For Oracle 11g2 installation on a server, that has no X11 available you will have to use specific argument for install command:

[code]
runInstaller -silent -responsefile db.rsp
[/code]

db.rsp is an Oracle response file for providing required values for installation, that would be otherwise asked by graphical installer.
NB! Relative path to response file is not supported (like ../../db.rsp).

Here is an example of a response file for Oracle 11g2

[code]

Using this response file you will install Oracle Enterprise edition without creating a database to /opt/oracle using user “oracle” and group “oracle“. You may change user, group and install folder by editing the response file.

NB!
Before running the installer ensure you have created user oracle and added permissions for /opt/oracle folder. Also install Oracle prerequisite packages by running:

[code]
yum install gcc gcc-c++ gcc-c++-devel glibc-devel libgcc libgcc-devel libaio libaio-devel compat-libstdc++-33 libstdc++ libstdc++-devel elfutils-libelf-devel ksh
[/code]
