Hi,
I am using WMQI2.1 and have been using 'Environment' to keep variables in my message flow. e.g.
SET Environment.Variable.ABC = 'PQR';
I have meny of variables (around 20-25) set into environment in my message flow that I am using in my last node to put the values from environment variables into an output XML file.
Now I am apprehensive thinking that if these will create any problem when lots of messages will be flowing thru my message flow. I am not sure abt whats the scope of Environment variables in a message flow. if any of the environment variables still available when another message is flowing thru this flow..it may impact the expected output message.
Please help....
Kindly tell me where can I get more details about it?
If Environment is not a correct thing to use...then whats the best alternative? |

Environment is the correct thing.
No part of any of the message trees are shared between invocations of a flow.

Hi
For information, in message broker V6 you can have declare variables of any datatype that are shared either "node wide" or "flow wide" accross theads. You can also declare variables of type ROW which allows you so create shared trees. In addition, all variables that are shared keep their values from one message to the next, until the flow is stopped (redeployed to, stopped, etc)
regards,
MGK
