Error description

  • On a WebSphere MQ queue manager A, a sender channel 'A.B' was
    defined with a valid IP address pointing to the queue manager B,
    a valid transmission queue and TRPTYPE set as TCP.
    
    On queue manager B, a receiver channel 'A.B' was defined with
    TRPTYPE set as LU62 and listener was defined with TRPTYPE set as
    TCP.
    
    In spite of the sender-receiver channel having different
    TRPTYPE, the channel moves into RUNNING state and the "PING
    CHANNEL" command completes successfully.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All the users who define the sender/receiver channels with a non
    default TRPTYPE.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    While accepting transmission session during communication
    establishment MQ didn't check for the TRPTYPE between the sender
    and receiver channels. The channel communication was established
    if the sender channel and the receiver side listener had the
    same TRPTYPE disregarding the receiver channel TRPTYPE.
    

Problem conclusion

  • The code changes have been made to check the TRPTYPE of the
    sender/receiver before establishing the communication.
