谢谢阅读！
今天我有一个非常奇怪的问题。
因为我的docker应用刚刚坏了。.我从未接触过任何文件，只需执行sqlplus，使用它，然后关闭主机操作系统即可。
所以我试图解决这个问题。这是一个错误。
[oracle@7e421c70357d ~]$ lsnrctl status

Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
[oracle@7e421c70357d ~]$
因此，我会尽一切可能检查。
ORACLE_HOME是正确的。ORACLE_HOME是/u01/app/oracle/product/12.1.0/dbhome_1。而且有很多文件和目录，所以很正确。检查两次。
而且我意识到
sqlplus中没有ORACLE_HOME文件夹。我认为sqlplus消失了，完全不见了..
我不知道为什么会这样，没有任何线索。
编辑..
我用谷歌搜索了有关我的问题的所有信息，然后我明白了。

任何人都有解决此问题的想法，请帮助我。
最佳答案
使用此命令查找sqlplus。 sqlplus是一个二进制命令，它始终位于../bin目录中
$哪个sqlplus
通常默认情况下，它们位于以下目录中：
〜/ app / oracle / product / your_db_version / dbhome_1 / bin / sqlplus
转到该目录，并确保它具有可执行权限，其中包含以下内容：
$ cd〜/ app / oracle / product / your_db_version / dbhome_1 / bin /
$ ls -la sqlplus
-rwxr-x--x。 1 oracle mygroup 9479 2015年3月16日sqlplus
运行此命令以确保：
$ sudo chmod 755 sqlplus
类似于'sudo chmod u = rwx，go = rx'
使用此命令检查您的环境设置。
$ echo路径
确保你有这样的东西
/ home / oracle / bin：/ home / oracle / app / oracle / product / your_db_version / dbhome_1 / bin
如果未列出它们，请将它们添加到您的环境中。
$ sudo vi〜/ .bashrc
要么
$ sudo vi / etc / profile
我希望这会有所帮助。祝好运！
