• Obsolete backups are not deleted

  Hello

  My script for the work:

  @echo off
  
  SET ORACLE_HOME=D:\Oracle\11.2.0
  SET ORACLE_SID=XXXX
  SET NLS_LANG=GERMAN_GERMANY.WE8MSWIN1252
  SET NLS_DATE_FORMAT=yyyy-mm-dd:hh24:mi:ss
  SET BACKUPDIR=D:\db_backup\rman\XXX
  SET SCRIPTDIR=D:\db_backup\scripts
  SET LOGDIR=D:\db_backup\logs
  
  %ORACLE_HOME%\bin\rman.exe target / cmdfile=%SCRIPTDIR%\rman_command.rman msglog %LOGDIR%\%ORACLE_SID%_backup.log
  
  exit
  
  

  The rman_command.rman file:

  sql 'alter system archive log current';
  crosscheck backup;
  crosscheck archivelog all;
  delete noprompt obsolete device type disk;
  delete noprompt expired backup;
  backup database plus archivelog delete input;
  exit
  
  

  So I want to keep only the backups that have less than 3 days. And the older then 3 days should be discarded. But my problem is, that sometimes rman stops just delete old backups. And keeps all old backups. I also noticed that overnight stop to delete older backups is the same when the database has rebounded. For example, if the database has rebounded on June 28, 2015, then after June 28, rman always delete the backups. So I have now all bakups since that data. What I also noticed that rman stops remove the actual backups but don't not continue delete the backup control file.

  Is this a bug?

  OK, I got it. There is a corruption of block in the database which prevents the full backup at some point in its execution.

  Guys, thanks a lot for your help!

• Delete obsolete backups

  I have redundancy for 1, I understand that now only current backup set must be valid and all backups must be now be in the list of obsolete backups. But it is not yet with me, when I give RMAN > obsolete report; order it show only the precedent of obsolete backup and not showing any old backups in this list. So I physically delete these backups, but when I give RMAN > list backup summary; or RMAN > backup overlap command, showing all old backups that I was deleted. I work in catalog mode. What is the cure...
  

  RMAN> show all;
  
  RMAN configuration parameters are:
  CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
  CONFIGURE BACKUP OPTIMIZATION OFF; # default
  CONFIGURE DEFAULT DEVICE TYPE TO DISK;

  HI Werner,.

  Yes you are right.

  What backup set is deleted by using OS commands. Backup set becomes expired if we run 'overlap backupset' and delete obsolete will not erase this info from the catalog.

  to do this need to run 'delete expired backupset '.

• recover a deleted account? -Hotmail account has been deleted for not being active

  my hotmail has been deleted by you, for not being active, I guess, but I use it for my ps3 account, so it is important to me, can the hotmail, be found?

  Hello

• BlackBerry Smartphones dSimple 4-digit password is not being recognised & observed Timeout of security not defining re-creation of my attempts to try again

  Hey all the... I retired my Storm 9530 some time ago (my fingers are too big for the touch screen and key of BB contact confirmation system to the key light blue is lost in my porkers, so needless to say I didn't have much success with the storm) and currently active (on TELUS Mobility) a Tour 9630 I received from a friend as a scrap... I have set a password 4 digit simple twice now and have wiped twice the phone because it will not recognize the password I've carefully matched to each time.  Frustrating!

  Both times I had the number of attempts to set password on 3, the second time, I deliberately set the security option timeout to 1 minute... thinking that if I waited entry password incorrect one or two attempts (in which case it was me the fat-fingering entry somehow), the number of attempt would be at least 3 reset again... She apparently does not exist , so I'm not sure what the purpose of this function is to - 0558PST27NOV12 FFF edit - OK, Security Timeout is how long a period of inactivity to allow before the automatic locking device.

  I searched for 'lock' here and came across an answer to a Post of Thread that describes making attention to the key hold them used when setting the password... I can only think of two ways to enter figures: using the 'alt' key and then press the appropriate number pads, or, using the "sym" key and scrolling for the numbers right, one by one... However, now, during my third session of creation of password on the freshly wiped phone, I realize that because the entered password characters are masked, I can simply seized letters instead of numbers all along, a capital letter followed by three lowercase letters - is probably what its likely?  I can't believe it didn't come up here several times - edict of 0558PST27NOV12 FFF - OK, I decided that all the characters went to letters and must have been all lowercase password connection PC GUI-based unlock success of the device.

  in any case, this policy of scorched earth to wipe my phone whenever I get incorrect password (somehow) seems harsh... I would like to have a simple lock on the device security, but not at the risk of it being deleted so arbitrarily... If I lost that a dishonest person found, chances are they would just wipe it and get this trigger themselves or, if they were honest, but curious, I'd get it back... wiped.

  Is there another way to lock and unlock the phone w/o to the draconian measure wipe?

  Thank you, FFF

  Hello

  It is excellent that you have discovered, by searching on this site, the solution to your problems of password entry. Play well!

  As for your desire for a less drastic locking... feature that would require a separate application to do (I don't know if they exist). After all, the BBs are safer mobile devices available... to diminish the ability of the device lock feature would reduce the overall security of the device.

  In my humble OPINION - the device itself is a mere commodity. The data on it, however, are priceless... and protect the data from prying eyes is essential for safe keeping the device in place. Fortunately, RIM provides several FREE methods to backup your data to be used to restore any catastrophic event. All users of BB to use these methods.

  Good luck!

• What is to remove all obsolete backups triggered in Oracle 11 g DB

  I have a question as to when removes all obsolete backups triggered in Oracle 11 g DB. We changed the retention policy RMAN for 10 days to 14 days in our facility.

  Hopefully, my question is clear.

  Please get back with the answer to my query.

  Concerning

  First of all, I would never run my backups in OEM.  When the crisis comes to 02:00, I don't want to ever more parts to be involved in the recovery.

  Second, the only thing approaching a 'trigger' of deletion of backups is if your backups are in the FRA... rman will be, at the time of the execution of a backup... try to remove backups obsolete if necessary to free up space in the FRA.

  Other than that, oboslete backups are only deleted in response to a direct order to REMOVE OBSOLETE.  This command can optionally (as indicated by TigerDBA) includes a rule of the obsolescence of execution, or it may depend on the configuration stand.

  Another thing to note is that the backups are NOT marked as obsolete.  They are EVALUATED for obsolescence in response to a command DELETE OUTDATED or OBSOLETE REPORT.

  And one last thing to not is that any recovery has to start with a full backup.  It would be the most recent full-time (or level 0 incremental) backup before the point in time you need to recover.  This means that the most recent full-time (or level 0 incremental) backup will never considered as obsolete, no matter what age there.

• Why my RMAN to archivelog backups do not end in ORACLE_HOME/dbs?

  DB version: 11.2
  Platform: Solaris 10
  
  I noticed that the elements of rman backup containing archivelogs end in $ORACLE_HOME/dbs directory despite using the format parameter. This happened for the level 0 AND level 1 backups.
  
  I know that the backup files result in $ORACLE_HOME/dbs when you forget to specify the FORMAT. But the FORMAT is included in my Level0 and level 1 Scripts as shown below. Is there something else wrong with my scripts L0 and L1?
  
  Here's my Level0 and level 1 backup scripts
  
  
  -Level0

  run
  {
  allocate channel LEVEL0_TBLQA device type disk;
  crosscheck backup;
  delete noprompt obsolete;
  backup as backupset incremental level 0 database format='/u04/dbfiles/RMAN_bkp/tblqa/TBLQA_full_%U_%T.bkp' plus archivelog delete input;
  release channel LEVEL0_TBLQA;
  }

  -Level 1

  run {
  backup as compressed backupset incremental level 1 database format='/u04/dbfiles/RMAN_bkp/tblqa/TBLQA_L1_%U_%T.bkp' plus archivelog delete all input;
  }

  This DB uses the control as a catalog file.

  backup as backupset effective additional 0 database format='/u04/dbfiles/RMAN_bkp/tblqa/TBLQA_full_%U_%T.bkp' more entered archivelog delete;

  backup as backupset effective additional 1 database format='/u04/dbfiles/RMAN_bkp/tblqa/TBLQA_L1_%U_%T.bkp Tablet ' more archivelog delete all entries;

  This is because the format that you specified is good only until the database backup (backup format compressed backupset effective additional 1 database "... ") and not for the log archiving in your script. Therefore, the archivelog backups stored in the location of $ORACLE_HOME/dbs and the backup of the database gets stored in the format location you mentioned in your RMAN script.

  Instead, you can use as below:

  run
  {
  allocate channel LEVEL0_TBLQA device type disk format '/u04/dbfiles/RMAN_bkp/tblqa/TBLQA_full_%U_%T.bkp';
  crosscheck backup;
  delete noprompt obsolete;
  backup as backupset incremental level 0 database plus archivelog delete input;
  release channel LEVEL0_TBLQA;
  }

• iCloud iOS 9.2 backup still not fixed!

  So I was prey to the backup could not be completed problem and waited for Apple to get a fix and I was happy to see this problem mentioned as one of the bugs addressed in iOS 9.2, BUT she was not really fixed!

  Now my phone is not backed up at all after all the geniuses of Apple has informed I have delete older backups to iCould and try again, my MacBook storage is too small to carry my 128 GB iPhone backup and now if my phone dies for some reason, my life went with it, and well more than she!

  I tried save my iPhone to external storage, but Apple won't let you do that cause us are freaking slaves and not free to do what we want, so now that I hope that they would finally listen and solve this problem which has already been mentioned several times!

  I've been through exactly the same thing. Have tried to reset network settings, off iCloud signing out and to iCloud, soft reset, change what's sustained upward and recently before 9.2 erase the old backup.  Now I'm in the same situation have iPhone 6 more 9.2 128 GB with no backup icloud saying could not finish and last backup ever!  I have not managed to get a backup of my iMac, but really really wanted to do a reset factory and restore unless I'm sure that it will solve the problem.

  Apple please help.  You have acknowledged the problem, but apparently the attempt to remedy with 9.2 didn't work.

• Time Machine backups do not complete

  My main problem is when I start a Time Machine backup, it works quickly for an hour or two and then slows down to a crawl and never ends.

  I'm on 10.11.1.  I reformated my Time Machine backup disk to try to begin to clean up two or three times and I have the same problem.

  It started when I updated to El Capitan.  My original backup has been corrupted.  I reformatted the drive and now I am at this point.

  These must be run as administrator. If you have only one user account, you are the administrator.

  Please launch the Console application in one of the following ways:

  ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  The title of the Console window should be all Messages. If it isn't, select

  SYSTEM LOG QUERIES ▹ all Messages

  in the list of logs on the left. If you don't see this list, select

  List of newspapers seen ▹ display

  in the menu at the top of the screen bar.

  In the upper right corner of the Console window, there is a search box to filter. Enter the 'Start-up' (without the quotes). You should now see messages in the log with the words "departure * backup," where * represents one of the words "automatic", "manual" or "standard".

  Each message in the journal begins with the date and time when it was entered. Note the time stamp of the last 'Start' message that matches the start of a normal backup. Now

  DELETE THE WORD 'Start' TO THE TEXT BOX

  so that all messages are showing and highlight the newspaper at the same time, you noted. Select the time-stamped messages since then until the end of the backup or the end of the log if it is not clear. Copy to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

  If all you see are messages that contain the word 'Start-up', you clear the text field.

  The journal contains a large amount of information, almost everything that is not relevant to solve a particular problem. When you post a journal excerpt, be selective. Don't post any more it is requested.

  Please don't dump blindly thousands of lines in the journal in this discussion.

• Windows 7 backup does not not on my new external HDD

  I have a HP Pavilion dv4-1435dx laptop with Windows 7 above. I just bought a new external hardrive, ST905004EXA101-RK Seagate Expansion Portable 500 GB.

  I tried to back up my computer to the ext hd using windows 7, but whenever I do, I get this message:

  "Windows backup could not create a zip file. This could be because the drive on which Windows is installed does not have enough space or it could be a temporary error. Make sure you have at least 400 MB of free space and try again. »

  This has happened at least 5 times now, and he always says that he has not supported my computer successfully. This means - there is sometihng wrong with the hd position? If there is, I don't think it's a question of size as the troubleshooting of the message suggests, since the hd station is new and empty data.  (Yes, I delete all data from the backups half completed after each time windows tried to back up my computer).

  I thought maybe it was a question of the zip/compression program that I am using, Stuffit. While I downloaded the free trial version of Winzip, restarted my computer, but still it will not save properly.

  Anyone know what is happening?

• WIN 7 backup has not been successful.

  Original title: WHEN is it SAFE TO SAVE DATA ~ WIN 7

  Twice immediately after a backup of my data in Win 7, I get messages that my Back-up cannot be entirely refunded.

  My apologies ~ I do not remember the exact legends but they indicate that my backups were not entirely successful.

  1. after a system restore

  2. after having Defraggling the computer.

  Is there a period of time, after which, if I run backups, that these messages can be avoided?

  Windows7 64-bit

  Thank you.

  Rajdeep.

  Rajdeep salvation,

  Yes, it could be the Piriform Defraggler which is to detach the restore points. Error or the events in the event viewer (Volsnap could not develop because of a user input) also happen when there was not enough disk space in the box Diff for Volume Shadow Service take a snapshot. Due to lack of disk space in the Diff area, the operating system automatically deleted the snapshot taken.

  Check out the link to increase the Volume Shadow-diff area and check if it solves the problem:

  http://TechNet.Microsoft.com/en-us/library/dd364636 (v = ws.10) .aspx

  Also, try to uninstall Piriform Defraggler and check if you still receive the error message.

  For reference:

  Run a check disk operation to see if there are bad sectors on the disk at the origin of this problem. Check out the link to run the tool:

  Important: the data available on bad sectors may be lost when chkdsk attempts to repair your hard drive.

• CS5, installed from a backup does not work in the new iMac w / El Capitan; the discs moved

  My 2011 iMac has a failing hard drive. I downloaded a full backup, including the CS5, in a new iMac running El Capitan. None of the Adobe programs will run, even after I installed Java SE 6 & restarted. A Setup from disks, starting with Acrobat 9 Pro disc and after dragging the applications icon, gave me this: "the operation cannot be completed because one or more required items be found.» (Error code - 43) »

  I deleted programs meeting CS5, rebooted and tried to load again from the disk of Acrobat 9 Pro. After dragging the applications icon, I got this: ' the finder cannot complete the operation because some data in "" cannot be read or written. ". (Error code - 36) »

  Updated his computer at El Capitan my wife and charge of Java SE 6, and his CS5 still works. What can be done in my case? Thanks to all in advance!

  Download from a backup will not work.

  You must install it.

  https://helpx.Adobe.com/Creative-Suite/KB/CS5-product-downloads.html

  But CS5 wil cause a lot of errors on El Capitan.

  They simply are not (fully) compatible.

  Just search for it on the forum, you will find a lot of threads.

• obsolete backups

  Hi all
  
  I put my retention policy to recovery of 8 days windows;
  
  I have backupset in 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 OCT.
  
  13 OCT, now obsolete report. I get no obsolete backup found.
  
  What is the reason for which the backup of the Oct. 3, 4 and 5 are not listed as obsolete?
  
  Kind regards

  Mseberg has explained very well... just add an extra touch.

  When using the incremental backup keep this rule:
  The last backup is always a FULL BACKUP (level 0) regardless of the number of incremental backup or backup the Archivelog you have. Which is applicable to the 'window of recovery' and 'redundancy '.

  for example redundancy to 3:
  We have 50 incremental backup, but you must be at least 4 full backup to any backup becoming obsolete.

  for example redundancy to 3 days:
  We have 50 incremental backup, but must be at least a COMPLETE BACKUP of the first hour of a hypothetical recovery point-in-time in this recovery of backup window become obsolete.

  # added October 15, 2012 15:35
  Keep in mind: the Archivelog backup / backup incremental level 1 or above is always the continuation of the last incremental backup. So if you have a backup of level 0 and level 1 backup and two backup level 2 tree... We don't have only one backup that have a set of backup incremental level 1 or higher.

  IE if you have lost your backup incremental level 0... any incremental backup that depend on this backup level 0 will be garbage.

  It is a concept that we should always keep in mind. In this way, that we will be ever confused about retention policy.
