| This hands-on course will teach you how to exploit the capabilities of Data Guard (back-ported to earlier releases when necessary) with insight into how best to use the various features. The course provides in-depth coverage of Data Guard for all releases: the current release is used for exercises and demonstrations, and the content back-ported as necessary for previous releases.
There is emphasis on Data Guard being more than a zero data loss solution. For example, it can give you performance (Logical Standby), development and testing systems (Snapshot Standby), and is a vital part of distributed Oracle database environments. As with all SkillBuilders courses, this class (if conducted at your company facilities) is highly customizable to your specific training requirements. This course is designed for database administrators, though IT Management will also find the content valuable for planning and infrastructure design purposes. Technical RequirementsNothing is required for labs (workshops). SkillBuilders will provide everything you need for all hands-on labs. Modest PC or Mac specs (including a microphone) are required to connect to the online class. Detailed specs can be found here. Also, we recommend using two monitors for this class. This provides the student one monitor to view the instructor screen and another for lab work. |
