• How to view the external cursor opened in a session

  Hi all
  Is there a way to display a cursor open external in a session? Suppose if I want to check if there is a public and open cursor that has been defined in a package, how can I do? I try to play with v$ open_cursor, but I can't make sense.
  
  Best regards

  I want to test a lifetime of a cursor in a session. I don't want to interrogate another session but the same session where the open cursor.

  This probably more experimentation rather than useful in the real world. Suppose I have a package that sets a public cursor (as defined in the package spec) but for reasons of bad programming practice, the cursor is not closed and remains in session until the end view of v$ open_cursor can you tell me if an open cursor exists in the session?

  How do you know if this open cursor has been consumed (not more data), or not? It might be half an hour old, but still perfectly valid (if using the snapshot has not expired).

  I wouldn't say a cursor that was opened for x times a problem. The problem is to have multiple copies of the same open cursor - like which indicates a cursor leak.

  Anyway, you can watch the view V$ OPEN_CURSORS performance virtual - but in my test below, that time is is filled not doing a calculation of time would not work. You can continue this and dig deeper into the data dictionary (and the behavior of the Oracle) to determine if your needs can be met.

• PShop cloning tool - Trailing cursor missing?

  ..., I swore that when I used the Photoshop Clone Stamp tool, I used to have a second cursor "leak".

  I mean, it is, once I have picked my point source (opt/click) and began to slip in the new area I usual brush circle showing the new pixels as I clone, and, as I paint, I would have a second 'source' slider after slider cloning in perfect alignment.  Looking at the source/crawling slider, I would like to know when to stop dragging the clone brush to avoid a new part of the image that I did not want cloning.

  The second/crawling slider disappeared; He was missing for a while now. I have futzed with settings in the palette Source of duplication and reset the tool without result. With the help of Photoshop CS5 12.0.4 on iMac Mac 10.6.8 with standard bluetooth mouse.  Thank you...

  Thus, you do not see the source of the cross cursor?

  Sometimes, especially if the source is a solid color and average value, it can be almost impossible to see.

  Try resetting the PS preferences by pressing the shift + Opt + command you launch Photoshop. You will get a small dialog ok reset preferences to confirm that you did it right.

• Artifacts in El Capitan, using the Zoom feature

  Hi my friends.

  In my iMac 27 "end 2013 with dedicate GeForce GTX 780 M 4 GB GDDR5 has a problem with artifacts on the screen.

  When to use zoom by accessibility options feature, see sometimes vertical lines... In the Yosemite, for example, I had no such problem...

  If move mouse in artifact, it disappear... even erase tool

  

  I have noted in the feedback tools but nothing...

  All solutions?

  I'm having the same issue or similar, but I also use a slider more to zoom. I have a box to open with Apple about this and my Advisor is waiting for news from the engineers. I posted this problem here:cursor leak before I realized that it was related to accessibility features.

  My cursor did this:

  

  

  MacBook Pro (retina, 15 inch, mid-2015)

  Memory: 16 GB

  Processor: 2.5 GHz Intel Core i7

• leak of open cursors

  Hello.
  
  
  I work with a (version 9.2.0.7) database which is accessed by a web applicattion which is at the origin of the leaks of sliders, I looked like a large part of the demand as I can and all statemtens and jdbc result sets appear to be properly closed.
  
  I see that for a single session, increasing the number of open cursors, the application has restarted 3 days ago, but there is a session that has 100 open cursors rigth now, that means in a fortnight that he could reach the maximum number of open cursors.
  
  I have no idea on how to find the sql code that could be responsible for this behavior.
  
  
  I don't think that the following code is responsible for this beahviour, but maybe I'm wrong:
  There is a stored procedure:

  CREATE OR REPLACE FUNCTION REFLEX.DevuelveCursor(query in varchar2)
      RETURN SYS_REFCURSOR
  AS
      c SYS_REFCURSOR;
  BEGIN
      OPEN c FOR query;
  
      RETURN c;
  END;
  /

  This procediure is called from jdbc in this way:

       /*************************** 
       Many lines of code follow here
       ***************************/      
        String queryCursor = "begin ? := DevuelveCursor(?); end;";
        cstmt = conexion.prepareCall(queryCursor);
        cstmt.registerOutParameter(1, OracleTypes.CURSOR);
        cstmt.setString(2, SentenciaContadores);
        cstmt.execute();
  
        rs = (ResultSet)cstmt.getObject(1);
       /*************************** 
       Many lines of code follow here
       ***************************/
        rs.close();
       /*************************** 
       Many lines of code foloow here
       ***************************/
       cstmt.close();
       /*************************** 
       Many lines of code follow here
       ***************************/

  I wonder if only SYS_REFCURSOR is properly closed.
  
  
  
  Thanks in advance.

  Centinul,

  I read it on Metalink. Do not add article, however.

  The closest I can get to now of Note 62143.1, which States as soon as the maximum session_cached_cursors is reached, the 'old' cursors are automatically closed.

  Dbms_sql sliders are a different beast, you must close the explicitlty when you hit an exception.

• Leak memory like PC problem

  Hello

  I'm leaking memory like PC problem. When I put my cursor over the text, it highlights it, and if I put my cursor on an icon he drags it everywhere. I tried restarting several times and even go into safe mode and yet the problem presists.

  system of care in a few words:

  I have a Toshiba satellite laptop running Windows 7 x 64 bit and an AMD Radeon graphics card and a quad core CPU. I have Java installed and my ESET antivirus. My anti malware program is Malwarebytes anti-malware.

  Thank you and have a nice day :)

• [Bug] Extra large leak of great resources and crash Windows Media Player (WMP) and music collections.

  The installation program:

  Windows 8 Pro x 64.

  WMP 12.0.9200.16420

  Question:

  In the trial of an extra-large music collection (~ 148 000 songs, mostly VBR *.wma) default WMP x 32 app will cause a memory leak upward to 1.5 GB in the Task Manager and then "hang" corrupt the database as it attempts to interview and initially to build the database.  The application itself will lose its bmp controls (they're going black when you place the cursor or spend on them with a mouse) when he hung.

  This is not a regression, happened to Win7 x64as well.

  Previously, it was necessary to create two scheduled tasks that would launch WMP every 5 minutes. and that would kill the process every 40 minutes. If the program would be terminated before fleeing corrupt the database.

  We had hoped that MSFT would do some better load/stress for large media libraries test to see the availability of retail.

  Please try to repro and fix, thank you.

  I also noticed that there is a serious memory leak in WMP 12 on Windows 7/8. Specifically, WMP loses memory each time he reads album art that is incorporated into a music file. Could be the leak even like what you feel?

  After finding the exact cause of the leak, I was able to lead to a workaround that I have included in my plugin WMP Tag Plus . This work around has not been officially published yet, but if you are interested, I can send you a version of the plug-in for you to try. You can contact me via the email address on my site.

• Tablet draws a leak out of the screen directly to the left, whenever I have down Flash CC

  My TS-6608 Turcom / Oh P608N Tablet (people say that they are the same model and I tried both the original driver P608N installation and driver installation Turcom TS-6608 slightly modified for Windows 10 Turcomdrivers)

  draws a line from leaking out of the screen directly to the left whenever I have support with my pen pressure instead of my way of drawing. In Adobe Photoshop CC, it works perfectly fine. Why is this happening and how can I solve this problem?

  A line for every time I press. It is the only blue because that's the color of pen, I had chosen. This happens with the pencil tool and the Brush tool. I happen to run two monitors. Flash is open on the right monitor but I tried to swap around, drop down to a monitor, and it doesn't seem to change. I don't know if this is specific to my tablet or a problem with the program.

  

  It seems that there is a split second after the contact where it does not read my travels before putting in the left straight down.

  

  

  In Flash CS6, there seems to be a similar problem. When I press down, the first point shows but it stops to record the pressure down almost instantly even if I continue upward with the pen pressure. He holds the State pressed down but is not to follow the movement. With my mouse, I can then move around to draw the path, but it is not picking up the pen.

  In Flash CS3, it goes the same way as Flash CS5.5 where appears a point, it will not save the press which took place or release of the pen tip. If I move the mouse after pressing the pen, I can drag it around the same way. The problem seems to be that flash is not just reading presses pen continues but I don't know how to fix it. In other programs, it seems to work very well (Paint, Photoshop, etc.)

  Another thing I discovered is that if I have another program that is not selected in the active window flash but try to draw in flash using the Brush tool and then he reacts appropriately, but the second I drop the brush stroke and let Flash CC 2015 be the active window again it does not recognize my movements.

  I think it might be a simple driver issue.

  ANSWER:

  There seems to be a bug in the driver Turcom code. If you disconnect a monitor then you can normally draw in flash. What happens with two monitors, it's that the pen cursor position instantly repositioned correctly when you press down. Because I was drawing on my right monitor, it tended to be left (maybe because thought Flash that I worked on monitor 1 or something).

  I have an e-ticket with Turcom as a permanent solution, but for now, simply using a monitor works fine.

• Smart memory leak of Plugin

  Hello

  I'm writing just my first plugin smart - so far, I just write regular plugins. My first test was pretty simple, he just had a single slider ranging from 0 to 1 and filled it all out with black, white or gray the appropriate hue.

  However after the cursor to scrub back and forth several times all locked up. Task Manager to open (which took some effort) has shown that AE had eaten all of my memory. Running in the debugger, I found thatcalling filling consumed approximately 8 MB of memory, and then between the return of my AE chip make event and the call to free my AE pre_render_data had consumed on an another 8 MB of memory. Each cursor movement resulted in an another 15 MB or more be consumed and with breakpoints deleted making slowly slide from one end to the other consumed a few hundred MB.

  Then, I changed my plugin so that it completely ignores both made smart and smart prerender events. He has literally done nothing but return PF_Err_NONE. Always AE accumulated memory use. I still get 10 or 15 MB of memory leaks for each render event.

  Have you ever seen this type of behavior before? Is there something I need to make a smart plugin that I did not need to do before that could cause this problem? If necessary, I can post my sample code. I use Visual Studio on Windows 8.1 with AE CC 2012.

  Phil

  It turns out that this is correct behavior. There is no bug. It's just the AE cached results.

  I downloaded the SDK of 2014 AE CC and built the plugin Smarty Pants here. I still see the same behavior. AE eats memory that I move the cursor backwards and forwards. However if I go to Edition-> Purge-> memory usage then falls to about 200 MB. By increasing the allocation of memory for other applications under Edit-> preferences-> memory & multiprocessing, I can limit the memory usage to an amount that avoids crashing the debugger.

• Metric of the influence of the size of the PGA and UGA County cursors

  Hello!
  
  If I have the right to understand,
  the child cursors County growthing indirectly affects the size of the PGA and UGA,
  If that's true, how to receive absolute metric (* GA, no Shared Pool)?
  
  
  Thank you

  Hi Paul,.

  To be more precise, I refer to the implicit cursors that are stored in the library cache. Please do not confuse with the cursors that are defined explicitly in pl/sql.

  For each identical sql statement, oracle will create the shared cursor (library cache), if this is the first time that the statement is then executed as said previously it will create the cursor in LB, so is the second time, the same SQL statement is executed then oracle will share already created the cursor to the second statement.
  Under normal circumstances for each identical instruction, there are 1 parent and 1 child of the cursor.

  Consider the example next where the sql statement appears to be the same but do not share already created cursor and therefore it must create a new.

  Session executed following queries:

  Select the name of the employee; -> It is that first time sql is executed, then oracle will open a new cursor. In a specific cursor, you have the code sql and other execution information.

  Session B executed after the request:

  Select the name of the employee; -> Here statement SQL makes sense even with above but this will create a new cursor, so already open for session A will not be shared. Note here that the SELECT is uppercase, then oracle think it's the different statement and thus create a new cursor.

  It's an example where difference in uppercase letter oracle thinks it's a new statement. But there are other schenarios where the same situation occurs.
  Another reason for cursor not shared are in V$ SQL_SHARED_CURSOR.

  Although oracle database running in the situation where the sliders are not shared, then this can lead to performance impact hugh like lock in shared long, shared pool leak memory pool, library catch latch etc.. More important, which will require another cursor important to eliminate memory to place a new

  I hope you already know, what is analysis difficult. If this increase the situation of hard analysis, which may further affect the performance.

  Let me know in case of doubts

• cursor jump after update of the Sierra

  After update of last week to Sierra of MacOS, I noticed many times randomly my cursor will jump erratically. I noticed several times why in an application like Photoshop Adobe or Illustrator but today it happened so that in Safari. Its very rare that gives me trouble with troubleshooting myself. Maybe one, two times a day.

  Before Sierra, I have not noticed any issues with the trackpad when his flat on a desk. In the past maybe noticed a little problem here and there if on my lap or on an angle, but this small current problem seems to have started with Sierra.

  Clean your trackpad

• Problem of cursor or mouse

  Since the upgrade to Sierra, the cursor or the mouse does not work properly with Lightroom CC 2015.7, version "safe Sierra. It could be a problem for Adobe but Lightroom and Photoshop have been updated for Sierra and only Lightroom has the problem. Oddly enough, Photoshop works OK. In addition, the Sierra of Lightroom, 2015.7 security update, worked perfectly with El Capitan, without any problem of cursor or mouse. So I guess it might be problem Sierra or Lightroom allowing customers to loss. The Magic Mouse and the Mighty Mouse mice are problematic.

  The main problem for me is that the cursor has become limited in controlling sliders and tone curve points.

  Someone else?

  Yes, the same problems here. With the help of Macbook Pro 13 '' end 2014 on macOS Sierra & Lightroom 2015.7. Strange behavior when using the sliders and the points of the curve.

  Do not forget that what was already a problem once after a LR update - so I guess it's at the end of the Adobes.

• Touchpad cursor gets hard to control "woozy"

  Recently, I went back to using my Mac Pro 2009 after using a Macbook to the past two years for most. I upgraded to El Capitan first, and I decided to start a new account because I've been migrating the same account for 20 years. So all is cool enough for most.

  I had used a magic with the MacBook Pro touchpad because I hated the portable computers clean touchpad. Having become accustomed to the use of the touch pad, that I decided to use it with the Mac Pro. I use the touchpad, even for the last two years.

  Here's the problem: I have not yet identified which triggers it but what is happening is that the slider will frequently and suddenly become what I can only describe as 'under the weather', and I hope it makes sense. It becomes slow and its response and tends to overcompensate sometimes I have to be very careful and precise and slow in my movements when it's like that because if I use my hands the way I would normally be the cursor will overshoot.

  It does not have it for long periods of time, but he does not often. And it makes me a little nuts. Any ideas?

  Really?  No one has an answer here?  I'm going crazy... and now my stylus is dead, so I am forced to use the touchpad! (I can't use a mouse because of repetitive stress injury)

  If anyone has any ideas, please share!
