Hello, I want help for this very common problem :
my Application1 sends messages (msg1, msg2, msg3) to my Application2.
This messaging system must be fifo : Application2 must receive first msg1 then msg2 … and no message can be lost
Application2 may be down sometimes (for adminstration tasks : upgrade, backup, …) so this messaging system must be asynchronous
I began to create a system :
- Application1 sends messages by calling a IS service1.
- IS service1 sends a message to the IS brocker so it can givesynchronously a return to Application1.
- Than an IS service2 triggered to the message forwards it to Application2. But how this service2 can manage if Application2 is down and to respect fifo ?
Is there an code exemple in SAG website ?
Can you give me the good way to create my IS service2 ?
thanks a lot
I use Webmethods v9.8
