Hi,

I have a query regarding the Sender channel.

When the Sender channel goes to the retrying state due to batch sequence number not matching with the receiver channel.

What I observe is that the message are no more in tranmission queues.

Some of say its in Sender Channel but I do not know really message can hold be holded in Sender Channel the message it just transferes thro the sender channel.

If Iam not wrong the Sender channel should not hold the message in any conditon.

Its the responsibility of the Transmission queue which holds messages in case of any problem.

But Iam unable to see the message ???

Can U put light on this ???

Channel operations are transactional.

If a message is "in transit", it is still on the transmit queue, however it is not visible because it is within an uncommitted unit of work.

When this has happend to us we have to

stop the SDR
stop the RCV
Resolve the SDR with *BCK (this will roll the message back for you to see)
reset the SDR (gets the numbers back in sync)
reset the RCV (gets the numbers back in sync)
start the RCV
start the SDR

Hi guys,

We are developing a utility for avoiding the batch sequence number in the channel.

Do you know Java API / mqsc command /pcf command which will help me to get the bacth sequence number
