I installed oracle19c on server 10.113.103.146,why 1521 port access many other port on the same server ,and show TIME_WAIT status,log is:

any help? thanks a lot
Solution 1:[1]
Port 1521 is the server port to which the connection is made. It will always be the same. The other ports are the client-side ports, which are randomly assigned, per connection.
TIME_WAIT status indicates that the connection has been closed by the local host (wherever you are running netstat) but is waiting for any remaining packets to come in before completely terminating. These will time out and disappear within a few minutes. See here: http://manpages.ubuntu.com/manpages/jammy/en/man8/netstat.8.html
TIME_WAIT
The socket is waiting after close to handle packets still in the network.
