Control parameters in the POSIX information file SYSSSI.POSIX-BC.<version> determine the size of the system tables. This is used to control the resources which the system and the user can request.
Each control parameter is assigned a default value, a minimum value and a maximum value. The default values are selected so that the POSIX subsystem can operate in any environment without burdening the overall system by making excessive use of resources. Sie können diese Steuerparameter jedoch bei Bedarf an die Gegebenheiten Ihres Systems anpassen.
The POSIX information file is only evaluated when the POSIX subsystem is started up; changes therefore only become effective after the next startup. However, some control parameters can also be modified during ongoing operation using the usp command, see the manual "POSIX Commands" [1].
