Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Access via tcp.validnode_checking

May 15, 2015 3:53AM edited Jun 1, 2015 8:09AM in Database Networking (MOSC) 3 commentsAnswered

We have 2 settings in our sqlnet.ora file on the Oracle server

TCP.VALIDNODE_CHECKING=YES

TCP.INVITED_NODES=(hostname1, hostname2, hostname3)

With these settings, I have been informed that if any of the hosts are in the list are not contactable, the Listener will not start.

Is this correct and if so, what can be done to mitigate this issue ?

Thanks

Nick
