Doubts on Exceptions

Hi,
Need some inputs from MDM Implementation experts.
I have started working on SP06 sometime back (After working on SP04). Currently I am implementing MDM SP06 (latest patch) on Unix.
I need some guidance from guys who have already implemented MDM on SP06 wrt Exceptions.
1. After go-live, what types of exceptions do people receive?
As far as my understanding goes Structural exceptions should not come as structures of entire landscape would have been finalised. With SP06 I have heard you can make config changes in mdis.ini file and Import manager to make sure Value exceptions do not come. So are we left with only Import Exceptions post go-live?
I might be wrong on a few points so your comments on same are valuable.
2. I understand that if you get errors in 100 records out of 1000. MDIS writes 100 xml files for each failed record in Exception folder along with main log file.
If I am not incorrect MDM stores the entire file only for Structural Exception, not for Value/Import exceptions (for which it writes one XML per failed record). Please correct me here.
3. Lastly there are guys here who have implemented this. So what are their suggestions with respect to Exceptions. Some best practices, use cases, dos and donts etc would be very beneficial here.
In case you need to pass some documents please refer my Business card for further details (e mail).
Regards,
Dev.

*** Doubt regarding Exception Block ***

Hi,
I have a doubt regarding exception.
My SP has 5-6 select queries that is used in" open <cursor name> for select ...."
also a 'select count(id) into...' statement.
Do I need to have an Exception block inside? I dont have any user defined execptions at all. So will there be any exceptions that gets generated in a select query?
Also 'WHEN OTHERS THEN' is it OK to use where I dont know what all excaptions might occur?
Regds,

Hi,
Oracle will raise an error NO_DATA_FOUND , if any of your SELECT statement returns zero records, If you want your process to fail then you can have one common handler (either write to a error_log_table) do all the error_handling.
If you want to continue for some SQL's to move to the next statement then you can do some thing like this.
begin
select statement
when no_data_found then --not an issue, if no data is returned.
NULL;
Refere to this link for more information.

Doubt about exceptions.

hai,
here there is user eit function module.
call customer-function '014'
exporting
is_header          = is_caufvd
is_component       = cs_resbd_new
is_component_old   = is_resbd_old
is_materialview    = is_msfcv
i_fcode            = c_fcode
i_marked           = c_flg_sel
exceptions
no_changes_allowed = 01.
directly it taking data from screen. so here i have doubt that when that exception will raise.
tell me what is main use of exception.
some fm there is more than one exceptions is there?
so plz tell me about the use exception & changing in function module.

Hi,
CALL customer-function '014', is called from a standard program. There might be a case where depending on certain conditions you want to restrict the user from making changes on the screen. In that case you you will raise the exeption in the implementation of the user exit where you write your own code.
In this case
RAISE no_changes_allowed.
For further details on how to raise the exception, refer to the keyword 'RAISE'

Can you modify procedure in the following way. It will work for predefined Exceptions also
create or replace procedure del_job(p_jobid varchar2)

no_data_found raises only for select statements, the use of sql%notfound is correct for delete and update statements. You may use a raise no_data_found if You want to replicate what happens for selects.

Can you please clarify the doubt in Exception.

Can any body explain program especially catch block???

Exception e3 has as cause e2 which has aa cause e, where having a cause means 'this exception is caused by another exception'.
Usually exceptions as wrapped like this to add extra information, while retaining the original exception information.

Many thanks,

1) you cannot use a "when no_data_found" in an execution block.
It has to be part of the exception block.
2)
create or replace procedure proc1(n in number) as
nk number;
dte date;
myexcp exception;
begin
    select count(key1) into nk from DATE_TAB where key1 = n;
    if nk=0 then
      raise myexcp;
    else
      select dt, key1 into dte, nk from DATE_TAB where key1 = n;
      dbms_output.put_line(dte ||','|| nk);
    end if;
exception
when myexcp then
    dbms_output.put_line('In MY EXCEPTION');
when no_data_found then
    dbms_output.put_line('In no_data_found EXCEPTION');
    raise;
when others then
    dbms_output.put_line('In OTHERS EXCEPTION');
    raise;
end proc1;In this case, when the count is returning zero rows, we are explicitly raising the user-defined exception, in the execution block, using ...
raise myexcp;
So, the execution is terminated & the control is passed to the exception block where we are handling the "myexcp" exception.
3) But in your case ... create or replace procedure proc1(n in number)
as
nk number;
dte date;
myexcp exception;
begin
begin
select LAST_PRO_DATE,key into dte,nk from DATE_TAB where key=n;
dbms_output.put_line(dte||','||nk);
exception
when no_data_found then
raise myexcp;
end;
exception
when myexcp then
dbms_output.put_line('In MY EXCEPTION');
when no_data_found then
dbms_output.put_line('In No DATA');
end;you were trying to raise "myexcp" in the exception block & not in the execution block. Hope you are able to make out the difference.
Now, re-phrasing your question ...
"Does it mean that when we raise a user defined exception,
in the exception block in a procedure
having single begin-end block then the user defined exception is not handled,
because it cannot propagate more ...
... But if we put a begin and end before the select statement
it should be caught.Am I right?" ...
The answer is ... "YES"

Exceptions in Query designer

Hello experts,
I have a basic doubt on Exceptions in the Query designer.
Say I create an exception which says any value between 1 and 10 is good and should have a certain color and another exception on the same key figure which says that values between 8 and 12 are bad and denote with a different color.
Now I get a value 0f 9 for my Kf then how does BI process the exception?
Thanks and Regards
Ankit

Hi,
You have to make exception for values 1-10 as per the requirement.
and starting from 11-12 give another with diff color and notation. Like wise it's better to identify.

Highest peak rates for replicated DVD-9 or DVD-5?

Which is the highest peak rate that is most commonly used for replicated discs for all the data streams, and for video? I've tested some well authored popular mass production music dvds with DGIndex and often found video peak rates to go over 8.5 or even 9.
Still quite often it's said for example here http://www.createspace.com/Special/AuthoringNightmares/03/BitsAndBytes.jsp?cfxwasredirect ed=true
that for replicated discs you shouldn't go over 8Mbps rates for video.
I'm having one subtitle track and, 2.0 Dolby Digital and 5.1 Dolby Digital audio tracks in my project, but if the spec says the peak limit for all the assets in DVD-video is around 10Mbps, 9.8Mbps (as I think Neil referred in his alternate bit budgeting guide: http://www.adobeforums.com/webx/.3bb7dccd ) or as 9.6 (as I think Neil referred in: http://www.adobeforums.com/webx/.3bc2e248/0 ) why the video peak rate needs to be that much under what would be possible to be used with subtitles, 2.0 and 5.1 audios? There is like 0.448 Mbps for 5.1audio, 0.256Mbps for 2.0audio, 0.04 Mbps for subtitle, it would leave at least 8.5 Mbps for video? So, it is a little bit confusing what really is the usable DVD peak for replicated DVDs (DVD-5 or DVD-9)? Is it ok in my project to use 8.6Mbps for video if it fits the 9.6Mbps or what ever is the exact scope?

HI David - if going to replication on DLT then you can max out the bit rate if you wish to... however you need to think about whether you need to.
There is a law of diminishing returns here - anything above about 8mbps and I doubt anyone except a well trained 'eye' could see any difference in the quality. All you'll be doing is increasing the file size. Also, it's worth remembering that there are still players which have trouble reading higher rates off a replicated disc (check the DVD FAQ - section 1.41 makes for interesting reading, although not all of these are down to high bit rates, of course).
I tend to encode at various rates with short samples of material and look for the differences. Where I can't see any, I opt for the lower rate. So far this has served me well!
Don't forget that a duplicated disc is using a very different material for the reflective layer and it is far less reflective than a replicated disc. This is largely why you need to keep the duplicated disc bit rate low - players struggle to read the higher bit rates from the less reflective surface and so stutter on playback.
Personally, if you can't see any difference between 7mbps and 9.8mbps I'd advise staying at 7. If there is a difference for your footage then try again with 8mbps, but don't be lulled into a false sense of security over the fact that a replicated disc should be able to have 10.08mbps combined bitrate... the quality of the player is really the issue. Whilst most will, some won't, though all should!

Encode Rates For Replicated DVD

We're about to send off a master DVD-R to replicate a DVD.
I've been told, but can't confirm, that I can go sky high on my video encode rates for replicated DVDs.
That's the opposite of what I've read for duplicating DVDs.
Any of those out there confirm that I can go to 8 or 9 mbps for an under 1 hour DVD with Dolby2 audio?
Or should I stay at 7.0 as I've always done.
thanks

Exception - Doubt in Finally

i have doubt in finally block..
we know, the finally block statements execute whether the
exception raises in try block or not..
but in my program the print statement working after try block
without using finally block..
pls anyone expalin about this very clearly..
for example:
class excep{
     static void demo(){
          try{
               int i=1/0;
               System.out.println(i);
          }catch(ArithmeticException e){
               System.out.println(e.getMessage());
          System.out.println("Executing Finally");
     public static void main(String ar[]){
          demo();
output:
/ by zero
Executing Finally
thanks

Hi
If in your catch block you would have thrown a new exception or the same exception that you got, then the system.out.println wouldn't have been executed. Only if it would have been inside a finally block.
So:
class excep{
static void demo(){
try{
int i=1/0;
System.out.println(i);
}catch(ArithmeticException e){
throw new Exception();
System.out.println("Executing Finally");
public static void main(String ar[]){
demo();
you wouldn't get "Executing Finally" on the console.
but:
class excep{
static void demo(){
try{
int i=1/0;
System.out.println(i);
}catch(ArithmeticException e){
throw new Exception();
finally {
System.out.println("Executing Finally");
public static void main(String ar[]){
demo();
"Exceuting Finally" would be printed to the console.

         } catch(NullPointerException e) {
           System.out.println("Caught inside demoproc.");
           throw e; // rethrow the exception
       public static void main(String args[]) {
         try {
           demoproc();
         } catch(NullPointerException e) {
           System.out.println("Recaught: " + e);
}Output
Caught inside demoproc.
Recaught: java.lang.NullPointerException: demo
2)
public class Thrwodemo {
      * @param args
     static void demoproc() {
         try {
           throw new IllegalAccessException("demo");
         } catch(IllegalAccessException e) {
           System.out.println("Caught inside demoproc.");
           throw e; // rethrow the exception
       public static void main(String args[]) {
         try {
           demoproc();
         } catch(IllegalAccessException e) {
           System.out.println("Recaught: " + e);
}Compilation error
Unreachable catch block for IllegalAccessException. This exception is never thrown from the try statement body
First one compiles fine and gives the output but the second one gives the compilation error. Can someone please explain where i am going wrong? Both the programs are same except the exception thrown.

oh!! yeah sure..
The reason is NullPointerException is an unchecked exception and IlleagalAccessException is a checked exception. that's why NullPointerException doesn't require the throws stament where as IllegalAccessException do..
Thank you!!

Doubt on try/catch exception object

why it is not advisable to catch type exception in try catch block. Its confusing me. If i catch exception object then it will show whatever exception occured.
btw, i was just go through duke stars how it works and saw this
http://developers.sun.com/forums/top_10.jsp
Congrats!

Because there are many different kinds of Exception. If you have some specific local strategy for dealing with a particular excepion then you should be using a specific catch block.
If you don't then you should allow the expection to end the program, and ideally you should deal with all the expceptions in one top-level handler, so you should throw, rather than catch the exceptions in your methods. Often at the outer most level of the program or thread you will actually catch Throwable (not just Exception) to deal with any unanticipated problems in a general kind of way.
Also, you should be keeping track of what exceptions might be thrown, so that rather than using Exception in a throws clause or catch block, you should use the particular exceptions. Exceptions, generally, indicate a recoverable error that you really ought to be recovering from rather than just printing a stacktrace.
That's why exceptions are treated differently from runtime errors.
