netstat port display result and listener.log port number is not consistant
I have switched my port number from 1522 to 1521 but I can still see there are a lot of connections to 1522 from application server ( using netstat -o -n -a command) but I cannot see any connections to 1522 in listener log file. Why is that? PMON register all services in 1521 by default, so I switch all connections in connection string or tnsnames to use 1521 for my applications. why 1522 is still in use from netstat command?
Thanks for your input!
