I tried to install Oracle Database on Windows Subsystem for LINUX and when i tried to execute command ./runInstaller following error occured

ERROR: Unable to verify the graphical display setup. This application requires X display. 
Make sure that xdpyinfo exist under PATH variable.

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Can you help me to solve this error? Can we install Oracle Database on Windows Subsystem for LINUX? Screenshot of the error is here

    Do you have an X11 display? – ctrl-alt-delor Mar 29 '20 at 19:48
  • Oracle lists supported platforms on its website. You're unlikely to find WSL as a supported platform. – Thomas Dickey Mar 29 '20 at 21:25
  • Actually I'm new to LINUX environment and I'm not sure whether I have X11 display or not. Can you please help to setup X11 display? – bhanuvinayes Apr 6 '20 at 0:23
  • @bhanuvinayes That would be another question. Also note it is Gnu/Linux not Linux. Linux is the kernel (like the NT kernel is part of Windows 10), Gnu/Linux is the OS. Using the wrong name causes confusion e.g. WSL1 had no Linux: it was Gnu+Linux - Linux. – ctrl-alt-delor Apr 6 '20 at 9:55

WSL does not come with, or install an X Window server, by default.

You can, however, install a 3rd party X Window server such as xming or vcxsrv, both of which I have successfully used with WSL Ubuntu.

    I have just remembered a similar problem setting us oracle on a Gnu/Linux server. The person doing it screamed why do I need a display system to run a database? I had a look, and we decided to install a dump X11-server. Not connected to a physical. I can remember what, there are X11-vnc servers. But I think what we used was even lighter, and incapable of doing anything display like, but did provide the services that oracle needed. I would do a search (but not mention WSL). – ctrl-alt-delor Apr 6 '20 at 10:20
