I am new to webmethods (rather XPI) (so pardon me if I sound insane)
This is a neat implementation of the master-slave patter in the WM world.
The only limitation being that the source application (order) will not be able to integrate the order insert into its transaction context.

RE ur “in memory latch” alternative it sure is a performance enhancer although I have 2 quries

  1. If no canonical key is generated which links the source and target ids how will we be able to link them in the future (if we do not intend to use a P2P integration)
  2. When does the latch classqualify for garbage collection.
