• 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.

• Folight - SQL Server 2008 R2, DBSS - error log file size

  Hey guys,.

  Try to understand why the alarm DBSS - size of error log is shooting. Why does foglightr not read these log files? Is this a mistake in my setup?

  "The size of the file SQL Server log Archive 6 is 2 685,00 KB, which is too big for the scan. Analysis is disabled.  "

  Hi Daniel,.

  There is a default setting of 1 024 KB for this rule in order to avoid possible performance issues by reading a log file that is too large. You can change the limit by checking the boxes next to the instances of SQL Server in the data base Control Panel and proceed to the Administration of the Agent. Select alarms and then DBSS - size of error log and change the threshold. You can try to 3000 as a value.

  Kind regards

• archived log file

  Hi all
  I have a question, the issue is that log file Archives consist only validated data, or it can contain a data.thanks uncommitted to the answer in advance.

  Your question is answered, so clerks of the newspapers contain archives and data constantly. Simple example, if you run long DML statement like update in running or insert in this case all by running this transaction you can get more than archivelogs always the transaction is not completed, but will generate the archivelogs.

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

  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...
  
  -Yasser

  The server process (RFS) remote file writes data to redo in files newspapers awaiting restoration by increase the standby database, application services log can recover again waiting for redo log files, as they are filled.

• Why the JPG file size decreases when Lightroom writes meta data?

  Lightroom uses the files sidecar XMP for meta data history for RAW files. When writing the metadata (e.g. tags) to JPG files, they are written directly in the header of the file. This should leave the image information in the file intact. However, the file size decreases (about 0.02 MB) when Lightroom writes metadata for the original JPG file. As far as I could see, the image information remain unchanged and no other information in the header is deleated, but why decreases the size of the file then (I expect to increase slightly or stay the same)? I work with RAW files for most but sometimes I just versions of the files to work with JPG and I don't want to lose any information.

  Thanks in advance for your answers.

  Kind regards

• 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.

• Archive log file bloat - is currently out of cold back to the top of the best strategy?

  Hi friends,
  
  I have a database 10 g. / WinSvr2003 making heavy spatial processing of the Oracle.
  
  Previously, I ran the database in log mode archive and sparked a lot of files to archive log. 150 G (the worst week).
  
  I got fed up with backups (incremental) RMAN night heavy and put the database in a mode non - archive journal. (I was also worried about the time to get the data back out of band).
  
  Now, I come to launch the next nightly bat file: -.
  
  oradim-stop-sid DEV - syspwd *.
  
  del /S /Q D:\oracleBackup\DEV\*
  
  XCopy/e D:\oracle\product\10.2.0\oradata\DEV D:\oracleBackup\DEV
  
  oradim-startup-sid DEV - syspwd *.
  
  ----------------------------------------------------------------------------------------------------------
  
  1 week ago - when I arrived-in the morning the database had not restarted due to an inconsistency of data file.
  Recover the database fixed.
  
  I guess he had something that this necessary in the redo log files? (its mode no - archive).
  
  I have a DB 24/7.
  
  This cold offline backup is the best strategy to avoid the bloat of log file archive
  
  I can always use RMAN and do not back up files of newspaper Archives? How can I make sure that it is a consistent RMAN backup if she has no access to archive the log files. (I just use RMAN after an immediate stop - restart?)
  
  How instruct you RMAN is not to get the files to archive log?
  
  DATABASE INCREMENTAL LEVEL 0 BACKUP; <-this leaves archive the log file out of the backup.
  
  Thanks in advance.
  
  See you soon,.
  
  AA
  
  P.S. This is my first post on this forum. Yes!

  If you
  a. make a backup of the database CONSISTENT (that is to say in MOUNT but not OPEN) with RMAN
  b. do not save the ArchiveLogs
  c. yet the ArchiveLogs to create the database in ARCHIVELOG mode,

  You can still use the combination of consistent backup and ArchiveLogs generated since the backup database (assuming that the ArchiveLogs are still on the disk) in the method of 'Refresh '.

  In other words, RESTORE (but not RETRIEVE and OPEN) the database of the RMAN.
  Using sql RESTORE DATABASE with the HELP of BACKUP CONTROLFILE to 'Updating' then apply ArchiveLogs for what is just restored.

• File size never changes from original file.

  Sony A72 images all show 24meg size of the file after the import.  When I edit and convert to tiff or jpg, they show again 24 meg file size.  Now the new file uncompressed raw of Sony also shows 24 megs, but in reality is about 49 megs.

  It's 24 million pixels, not megabytes!

• The Android custom native window Archive (.zip) file size limit?

  I'm having a problem today trying to download my storefront customized to the Native Android App DPS constructor. My .zip contains some of the important assets for use in offline mode, but the .zip is only 39MB. AppBuilder DPS doesn't seem to like this great archive. I have another application built with success and this archive is 1.1 MB, while there is a limit that it will accept.

  There is no error message or warning present, simply, it does not accept my .zip file to download.

  How to work around this problem?

  The limit for all the additions in App Builder for all viewers zip file, is 30 MB. You need to resize your assets down, so the total zip size is less than 30 MB.
