Regarding Syn-Asyn Bridge

[Former Member]

Hi All,

Can any one explain the following:-

In Syn-Asy bridge, we are using Reveiver Step( open Syn/Asyn), Send step(Asyn), Receiver step(Asyn), Sendstep(close syn/Asyn bridge). In this case receiver is Asynchronous system, so we are taking response from Asy system?(i.e., 3rd step from above flow). This means receiver system in called as synchronous ( send step-request, receive-step response). Please explain why we are taking response from Asyn system in syn/asyn bridge?

Hi Ajay,

Look at this blog to get your ans.

Hi Ajay,

As you said is perfectly correct that we receive response from the Asynch system but synchronously.

As in the synch/asynch bridge, the synchronous business system sends request synchronously to the Integration Server (BPE) which in turn forwards that request asynchronously to the aynchronous business system(receiver). This receiver sends the asynch response to BPE back which is then sent back as anch response to the sender that is the synchronous business system.

Also refer to the topic Sync/Async Communication in the following link
