Tài liệu Oracle9i Installation Guide phần 3

Oracle Corporation recommends that the Optimal Flexible Architecture (OFA)
standard be implemented when installing and configuring Oracle9i databases. The
OFA standard is a set of configuration guidelines for creating fast, highly available,
and reliable Oracle databases that require little maintenance. An OFA-compliant
database:
■ organizes file systems to allow for easy administration
■ accommodates scalability, such as adding data into existing databases, or
adding users to the system
■ distributes I/O loads across disk drives to prevent performance bottlenecks
caused by multiple read/write commands issued simultaneously to a single
drive
■ distributes applications across more than one drive to safeguard against disk
failure
■ ensures integrity of login home directories when home directories are added,
moved, or deleted by the DBA
■ allows multiple versions of the application software to be used concurrently
