Is this MQSI or base Pub/Sub? Which version?
If MQSI, then it sound like you have both subscribers using the same queue. Try changing one of the subscriber identifier bits in the RegSub e.g queue. It is a while since I've used pub/sub but I think this is how it should work. Extract from Programming Guide (2.0.2):
| Quote: |
In general, if a subscribing application has more than one subscription that
matches a publication, only one copy of the publication is sent to it. However, if it
registered with different subscriber identifiers (a combination of the MQSeries
queue, queue manager, and optional correlation identifier), more than one copy
might be sent to the application. |
Alternatively, check that you do have 2 separate subscriptions and the 2nd one is not replacing the 1st. That should be obvious if you, know which of the 13 messages each is getting.
Regards,
Vicky |

i am using AMI to do this.
my situation is i have more than 2 client waiting for the publication, all of the client do a subscription with same queue, same policy and same topic (means that they are same program but running in different pc), so what should i do to make sure all the client get the same publication message?
should i browse the queue or using different receive queue for different client?
kindly thank you |

I think the easy solution is to use a different queue for each client.
