FUSE Linux kernel module for DBFS

I started to play around with DBFS (Database Filesystem), a new interesting feature in Oracle 11.2.

There are some excellent guides on how to set it up:

http://blog.ronnyegner-consulting.de/2009/10/08/the-oracle-database-file-system-dbfs/

But both of them had one "not very clean" part in them - compiling FUSE kernel driver from source. Actually this is not necessary and there are precompiled FUSE rpm packages available:

After RPM package is installed, you need to add the OS user who will mount the filesystem (for example oracle) to OS group fuse.

usermod -a -G fuse oracle
