Hi,

We are working on hp-ux. Our requirement is to see the message Identifier of the message in MQMD. We have MO03 tool installed in our m/c. when i use amqsbcg to browse the message i am getting the msg id, but in hex format. Is there any command to get the msg ID in ascii format. Can you please help me out in this regard.

Regards
L.Pradeep

Most of the ASCII characters that are converted from the message id do not have a printable representation. How will you be able to pass this ASCII value to your program? Your safest bet is to get based on hex value.

You can also try the ma01 support pac or rfhutil to get based on message id

This is because the MsgId is a byte array 24 bytes long, not a string. It can't be represented in ASCII unless you're not using the system generated value but setting it deliberately to an ASCII string.

In which case it's still a byte array holding the string as hex values! There are numerous discussions on the forum of:

a) Why treating msg or correl ids as strings is at best foolhardy and at worse dangerous

b) Why not using system generated values is at best dangerous and at worst lethal.

The search function is your friend.
