About Viewing Port Numbers and Access URLs
In most cases, the port number of an Oracle Database component is displayed in the tool used to configure the port.
In addition, ports for some Oracle Database applications are listed
in the portlist.ini
file. This file is located in
the $ORACLE_HOME/install
directory.
If you change a port number after installation, that port number
is not updated in the portlist.ini
file. For this
reason, the portlist.ini
file is an accurate record
of ports configured at the time of installation.
