| I have a message flow which reads messages from an input queue,Is there any way we can design the flow where the flow stops automatically when all the input messages have been read and again it should start when a message drops into the input queue? |

Strange request.
A message flow with a MQinput node issues MQGET WAIT against the queue, it is therefore waiting for the next message automatically.
Normally you process one message in the flow, allow the flow to end and it will then pick up the next message automatically.
You don't need to use the MQGET node to empty the queue but if you decide to do this, then when the queue is empty just let the flow end.
By "ending" the flow - it simply returns to the MQinput node to await the next message. When it arrives the flow will process it. |

Why would you want to do this?

Hi raghav,
You can use Omegamon for the same by writing a situation for the queue depth. |
