Ports
2-12 Oracle Application Server Installation Guide
The installer verifies that the ports specified in the file are available by checking
memory. This means that it can only detect ports that are being used by running
processes. It does not look in configuration files to determine which ports an
application is using.
If the installer detects that a specified port is not available, it displays an alert. The
installer will not assign a port that is not available. To fix this:
1. Edit the staticports.ini file to specify a different port, or shut down the
application that is using the port.
2. Click Retry. The installer re-reads the staticports.ini file and verifies the
entries in the file again.
Using portlist.ini as the staticports.ini File
The staticports.ini file uses the same format as the ORACLE_
HOME/install/portlist.ini
file, which is created after an Oracle Application
Server installation. If you have installed Oracle Application Server and you want to
use the same port numbers in another installation, you can use the portlist.ini file
from the first installation as the staticports.ini file for subsequent installations.
However, note this difference: in staticports.ini, the line "Oracle Management
Agent port
" corresponds to "Enterprise Manager Agent port" in
portlist.ini .
2.5.3.2 Error Conditions that Will Cause the Installer to Use Default Ports Instead
of Specified Ports
Check your staticports.ini file carefully because a mistake can cause the installer
to use default ports without displaying any warning. Here are some things that you
should check:
■
If you specify the same port for more than one component, the installer will use
the specified port for the first component, but for the other components, it will use
the components’ default ports. The installer does not warn you if you have
specified the same port for multiple components.
■
If you specify different ports for one component on multiple lines, the installer
assigns the default port for the component. The installer does not warn you if you
have specified different ports for one component.
Notes on Choosing Port Numbers:
■
Port numbers cannot be greater than 65535.
■
If you use a port number less than 1024 for a component, you
must run the component as the root user.
■
If you use a port number less than 1024 for a component, the
installer will not be able to start up the component at the end of
installation. You may need to configure the component first
before you can start it up. See the appropriate component
documentation for details.
■
You still have to comment out ports 389 and 636 in the
/etc/services
file if you want to use these port numbers for
Oracle Internet Directory. See the Note on page 2-10 for details.
