tuning outbound RFC (TCP/IP, "registration")
We use RFC from SAP R/3 (Rel 4.6C) to an external application.
The RFC-destination is of type T (TCP/IP) of course, with activation 'registration'. This means that the other application has registered with the gateway process of the SAP-system (sapgw) and said it would be listening for calls.
We are looking for documentation on tuning on the SAP side (we are looking at the other side, too).
I have found documentation for tuning inbound RFC (RFC-calls into SAP R/3 or more generally into the SAP ABAP-stack), but I have not found anything in outbound RFC.
Yet something must be tuned - we notice that the hard way.
Obvious questions are:
1. How can we increase the number of simultaneous connections the SAPGW can handle?
2. If the other application does not respond swiftly, how can we increase the timeout in SAP?
