Hello Guys I have a problem that I can not get to the bottom.
Time Machine has suddenly stopped working it really slow to make up. Copy a few kb at a time and long hours it takes to close the back. (up to a few tens of megs, 10, 20 Mb).
I made the following list of tests that will follow along with the log file.
First of all I made a copy as root with Carbon Copy Cloner disk of the iMac. (So that they can go back in case of disaster)
Following the guides Pondini (pondini.org) I did the following steps:
1) Changed the internfaccia FW800 to USB hard drive (does not change anything, still slow)
2) Changed to another external HD for time machine with FW800 and USB (nothing changes still slow)
3) Recreated the full backup with Time Machine on either drive (still slow)
4) Reinstalled the 10.6.8 Combo Pack (still slow)
5) Re spootlight indexed with the disk (still slow)
6) At this point, in desperation I reinstalled on the internal drive of my iMac 10.6.8 creating a new user, User Migration Assistant from my hd clone with Carbon Copy Cloner. Recreated the full backup with Time Machine.
The first full backup is fast, but slow incremental backups are back (as to 'start a few kb at a time).
I compared the log files with those of my other machine with same configuration and I found these errors:
backupdir [19376]: CFPropertyListCreateFromXMLData (): Old-style plist parser: missing semicolon in dictionary.
mdworker32 [20950]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint () to catch errors logged as They Are.
You know help me? I saw that this error is from 10.5 to 10.7, but no one has found a real solution to the issue.
I never installed antivirus software and tried with different external drives COPN capacity equal to or greater than the external drive. Only at the end I tried to divide the external drive to back up into two parts by a 1.5 TB and 500 GB but with the same mistakes that I have described.
thanks

Ciao Ragazzi ho un problema a cui non riesco a venire a capo.
improvvisamente time machine ha smesso di funzionare va veramente lento a fare backup. Copia pochi kb alla volta e impiega tanto tempo ore per chiudere il backup. (backup di poche decine di mega, 10, 20 Mb).
Ho effettuato le seguenti prove che vi elenco di seguito insieme al file log.
Prima di tutto ho fatto una copia come utente root con Carbon Copy cloner del disco del imac.(in maniera tale di poter tornare indietro in caso di disastro)
Seguendo le guide di Pondini (pondini.org) ho effettuato i seguenti passaggi:
1) Cambiato internfaccia del disco rigido da FW800 a USB (non cambia nulla, sempre lento)
2) Cambiato hd esterno con un altro per time machine con FW800 e USB (non cambia nulla sempre lento)
3) Ricreato il full Backup con time machine su entrambe i dischi (sempre lento)
4) Reinstallato il Combo pack 10.6.8 (sempre lento)
5) Re indicizzato con spootlight il disco (sempre lento)
6) A questo punto preso dalla disperazione ho reinstallato sul disco interno del mio imac il 10.6.8 creando un nuovo utente, Assistente migrazione utente dal mio hd clonato con Carbon copy cloner. Ricreato il backup completo con time machine.
Il primo full backup è veloce, ma i backup incrementali sono tornati lentissimi (come all' inizio pochi kb alla volta).
Ho confrontato il file log con quelli di un mio altro mac con la stessa configurazione ed ho trovato questi errori:
backupd[19376]: CFPropertyListCreateFromXMLData(): Old-style plist parser: missing semicolon in dictionary.
mdworker32[20950]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
Sapete darmi aiuto? Ho visto che questo errore è presente dal 10.5 al 10.7 ma nessuno ha trovato una vera soluzione alla questione.
Non ho mai installato software antivirus ed ho provato con diversi dischi esterni copn capacità uguale o superiore al disco esterno. Solo alla fine ho provato a dividere il disco esterno del backup in due parti una da 1,5TB e una da 500 Gb ma con i medesimi errori che vi ho descritto.
grazie
Stefano

I followed the steps you listed and also remove the files that were creating problems spootlight, including the audio plugin and the panel preferences file.
Then I stopped by the timemachine reindexed spootlight 'option in the preferences panel spootight privacy. After I restarted my iMac and formatted the external drive again, Time Machine and restarting a full backup. This morning after a quick full backup and disk indexing completed incremental backups are always slow. Proceeds with a few kb at a time. I resend you the log files and screen capture. My iMac is constantly backed up.
Thank you for your time.

How do we catch errors in Servlets?
Hello, i 'm using Servlets and JDBC.
i'm having a form.html where the user inserts data in the input fields.
It's a registration page.
I would like to check for possible user errors.
For example if the user has not typed anything in a required field like field "password", so the field is null.
I would like to inform the user that this field is null and he/she shall type in it again.
(I'm talking generally not only for a registration page but to any page that requires correct data)
*1.* Shall i use Javascript?
*2.* Shall i direct the user to an error page where the page describes the error, what the user has to do in order to correct it and direct him back to the previous page?
*3.* Shall i only use if/else?
I would appreciate if sm could give me some advice on this matter or post me some links related to catch errors in servlets.
Thanks, in advance!
Edited by: g_p_java on Jul 11, 2009 12:15 PMHere is a possible approach to this issue:
* use javascript to validate all textfields on the form client-side every time the user clicks the submit button. If it fails, put a message in red next to the problem textfield describing what the problem is. Dont allow submit if there are validation issues.
* More than one validation may apply to a given textfield. For instance, the field cant be empty is checked before its checked for an invalid date.
* Check to see if its an invalid date format first (example: mm/dd/yyyy), then check to see if its an invalid date (non leap year for example).
* recheck all validation back on the server (necessary if user disabled javascript or a hacker bypasses your client side validation). Redraw the page and populate it, but put messages next to the problem fields as you did for javascript.
* The invalid date format and invalid date should pass if given an empty value since the its the empty value validation (if it applicable for that field) that is repsonsible for that test.
*since you will be applying this validation over and over again for all your JSP pages for this project and future projects, it may be a good idea to create reusable code for it. You may also research google for good approaches.
Your javascript code should be from a single javascript file that is included into each JSP page so it can be reused.
@see http://www.xs4all.nl/~sbpoley/webmatters/formval.html
* All textfields should be validated throughly so your database never gets bad data (data is king).

invalid date format, invalid date, empty textfield, invalid email address, invalid telephone number format, invalid zip code, etc, etc, etc -
Problem in catching UserException
I have a problem in catching UserException in the JavaCard RMI demo of purse client from the Development Kit. The error that i'm getting is this, instead of catching the UserException:

Update: I'm using JDK 1.6 and I already have tried 1.5, and still have this problem. Also, I get this problem by running either CREF and JCWDE.
It seems that when the runtime environment calls getCurrentContext() from the NativeMethods class it gives an error. The application runs well, and this only happens when a UserException is thrown by the card. All the samples in the javacard kit 2.2.2 gives this problem when the card throws an UserException. Please I need help on this problem, I can't find a solution anywhere...
Thanks in advance.

I'm using Eclipse for the development of JavaCard applets and the host side. So, i had all the librabries from the JavaCard Kit all along in the same project. When the client application tried to catch an exception thrown by the card some conflicts surged.
To fix this,if you're using Eclipse for the development, you have to separate the necessary libraries for the card from those necessary for the host applications. Now I have two projects, one for the client applications and another for the card side. -
More trouble with registering sapccmsr and EYE CATCH error
Hello all,
I saw that this was a topic in an earlier thread. That thread was very helpful for troubleshooting, but it seems I have everything properly set up and patched, but I am still receiving the dreaded EYE CATCH error. The system is a Unicode dual-stack XI system. Here are the details:
sapccm4x registers with no problems.

Anyone have any ideas why I am unable to register the sapccmsr? Thanks in advance for your help.
Best Regards,
Warren ChirhartHi,
I'd just like to make some additional comments.
The issue comes from the "jmon.dll" library which is non-unicode. You have to download the latest SAR archive of the SAP CCMS agents from the Service Marketplace and update your agents as well as your "jmon.dll" library by replacing the EXE and DLL files.
The agent files are located under:
/usr/sap/<SID>/<INSTNACE>/exe
The "jmon.dll" library is located under:
/usr/sap/<SID>/<INSTNACE>/j2ee/os_libs
Most probably you would have to shut down / restart the instance after you update the library so the changes take effect.
You can find the latest SAP CCMS agents SAR archive in SMP under:
https://websmp109.sap-ag.de/swdc
Then browse to:
/SAP Support Packages/SAP Support Packages and Patches/Entry by Application Group/SAP NetWeaver/SAP NETWEAVER/SAP NETWEAVER <version>/Entry by Component/Application Server ABAP/SAP KERNEL <version> <32-BIT | 64-BIT> UNICODE/<OS>/#Database independent/ccmagent_<agent_version>.sar
Hope this helps.
Kind regards,
Rosen -
Catching Errors: opinions needed
Under what conditions should a program try to catch Errors (not Exceptions) ? The docs for the Error class read:
"An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch."
However, nothing enforces the fact that I should not try to catch an Error. I can catch a StackOverFlowError, ExceptionInInitializerError, etc. just as I would catch any Exception class.
Everything I have read talks plenty about Exception handling, but basically nothing about Error handling.
My questions are: 1) Why doesn't the JVM prevent me from catching Errors? 2) Under what conditions should I try to catch Errors? 3) What are good practices for handling Errors?My questions are: 1) Why doesn't the JVM prevent me from catching Errors? In case you need to catch them.
2) Under what conditions should I try to catch Errors?When you want to perform an action when a specific error occurs.
An action I perform is to shutdown my server when an OutOfMemoryError or StackOverflowError occurs. This is required as an Error only results in the end of the thread which threw it. The other threads can keep running, leaving a running but unless application, like a zombie. Under this condition, if the application is not working it should shutdown. e.g. System.exit();
3) What are good practices for handling Errors?When you catch an erro you should rethrow it. (I don't always, but this is considered good practice) -

Catching errors in web services
I have a web service that I am adding error handling to log
and notify me of anything that I haven't already caught with
specific cftry/catches. I put an onError function in my
application.cfc. When I test my error handling by calling the .cfc
as a component from a .cfm template, it works great. The onError
logs the error and sends me an email.
When I test using a .Net app and call the .cfc as a web
service, something besides my onError seems to catch the error. It
returns "coldfusion.xml.rpc.CFCInvocationException:
[coldfusion.runtime.UndefinedVariableException : Variable apple is
undefined.]" (My test is trying to add 1 to apple (which is not
defined) ).
Whatever this mysterious handler is correctly identifies the
error. But, it is not calling my routines to log and email me.
Anyone have a clue how to catch errors in web services???
Thanks,
MikeHi mferris,
Looks like I'm facing the same exact situation trying to use onError() method in a webservice:

Try/catching errors occuring in synchronous event handlers
Hi,
I know that using try/catch in flash player it is possible to catch only synchronous errors, but recently I ran into code in our application which I strongly believe is synchronous but it behaves as if it wasn't.
In example below I create event listener and inside try/catch I dispatch event. Handler function throws error. Executing code stops when error is thrown, so message "after throwing error" won't be logged, but try/catch block catches nothing and code executes as if nothing happened after event dispatch.
Dispatching event on element executes handler method immediately so it is synchronous execution. Event call stack which is displayed in debug versions of flash player, shows every function from creation of class to execution of handler.
Generally flash applications relays heavily on events and in my case it caused ours users projects to be irreversibly corrupted, because of this continuing to work after error, which I even can't properly detect and handle, cause it's going throught 5 or more event handlers and adding try/catch to each handler would create enormous chaos in my code. So my question is why does flash player behaves like this? Are there any ways to tell compiled SWF file to treat such cases as synchronous calls, f.e. compilation parameters?
package
import flash.display.Sprite;
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.text.TextField;
public class TestApp extends Sprite
public var cTextField:TextField;
public function TestApp()
cTextField = new TextField();
cTextField.width = 300;
cTextField.height = 200;
addChild(cTextField);
onAppCreated();
protected function onAppCreated():void
var eventName:String = "my_event";
var caughtError:Boolean = false;
var dispatcher:EventDispatcher = new EventDispatcher();
dispatcher.addEventListener(eventName, handler);
try
dispatcher.dispatchEvent(new Event(eventName));
} catch (error:Error)
caughtError = true;
cTextField.text += caughtError ? "caught error\n" : "error wasn't caught\n";
protected function handler(event:Event):void
cTextField.text += "before throwing error\n";
throw new Error("throw error");
cTextField.text += "after throwing error\n";Okay, nobody bit. Sorry.
The only way to really figure out what is going on is to look at a running example with a C++ debugger. I'm particularly curious about whether this problem happens in a specific browser/os combination (we may be working around a quirk of that platform), or if it's something that happens everywhere.
The most effective way to proceed is going to be to file a bug with a simplified, executable example (source and compiled SWF, ideally) that demonstrates the problem. This will help me route the bug to a developer and get you an answer in the shortest time possible.
You can file a bug here:
http://bugbase.adobe.com/
If you reply here with the bug number, I'll get it assigned to an engineer.

Hi Fellows,
Since a couple of days I can't upload images and pdf's to my wiki anymore. What happens is that the image or pdf gets uploaded once and processed 3 or 4 times (I can find them in the corresponding /Library/Collaboration/ folder). But the image or pdf does not show up in the wikipage and throws up a server error message instead: There was an error uploading the file. Please try again.
Stop/Start the wikid proces solves the problem shortly until after a couple of hours the problems start occuring again.
On the server side I see this:
Oct 10 08:08:37 myserver com.apple.wikid[41152]: Wed Oct 10 08:08:37 myserver.x.net QTKitServer[45631] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

"Problem When Printing" error on Mac Mini
Hi all,
I just recently updated my Mac Mini from 10.3 to 10.4. Instead of Archive and Install I formatted and did a clean install.
I have my printer set up, however whenever I try and print anything from any application I get a very unhelpful "Problem when printing" error, and nothing prints.
I also get the same error when trying to save to PDF.
My printer is a HP Deskjet 3750, and the driver is the one included with 10.4 (as per HP's instruction), but I don't think it's a driver problem as Save to PDF gives me the same error.
I've already tried repairing permissions. Anyone know what could be causing this. Any help is greatly appreciated.
Thanks.Bugger. PSR is often a winner
You could try installing Gutenprint 5.0.1 available from Sourceforge (it's about 15MB). It's an updated version of the included GIMP-Print drivers and may repair/replace/install some of the core files. Otherwise you may have to contact Apple and see if you can get 10.4.9 mailed to you. -
I'm working with 11g.
I have a BPM process and I want catch the system errors to redirect the work flow at a subprocess or in the particular form that can help external users
I have tried with "evant subprocess" but don't work (BUG fix in only for PS5(11.1.1.6 version) )
Can you help me?
Thanks
ElenaCan you be more specific about the bug?
It's true that the fault handling framework for recovery (as in BPEL) is in an upcoming release. But you can (in 11.1.1.4) put the activities that would generate errors in an embedded subprocess, then put a boundary catch event on the subprocess to catch and handle system and/or business errors. The flow out of whatever handles the error can rejoin the main flow or loop back to retry. A common pattern is to have to flow go to a human activity where the outcome of the activity determines whether to retry.
You can also catch error events in an event subprocess, but you can't continue the main flow from there. That flow (within the event subprocess) either interrupts or is concurrent with the main flow. -
Catching error in call transaction
Hi,
Can anyone tell me how to catch errors in call transaction method.
Please provide step by step guide.
Thanks,
ShipraHi Shipra...
This is the way...
data : It_MSG type table of BDCMSGCOLL with header line.
DATA : V_MESSAGE TYPE STRING.
LOOP AT ITAB.
PERFORM MAP_BDCDATA.
CALL Transaction 'MK01'
USING it_bdcdata
MODE 'N'
Messages into IT_MSG.
if sy-subrc ne 0. "when the Transaction is unsuccessful
**Display the Error messages
LOOP AT IT_MSG WHERE MSGTYP = 'E'.
CALL FUNCTION 'FORMAT_MESSAGE'
EXPORTING
msgtyp = it_msg-msgtyp
msgno = it_msg-msgnr
msgid = it_msg-msgid
msgv1 = it_msg-msgv1
msgv2 = it_msg-msgv2
IMPORTING
MESSAGE = V_MESSAGE.
WRITE:/ V_MESSAGE.
ENDLOOP.
REFRESH : IT_BDCDATA, IT_MSG.
ENDLOOP.

Catching errors such as divide by zero and typing non-numeric characters
Fellows: How do I extend following script to catch errors such as divide by zero and typing non-numeric characters. Thanks
This program takes two integers (whole numbers), then displays the sum, average, division,
Modula of those numbers and finally the first number raised to the power of the second number.
import java.io.*;
public class HWOne
public static void main(String[] args) throws IOException // error handling
// variable declaration
String firstdigit, seconddigit;
int first, second, sum, total, modus, power;
float division;
double average;
BufferedReader myIn = new BufferedReader(new InputStreamReader(System.in));
//Invoke user response
System.out.print("Please enter first digit ");
firstdigit = myIn.readLine();
first = Integer.parseInt(firstdigit);
System.out.print("Please enter second digit ");
seconddigit = myIn.readLine();
second = Integer.parseInt(seconddigit);
//computations
sum = first + second;
average = (double)sum / (double)2;
division = (float)first / (float)second;
modus = first % second;
power = (int)Math.pow(first, second);
//Screen message
System.out.println("Sum: " + sum);
System.out.println("Average: " + average);
System.out.println("Division: " + division);
System.out.println("Modula: " + modus);
System.out.println("Power: " + power);Have you learnt about try/catch statements yet?
The parseInt method throws a NumberFormatException. So you place the call to that method inside a try statement and catch the exception.
For divide by zero, you can use an if statement. If the divisor != 0 perform division.
