Some startup options such as single - user mode and minimal configuration mode are principally used during troubleshooting . starting the server for troubleshooting with the 某些启动选项(如单用户模式选项和最低配置模式选项)主要在故障排除过程中使用。
If other users are connected to the database at the time that you set the database to single - user mode , their connections to the database will be closed without warning 如果其他用户在您将数据库设置为单用户模式时连接到了数据库,则他们与数据库的连接将被关闭,且不发出警告。
If this fails , put the database in single - user mode by using the alter database statement and trying drop xml schema collection again . if the xml schema collection exists in 如果使用该命令失败,则请使用alter database语句将数据库置于单用户模式,然后再次尝试drop xml schema collection命令。
When you call the xml schema namespace , you can try to retrieve a single xml schema namespace , you can try the call when the system load is lighter , or you can try the call in single - user mode 当调用xml _ schema _ namespace时,您可以尝试检索单个xml架构命名空间,或者您也可以在系统负荷更少时尝试调用,或者您还可以在单用户模式下尝试调用。
For example , to run a sql server instance in single - user mode , it may be necessary to run a clustered instance of sql server as a stand - alone instance from a command prompt instead of starting sql server through mscs 例如,若要以单用户模式运行sql server实例,则有必要从命令提示符将sql server群集实例作为独立实例运行,而不是通过mscs启动sql server 。
On the other hand , a properly configured ups can alert the system of the power outage and send telinit init the sigpwr signal , which will cause init to bring the system into single - user mode or shut the system down altogether , depending on how it s configured 另一方面,正确配置的ups可以提醒系统断电情况,并向telinit / init发送sigpwr信号,这会使init根据其配置情况将系统切换到单用户方式或者完全关闭系统。
Init level 0 is when the system is totally brought down and ready for power to be turned off . init level 1 is single - user mode without any network activity . init levels 2 and 3 are commonly used to run multi - user mode with network activity , and the state in which most machines run 级别0表示系统完全卸载可以关断电源;级别1则表示没有网络支持的单用户模式;级别2和3一般用作网络支持的多用户模式,也就是多数机器的运行模式。
Linux can be in several modes of operation : single - user mode , single - user with networking , multi - user mode , multi - user starting in x , etc . this section will explain the concept of a runlevel , what runlevels are available in slackware , and what they re called Linux可以有几种操作方式:单用户方式、单用户联网方式、多用户方式、始于x窗口的多用户方式,等等。这部分将要说明运行级别的概念、 slackware上有哪些运行级别,已经它们被叫作什么。
