Installation Environment Preparation Tool
In fact, direct rpm can be installed, it will automatically resolve dependencies including environmental preparation tools, but this is not oracle user home directory, so install a separate environment Preparation Tool

This creates a default database named ORCLCDB and pdb name ORCLPDB1, of course, can not be so created, the traditional way dbca
Advantages and disadvantages
In fact this way and no use, compared to a silent installation also did not appear to be easier to install the database software only, and can not upgrade the database, and can not be used rac, can only be used to install a single-instance database, the entire deployment does not give For example, if the directory space oracle_home customized with your company's disk is inconsistent planning it, but the novice may think this is more simple, the only way to try it to taste, actual production is almost unusable
