Failed:oracle.webdb.dispatcher.DispatcherException: I/O Error dispatching request

The Middle Tier HTTP home page at http://<http_server_host>:<http_server_port> works.

In other scenarios, when accessing Portal from IE, an HTTP 500 Internal Server Error may be displayed in the browser while the URL is shown as http://<reverse_proxy_host>:<reverse_proxy_port>/sso/auth.

The Portal pages are accessed through a reverse proxy.

  1. Have a Portal configuration front-ended by a Reverse Proxy.
  2. Change the IP addresses of the Portal middle tier and the infrastructure.
  3. Run the script "chgiphost" as documented at:
    Oracle® Application Server Administrator's Guide 10g
    8.2 Changing the Hostname, Domain Name, or IP Address
  4. Notice the above error when trying to access the Portal's welcome page at
    http://<reverse_proxy_host>:<reverse_proxy_port>/portal/page/portal/TOPLEVELSITE/Welcome
