You are configuring an OBIEE 11g cluster across multiple exalytic machines and you are considering using an existing Oracle Database File System (DBFS) mount for shared files (specifically for the Oracle BI Presentation Server catalog).

Is DBFS supported for shared storage?

What is the Oracle Database File System (DBFS)?

The Oracle Database File System (DBFS) creates a standard file system interface on top of files and directories that are stored in database tables. DBFS is similar to NFS in that it provides a shared network file system that looks like a local file system. Like NFS, there is a server component and a client component.

In DBFS, the server is the Oracle Database. Files are stored as SecureFiles LOBs in a database table. A set of PL/SQL procedures implement the file system access primitives such as create, open, read, write, and list directory. The implementation of the file system in the database is called the DBFS Content Store. The DBFS Content Store allows each database user to create one or more file systems that can be mounted by clients. Each file system has its own dedicated tables that hold the file system content.
