If you're reading this and you want to install Oracle Identity and Access Management 11g Release 2 (11.1.2.2), specifically OAM 11gR2PS2, then you need to install Oracle Identity and Access Management Release 2 (11.1.2.1) THEN patch that version to get to OAM 11g R2 PS2. Sadly, Oracle does not provide OIM 11gR2PS2 as a single, distributed package from My Oracle Support (or from their cloud services). No idea why they've done this though in order to install OAM 11gR2 PS2, you need to install OAM 11gR2 then perform a 'patch update'. (WHY ORACLE, WHY!?!)

If you don't believe me, check it out here

So in order to install OAM 11gR2, you will need to following:

• For Oracle Identity and Access Management 11g (11.1.2.0.0), go to the Oracle Software Delivery Cloud and download V33644-01_1of2 and V33644-01_2of2
• For Oracle Fusion Middleware Repository Creation Utility 11g (11.1.1.9.0) go to V75907-01, which can be downloaded from the Oracle support cloud

Go ahead and start the installation of the RCU by following the link, HOW TO: Install Oracle RCU 11.1.1.5. This step is pretty much the same process. The only difference is that you need install 11.1.1.9 to select Oracle Access Manager and not Oracle Identity Manager in step 2.

There's the link on HOW TO: Install Weblogic 10.3.6.

The fusion middleware Identity and Access Management 11g package you download needs to be extracted into one folder then executed. The installation for OAM is pretty much the same process as the HOW TO: Install OIM (11gR2) 11.1.2.0 on Linux 64bit post that was made earlier

Sadly I decided to remove the screenshot though rest assure it's pretty much like installing OIM. Click here on how to configure your domain.

Once you've installed and configured OAM, you then perform WLS 10.3.6 - Configure Database Security Store The full script in question is as follows:
/home/oracle/Oracle/OAM11gR2PS2/oracle_common/common/bin/wlst.sh /home/oracle/Oracle/OAM11gR2PS2/Oracle_IDM1/common/tools/configureSecurityStore.py -d /home/oracle/Oracle/OAM11gR2PS2/user_projects/domains/oam_domain/ -c IAM -p Password1 -m create

Once you've executed the script,
Credential with map Oracle-IAM-Security-Store-Diagnostics key Test-Cred stored successfully!
Credential for map Oracle-IAM-Security-Store-Diagnostics and key Test-Cred is: GenericCredential
Info: diagnostic credential created in the credential store.
Info: Create operation has completed successfully.

Further information on how to configure Weblogic for OAM can be located here: WLS 10.3.6 - Configure Database Security Store

As mentioned, you need to install OAM 11gR1 in order to install OAM11gR1PS2. A useful oracle document can be located here. The steps are fairly similar to the actual installation though the only difference is that you point to the existing middleware home for OAM 11gR1. The installer will acknowledge that an existing middleware deployment already exists and therefore provide you an option on whether or not to upgrade. Here is the link to download RCU 11.1.2.2. The database schema upgrade is also required as part of the OAM 11gR1PS2 installation.
