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. Is triggered manually by remove all obsolete QuickTime-> manage backups current OEM or is it automatically triggered whenever RMAN backup is done?

Hopefully, my question is clear.

Please get back with the answer to my query.

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  They are EVALUATED for obsolescence in response to a command DELETE OUTDATED or OBSOLETE REPORT.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.

    But what I see in the created log file by running the script that is today:

    And yesterday's paper shows that only "automatic" backup files have been deleted as follows:

    2 objects deleted

    RMAN >

    And when I run after a command, I see a lot of obsolete backups (until December 18):

    RMAN > obsolete report.

    And when I run the same command that is in the script on the RMAN prompt, RMAN removes all obsolete backups without problem:

    RMAN > delete noprompt obsolete;

    Backups are stored on the disk and then moved to tape by the storage team. I'm only responsible for keeping backups of 7 days on the disk. I have to make sure that obsolete backups are deleted so that there is enough free space on the NAS share allocated for backups. Right now it's full of 71%.

    Why RMAN is not delete the rest of the files?

    Please notify.

    Best regards

    And it won't delete. It is a normal behavior of RMAN. Read carefully this line:

    A recovery window is a period of time that begins at the present time and extends backward in time to the point of recovery.

    Example, today is December 26, and your retention period is 7 days... If you go back 7 days, which would be December 19... RMAN will not delete backups because you need on 15 December (backup Sunday level 0) to make the recovery. Lets say if it removes all backups before December 19, then you cannot recover the database with only 19 December backup, you must certainly level 0 backup for backup, which is December 15. So once again,

    A recovery window is a period of time that begins at the present time and extends backward in time to the point of recovery.


    Make sure you read this link, this is a great example explaining your scenario:

  • How to remove all the day archivelog backups?

    Hello

    Oracle 10 g 2 on 64-bit RHEL.

    Backup strategy:

    • There will be a level 0 of the database every Sunday and level 1 backup every working day.
    • Archivelogs will be saved up every 30 minutes.

    Q: How can I remove ALL archivelog backups that were taken that day there (every 30 minutes) just after the success of the backup of level 0 or level 1?

    I want to remove them because they will be of no use after the backup of level 0 or level 1 (am I right)?

    Best regards

    The idea of removing the archivelogs tape/disk backup will not only affect point in recovery time, but also be against the concept of RMAN retention policy. If your backup retention is of 7 days, RMAN manages backup element (Archives of newspapers/data/control files) are obsolete.

    Command below will delete backup logs to archive more than 1 day:

    DELETE the BACKUP OF archivelog until TIME = ' sysdate-1'. '.

  • first of all, last backup previous, next, remove, run, find.

    experts,

    am on jdev 11.1.1.4.0

    in jdeveloper's buttons as such as first of all, last backup previous, next, remove, run, find.

    What is my question?

    is it possible to do?

    I don't want these buttons,

    instead of the buttons - I needed icons. to do the same.

    for explanation,

    One for example:

    In jdeveloper, we make some changes in the design or can the coding part.

    then, after our hand moves to keep these changes.so icons press to save each of them.

    It comes from my point of view.

    When the user do any input in my ui.he want to save data by pressing not buttons. by pressing save icons. icons of disk (i.e.). in our toolbar

    I want to make the same operation to save icons instead of Save button.

    like wise

    I want these cancellation of the operation, redo, first, last, next.previous. No button. only the icons. perform these operations.

    If it is possible can you show the way.

  • My iPad 2 is very slow.  I removed all unused applications and erased from history.  What can I do else?

    My iPad is very slow.  I removed all unused applications and erased from history.  What can I do else?

    A disclaimer clause.

    I make no warranty, express or implied, that my own procedures return EACH older iPad to a usable state, running.

    Try all of the following conditions:

    Try to reset all the settings in the settings under general app and in the right column under restore.

    Try stories reset and delete/reset the caches in all web browsers you use.
    If you use Safari, these features may be in the application settings under Safari.
    Other browsers have their settings inside the running application itself.

    If your iPad has been activated for iCloud, in the application settings under iCloud, to the right, under iCloud Drive, type in iCloud drive and make sure that Safari is off to save data from Safari to iCloud by car.

    Also, under iCloud in the application settings, in iCloud Drive, turn the feature off saving for all other desired apps DO NOT the data automatically on iCloud drive.

    If you are using Safari is always causing issues.
    Try changing / using web browser third another, different.
    I do not use iOS Safari too much more because I found it cause me headaches on some Web sites, regularly, to visit.
    I commonly use another third party browser, perfect browser (there are others that can suit your style better web browsing, so look all first to see what third-party browser may work better for you) and I have never experience many questions that Safari was originally.

    In the settings app, under the Safari settings panel, tap lightly on the Panel in the right-hand turn off / disable Safari Suggestions.

    In the application settings tab general, right under the spotlight sesrch, try disable the search under the applications who really don't need a research, as some games, remote controls, apps that are really useless to be searched, etc., in order to reduce the list to Spotlight search.

    Try to turn the reduced movement.
    This is found in the application of settings in the general tab, in the left panel.
    In the right panel, look under accessibility, look to reduce the Motion and turn this feature "On".
    You should see a significant performance increase on all models of iPad 2, 3 and 4.

    In the application settings under the general tab, in the right column, search background App update and enable this setting to "off".

    Try a reset of your iPad by simultaneously pressing buttons Home and sleep/wake button until your iPad goes to the dark and restarts with the Apple logo, then release the buttons.

    Good luck!

    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.

    Time Machine backs up your default boot partition.

    Hello

    You can take a safe backup.

    After you create your first backup, Windows backup will add new information or changed to your subsequent backups. If you save your backups on a hard drive or network, Windows backup will create a new backup, full for you automatically if necessary. If you save your backups on CDs or DVDs and could not find an existing backup disk, or if you want to create a new backup of all the files on your computer, you can create a full backup. Here's how to create a full backup:

    1. Open backup and restore by clicking the Start button, clicking Control Panel, clicking system and Maintenance, and then clicking the backup and restore.

    2. In the left pane, click on create new, full backup.
