Hi All,
I have some different requirement than mentioned in above thread,
Scenario :
I have two flows ( Flow1 & Flow2)
Flow1 has two MQInput nodes, one for REQUEST & one for RESPONSE (All with its default Transaction & Instances properties)
Flow2 has only one MQInput node.
Now the flow of the message is :
[A] Flow1-->MQInput(REQUEST)-->Node1-->Node2....-->Flow2
[B] Flow2-->MQInput-->Node1-->Reply to Flow1
[C] Flow1-->MQInput(RESPONSE)-->Node1-->Node2...(FinalOutput)
I have to store some data in the first flow [A] to retrieve in [C] flow using shared variable, as localenvironment & environment variables will not work here.
Now if I have multiple instances of the Flow1 then how am I going to handle the data stored in shared variable for overwrite stuff (shared variable in the first instance will be overwritten by second instance) .
Please suggest. |

You have three options:
1. solidDB in-memory database.
2. Singleton.
3. SHARED.
My preferred options are in order of preference.

You can construct the shared data in any way you want, to ensure that it's not overwritten.
For example, you could create a shared ROW variable and then use the request id as the name of a field in the row, and then the rest of the data you need to share as children under that.
Then you just need to make sure that you properly delete the shared data row in [C].
pretend you're writing Perl and the shared variable is a hash. |

or
[A]Request -> fan out
[B]Service
[C]Response -> fan in
Have fun
