The SAS RFC Server is
part of
SAS/ACCESS Interface to R/3 in a
z/OS operating environment.
It is a component of the SAP LIBNAME engine and provides access to
the data in SAP systems. It supports calling ABAP RFC functions, and
it uses the TCP/IP protocol for communication with the SAP LIBNAME
engine.
For
more information about the SAP LIBNAME engine, see Overview of the LIBNAME Engine for SAP.Here is important information
to keep in mind about the SAS RFC Server.
-
It runs independently of SAS as
a background process on the SAS host, the R/3 host, and another machine
entirely.
-
You can configure it to listen
on any TCP/IP port (default
6999).
-
You can have more than one concurrent
instance of it on a given machine, but each instance must have a unique
port number. Each instance can communicate with many SAP systems.
-
It can process requests from multiple
SAP application servers.
-
It can support Unicode and non-Unicode
SAP systems.
