Manually created user (APEX_040200), but now I'm not able to drop that user/schema.

Answer 1

This error code:

ORA-20900: DROP USER APEX_040200 not allowed.

represents user-defined exception in trigger named RDSADMIN.RDS_DDL_TRIGGER2 (user errors range is from -20000 to -20999). It means that someone (DBA? Amazon?) doesn't allow you to drop user. Is it only APEX_040200 or any user, depends on what code that trigger contains.
