Oracle Database Discussions

Hi Friends,

While installing oracle *11g R2 on Linux (Red Hat) 5* I'm facing some issues related to DISPLAY setting leading to some Java related exception during launching 'runInstaller'. Please check below.
I'd faced related issues before as well but after setting DISPLAY variable before (OUI) installation start always prevent such issues to occur, tried same steps this time as well but 'no luck'.

[oracle@localhost database]$ ./runInstaller

>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<

Some requirement checks failed. You must fulfill these requirements before

continuing with the installation,

Please Help.
