Re: TCP Ports for listener

The official port for Oracle is 1521. When sqlnet 2 came into existence 1526 was promoted to make sure net 1 and net 2 coexisted. With net8 into existence the story repeats...
Note: If you have defined two ports in listener.ora, it will use the first one. So if you defined both 1521 and 1526 and have 1521 as first in rank, 1526 will not be used. This means clients with 1526 only, can NOT connect. Unless you are using two sqlnet products at the same time, you should use only one port.
