Create DBFS File System

create user dbfs identified by dbfs default tablespace users quota unlimited on users;

grant dbfs_role to dbfs;
grant create session to dbfs;
grant create procedure to dbfs;
grant create table ro dbfs;
alter user dbfs default role all;

Create a simple file system

cd $ORACLE_HOME/rdbms/admin
