Oracle Data GuardChapter 3 - Implementing Standby
Databases
Oracle Net Configuration
For this text, assume that the Oracle Net is
using the tnsnames.ora file for node identification. On the primary
site, the tnsnames.ora file should be configured to include the
service name for each of the standby databases.
The listener.ora file on the primary site does
not require any modification as long as it has a listener for
itself. Similarly, on the standby site the listener file will not
require any change.
Configure the tnsnames.ora file on the standby
site to include the service name for the primary database. This is
required for gap resolution using the “fetch archive log” method. A
sample tnsnames.ora file from the primary and the standby site is
given in the following example.
