METHOD FOR THE COMPUTER-SUPPORTED RESTRICTING OF PERSISTENT MEMORY FOR A CONTAINER-BASED APPLICATION
The invention relates to a method for the computer-supported restricting of persistent memory for a container-based application (AP), wherein a number of container instances (CIN1, CIN2) are assigned to the application (AP), wherein a number of first users (UC1, UC2) are contained in the number of container instances (CIN1, CIN2), wherein a respective first user (UC1, UC2) is a container-specific user in a corresponding container instance (CIN1, CIN2), wherein: - to configure the number of container instances (CIN1, CIN2) a piece of configuration information (CO) is provided that defines, for each first user (UC1, UC2), a storage limit of persistent memory on at least one memory partition of the specified operating system (OS); - during configuration of the number of container instances (CIN1, CIN2) a user assignment (UAS) is defined, according to which another second user (UOS1, UOS2) is assigned to each first user (UC1, UC2) in the specified operating system (OS), which second user is unique across the number of container instances (CIN1, CIN2) and for which the storage limit of the respective first user (UC1, UC2) is valid; - the number of container instances (CIN1, CIN2) are started based on the user assignment (UAS), wherein with the aid of the second user or users (UOS1, UOS2) the storage limit for each first user (UC1, UC2) is adhered to.
The invention relates to a circuit breaker (SG) for protecting an electric low-voltage circuit for an alternating voltage, wherein the level of a differential current of conductors of the low-voltage circuit is ascertained, and if differential current thresholds or differential current time thresholds (DSG1) have been exceeded, a process for preventing the flow of current in the low-voltage circuit is initiated by means of a high-ohmic state of switching elements of an electronic interruption unit in the closed state of separating contacts with a subsequent present current value which falls below a current threshold.
