The principle of Android memory management--process managementAndroid takes a different process management strategy from Linux , and unlike Linux, which ends the process after the process activity has stopped, Android keeps the pr

Supervisor IntroductionFirst, introduce supervisor. Supervisor (http://supervisord.org/) is a client/server service developed with Python and is a process management tool under the Linux/unix system that does not support Windows systems. It is easy to listen, start, stop, restart one or more processes. With supervisor management

Zookeeper process control is the most basic function in process management. It is used to create a new process, terminate a completed process, or terminate a process that is unable to run due to an event. It can also be responsibl

Differences between scheduled tasks, process management, and disk management processes and programs in Linux learning Notes: 1. A program is a static concept, which is stored as a software resource for a long time; A process is the execution process of a program. It is a dyn

Introduction: This is a unix/linux system Management Automation series, mainly about how to achieve automated monitoring process status and performance and timely notify the system administrator. Process monitoring is a very important part of unix/linux system management. It can monitor the

namespace, and the network namespace. Namespaces simply provide an abstraction of a global resource, placing resources in different containers (different namespaces), and each container being isolated from one another. Namespaces have hierarchical relationships, such as the PID namespace, and Figure 1 is a hierarchical diagram of namespaces.Figure 1 Hierarchical relationship of namespacesIn four namespaces, a parent namespace derives two child namespaces, one of which is derived from a child na

management, namely the creation state and the terminating state.① Create a state, creating a process typically takes two steps. First, a common PCB for a new process, and fill in the necessary management information, second, the process into a ready state and inserted into

pointer. If statloc is not a null pointer, the termination status of the terminated process is stored in the memory unit pointed to by the pointer. If you do not care about the termination status, you can set the parameter to null. When a process calls wait, the caller is blocked until a sub-process is terminated. If no sub-
