Hi,
I want to know that will there be any performance issue if I
initialise two correlation set while sending message out of
orchestration instead of single correlation set.

Example
I send a message out of orchestration and will wait for some response
file.
If response file is "Y" then I will terminate main orchestration
Else response file is "N" then will wait for the parent message
with some correction.

Question:
Should I initialise the correlation set for receiving second file only
if I receive response file with "N" or I can initialise correlation
straight way without considering response.

I want to know what will be the performance issues in second approach.

Sorry, missed that one :-)

When you initiate a correlation you basically add a temporary subscription
to the message box (a slightly simplified description, but will do I guess)
which will last until the orchestration receives the message(s) expected.

The list of subscriptions (and correlations) is evaluated every time a
message enters the messagebox in order to determine if the message matches
this correlation.

therefore there is an obvious impact on performance for correlation, and not
only for this orchestration.

This is not a major impact as the subscription mechanism is efficient, but
if there are many instances of the orchestration at one time (then there are
many correlations open, and subscriptions on the messagebox) and/or if it
takes time for the second message to come in you should feel the impact.

Hope this helps
