2. After creating the user, we authorize her according to which schema and table we want it to use.

3. Add the following line to the pg_hba.conf file.

4. After making the change, we reload the service.

3. Create the initPG.ora file in the ORACLE_HOME/hs/admin directory and add the following lines to it.

4. Add the following lines to the tnsnames.ora file.

5. Add the following lines to the listener.ora file.
