What is meant by Synchronous and Asynchronous Business System ?

[former_member189387]

Hi friends ,

Can you please give a detailed description about the Synchronous and Asynchronous Business System .

Why we are using Synchronous /Asynchronous Bridge in BPM ?

sync systems are those who can handle request as well as response ,whereas async systems are those who handle only one way communication(either request or response).

we use sync async bridge to join these two systems together so that data can be easily transferred.

Hi Ahmed,

Suppose there are two systems SENDER and RECEIVER and XI is the middleware.

suppose SENDER is sending a customer no. to the RECEIVER and RECEIVER inturn is sending back the customer details to the SENDER.....

So here both SENDER and RECEIVER system are synchronous system....

similiarly if SENDER is sending some data to RECEIVER ..but the SENDER system dont want any response...the they are asynchronous systems....

To understand the synch/asynch bridge ..go thro' the following links...might be helpful to u.

Hey

>>SENDER is sending a customer no. to the RECEIVER and RECEIVER inturn is sending >>back the customer details to the SENDER.....

>>So here both SENDER and RECEIVER system are synchronous system....

Think of this in terms of a File to RFC scenario,now when we send the request to RFC which in turn will send us back the response based upon our request.now had the File adapter been synchronous,we wouldn't have had the need for BPM in this scenario,but since File adapter does not support sync communication we need BPM.

but if u take the case of HTTP to RFC then as both are sync we dont need BPM.

the deciding factor is not the system which is sending or receivin the message but the adapter ur using to send and receive those messages.

>>similiarly if SENDER is sending some data to RECEIVER ..but the SENDER system >>dont want any response...the they are asynchronous

Yes,you are right

the bottom line is ,its not just the system which decides whether the scenario is sync or async ,you can use the same FTP server(by using File adapter) to send some request out as well as to store the response coming in,but since we use File adapter to interact with FTP server,we can't do a sync scenario hence FTP becomes a async system.

Note:we can use modules too instead of BPM to handle response for File adapter after SP19)

Hi Rangarajan,

Business System are representing real systems, they dont have such behaviors.

Synchronous message flow means the sending application is waiting for response before further processing, Asynchronous means there is no expecteded response.

Scenario where Synchronous call is used are - RFC , Webservice etc

here we send few parameters and execute the function or services and get back the responce from the system.

Asynch is used in all scenarios where u are just reading , inserting Or updating

message like file scenario, DB, JMS read etc

Asyn- Sync : If u have a requirement like read parameters from a File and pass them to a webserivce and wait for the responce from webserivce transform them and write to a file in these scenarios u need a bridge between the syn-async

Hi,

Asynchronus means the msg is going and no reponse is coming.

Synchronous means for every request response is comin back.
