Hi
Do define relationship between OS and database is like going to gas station and learn the procedure how to fill Gas in your car and etc.......it is so complected. Anyway, we provide complete management with our
dedicated hosting services and we serve our clients to have a database installed on their machines. Hence, you don't need to worry.
However, if you are very eager to know relationship between DB and OS, then one thing you should keep in mind. It is very important to understand what things are essential to run database smoothly on your machine, and therefore your system should meet some essential requirements such as,
1.Minimum hardware requirements
2.Installation of RPM packages, which are required for DB installation
3.Configuration of Kernel parameters
4.Creating groups and user for DB Installation
5.Installing DB Software and etc.....
