D Managing Oracle Database Companion CD Port Numbers

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 sections:

D.1 About Managing Ports

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 ensure that a port number is not used by more than one service 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?

Oracle Database can detect if the port is in use, regardless of whether or not the other installation is running.
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, then Oracle Database moves to the next highest port in the allotted port range and continues checking until it finds a free port.

D.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_HOME/install directory.

When you change a port number, it is not updated automatically in the portlist.ini file. Therefore, you can rely on the information in this file for only as long as the port numbers are not changed. To change a port number, use the methods described in this appendix.

D.3 Port Numbers and Protocols of Oracle Components

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.

D.4 Changing the Oracle HTTP Server Port

To change the Oracle HTTP Server port:

In the Oracle HTTP Server home, modify the following settings in the $ORACLE_HOME/Apache/Apache/conf/httpd.conf file:
```
Port port
Listen listener
```

Restart Oracle HTTP Server:

$ORACLE_HOME/opmn/bin/opmnctl restartproc ias-component=HTTP_Server

D.5 Changing the Oracle Workflow Container Ports

The following sections explain how to change the HTTP, RMI, and JMS ports for the Oracle Workflow Component Containers and Management Containers.

Changing the HTTP Port

To change the HTTP port, edit the following files:

Oracle Workflow Component Container: $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Component_Container/config/http-web-site.xml

Modify the port attribute of the web-site element:
```
<web-site port="6001" ...>
```
Oracle Workflow Management Container: $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Management_Container/config/http-web-site.xml

Modify the port attribute of the web-site element:
```
<web-site port="6061" ...>
```

Changing the RMI Port

To change the RMI port for Oracle Workflow Component Container, modify the port attribute of the rmi-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Component_Container/config/rmi.xml file:

<rmi-server port="6041">

For Oracle Workflow Management Container, modify the port attribute of the rmi-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Management_Container/config/rmi.xml file:

<rmi-server port="6101">

Changing the JMS Port

To change the JMS port for Oracle Workflow Component Container, modify the port attribute of the jms-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Management_Container/config/jms.xml file:

<jms-server port="6021">

For Oracle Workflow Management Container, modify the port attribute of the jms-server element in the $ORACLE_HOME/oc4j/j2ee/OC4J_Workflow_Management_Container/config/jms.xml file:

<jms-server port="6080">

D.6 Changing the Oracle Ultra Search Ports

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