G1) TRPTYPE(LU62)  INDISP(GROUP)

    The LUNAME of G1 refers to the symbolic name you gave your LU (11).

  3. If you are using Virtual IP Addressing, either with WLM/DNS os Sysplex Distributor and wish to listen on a specific address, use the command: 
    +cpf START LSTR PORT(1555) INDISP(GROUP) IPADDR(mvsvipa)

There can be only one instance of the shared channel running at a time. If you try to start a second instance of the channel it will fail (the error message varies depending on other factors). The shared synchronization queue keeps track of the channel status.

WebSphere MQ channels will not initialize successfully if the channel negotiation detects that the message sequence number is different at each end. You may need to reset this manually.
