• All parameter memory index for Oracle text indexes

  Hi Experts,

  I'm on Oracle 11.2.0.3 on Linux and have implemented Oracle Text. I'm not an expert in this area and need help on a question. I created the Oracle text index with the default setting. However, in a white paper of oracle, I read that the default setting is perhaps not good. Excerpt from the white paper by Roger Ford:

  URL:http://www.oracle.com/technetwork/database/enterprise-edition/index-maintenance-089308.html

  "(Part of this white paper below. )" ...)

  Index memory as mentioned above, $I entries cached emptied out on the disk each time the indexing memory is exhausted. The default index to installing memory is a simple 12MB, which is very low. At the time of creating indexes, users can specify up to 50 MB, but it is still quite low.                                   

  This would be by a CREATE INDEX, something like statement:

   CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M');  

  Allow index of the parameters of memory beyond 50 MB, the CTXSYS user must first of all increase the value of the MAX_INDEX_MEMORY parameter, like this:

   begin ctx_adm.set_parameter('max_index_memory', '500M'); end;  

  The parameter memory must never be high point causes paging, because this will have a serious effect on indexing speed. The smallest of dedicated systems, it is sometimes advantageous to temporarily reduce the amount of memory consumed by the Oracle SGA (for example by reducing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process. Once the index has been created, the size of the SGA can be increased again to improve query performance. & quot;

  (End of the excerpt from the white paper)

  
  My question is:

  (1) to apply this procedure (ctx_adm.set_parameter) obliged me to log on as user CTXSYS. Is this fair? or can it be avoided and will be based on the application schema? The CTXSYS user is locked by default and I had to unlock it. Is this OK to do it in production?

  (2) what value I should use for the max_index_memory there are 500 MB - my SGA is 2 GB in Dev / QA and / 3 GB in the production. Also in the creation of the index which is the value should I set for the parameter memory index - I had left to default, but how do I change now? Should it be 50 MB as shown in the example above?

  (3) the white paper also refer to the reconstruction of an index to an interval like once a month: ALTER INDEX DR$ index_name$ X REBUILD online;

  -Is this good advice? I would like to ask the experts once before doing this.  We are on Oracle 11 g and the white paper was drafted in 2003.

  Basically, while I read the book, I'm still not clear on many aspects and need help to understand this.

  Thank you

  Index entries are built in memory, and then flushed to disk, memory is exhausted. With a setting of high index memory will mean the index entries can be longer and less fragmented, which provides better performance of the query.  Conversely, a small memory parameter index will mean emptied the disk pieces are smaller, so queries (especially on common words) will have to do a lot more e/s to extract several pieces of index for the words.

• Lexical in several lines and all parameter headers print in PLSQL

  HI team,
  
  I have some requirement in plsql can someone please help with solutions.
  
  1. print the headers on several lines in pl/sql block using the dbms_output
  I have some column FILE_name, creation_date and so on, I want to print multiple line headers
  
  ex:_
  
  Creating files
  Name Date
  -------------------------------------------------------
  xxd_top.txt June 10, 2009
  der_top.txt August 21, 2009
  
  2 using the lexical in plsql block in the cursor as parameter
  
  ex:*
  
  cursor c1 (p_parameter)
  is
  Select * from EMP
  where & p_parameter
  
  and I'm assigning the value of p_parameter in the begin block.
  When compiling I was getting error when compiling.
  
  Please give me some suggestions to solve these problems
  
  Thanks in advance
  Sriram

  If you want to only several lines of DBMS_OUTPUT then call DBMS_OUTPUT. Put_line several times. I'm guessing that you want this layout:

  File        Creation
  Name        Date
  ----------- ------------
  xxd_top.txt 10-Jun-2009
  der_top.txt 21-Aug-2009
  

  The simplest approach would be just something like

  DBMS_OUTPUT.PUT_LINE('File        Creation');
  DBMS_OUTPUT.PUT_LINE('Name        Date');
  DBMS_OUTPUT.PUT_LINE('----------- ------------');
  

  I tried with CHF solution and it worked.

  Post an example of what you have tried that does not work, maybe someone will see what is wrong with it.

• V$ IsSys_Modifiable parameter field values

  Hi all
  
  As you know parameter field IsSys_Modifiable $ v has three values, payment DEFERRED, IMMEDIATE, and FALSE.
  
  in the oracle documentation: http://download.oracle.com/docs/cd/E11882_01/server.112/e17110/dynviews_2087.htm#REFRN30176
  who says
  
  DEFERRED payment means, you can change this setting, regardless of the type of parameter file used to start the instance. PFILE or SPFILE.
  FALSE means, you can NOT change this setting unless a server settings file was used to start the instance. It must be SPFILE.
  
  but, for example, the RECYCLEBIN parameter listed as DEFERRED, which means I can change this setting with "Alter system" and change is performed on subsequenct sessions. This isn't. I can't just change the command 'Alter System', I have to use scope = spfile statement too and if I started my instance of pfile so I can't change it with Alter system again.
  
  so I see no difference between DEFERRED and FAKE? parameters which has so much value has the same effect.

  but, for example, the RECYCLEBIN parameter listed as DEFERRED, which means I can change this setting with "Alter system" and change is performed on subsequenct sessions. This isn't. I can't change just the command 'Alter System', I have to use scope = spfile statement too

  Deferred ways on subsequent sessions, this means that you will need to login once more to see indeed:

• undefined reference to ApplicationUI::slotReadyRead()

  Hello

  I think it's quite a newbie question, but I can't find a solution that is exactly my problem. Basically, I just try to download a PDF file from my application to open it with Adobe Reader software.

  First of all, I tried to download the file with QNetworkAccessManager. I found an example to "'http://developer.blackberry.com/native/reference/cascades/qnetworkaccessmanager.html ' and tried to get him to work, but I always have problems."

  In fact, I get this error message when you compile the application:

  moc_applicationui.cpp:60: refers to 'ApplicationUI::slotReadyRead()' the undefined

  This is my code
  .cpp

  void ApplicationUI::StoreAndInvokePDF(QString url) {
      QNetworkAccessManager *manager = new QNetworkAccessManager(this);
  
      QNetworkRequest request;
       request.setUrl(QUrl("http://qt.nokia.com"));
       request.setRawHeader("User-Agent", "MyOwnBrowser 1.0");
  
       QNetworkReply *reply = manager->get(request);
       connect(reply, SIGNAL(readyRead()), this, SLOT(slotReadyRead()));
  }
  

  and all here

  public slots:
      void slotReadyRead();
  

  When I omit the part in the all, I can compile the application, but the event does not (of course), with this part, I can not even compile.

  In addition, in line with the connect (...) in the .cpp, I do have with this message:

  ApplicationUI::slotReadyRead() has not been labeled as a member of Qt; Make sure that all parameter types are fully qualified.

  I'm quite confused. :/

  Best

  Thomas

  I think I solved it. I just had to set the callback function "void ApplicationUI::slotReadyRead() {}" for the location. Seems logical, but for a beginner this unfinished examples are quite confusing.

• Not labeled as signals Qt signals

  I'm trying to connect the signal wallpaperLockStateChanged HomeScreen, but NDK claims that it is not marked as Qt signals and when I ran the app anyway, NDK does not claim these exist no signal.

  The error is:

  HomeScreen::wallpaperLockStateChanged (bb: platform::WallpaperLockState:Type wallpaperLockState) has not been marked as a Qt signal; Make sure that all parameter types are fully qualified

  This signal is described here in the official documentation

  I tried to copy - paste the name of signal directly from my browser, no luck.

  The code in question looks like this:

  QObject::connect

  (& homeScreen, SIGNAL (wallpaperLockStateChanged (bb: platform::WallpaperLockState:Type wallpaperLockState)),)

  (& applicationUI, SLOT (onWallpaperLockStateChanged (bb: platform::WallpaperLockState:Type wallpaperLockState)));

  The location is defined in applicationui.hpp as a public slot implementation in the .cpp, currently there are that of qDebug("AAA");

  As a side note, I can connect with the signal of lockStateChanged very well.

  So, what happens here? Googling for this does not answer. The only case where this kind of error occurred was settled by do not use the problematic signal altogether

  Here, I am puzzled

  Yes, I'm stupid.

  The reason why it says 'no signal was' is because I put the arguments along, then, instead:

  QObject::connect

  (& homeScreen, SIGNAL (wallpaperLockStateChanged (bb: platform::WallpaperLockState:Type wallpaperLockState)),)

  (& applicationUI, SLOT (onWallpaperLockStateChanged (bb: platform::WallpaperLockState:Type wallpaperLockState)));

  I should put this:

  QObject::connect

  (& homeScreen, SIGNAL (wallpaperLockStateChanged (bb: platform::WallpaperLockState:Type)),)

  (& applicationUI, SLOT (onWallpaperLockStateChanged (bb: platform::WallpaperLockState:Type)));

  In the second example, note the lack of argument of the function.

  I hope this can help some other poor decoration there. Also, the NDK should said QObject to connect has no need of the arguments of the function, that would make a lot of sense more

• How to connect NotificationDialog finished() signal to a process without a head?

  I tried to get a process in the background to handle the signal in my application without head (because NotificationDialogs are now supported for background process).

  However, whenever I try to connect the signal to a slot, I get the following error:

  QObject::connect: Cannot connect (null): Finish (bb:latform::NotificationResult:Type) at MessageProcessor::dialogFinished (bb:latform::NotificationResult:Type)

  
  
  cpp file:
  
  QObject::connect(pNotificationDialog,SIGNAL(finished(bb::platform::NotificationResult::Type)), this,SLOT(dialogFinished(bb::platform::NotificationResult::Type))); //(for this line I also get the warning below)
  //MessageProcessor::dialogFinished(bb::platform::NotificationResult::Type) has not been //tagged as a Qt member; make sure all parameter types are fully qualified
  
  hpp file:
  
  #include 
  
  class MessageProcessor  : public QObject{
  Q_OBJECT
  
  public slots:
  void dialogFinished(bb::platform::NotificationResult::Type value);
  
  };
  
  Is finished() supported for headless apps?
  

  You are probably not initializing pNotificationDialog

  pNotificationDialog = new bb::platform::NotificationDialog(this);

• Watch out, I can't understand

  Hey guys,.

  I wonder if someone can help me with the following warning, I get:

  The path location type Resource Description
  NavigationPane:op() has not been labeled as a Qt slot; Make sure that all parameter types are complete OCTranspoGPS.cpp/OCTranspoGPS/src line 1175 C/C++ Qt problem

  How does a NavigationPane tag:op() as a slot QT to get rid of this warning?

  Here's the line of code which translates the specific caveat:

  Boolean result = connect (results_backAction, SIGNAL (triggered (()), navPane, SLOT (pop (()));

  I get the same warning with each use of pop() as a crack like that.

  Probably missing me something obvious, but I Googled it and can't find anythying.

  Thank you

  Matt M

  It work?
  According to the docs pop() is Q_INVOKABLE. not all things what are slot machines, but the methods are AFAIK, so it should work.

  You cannot add the tag in the code yourself the warning will remain.
  of course, you can write your own Q_SLOT which is properly labeled and call pop() as a regular method, which would eliminate the warning.

• MediaPlayer error() not marked as Qt signal?

  Hello

  Using the SDK 10.1.0.4828 and try to catch the mistakes of MediaPlayer.  Momentics, the line below is reported as a bug and my slot is never called.

       this->connect(&m_player, SIGNAL(error(bb::multimedia::MediaError::Type mediaError, unsigned int position)), this, SLOT(onPlaybackError()));
  

  the error is:

  MediaPlayer::error(bb::multimedia::MediaError::Type mediaError, unsigned int position) has not been tagged as a Qt signal; make sure all parameter types are fully qualified.
  

  the application compiles and works very well, but if there is a mistake in the reading of the media, my onPlaybackError() function never fires.

  How do I make this signal/slot connection to make it work?

  THX,

  J

  Do not include the parameter names in the connect(), only to types. Also, your site must have parameters to your signal, even if you don't use them. If it is not the connection will fail.

  Finally, it is common to save the return value of connect() function and then test it with Q_ASSERT(), so you are alerted to signal/slot connection issues when you run the application. This can save debugging headaches later.

• Selection of understanding... from the query timestamp

  Hello

  I'm stuck with this scenario where we offer production data the developer to achieve a purpose test by altering the critical columns of the company by an arbitrary value continues the update statement.

  Now the problem is when we fire select... from the timestamp request, we are able to display the old corrupted data. I created an example test case scenario:

  CREATE TABLE test1 (identification number);

  added values:

  SQL > select * from test1;

  ID

  ----------

  1

  2

  3

  4

  5

  5

  5

  5

  5

  5

  10 selected lines.

  SQL > update test1 ID = 3 where id = 5;

  6 lines to date.

  SQL > commit;

  Validation complete.

  Now the data in the table are:

  SQL > select * from test1;

  ID

  ----------

  1

  2

  3

  4

  3

  3

  3

  3

  3

  3

  10 selected lines.

  Now when I fire from the timestamp query I am able to see old data:

  SQL > select * from test1 from sysdate timestamp - 5/1440;

  ID

  ----------

  1

  2

  3

  4

  5

  FLASHBACK_ON

  ------------------

  NO.

  SQL > show parameter recyclebin;

  VALUE OF TYPE NAME

  ------------------------------------ ----------- ------------------------------

  Recyclebin OFF string

  Now, I would like to know where oracle recover old data. According to my knowledge, it's going to be fetch these data to undo tablespace If yes then I would like to know is possible to stop this because this could expose the old data of the contracting authority.

  Note:-this isn't a good way to hide the data, but it is a call from management for not no opt data tool because of the license of masking

  You could do a DOF that is not actually change anything:

  orclz > dept desc;

• Issue of Muse of slide show... Lose the will to live.

  Hi all

  I created a small slideshow with the photos.  Using the slide show basis - as well as others in my troubleshooting - each has the same result.

  This slide show [display target frame] is smaller than the majority of the images that I put in it [if to talk - in fact adding via miniature ' add images']

  I add images via bit attached to the miniature section folder icon.

  Setting are set to "Fill Frame proportionally".

  Muse is ignorant of the adjustment controls...   Fill frame proportionally DOES NOT WORK - despite my images as large as the target framework.

  I'm so manually adjust the size of images in destination and positioning when it is required.

  Muse is periodically given size of images.  Usually when I add new images, it goes back and changes the dimensions of the existing image.  Which means that I have to check every image, time and time again.  With usually 5 or 6 on 30.

  I have then quickly save and download.

  The image file must fill the frame - allowing repositioning.

  Checked and checked 'Edit together' - no change.
  

  What is going on?  It is a problem for me as most of my site is based on image.

  I found this app totally useless right now.   My workflow is now a constant circle.

  Mocq.

  An image fades.

  Parameters 'New heroes' and 'New vignette' in the user Options of Widget interface affect the behavior of pictures newly added for most type slide show. For full-screen slideshows or slide shows with heroes for the 100% browser width this setting always change both images in the slideshow and the Assembly of the newly imported images.

  For slideshows that are not full-screen or width 100%, the combination of the "Edit all" parameter in the Widget Options in the user interface and the object > fitting (from the main menu or the menu right click +) can be used to change the editing of an individual hero image or a thumbnail, or change the mounting of all the images of heroes or all the thumbnail images in a slide show.
