• Dropped and recreated all the indexes for the foreign keys with new column list.

• Created before update trigger for all the tables to set the update_date, update_user columns.

• Created and enabled the policy for all the tables using dbms_rls.add_policy

• Created a database procedure to set the VPD context for the user and called it in after logon database trigger.
