Parameter
scsa/autocreate
Short text
Create missing SCSA automatically
Parameter Description
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. If an SAP program recognizes that the SCSA is (still) missing, it usually creates it automatically. To break loops if necessary, this can be switched off.
