Oracle8 New Features
Oracle8 has been designed to be able to support more users and bigger databases than Oracle7 by making better use of
resources and to be easier to administer and maintain. It also provides better support for distributed and n-tier
environments and supports a limited set of object oriented features to make the database structure closer to the real
The new features include:
Enhancements for very large databases and on-line transaction processing systems
A Recovery Manager utility to complement Enterprise Manager
Ad hoc enhancements such as password management and index only tables
Object support within the database and object extensions to SQL
Support for the network computing architecture - a multi-tier
architecture that supports standards such as CORBA, ActiveX,
HTTP and Java with each tier extensible through the use of
cartridges. The main benefits are easy maintenance due to the
use of a modular architecture, extensibility and the ability to
integrate legacy systems with new object-oriented applications.
Oracle8 Recovery Manager (RMAN)
This is a new utility designed to automate some of the manual tasks
involved in the backup and recovery of very large databases in
particular. It does this by maintaining a recovery catalogue, which
holds information required for backup and recovery and enables both
the backup and recovery processes to be performed automatically.
The recovery manager can be used to back up the whole database, individual tablespaces or data files, or just changed
blocks. Initially, the database files are backed up on to the disk as a backup set which can then be copied to tape.
The utility can also produce reports to show which data files are in need of a backup and which backup sets contain
archived logs with a specified name and within a specified range.
