Hi,
I'm using base Java to extract the messageId from an MQMessage object. I would like to use this message identifier, which looks something like [B@e0be38, as a unqiue idenfifier in my database.
Can be guaranteed that the messageId would always be unique? If not how can I ensure the MQ always generated a unique messageid?
Thanks
Jason |

If the sender of the message has let MQSeries generate the message ID, then yes it is unique.
One thing to be aware of, is that the message ID is a byte field, not a string.
Cheers,

The message id is unique. However, what you have printed above looks more like a reference (address) to a message id rather than the actual message id. You might want to make sure you have what you think you have. You didn't mention a programming language. There is an amqsbcg.c that ships with the product that dumps the message id in hex. There is also an amqsbcg.java at
http://www.developer.ibm.com/tech/sampmq.html
that does the same thing with java. |
