Hi,
I am installing Oracle 10G R2 on Fedora 8 machine.
I followed all the steps which are given in http://www.puschitz.com/InstallingOracle10g.shtml

But when I execute ./runInstaller script I am getting below given error.

Please help.

THanks

I tried following thing:

[oracle@neelesh ORACLE]$ ./runInstaller --help

The DISPLAY environment variable should be set to <hostname or IP address>:<screen>, where the <screen> is usually '0.0'.............

So I tried :

# xhost +

but again it gave error:

No protocol specified
xhost: unable to open display ":0"

Please suggest.

I resolved this issue by following way:

1. As root user I run "xhost +" command so access control got disabled
2. Then as "oracle" user I ran same command.

and now I ran ./runInstaller command and it worked.,

In the section on running the runinstall it tells you to set the DISPLAY and the xhost settings. You need to follow all the instructions.
