Problems with OCR and OracleCSService

Hi,
Sorry for my English, but I am not a native English speaker.
I installed Oracle 10g Release 1 on a Windows XP Pro SP1 System. So far everything
works fine, but already during the installation I got two error messages:
First the OCR (Oracle Cluster Registry) could not be initiated, later the
OracleCSService could not start.
Any ideas?
Thanks in advance
Jhonny

Are you trying to cluster your DB? I have read several posts that say you can't install the cluster services on XP because CRS won't run. I installed XE (Express Edition) on my XP laptop and didn't have a problem, but I wasn't trying to install CRS.
If you don't need CRS - I'd install XE instead.

Problem with advanced threshold in OCR - Vision Assistant 2013

I'm facing a problem with Vision Assistant 2013
The OCR charter set file advanced threshold data is always fixed at 255 upper value and optimize for speed is checked.
I edit them and reopen the file but no change.

Hi Paolo,
Thanks for your answer. Yeah I have seen the examples and I´m familiar with the use of the OCR VI. I have use it a couple of time already with good results.
My problem came last week. While I was trying to run OCR on my image in my LabVIEW code. The algorithm did not detected what I was expecting.
I decided to run the test on the vision assistant and it worked perfectly. I assumed my code had different parameters, so I decided to generate a VI from the vision asssistant and run it on LabVIEW for the same image to verify.
I did not change anything on the VI (all parameters are the same), and used the same image. Surprinsingly the results are different between the assistant and the VI. That strikes me a lot!
I´ll start a new thread as you recommended. Hope to find the solution soon. Thanks
Regards,
Esteban

Thoroughly frustrating problem with Preview

Hi,
I'm new to the forum and tried to hold out as long as possible, but the problem I'm having has so thoroughly frustrated me I had to post this. Let me try to be as clear as possible.
I have a Mac (OS 10.8.2, upgraded from a late-2009 Macbook running Snow Leopard - 2.26 GHz Intel Core 2 Duo, 4 gb RAM, 1067 MHz DDR3). I have Adobe Acrobat Pro XI installed. I also have Microsoft Office 2011. Both Acrobat, M. Office, and all my software is fully updated and current. I have no font conflicts, as I have just clean re-installed my OS because this problem is so frustrating.
The issue is with pdfs I make of books I own. Sometimes I will use my iphone 4 (latest iOS 6.1.2) with apps like "CamScanner+" or "GeniusScan+" to copy chapters and make pdfs. (CamScanner+ has built in OCR capability.) I then upload them to my WebDAV bibliography storage cloud on Box.net to access from my Mac laptop. Sometimes I use the University's big overhead scanner to make monochrome pdfs, and run OCR thru Acrobat Pro XI. Sometimes I will use the Canon scanners in the computer labs, and do OCR in Acrobat Pro XI then. In each case, I use Zotero to handle attaching pdfs to bib entries and sync it all up to my WebDAV account. (Zotero has a plugin I use called "Zotfile," which also allows one to extract notes, highlighting, annotations, etc., and store them on Zotero while also keeping them on the pdf.) In either case, though, I always run the pdf thru Acrobat Pro XI to optimize, at the least.
When I access the pdfs for notetaking, research, etc., I tend to use Mac's Preview built-in app. I find it easier to streamline, scroll, view and add notes, less clutery, etc. I see that this new Mountain Lion Preview is much different than Snow Leopard's, which is very regrettable. In this version, Preview saves as you go, it seems.
The problem is that everytime I save the pdf I've been working on from File>Save (and even when Preview saves as I go), it does a number of nasty, unwanted things. First, it somehow doubles the filesize (e.g., from 30mb to 67mb). Second, and MOST HATED, it takes the OCR'ed texts/fonts and converts them all to alien faces, square boxes, or just blanks. (God it's making me angry just thinking about it now - I've spent two full weeks now trying to fix this!!!!) This happens regardless of whether I ClearScan the OCR, Searchable text the OCR, or Searchable text (exact) the OCR. It happens regardless of whether the OCR'ed fonts are embedded, embedded subsets, etc. Every option on Acrobat Pro XI, I feel I have tried and exhausted and Preview still f$&#s it up. As far as I can tell, this happens regardless of what kind of font is used in the OCR'ed pdf (e.g., TrueType, CID, etc.). In every single instance, Preview will 1) double the file size and 2) screw up the fonts upon saving. If I take this newly ruined pdf back into Acrobat Pro, highlight text, copy and try to paste into Word, Chrome, or any other app it produces the same result. However, if I right click and "copy with formatting" from Acrobat Pro, it copies the actual words/font. The newly ruined Preview pdf doesn't return any word searches either. And annotations like highlighting, once extracted or even viewed in the notes&highlighting box, show blanks. I have downloaded and tried a Mac app called Skim, and it is the exact same effect, unless I File>Export...
I know this is not a problem with my Mac's fonts since I just did a clean re-install. Font Book tells me everything is alright too. This occurs regardless of what save settings I choose in Preview (e.g., the default settings, the quartz settings, reduce file size, etc.).
The strange part, though, is that when I take this newly ruined Preview'ed pdf, highlight text, go to font inspector, it says the highlighted font is exactly what it was when Acrobat saved it (e.g., Arial). And if I take this same document back to Acrobat and view properties, it says the fonts are the same as they were when Acrobat Pro originally processed it.
SO... I hope someone can help me with a fix for this. I truly do not want to use Acrobat Pro XI as my research pdf tool. It doesn't scroll smoothly, the layout is clunky, etc. It just isn't conducive to research/reading/notetaking. Preview, I think, is, and so I want to be able to have a fix for this so that Preview will quit ruining my life.
I can provide sample pdfs if that might help. I can provide the original Acrobat Pro XI processed pdfs, as well as the newly ruined Preview pdfs. BTW, I posted this in Adobe's forums as well.

I assume the answer by macjack would not apply in the case of Snow Leopard - Preview version 5.0.3 - but I have the same issue with OCR (not the constant autosave issue though) on my '10 MBP running osx 10.6.8 where suddenly maybe about a year ago 2 hugely annoying things changed in Preview.
As first poster stated (and he/she obviously knows a LOT more about this stuff than me) Preview stopped providing accurate search results with most pdf documents (some downloaded, some created from web, etc., no idea of common thread there).
I can NO LONGER COPY AND PASTE any text in any pdf opened in Preview to another application!! I used to have no problem copying pdf text from Preview to, say, text edit. Now it comes up weird boxes and dashes and no, font choice and/or conflict is not the issue.
I realize this thread is within the Mountain Lion community, and forgive me if I should start a new thread in some other area of this forum saying exactly what I have here, but I have searched and searched on this topic for months and this is the first thread I found which refers to these exact issues I'm enduring.
Any further advice or comments on the subject - or even constructive instructions if I should post elsewhere - would be greatly appreciated!

Acrobat X problem with ClearScan in Windows 7

Using Acrobat X (10.1.2) Standard on WIndows 7 Pro. I have been scanning documents with OCR set to 'Searchable text' for months. I like the ClearScan option better, but when I changed the scanning options to use it Windows reported 'Acrobat has stopped working' and shut it down.
It happened on page 2 of a B&W scan at 600 dpi, and on page 5 of a greyscale at 300 dpi. The B&W problem was completely reproduceable, I only tried the greyscale once.
I tried the B&W scan (three pages) using 'Searchable text', followed by Tools > Document processing > Optimise scanned PDF and chose ClearScan there, and it worked fine.
I don't see any comments on this, although there are Mac comments related to ClearScan in Acrobat 9.
Is this a known problem?
John Inkle

Ankit, thanks for replying.
I have a CanoScan 4400F.
To check it again I scanned some pages in B&W after changing the option to ClearScan using Configure Presets. After the second page had scanned and the progress windows showed “Initialising OCR” it crashed. Windows report was only that Adobe Acrobat had stopped working, no “Details” link to click. I searched around and did not find a crash log, just the information below. Windows did suggest a solution – that I get an update to Adobe Reader, however I do not have Adobe Reader installed!
I tried a second time, and it was fine for 3 pages but crashed on the fourth. These are multi-page scans – I click “Scan more pages”.
Using Windows 7 Pro (32-bit), fully up-to-date.

Trouble converting pdf to word document with ocr

I just tried converting a pdf to a word document. I've done this successfully before. I checked the box indicating I wanted character recognition in English. The conversion I received was only a picture of the pdf file. No OCR. What's wrong?

Thanks for your reply. My file is confidential, so I tried creating a similar file, 1 page long,that wasn't confidential. I found that Adobe easily converted the similar file using OCR.
My original confidential file is 20 pages long, with 5 columns on each page. I thought maybe its length was the problem, so I tried converting only one of the pages to Word and it worked with OCR recognition. There were many, many mistakes though. Also, it wasn't possible to copy and paste the columns into a new document. When I did that, the data reorganized itself into a list format with irregular formatting--as if I were pasting in text format. It seems like the OCR process only partially worked.
I thought that maybe enough of the conversion was accurate for me to be able to work with it. when I looked at it closely I realized it wouldn't be possible.
Unlike me, my colleague has the full version of Adobe. When she returns tomorrow (Thurs.), I will see if she is able to change any of the writing on the original document to make it non-confidential. If she can, I will include a screenshot.

Also you clusterware installation installs to an ORACLE_HOME.
Oracle does only make a differentiation, if it has to be clear, that you got a clusterware home and a database home.
Normally if a patch is referring to $ORACLE_HOME (and the patch can be used for clusterware & database), it just means the installation directory of the oracle software installed.

A problem with threads

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;
     public void run(){
          ss.setSoTimeout(90);
          while (active){
               try{
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing
     // interrupt thread
     public void deactivate(){
          active = false;
          // you gotta sleep for a time longer than the
          // accept() timeout to make sure that timeout is finished.
          try{
               sleep(91);
          }catch (InterruptedException ie){
          interrupt();
}

Problem with Threads and a static variable

I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
   protected static void Init(){
        objMainProcess = new Thread() {
            public void run() {
                while( objMainProcess == Thread.currentThread() ) {
                   GetState();
        objMainProcess.setDaemon( true );
        objMainProcess.start();
    public static void initStatusTimer(){
        if(objTimer == null)
             objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                public void actionPerformed( java.awt.event.ActionEvent evt){
                          SetState();
    private static void SetState(){
        if( objMainProcess == null ) return;
        synchronized( objMainProcess ) {
            bChanged = true;
            try{
                objMainProcess.notify();
            }catch( IllegalMonitorStateException e ) {}
    private static boolean GetState() {
        if( objMainProcess == null ) return false;
        synchronized( objMainProcess ) {
            if( bChanged) {
                SendMessage();
                bChanged = false;
                return true;
            try {
                objMainProcess.wait();
            }catch( InterruptedException e ) {}
            return false;
    }

Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,
B.D.

Problem with threads running javaw

Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.

troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.

Problem with threads and camera.

Hi everybody!
I've a problem with taking snapshot.
I would like to display a loading screen after it take snapshot ( sometimes i
have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
I was trying to use threads but i didn't succeed.
I made this code:
display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while((!performing.isShown()) && (backgroundCamera.isShown())){
                    Thread.yield();
                notifyAll();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    this.wait();
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);
        }).start();This code is sometimes showing performing screen but sometimes no.
I don't know why. In my opinion performing.isShown() method isn't working correctly.
Does anyone have some idea how to use threads here?

Hi,
I've finally managed to work this fine.
The code:
       Object o = new Object();
       display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while(!performing.isShown()){
                    Thread.yield();
               synchronized(o) {
                  o.notify();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    synchronized(o) {
                       o.wait(1);
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);
        }).start();

Problem with threads hanging

We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).
=============================================================================================

String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

Also when it's having this problem, the "VM Thread" is always using a lot of processor time. We did a couple of pstacks today while it was having this problem, and this thread was stuck in the ONMethodSweeper.sweep for over 15 minutes when we finally killed the server.
From the thread dump:
"VM Thread" prio=5 tid=0x000e2d20 nid=0x2 runnable

Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there. Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this.
We're using the following memory options:
-ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
-verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
Thanks!

Problem with threads and ProgressMonitor

Dear Friends:
I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
But I need deactivate the main class(the main class is the user interface) until the thread ends.
I use something like this:
LongTask myTask=new LongTask();
myTask.start();
myTask.join();
Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
What's wrong?

Is the dialog a modal dialog? This can block other UI updates.
In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating
