scsa/create_daemon/exe_file is a SAP Parameter attribute which is used to control program to allocate SCSA information. This is available within R/3 SAP systems depending on the version and release level.
Below is the standard documentation available and a few details of the attributes values .
The SCSA is a shared memory area that is used by basis components such
as system log, trace, and so on. Depending on the operating system, this
area is created either as a standalone shared memory area, or as area
no. 5 on the SAP IPC interface. The creation of a standalone area can be
performed either by each SAP program, or by the standalone program
'sapmscsa'.
