KillThe KILL command in Linux is used to terminate the run of the specified process (terminate a process) and is a common command for process management under Linux. Typically, terminating a foreground process can use the CTRL + C key, but for a background process to be terminated with the KILL command, we need to use a tool such as ps/pidof/pstree/top to get the process PID, and then use the

I. Challenges posed by large-scale concurrencyIn the past work, I have been faced with 5w per second high concurrent kill function, in this process, the entire web system encountered a lot of problems and challenges. If the web system does not do a targeted optimization, it will easily fall into an abnormal state. We are now going to discuss the ideas and methods of optimization, ha.1.

How to kill a process in Linux-general Linux technology-Linux programming and kernel information. For details, refer to the following section. The safest way to kill a process is to simply use the kill command without a modifier or a flag.
First, use the ps-ef command to determine the PID of the process to be killed, and then enter the following command:

Today encountered a problem, there is a table can not operate, it is likely to be locked, the first thought is kill session, so executed the following script to find out which session has a problem:
To see if a table is locked
SELECT/*+ rule*/
a.sid, B.owner, object_name, object_type from
v$lock A, all_objects b
WHERE type = ' TM '
and a.id1 = b.object_id;
According to the SID queried above, find the corresponding serial#:SELECT sid,seri
1. High Concurrency Optimization analysis
about concurrency
Concurrency does not go because when multiple threads access a row of data at the same time, a transaction is generated so that a write lock is generated, and every time a thread that acquires a transaction releases the lock, another queuing thread gets the write lock, and QPS (query per second) and transaction execution times are closely related. The shorter the transaction execution time, the higher the concurrency, which is why the
In Linux, how does one kill a process ?, Linuxkill
Linux Command lines are used to stop all required tools for running processes.
Imagine: You opened a program (probably from your desktop menu or command line) and started to use it. I didn't expect the program to be locked, stopped, or unexpectedly crashed. You try to run the program again, but it says the original process is not completely closed.
What should you do? You want to end the process. But

Second-kill systems often avoid users accessing the URL of a single page (avoid using reptiles to create unfairness). All the developers who need to animate the URL, even if the second kills the system, are not aware of the URL at the start of the second kill. The solution is to return a random number generated by the server side in the interface that gets the second ki
