Log: tmp/OraInstatt2l9-O614 e758-UAM/instalt2el9-e614e7-58-HAM.log
No protocol specified
X-Server access is denied on host
(Fatal Error] DISPLAY variable set incorrectly: :O.0
[Resolutionj Verify that your DISPLAY environment variable is set correctly,
and that there is an Xli 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.
Root Cause:
When you run the installation from a remote terminal, or if you use a su command to change users you might receive an error.
This Error occurs if the Display variable is not set, or the user running the installation is not authorized to open an X window.
If you starting your Host or server with Root user and use su command to change from a user with lower-privileged user, such as (Oracle) that is authorized to run the Fusion infra installer but not authorized to open an X window on the display, you will hit this error as X-server Access is denied on Host.
Troubleshooting:
To troubleshoot this issue, run the command echo $DISPLAY to ensure that the display variable is set to the correct host. If the display variable is set correctly then either ensure that you are logged in as the user authorized to open an X window, or run the command xhost + to allow any user to open an X window.
Step By Step Instructions to Fix Issue
Step 1: Make sure you are login to root user and run the command echo $DISPLAY to ensure that the display variable is set to the correct host.
# echo $DISPLAY
:0.0
Step 2: With Root user, run the command xhost + to allow any user to open an X window
#xhost +
access control disabled, client can connect with any host
Step 3: Start Fusion Infrastructure installer again..
