• Real - Time apply a few times using archived log file

  Hi all
  
  I have a doubt about the real time apply in Oracle 10g 10.2.0.4 version where the arch process has been configured on the primary and standby has been configured for maximum performance with real time mode applies.
  
  But in the alert log file shall I use to find the message below rarely

  Media Recovery Log /oraclearch/oraarch/ctdr/5548.dbf
  Media Recovery Log /oraclearch/oraarch/ctdr/5549.dbf

  So my question is why the archived files are applied pending have been configured for real-time if applies where it should apply only from logs in mode standby online.
  
  Also I can't find any information on the eve of the database in the view v$ standby_log that these pending online log files have been archived in the column archived, then how to find how much data was written by process Srl rfs...

  DBID would be here.
  These groups of waiting for redo log files can contain either the thread 1 or thread2, several threads are used in RAC environment.

  In general architecture, once if any log switch (or) redo log is full then they will be sent in files archive, then it will be assigned to new files redo log. here in the primary redo log file, you can see the current, active, inactive state so now.

  During the real time applies, every time that data written to the primary log files, the log of the time same writer will be active and which will be assigned to the redo log file... not redo log file, you have to say standby redo log waiting for database.

  average not assigned here, this standby redo log file, can be used for the next time, perhaps earlier status as 'active '. Each time standby redo log file is active DBID so only you can see.
  If its in unassigned it will be inactive, once again if any new allocation then it will become active. similar chain / loop. This is perfectly normal behavior.

  UNASSIGNED - online redo log has never been written for. It comes to the State of a newspaper of restoration by progression that has been added, or just after a RESETLOGS when it is not the log during recovery.
  ACTIVE - Log is active but is not the current journal. It is necessary for the recovery of the failure. It can be used to block recovery. It may or may not be archived.

• control real time apply log on the database after synchronization

  Hi all
  
  I want to check the timestamp of applied newspapers archived on stanby database. How should I check that?
  
  My dataguard link was broken for some time, and during this time, many transactions happened on the primary database. Now, when the link came synchronization has happened in a few hours and ultimatly transport and app gal has become 0. But now I want to check real time taken for tranporting newspapers and apply them on the standby database. Is there a way I could do it easily...
  
  Thank you

  This script written by Yousef Rifai, I found here http://www.dba-village.com/village/dvp_forum.OpenThread?ThreadIdA=34772&DestinationA=RSS could be just what you need (executed on the standby database):

• Motion/opacity (yet) does not when you use the time remapping effect

  OK: Here's my meat. This bug has been around for CS3 and CS4. I was hoping this would be fixed with the arrival of CS5, but apparently it still has not been resolved.

  If you use the time remapping effect in the body, you can not use the other features of keyframing, such as movement or opacity. If you do, the video simply disappears. Rendering will not help either. The only way to get the opacity of the function is to overlay a video black bar on the top of the element (or any other cache of color if you like fantasy) and have the opacity on this clip in reverse work. How to get movement in these clips remapped time to work is still somewhat a mystery to me...

  Has anyone found this tedious, boring/irritating?

  So, when can dear Adobe, we expect a fix for this? If all goes well before CS6.

  Thank you very much.

  Richard

  Yes, it's a real annoying bug.
  Simple around - after work you time-remapping your clips, nest (control-click on the clip and select 'nest'), then you can change the opacity normally.

• RunTimeException when you use the timer and TimerTask.

  In the switchNext() method, it changes an image and some text in a Vertical management. When I run the application, I get a RunTimeException. However, when I have not used the timer and tested the method switchNext() with just a button method worked perfectly. How can I make it work with timer or another class that he will call every 30 seconds?

   time = new Timer();
  TimerTask task = new TimerTask()
  {
  
  public void run()
  {
  
      switchNext();
  }
  };
  time.schedule(task, 10000);
  

  It would be useful to know what Exception you actually get.

  However, I think that it is indeed related to the fact IllegalStateException the TimerTask is running in the "bottom", and you try to update your User Interface.

  If you change the code as follows, it will work the method on the event Thread and so he has access to update the user interface.

  public void run()
  {
  UiApplication.getUiApplicat () .invokeLater (new Runnable()

  public void run() {}
  switchNext();

  }});
  }

• How to set up a database of Eve 'apply in real time '.

  Hi all

  11 GR 2,

  Rhel6

  How to set up real-time apply such as the transactions are updated in near real-time to the wait, even without switching to log files?

  For example, we have 1 GB size redo logs and assuming that it will take 1 day to fill these newspapers. This means that our expectation will be entitled to 1 day delay of data?

  This means we lost 1 day of a disaster at the primary data value? because the redo log was not able to move the log files?

  Thank you very much

• cRIO - creation and deployment of real-time independent startup application troubleshooting

  I use cRIO-9024 with a chassis 9112 for a control system. I use LV2011 SP1. When you run the system in development mode (by pressing the run button), everything seems to work properly. When the autonomous real-time construction and running in startup application, something stops working.

  In order to know if the application is running or not, I toggle the user LED on the cRIO using this code:

  

  When I turn off all the code in the main VI except this loop, the application deploys and runs at startup without problem (the LED flashes). I then add progressively more loops that I want to run (by disabling the code less and less), and the problem seems to be in the open FPGA VI reference block. If I disable this block, the slopes of autonomous real-time application (I guess the error 63195, handful of peripheral communication not valid, will spread along the line, but I know that the app works because the LED flashes).

  

  I tried several configurations for this block open FPGA VI and mixed results. For example, if I set it up this way:

  

  The application in real-time to start runs with the reference block opened VI FPGA active but work stoppages as soon as I turn on a code that makes use of this reference in the subVIs .

  Someone at - it an idea of what could go wrong? I have explored the messages thrown by cRIO at startup but can not see the error messages (in fact, the console output is the same when I managed to deploy an application that is running (by disabling the code). I also tried to explore the error logs (via right click on target Utilities > view error log) but cannot decrypt any useful info on their part.

  

  Any ideas will be greatly appreciated.

  Hi kkguner,

  My problem is that the code runs (apparently) ok in development mode, but it seems that, when it is deployed as a stand-alone application in real time, it does not at all. As I was not able to get messages through to watch the console output when restarting my cRIO or explore the Project Explorer error logs or error, I can only imagine what is happening.

  I feel that QFang suggestions go in the right direction, but I've yet to be able to determine the exact cause and the solution of the problem.

  The solution I set it with has been to deploy my application as a source with a start VI distribution instead of as a stand-alone application in real time. You can try this option.

  What I could try when I have some time is to clean my system from LV (whether in mass compilation or by reinstalling completely). I tried a massive compilation of vi.lib and I got a good amount of (UN) insanities, the wrong screws and several other unfortunate messages.

  kkguner, let us know what you discover in your inquiry, or if none of the suggestions solves your problem.

  Thank you QFang and xseadog for your help. Best regards!

• Read a signal scope works in execution to highlight, but not in real time

  I want to get the maximum value of a waveform to a former stretch of Agilent 54622 via GPIB.

  The problem is that I regularly receive a Visa Read error-1073807339 ("timeout expired before the operation is completed") when running in real time, but NEVER in execution to highlight mode.

  The posts here suggests that the calendar can cause the read to run before writing was able to finish. So, I used one - manually controlled while loop, sequence and blocks waiting for try and ultra Structure separated blocks of reading and writing of overlap between them. But it still does not work!

  Suggestions, please? (Thanks!)

  

  If you happen to open the VI I attached, you will see that I use a serial port. This is because I use a USB of Prologix-GPIB adapter to interface with the scope (I don't have an adapter USB of NOR-GPIB). I used successfully this Prologix adapter for over 2 years to connect perfectly with an amplifier to locking SR830 and several other devices, so I don't think that's the problem...

• Real Time Messaging Protocol

  Hello

  I have currently a game online Adobe Flash based and have questions about safety. The game uses Real Time Messaging Protocol to manage messaging chat between players who are gathered in the same room on the game. It was brought to my attention by another player who has been using Wireshark to see what his computer sent back, and it seems that the game sends the IP address of each in clear to all players in a room whenever they said something. The game and its players, were attacked by pirates before so I was wondering concerned how should we be actors? Is there another way the game could handle messaging between players who does not expose our IP addresses? Is there a setting to turn on encryption for this Protocol? I hope I explained it well enough for someone to give me a little help.

  Thanks in advance

  I think maybe they use rtmfp not rtmp.

  It is technically possible to set up a game that allows participants to interact anonymously.  This usually requires a server to which all clients connect and who coordinates traffic between clients.  It is usually expensive.  It is also a design decision that must be made and implemented by the developer of the game.

  You can use a proxy service anonymous to hide your real IP, but that will increase the latency of your gameplay.  There are a lot of services at reasonable prices that will do it for you.

  Everything simply encrypt the traffic won't help to hide your IP address.  Think of it as a letter of transmittal.  I * could * put the address on the letter that I sent you, but write a bunch of garbage on an envelope won't get it to your home.  It's the same with network traffic.  At some point, things should know where to go.

  It might be worth your time, or lower your blood pressure in order to better understand the different vectors by which machines get compromised in the first place.  Hide your IP address probably isn't the most useful technique.  Keep your operating system/browser/Plug-Ins patched is probably a better place to start, and using a set of quality anti-virus/anti-malware tools can be also worth your time.
