TCP.VALIDNODE_CHECKING and TCP.INVITED_NODES With Oracle's Data Guard? (Doc ID 1968655.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.3 to 12.1.0.2 [Release 11.2 to 12.1]
Information in this document applies to any platform.

Goal

This document explains how the sqlnet.ora file settings for TCP.VALIDNODE_CHECKING and TCP.INVITED_NODES work with Oracle's Data Guard

Adding only the standby database to the TCP.INVITED_NODES parameter on the standby does not impact the operation of Oracle's Data Guard product. I can not TNSping the standby from the primary, I can not connect via telnet to port 1521 nor can I log onto the standby via SQL*Plus from the primary. These attempts get ORA-12537.  Expected Data Guard connections to fail since the hosts are not in the access list.
