Why am I getting ORA-06502

Question

Hi:
I have the following call in a form trigger:
ERROR_MSG('Access denied');
Here is the detail on ERROR_MSG, which is in a pll (base.pll):
PROCEDURE ERROR_MSG(
                     P_MSG                 VARCHAR2,
                     USE_ALERT             BOOLEAN  := FALSE,
                     P_TITLE               VARCHAR2 := '',
                     RAISE_FAILURE         BOOLEAN  := TRUE,
                     USE_LONG_MSG          BOOLEAN := FALSE
IS
  V_ALERT_ID          ALERT;
  V_ALERT_RESPONSE    NUMBER;
  V_MSG               VARCHAR2(32767) := P_MSG;
BEGIN
  CLEAR_MESSAGE;
  IF SUBSTR(V_MSG, -1) <> '.' THEN
    V_MSG := V_MSG || '.';
  END IF;
  IF USE_LONG_MSG THEN
       VIEW_LONG_MESSAGE(V_MSG, P_TITLE);
  ELSE
    IF USE_ALERT THEN
      V_ALERT_ID := FIND_ALERT('OK_ALERT');   
      IF ID_NULL(V_ALERT_ID) THEN
        MESSAGE(REPLACE(V_MSG, CHR(10)));
      ELSE
        SET_ALERT_PROPERTY(V_ALERT_ID, TITLE, NVL(P_TITLE, 'Error'));
        SET_ALERT_PROPERTY(V_ALERT_ID, ALERT_MESSAGE_TEXT, V_MSG);
        V_ALERT_RESPONSE := SHOW_ALERT(V_ALERT_ID);
      END IF;
    ELSE
      MESSAGE(REPLACE(V_MSG, CHR(10))); -- I am getting this message
    END IF;
  END IF;
  IF RAISE_FAILURE THEN
    RAISE FORM_TRIGGER_FAILURE;
  END IF;
END;I am getting the message in the line marked "I am getting this message"
My problems is that I am also getting ORA-06502 error message after the "Access Denied" meesage.
Does anybody have an idea why?

Answer 1

I suspect that whatever trigger or procedure is issuing the "Access denied" message is not causing the ORA-06502: PL/SQL: numeric or value error message. What trigger are you issuing the message from? Is there some other trigger or procedure running? If it is issuing some sort of navigational command, which is causing the current procedure to issue the "Access denied" error message, but NOT checking
    If not form_success then
      Raise Form_trigger_failure;
    End if;then it may be proceeding, and then encounters the 6502 problem.
