Need your suggestions wrt to below issue. javascript:emoticon(' ')
Here are my Configurations :
XML to MRM conversion - WMB flow .
WMB8 is on Windows server , data is being sent to our MF system MQ queue v7.
When i read the data in WMB debug mode .. i see data is in correct order. But when output message is put to queue on z/os .. pack decimal fields are in reverse order.
I see CCSID and Encoding on output message are correct.
Encoding : 546 CCSID : 500
Format : 'MQSTR ' |

Intel stores numbers in reverse order from z hardware. Big-endian vs. little-endian.
Is the consuming application complaining (throwing an error)? Does the consuming application request data conversion?

Yes consuming application is failing - as even the sign field is also in revese order - example : Hex code 5F180000 .. expecting 185 here . |

Have you read about data conversion, such as http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/index.jsp?topic=%2Fcom.ibm.etools.mft.doc%2Fac12380_.htm

Am sorry , if its dumb answer - I assume you are asking about MQGet - Its not . Application is not requesting data conversion. |

Please can you supply the following info:
- the logical value of the packed decimal ( for bonus points, prove it by showing the output of a Trace node )
- the exact sequence of *bytes* that the MRM parser is writing. Make sure that you intercept this value on the output queue before it gets to the z/OS system.
- the exact sequence of bytes that you need.
- the definition of the MRM packed decimal field
Armed with that information, it should be possible to give accurate advice.

Logical Value is : 185 .. I have mapping node in place for data conversion.. Trace did not show value being assigned.. but When i use debugger Message tree shows .. correct value ie 185

I tried with CCSID- 500 and Encoding - 785 . am getting correct value now.
Thank you kimbert and bruce2359 for your advise. |
