blocks between RAC instances. The corresponding Service is GCS (Global Cache Service). LMS is an important part of Cache Fusion. The LMS process is the most active background process on RAC, which consumes a lot of CPU. generally, each instance has multiple LMS processes. The default number of LMS processes for each Oracle version varies. The default value for m
As we mentioned earlier, Oracle instances consist of a memory structure and a group of background processes. The important background processes of Oracle include:
· SMON· Pmon· Dbwr· Lgwr· Arch· Ckpt
Next we will introduce the functions of each process one by one.
I. SMONSMON (system monitor)-a system monitoring process

In Linux, if you want to run the process in the background, we usually add to the end of the command. In fact, the command is put into a Job Queue:
./rsync.sh # jobs
However, for processes executed from the top to the backend, the
These two cases should be discussed together, because the real dx background (except dx to gdi) needs to be injected into the game process.There are many ways to inject game processes, such as input method injection, network injection, and registry injection.First, Hook, the API setwindowshookex, Baidu or MSDN used. It is best to check MSDN for details.With a message injection
This article mainly introduces the method of PHP to create a single background process, involving PHP for process start, create, judge, stop and other related operations skills, the need for friends can refer to the next

Oracle background processes are an important part of the Oracle database framework. The following describes various types of Oracle background processes for your reference and use.
Oracle background processes include Database Writer, DBWR, Log Writer, LGWR, System Monitor, and SMON, PMON), Checkpoint Process (CKPT), ar
You can use the following statement to start a PHP background process:
$ Command = "PHP script. php"; $ pid = exec ("nohup $ command>/dev/null 2> 1 Echo $! ");
Nohup indicates that the process is independent of the created user and can run in daemon mode.
If you need to run the background
Oracle RAC background process Introduction
There are more processes in the Oracle RAC database than in a single instance database. These processes are unique to RAC and are set to implement cluster database functions. This article will introduce RAC-specific processes.

different CPU types, the startup process of Windows systems running in different CPU Systems is also slightly different. This article will introduce you to the 32-bit Windows XP Professional installed on the X86 architecture.Basically, the operating system boot process starts after the computer power-on self-check is completed, and this

There are 15 default background processes. 1.master thread (1). 2.IO thread (1) read/write thread (8, default 4) (2) Insert buffer thread (1) (3) Log IO thread (1) 3.lock Monitor Thread (1) 4.error monitor thread (1) 5.purge thread (1) 6.purge Cleaner (flushing) thread (1) 7.

In the use of Jenkins, we encountered a scenario is: After the Web code changes, can be automatically deployed to the test server, we wrote the run.sh script to restart the service, in the use of Jenkins's task to automatically run the scripts found that the service is not up. began to think that it was a run.sh script problem, but the direct execution is not a problem, and then always check the operating environment differences, found that this is no
