adapter

which adapters is synchronous and asynchronous??

[STALANKI]

First you need to differentiate between asynchronous and synchronous.

Syncronous:Sender will send the request and wait for the response from the reciever.Reciever will send the response back after executing the request.The message state is alive in XI until the resposnse is sent back to the reciver.

Asynchronous:sender will send the request and carry out it z tasks and does wait for any response from reciever.

You ask yourself why file adapter is asynchronous?Is file system intelligent enough to wait for a response?How can a file system send response?

Hope it is clear.

Hi

Adapter engine supports both Synchronous and Asynchronous delivery.In XI terms these are described in terms of Quality of service(QoS)descriptor.

XI supports QoS Best Effort,Exactly-once,Exactly-once-in-order.

These are equivalent to RFS types Synchronous RFC,Transactional RFC,Queued RFC.

Adapters that suppoport a QOS of Best Effort are Synchronous.

Adapters that support QOS of Exactly once and Exactly Once in order are Asynchronous.

Synch and Async --

HTTP, JDBC, RFC,SOAP

Asynch only--

File, JMS, IDoc.

Check Quality of service column ,

BE(Support Sync),EO/EOIO(Async).

Thanks,

hi bhavesh,

can u explain y file and idoc adapters is asynchro and others r both

[bhavesh_kantilal]

Hi,

File and Idoc adapters support a QOS of EO and EOIO and not BE and so only Asynchronous Porcessing.

Hi Raj,

File and IDOC are Asyn because of QoS.

There is nothing like IDOC synchronous. You can use IDOC Acknowledgements instead.

The below links will help you configure the same:-
