A customer has placed a DATAGRAM message on an MQ Queue which contains two properties:
fileName
mcd.Msd
This dot annotation is apparently some new heirachical property function of MQ.
Unfortunately, what I find is that, if I try to read messages with this "mcd.MSD" property, when the code hits this line:
| Code: |
| recvMsg = Consumer.ReceiveNoWait |
XMS throws the following exception:
| Code: |
xmsEx
{"CWSMQ0123E:
The property name JMSType is not valid to be set to mcd://none.
The Value is not valid for the property. Check the property name value are correct."} IBM.XMS.XMSException
|
I have two questions.
1 - How can I put a heirachical property such as "mcd.Msd" on a queue, using RFUtil ? (I've already tried, it didn't like the dot notation - the message contained no properties).
2 - Why does XMS think the value "none" is incorrect - that is the value of property "mcd.Msd" when viewed in MQ Explorer (see below)

The answer is probably somewhere on this IBM KB Document, but I don't understand it.
What is a "message domain" ? |

Interestingly, if I browse the messages using RFHUtil, the usr tab, which lists the properties, only lists the first of the two named properties, "fileName", and not the second property, "mcd.Msd".
It would be perfectly fine if my code could be adjusted to also do this, as I'm not interested in the 2nd Property "mcd.Msd", only the first one, "fileName".
Any ideas how I might do this? |

Message properties are new in v7.

The "mcd" are system properties (this one is a message set id) and used internally. All the properties you set are "usr".

No idea (XMS is not my thing) but I'd raise an eyebrow if I saw it. If it really was "none" (which is plausible) I'd expect the property to be missing completely.

mcd.msd is a WMQ specific attribute. mcd.msd attribute contains message type and valid message types are "jms_text", "jms_bytes", "jms_object", "jms_map", "jms_stream" and "jms_none". Any other value for this attribute will cause XMS to throw an exception. In your case you have just "none".
To set this attribute using RFHUtil, select any of the radio buttons under "JMS Message Type" in "JMS" tab.
