# B Default Port Numbers

By default, the installer assigns port numbers to components from a set of default port numbers. This appendix contains a list of these port numbers.

If you want to use a different set of port numbers, you have to create a file called staticports.ini, in which you list the port numbers that you want to use. See Section 2.5.3, "Using Custom Port Numbers (the "Static Ports" Feature)" for details.

This appendix contains the following topics:

- Section B.1, "Method of Assigning Default Port Numbers"

- Section B.2, "Default Port Numbers"

- Section B.3, "Ports to Open in Firewalls"

## B.1 Method of Assigning Default Port Numbers

The installer assigns default port numbers to each component using the following method:

1. The installer checks if the default port number is in use. If it is not in use, the installer assigns it to the component.

2. If the default port number is already in use by an Oracle product or by any running application, the installer tries the lowest number in the port number range. It keeps trying the port numbers in the range until it finds one that is available.

## B.2 Default Port Numbers

Table B-1 lists the default port numbers for components. The last column, Name in staticports.ini, specifies the component name as it appears in the `staticports.ini` file, which enables you to override the default port numbers. See Section 2.5.3, "Using Custom Port Numbers (the "Static Ports" Feature)" for details.

## B.3 Ports to Open in Firewalls

If you plan to install Oracle Application Server behind firewalls, you need to open certain ports in the firewall during installation (and also during runtime).

For a 10g Release 3 (10.1.3) middle-tier instance, you need access to Oracle Notification Server and AJP ports. You need to open the following ports used by these components in the firewall:

- OPMN Oracle Notification Server remote port

- OC4J AJP port
