Establishing an RFC connection to an R/2 System in an SNI environment is similar to an SAP system, except that the SAP gateway must run on a BS 2000 host.
Therefore, the following sections contain descriptions on establishing RFC connections to R/2 Systems in IBM environments.
Caution
A sideinfo file for the SAP gateway is always required.
The RFC client program can work
with a local sideinfo file (see Programming Example of Working With Local sideinfo File)
without any local sideinfo file (see Programming Example of Working Without Local sideinfo File)
with the saprfc.ini file (see Programming Example of Working With saprfc.ini File)
Note
The following sections describe only how to establish an RFC connection to R/2 Systems with ConnArgv. For information about how to establish an RFC connection to R/2 Systems in the subroutine RfcConnect, see 'srfctest.c' in the RFC SDK.
