OUI (Keys)

Here I have pointed out only the facts that are hard to remember but really important during OUI installation.
 * OUI on Linux, you have to first set the WINDOWS X DISPLAY variable
 * You start OUI by runinstaller.sh command (can use -ignoresysprivs)
 * You start copying oracle binaries to oracle home
 * You start linking binaries to create executable files to run the software.
 * Then you start to work with configuration scripts as super user root.
 * Here you use orainstroot.sh to create inventory and sets the permissions, it creates the oraist.loc file that includes inventory information and software owner name.
 * Then you use root.sh to copy files outside oraclehome and set permissions. It has a file called oratab which includes database info and oraclehome location.
