E Managing Oracle Database Port Numbers

This appendix lists the default port numbers and describes how to change the assigned port after installation:

E.1 About Managing Ports

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:

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.

E.2 Viewing Port Numbers and Access URLS

In most cases, the port number of the Oracle Database component 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_BASE\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.

E.3 Port Numbers and Protocols of Oracle Components

Table E-1 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.

Table E-1 Ports Used in Oracle Components

Component and Description Default Port Number Port Range Protocol

Oracle SQL*Net Listener

Allows Oracle client connections to the database over the Oracle SQL*Net protocol. You can configure this port number during installation. To reconfigure this port, use Net Configuration Assistant.

Oracle Data Guard

Shares the SQL*Net port and is configured during installation. To reconfigure this port, use Net Configuration Assistant to reconfigure the Oracle SQL*Net listener.

1521

TCP

Connection Manager

Listening port for Oracle client connections. It is not configured during installation, but can be configured using Net Configuration Assistant.

1630

TCP

Oracle Management Agent

HTTP port for Oracle Management Agent, which is part of Oracle Enterprise Manager. It is configured during installation.

"Changing the Oracle Enterprise Management Agent Port" explains how to modify its port number

Oracle Enterprise Manager Database Control

HTTP port for Enterprise Manager Database Control. It is configured during installation. "Changing the Oracle Enterprise Manager Database Console Ports" explains how to modify its port number.

1158

5500–5519

TCP/HTTP

Oracle Enterprise Manager Database Console

RMI port for Enterprise Manager Database Control. It is configured during installation."Changing the Oracle Enterprise Manager Database Console Ports" explains how to modify its port number.

5520

5520–5539

TCP

Enterprise Manager Database Console

JMS port for Enterprise Manager Database Control. It is configured during installation. "Changing the Oracle Enterprise Manager Database Console Ports" explains how to modify its port number.

5540

5540–5559

TCP

Oracle Ultra Search

JMS port for Oracle Ultra Search. Its port number is assigned automatically when you install Oracle Ultra Search, by using the Custom installation type. "Changing the Oracle Ultra Search Ports" explains how to change its port number.

5660

5660–5679

TCP

Oracle XML DB

The Oracle XML DB HTTP port is used if Web-based applications need to access an Oracle database from an HTTP listener. It is configured during installation, but you cannot view it afterward. "Changing the Oracle XML DB Ports" explains how to change its port number.

Dynamic

Oracle XML DB

The Oracle XML DB FTP is used when applications need to access an Oracle database from an FTP listener. It is configured during installation, but you cannot view it afterward. "Changing the Oracle XML DB Ports" explains how to change its port number.

FTP

Oracle Clusterware

Oracle Clusterware Daemon internode connection. The port number is assigned automatically during installation. You cannot view or modify it afterward.

Cluster Synchronization Service (CSS)

CSS daemon internode connection for the GM layer. The port number is assigned automatically during installation. You cannot view or modify it afterward.

Oracle Services for Microsoft Transaction Server

The port number for Microsoft Transaction Server is configured when you enter its value in Oracle Universal Installer during a Custom installation the first time you install it on a particular computer. If you install it in multiple Oracle homes on the same computer, Oracle Universal Installer uses the same port number that you specified during the first installation.

In most cases, you do not need to reconfigure the port number. If you need to, you can edit its value in the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\OracleMTSRecoveryService\Protid_0 Registry Editor key.

E.4 Changing the Oracle Enterprise Management Agent Port

To find the current setting for the Oracle Management Agent port, search for EMD_URL in the ORACLE_BASE\ORACLE_HOME\host_sid\sysman\config\emd.properties file.

To change the Oracle Management Agent HTTP port, use the emca -reconfig ports command:

emca -reconfig ports -AGENT_PORT 1831

E.5 Changing the Oracle Enterprise Manager Database Console Ports

To find the current HTTP, RMI, and JMS port settings, search in the following files:

To change the Oracle Enterprise Manager Database Console ports, use the emca -reconfig ports command:

ORACLE_BASE\ORACLE_HOME\bin> emca -reconfig ports option setting

where option can be:

You can enter multiple -reconfig port settings in one line, for example:

emca -reconfig ports -DBCONTROL_HTTP_PORT 1820 -AGENT_PORT 1821 -RMI_PORT 5520

E.6 Changing the Oracle Ultra Search Ports

The following sections describe how to change the Oracle Ultra Search ports.

Changing the HTTP Port

To change the HTTP port, modify the port attribute of the web-site element in the $ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/http-web-site.xml file:

<web-site port="5620"...>

Changing the RMI Port

To change the RMI port, modify the port attribute of the rmi-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/rmi.xml file:

<rmi-server port="5640"...>

Changing the JMS Port

To change the JMS port, modify the port attribute of the jms-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/jms.xml file:

<jms-server port="5660"...>

E.7 Changing the Oracle XML DB Ports

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_BASE\ORACLE_HOME\rdbms\admin.

To change the Oracle XML DB ports:

  1. Check that the Oracle listener is running. To do so, in the Windows Services utility, make sure that the Oracle TNS Listener service (for example, OracleOraDb11g_home1TNSListener) is set to Started.

    If you cannot start the listener, see Oracle Database Net Services Administrator's Guide.

  2. Log in to SQL*Plus as SYS or XDB using the SYSDBA role.

    For example, to log in to SQL*Plus as SYS using the password password:

    DRIVE_LETTER:\sqlplus /nolog
    SQL> CONNECT SYS AS SYSDBA
    Enter password: password
    
  3. 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> @c:\app\username\product\11.1.0\db_1\rdbms\admin\catxdbdbca.sql 2200 8200
    
  4. Exit SQL*Plus.
