This disclosure provides an energy storage apparatus, an energy storage apparatus control method, and a photovoltaic system. The energy storage apparatus includes: a plurality of battery clusters, a plurality of conversion units, a start unit, and a controller. The controller includes a plurality of control units. The start unit is configured to: after receiving a start signal, control a control switch in at least one battery cluster to close, to start a control unit corresponding to the battery cluster. The control unit is configured to: determine, based on a state of the control switch in the battery cluster, whether a black start mode is on; and when determining that the black start mode is on, control a DC-DC converter in the corresponding conversion unit to release electric energy stored in a battery pack in the corresponding battery cluster, to energize a direct current bus.

This application provides a method and an apparatus for adjusting a memory configuration parameter. The method includes: obtaining a plurality of pieces of resource pressure, where the plurality of pieces of resource pressure are used to indicate a plurality of requirements for memory compression; and adjusting a memory configuration parameter based on the plurality of pieces of resource pressure, where there is a preset correspondence between the memory configuration parameter and each of the plurality of pieces of resource pressure. The resource pressure is, for example, processor pressure, I/O pressure, memory reclaim pressure, or memory swap space pressure. Memory compression requirements corresponding to different types of resource pressure are different. In the memory adjustment method provided in this application, a plurality of types of information are comprehensively considered, so that system performance can be optimized, and a memory management effect can be improved.

Method and apparatus for adjusting memory configuration parameter

A standard operating procedure (SOP) file generating system () includes a drawing selection module (), an information reading module (), a data determining module (), a machining type determining data module (), and a file generating module (). The drawing selection module selects an engineering drawing. The information reading module reads product information and machining data of the engineering drawing. The data determining module determines whether the machining data accords with machining requirement. The machining type determining module determines a machining type. The file generating module generates an SOP file.
