Lesson 1
New backup strategies
A backup strategy is only as effective as the utilities available to the user.
The table in this sidebar compares the new backup utilities and features of Oracle8i with those of Oracle8.
The new recovery features within Oracle8i allow you to:
The table in this sidebar compares the new backup utilities and features of Oracle8i with those of Oracle8.
The new recovery features within Oracle8i allow you to:
- Save the archive redo log files within up to five locations. This can be set using a parameter within the init.ora file. Engage multiple archival processes during the instance startup, providing better performance for instance recovery.
- Significantly increase the performance of the standby database. Within Oracle8i, the archive log files can be automatically sent across to the remote standby database, where they are automatically verified and applied to the database.
- Create a read-only database. This feature is useful in a standby database as this database can be used for executing large queries and reports, without affecting the performance of the production database.
- More efficiently suspend the database for backup purposes.
- Increase the performance of check pointing and recovery of dead and parallel transactions, using Fast-Start Fault Recovery, another new feature.
These are some of the most useful features, which we will learn in greater detail, within this module.
When you have completed this module, you will be able to:
