Questions on Column Fromatting example.

Hi Tech Gurus,
I am trying to implement "Column Formatting" example from Oracle XML Publisher - User Guide(PartNo: B13817-03) pdf. It is working fine and could able to get similar kind of output.
When all the columns are displayed, the table in output occupies certain amount of size in the page. When I try to hide one column out of three, the width/size of the table is coming down. Size of the table in second output is not big as in the first output.
My requirement is, table size should not vary accordning to the number of columns. The table size should be the same and two columns should share the total table length equally or as per the giving settings.
How I can achieve this.
Need urgent help on this.
Regards,
Chandra.

I said
if we select columns with same name from different table, alias is useful but no way related to query performance.

Db_stat output question (last column value?)

Hi,
Searched everywhere, can not find this mentioned anywhere. What are the meanings of the columns in the db_stat -C output, for example:
Locks grouped by lockers:
Locker Mode Count Status \--------------- Object \------------
1 dd= 0 locks held 2 write locks 0 pid/thread 20910/1121282384
1 READ 1 HELD 840055011:840055011 handle 2
1 READ 1 HELD 840055011:840055011 handle 0
4 dd= 0 locks held 0 write locks 0 pid/thread 20910/1121282384
5 dd= 0 locks held 2 write locks 0 pid/thread 20910/1121282384
5 READ 1 HELD 840055038:840055038 handle 2
5 READ 1 HELD 840055038:840055038 handle 0
I take this to indicate:
Locker 1 has two READ locks on 840055011, which is an open handle
Locker 4 had been declared, but is now empty, awaiting its call to duty
Locker 5 has two READ locks on 840055038, again, an open handle
The pid and thread information are self-describing I believe.
My questions are, what would the difference be between the two different READ locks in, say, locker 1, one line ends w/ 2, the other w/ 0. Is this a problem in my code, could I possibly have opened the same handle twice?
Additionally, I know the database handle is being named 840055011 but is listed as "840055011:840055011", is this expected, or again, might I have an issue. I'm fairly sure this is simply naming and probably arbitrary.
If there is a source for the db_stat output that I have missed, by all means, please let me know, I've tried my best to RTFM, but couldn't find many M's.
FYI: transactional environment using the Java binding (not JE)
Thank you

Design Question: huge column is slowing app, what's best way to speedup?

Hello All,
I have a DPL application that is getting a bit heavy due to one column and needs to be tweaked and wanted to ask people's advice on the best practice to speeding it up. I have an entity that is tracking versions of statistical data.
@Entity
public class ResourceVersion {
     @PrimaryKey(sequence = "resource_sequence")
     @XmlAttribute
     private Long id; //internal primary key
     private byte[] data; //the field slowing everything down.
     @SecondaryKey(relate=Relationship.MANY_TO_ONE)
     private String resourceId; //externally visible key.
     private String name; //field that's actually needed.
     //2 more fields that aren't relevant to example.
     //some getters and setters.
The byte[] data field can be several megabytes and is making the application slow as my DAO layer is processing a few megabytes of data and then discarding them for the web layer.
To abstract the problem:
* I have a CRUD application with a single entity.
* My page that lists the entities is getting slow.
* I have a bean with 6 fields.
* I need 3 of the fields for the page that's listing the entities. The other 3 are only used by a tiny subset of the application.
I need to stop retrieving the large data field for pages that don't need it. I need a subset of my bean.
The way I see it, I have 2 options:
1. Figure out a way using the DPL to retrieve a subset of the fields. Is it even possible?
2. Break the bean into 2, one containing the fields needed for listing and one bean that just stores the data.
My assumption is that I have to break the byte[] field into it's own entity. I thought I'd just quickly post to make sure there's not an easier option.
Thanks,
Steven

Hi Steven,
You're correct that BDB does not support partial record read/write, and therefore the best solution is to break the large blob out into a separate entity (or even store it in a file).
See:
http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#3
Partial data is not supported at all for the DPL, but as noted in the FAQ the limited support for it in the base API provides very little performance advantage, if any at all.

Column subsetting example

The Oracle documention says that column subsetting is possible with the replication. Does anyone have an example ?
-- Daniel

I'm just curious-- is there a reason that you're
using CREATE_SNAPSHOT_REPOBJECT rather than
CREATE_MVIEW_REPOBJECT? I realize that they do the
same thing, but the fact that you're referring to an
old procedure name makes me concerned that you may be
referring to some older documentation which may be
doing things in an older and more complicated
fashion.
If it's not a multimaster environment, why not just
create the materialized view on the remote system,
toss it in a refresh group if necessary, and call it
a day?
Can you post the exact SQL you used in your steps?
The error generally means that some of the
parameters you specified in one or more of the
earlier steps are in conflict, so we need to see
exactly what you're doing.
JustinJustin, I use CREATE_SNAPSHOT_OBJECT because it's the command generated by the deployment templates. However, rest assured that I use the lastest documentation. Here is a script that reproduces the problem :

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);
}

I didnot go thru the code you posted but I know that the following workstry {
        // From file
        AudioInputStream stream = AudioSystem.getAudioInputStream(new File("audiofile"));
        // From URL
        stream = AudioSystem.getAudioInputStream(new URL("http://hostname/audiofile"));
        // At present, ALAW and ULAW encodings must be converted

Question on Passivation / Activation example in Dev Guide

Adf 11g
Hello
I'm loading some values into the session UserData in my application module PrepareSession.
As I understand things I need to passivate/activate this information.
However the example in the Fusion Dev Guide on page 39-19 for the passivation
seems to be missing the caller to super.passivateState.
Is this correct ?
Best Regards
Paul

Surprisingly, no. The superclass method is basically a no-op. This method isn't involved in passivating the standard transactional and non-transactional state; it's just for custom data. Standard passivation takes place in passivateState(int, byte[], int).

CreateView (join) question, deep XML PO example

I'm trying to create a database view that makes the data from the PO example available via SQL. Recall that the PO example has a deep XML structure (header and POLINES) which is parsed into two objects PO and POLINES. PO is a child of PublicObjects, and I've sucessfully created a view on just it. Now I want to have a view that joins the header to the lines. POLINES object is a child of APPLICATIONOBJECT.
When I try to setup the JoinQualification, I get
Exception :oracle.ifs.common.IfsException: IFS-22701: PURCHASEORDERLINEITEM is not an alias or className
oracle.ifs.common.IfsException: IFS-22701: PURCHASEORDERLINEITEM is not an alias or className
Well gee, I thought it was.
Help?

For anyone else trying to do this... I switched to trying to join to the "Rejection" object. The mistake was that I was trying to join PurchaseOrder to Rejection, without including Rejection in the Search:
scp.addSearchClass("PURCHASEORDERREJECTION");

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

Every thing is going fine, but there is a comment in the java code that I don't understand.

      //access the ADF binding layer and access the tree binding that
      //populates the table
        BindingContext bctx = BindingContext.getCurrent();

        String rwKeyString =

What does this comment mean?

        //change the tree binding iterator dependency to a later point

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?

What does this comment mean?
         //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

JUCtrlHierBinding model =
               (JUCtrlHierBinding) bindings.get("DepartmentsView1");
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.

Essbase RPD question - 2 columns

We build an Essbase BSO cube with historical data. Linked it to OBI (nothing special in the RPD done).
Then we put a filter onto a column: FILTER("FinHist"."FinHist - measure" USING ("Years#1"."Years - Default" = '2006'))
This works.
BUT when we add a second column with e.g. FILTER("FinHist"."FinHist - measure" USING ("Years#1"."Years - Default" = '2005'))
then we get no results at all - even though both FILTERS alone give a result.
(we are on OBIEE 11.1.1.6.7 and Essbase 11.1.2.1)

In Oracle BI you'd typically fix this problem by creating a join between the two datasources using Process Key as the key. Can you do something similar with GRC?

Question about JAI posted example?

Thank you
I just wondered if I could ask, I found this example JAI code on the web. The code compiles, but in the example said they missed out some lines at the begining, do you these missing lines were to read-in a image?

Question in usrp transmitter example

In the usrp transmitter example:
what is the exact packet structure?
what is the padding samples? and how it differs from padding bits? and what is the fuction of the padding bits?
what is the function of the blank frame
thanks in advance

The packet is structured as follows, in bits:
The packets are padded because the transmitter and receiver are not sharing any timing information, which means data could potentially be lost. By adding padding samples, we are able to ensure that when the packet is received, none of the data will be lost at the front and back of the transmitted frame. Take a look at this thread, which discusses this in more depth.
If you take a look at the block diagram of the USRP Packet Transmitter VI, you'll see a case structure that determines when to send packets to the receiver. If the case structure reads the queue of samples to be sent as empty, it will instead send a blank frame matching the size specified in the above snippet. The blank frame is used as an empty packet to ensure the connection is not lost. If we were to simply not send any packet, then the receiver might assume that the connection was lost when instead we are simply not sending anything. By sending an empty packet, the receiver knows the connection is still active, and can wait for a packet of actual data.

Conky config question - running in multiple columns?

Is it possible to display conky's output in rows rather than in columns? Example: I want to more or less cut my config in 1/2 and have the temps+ everything under them appear to the right of the CPU usage bit.

I put the 4 files in my home directory and named them
.conkyrc
.conkyrctop
.conkyrcnet
.conkyrcfile
I use the following bash script to start them all
#!/bin/bash
conky -c ~/.conkyrc &
conky -c ~/.conkyrctop &
conky -c ~/.conkyrcnet &
conky -c ~/.conkyrcfile &
Only the script needs to be executable. Also the files are sized for 1280x1024 so if you use a different resolution you will have to change gap_y values and minimum_size values to accomodate.

XSQL SVG Example questions

The SVG example provided with the XSQL servlet is excellent and illustrates at least 5 different (and very useful) techniques. Congrats to whoever came up with it.
This one example shows SVG, named templates, use of xsl:variable, use of xsl_param, use of xsl:with-param, use of xsl:call-template and the apparent use of java classes from a jar file ala java server pages.
The example also raises several questions:
1. The example uses two namespace declarations I haven't seen before -
xmlns:Color="http://www.oracle.com/XSL/Transform/java/java.awt.Color"
and
xmlns:Integer="http://www.oracle.com/XSL/Transform/java/java.lang.Integer"
These appear to be allowing the use of Java classes in some jar file similar to the way Java server pages might do it.
It this correct? Is this because these two classes were built-in to the XSQL servlet? What other classes can be used? All of them? From any jar file? Is more documentation available?
2. What does the 'doctype=system="svg-19990812.dtd"' line do? There is no such DTD on my system but the demo works fine. There are references to DTDs with similar names in the FOP samples and in Adobe's samples but the name is slightly different.
3. Why is the media-type image/svg? The SVG 1.0 spec dated 2 Nov 2000 in section 1.2 says the SVG mime type is "image/svg+xml".
4. Why is there no namespace declaration for the svg tag or any of the svg related tags? Samples from other vendors seem to always have a declaration.
Thanks again for a great piece of code.

Rick,
You'll find a further-refined, and fully-explained version of the SVG example in Chapter 16 of Building Oracle XML Applications. This chapter covers the use of XSLT extension functions and illustrates how to use Java extension functions with the Oracle XSLT engine.
[list=1]
[*]The two namespaces you list are the way that the Oracle XSLT engine allows you to map extension functions in a namespace to methods of a Java class. This example illustrates using two different built-in classes of the JDK, java.awt.Color and java.lang.Integer. These are not specific to (or built-in in any way to the) XSQL processor or the XSLT engine, but are base classes in the JDK. You can use any Java extension functions in your XSLT stylesheets. The only requirement is that you (1) get the namespace correct to assign a namespace to the appropriate fully-qualified classname, and (2) make sure the classes you want to use are in the CLASSPATH.
[*]The <xsl:output> attribute doctype-system provides a value to be used for the SYSTEM URI of the <!DOCTYPE in the transformed output. The particular value was required by the SVG draft at the time I built the demo. It must be handled by a special entity-resolver built into the SVG Viewer that you're using, which explains why not having on your system as a physical file doesn't stop the demo from working.
[*]The media-type is image/svg instead of image/svg+xml because the SVG demo was built before the final draft of SVG went out. This value was apparently changed in one of the final drafts. It appears that the Adobe SVG viewer registers itself as the handler for both.
[*]See http://www.w3.org/TR/SVG/struct.html#NewDocument. The spec appears to allow both unqualified use of <svg> as well as namespace-qualified <svg:svg> when SVG is embedded within another document.

OO question in LabVIEW example

Hello,
I am trying to learn OO and I have a question in the LabVIEW examples. See the attached image
What is the protected VI's? It looks like a collection of VIs with a type def. Isn't this a class? Why isn't it a class? What is going on?
Thanks

No image attached. Which example are you looking at?
