Check this out: IAM 11G Rel2 V8

Oracle lanched Identity and Access management 11G Release 2, Version 8 (also known as V11.1.2.2.0) two weeks ago.
You should check it out. Some reasons why:

1. Installation is so much easier
2. Installation is error proof (the "just MUST run configuresecurity first, or redo all" error can not occur. Tested it)
3. The interface (OAM Console) has had a major overhaul. It responds faster and is more consistent.

Really. Oracle did a fine job here.
