Resizing redolog

Hi all,
we have redo log group with 50MB of size and we need to resize (add new) redo log file and also we have DR.
Now if I resize the group on Primary suppose 100 MB of each, then what about DR ?
What I need to do with DR to sync these changes made in Primary ?
Is there any kind of parameter ?
Please suggest.
Thanks !

Hi,
Whenever you add an online redo log file to the primary database, you should add corresponding online and standby redo log files to the standby database.
Please see the documentation for details.

Resize online redolog files, make RMAN obsolute backups as usable

Dear Guru's,
I have following doubts, please clarify me on the same. thanks in advance
1. why can not we resize online redolog files instead of re-creating the same with large size and remove the older onces.
2. How can we make RMAN obsolute backups as usable ?
Thanks.

Hi Aman,
Thanks for replay...
Regarding RMAN, plz look into below issue.
I configured RMAN backup recovery window of 15 days. after 15 days the backupsets which were older then 15 days are obsolute. now i have to restore the backup of 15 days older(obsolute backupsets) backupsets to the database. but when i do restore it defaulty takes latest backupsets other then obsolute onces.
how do i restore older(obsolute backupsets) backupsets to the database?
If i used the CHANGE cmd, how to do that.
RMAN> change backupset tag weekly_backup_20052013_02:45 _______________
do i make latest backupsets unavaliable to restore the older once....
RMAN> change backupset tag weekly_backup_20062013_02:00;
Thanks in advance...........
Obsolete backups are always usable, until you delete them with DELETE OBSOLETE.
If you want to restore from a backup other than the latest, use an until clause:
run {set until time = 'sysdate - 15';
restore database;}

Resizing online and standby redo log in dataguard setup.

In 10gr2 dataguard i would like to increase redo logsize from 50M to 100M.
on primary
standby_file_management=manual
added online redo groups with 100M
log switched
drop old one and readded with 100m
deleted log added in step2.
same for standby redo logs.
On standby
was able to resize standby redo logs.
but cannot resize online redologs status is clearing or clearing_current.
please comment. thanks.

I assume you just had to wait until the Primary switched out of that online log so it became inactive at the standby as well? We track where the Primary is by marking the online redo log files at the standby as clearing_current so you can tell where the primary was at any given moment.
Make sure you create new standby redo log files at the Primary and Standby to match the new online redo log file size.

I see that the redolog space request is high. I resized the redolog by 125m but still shows that the space request parameter has not changed. I dropped the redolog files and resized it to 125m. What i should do to reduce the space request close to 0?

Why increase log_buffer?There is a direct correlation between "redo log space requests" and a too-small log_buffer.
The Oracle Documentation notes:
"The redo log space requests Oracle metric indicates the active log file is full and Oracle is waiting for disk space to be allocated for the redo log entries. Space is created by performing a log switch.
Small Log files in relation to the size of the SGA or the commit rate of the work load can cause problems. When the log switch occurs, Oracle must ensure that all committed dirty buffers are written to disk before switching to a new log file. If you have a large SGA full of dirty buffers and small redo log files, a log switch must wait for DBWR to write dirty buffers to disk before continuing.
http://www.dba-oracle.com/t_log_buffer_optimal_size.htm
MetaLink note 216205.1 Database Initialization Parameters for Oracle Applications 11i, recommends a log_buffer size of 10 megabytes for Oracle Applications, a typical online database:
A value of 10MB for the log buffer is a reasonable value for Oracle Applications and it represents a balance between concurrent programs and online users.
The value of log_buffer must be a multiple of redo block size, normally 512 bytes.
Hope this helps. . .

Resizing Log files

Hi All,
Oracle 10.2.0.4 on RHEL5.
We were getting "checkpoint not complete, Thread 1 cannot allocated new log..." in alert log. Also log switches were every 3/4 mins on Night batch updates.
Log file switch completion waits was high with average 30ms.
My redo logs and control files shared the same mount point.
Steps taken;
1> Relocated the redo logs to a different mount point. (So
2> Resized the redologs to 1G. (Current value was 150M).
..The value I derived after setting the fast_start_mttr_target..and checking the optimal_size (it was 900M)
Impact;
In day-time OLTP some transactions taking longer time.
Please advice...

Resized animated gif ImageIcon not working properly with JButton etc.

The problem is that when I resize an ImageIcon representing an animated gif and place it on a Jbutton, JToggelButton or JLabel, in some cases the image does not show or does not animate. More precicely, depending on the specific image file, the image shows always, most of the time or sometimes. Images which are susceptible to not showing often do not animate when showing. Moving over or clicking with the mouse on the AbstractButton instance while the frame is supposed to updated causes the image to disappear (even when viewing the non-animating image that sometimes appears). No errors are thrown.
Here some example code: (compiled with Java 6.0 compliance)
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test
 public static void main(String[] args)
 new Test();
 static final int IMAGES = 3;
 JButton[] buttons = new JButton[IMAGES];
 JButton toggleButton = new JButton("Toggle scaling");
 boolean doScale = true;
 public Test()
 JFrame f = new JFrame();
 f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 JPanel p = new JPanel(new GridLayout(1, IMAGES));
 for (int i = 0; i < IMAGES; i++)
 p.add(this.buttons[i] = new JButton());
 f.add(p, BorderLayout.CENTER);
 f.add(this.toggleButton, BorderLayout.SOUTH);
 this.toggleButton.addActionListener(new ActionListener() {
 @Override
 public void actionPerformed(ActionEvent e)
 Test.this.refresh();
 f.setSize(600, 300);
 f.setVisible(true);
 this.refresh();
 public void refresh()
 this.doScale = !this.doScale;
 for (int i = 0; i < IMAGES; i++)
 ImageIcon image = new ImageIcon(i + ".gif");
 if (this.doScale)
 image = new ImageIcon(image.getImage().getScaledInstance(180, 180, Image.SCALE_AREA_AVERAGING));
 image.setImageObserver(this.buttons);
 this.buttons[i].setIcon(image);
 this.buttons[i].setSelectedIcon(image);
 this.buttons[i].setDisabledIcon(image);
 this.buttons[i].setDisabledSelectedIcon(image);
 this.buttons[i].setRolloverIcon(image);
 this.buttons[i].setRolloverSelectedIcon(image);
 this.buttons[i].setPressedIcon(image);
Download the gif images here:
http://djmadz.com/zombie/0.gif
http://djmadz.com/zombie/1.gif
http://djmadz.com/zombie/2.gif
When you press the "Toggle scaling"button it switches between unresized (properly working) and resized instances of three of my gif images. Notice that the left image almost never appears, the middle image always, and the right image most of the time. The right image seems to (almost) never animate. When you click on the left image (when visble) it disappears only when the backend is updating the animation (between those two frames with a long delay)
Why are the original ImageIcon and the resized ImageIcon behaving differently? Are they differently organized internally?
Is there any chance my way of resizing might be wrong?

It does work, however I refuse to use SCALE_REPLICATE for my application because resizing images is butt ugly, whether scaling up or down. Could there be a clue in the rescaling implementations, which I can override?
Maybe is there a way that I can check if an image is a multi-frame animation and set the scaling algorithm accordingly?

How can I get just the text to resize, rather than the entire web page?

I used to be able to re-size just text on a webpage by typing Ctrl + +. Today, the entire webpage re-sizes, and when I move to another page it reverts. (I see this mostly in Facebook.). Why did this change, and can I go back to having just the text re-size?

How can I implement a status bar at the bottom of a resizable application?

Hello all,
I am a JavaFx newbie and I am implementing an application (a Sokoban game), with a menu at the top of the frame and a gaming area covering the rest of the frame. To support the game, I have to load images at certain positions in the gaming area.
The game also includes a level editor with another menubar and where images are set to other positions.
I implemented this in another view, swiching from the game mode to the level editor mode and vice versa is just done by setting the other view visible. Up to now this works, here the important statements building these details:
Group root = new Group();
gameView = new Group(); // for gaming mode
le_view = new Group() // for level editor mode
MenuBar gameMenubar = new MenuBar();
Menu menuGame = new Menu(bundle.getString("MenuGame"));
... building the menu items and menues ...
gameView.getChildren().add(gameMenubar);
ImageView buildingView[][] = new ImageView[22][22];
for (nCol = 0; nCol < 22; nCol++) {
 for (nRow = 0; nRow < 22; nRow++) {
 buildingView[nCol][nRow] = new ImageView();
 buildingView[nCol][nRow].setX(nCol * 26 + 5);
 buildingView[nCol][nRow].setY(nRow * 26 + 40);
 gameView.getChildren().add(buildingView[nCol][nRow]);
gameView.setVisible(true);
root.getChildren().add(gameView);
... same stuff to build the le_view ...
le_View.setVisible(false);
root.getChildren().add(le_View);
Scene scene = new Scene(root, 800, 600, Color.CORNSILK); Now I want to introduce a status bar at the bottom of the frame, which of course has to follow the bottom of the frame, if it is resized. And of course the menu and the status bar should not grow vertically, if the height of the frame is increased.
The implementation seems to be easy with StackPane for the frame and one BorderPane for each mode.
For the first step I only tried implementing the game mode with only one BorderPane (just setting the menu, the gaming area and the status bar each into a HBox and setting these three HBoxes at the top, into the center and at the bottom). I also tried this via GridPane and via VBox; I always get any erroneous behaviour:
Either the menubar is visible, but the menus do not pop up the menu items, or the anchor point of the menu and of gaming area are set 100 pixels left of the left frame border and move into the frame when the frame width is increased, or the menu is set 20 pixels below the top of the frame, or HBox with the menu grows when the frame height is increased, so that the anchor point of the gaming area moves down.
Can you describe me a correct construction of such a frame? Thanks in advance.
Best regards
Gerhard

Hello Gerhard,
Glad the code helped, thanks for a fun layout exercise.
For the draft code I just pulled an icon off the internet over a http connection.
If you haven't done so already place any icons and graphics you need local to your project, so that resource lookups like:
Image img = new Image("http://www.julepstudios.com/images/close-icon.png");become
Image img = new Image("close-icon.png");then performance may improve.
Another possible reason for your performance problem could be that when you use a vbox, the vbox content can overflow the area of the borderpane center and might be sitting on top of the menu pane, making you unable to click the menu (which is what happens to me when I try that with the draft program with the vbox wrapping mod, then resize the scene to make it smaller). This was a trick which caught me and the reason that I used a Group originally rather than a vbox. I found a vbox still works but you need to tweak things a bit. The trick I saw was that the order in which you add stuff to the borderpane is important. The borderpane acts like a stack where the last thing added floats over the top of everything else if you size the scene small enough. For your project you want the menu on top always, so it always needs to be the last thing added to the borderpane, but when you swap in the level pane for the game pane, then back out again, the game pane can end up on top of the menu which makes the menu seem like you can't click it (only when the scene is sized small enough). It was quite a subtle bug which took me a little while to work out what was happening. For me the solution was to add just one vbox to the center of the border, and then swap the game pane and the level editor in and out of the vbox, that way the center of the layout always stayed behind the menu bar and the status bar.
I added some revisions to reflect the comments above and placed some comments in the code to note what was changed and why.
public class SampleGameLayoutRevised extends Application {
public static void main(String[] args) { Application.launch(args); }
public void start(Stage stage) throws Exception {
 final BorderPane gameLayout = new BorderPane();
 final Group gameView = new Group();
 final MenuBar gameMenubar = new MenuBar();
 final Menu gameMenu = new Menu("Mode");
 final VBox centerView = new VBox();
 centerView.setStyle("-fx-background-color: darkgreen"); // we set a background color on the center view to check if it overwrites the game menu.
 MenuItem playGameMenu = new MenuItem("Play Game");
 MenuItem levelEditMenu = new MenuItem("Edit Levels");
 gameMenu.getItems().add(playGameMenu);
 gameMenu.getItems().add(levelEditMenu);
 gameMenubar.getMenus().add(gameMenu);
 final StackPane levelEditView = new StackPane();
 levelEditView.getChildren().add(new Text("Level Editor"));
 ImageView buildingView[][] = new ImageView[22][22];
 Image img = new Image("http://www.julepstudios.com/images/close-icon.png"); // use of http here is just for example, instead use an image resource from your project files.
 for (int nCol = 0; nCol < 22; nCol++) {
 for (int nRow = 0; nRow < 22; nRow++) {
 ImageView imgView = new ImageView(img);
 imgView.setScaleX(0.5);
 imgView.setScaleY(0.5);
 buildingView[nCol][nRow] = imgView;
 buildingView[nCol][nRow].setX(nCol * 20 + 5);
 buildingView[nCol][nRow].setY(nRow * 20 + 40);
 gameView.getChildren().add(buildingView[nCol][nRow]);
 final VBox statusBar = new VBox();
 final Text statusText = new Text("Playing Game");
 statusBar.getChildren().add(statusText);
 statusBar.setStyle("-fx-background-color: cornsilk"); // we set a background color on the status bar,
 // because we can't rely on the scene background color
 // because, if the scene is sized small, the status bar will start to overlay the game view
 // and if we don't explicitly set the statusBar background the center view will start
 // to bleed through the transparent background of the statusBar.
 gameLayout.setCenter(centerView); // we add the centerview first and we never change it, instead we put it's changeable contents in a vbox and change out the vbox content.
 gameLayout.setBottom(statusBar);
 gameLayout.setTop(gameMenubar); // note the game layout is the last thing added to the borderpane so it will always stay on top if the border pane is resized.
 playGameMenu.setOnAction(new EventHandler<ActionEvent>() {
 public void handle(ActionEvent event) {
 centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
 centerView.getChildren().add(gameView);
 statusText.setText("Playing Game");
 levelEditMenu.setOnAction(new EventHandler<ActionEvent>() {
 public void handle(ActionEvent event) {
 centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
 centerView.getChildren().add(levelEditView);
 statusText.setText("Editing Level");
 playGameMenu.fire();
 Scene scene = new Scene(gameLayout, 800, 600, Color.CORNSILK);
 stage.setScene(scene);
 stage.show();
}Other than that I am not sure of a reason for the slowdown you are seeing. In my experience JavaFX has been quick and responsive for the tasks I have been using it for. Admittedly, I just use if for a bunch of small trial projects, but I've never seen it unresponsive for a minute.

In Windows 8.1, the Thunderbird window keeps resizing

I have a new Transformer T100A laptop, running Windows 8.1 Pro. I run Thunderbird in desktop mode. The height of the Thunderbird window keeps getting small, while the width remains the same. I usually have my folder mails in the top pane, and the open message in the bottom pane. When I open Thunderbird, it often, but not always, comes up with such a short window that I can't see any of the open message at all, and only a few lines of the messages in the folder. This happens often even when I haven't closed Thunderbird, but the computer has gone into battery saving mode. This is not a huge problem, but it's annoying to have to resize the window almost every time I use Thunderbird.

How resize pictures in table on PAGES 5.2?

The new version 5.2 was be optmized for import image in table, but how resize these pictures in table?

DO NOT use Pages 5.2. Use Keynote or Numbers. The latest versions of these apps are stable. Pages 5.2 nothing but trouble.
Here is what I do with my art, which must be perfect for commercial printing and other purposes.
Export the page with your table and art out as a PDF. Then bring the PDF into Adobe Illustator and make any changes you need to get the art looing exactly like what you want. Save the art from AI ouit to PDF. AI creates bullet proof PDF files. Then drag the clean PDF back into Pages.
One reason AI is the preferred route is that Adobe comlpliant PDF files are the standard in the commercial printing industry. These days, all files going to commercial printers must be in clean PDF format. As you would expect, there are some excellent apps for pre-flighint PDF files.
The final reason for using PDF for art is that your illustrations will move cleanly into iBook Author for iBooks and apps for creating international standard ePubs and Amazon MOBI files.

SAP GoLive : File System Response Times and Online Redologs design

Hello,
A SAP Going Live Verification session has just been performed on our SAP Production environnement.
SAP ECC6
Oracle 10.2.0.2
Solaris 10
As usual, we received database configuration instructions, but I'm a little bit skeptical about two of them :
1/
We have been told that our file system read response times "do not meet the standard requirements"
The following datafile has ben considered having a too high average read time per block.
File name -Blocks read - Avg. read time (ms) -Total read time per datafile (ms)
/oracle/PMA/sapdata5/sr3700_10/sr3700.data10 67534 23 1553282
I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
2/
We have been asked to increase the size of the online redo logs which are already quite large (54Mb).
Actually we have BW loading that generates "Chekpoint not comlete" message every night.
I've read in sap note 79341 that :
"The disadvantage of big redo log files is the lower checkpoint frequency and the longer time Oracle needs for an instance recovery."
Frankly, I have problems undertanding this sentence.
Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right ?
But how is it that frequent chekpoints should decrease the time necessary for recovery ?
Thank you.
Any useful help would be appreciated.

Hello
>> I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
The recommended ("standard") values are published at the end of sapnote #322896.
23 ms seems really a little bit high to me - for example we have round about 4 to 6 ms on our productive system (with SAN storage).
>> Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right?
Correct.
>> But how is it that frequent chekpoints should decrease the time necessary for recovery ?
A checkpoint is occured on every logswitch (of the online redologfiles). On a checkpoint event the following 3 things are happening in an oracle database:
Every dirty block in the buffer cache is written down to the datafiles
The latest SCN is written (updated) into the datafile header
The latest SCN is also written to the controlfiles
If your redologfiles are larger ... checkpoints are not happening so often and in this case the dirty buffers are not written down to the datafiles (in the case of no free space in the buffer cache is needed). So if your instance crashes you need to apply more redologs to the datafiles to be in a consistent state (roll forward). If you have smaller redologfiles more log switches are occured and so the SCNs in the data file headers (and the corresponding data) are closer to the newest SCN -> ergo the recovery is faster.
But this concept does not really fit the reality because of oracle implements some algorithm to reduce the workload for the DBWR in the case of a checkpoint.
There are also several parameters (depends on the oracle version) which control that a required recovery time is kept. (for example FAST_START_MTTR_TARGET)

Which approach to use for resizing image

There are two ways of resizing images as I know:
1. image.getScaledInstance(width,height,hint);
Using hint like Image.SCALE_AREA_AVERAGING gives somehwat satisfactory resizing.
2. static BufferedImage resize(GraphicsConfiguration gc, BufferedImage source, int w, int h, Object hintValue) {
BufferedImage result = gc.createCompatibleImage(w, h, source.getTransparency());
Graphics2D g2 = result.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, hintValue);
double sx = (double) w / source.getWidth(), sy = (double) h / source.getHeight();
g2.drawRenderedImage(source, AffineTransform.getScaleInstance(sx, sy));
g2.dispose();
return result;
where the hint passed is RenderingHints.VALUE_INTERPOLATION_BILINEAR ;
Now which of the two method method should I use-using image.getScaledInstance() or using AffineTranform ? opr is there any other way which is faster but provides good result?
i am creating an image editor, so the GUI dialog will have oprtion to choose the algorithm. I want the method which provides better result yet faster.

Menu/Toolbar Display Corruption Upon Resizing Window

We're experiencing an issue with one of our workstations where when the Adobe Reader X (10.1.3) window is resized, the Menu/Toolbar displays become corrupt and garbled on the screen (see the attached picture). The Toolbar appears on the top, the frame around the application disappears, and the menubar has to be hovered across for items to appear.
I have uninstalled and reinstalled Adobe Reader, updated the video card drivers, and ensured all Adobe/Microsoft updates have been applied to this workstation.

Was curious to how you were able to change the display resolution - I am unable to even see anything on my desktop... I have connected my power book to another monitor but have the same result.

I resize my window image so everything is correct portion but as soon as I change window to next page the image goes back to small size. How can I stop this occuring. This happens when go on facebook or any other area. Help me please.

size of the general image that I see reduces toby about a third - I resize it by pressing Ctrl key and using my mouse scroll button to expand the whole image so that it fill the screen. As soon as I go to the next page the whole image reverts back to original size and I have to repeat the action again.
