Hi All,
We are receiving Message from Mainframe. To parse this message we are using an MRM message set(CWF). If we don't set the convert option as Yes in the MQInput node, the parsing fails.
My understanding is that if we use Message Sets, MRM does an implicit conversion to parse the message. Is this correct?
Is there any documentation for this?
We are using WBIMB 5.0 on AIX.
Thanks for all your help. |

No the conversion is not implicit.
You have to check the conversion flag on the MQInput node.
You can as well do an explicit conversion by doing a CAST.
See a few messages back .... this was addressed Yesterday...

| Thanks very much. Is it true even in MQSI 2.1? |

Yes, I think it is.

Please can you point me at this, I looked quickly but couldn't find it?

Normally you don't have to check the conversion flag on the MQ input node. The broker (in this case the MRM parser) will automatically convert the incoming data, from the ccsid stated in the last MQ header in the message into unicode (1200), when the data is parsed and added to the message tree.
If you check the conversion flag, WMQ will data convert the data to the ccsid you specify on the MQ input node, then the broker will convert again from that ccsid into 1200 when parsing. So you end up doing two conversions (unless you specify 1200 as the ccsid of course). Also, if your data is mixed text and binary, you will need to write an MQ conversion exit.
I think we need to understand what your flow is doing a bit more, to work out why you are getting a parser failure. Are you sure that the ccsid in the MQMD and other MQ headers are correct? How are you accessing the fields in the message? What is the exact failure you are getting? How did you create your MRM CWF message model - by import or by hand - if by hand are you sure it correctly matches the data? |

I have set conversion in MQInput node to ccsid 1208. Input MQMD ccsid is 1250.
I have connected MQOutput node and HTTPRequest node as the output nodes for the flow.
When I dump hex content of a message buffer in the output queue, I see that convert flag on MQInput node affects the result in the way I expected.
When I dump hex content of a HTTP request, that's not the case.
Trace node placed after MQInput node, which also has an TDS parser configured, shows also the same result for $Root in a trace file, same as HTTP request body dump, which is not affected by convert flag of MQInput node.
I generate default HTTP headers from input, so that I pass default content type: text/xml; charset=utf-8.
How shall I configure flow, so that HTTP request body is converted to 1208, without writing ESQL or Java? Do I have to avoid somehow internal conversion to 1200? Thanks. |

Did you set the OutputRoot.Properties.CodedCharSetId to 1208? (UTF-8 )

| It seems that would be sufficient. Meaning, I don't have to check the conversion flag on the MQ input node at all. Thanks a lot. |
