I am working on a message flow in which BLOB messages are sent to MQOutput Node.
Flow: MQInputNode -> Compute Node -> MQOutputNode
As all the information about MQ like MQ Manager, Channel, Port and Hostname and Port are setup in database. Currently I have set the Queue Manager and Queue Name property of MQOutput node successfully from ESQL Compute Node. Now the problem is that how would I set the Queue Manager Hostname and Listner Port and Channel Name of queue manager. All this work I have to done via ESQL, can anyone have the solution for this. |

You don't need to do it this complex way.
Assuming you do have a QM running on the same host as the message broker, just put the message to a queue on that local QM.
That queue can be a cluster queue or remote queue in the usual MQ style to forward the messages to another QM.

Why? One of the reasons people pay a lot of money for MQ is that it handles all this sort of thing on behalf of the application. It's very anti-pattern (and in my view not best practice) to have this information at an application level (and IIB is an application in this context).

The MQOutput node doesn't accept connection details via ESQL, only the destination queue manager name and destination queue name. This is by design, for the reasons I give above.

Use MQ in the way it's designed to be used, as my associate describes. If you're using IIBv10 you have a choice of which queue manager to use, while in v9 you're fixed to the queue manager associated with the broker.
Neither version allows you to vary connections at run time via ESQL.
