Message Server Vs Application Server RFC string for SAP System

[Former Member]

Hello Experts,

Can anybody tell the difference between SAP System connection RFC string with the message server , Application server,.

SAP recommends the Message server of SAP instance rather than the Application server of SAP instance, Can anybody tell me the background functionality of both the connection strings.

Thanks,

Suresh Bavisetti.

Hello,

The benefit of using the message server in the connect string is that the Process Server connection is not fixed on one server. In case of downtime the connection can fail over. Also since CPS is using a configurable connection pool to the SAP system these connections will be spread over the system. The advantage is that not all these dialog processes will end up at the same application server.

So functionally there is no difference, for CPS it does not matter if all connections end up at the same application server or that the messages server routes the connection to the correct server. But for the same reason SAP recommends to connect through messages servers, it is useful for CPS as well.
