Executing Unix Application from a Windows 2003 server via RFC

Hi,

Got an interesting situation. We're in the process of migrating one of our production R/3 instances (version 4.6c) from a legacy RS-6000-AIX-Informix platform over to Intel-Windows-SQLServer. As part of our discovery process we found in interface that calls a C++ module through a RFC which in turn calls an AS400 to query data and return it to the calling program. This interface is scheduled to be replaced later this year but we have a need to keep it in place for the migration.

We have a source listing for the C++ program but we are not sure if we have all of the necessary libraries so recompiling the program on the windows side may be a bit dicey. One option we are weighing is installing Windows Services for Unix on the new server and configuring the RFC to point to mount point where the C++ is located on the RS-6000. On paper this seems like a viable option, but we wanted to see if anyone had any experience with this or may have an alternative approach to accessing a Unix based C++ module from a Windows based platform via a RFC.

Thanks for listening.
