Can anyone help?

Solution 1

If it still doesn't work, double check if you use su - oracle because Using su - oracle will break X screen forwarding or proper display when using Oracle runInstaller.

So you need ssh the host with user oracle.

Solution 2

For RHEL, I did the following and solved this error.

If xclock is not installed, install it as shown below:

yum install xorg-x11-app*

then type xclock, and xclock will be displayed. Now, do this as root:

xhost +dwiba01-I114159.ca.com
su oracle
./runInstaller

Change dwiba01-I114159.ca.com to the domain you are connecting from.

There's no such thing as "Linux 6.1", is that RedHat? What's the java version you have installed (java -version)?

[Admin]

yes i am installing on red hat and java is not installed

[user3209083]

I have installed the java but error is same

[user3209083]

i am running xhost+ and error shows unable to open display ...

The display is either not set or isn't accessible. Confirm that the env. var. DISPLAY is set, echo $DISPLAY.

[user3209083]

DISPLAY=oracle:0.0; export DISPLAY sir this env variable is set as shown in post

[slm]

What is oracle in that statement? The local machine's name or some remote computer you're connecting from?

[user3209083]

this is host name of localhost machine
