MQSeries.net :: View topic - Create new output message using MRM in and MRM out.

Nick · Posted: Wed Mar 07, 2012 8:24 am Post subject:

I have searched for a simple description of how to accomplish adding a field to an existing MRM message. In the process I have created a second message definition in the same message set with the added field. I am using a compute node to do as follows:
Set OutputRoot = InputRoot;
Set OutputLocalEnvironment = InputLocalEnvironment;
Set OutputExceptionList = InputExceptionList;
Set OutputRoot.Properties.MessageFormat = 'CWF';
Set OutputRoot.Properties.MessageSet = 'N03LEN4002001';
Set OutputRoot.Properties.MessageType = 'brand-vehicle';
IF OutputRoot.MRM.mtype = 'CYCLE' THEN
CREATE FIELD OutputRoot.MRM.brand;
Set OutputRoot.MRM.brand = 'Harley';
PROPAGATE TO TERMINAL 'out1';
END IF;
...

brand-vehicle is the definition file name of the output message definition file.
I am getting errors that have me go in circles.
parsing the input correctly as in:
(0x01000021:Name+):MRM = ( ['mrm' : 0x806e8f0]
(0x0300000B:NameValue+):wheels = '.FOUR' (CHARACTER)

(0x0300000B:NameValue+):engine = 'VTWIN' (CHARACTER)
(0x0300000B:NameValue+):fuel = '93OCT' (CHARACTER)
(0x0300000B:NameValue+):mtype = 'CYCLE' (CHARACTER)
)
)

Error is as follows:

I am trying to understand what is meant by 'An Attempt was made to parse/write but no descriptor was loaded for the CWF worker' but can not figure out what descriptor needs to be loaded?
Please advise, thanks
