Getting this error in log.xml,
<txt>TNS-12546: TNS:permission denied
TNS-12560: TNS:protocol adapter error
TNS-00516: Permission denied
Reason:
The sqlnet.ora file is configured for TCP.VALIDNODE_CHECKING with a TPC.INVITED_NODES list that does not include the ip address on which the listener is trying to start.
The "permission denied" message is the result of the SQL*Net layer refusing a connection from the listener.
Solution:
Either unset TCP.VALIDNODE_CHECKING in the server side sqlnet.ora file or configure the TCP.INVITED_NODES list to include the ip address or hostname of the server where the listener is failing to start.
