yes this is good advise "Read docs and books and practice..."

but you must do something in production system and feeling some stress.
you must encountered fail,error,crash face to face.
now i am a oracle developer, and i have worked oracle dba ,read, practice but not really system only my home database for 1 years.


i know that if you admin on your home database(example database) you are not junior dba yet.
