Hi,
I am trying to install oracle client in one of the AWS EC2 instance ip:10.60.30.30 and facing the issue for Xhost + and Xclock though the packages of the xorg,xclock is installed and up to date.
Here are the steps i followed
--> X11 forwarding to yes in /etc/ssh/sshd_config
--> X11 forwarding enabling from putty/mobaxterm
--> turning on Xming
--> Set DISPLAY=10.60.30.30:0.0; export DISPLAY
Still i face unable to open display issue for Xhost + and Xclock command.
and also i face java exception below when i run ./runinstaller script as oracle user, let me know if it requires any ticket for the same.
[oracle@plb-tfb-dig-w2a-a database]$ ./runInstaller
