OBIEE 11.1.1.7.0 Installation in 12C

what we need to prepare in OBIEE installation: 

1) The BIPLATFORM SCHEMA and MDS SCHEMA -> if we don't have the schema, we can create it using RCU (RUNNING REPOSITORY CREATION UTILITY)

2) OBIEE Installer --> download from OTN http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/downloads/bus-intelligence-11g-165436.html

3) Follow the steps,
