This is part 2 of http://blogs.oracle.com/pankaj/2010/11/upgrade_10g_osso_to_11g_oam.html

So last post we saw the overview of upgrading osso to oam11g . Now some more details on same .

As we are using the co-existence feature , we have to install the OAM server and upgrade the existing OSSO 10g server to the OAM servers.

OAM Upgrade Steps Overview
Pre-Req : You already have a OAM 11g Installed
Upgrade Step 1: Configure User Store & Make it Primary
Upgrade Step 2: Create Policy Domain , this is dome by UA automatically
Upgrade Step 3: Migrate Partners : This is done by running Upgrade Assistant
Verify successful Upgrade

Details on UA step :
To Upgrade the existing OSSO 10g servers to OAM server , this is done by running the UA script in OAM , which copies over all the partner app details from osso to OAM 11g , run_ua.sh is the script name which will ask you to input the Policies.properties from SSO $OH/sso/config folder of osso 10g & other variables like db password .

Some pointers


  • Upgrading oso to Oam 11g , by default enables the coexistence mode on the OAM Server

  • Front-end the OAM server with the same Load Balancer that is the front end of the OSSO 10g servers.

  • Now, OAM and OSSO 10g servers are working in a co-exist mode.
  • OAM 11g is made to understand 10g OSSO Token format and session handling capabilities so as to co-exist with 10g OSSO servers.<>/li

How to test ?

Try to access the partner applications and verify that single sign on works. Also, verify that user does not have to login in if the user is already authenticated by either OAM or OSSO 10g server.
