We have 2 systems.. A and B..
System A is getting messages from system B, and message is ok.. While replying back to system B, there is some junk values at end of each message.
Is there any reason why the junks values coming from where?
If anyone put some inputs could be helpful to me...
Thanks

Bad programming ?
Noise on the line ?

You haven't given us any idea of what sort of junk it is? Can you do a hex display? Is there some pattern to the values? Always the same, always different, what?

Remember, some junk can turn out to be quite valuable. Some "junk" actually turns out to be Antique, or can be sold for good money for scrap. Fingers crossed on that.

Were the variables which puts while reply to queue initialised??

are the 'junk values' beyond the message-length?

We want to know the reason of the junk values. As it is in production, so want to fix it.

Thanks

there is nothing to fix.

beyond the message length
means exactly that,
it is beyond your control.

you are trying to address an area, that you have no business addressing.

now, if these junk values are creating a problem,
the solution is better MQS programmers,
so that they can expalin to you,
why some idiot is attempting to address an area,
beyond what IBM has committed to maintain.

IBM only guarantees the integrity of the data of the message
(defined as message length)
not data beyond the message contained in a buffer or workarea.

or,
attacking this problem from the correct direction:

educate the ignoramus who thinks that this is a problem.
