Error description

  • A message that contains message properties was put onto a queue
    by IBM MQ classes for Java application. The message that the
    application was trying to put onto the queue had MQMD encoding
    set to 273 however when the message arrived on the queue, the
    encoding on both MQMD and RFH2 headers were set to default value
    of 1.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of:
    
    - The WebSphere MQ v7.5 classes for Java
    - The IBM MQ v8.0 classes for Java
    - The IBM MQ v9.0 classes for Java

    ****************************************************************
    PROBLEM DESCRIPTION:
    When putting a message that contains message properties onto a
    queue using IBM MQ classes for Java application , as a part of
    the put process, the application  re-encodes the whole message
    including its headers and body using a default encoding and
    CCSID. Therefore the message is not expected have the original
    CCSID and encoding after the put process. The default encoding
    was 1 however,  it did not describe fully how the numeric data
    (binary integers, packed-decimal integers, and floating-point
    numbers) in a message should be encoded.
    

Problem conclusion

  • The IBM MQ classes for Java have been changed so that the
    default encoding is now 273 which describes the encoding for all
    three types of numeric data in a message.  This means the
    messages that are put into a queue will have encoding of 273 in
    MQMD and all subsequent headers such as RFH2.
