• difference between online redolog files and archived log files

  What is the fundamental difference between archived log files and online redo log files? .. .plz keep things simple as m a newbie

  Online redo log:

  Redo online Oracle log files are filled with records of restoration by progression. A record of remake, also called entrance to roll forward, is composed of a group of agents of change, each of which is a description of a change to a single block in the database. Each instance of an Oracle database has an associated online redo log to protect data in case of failure of the instance.

  See here,
  http://download.Oracle.com/docs/CD/B10500_01/server.920/a96521/onlineredo.htm

  Archived redo log:

  Oracle Database allows you to save files to one or more destinations offline newspapers filled with repeat groups, known collectively as the archived redo log. An archived redo log file is a copy of one of the members of a group of redo log filled.

• Recovery of database of old backup and archive log file complete

  Hi expert Oracle!
  I encountered the problem where my oracle database restore.
  
  In my case:
  -My version of the database: 10.2.0.2
  -J' have a full database backup (01 - Nov)
  -J' have all the archived since (01 - Nov-> 05 - Nov) log file
  -My database down to 05 - Nov with disk error (no data file, not again...).
  -I have no backup RMAN (01 - Nov-> 05 - Nov)
  
  How to restore my database to 05 - Nov?
  
  Thank you

  After you RESTORE the DATABASE,

  Use the VALUE UNTIL to set the Point of recovery to 05 - Nov, and then RECOVER the DATABASE
  OR
  Use the SQL command "RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL" that will keep asking 'future' ArchiveLogs backup.

• LOG_ARCHIVE_FORMAT and old log files

  Hello
  
  in 10g documentation, it is said:

  LOG_ARCHIVE_FORMAT initialization parameter, using %t 
  to include the thread number as part of
   the file name, %s to include the log sequence number,
   and %r to include the resetlogs ID 

  What is the point of having resetlogs ID in the name of archived newspaper? How he would leave to avoid replacing old log files?
  
  Thank you.

  Very easy. From 10 gR 1, including the resetlogs Id made recoveries by resetlogs much easier than before.

• imageFORMULA CR-180 check the log file to scan

  Hello

  I work with an imageFORMULA CR-180 check Scanner and when executing a good amount (longer than 100) of the controls, I noticed that the scan control stops and a pop-up window appears on the Analysis ToolPak asked if I would like to replace my log file and start over.

  The software that I use is called "Utility scan for CR-180II" and the log file contains the information of MICR line controls scanned, as well as the date of the analysis, and the location of the file to the images captured from the parser.

  Log file options under "Options-> MICR data parameters.

  What I do, it is by clicking on ' no, I want to overwirte the file ", stop the scan, moving the log of the 'old' file, restart the scanning and backup to a new log file.

  Is there anyway to work around this problem and record continuously in the same log file?

  Is there a memory limit on the scanner?

  This is the Web page of the scanner that I use:

• Try to uninstall Earthlink Accelerator but I get an error message that INSTALL. LOG file cannot be found

  I got earthlink.net as a dial-up internet service and changed to netzero.net, so I decided to uninstall all software from Earthlink.  Everything uninstalled great, except for the Earthlink accelerator.  When I go into control panel > programs > earthlink Accelerator > uninstall I get an error message: cannot find INSTALL. LOG file.  I did a search as an administrator to INSTALL fond. Not and the LOG file to get anything.  How can I find this file so that I can uninstall Earthlink accelerator.  I'm very technically inclined but still can't find the problem.

  We will try to remove the registry key associated with Earthlink accelerator.

  Before that, please make a return register by following the steps in http://windows.microsoft.com/en-in/windows-vista/back-up-the-registry

  Now, perform the following steps:

  Type regedit.exe in the Start search and press on enter.

  Go to the following location and delete the keys. (Also, note the location of the Earthlink accelerator installation file and delete them)

• Expectations extended on synchronization of log file while the parallel writing journal is fine

  We have 9.2.0.8 as experiences of long waits on the database log file sync (average waiting time = 46 ms) while waiting for the log file write Parallels is very good (average waiting time is less than 1 millisecond).

  The application is of type middleware, it connects to several other applications. A single user in a single application action train several requests to send back through this middleware, so he needs response time of db in milliseconds.

  The database is quite simple:

  -It has a few config tables that the application reads but rarely updated

  -She has table TRANSACTION_HISTORY: the application inserts records into this table using Insert einreihig (about 100 lines per second); each insert is followed by a validation.

  Records are kept for several months and then purged. The table has only column VARCHAR2/NUMBER/DATE, no LOBS, LONG, etc. The table has 4 non-unique single-column index.

  The average line length is 100 bytes.

  The load profile does not appear something unusual, the main figures: 110 transactions per second average transaction = 1.5 KB size.

  The data below are to 1 hour interval (purge wasn't running during this interval), physical reads or writes physical rate is low:

  Log buffer is about 1.3 MB. We could increase the log buffer, but there is no log buffer space waits, so I doubt this will help.

  
  

  Newspapers in recovery have their own file systems, not shared with the data files. This explains the difference between waiting avg on parallel writing of log (less than 1 ms) file and db file parallel write (27 ms).

  Restoring logs is 100 MB, there are about 120 journal switches per day.

  
  

  What has changed: the pads/validations rate grew. Several months ago there were 25 inserts/validations per second in the TRANSACTION_HISTORY table, now get us 110 inserts/validation per second.

  
  

  What problem it causes application: due to slow down the reaction of the basis of the application (Java-based) requires discussions more and more.

  
  

  MOS documents on synchronization of log file (for example, 1376916,1 waits for troubleshooting "log file sync") recommend to compare the average waiting time on synchronization of log file and the log file parallel write.

  If the values are close (for example log file sync = 20 ms and log file parallel write = 10 ms) so expectations are caused by nits IO. However, it is not the case here.

  
  

  There was a bug (2669566) in 9.2 which resulted in underreporting lgwr parallel time of writing to the log file. I was talking about September 2005, during which the bug was present in 9.2.0.6, reported 10.1 fixed in: file parallel journal written (JL Comp) it is possible that your problem IS written to the log file.

• That redo log files waiting?

  Hello Experts,

  I read articles on the log redo and undo segment files. I was wondering something very simple. That redo log files waiting in there? It stores the sql statements?

  Lets say that my update statement to modify 800 blocks of data. A unique single update statement can modify different data 800 right blocks? Yes, it may be true. I think that these data blocks can not hold buffers to the log to roll forward, right? I mean I know exactly what to do redo log buffer and redo log file. And I know that the task of backgrounding LGWR. But, I wonder if she she holds the data blocks? It is not supposed to hold data like cache buffer blocks, right?

  My second question is, rollback isn't effect to restore the newspaper to the right buffer? Because it does not need log buffer for effect do it again. Conversely, the restoration; statement is included in the restore log buffer by progression when someone isse, am I right?

  As far as I know, rollback interact directly with UNDO TABLESPACE?

  I hope that I have to express myself clearly.

  Thanks in advance.

  Here's my question:

  My second question is, rollback isn't effect to restore the newspaper to the right buffer? Because it does not need log buffer for effect do it again. Conversely, the restoration; statement is included in the restore log buffer by progression when someone isse, am I right?

  As far as I know, rollback interact directly with UNDO TABLESPACE?

  Yes, where else would the undo data come from? Undo tablespace contains the Undo segments that contain the Undo data required for the restoration of your transaction.

  I can say that rollback does not alter the data of the log buffer rede to the past. In other words, change vectors will be remain the same before restoration. Conversely, rollback command is also recorded in the log file of restoration by progression. As the name, all orders are saved in the REDO LOGS.

  I hope that I am wrong so far?

  Not sure why you even the buffer log roll forward for Rollback? This is the reason why I asked you it was for, where occurs the dose the cancellation? And the answer for this is that it happens in the buffer cache. Before you worry about the drivers of change, you must understand that it is not serious what contains where as long as there is no transaction recorded in the operating of the Undo segment table. If the operating table indicates that the transaction is longer there, there must be a cancellation of the transaction. Vectors of change are saved in the file log roll forward, while the restore happens on blocks of data stored in the file "data" undo blocks stored in the undo file "data".

  At the same time I read an article about redo and undo. In this article process transaction is explained. Here is the link http://pavandba.files.wordpress.com/2009/11/undo_redo1.pdf

  I found some interesting information in this article as follows.

  It is worth noting that during the restore process, recovery logs never participate. The only time where redo logs are read is retrieving and archiving. This is the concept of tuning key: redo logs are written on. Oracle does not read during normal processing. As long as you have sufficient devices so that when the ARC is reading a file, LGWR's writing to a different device, then there no contention for redo logs.

  If redo logs are never involved in the restoration process, how is it Oracle will then know the order of the transaction? As far as I know it is only written in redo logs.

  I have thoughts very amazed to Aman.

  Why you ask?

  Now, before giving a response, I say two things. One, I know Pavan and he is a regular contributor to this forum and on several other forums Facebook and two, with all due respect to him, a little advice for you, when you try to understand a concept, to stick to the Oracle documentation and do not read and merge articles/blog-posts from the web. Everone, which publishes on the web, has their own way to express things and many times, the context of the writing makes it more confusing things. Maybe we can erase the doubts that you can get after reading the various search results on the web.

  Redo logs used for the restoration, not to restore. The reason is the redo log files are applied in sequential order, and this is not the case when we look for the restoration. A restore is required to do for a few blocks away. Basically, what happens in a restoration, is that the records of cancellation required for a block of data are sought in the reverse order of their creation. The entry of the transaction is in the slot ITL of the block of data that point to the necessary undo bytes Address (UBA) using which oracle also knows what that undo the blocks would be necessary for the restoration of your transaction. As soon as the blocks of data will be cancelled, the ITL slots would be cleared as well.

  In addition, you must remember, until the transaction is not qualified as finished, using either a commit or a rollback, the cancellation of this data would remain intact. The reason for this is that oracle would ensure that undo data would be available to make the cancellation of the transaction. The reason why Undo data are also recorded in the journals of recovery is to ensure that in the event of the loss of the cancellation of the data file, retrieving them would be possible. Because it would also require changes that's happened on the blocks cancel, restore the vectors change associated with blocks of cancellation are also saved in the buffer log roll forward and, in the redo log files.

• Analysis of the log files from vCenter

  Hello, a virtual machine has been removed in our area, and I need to analyse what/how it happened. Unfortunately, the vSphere and vCenter log files have since turned. However, in regards to the vcenter, I have backups of the log files, and these have been restored. When you look at the log files I don't let you content or find the name of the virtual machine when you perform a search.

  Can anyone tell how to examine the log for a deleted VM files?

  Thank you

  The entry in the journals of vpxd looks like this:

• To access the log file entries in Oracle 10 g with respect

  Hi all
  How can I access log files entries in oracle 10 g (linux) by questioning... and where it is stored to the origin
  Thank you...

  user8843114 wrote:
  In fact, I do not know the difference between the log files and Audit information... are they equal?
  I know how to obtain audit information... that is to say using a table sys.aud$... is it possible to access the log files if the two above are not equal

  It really depends.

  "Log file" is a generic term. Most of the time it refers to record information in a flat file outside the database. And there are many types of log files. An Oracle database's redo log files and archived log files. An application will have its own log usually on a middle-tier server. An Oracle database can be configured to generate an audit trail in an external file or in a database table (SYS. AUD$). And there are dozens of other ways that people could use the term "log file."

  Depending on how you use the term, it may or may not be possible to access the information in the log file of the database. You will need to know what log file you were interested and where this log file. If the log file is accessible to the database, it would probably be possible to use external tables or same UTL_FILE to access information, depending on the format of the log file.

  Your elapsed time is about 2000 seconds (31: 55 rounded up) - and your log file sync time is 10,000 - which is 5 seconds per second for the duration. Otherwise your session count is about 250 at the beginning and end of snapshot - so if we assume that the number of sessions is stable for the duration, each session has undergone 40 seconds synchronization log file in the meantime. You have saved roughly 1 500 operations in the meantime (0.91 per second, about 13 per cent of restorations) - so synchronize your time log file was on average more than 6.5 seconds by validation.

  Regardless of how you look at it, this suggests that numbers of synchronization of the log file are false, or you had a temporary outage. Given that you had some expectations occupied buffer and control file write expects about 900 m/s each, the hardware failure seems likely.

  Check log file parallel write times to see if this helps to confirm the hypothesis. (Unfortunately some platforms report liog, parallel wriite time of the files properly for earlier versions of 9.2 - so this may not help.)

  You also 15 enqueue waits with an average of 1.2 seconds - check the enqueue statistics in the report section to see what enqueue it was: if it was for example (CF - control file), then it also helps confirm the hypothesis of material.

  It is possible that you had a couple of resets of material or something like this in the meantime that stopped your system quite dramatically for a minute or two.

• Mail creation of massive log files and stop the synchronization with the server

  Since the upgrade to El Capitan (10.11.1), Mail presents two problems persist:

  (1) it generates massive log files, e.g. 2015-12 - 03_IMAPSyncActivity.log these files regularly exceed 10 GB and block Mail and freeze the Mac. Mail can be over 8 GB of RAM. Once removed, Mail recreates the file and fills again, ends up doing more massive files that must also delete.

  (2) mail stop sync with my different IMAP e-mail servers. The only solution I've found that it completely delete the or the e-mail accounts and reinstalls the account. It works for a day (or even a few hours) before it just stops the synchronization, even if a connection test shows he connects with the server. This problem seems to occur on two e-mail accounts separately on two different servers / hosting companies, but not on my Gmail accounts.

  These two problems occur on both my iMac (21.5 ", mid-2011, 2.5 GHz Intel Core i5, 8 GB RAM) and MacBookPro (13', mid-2011, 2.5 GHz Intel core i5, 4 GB RAM).

  Full of ideas gratefully received!

  Thank you!

  Please take these steps to remove the mail folders 'sandbox '.

  Step 1

  Back up all data.

  Triple-click anywhere in the line below on this page to select this option:

  ~/Library/Containers/com.apple.mail

  Right-click or Ctrl-click on the highlighted line and select

  Services ▹ Reveal

  the contextual menu.* A Finder window should open up with a folder named "com.apple.mail" selected. If this is the case, move the selected folder - not only its content - on the desktop. Open the window Finder for now.

  Restart the computer. Launch Mail and test. If the problem is resolved, you may have to re-create some of your e-mail settings. Any writing paper custom that you created may be lost. Ask for instructions if you want to keep these data. You can then delete the folder that you moved and close Finder.

  CAUTION: If you change the content of the sandbox, but leave the folder itself in place, Mail may hang or starts any. Remove the tray to sand everything will be rebuilt automatically.

  Step 2

  If step 1 does not resolve the problem, repeat with this line:

  ~/Library/Containers/com.apple.MailServiceAgent

  * If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

• AoE3 cannot create log files and will not run.

  AOE3 I installed on my machine. The game is stored on an external hard drive that is almost new and has yet to give me any problems. Whenever I try to launch the game, I get the following error "could not create the log file. Ensure that you have all rights in the directory where the Age of Empires III, and that you have available disk space. \n Erroe: access denied. »

  I am the only user of this computer, my account has full administrator access and there is more than a terabyte of disk space. I don't knopw not why there is no problem running this game - especially as all the other files on the road very well works.

  Any help would be greatly appreciated.

  Thank you.

  Delete the log file, "Age3Log.txt", which could give this error message from My Documents\My Games\Age of Empires 3 'folder.

  Try to delete this file as an administrator, and then click Connect.

• Files dump debugging and log files to install in the disk cleanup window

  The two points above appear in my disk cleanup window, and I wonder if it is o: k to remove. The first occupies a space of 283 KB and the other 2537 KB. The description of these two files in the disk cleanup window is "files created by Windows.

  I have a second question: I have about 5 GB left as free space on my hard drive of 'C '. If this is considered sufficient, or should I get more? I am a senior retired and only use the computer for basic items.

  I have a computer Dell Dimension 4100 with Service Pack 3 for Windows XP - Home Edition Operating System - desktop, 111 Pentium with 930 MHZ, 20 GB hard drive and 512 MB RAM. The file system is FAT 32.

  Thank you very much for your cooperation and your response.

  "Debug dump files" are copies of the contents of your computer's memory.

  When a program crashes, it will sometimes "dump" all or part of the
  contents of the RAM to a file on your hard drive. The file is useful to
  a technical support person who tries to understand why the program
  crashed. (Most of the tech support people have no idea what to do with a dump
  file.)

  Unless you have been asked to submit a dump for inspection file, feel free
  to get rid of them.

  Setup logs files are "log" installation of a program. If you
  Watch a (they are really just text files - open with Notepad) you will have
  see that they give a blow by blow description of how the program has been
  installed, glorious detail.

  If a program does not properly settled, the Setup log will tell you what that
  was wrong. If you have not had a facility wrong, do not hesitate to ditch
  These files as well.

  On the question of how much free space on the disk is enough... There is no
  standards. 15% of your drive must be empty in order for Windows
  The Defragmenter built into the work. In addition, it is to you.
   
  Your processor is another story. It's not easy to find effective security
  software that will work on a P3. Even if you only use the computer
  for the basic elements, an internet connection is pretty basic for a online
  criminal to find you.
