X-Server access is denied on host

in Linux 5 comments

Trying to launch GUI wizard of Oracle FMW Infrastructure 12.2.1.3.0 on Linux 7 using jdk-8u211-linux-x64 but receiving the following error:

X-Server access is denied on host

[Fatal Error] DISPLAY variable set incorrectly: :0.0

[Resolution] Verify that your DISPLAY environment variable is set correctly,

and that there is an X11 server on the system. If you are

running the Oracle Installer as a different user or on a different host,

you may need to use the xhost command to ensure that host/user

has permission to write to your display.

Content (required):

  1. Using Mobaxterm client on Windows with X11 forwarding enabled.
  2. Connecting to the linux server as root user and noting the xauth cookie that is being referenced in $DISPLAY.

Howdy, Stranger!
