Well, if you just have a single process with a single thread doing gets from a single queue, and you're using FIFO order (default), then you'll be sending out messages in the order you're getting them.
But there's no guarantee that this is actually "in sequence".
They may have been sent out of sequence already, they may get streamed to the receiving customer in sequence but then get load-balanced across a cluster or something....
There's a discussion in the Intercommunications manual about how the network between two queue managers can change the sequence of messages received.

Thanks for that,
Yes we are using one app to put the messages on the queue. it does do the put command in sequence then it goes over 3 QM's, after that is is out of sequence.
where can I find this Intercommunications manual ....
I really would like to read that section you are talking about. |

That wasn't even in response to your message...  You actually beat me to the punch once!

Hi,
Anyone has an example java program that requests a coa message?

Some other things to consider:
Is every message you put a PERSISTENT message? This will be specified either in the pmo or in your queue remote definition (or both, depending).
Take a look at your sender channel definition. Does it specify NPMSPEED(FAST)? Does the sender channel on the intermediary queue manager specify NPMSPEED(FAST)?
Is there a program on the intermediary queue manager that re-processes your message before putting it to the transmit queue to the destination queue manager? Does it create a non-persistent message?
Non-persistent messages intermixed with persistent messages AND with NPMSPEED(FAST) can affect the downstream delivery order.
Is your queue manager in a cluster? Is the intermediary queue manager or the destination queue manager in a cluster?
Are there multiple paths from the originating queue manager to the intermediary queue manager? Or from intermediary queue manager to the destination queue manager? |
