I am preparing for the MQ certification and I need your help on some of the questions
Iam looking for answer on the following question ...

Data conversion is needed between systems with different data representation. The two recommended mechanisms for this are a Get Message Option of MQGMO_CONVERT and a sending channel attribute of CONVERT(YES), respectively. In a customer scenario, both options are accidentally configured. Consider a text message (MQFMT_STRING) traveling from an EBCDIC system directly to an ASCII system via a channel with CONVERT(YES) configured and then being retrieved by an application using MQGMO_CONVERT in its MQGET call. What will be the result of this message being presented for conversion twice?

A. The message will be delivered unconverted with a completion code of MQCC_WARNING and a reason code MQRC_NOT_CONVERTED.
B. The message will be converted twice, resulting in incomprehensible bit patterns.
C. Depending on the message's persistence attributes, it will either be delivered to the dead letter queue or discarded.
D. The message will only be converted once.

Thanks for your help

The answer is D. The message is converted to the CCSID of the receiving Queue Manager. The answer is found in IBM's book, Data Conversion Under WebSphere MQ.

I agree. Here's the link: http://aspose.com/file-tools
