Upgrading OIM 10g to 11g

Here is the white paper talking about upgrading Oracle Identity Manager 10g to 11g.

The upgrade plan from OIM 10g to 11gR2 made of two parts:

•  Upgrading OIM 10g to OIM 11gR1 (11.1.1.5)
• Upgrading OIM 11gR1 (11.1.1.5) to OIM 11gR2 (11.1.2)

OIM 11g Configuration error

Oracle releases products oftentimes and hence it is very difficult to know which version to use and what is certified. I am talking about OIM 11gR1 version with WLS, SOA Suite and RCU.

With OIM 11.1.1.5.0 it is certified with WLS 10.3.5, SOA Suite 11.1.1.5.0 and RCU 11.1.1.5. However with products releasing, they won't appear on OTN, instead you have to download from edelivery. Well, it is a problem if we don't have account.

So I downloaded WLS 10.3.6, SOA Suite 11.1.1.6.0 and Oracle IAM Suite 11.1.1.5. I installed Oracle IAM Suite 11.1.1.5 and failed at OIM configuration step. I wrote a detailed post on the error messages and action plan. Well, it is actually version mismatch. Oracle Identity Manager should be upgraded to 11.1.1.5.2 to use WLS 10.3.6, SOA Suite 11.1.1.6.0.

Oracle Identity Manager Performance tips

I have read a post on Oracle Identity Manager performance tips here. This post talks about various factors where tuning has to be applied with respect to OIM. In addition, it is always good to tune the application server where OIM is deployed as a web application.
