When deploying Dataguard, the simplest scenario is that the primary/standby node configuration is identical. However, there are times when deployments can happen on heterogeneous operating systems to allow for minimal downtime or risk of data migration from heterogeneous platforms. It is also a complete solution for users to reduce their investment in disaster preparedness by configuring heterogeneous processing power or a backup system with lower har

Db_unique_name Defines the unique name of the database, because the db_name parameter must be the same for the physical database and must be different for the logical database, so the Db_unique_name parameter is introduced in Oracle 10g to determine each database in the Dataguard configuration, if it is not defined, The db_name parameter value is used by default.
