I have a QMgr A and QMgr B
A has a remote Q defination which is connected to Local Q on QMgr B
There is a application polling on Local Q on QMgr B
The messages following from A to B are persistent messages....Now if the application polling the Q is down....and the local q becomes FULL...then where will the persistent messages go |

| Regardless whether the message are persistent or non persistent once the queue is full, the messages go to DLQ. The only benefits of persistent message is that they survive even shutdown of qmgr. |

The queue full situation and persistence of message are two different design concept. The first is for handling situation when a queue becomes full the persistent attribute makes a message survive even after the qmgr is shutdown. These are not mutual exclusive design.
you can write a dlq handling routine to handle the message in dlq. |
