在centos7安装oracle 19C数据库遇到问题一则：发现图形界面无法调出，报错如下：
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
Can't connect to X11 window server using '192.168.xx.xx:0.0' as the value of the DISPLAY variable.
解决办法：
export ORACLE_HOME=/u01/app/oracle/product/19.3/dbhome_1
export DISPLAY=:0
顺利解决问题。
