APAR status

  • Closed as program error.

Error description

  • DESCRIPTION:
    WebSphere MQ is not honouring the value supplied by the exit in
    the ExitSpace field of the MQCXP structure.
    
    You may see one of the following errors: AMQ9195 or AMQ9209.
    
    WebSphere MQ trace of the problem will contain
    rrcE_EXIT_DATALEN_GT_MAXSEGLEN.
    

Local fix

  • If the MQRC_TRUNCATED_MSG_FAILED return code can be avoided by
    passing in a larger buffer up front then this should cause the
    error to be avoided.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who rely on the ExitSpace field of the MQCXP structure may
    encounter this problem
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A channel send exit should expect to be able to use at least
    ExitSpace bytes of the transmission buffer for its own purpose.
    If a MQRC_TRUNCATED_MSG_FAILED return code is returned to a
    consumer then the send exit receives a buffer length that does
    not reserve the requested ExitSpace.
    

Problem conclusion

  • The code was corrected so that the buffer length that is passed
    to the send exit reserves ExitSpace number of bytes.
