最优灵活体系结构(Optimal Flexible Architecture,OFA)

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.

最优子结构(optimal substructure)

最优子结构是依赖特定问题和子问题的分割方式而成立的条件.各子问题具有最优解,就能求出整个问题的最优解,此时条件成立. 比如求广州到北京的最短距离,假设这个路径必经过中间的南京,那么先把路径分割为(广州,南京)和(南京,北京).分别求出子路径的最短距离然后再连接,就可以得到广州到北京的最短路径. 因此,寻求最短路径的问题可以利用子路径的最优解获得整个问题的最优解.这样就可以证明,最短路径具有最优子结构. 当然最长递增(LIS) 反之,如果不能利用子问题的最优解获得整个问题的最优解,那么这种问题就不

Oracle的OFA架构

Oracle的最佳灵活体系结构(Optimal Flexible Architecture,简称OFA),是指Oracle软件和数据库文件及文件夹的命名约定和存储位置规则.可以将它作为一组好的习惯,它使用户可以很容易地找到与Oracle数据库相关的文件结构. 使用最佳灵活体系结构,能够简化数据库系统的管理工作,使数据库管理员更加容易地定位文件或添加文件:还可以将Oracle系统的执行文件.管理文件.数据文件分别存储到不同的硬盘上,从而有效地使用用户系统中的所有存储空间.克服某个(些)硬盘存储空间
