22 DBFS Access Using OFS

You can access Database File System(DBFS) using Oracle File Server(OFS) process. The centralized server background process model of OFS allows multiple file systems to be mounted and accessed using a limited set of server threads. It allows better resource sharing and a linear scalability with new file server threads created on demand. Both memory and CPU used by these threads are controlled through system wide parameters set in the RDBMS instance.

When the newly created DBFS needs to be accessed across multiple nodes where there are no Oracle Client Installation, OFS can be used to NFS mount the file system

(In the absence of an Oracle Client installation, you can use OFS to mount the newly created DBFS to NFS and use it across multiple nodes.) All file system requests are served by threads in the OFS background process.
