Oracle linux is a rebuild of the SERVER operating system from redhat BUT it is optimized to run Oracles Database on SERVERS
it has rather limited LAPTOP support
as in it was NEVER designed for use on laptops and if it runs on the hardware it is just by chance ( mostly)
oracle has there own documentation but i think you have to actually buy the support contract to use it
the redhat docs are open to everyone ( BUT might be a bit different than Oracle)
https://access.redhat.com/documentation
https://access.redhat.com/documentat...ide/index.html
also be aware that the 6 series is a bit older
The CURRENT is RHEL 7.1 or Oracle 7.1
there will be a bit MORE support for newer hardware in the 7.1 OS than in the older 6.7 operating system
BUT!!!
CentOS has better desktop and laptop support than RedHat and Oracle do
for RHEL and OEL you really do need to buy the support contract
