Different IP for synchronous Webservice scenario

[former_member190358]

Hello SAP PI Members,

We have planned for data centre migration from Oracle to DB2.

As part of migration, the incoming and outgoing public IP are different now. earlier they were same, but now they are different.

However there are few synchronous RFC to Webservice scenarios . The partners are saying that they will only send the response to the IP they receive the request from .

Well, internally for me its the same IP . Because change is in public IP and not SAP PI.

I want to know that,  technically is it possible to have a synchronous scenario with different incoming and outgoing IP's  ?

Regards,

Ravi

Technically it is possible. Please talk to network team. One way is use F5 networks (load balancing and much more featured server) between PI and receiver system.  Send message from PI to F5 and in F5 configure the ip address to forward request from F5.  Similary from the receiver system send the message to F5 but in F5 configure to return the response in different IP address. F5 address remains same with respect to PI and receiver system.

Hello Baskar,

We have a load balancer at our end . But what if the partner do not have this facility of F5, then how does he make this switch .

Hi Ravi,

Load Balancer (F5, Web Dispatcher) is a device that acts as a Reverse Proxy and distributes Network or Application traffic across a number of servers. Neither PI or your Sender/Receiver needs any additional functionality to use it.

F5 network or similar load balancer is kept in pi environment.  This is configured to route the inbound and outbound message according to the requirement.  As for as partner is concerned they would  route the message to F5 not to PI directly and receive message from PI via F5.
