About the Optimal Flexible Architecture Standard Oracle Optimal Flexible Architecture (OFA) rules help you to organize database soft‐ ware and configure databases to allow multiple databases, of different versions, owned by different users to coexist. In earlier Oracle Database releases, the OFA rules provided optimal system perform‐ ance by isolating fragmentation and minimizing contention. In current releases, OFA rules provide consistency in database management and support, and simplifies ex‐ panding or adding databases, or adding additional hardware. By default, Oracle Universal Installer places Oracle Database components in directory locations and with permissions in compliance with OFA rules. Oracle recommends that you configure all Oracle components on the installation media in accordance with OFA guidelines. Oracle recommends that you accept the OFA default. Following OFA rules is especial‐ ly of value if the database is large, or if you plan to have multiple databases. C-1
