This document provides instructions for creating master and work repositories in Oracle Data Integrator (ODI). It describes: 1) Creating schemas named ODI_MASTER, ODI_WORK, and WORK_SCHEMA to store the repositories and use as a work schema. 2) Using scripts to create the users and grant privileges. 3) Setting environment variables and paths to connect to the ODI installed folder in UNIX. 4) Running tools like REPCREATE.BAT to create the master repository connected to the ODI_MASTER schema. 5) Logging into the topology manager and creating a work repository connected to the ODI_WORK schema.
