Changing from a Static IP Address to DHCP

15-14 Oracle Fusion Middleware Administrators Guide This URL takes you to the single sign-on home page. If you are able to log in, you have configured the proxy correctly. 2. If you have not already done so, install Oracle HTTP Server 11g Release 1 11.1.1 to use as a reverse proxy for IPv6. 3. Change the Oracle HTTP Server 11g Release 1 11.1.1 configuration to enable reverse proxy: a. Stop Oracle HTTP Server: opmnctl stopproc ias-component=component_name b. Edit the following file: UNIX ORACLE_INSTANCEconfigOHSohs_namehttpd.conf Windows ORACLE_INSTANCE\config\OHS\ohs_name\httpd.conf Append the following to the httpd.conf file: ---Added for Mod Proxy ProxyRequests Off Proxy Order deny,allow Allow from all Proxy ProxyPass sso http:OHS_host:OHS_portsso ProxyPass http:OHS_host:OHS_port ProxyPassReverse http:OHS_host:OHS_port ProxyPreserveHost On In the example, OHS_host and OHS_port are the host name and port of the front-end server for Oracle Single Sign-On, discussed in Step 1. c. Restart the Oracle HTTP Server. For example, to restart ohs1: opmnctl startproc ias-component=ohs1

15.5.5 Configuring Oracle Access Manager Support for IPv6

Oracle Access Manager supports Internet Protocol Version 4 IPv4. Oracle Fusion Middleware supports Internet Protocol Version 4 IPv4 and Internet Protocol Version 6 IPv6. IPv6 is enabled with Oracle HTTP Server with the mod_wl_ohs plug-in. You can configure Oracle Access Manager to work with clients that support IPv6 by setting up a reverse proxy server. Several scenarios are provided here. Be sure to choose the right configuration for your environment. This section describes configuring Oracle Access Manager 10g for IPv6. For information about configuring Oracle Access Manager 11g for IPv6, see Configuring OAM 11g for IPv6 Clients in the Oracle Fusion Middleware Administrators Guide for Oracle Access Manager with Oracle Security Token Service.
