这个解释篇幅有点长

The Optimal Flexible Architecture standard helps you to organize database software and configure databases to allow multiple databases, of different versions, owned by different users to coexist. Optimal Flexible Architecture assists in identification ofORACLE_BASE with its Automatic Diagnostic Repository (ADR) diagnostic data to properly collect incidents.

All Oracle components on the installation media are compliant with Optimal Flexible Architecture. Oracle Universal Installer places Oracle Database components in directory locations, assigning the default permissions that follow Optimal Flexible Architecture guidelines.

Oracle recommends that you use Optimal Flexible Architecture, specially if the database grows in size, or if you plan to have multiple databases.

网络释义

  优化自由结构

Oracle 9i和sql的区别 - Oracle / 基础和管理 SQL.2\MSSQL\DATA，依此类推。 Oracle安装也有一个标准的目录结构，Oracle称之为优化自由结构(Optimal Flexible Architecture, OFA)，OFA的基本理念就是将数据库文件放置在一系列标准化的目录中，使得DBA管理数据库变得更轻松，更容易

其实有简单的解释

Optimal Flexible Architecture (OFA)

A set of file naming and placement guidelines for Oracle software and databases

其实就是一个命名规则，作标识用的。
