Configuring Active Data Guard Far Sync Using a Terminal Standby Database as Alternate Log Archive Destination in Data Guard Broker (Doc ID 1918316.1)

Last updated on FEBRUARY 03, 2019

Applies to:

Purpose

 Use of the terminal standby as an alternate destination in a Far Sync configuration requires accepting that, provided the terminal standby database is not within acceptable sync network range, the configuration will run in asynchronous mode during the entire period required to resolve the Far Sync instance outage.  The advantage of this approach is that it requires no additional hardware or software to deploy or manage.  Applications that can tolerate increased data loss potential during a Far Sync instance outage and where low cost is the main consideration may be best served by configuring the terminal standby as an alternate location using ASYNC redo transport.
