These come to mind: 1. use of public synonyms in packaged apps. 2. use of overly broad sys_privs in an application role, e.g. select any ta= ble 3. differences in availability: maintenance windows, uptime agreements, patchset frequency 4. lack of point in time tablespace recovery in Standard Edition 5. lack of consensus by a matrix management of application owners on what color the database should be.
