linux中执行dbca提示command not found，由于oracle软件是安装成功，则检查oracle用户的环境变量文件.bash_profile ，发现环境变量没有修改，修改后，dbca能调出界面。具体如下：

[oracle@stxrhel7 ~]$ dbca bash: dbca: command not found... [oracle@stxrhel7 ~]$ xclock Warning: Missing charsets in String to FontSet conversion [oracle@stxrhel7 ~]$ cat .bash_profile # .bash_profile

# Get the aliases and functions if [ -f ~/.bashrc ]; then ?? ?. ~/.bashrc fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH [oracle@stxrhel7 ~]$ cp .bash_profile .bash_profilebak20220208 [oracle@stxrhel7 ~]$ vi .bash_profile [oracle@stxrhel7 ~]$ source .bash_profile [oracle@stxrhel7 ~]$ dbca ^C[oracle@stxrhel7 ~]$? [oracle@stxrhel7 ~]$ cat .bash_profile # .bash_profile

# Get the aliases and functions if [ -f ~/.bashrc ]; then ?? ?. ~/.bashrc fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
