In a homogenous SAP system distributed across multiple hosts, all files and executables from the physically shared directories under /<SAP System Mount Verzeichnis>/<SAP System ID> (UNIX) or \usr\sap (Windows) are distributed across the remaining instances by sapcpe by default.

“Homogeneous” means that the host computers on which the various SAP instances run all have the same UNIX or Windows operating system. In a heterogeneous SAP system made up of instances running on different UNIX operating systems, or running on UNIX and Windows, the aforementioned does apply universally since the since the various platforms cannot use their executables in common. In the standard installation of a homogenous UNIX or Windows SAP system, the executables are installed in such a way that automatic synchronization of all executables takes place.
