If you used a virtual host URL while registering the partner application, you must define the virtual host by updating httpd.conf on the Oracle HTTP Server that is used as the EPM System web server.
To define a virtual host:
Using a text editor, open EPM_ORACLE_INSTANCE/httpConfig/ohs/config/OHS/ohs_component/httpd.conf.
Add a definition similar to the following. This definition assumes that the web server is running on the virtual server epm.myCompany.com at port epm.myCompany.com:19400. Modify the settings to suit your requirements.
NameVirtualHost epm.myCompany.com:19400 Listen 19400 <VirtualHost epm.myCompany.com:19400> DocumentRoot "C:/Oracle/Middleware/user_projects/epmsystem1/httpConfig/ohs /config/OHS/ohs_component/private-docs" include "${ORACLE_INSTANCE}/config/${COMPONENT_TYPE} /${COMPONENT_NAME}/mod_osso.conf" </VirtualHost>
