This course provides a hands-on exposition of the Oracle Recovery Manager (RMAN) utility for backup and recovery of Oracle databases and additional capabilities. The course provides in-depth coverage of RMAN, for all releases: the current release is used for exercises and demonstrations, and the content back-ported as necessary for previous releases. This course is designed for database administrators, though IT Management will also find the content valuable for planning and infrastructure design purposes. As with all SkillBuilders courses, this class is highly customizable to your specific training requirements. Technical RequirementsNothing is required for labs (workshops). SkillBuilders will provide everything you need for all hands-on labs. Modest PC or Mac specs are required to connect to the online class. Detailed specs can be found here. Also, we strongly recommend using two monitors for this class.
