linux lsnrctl is not an internal command. Solution: 1. After logging in with the root user, execute the "su oracle" command; 2. Using the oracle user, the configuration parameter is "export PATH=/home/oracle/app /oracle/product/11.2.0/dbhome_1/bin:$PATH export ORACLE_HOME=/home/oracle/...".
The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.
linux What should I do if lsnrctl is not an internal command? The lsnrctl start command cannot be found?
The command cannot be found. It must be that the environment variables are not configured correctly, or the database is not closed properly. .
My operation:
Under normal circumstances, after logging in as the root user, execute the su oracle command to bring the environment variables directly.
If you haven’t checked the environment variables yet For parameters, use the oracle user to configure the following three parameters and configure the correct path.
export PATH=/home/oracle/app/oracle/product/11.2.0/dbhome_1/bin:$PATH export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=orcl
Use the oracle user to temporarily configure these three environment variables, and you can start monitoring normally with lsnrctl start.
$ sqlplus /nolog //登录sqlplus SQL> connect /as sysdba //连接oracle SQL> startup //起动数据库
That’s it!

linux设备节点是应用程序和设备驱动程序沟通的一个桥梁;设备节点被创建在“/dev”,是连接内核与用户层的枢纽,相当于硬盘的inode一样的东西,记录了硬件设备的位置和信息。设备节点使用户可以与内核进行硬件的沟通,读写设备以及其他的操作。

linux lsnrctl 不是内部命令的解决办法:1、在使用root用户登录后,执行“su oracle”命令;2、使用oracle用户,配置参数为“export PATH=/home/oracle/app/oracle/product/11.2.0/dbhome_1/bin:$PATH export ORACLE_HOME=/home/oracle/...”即可。

端口映射又称端口转发,是指将外部主机的IP地址的端口映射到Intranet中的一台计算机,当用户访问外网IP的这个端口时,服务器自动将请求映射到对应局域网内部的机器上;可以通过使用动态或固定的公共网络IP路由ADSL宽带路由器来实现。

在linux中,交叉编译是指在一个平台上生成另一个平台上的可执行代码,即编译源代码的平台和执行源代码编译后程序的平台是两个不同的平台。使用交叉编译的原因:1、目标系统没有能力在其上进行本地编译;2、有能力进行源代码编译的平台与目标平台不同。

在linux中,eof是自定义终止符,是“END Of File”的缩写;因为是自定义的终止符,所以eof就不是固定的,可以随意的设置别名,linux中按“ctrl+d”就代表eof,eof一般会配合cat命令用于多行文本输出,指文件末尾。

linux查询mac地址的方法:1、打开系统,在桌面中点击鼠标右键,选择“打开终端”;2、在终端中,执行“ifconfig”命令,查看输出结果,在输出信息第四行中紧跟“ether”单词后的字符串就是mac地址。

在linux中,可以利用“rpm -qa pcre”命令判断pcre是否安装;rpm命令专门用于管理各项套件,使用该命令后,若结果中出现pcre的版本信息,则表示pcre已经安装,若没有出现版本信息,则表示没有安装pcre。
