最优灵活体系结构(Optimal Flexible Architecture,简称OFA)
OFA其实就是一种Oracle的一种规范,其意义就是用一种统一的给文件和文件夹的规则,和文件存放目录的规则做一个约定。这样,我们不管是安装多个版本的Oracle
Database也好,因为目录规范,命名规范,这样软件不会冲突,方便管理,文件也方便查找。通过遵循OFA的指导,使得整个系统可以更加灵活
Advantages of Multiple Oracle Homes and OFA
When you install Oracle database, you are installing a large application that
your computer can support. Using multiple Oracle homes and Optimal Flexible
Architecture provides many advantages when administering large databases. The
following advantages are important:
- Structured organization of directories and files, and consistent
naming for database files simplify database
administration. - Distribution of I/O across multiple disks prevents performance
bottlenecks caused by multiple read or write commands issued simultaneously to
a single drive. - Distribution of applications across multiple disks safeguards against
database failures. - Login home directories are not at risk when database administrators add,
move, or delete Oracle home directories. - Multiple databases, of different versions, owned by different users can
coexist concurrently. - Software upgrades can be tested in an Oracle
home in a separate directory from the
Oracle home where your production database is located.
