Database 10g: Backup, Recovery and Server Tuning

Course Overview

Oracle Database 10 g includes an increased range of features to ensure optimal performance plus protection and recovery from failure. Those responsible for the integrity and availability of Oracle data must have in-depth knowledge to make the best use of Oracle Database 10 g capabilities.

In this course, you apply techniques to solve a range of issues, including media and site failures, invalid user input, lock contention, and poor memory and storage allocation.

Audience

This course is essential for those interested in safeguarding Oracle 10 g databases. Knowledge of database administration at the level of Course 594, " Oracle Database 10 g Administration ", is assumed.

Skills Gained

• Deploy backup and recovery strategies to safeguard Oracle 10 g databases
• Perform recovery operations to maintain consistent and available data
• Failover to hot standby databases for high availability
• Exploit automated backup and recovery techniques with Recovery Manager
• Implement flashback and logmining to rollback user and logical errors
• Tune the Oracle 10 g server by controlling memory allocation, disk I/O and locking/latch contention
