extraArchivedLogDestIds

Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

In a primary-to-multiple-standby setup, you might apply the following settings.

archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it's necessary. For more information about RESETLOGS, see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide.
