Hello viewers, welcome to the Step-by-Step Oracle Data Guard series and in this Part-6, we are going to talk about standby database modes.

Note: While the database is converted to Snapshot Standby mode, it will not receive redo data from the primary database and cannot provide disaster protection. Oracle recommends that there be at least two physical standby databases participating in the configuration so that the primary database is always protected.

Oracle data guard is an indispensable part of oracle's high availability solutions. In a real world scenario the Primary and Physical standby databases reside on geographically different locations or different data centers to make sure that even if one region goes completely down, your database is still available and intact. In this tutorial and the series I am covering various topics on oracle Data Guard, like architecture, implementation, administration, management, monitoring etc. Each of these topics may need one or more tutorials to cover it completely. I assume you are already an oracle dba or familiar with at least the basics of oracle database architecture. I will keep everything simple so there won't be any difficulty in understanding the concepts even if you are a beginner.
I am using a virtual environment for demonstration purpose.
