For the purposes of this document, the following fictitious environment is used as an example to describe the procedure:
Database Unique Name: STDB2_GAL,STDB2_INV
Instance Name: STDBY2
Host Names: HOST_1.TEST.NET, HOST_2.TEST.NET
Disk Group Names: +FRA01
Prior to Oracle Database 11g you can see from the Data Guard Broker documentation states the following in regards to the redo archiving destinations in a broker configuration:
On the standby database, the broker registers a special service name db_unique_name_XPT with the standby listeners for redo transport services. On the primary database, the broker extracts the listener address from the LOCAL_LISTENER initialization parameter, and uses the service name db_unique_name_XPT and the value of INSTANCE_NAME to construct the connect descriptor so that redo transport services transmit archived redo log files to the standby apply instance.
How do you change the redo transport network configuration when a Data Guard configuration is in place, from the public network interfaces currently used to a network dedicated to redo transport?
The Scenario in more detail:
Currently we have a listener accepting connections through the public IP/hostnames shown below
