About AQ ADT example functionality

Hi, ALL !
There are some questions about AQ adapter functionality in ADT example.
Any comments are welcome.
Thus:
1)If I will enqueue 5 messages in my DB,one after another(loop inside), and I will enqueue them fast enough so BPEL process will still be processing the 1st message when other 4 will be already inserted into the queue. In which way
ADT process will handle them in parallel flow or one after another?
And how much ADT process copies will be completed 1 or 5 ?
2)Suppose, I executed dbms_aq.enqueue command in my DB.
After that, bpel process should be initiated.
Now, how I can test ADT BPEL process status inside my DB , without looking at bpel console? I want to know whether it is on-fly, completed, had an error or waiting for something.
I want to know it because I would like to do some PL/SQL actions after getting confirmation of successful (or not) completion of bpel process.
3) I would like my BPEL process at some point of execution to check whether it has an incoming message waiting to be processed or not. If it has that message ready I want BPEL process to process it, if not I want my BPEL process to continue execution without a waiting for that message. How can I do it?
4) Does an AQ adapter work in the same physical process as ADT process or is it a different physical process? I mean when BPEL process starts? Whether AQ adapter is a part of BPEL process and BPEL process is running all the time by circle asking AQ Adapter for message or is an AQ Adapter is a different process that spawns BPEL process every time it gets a message?
5) Suppose I place some activity element "Element_1" between the circle named Start of the control flow of process and Receive_1 element. When my "Eelement_1" will be executed? Will it be executed every time I get a message in Receive_1 element?

I followed the steps detailed in this forum: (We are on BPEL 10.1.2.0.2)

About auto power off function

Hello again guys,
long time no see ,since yesterday as far as I remember
Talking about Auto Power Off function , is there anyone that can tell us , it could be used on long terms - many days for example - as long as no one push the shutter or any button to wake the "beast" ?
This function completly shut down the camera or it's a kind of sleep function and some parts remain power supplied ?
Thanks,
Solved!
Go to Solution.

It's not completly shutdown. However, it should not cost too much power if any at all. I have it on for a week. Unless you turn on the GPS. With GPS turned on, even if you turn off the camera, it is still active.

In the Report,First call screen Then Using "write" output some information,That is ok. but In the GUI When I press back button that is standard button,it exit screen to program.
My question is how can i do When i press back button,the screen can be back forward first screen instand of exit screen to program. Thanks .

This problem is solution.I call screen using T-code and submit report In PAI,at last return to PAI.That is OK.

Hi,
You can define your own PF-STATUS and in that assign the function code for BACK button anything except 'BACK'.
The code would somewhat look like this:
SET PF-STATUS 'TEST'.
write : itab-col1,
itab-col2.
in the PF-STATUS 'TEST', assign the function code to BACK button as 'BCK'.
Now in your program you can use the event AT USER-COMMAND.
In this you can handle the functionality of BACK button.
Hope this helps.

Question about code corner Example#33: How-to open a Bounded Task Flow in a new Browser Tab

Hello All,
I am implementing example #33 in code corner series Oracle ADF Code Corner</title><meta name="Title" content="Oracle ADF Code Corner"><me…
Every thing is going fine, but there is a comment in the java code that I don't understand.
public void onLaunchForEdit(ActionEvent actionEvent) {
      //access the ADF binding layer and access the tree binding that
      //populates the table
        BindingContext bctx = BindingContext.getCurrent();
        BindingContainer bindings =
                               bctx.getCurrentBindingsEntry();

        //get the current selected row key from the iterator binding
        //referenced from the table binding (tree binding). Of course,
        //I could have used the iterator name directly in the binding
        //lookup, but looking up the tree binding instead allows to
        //change the tree binding iterator dependency to a later point
        //in time without breaking this functionality. Its all about
        //"weak" dependencies that give you flexibility when coding ADF
        String rwKeyString =
               model.getDCIteratorBinding().getCurrentRowKeyString();
        launchWindow(rwKeyString);
What does this comment mean?

Is this a contrast to this line of code?
JUCtrlHierBinding model =
               (JUCtrlHierBinding) bindings.get("DepartmentsView1");
I mean in this line of code we hard coded the tree binding name from the page Def? why getting the tree binding name is a best practice while getting the iterator name is not?

JUCtrlHierBinding model =

Yes, it's exactly this line of code the comment is referring to. If you look at the bindings of a page you see three parts: on the left he bindings, in the middle the executables and on the right side the data control. The statement
JUCtrlHierBinding model =
               (JUCtrlHierBinding) bindings.get("DepartmentsView1");
access the binding, the tree binding to get the data. if you use the iterator which named 'DepartmentsView1Iterator' you are accessing the executable, the iterator itself. The comment now tell you that if you access the data via the tree binding, that you can change the underlying iterator to point to different data. This you can do without the need to change the code in the been, whihc is good as you (or we all) tend to forget that we have code working on the iterator, so changing things in the bindings will break the application.

Question about cursors in a function and how to return the results

Hi all,
Some tech info:
I'm using Oracle 11G database and APEX 4.0.2.00.06
I use three cursors in a function. My function is called in an APEX standard report, like this by example:
SELECT fnc_exp(tab.arg1, tab,arg2) FROM table_exp tab;
My question is: how can I return the values calculated from my function to a standard APEX report? Before, this function was used like this by Oracle Forms to fetch the cursors in the right table columns:
open c_a;
fetch c_a into :loc.arg1;
close c_a;
open c_b;
fetch c_b into :loc.arg2, :loc.arg3, :loc.arg4, :loc.arg5;
close c_b;
Thanks for your advices!
Maybe my solution is not right, if you have better ideas, please suggest :)
PS: If you need more details, please ask which you need.

Hi,
I don't think you can do exactly like that in APEX.
Go for a pipelined function if you want the value be returned from the function.

Question about Java Sound example?

Hello,
I found this example AudioPlayer, when searching for an example of how to play .wav files in Java.
The code seems quite long, and wondered if anyone could advise if this is the best way to play a wav file?
And could anyone explain if the EXTERNAL_BUFFER_SIZE should allows be set to 128000;
Thank you
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
public class SimpleAudioPlayer
     private static final int     EXTERNAL_BUFFER_SIZE = 128000;
     public static void main(String[] args)
            We check that there is exactely one command-line
            argument.
            If not, we display the usage message and exit.
          if (args.length != 1)
               printUsageAndExit();
            Now, that we're shure there is an argument, we
            take it as the filename of the soundfile
            we want to play.
          String     strFilename = args[0];
          File     soundFile = new File(strFilename);
            We have to read in the sound file.
          AudioInputStream     audioInputStream = null;
          try
               audioInputStream = AudioSystem.getAudioInputStream(soundFile);
          catch (Exception e)
                 In case of an exception, we dump the exception
                 including the stack trace to the console output.
                 Then, we exit the program.
               e.printStackTrace();
               System.exit(1);
            From the AudioInputStream, i.e. from the sound file,
            we fetch information about the format of the
            audio data.
            These information include the sampling frequency,
            the number of
            channels and the size of the samples.
            These information
            are needed to ask Java Sound for a suitable output line
            for this audio file.
          AudioFormat     audioFormat = audioInputStream.getFormat();
            Asking for a line is a rather tricky thing.
            We have to construct an Info object that specifies
            the desired properties for the line.
            First, we have to say which kind of line we want. The
            possibilities are: SourceDataLine (for playback), Clip
            (for repeated playback)     and TargetDataLine (for
            recording).
            Here, we want to do normal playback, so we ask for
            a SourceDataLine.
            Then, we have to pass an AudioFormat object, so that
            the Line knows which format the data passed to it
            will have.
            Furthermore, we can give Java Sound a hint about how
            big the internal buffer for the line should be. This
            isn't used here, signaling that we
            don't care about the exact size. Java Sound will use
            some default value for the buffer size.
          SourceDataLine     line = null;
          DataLine.Info     info = new DataLine.Info(SourceDataLine.class,
                                                             audioFormat);
          try
               line = (SourceDataLine) AudioSystem.getLine(info);
                 The line is there, but it is not yet ready to
                 receive audio data. We have to open the line.
               line.open(audioFormat);
          catch (LineUnavailableException e)
               e.printStackTrace();
               System.exit(1);
          catch (Exception e)
               e.printStackTrace();
               System.exit(1);
            Still not enough. The line now can receive data,
            but will not pass them on to the audio output device
            (which means to your sound card). This has to be
            activated.
          line.start();
            Ok, finally the line is prepared. Now comes the real
            job: we have to write data to the line. We do this
            in a loop. First, we read data from the
            AudioInputStream to a buffer. Then, we write from
            this buffer to the Line. This is done until the end
            of the file is reached, which is detected by a
            return value of -1 from the read method of the
            AudioInputStream.
          int     nBytesRead = 0;
          byte[]     abData = new byte[EXTERNAL_BUFFER_SIZE];
          while (nBytesRead != -1)
               try
                    nBytesRead = audioInputStream.read(abData, 0, abData.length);
               catch (IOException e)
                    e.printStackTrace();
               if (nBytesRead >= 0)
                    int     nBytesWritten = line.write(abData, 0, nBytesRead);
            Wait until all data are played.
            This is only necessary because of the bug noted below.
            (If we do not wait, we would interrupt the playback by
            prematurely closing the line and exiting the VM.)
            Thanks to Margie Fitch for bringing me on the right
            path to this solution.
          line.drain();
            All data are played. We can close the shop.
          line.close();
            There is a bug in the jdk1.3/1.4.
            It prevents correct termination of the VM.
            So we have to exit ourselves.
          System.exit(0);
     private static void printUsageAndExit()
          out("SimpleAudioPlayer: usage:");
          out("\tjava SimpleAudioPlayer <soundfile>");
          System.exit(1);
     private static void out(String strMessage)
          System.out.println(strMessage);
}

Question about the Ni-DAQ function used in VB

thanks for the previous answer first!
I found that my computer has not installed the Measurement Stduio. When i wanna add module with file nidaq.bas, it shows nothing. Therefore, i download this file and nidaqcns.inc file from the web. Then i add them into VB project.
When i use the function, as i don't how to use them. I just simply copy the "AI_Change_Parameter (deviceNumber, channel, paramID, paramValue)" and see the effect. But it states that "invalid outside procedure". Thereafter, i try just input 1 instead. same statement arouse.
So, my question is how to use them, because i don't have the example.
Thank you very much

It's hard to say for sure without seeing some code, but it sounds like you might be calling the function outside of a subroutine or function. Please verify that the call to AI_Change_Parameter is in a subroutine or function and if you're still getting the error, please post the code that's causing the error. Thanks.

TS3274 Can't open "About" in the General function; after a nano second it defaults back to the home screen;

How do I access the "About" function?
What causes my iPad to default back to the home screen without allowing access to the "About" function?

Here are a couple of things to try.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again.
You can also try quitting the settings app and restart the iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If neither of those things help, you may have to restore the iPad in order to get the settings app to function properly again.

11g client questions about Server Explorer lookup functionality

At my job we are looking to replace another sql developer tool with ODT but there appears to be some bugs in the system still. Maybe I could get some help with these issues. We are currently using VS2005.
First of re-opening a connection after it has timed out is painful. The only way I have found to reconnect (besides restarting VS) is to close the connection, open the connection and then go to modify connection and say OK, but that procedure is not 100%.
Second in package bodies when double clicking on a procedure in the body it may or may not take your cursor to that selected procedure. I have been trying to figure out what the conditions are that will allow this lookup to work correctly I have even re-created existing packages with the ODT package wizard and it will still not focus on the selected procedure.
Another thing I dont really like is that is the package body is broken you don't know it just by looking at the package tree, you have to explode the package spec to see the body with the red x. It would be nice if the body broke it would break the spec for easy scan for broken packages.
One more request for a feature and I'm done. I wish there was a Find that would work with the server Explorer where I could say I want all the EMP table references and it would give me all of the views, procedures, packages where that table is used. This is one of the popular functions with our current sql developer tool and would be nice to it in ODT.
I am really excited about this product and can't wait to see what features are added next.

Thank you very much for the detailed feedback! See below for my comments:

Glad you are looking into ODT. However, keep in mind that it is not a 100% replacement for Oracle SQL Developer which has more features. ODT is geared towards the Visual Studio developer. You should still have a look at Oracle SQL Developer as well, in case it suits you better.
First of re-opening a connection after it has timed out is painful. The only way I have found to reconnect (besides restarting VS) is to close the connection, open the connection and then go to modify connection and say OK, but that procedure is not 100%.
In general with any Oracle application, when a connection times out you generally have to close and then reopen the connection to get going again. So what you are seeing is expected. I guess we could try to automate this for you, set via an options page. But, a better question is - how come the connections are timing out so often? Maybe you should discuss with your DBA if the timeouts are set unreasonably. Or even better, if you manage the database, just turn off the connection time out.
Second in package bodies when double clicking on a procedure in the body it may or may not take your cursor to that selected procedure. I have been trying to figure out what the conditions are that will allow this lookup to work correctly I have even re-created existing packages with the ODT package wizard and it will still not focus on the selected procedure.I have heard this being reported but I haven't been able to reproduce it myself. It always works for me. Can you attach a create script to this thread that could let me reproduce it?

Another thing I dont really like is that is the package body is broken you don't know it just by looking at the package tree, you have to explode the package spec to see the body with the red x. It would be nice if the body broke it would break the spec for easy scan for broken packages.
That's an interesting suggestion - a top level icon to indicate that something in the package is broken, the spec or the body. In Oracle a package is really two pieces, the spec and body and we are trying to portray it as one thing.
One more request for a feature and I'm done. I wish there was a Find that would work with the server Explorer where I could say I want all the EMP table references and it would give me all of the views, procedures, packages where that table is used. This is one of the popular functions with our current sql developer tool and would be nice to it in ODT. This is an excellent suggestion. What tool are you currently using?

I am really excited about this product and can't wait to see what features are added next.One of the biggest new features is Performance Analyzer. The tricky part of Perf Analyzer is to get enough database activity to generate helpful reccommendations. But once you do, I think it is a great feature.

Few questions about Satellite A300D-14P functionality

I have model Satellite A300D-14P for one month. Warranty 2 yrs. I have few questions, and asking for help, and suggestions what I should do?
*My camera quality * is VERY poor, Only with very much light on, I can get generally ok picture quality. Indoor, beside turned on both options, night mode or backlight compensation I hardly can see my face, very dark and poor quality. Second problem is blue led light, it is annoying because half of picture is always blue, somehow that light taking half picture which is always blue:((( I used notebook model from L300 series ( cheaper than mine) with same camera and that blue light, it is working perfectly :(
*Battery life and start up Vista OS*? ??In power save mode hardly 1.5h ??? Just surfing and nothing else....I asked Toshiba support here in Serbia about that and they told me that it is normal, and measuring of battery life (2, ...h) by specifications, is when my display is off and computer don't do anything ??? They also told me that normal start up time for Vista OS is around 1.45min maybe more???
If I install win XP is it possible to get battery life longer?
Do I need to go in Toshiba service or what?
Thank you very much and sorry if I am boring :))))

Hay Nikola
You are not boring at all and welcome on this forum.
I don't know where to start. ;).
I have Satellite A300-1LI in front of me and I use it about a month now. Start-up time is very interesting theme and with right configuration you can optimise it and make it much shorter as with factory setting. Please read one very interesting thread about it under http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=134947
Do the same with your Satellite and I hope you will be satisfied.
Battery running time? I must say that information about two hours is realistic and I can confirm it. The same on my Satellite. But to be honest for mobile computing it is OK. I have changed several notebooks and just business notebook Tecra has had linger battery running time. What you can do is to check Toshiba support site and pick up info about more powerful battery. I am not sure but you can use Battery Pack (Li-Ion, 9 Cell, 6000mAh).
About cam I cannot say much. On my Satellite it works OK and I am satisfied. OK the quality is not the same like on good external webcams but for integrated cam it is OK.
If you are not satisfied try to talk with nearest service or try to compare it with some other Satellite by your local dealer.
So Nikola, if you have more questions please post again.

A quick question about the htmldb_item.checkbox function

I know many posts about checkbox have been posted, yet I couldn't find the answer after some searches.
I have something like:
select
htmldb_item.checkbox(1, col_name)
from...
What I need is to have is the the heading of the checkbox column same as what the wizard does. I mean you can 'check all' with that. If I put a string after the right parentheses, I got that string rendered as the name of the checkbox column, which was not I want.
I couldn't find the answer from the document, neither from the how-to.
Thanks in advance.

I couldn't find the answer from the document, neither
from the how-to.Do you want a checkbox as the header for the checkbox column? So you can check/uncheck all the checkboxes? If so, this is addressed directly in the how-to.
If this is not what you want I don't understand exactly what it is that you're attempting. Perhaps some elucidation would be in order?
