Hi,
We have the need to generate a unique identifier as part of an xml message. The third party vendor we are sending the xml message to can't read MQMD.Msgid. I was thinking of generating something like QMGR+PutTime which I think has milliseconds. Can anyone think of anything better to use? Thanks.

You could also use UUIDASBLOB or UUIDASCHAR functions.

Thanks Kiran!
Will those functions guarantee uniqueness?

Hi Kiran,
I know this topic have been closed for long time. 
But looking for the same issue at here, If i want to limit the value length to the length i want. Can we do it with this function or do you have any other idea how to creat a unique number with limited length we specify?
Regards

You could use UUIDASCHAR and then take the rightmost substring to the length you need.
But the smaller the number, the less unique it will be.
You could select an incrementing id column from a database.

Thanks Jefflowrey,
I try on it.
Other thing is can i know the length for the message id in MQMD?
Know i getting 49 char, it will alway 49 char?
In the MQ Series manual i can get 24byte for msgid.
Just want to double confirm.
Regards

That's the length of the message ID. 24 bytes long.
When you represent 24 byte values as hex representations, then you get 48 characters.
But if you want a Unique Message ID, just set the MQOutput node to create a new one.
