Hi
We have 2 machines running Red Hat Enterprise Linux Server release 7.7 (Maipo)
We are trying to install 12cR2
We installed the following packages
yum install xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps -y
yum install xhost
Oracle user is created as below
~/staging/database$ id oracle
uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba),16777216(domain users),16777217(e1_users),16777218(sales_branches-rw)
We are able to pull up xclock with no issues
~/staging/database$ xhost +
access control disabled, clients can connect from any host
:~/staging/database$ xclock
Warning: Missing charsets in String to FontSet conversion

But every time we try to run the installer. we keep getting the following..
oracle@tpcq2atgdb01:~/staging/database$ ./runInstaller
Starting Oracle Universal Installer...

We tried setting the DISPLAY as below.. yet still the same error
oracle:~/staging/database$ who
oracle pts/1 2020-01-20 14:50 (10.202.41.13)
oracle:~/staging/database$ echo $TERM
xterm
oracle:~/staging/database$ export DISPLAY=10.202.41.13.0.0
oracle:~/staging/database$ echo $DISPLAY
10.202.41.13.0.0
Can someone please help us as to how to fix this?
We are using MobaXterm and we tried putty as well as the SSH client but getting same error
Thanks
