Hi,
In case at MFlow level, 10 additional instances set (Start mode is Maintained and Additional instances are not getting allocated at MFlow Start).
If Mflow has got SOAPInput and MQInput both and all the 10 additional instances are consumed by SOAPInput and a Message comes to MQinput Node, will that wait until a busy thread is released?
Would there be a waiting time to process that message Or that will be timed out?
In such cases it is suggested to have additional instances at Node level and Pool associated with node ?
WMBv8.
Thanks !!

As per redbook :
| Quote: |
Parallel Processing for Input nodes:
The Broker always creates a separate thread for each input node in a message flow. For example, a message flow with three input nodes will be processed by three threads by default. You can specify additional threads for the whole flow using the additional instances configuration parameter of the bar file.
These additional thread instances are distributed between input nodes on a first come first served basis. If you need more even distribution for your input nodes, you can use a separate thread pool for each of them. Select the pool from the Instances tab on the Properties view for each input node during design time. |
That means.. it needs to be set at Node Level and Pool associated with Node (as per the Problem Description, OP)?

Hi shashivarungupta,
can you give more details about your message flow ? does your flow looks like:
SoapInput ---> compute node --> MQInput
?

I would be amazed if *anyone* could construct a flow like that. |
