Non-ASM Environment
In a non-ASM environment on a Unix server, at least three file systems on separate physical
devices are required to implement OFA recommendations. Starting at the top, the recommended
format for a mount point is /
, where can be one or
several letters and is either two or three digits. For example, on one system we
may have mount points /u01, /u02, /u03, and /u04, with room to expand to an additional 96
mount points without changing the file-naming convention. Figure 3-5 shows a typical Unix file
system layout with an OFA-compliant Oracle directory structure.
There are two instances on this server: an ASM instance to manage disk groups and a standard
RDBMS instance (dw).
Software Executables The software executables for each distinct product name reside in the
directory ///, where
and are defined previously, implies the type of files installed in
this directory, and is the name of the user that owns and installs
the files in this directory. For example, /u01/app/oracle would contain application-related files
(executables) installed by the user oracle on the server. The directory /u01/app/apache would
contain the executables for the middleware web server installed from a previous version of Oracle.
As of Oracle 10g, the OFA standard makes it easy for the DBA to install multiple versions of
the database and client software within the same high-level directory.
