I mentioned about availability of Oracle Identity & Access Management version 11gR2 PS2 (188.8.131.52).
This post covers changes in installation from previous version of these components (OIM, OAM, OAAM, OES, OPAM) i.e.
a) 11gR1 – 184.108.40.206, 220.127.116.11, 18.104.22.168
b) 11gR2 – 22.214.171.124, 126.96.36.199
Installation steps are more or less same as 11gR1 or 11gR2 (including PS1) with following additional steps
1. You must upgrade the OPSS schema (XXX_OPSS) from 188.8.131.52.0 to 184.108.40.206.2
Note: When you create OPSS schema using 220.127.116.11 RCU, OPSS schema version is 18.104.22.168.0 . You must upgrade OPSS schema from 22.214.171.124.0 to 126.96.36.199.2 using Patch Set Assistant (PSA)
Note 1: By default security store (credential & policy store) is in XML file and this step migrates it to database in OPSS schema.
Note 2: This step is also required in 11gR2 and PS1 (188.8.131.52 & 184.108.40.206)
Note 3: In 11gR1 (220.127.116.11, 18.104.22.168) policy store could be set to either in XML, OID, or Oracle Database .
3. You can deploy IAM in 11gR2 PS 2 using IAM Lifecycle Tools (idmlcm) More information here (Deploying IAM using IDMLCM is optional)
Note: Deployment of IAM using IAM Lifecycle Management Tool (idmlcm) is mainly for Oracle Fusion Applications
