Oracle Database Discussions

If you have JAVA_HOME or other Java related environment variables set try to unset them for the installation.
The installer uses its own Java from the installer package.

Hi,

for me it is not easy to say what went wrong. What is clear ist that something with the environment is not ok. With oraToolKit however you get a clean environment which will certainly work. Visit:

I have solve this by issued "xhost + " command used root user.
I don't understand why it have any relation with that!

Thanks to everyone!

I am getting the same exception. I tried using xhost_+ but it's still not working for me.
Again, here is the error that I'm receiving when trying to install Oracle 11g:

Thanks in advance for the help!!
Also, this is all very new to me. So if you could provide a step-by-step answer I would really appreciate it.

This worked for me. Hope it helps others as well:
Open a new terminal, change the user to Oracle

Open an xterm session Disable the access control using check if this works If it does, you are ready to run the installer.

See if this helps.
