Oracle Optimal Flexible
Architecture (OFA)
In accordance with Cary V. Millsap of the Oracle
National Technical Response Team, the OFA process involves the
following three rules:
1. Establish an orderly operating system directory structure in
which any database file can be stored on any disk resource.
* Name all devices that might contain Oracle data in such a manner
that a wild card or similar mechanism can be used to refer to the
collection of devices as a unit.
* Make a directory explicitly for storage of Oracle data at the same
level on each of these devices.
* Beneath the Oracle data directory on each device, make a directory
for each different Oracle database on the system.
* Put a file X (X is any database file) in the directory
/u??/ORACLE/sid/type_desig (or on W2K or NT: C:\oracle\sid\type_desig)
if and only if X is a control file, redo log file, or datafile of
the Oracle database whose DB_NAME is sid. The type_desig specifies
the type of file to be placed in the directory at that location and
is usually data, index, control or redo.
