Changes in Oracle Access Manager 11g R1 (

This post covers changes in Oracle Access Manager from 10g (10.1.4.X) to 11g (11.1.1.X).

Oracle Access Manager (OAM) : is Access Management Product acquired from Oblix in 2005. 

  • Oblix COREid (6, 7) and OAM 10g is written in C++where as OAM 11g is J2EE application deployed on Oracle WebLogic Server (10.3.3+)
  • There are two main OAM components in OAM 10g, Access System(Access Server, WebGate and Policy Manager) and Identity System (Identity Server and WebPass). In OAM 11g there is NOIdentity System Component“. Identity related functions are moved to Oracle Identity Manager(OIM) 11g. (OIM is user provisioning and reconciliation product acquired from Thor Xellerate)
  • There is NO identityXML interface or Workflow in OAM 11g.
  • Access Server in 10g is now called as OAM Server in 11g
  • Policy Manager in 10g is now called as OAM Administration Console in 11g
  • AccesssGate and WebGate in 10g are now called as OAM Agents in 11g
  • Directory Profiles in 10g are now called as User-Identity Store in 11g
  • In OAM 10g configurations are stored in LDAP servers where as in OAM 11g configurations are stored in xml file (under webloigic domain) – $DOMAIN_HOME/config/fmwconfig/oam-config.xml
  • In OAM 10g Policies are stored in LDAP server where as in OAM 11g you have option to store them either in XML file or in Database.
  • In OAM 10g Sessions used to be stateless where as in OAM 11g, user sessions are stateful and stored on Server in OAM 11g (It is possible to leverage Coherence for distributed caching of session data). For more information on Oracle Coherence (earlier Tangosol) click here
  • In OAM 11g (by default) Policy Data & User session datais stored in single database (details under $DOMAIN_HOME/config/jdbc/oam-db-jdbc.xml) under one schema however it is possible to configure OAM Policy Data in to one database and user session data in another database. 
  • OAM Server (Access Server in 10g) in OAM 11g is deployed on WebLogic Managed Server (oam_server1 – default port 14100)
  • In OAM 11g, OAM Administration Console(Policy Manager in 10g) is deployed on WebLogic Admin Server (default port 7001)
  • URL for OAM Administration Console is http://server:7001/oamconsole (default username/password created during domain creation in weblogic)
  • OAM 11g User Interface (UI) is based on Application Development Framework (ADF)
  • Three type of Web Agents are supported in OAM 11g –
    a) AccessGate/WebGate from 11g
    b) AccessGate/WebGate from 10g (for backward compatibility) and
    c) mod_osso for Oracle 10g Single Sign-On integration

Well Done, Atul. Comprehensive and compact.

Kanti says September 6, 2010

Hi Atul,

This information is very useful.

You could as well provide details on the migration/upgrade path to 11g OAM and possibly use of it in a few scenarios.Maybe that warrants a new post 🙂

Hi Atul,

I wanted to know how the OAM behaves with protected and unprotected URL’s.

Pleas explain how to specify the resource URL’s in OAM 11g.

and is it necessary to have public URL’s for appliction.


Atul Kumar says November 22, 2010

Check this

and revert back in case of any issues.

Q: Pleas explain how to specify the resource URL’s in OAM 11g.

Step by step coming soon (in 2-3 weeks time)

Q. Is it necessary to have public URL’s for appliction ?

Yes in 11g you must define pubblic (unprotected pages) as by default all pages are secured in OAM 11g

Rahul says December 13, 2010

What is the difference between stateful & stateless sessions?

Atul Kumar says December 14, 2010

@ Rahul,
In OAM 10g and previous release loogged-in/active users information was not stored on OAM server where as in OAM 11g , Access Manager maintains state of users session like who has logged on at what time + if that user is active or not in OAM servers memory (which is distributed to other OAM managed server (in HA deployment) using Coherence solution).

while installing oam Oracle Access Manager Identity Server

i am getting following error…
i am installing on ubuntu 10.10 can you please provide solution thank you

The product that you are about to install needs to be owned by a dedicated
user. Only root or the dedicated user may be able to start the service. Most
of the time the server is run as `root’ or `nobody’.

Enter the username the Identity server is running as [nobody] oamuser

Enter the Group for the above username [nobody] oamuser

Press 1 for Next, 2 for Previous, 3 to Cancel or 4 to Redisplay [1] 1

Sorry, invalid user `oamuser’ or invalid group `oamuser’.
Please check and enter again

Atul Kumar says May 20, 2011

@ Mohankumar,
As what user you are running Identiy Server installer ?

Do you have user oamuser and group aomgroup already in system
