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.

I added the following entry in sqlnet.ora :

1.tcp.validnode_checking = yes

tcp.invited_nodes = (172.23.xxx.xxx,10.xxx.xx.xxx)

2.reload the listener successfully

3.try to connect to oracle from localhost it throws error :

ORA-12514 TNS:listener does not currently know of service requested in connect descriptor

4.When I remove the entry from sqlnet.ora and reload the listener once. The change is not reverted .When I reload it multiple times.

My Oracle database connects fine.
