• 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.

  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.

• database backup and archiving log

  Hi all
  
  I have two scripts:
  
  Full_db_backup.sh
  ARCHIVELOG.sh
  
  Full_db_backup.sh I have the below
  

  backup incremental level 0 device type disk tag testTAG database plus archivelog; 

  in Archivelog.sh
  

  BACKUP ARCHIVELOG ALL tag  testTAGArch not backed up 2 times; 

  My question;
  
  can I have the below for the backup of the database?
  

  backup incremental level 0 device type disk tag testTAG database plus archivelog not backed up 2 times; 

  and if so the 'saved 2 times; not' it's only for the archivelog? or not 2 times for archivelog backups of database backed up?
  
  Kind regards

  I will still have the below question about backup of control file that you mentioned in the below:

  Other point:
  As you are making copy of your backupset using a padronized tag, I suggest you include current controlfile on your backup, because Autobackup have a default tag and we cannot change it.
  
  So I suggest you do this:
  
  backup incremental level 0 database INCLUDE CURRENT CONTROLFILE  tag 'my_backup' plus archivelog;
  

  I can't do: Configure auto backup device type disc format control in two different places?
  one on my site of the archive and the other at FRA?
  Currently, I have below:

  Configure the control auto backup disc format of type device to "%f".

  You can create a custom script to run at the end of your backup:
  This query above will create a command to get 2nd copy of your automatic backup;

  The below script check the backup strengthened to FRA on autobackup dir on the last 5 minutes... you can change it as you wish.

  SELECT 'backup backupset from tag '||TAG||' format ''/u01/app/oracle/'||TAG||'%U'';' FROM V$BACKUP_PIECE
  WHERE START_TIME > sysdate - 5 /(24*60) and HANDLE like '+FRA%autobackup%'
  

  Suggestion:
  Disable the automatic backup before making a 2nd automatic backup copy;
  Run the command to make automatic backup
  Enable autobackup after 2 do an automatic backup copy;

• Backups and Archives

  I have a doubt about the backups and archives.
  
  My database is in archivelog mode. Then I do a full backup of the database.
  
  RMAN > backup tag = "bk_level0_200809" effective additional 0 database;
  
  What happens with the generated archives the earliest before the backup of the database, I can remove them? or I just need to have the archives generated after the backup?

  After the first full backup, you must only archives.

  Kind regards

• Deletion of backups of level 1 and archive logs

  Hello
  
  Everyone knows that "the retention policy would be applicable on level 0 backups or only full backups.
  
  So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?
  
  And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?
  
  Any suggestion?
  
  Thank you
  Nitesh.

  So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?

  If you have the revoery retention strategy window 1 day and you take backup of level 0 Sat and then consecutive level until Friday 1 daily backup, again on backup sat level 0 will be obsolete previous level 0 backup sat and its seven consecutive level 1 so is found in the archived log alls before this level 0 current backup will be marked.

  Obsolete report will show you alls backup piece and the archivelogs that are marked as obsolete.

  And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?

  What do you mean by backups, undesirable level 1, on what basis you say that backup of level 1 are undesirable?

• Was a backup, and the only file created was mediaID.bin.

  Title of the Moose: I ran a backup and the only file created was mediaID.bin.  That all my personal files, but also the backup system files contain?

  I am running Win 7.  I chose to let Windows choose the files, but I thought he said that personal folders could be saved.  Not sure if.  If this .bin file contains everything, I can choose just to restore personal files from it?  I am naïve.

  I saved on a flash drive.  When the backup finished the only file in the Explorer was mediaid.bin, but when I reinserted the drive he showed several zip files and those that do not contain my personal backups, so all is well!  Sorry for the problems with my idiocy!

• Why archive log file size constantly change?

  I have a question related to the size of the archive log file:
  I constantly receive a different size to the size of the log file archive, of course, they are smaller than to the size of the log file.
  A guru can explain to me: what possible reason could be?
  Thanks in advance!

  It can happen due to several reasons:

  When you perform a manual archive (via ALTER SYSTEM ARCHIVE LOG CURRENT/ALL)
  When Oracle must respect your ARCHIVE_LAG_TARGET (defined in seconds)

  Unless you do a manual check-in, your parameter ARCHIVE_LAG_TARGET is the reason why you see Archives of logs with different sizes as Oracle has archived the redo log as soon as the time ARCHIVE_LAG_TARGET is reached. Even if the redo log is not full, Oracle will always have to archive the redo log.

• backup and archiving of difference b/w

  I am a new user of fast food.
  Is there a difference in the protection and exploitation of archives.

  Hi akhilms:

  The short answer is that archiving is intended for storage of the previously saved data.

  Simplified data protection process is:

  Base server (with volumes arranged into protection groups)-> RapidRecovery-> backup (organized in recovery points)-> various operations of backup validation (mountability, mimicry, checksum verification, recovery points check etc.) -> Consolidation according to the retention policy planning (i.e. keep all 3 days recovery points, an hour for 2 days, then 1 a day for a week to 1 per month for 3 months then 1 per year for 5 years etc.).

  In addition, you can configure replication by using a different kernel of fast food. The cumulative process would be 'copy' the recovery points from the base of the source to the marrow of replication target. These recovery point would be consolidated as well (most of the time on a different schedule from the retention policy).

  If you feel it necessary to keep one or more strings of recovery (recovery points channels begins with a base image) altered by the cumulative process (consolidation) you can archive them. Archiving does NOT require another nucleus of RapidRecovery. Do that enough space with enough available memory (local, network, clouds) to complete the internal procedures Ops ARE / s a reasonable period of time.

• Disable backups iCloud will delete old backups and free storage?

  I need to keep my current backup in iCloud for awhile (maybe a month, maybe more, until I have find a way to download it somehow) and I'm afraid that my phone re-writing it one night if I forget and leave it with wifi at a charge.

  Can someone check and to confirm disabling backups iCloud keeps intact old backups so I have access to them in the future.

  Deactivation of the iCloud backups will prevent only future backups to take place. To delete older backups, you must remove them manually.

  See you soon,.

• How to create a recovery media factory with Dell backup and restore on Windows 10 1.6.2.4 v?

  I got today a Dell inspiron 3521 a customer, without warranty, after some checking, I discovered that the hard disk has errors and needs to be replaced

  No problem, the only problem is... I have no installation of Dell Windows 8 media. The laptop is updated to Windows 10 last year. In programs and features, I see that Dell backup and restore 1.6.2.4 v is installed. When I search the Dell backup or watch all the apps installed I can't find the program. So I can't run the program to create installation floppies

  When I go to:

  program/PC (x 86) / Dell backup and recovery, I see a lot of files and 4 records, but no configuration file.

  So my question is, how do you create a Dell Windows 8 installation media? Can I use after installing the new hard drive, reinstall Windows?

  For good order, I can't, until now still approach the hard drive.

  Who knows the solution to install the software dell of origin on the new drive?

  The application must be updated for Windows 10 - you can get it as a download from Dell.

  However, if 10 is already installed and enabled, you can also manually install WIndows 10 without the need of a product key - that way, however, do retain none of the applications Dell preinstalled on the system (which is not very important, as some of them such as PowerDVD would require a paid upgrade to work with Windows 10 in any case).

• Backup of archive logs

  I have a cron job that backs up complete zero on Sunday.  I have an another cron job beginning level 1 backups, Monday to Saturday.  I have a 3rd cron that runs every 2 hours for each day of the week in order to safeguard the archive logs.
  
  I have concerns with the 3rd cron job.  Lets say the data in the database has not changed in the last 2 hours.  This cron job would always run this script, create another backup rman (taking more space on the server).  Is my understanding correct that rman is not smart enough to know what data has changed during backup of the Archives of newspapers so that the two components of backup are not store duplicate information? The reason why I think it's because the size of the pieces cackup for this archive log backups stop a lot of the time very similar (but not the same) in size.

  Lets say the data in the database has not changed in the last 2 hours

  That you have taken backup the archivelog at 07:00 and the next execution of the annex is at 09:00. Say that there are about 100 archives that have been backed up at 07:00. And from 07:00 until 09:00, there was that no transactions took place, in other words, that the data in the database has not changed in the last 2 hours.

  In this case, RMAN wouldn't be backup archives that have been backed up at 07:00. If there is no generated archives between 07:00 and 09:00, RMAN wouldn't save anything.

  If the archived log was not saved, it will be.
  If the archive log was not saved and is missing, you will get an error.
  If the archived log was backed up, RMAN will not back up again.
