Before to use debug in SQLDeveloper we need to prepare the database to accept this request and we need to add grants to the user that activate a debug.

Preparing database environments:

create role SQLDEV_DEBUG_ROLE;

begin
 dbms_network_acl_admin.append_host_ace(host=>'*', 
                                        ace=> sys.xs$ace_type(privilege_list=>sys.XS$NAME_LIST('JDWP') , 
                                        principal_name=>'SQLDEV_DEBUG_ROLE', 
                                        principal_type=>sys.XS_ACL.PTYPE_DB) );
end;
/

grant debug connect session to SQLDEV_DEBUG_ROLE; 
grant debug any procedure to SQLDEV_DEBUG_ROLE;
grant execute on DBMS_DEBUG_JDWP to SQLDEV_DEBUG_ROLE;

grant SQLDEV_DEBUG_ROLE to scott;

--to Check
select * from dba_network_acls;
select * from dba_network_acl_privileges;
select host from dba_host_acls;

--Check firewall port from 4000 and 4199 (in both direction client/server)
