Drop the Existing ODI Repository Schema
Use the Oracle BI Applications repository creation utility (RCU) to drop the existing 11.1.1.10.3 ODI Repository schema.
When you are prompted with a list of schemas installed, select the schema where the ODI repository for 11.1.1.10.3 exists. Only drop the
<prefix>_BIA_ODIREPO
schemas. Don’t drop any other schema.
