The oracle Database File system is a feature that creates a standard file system on top of files and directories stored in database tables. It is similar to NFS and provides a shared network filesystem that looks like a file system .
It has both server and client component.

In DBFS, the database is the server where the files are stored as secure LOB's . A set of PL/SQL procedures implement the file system access primitives like open,create etc.This implementation is termed as DBFS content Repository.

DBFS client component runs on the client machine. On linux, the dbfs_client interfaces with FUSE kernel module to implement a files system mount point that provides transparent access to the files stored in database.

This note provides the flow for the installation of the DBFS
