• What are the 'additional Control Point', 'current log tail' and RBA

  I myself messgae in the alert log file

  Incremental checkpoint up to RBA [0xe.58bfe.0], current log tail at RBA [

  In reading articles on Oracle and the Oracle documents, I have also come across these three terms much

  Incremental checkpoint
  current log tail 
  RBA

  I really want to know what they are in a short and clean definition. Lengthy discussions are devoted to "Incremental Checkpoint" in the url

  http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:19311485023372

  But I got confused.

  There are many different types of control point - the thing they have in common is that they require the database writer to write disk blocks (see the last part of this post: http://jonathanlewis.wordpress.com/2007/04/12/log-file-switch/).

  The "additional control point" is simply the name given to the event of control point which is scheduled to occur every three seconds and allows dbwr to write of disk blocks that have first changed more than a certain distance in the past.

  In this context, RBA means 'redo the address bytes' (address of block redo only sometimes) identify a location to a redo log file.
  The 'end of the newspaper' is the latest ARI redo entry written in the restore log file growth.

  In a control post additional dbwr derives a value for a Resource that represents a previous point in time and written on the disk of the data blocks that have been changed by generated redo before RBA and have not been written to disk since this change.

  Depending on the configuration of your settings file the previous RBA may be derived in a time lag, a volume of roll forward or the number of blocks of data that have to be modified for the IRA at the end of the paper (actually).

• Confused about "additional control Points.

  Hello

  I'm confused about this sentence from database Concepts 11g Release 2 (11.2)

  Additional control points

  An additional control point is a type of thread control point in part intended to avoid writing a large number of blocks online redo log switches. DBWn checks at least every three seconds to determine if he has to do. When DBWn written stamps Sales, it advances the position of the control point, causing CKPT write the position of the control point to the file control, but not for data file headers.

  I thought that a checkpoint is written datafileheader and controlfile, this happens for example after a switch logfile - right?

  So, why not in the case of additional control point? For best performance?

  Additional control points to reduce the time to recover, as more data is committed to the files of data, right?

  There are many types of control points. One that will be updated on the headers of data files would be a complete control and would be applicable to the entire base. The additional control point is induced to keep on enhanching a counter that would ensure that only certain limited stamp Sales would be recovering. That's why a moment of the additional control point, data file headers are not being updated. Control file is probably updated with a "pointer to disk" which mentions the point up to which the dirty buffers are written in files (from the buffer cache) data and where to start the recovery, if necessary. Log file switch will cause a thread control point which, for one instance, would be considered a Global checkpoint only. The additional control point would be for various other reasons such as setting a value for the parameter Fast_Start_Mttr_Target etc.

  Specify the control point table in the global file is every time that you restart your replica he get the overall point check table form file.

  What is the exact error message received when the problem occurs?

  Methood 1:

  Auditor of file system (CFS) scan to fix all of the corrupted system files. To do this, follow the steps in the following link:

  How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

  http://support.Microsoft.com/kb/929833 

  Method 2:

  You can start Windows Vista by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  I suggest to put the computer in a clean boot state, and check if the problem persists, see the link:
  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
  http://support.Microsoft.com/kb/929135
  Note: See step 7; Reset the computer to start as usual after troubleshooting is performed.

  Method 3:

  You can temporarily disable the security software and check if the problem occurs. Check out the following link to do the same thing:

  http://Windows.Microsoft.com/en-GB/Windows-Vista/disable-antivirus-software

  Warning: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  I hope this helps! Let us know if you need more assistance.

  If you have any software backup as totalrecovery pro 9 or norton ghost, they prevent you from creating a manual restore point.  I have 9 pro full recovery and everything I do is to disable the Recovery Manager when I want to create a manual restore point.  There is no problem with system restore points created they work very well it is the manual of who are the problem.

• "Windows Media Center cannot detect the IR control cables, which are necessary to control the set-top box. Fixing parts IR that supports the IR control cables and then try again. IR HARDWARE NOT FOUND ".

  Original title: when setting up Windows Media Center, I get the error message: "IR hardware not detected".

  I have an internal TV Tuner that has been installed by HP, when I bought recently a "computer build-your-own." (According to the control panel Device Manager, my tuner is a Win TV HVR 1290, made by Hauppauge). The computer came with Windows 7. While installing Windows Media Center, after setting up the TV Signal (on channel 3) I am able to see a video thumbnail on my computer screen. I am also able to change the channel using my remote control U-Verse (not the Windows remote control supplied with the computer). So far so good! I then hit next and get the following message: "Windows Media Center cannot detect the IR control cables, which are necessary to control the set-top box. Fixing parts IR that supports the IR control cables and then try again. IR HARDWARE NOT FOUND ".  After you receive this message, the installation procedure is completed. I called HP that support intalled the tuner. They had not the slightest idea what to do. I then called Hauppage customer (manufacturer of TV Tuner). They said that I need to plug one end of the IR Blaster cable that shipped with the computer in a slot in the back of my computer (they told me which slot). They said so to run the IR all the way cable to my cable box and the other end of the cable to my cable box of band. They said it was necessary to be able to use my Microsoft Remote to instruct the box to change channels (cable IR stuck on the box). I told her that I did not use the Microsoft Remote, I could change the channel with my U-verse remote (that I preferred to use anyway). He said that it took the cable on the band decoder in order to remove the error message and the installation of Windows Media Center. I then called U-Verse technical adapter who informed me of their set-top boxes (made by Cisco Systems) do not have the ability to receive signals IR IR Blaster cable (or any othe IR signal source). Microsoft is apparently not understand how U-Verse set-top boxes are designed to work and sells a product incompatible remote control/IR. My question is this: How do I set up Windows Media Center, in order to avoid getting the error message "IR hardware not detected" when you install Windows Media Center and just use the remote control of the U-Verse that I prefer to use in the first place. Once understand you this point, please send the information to HP, At & T U-Verse and others. Thank you.

  Ron, I have something for you!

  and for all the people who have this problem :)

  Hi, I had the time of IR not detected in Windows 7 Ultimate with a TV wonder 650 card and a box of digital adapter from Verizon for my PC... Go on the road to installation and after the Media Center channel search, choose manual configuration. Choose the aerial signal (I aso picked after this analog) l. After he sought more, he finds no channels.  Do not be afraid. Just accept it and go to the main settings page in the Mediacenter. If I remember correctly, then select TV Guide. Choose Add channel. I added the channel 3.

  Since my Verizon box has no IR for the computer, I added the channel 3 for the media Center and I change the channels with my Verizon remote. All my stations in the Verizon box go to Channel 3.

  The story here is so, for some reason any Windows detects that only my box channel signal TV and you must manually configure the media center on the air, then go to settings and add the channel you want in the guide.

  Why the guide TV control which channel you can tune is beyond me, but the scanner locks all channels, it does not detect. they must be added manually in the guide.

  My TV works and looks okay now.

  It actually works!

  the only problem is that it is not in HD

  but there is something
