Oracle Default Port Numbers
As TCP/IP has become the de facto standard for open systems networks, it is useful to know what port numbers Oracle commonly associates with its services.
Port Numbers
Ports are a TCP feature, although the same port is used for UDP where possible. They generally specify the point of contact for a particular service. This contact port is sometimes referred to as the "well-known port".
The port numbers are divided into three ranges: Well Known Ports, Registered Ports, and Dynamic and/or Private Ports.
- Well Known Ports range from 0 through 1023.
- Registered Ports range from 1024 through 49151
- Dynamic and/or Private Ports range from 49152 through 65535
Well-Known Port Numbers
The Well Known Ports are controlled and assigned by the Internet Assigned Numbers Authority (IANA). Generally, Well Known ports can only be used by system (e.g. root) processes or by programs running as root.
Oracle Well-Known Ports
There are a number of Well Known ports that have been set aside for Oracle by the IANA. Some have never been documented or recommended. Refer to the table below, Oracle Default Port Numbers for the default values provided by each application.
