Problem with GO_BLOCK

I have a procedure where I initialize some globals variables. In an other procedure, first, I display the content of one of my globals variables and I can see it. Second, I call the GO_BLOCK built_in and after, I display again the content of the same global variable but it is empty !!! What was happening ?

Maybe some code in a When-New-Bloc-Instance, When-New-Record-Instance, When-new-Item-Instance ?
Open the PL/SQL search dialog box, enter your GLOBAL name and search into your module.

  • Problem with set_item_instance_property and set_lov_property

    Hello guys,
    I am using oracle forms 6i and new to it. I am having a multi data block.
    I am facing a problem when I try to set the item instance property with respect to the list type.
    1) Basically, I am having a list item having three types MANUAL, INVOICE and BOE. All are independent of each other. I am facing the problem with the MANUAL type.
    I have written this code on When-Validate-Trigger of the list item as well as When-List-Changed. Also I am not setting the properties of any items initially(neither on When-New-Form-Instance nor on When-New-Block-Instance).
    if block.doc_type = 'MANUAL' then
    set_item_instance_property('BLOCK.VENDOR_NO', to_number(:system.cursor_record), REQUIRED,PROPERTY_TRUE);
    end if;
    But I am getting this warning/error frm 41383 - no such property for set_item_instance_property on both the triggers for the first time when I open the form and thereafter. During the same form session, if I click on the next line it shows a message Field cannot be empty and directs to the item where I compulsory need to insert a value. I also tried using to_number(:system.trigger_record) but getting the same issue. There are many more items I need to set the same property for.
    2)The invoice item on the block/form has a LOV. Another requirement is when I select 'MANUAL' , that LOV should not appear on selection of 'MANUAL' type and the user should be able to insert the value manually and validate manually. I did use set_lov_property, but did not get the correct usage. Please assist as soon as you can.

    Just out of my interest I would like to know what you exactly meant by "The :SYSTEM.CURSOR_RECORD reflects where the navigation cursor is; which could be different from the record that is initiating the event." in your reply.If you look at the Forms Help for both objects, you will see that...
    SYSTEM.CURSOR_RECORD represents the number of the record where the cursor is located. This number represents the record's current physical order in the block's list of records. The value is always a character string.
    SYSTEM.TRIGGER_RECORD represents the number of the record that Form Builder is processing. This number represents the record's current physical order in the block's list of records. The value is always a character string. Through PL/SQL you can send (using the GO_ITEM, GO_BLOCK and GO_RECORD built-ins) the interenal Forms Cursor to a different item, block or record within the current block. If, you GO to a different block or record in the same body of code and you then evaluated the :SYSTEM.CURSOR_RECORD and compared it with the :SYSTEM.TRIGGER_RECORD you would find that they are generally different.
    2) In response to the second one, do you want to say that when it I select MANUAL I do not use the set_item_property OR use this property and attach an LOV which does not return anything OR use this property, give the name of the same of the same LOV,I am using and set PROPERTY_FALSE. First a litte back ground. When an Item has an LOV assigned to it, Oracle Forms automatically displays what it calls the "LOV List Lamp" in the status bar. With Forms 9i and higher, it displays and "List of Valu..." in the status bar when an item has an LOV assigned to it. Items can have an LOV assigned during design-time or during run-time. You cannot, however, unassign an LOV during Run-time becuase the SET_ITEM_PROPERTY built-in requires you to pass a valid LOV object name.
    Well, as I was writing this, it occured to me that you will not be able to set the LOV assigned to your multi-row item at run-time either because once you assign an LOV to an item in a multi-row block, all occurances of the Item will have the LOV assigned. This being the case, I would recommend using a button and give it the appearance of enabled or disabled by using the VISUAL_ATTRIBUTE property and add code to the button so that if the row status is MANUAL then nothing happens. Using this method, you would create two Visual Attribute (VA) objects; ENABLED and DISABLED. The ENABLED VA would make the button look like a normal button while the DISABLED VA would make the button look like it is disabled (grey out button text, etc).
    I would also like to know when to use set_lov_property and if you could explain in brief with an example.The only time I have used the SET_LOV_PROPERTY() built-in is when I needed to change the Record Group query assigned to the LOV. We have a form where depending on the "Action" selected, the LOV for a certain item needed to change. The values returned by the LOV were still assigned to the same block items, so rather than create multiple LOVs and set the Column Mapping for each LOV, I just create a Record Group object for each action and then used the SET_LOV_PROPERTY() built-in to change the LOV TITLE and GROUP_NAME. This way, I was able to reuse the LOV and it's existing column mappings while changing the record group that provided the data for the LOV.
    The problem lies when I am entering the fields after the invoice number. The fields before the invoice no including the field of invoice no hold the value entered but when I click/press a tab key to go on to the next field the values in the earlier fields(i.e fields before invoice no and invoice no field) disappear i.e. the values do not hold their place and again prompts me from start to enter the vendor no.Are you navigating to a new row/record? That could explain the disappearing data. If not, then I would look for a trigger on the item you're navigating too or for a Block level When-New-Item-Instance trigger that has code that sets the items to null. It sounds like something in the design is causing the field values to disappear (get set to NULL) so I would look at what happens in your form when a navigation event occurs.
    @Andreas - actually, REQUIRED is a valid property for the Set-Item-Instance-Property() built-in. ;)
    Hope this helps,
    Craig...

  • Problem with "SELECT...FOR UPDATE OF..." and "POST command" combination

    Problem with "SELECT...FOR UPDATE OF..." and "POST command" combination
    Problem in committing transactions in Multiple Forms (Oracle Forms) with POST built-in command:
    Consider that the following statements are written in WHEN-WINDOW-CLOSED trigger of a called form.
    Statements in called form (Form name: FORM_CHILD):
    go_block('display_block') ;
    do_key('execute_query') ;
    -- Data from table_b will be populated in this block, based on the value of COLUMN_1 obtained
    -- from TABLE_A.
    -- Example: If the value of COLUMN_1 is 10, then all the matching records from TABLE_B, which
    -- are inserted with value 10 in TABLE_B.COLUMN_1 will be fetched and shown here.
    if user_choice = 'YES' then
    commit ;
    else
    rollback ;
    end if ;
    Statements in calling forms:
    There are two calling forms having following statements and it is going to call the above said called form.
    CALLING FORM 1
    Statements in KEY-COMMIT trigger:
    post;
    call_form(form_child, no_activate) ;
    Statements in ON-INSERT trigger:
    select column_1
    from table_a
    for update of column_1
    where column_2 = 'X' ;
    update table_a
    set column_1 = column_1 + 1
    where column_2 = 'X' ;
    insert into table_b ...;
    insert into table_b ...; Statements in KEY-COMMIT trigger:
    post;
    call_form(form_child, no_activate) ;
    CALLING FORM 2:
    Statements in ON-INSERT trigger:
    select column_1
    from table_a
    for update of column_1
    where column_2 = 'X' ;
    update table_a
    set column_1 = column_1 + 1
    where column_2 = 'X' ;
    insert into table_b ...;
    insert into table_b ...;
    insert into table_b ...;
    Our understanding:
    Assume that both the forms are running from two different machines/instances, issuing commit at the same time. In this case, forms will start executing the statements written in ON-INSERT trigger, the moment POST command is executed. Though the commit is issued at the same time, according to oracle, only one of the request will be taken for processing first. Assume that calling form 1 is getting processed first.
    So, it fetches the value available in COLUMN_1 of TABLE_A and locks the row from further select, update, etc. as SELECT...FOR UPDATE command is used (note that NOWAIT is not given, hence the lock will be released only when COMMIT or ROLLBACK happens) and proceed executing further INSERT statements. Because of the lock provided by the SELECT...FOR UPDATE command, the statements in calling form 2 will wait for the resource.
    After executing the INSERT statements, the FORM_CHILD is called. The rows inserted in to TABLE_A will be queried and shown. The database changes will be committed when user closes the window (as COMMIT is issued in its WHEN-WINDOW-CLOSED trigger). Then the SELECT...FOR UPDATE lock will be released and calling form 2's statements will be executed.
    Actual happenings or Mis-behavior:
    Calling form 2 starts executing INSERT statements instead of waiting for SELECT...FOR UPDATE lock. Also, the value selected from TABLE_A.COLUMN_1 is same in both the calling forms, which is wrong.
    The rows inserted into TABLE_B are having similar COLUMN_1 values in calling form 2 and they are fetched and shown in the called form FORM_CHILD.
    Note that in calling form 2 also POST only is issued, but the changes posted there are accessible in calling form 1 also, which is wrong.
    Kindly suggest us as to how to fix above problem. It will be much use, if you can send us the information regarding the behavior of Oracle Forms POST built-in also.
    Our mail ID: [email protected]
    Thanks a lot in advance.

    You have several problems:
    1. On-Insert will ONLY run if you have created a new record in a base-table block. If you haven't done that, then the POST command will not cause it to run.
    2. Select for update without a "no wait" will lock records for the first form, but when the second form tries this, it will hit the ORA-00054 exception, and will NOT wait. The only way you could make it wait is to issue an UPDATE sql command, which is not such a good way to go.
    All POST does is issues SQL insert or update commands for any changes the user has made to records in a form's base-table blocks, without following with a Commit command.
    Also understand that Commit is the same as Commit_Form, and Rollback is the same as Clear_Form. You should read up on these in the Forms help topics.

  • Problem with libclntsh.so on Tru64

    Hello,
    We are developping a C application using OCI 7.3 Data access fonctions on Unix servers.
    One of our clients is using an Alphaserver with Tru64 5.1 and an Oracle 8.1.7 database. Our application used to work correctly on this server. But recently, this client installed a patch kit (t64v51b19as0005-20020411) from Compaq (who asked for it for some supports reasons), and since that our application doesn't work at all.
    When we launch the application, the following message immediatly occurs:
    Illegal instruction(coredump)
    After some deeper tests, it appeared the problem is coming from the library libclntsh.so which seems to be non-compatible with the new kernel (the problem occurs only when the library is linked with the application). We tried to regerate this library with gennfgt and genclntsh, but the problem remains the same. Does anyone already met this problem ? And then, what is the solution, how can we make the libclntsh.so compatible with the new kernel ?
    Thank you for any help

    If you're talking about the "so called" calendar Lov implemented using forms-objects (blocks etc.), you will have the problem with required items, for the the calendar will issue a GO_BLOCK which causes validation to happen, which will fail on the require item.
    Solution?
    If you're on 10G, theres also an example with a java-bean.
    If on 6i, you could create a standalone form implementing the calendar-lov-functionality and do a call_form instead of a GO_BLOCK.

  • 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())){

                    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)

    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

  • Problem with threads and/or memory

    I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
    (note: eache thread is in execution using a finite state machine)

    i had been running the program inside Netbeans.
    Running the jar using the command line outside
    Netbeans i have no more problems... Does Netbeans use
    it's own JVM?Depends how you set it up, but look under the options. There are settings for the compiler and jvm that it uses.

  • Installation problem with NW'04 SR1: database connection failed

    Hi all,
    while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
    com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
    The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
    Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had
    Below I attached the sapinst.log and jload.log with more detailed messages.

  • Problem with item and/or data during page-processing-PS/SQL

    Greetings!
    On my page I have a custom report (from 2 tables) and a small form-field, that adds and edits data in the report. After generating the form with the wizard I added an extra item, to store the id from one of the tables from the report data.
    Now, on submit a calculation should take place, that updates data according user input with a procedure in Page-Prosseses:
    declare a number;
    begin
    case :PLATZ
    when 1 then a:=100;
    when 2 then a:= 50;
    else a:=25;
    end case;
    update TBL_MITGLIEDER set TURNIERPUNKTE = TURNIERPUNKTE + a
    where ID_MITGL = :P14_ID_MITGL;
    end;
    :PLATZ is user selected (1,2,3), :P14_ID_MITGL stores the reference to TBL_MITGLIEDER (and shows the change, when I select another record)
    As I understand, that process should also run, when I submit a chance, but nothing happens then.
    But when I try to save a new record (which worked without any problems before adding that process), I get this error message:
    ORA-06550: line 1, column 64: PL/SQL: ORA-00957: duplicate column name ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
         Error      Unable to process row of table TBL_TURNIERSIEGER.
    Then, when I go back into the app-builder and try to run the page again, I get this message:
    ORA-01403: no data found
         Error      Unable to fetch row.
    I am not sure, if you guys have all the information you need, to know whats going on. Maybe this has to do with session-id and the whay, items are updated. I hope you can help me.
    Thanks, best regards,
    tobi

    First can you please post all log file errors
    >> I can't really give you a solution or specific recommendation since I did not saw this error yet myself, but on your own risk you can try:
    1. You may try to just register 'dts.dll' using regsvr32.exe, but this error may indicate a bigger problem with setup.
    If you are running SQL Server 64bit then try running this at the command prompt: %windir%\syswow64\regsvr32 "%ProgramFiles(x86)%\Microsoft SQL Server\90\dts\binn\dts.dll"
    2. You can try reinstall from start (In this case you have to make sure that you un-install all)

    Hi,
    Here is my /var/log/messages.log output.
    Since several days my computer repeatedly restarts programs that require at least a bit memory, such as firefox ('segmentation fault'), skype, virtualbox, generaly gnome 3 environment. Sometimes it happens that the system hangs and I can't do nothing, although I can hear that hard disk is working - at that moment only hard reset helps.
    I know that the Dell Inspiron laptops (1720) have problems with Nvidia 8600M GT (the cold solder). Is it like that this time? Or maybe something wrong with the memory, CPU (Core Duo) cache memory?
    I will be happy to add any additional information.
    Regards,
    Lukasz
