The following topics describe how to define the Task 1: Enable Oracle HTTP Server to Run as Root for Ports Set to Less Than 1024 (Unix Only) If you are on a UNIX system and you are changing the Listen port to a number less than 1024, perform these steps before you change the Oracle HTTP Server Listen port.
Most port numbers are assigned during installation.
Every component and service has an allotted port range, which is the set of port numbers Oracle Application Server attempts to use when assigning a port.
The Oracle Application Server instance must be restarted—or stopped and started—before the port changes take effect.
With this option, only already running components are restarted after the configuration changes are complete.
In addition, this file is not valid after you upgrade Oracle Application Server.
Use Application Server Control Console to view the port numbers.To configure them, you must manually add them to the file.See the J2EE Interoperability chapter of the To change the Oracle HTTP Server Listen ports, you change the Oracle HTTP Server Listen directive.The AJP and RMI port ranges are required; the others are optional.Note: Note that because the IIOP, IIOPS1, and IIOPS2 ports are not configured by default, they may not be listed in the Ports page of Application Server Control Console or in During runtime, each OC4J instance on the host is assigned a single free port from the range.
