During installation, Oracle Universal Installer assigns port numbers to components from a set of default port numbers. This appendix lists the default port numbers and describes how to change the assigned port after installation. It includes information about the following topics:
During installation, Oracle Universal Installer assigns port numbers to components from a set of default port numbers. Many Oracle Database components and services use ports. As an administrator, it is important to know the port numbers used by these services, and to make sure that the same port number is not used by two services on your host.
Most port numbers are assigned during installation. Every component and service has an allotted port range, which is the set of port numbers Oracle Database attempts to use when assigning a port. Oracle Database starts with the lowest number in the range and performs the following checks:
Is the port used by another Oracle Database installation on the host?
The installation may be up or down at the time; Oracle Database can still detect if the port is used.
Is the port used by a process that is currently running?
This could be any process on the host, even a non-Oracle Database process.
Is the port listed in the /etc/services
files?
If the answer to any of the preceding questions is yes, Oracle Database moves to the next highest port in the allotted port range and continues checking until it finds a free port.
In most cases, the Oracle Database component's port number is listed 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, it is not updated in the portlist.ini
file, so you can only rely on this file immediately after installation. To find or change a port number, use the methods described in this appendix.
The following table lists the port numbers and protocols used by components that are configured during the installation. By default, the first port in the range is assigned to the component, if it is available.

To change the Oracle XML DB FTP and HTTP ports, you need to run the catxdbdbca.sql
script, which in a default installation is located in $
ORACLE_HOME
/rdbms/admin
.
To change the Oracle XML DB ports:
Check that the Oracle listener is running. To do so, in the Services control panel, make sure that the Oracle TNS Listener service (for example, OracleOraDb10g_home1TNSListener
) is set to Started.
If you cannot start the listener, refer to Oracle Database Net Services Administrator's Guide.
Log into SQL*Plus or iSQL*Plus as SYS
or XDB
using the SYSDBA
role.
For example, to log in to SQL*Plus as SYS
using the password welcome
:
# sqlplus "sys/welcome as SYSDBA"
Run the catxdbdbca.sql
script.
For example, to use 2200
for the FTP port and 8200
for the HTTP port, and assuming your Oracle home is in the following location, enter the following command:
SQL> $ORACLE_HOME/rdbms/admin/catxdbdbca.sql 2200 8200
Exit SQL*Plus or iSQL*Plus.
