Overview of the SAS RFC Server

The SAS RFC server is part of the SAS/ACCESS Interface to R/3 in a z/OS operating environment. The SAS RFC server is a component of the SAP LIBNAME engine that provides access to the data in SAP Systems. The SAS RFC Server also supports calling ABAP RFC functions. The SAS RFC Server 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.

The SAS RFC server:

• runs independently of SAS as a background process on

  • the SAS host

  • the R/3 host

  • another machine entirely

• can be configured to listen on any TCP/IP port (default 6999).

• can have more than one concurrent instance on a given machine (but each instance must have a unique port number). Each instance can communicate with many SAP Systems.

• can process requests from multiple SAP application servers.

• can support Unicode and non-Unicode SAP Systems.
