3 Installation Issues

3.1 IPv6 Not Supported

This release of Oracle Application Server is not certified to run on machines that are configured with IPv6. You have to install and run this release of Oracle Application Server on machines that are configured with IPv4.

3.2 DHCP Warning Message with Static IP Addresses (Vista and Windows 2008)

When installing on a Microsoft Vista or Windows 2008 system with a valid, DNS-registered static IP address, you may see the following error:

A DHCP configuration was detected on this host. The installer also detected
that the local hostname and the network hostname differ. Please resolve the
networking issues by referring the "Installing on DHCP Computers" section in
the installation guide.

This problem occurs if you have multiple network adapters with the same name and one of them is enabled for DHCP.

Workaround

1. Set a dummy static IP address on the network adapter that is enabled for DHCP.

2. Restart the installation.

3. Restore the original network adapter configuration information.

3.3 Installer Hangs When It Tries to Restart OPMN (Vista and Windows 2008)

On Microsoft Vista and Windows 2008 systems, when you perform the basic installation type, the installer may hang when it tries to restart OPMN (right before it runs the configuration assistants).

To work around this issue, check the following:

• Ensure that you are not running IPv6. By default, Vista and Windows 2008 run IPv6, which is not supported by this release of Oracle Application Server. To disable IPv6:

  1. Remove or comment out the following line in the C:\Windows\System32\drivers\etc\hosts file:

     ::1 localhost
     

  2. Deselect IPv6 for all your connections and adapters, using the Network Connection Properties page. The page is available from Control Panel.

  3. Open the Registry Editor.

  4. Create the following registry entry as type DWORD, and set its value to 0xFF:

     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents

  5. Exit the Registry Editor.

  6. Restart the computer.

• Start up the installer from a command shell that was started with "run as Administrator". To do this, right click cmd.exe in Windows Explorer, and select "Run as Administrator".
