Hi,

The new feature called direct connection has two types of modes.

1.P2P connection.

2.Mediated via message broker.(Integration server is acted as message broker)

In case of P2P connection we dont need PI as a middleware as it does not need that.

Consumer(application)---Webservice Runtime-----Provider

Only PI ESR can be used for Service interface designing (Stateful can be used)

We need to publish the webservice (wsdl) to the UDDI(service registry)

Can use SAP as a provider(proxy) and any consumer application can consume the wsdl.

For brokered service: only stateless and Stateless XI 3.0 compatible can be used as interface pattern.

Consumer(Sender)----PI(WSRM)-----Prider(Receiver)

WS RM adapter can be used for guaranteed delivery in case of async service.

cheers,

Abhishek.

Hi Pankaj,

Check out this article [Point-to-Point Direct Connection Design and Configuration in SAP using PI 7.1|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b00bbb77-75bc-2a10-6b9a-a6f8161515a6?quicklink=index&overridelayout=true] .

there are situations where u do not need the transformation , routing etc features of PI...so in short you do not your messages to go through PI in runtime...you will use Direct connection in this case...but when u use DC u will not be able to use any feature of PI.

There is a object called direct connection in PI where u create the object...but at runtime it will not be called.

This is just so that there is central configuration.

DC improves performance but again it is a point to point connection without middle ware
