APAR status

  • Closed as program error.

Error description

  • The sample dead-letter queue handler, amqsdlq, uses
    MQGMO_CONVERT when moving messages. The MQGMO_CONVERT option is
    used to ensure the MQDLH message header can be understood by the
    program, however it also has the unwanted effect of converting
    messages to a different CCSID.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Any users that use amqsdlq are affected
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The amqsdlq program uses MQGMO_CONVERT when issuing MQGET to
    remove a message from the dead-letter queue. When the message
    matches a forward or requeue rule, the program then issues an
    MQPUT to put the converted message to another queue.
    
    The amqsdlq program should not convert the message.
    

Problem conclusion

  • The amqsdlq sample is changed to obtain a converted MQDLH
    message header using MQGMO_CONVERT from messages on the
    dead-letter queue in an initial, additional and non-destructive
    MQGET. The MQGET that is used to remove the message from the
    dead-letter queue omits the MQGMO_CONVERT option to preserve the
    original message payload.
