Use
If you have a distributed homogeneous SAP System, then you can choose how the distributed instances are to access the executable files (programs) of the R/3 System. Here, homogeneous means that the host on which the various SAP instances run, all have the same UNIX operating system.
In a heterogeneous SAP System made up of instances running on different UNIX operating systems, or running on UNIX and NT, the aforementioned does apply universally since the since the various platforms cannot use their executables in common.
Implementation Considerations
In a homogeneous UNIX-SAP System, you can choose between a standard installation (see
Structure of Executables after the Standard Installation) and an Installation of Local Executables with Automatic Adjustment.For more information on the differences, and advantages and disadvantages of both choices see
The Differences Between Central and Local Executables.
