A Unix operating system may paralyze the system after a sudden power failure. At this point, the Unix operating system is not as good as that of Microsoft. In the event of a power failure, the Windows operating system will automatically detect and recover when it is restarted, But Unix will not. We need to manually execute The fsck

As you know, there are times when it is necessary to terminate all Oracle processes (process) or a specified set of Oracle processes. When the database is "locked" and you are unable to enter Server Manager to "gently" terminate the database, you can terminate all Oracle processes with the KILL command in Unix-one of the common uses of the KILL command.When you need to terminate an Oracle instance (instance

In the process of using the UNIX operating system, we often use a variety of problems, such as the system suddenly slowed down, the system is prone to panic or the host of the terminal often appear panic, when we often guess, is hard disk space is too small, or insufficient memory? Is there a bottleneck in I/O, or is there a problem with the core parameters of the system? At this time, we should consider using the system to provide us with the SAR
