Solving method L Exchange Technology: a part of the temporarily unable to run the process (blocking the process) to the external memory (only the program and data, the PCB does not change out), to make room for space, can invoke a new process to execute. • Virtual Storage technology: Each process can only lo

the CPU for a single process can be viewed as normal, but the CPU load on the entire system may be abnormal. Through the script to the system CPU load constantly monitoring, can be in the abnormal time to send alarms, to facilitate maintenance personnel timely treatment, prevention of accidents. The following function can detect

parallel execution on multiple processors. When a process is not introduced, only two programs that belong to one application can be executed sequentially. By introducing a process to create a process for multiple programs in memory, they can execute concurrently, greatly improving system resource utilization and

grep uses the basic regular expression syntax, the extended regular expression has a more complete expression specification than the basic regular expression. View the number of running process names Sometimes we may need to get the number of processes started on the server. The following function is to check the number of processes running, for example, the process name is CFTestApp. The Code is as follo
