• Redo log entries to the online redo log files

  Hello

  I'm a little confused about the redo log entries.

  I learned that LGWR writes redo log entries in the SGA, in redo log files in the following situation:

  -3 seconds after the last validation

  -redo log buffer has 1 MB

  -redo log buffer data 1/3

  When I take a transaction and if I change the wrong data, I have to cancel this transaction BUT the right now,

  What happens if the LGWR writes redo log disk entries?

  Is the bad transaction committed at all times?

• bottleneck during the passage of the redo log files.

  Hi all
  
  I'm using Oracle 11.2.0.3.
  
  The enforcement team has indicated that they are facing slow at some point.
  
  I followed the database and I found that at some passage of redo log files (not always), I am facing a slow at the application level.
  
  I have 2 son since my database is CARS, each thread has 3 groups of multiplexed redo logs the FIU, with size of 300 MB each.
  
  Is it possible to optimize the switch of the redo log files? knowing that my database is running in ARCHIVELOG mode.
  
  Kind regards

  Hello

  Yes, Oracle recommends 1 validation by 30 calls from users or less. Of course, every database is different, so this rule cannot be taken too literally, but in your case, this rule seems to apply. In any case State, 900 undertakes seconds it looks like a very large number and the need for a high number of transactions should be questioned. You should talk to your analysts/application management/enterprise architect if warranted - that is to say if the application does in fact almost 2 000 business transactions per second.

  What about DB CPU: here is a link to a blog that I wrote on this subject, it should help to better understand this number:

  http://Savvinov.com/2012/04/06/AWR-reports-interpreting-CPU-usage/

  But briefly: DB processor isn't a real event, it is simply an indication that the sessions are on CPU (or waiting for CPU) rather than wait on i/o requests or events in the database. It is not necessarily a bad thing, because the database must perform tasks and he cannot do without loading the CPU. It may indicate a problem in two cases: when the CPU usage is close to the limit of the host (OS stats section indicates that you are very far from there) or when the CPU is a % of DB time - in the latter case, this could mean that you are making too many logical reads due to inefficient plans or analysis too. In any case, this does not apply to you, because 20 percent is not very high a number.

  Other items in the list of the top 5 deserve attention, too - gc buffer busy acquire, gc current block busy, enq: TX - line lock conflict.

  To summarize, your database under a lot of stress - whether it is the legitimate workload, and if this is the case, you may need to upgrade your hardware later. There is chance that it isn't - for example a high number of runs may indicate that rather than to bulk operations database code using PL/SQL loops, which is a big performance killer. Check "Top SQL by executions" about whether or not this is the case.

  Good luck!

• SIZE OF THE REDO LOG FILE

  
  Hello

  I got an error message when I add me new group. log files I searched and found the answer on the form. Ago 4 M minimum size of 11 g R2 log file size.

  My question is why a log file size depends on DB_BLOCK_SIZE? This parameter is set to the component structures of memory that create an instance when a log file is an operating system file that depend on the version of the OS not DB_BLOCK_SIZE.

  Thank you.

  SQL >

  You are assuming that the redo log block size is the same as the database block size. This is not correct.

  The error indicates that 8192 is the minimum number of blocks of a redo log file. The documentation states that the minimum size is 4 M. For example, you can deduct your redo log block size is 512 bytes.

  Here's some more information about the size of redo log, the documentation block.

  Unlike the database block size, which can always be between 2 K and 32 K, redo log default files to a block size that is equal to the size of physical sector of the disk. Historically, it is usually 512 bytes (512 b).

  Some new large disks offer 4K sizes byte (4K) to increase sector efficiency improved format and ECC capabilities. Most of the Oracle database platforms are able to detect this bigger sector size. The database then automatically creates files redo log with a block size of 4 K of these discs.

• What is the role of the archived in an incremental backup redo log files?

  I want to know, to which RMAN reads what block of data is changed after the last incremental backup.
  and what is the role of the archived in an incremental backup redo log files?
  
  Please guide.

  Hello

  First Querstion response->
  Each block of data in a data file contains a system change number (SCN), which is the SCN of the last change to the block. During an incremental backup, RMAN reads the RCS of each block of data in the input file and compares at the checkpoint SCN of the incremental backup from parent. If the RCS in the block of input data is greater than or equal to checkpoint SCN of the parent, then RMAN copies the block.

  2 - the archived redolog files are required for the restoration of the online of rman incremental backup in a consistent state.

  How to boot in Safe Mode and Clean worked for you?  Not at all useful?

  You said about this 2 weeks ago?

  Yet once, I fell in this place and the time and effort wasted because MS Answers forums invite to no system information when a new question is asked - but I digress.

  Update of security 908513 is included in Service Pack 3 update.

  Since forums MS Answers asks you any information from system when a new question is asked, we don't even know what Service Pack you have.  If you have SP3, you already have the update.  Two weeks and we don't know what is your Service Pack, what is your antivirus/antimalware environment...  We know that you have XP Pro 32-bit however.

  What you're likely to have is an extension of the Explorer Shell with a malfunction, and you can usually understand as follows:

  When the Windows Explorer (not Internet Explorer) is wrong (especially when right click), begin to suspect third-party add-ons explore extension.

  Those who would be the Explorer extensions that do not belong to Microsoft.  This means that extensions that you have added.  Solution Explorer extensions are generally well and installation of certain applications will install extensions from Explorer solutions for you, give you a choice and sometimes they can be added without your knowledge when you install the new software.

  Solution Explorer extensions are sometimes added as a new right-click option, you see on folders and files (like the scan of this file, open that file, play this song).

  If there is something in particular that you do during exploration that you know will be the cause of the problem, which will help focus on the problem and the help that you suddenly know, when you have found and corrected.  If you can get there when you want it, make an adjustment and then there is no message the next time you don't do anything, you do, you have found and corrected.

  If you can really achieve almost everytime you do a right-click and choose something like delete or copy, you're well on your way to understand.

  First of all you need a way to see what modules explore you have installed now and a way to turn them off (not uninstall them) so you can understand that we are at the origin of the problem.  You can have a lot of extensions not installed Microsoft don't even know you about.

  Download ShellExView here to see what Explorer extensions you have loaded:

  http://www.NirSoft.NET/utils/shexview.html

  ShellExView does not install anything on your computer, simply of runs and displays.

  After launching ShellExView, under Options, choose "Mark non-Microsoft Extensions" and extensions not Microsoft will be pink, clear, but on some systems which is a difficult color to see, so click on display, choose the columns and move the column Microsoft closer to the top, so you can see on your screen without having to scroll left and right.

  Click on the column header for Microsoft sort display (by clicking on the column of Microsoft) then all the non Microsoft extensions are on top and easy to see.

  Non-Microsoft extensions would be things you have added (non-Microsoft) and are what you should be suspect.

  You can also Google the name of a suspect add-on and see if there is any success about the errors with the extension and to what other people have done on it... Maybe just to get an update of the program that adds the suspicious extension.

  You can Google something like:

  Explorer XP crashing

  (you must complete your suspect on behalf of add on)

  See what kind of search results hits you get and are looking for solutions or situations that sound like yours.

  I'm not a defender of trial and error, but I can't think of another way to do...

  Right click and disable the extensions one at a time non-Microsoft keep a list so you can enable them again later if you wish. The result of the change is immediate and no reboot is necessary.  Test your failure condition.

  If you recognize all the extensions that have been added or recently downloaded, start with these first.

  Disabling the extension does not uninstall the extension - it is just disabled.

  Disable them one at a time until your right click on do not generate an error, then restart and test again.  You have disabled the last extension would be suspicious.

  You can also just disable all non-Microsoft extensions, restart and allow them one at a time until you find the one that generates the condition.

  The hope is that you will find an extension that caused the error, and then you can figure out what on this subject - either uninstall it or see if you can get an update of the author of the extension of their web page.

  I have not your problem, but I can when you toggle extensions, the extension is immediately turned off, to disable an extension does not require a restart, but if you find the problem, I reboot and retest in all cases to be sure that the problem has disappeared.

  If you post your non-Microsoft extensions list, maybe someone will recognize it as a potential problem.

  If you find the offending extension that's the problem, please let us know what it is that I can add to my list.
