Access Manager 11gR2
Installation and Configuration
• Installation process
• OAM 11g installs using Oracle Universal Installer (OUI)
• The installation process copies all the software bits to the host
machine
• OUI does not perform product configuration
• Configuration process requires 2 steps
• Database schema configuration using Repository Creation
Utility (RCU)
• Product configuration and deployment using WebLogic
Configuration Wizard
• Oracle Support Note 340.1 provides a good starting point

Windows Native Authentication
• SPNEGO based credential validation for true Windows
desktop to web single sign-on
• Allows single sign-on for WebGate and Oracle SSO protected
applications simultaneously
• Does not need IIS based solution for WebGate
• WebGates and Oracle SSO protected applications need
not run on Windows platform
• Can be enabled for a subset of protected applications
• Internal vs External websites

OAM 11gR2- Migration and
Coexistence with OSSO
- 23 -
Oracle Access Manager 11g
OSSO 10g Upgrade
• Facilitated through AS Upgrade Assistant
• Process:
• Install OAM 11g
• Run Upgrade Assistant pointing to Oracle AS Single-On
10.1.4.3
• Two modes:
• Retain Ports: no changes required on partner sites
• Change Ports: partner sites need new osso.conf which is
generated by the Upgrade Assistant
• See Support Migration Advisor (note 343.1) and upgrade
viewlet (note 1230123.1)
- 24 -
Co-existence: OAM11g & SSO 10g
Supports OracleAS SSO 10g Release (10.1.2.0.2) through
OracleAS SSO 10g Release (10.1.4.3.0)
Co-existence requires same back-end user identity store:
Oracle Internet Directory (OID)
- 25 -
Co-existence: OAM11g & SSO 10g
• mod_osso redirects requests to the 11g OAM Server for authentication
through a proxy.
• mod_wl replaces mod_oc4j. mod_wl enables SSO to work without any
changes on the OHS
Without Proxy
- 26 -
Co-existence: SSO between Partner
Applications
App1 upgraded to OAM11g
User accessing App1
OAM sets the SSO cookie and
updates session information
accordingly.
The cookie includes a flag
indicating that an OSSO
cookie must also exist for this
cookie to be valid.
