Old problem of backups RMAN

Hi all

I have a problem with RMAN. I have a version of database 10.1.0.4.2
The database is set to be saved with RMAN from the Manager of the company.

"Keep at least the number of full backups for every data file specified" is selected in "Configure backup settings" > policy
and redundancy is set to 7

The problem is, it does not remove older backups! It keeps everything from February 2007...
There are 3600 points under the backup location...

and the strange thing is when I type

RMAN > remove obsolete;

RMAN retention policy apply to the order
RMAN retention policy is set to 7 redundancy
not found obsolete backups


How can I delete old backup files?
There are about 100 GB and I need to open a space!

Thanks in advance

You are probably using RMAN without a recovery catalog database, as well as information on the backups are stored in the controlfile. It remains not forever, but as long as the parameter

controlfile_record_keep_time

Specifies. Default value is 7 days. If the information on your old backups ran.

Remedy:
Try the command

Catalog recovery area;

This should save all of your backups in the controlfile. Then you come back with

delete noprompt obsolete;

You should also

(a) increase the value of controlfile_record_keep_time at 30 or higher
(b) rethink your retention policy (do you really need 7 old backups?)

Kind regards

  • Do not lock - automate the deletion of backups RMAN old day after a success

    Hi all

    Admin: Do not lock this thread. I moved here the database instance based on the suggestion of another Member, and the question to this forum. If you want to lock a thread, lock one in the forum of the database, not this one.

    I am looking for a way to automate the deletion of backups RMAN old days only after the occurrence of a success. At the present time, I have daily backups of L0 via crontab, and I need to create a script that can tell if a successful backup is done, then delete the old L0 if it has. Any suggestions on how to start? I'm stuck in code to see if a successful backup has been performed.

    Oracle 11.2.0.3

    Exadata (4 nodes)

    Linux 5.10

    * a from database forum

    A backup is completed when the backup command is complete.

    You have two 'blocks execution' in your rman script.

    Put the DELETE OBSOLETE between the end of the last execution block and EXIT:

    OUTPUT CHANNEL fs1b;
    OUTPUT CHANNEL fs2b;
    OUTPUT CHANNEL fs3b;
    CHANNEL fs4b;
    CHANNEL fs5b;
    CHANNEL fs6b;
    CHANNEL fs7b;
    CHANNEL fs8b;

    }

    remove the backup noprompt obsolete;
    "exit";

    You also want to do some other household:

    cross-checking of backup;

    delete expired backup noprompt.

    overlap archivelog all;

    delete noprompt expired archivelog all;

  • How to remove the old backup RMAN

    Hello Experts,

    Please English me to remove my old backups RMAN. We act in RMAN backup on a daily basis on the disc. you want to delete the previous day from the disk backup.

    Ideally if your backup is automatic, you need to add a line "delete noprompt obsolete device type disk;" at the end of backup scripts based on your retention policy clean the old not required for backups.

  • Restoring a backup RMAN to a new instance of the database

    Hi guys,.

    I have a problem with restoring a backup RMAN I have with me a new instance of the database. I have with me are:

    1. backup of the SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_. BKP)

    2. backup of the control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_. BKP)

    3. the full backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_. BKP)

    I received these files to a client environment and I need to restore these to a new instance of the database on a local computer. I gave an attempt as follows (in Oracle 10 g):

    1, creates a new instance of the (Test75) database using the Oracle Database Configuration Assistant

    2 SET ORACLE_SID = Test75

    3 connection to this instance with RMAN

    4 tried to restore the SPFILE from the BKP file received.


    I make mistakes and cannot continue. I don't know if I will carry out the correct steps. Please help me telling me how I should achieve this goal.


    Thank you.

    1. backup of the SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_. BKP)

    2 backup of control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_. BKP)

    The first backuppiece resembles a ControlFile and the other looks like a SPFILE'

    > I get error and cannot continue

    What is the error?  (I assume that you have tried to restore the O1_MF_NNSNF_SPFILE_BU_92DVGW9H_ SPFILE. BKP

    Note that you must also SET the DBID before restoring the controlfile

  • UNDO Tablespace backup-RMAN

    Hi/team champions,
    I'm confused in full DB Backup RMAN why CANCEL tablespce is included even we include also archive logs.
    in a Word?
    Why UNDO tablespace backup is necessary while taking backup RMAN?

    Kind regards
    Shitesh Shukla

    If I do not want to include the UNDO tablespce in my backup

    What happens if I took only backup files except CANCELLATION n TEMP

    NOT an option. You must include UNDO. 11g has optimization in order to safeguard an Undo tablespace.
    10 gr 2 what you pourriez do is

    1. create a new Undo Tablespace
    2. position yourself in the new Undo Tablespace
    3. check that the old Tablespace Undo is no longer in service - confirm that there is no transaction active in the inside undo segments
    4. remove the old Undo tablespace
    5. start your RMAN backup

    You run the risk of
    a. wait long to step 3
    b. ORA - 1555 s for users once you drop the Undo tablespace to step 4.

  • Old problem with Spotlight and Word .docx files

    There is an old problem with Spotlight not finding the Word .docx files.  You can find old discussions about it since 2008.  But despite this problem being old has never been resolved.

    The essence of the issue is that Spotlight relies on a variety of software modules for the index files.  Projector selects the module suitable for each type of different file of the index.  These indexing modules all have the suffix of file .mdimporter.  Name of the module for indexing Microsoft office files is "Microsoft Office.mdimporter" and it can be found with a few other modules of .mdimporter in/library/Spotlight /.  The "Microsoft Office.mdimporter" module has rights author of Microsoft inside its packaging info so we know who wrote it.  But this module is included with all new Macs from Apple.  This is perhaps why this problem has never been corrected - the software is written by Microsoft, but delivered by Apple.

    The symptoms of the problem are that Spotlight will find no content in some .docx files.  It is unclear why it fails on some .docx files, but not others.  This problem does not affect other Microsoft formats such as .doc, .xls, .xlsx, etc..

    Because Apple wants to sell Macs to business, and companies make heavy use of MS Office in general, we could think that it would be a priority to fix.  But given that this problem is 7 years old and still not resolved I do not.

    Any suggestions on possible alternatives would be welcome.

    After further investigation, I discovered that the problem is not with "Microsoft Office.mdimporter" as I had thought.  If we run the mdimport(1)-d1 you can see what importer is used. It turns out that for the .docx files, the importer is called 'RichText.mdimporter' which has a copyright by Apple.  And if you use mdimport(1), the file will then be found by Spotlight.  If the issue is not the importer, but rather everything that is triggering the importer to run the .docx files updated.  Here's to blame Microsoft for this one...

    As a workaround, I force indexing my files .docx with a Bash script, which is started by cron.  The script indexes all the .docx that have been modified in the last 24 hours and runs every hour via cron.  If someone is interested in the details just post here and I'll include the script in another post.

  • Backup has encountered a problem during backup of the C:\windows\system32\config\systemprofile\Desktop\music file. Error: (System does not find the specified path. (0 x 80070003))

    I had to uninstall iTunes a few months ago and successfully re-installed, but part of my music was missing.   At one point, following the instructions on a thread on the forums Apple or Microsoft, I saved my music library on the desktop. Since then, I do not have a library of music on the desktop file.  In my looooooong hours trying to fix things, I do not know if I deleted it or what.

    Now, I get the message:

    Hi serene,

    Thanks for posting your query on the Microsoft Community.

    As indicated by the error, this problem appears, when these files/libraries that are saved automatically are not present on your computer. I suggest you to follow the steps below and check, if it can help solve the problem.

    • Create missing files that are listed in the error message.
    • Exclude files from the files to backup in the backup settings and then include these files in their original location. To exclude folders in other communities and to include these files in the original location, follow these steps:
      1. In Control Panel, open backup and restore.
      2. In the section back up , click change settings.
      3. In the dialog box Configure the backup , click Next.
      4. In the dialog box that you want to save , click Let me choose, and then click Next.
      5. Expand data files, library, expand additional locations, and then click to clear the check boxes folder AppData, Contactsand Research .
      6. Expand computers, expand the element of your system drive (for example, expand Local disk (c)), expand users, , and then click to select the checkboxes AppData, Contactsand Research if they exist.
      7. Click Next, and then click Save settings and exit.
      8. Backup and restore, click back up now to perform a new backup. The backup operation must complete without errors.

    If the problem persists, I suggest you follow the steps in the following article for troubleshooting backup problems.

    Hello

    You did changes to the computer before the show?

    These problems occur because the folders or libraries that you are trying to back up or restore include a reparse point. Analytical points are similar to shortcuts Windows or Unix symbolic links. A point of analysis can be used to point to a file that is moved temporarily to a different drive.

  • backup rman design database with phsical ensures

    Hello

    12 c database, after physical expectation is created, I need backup rman configuration,

    The goal is: a) backup of database b) remove archivelogs that have been backed up, free up space FRA.

    Design as below:

    1:

    in RMAN (primary and standby):
    RMAN >
    Configure controlfile autobackup on;
    set the type of backup device type disk compressed backupset;
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;


    2: primary school:
    RMAN > CONFIGURE RETENTION POLICY to the 5 DAY RECOVERY WINDOW;

    3: in priamry, turn on track changes to block

    4: primary, implemented since rman level 0 (full backup) on Sunday.

    5: in the primary, the installation program rman level 1 backup from Monday to Saturday.

    6: primary, set up since rman "save archive backup delete them all obsolete" every hour;

    questions here:

    1. as in step 5, for the protection of the o and delete archivelog, the script using:

    Run {}
    allocate channel d1 type disk;
    SQL 'alter system archive log current';
    overlap archivelog all;
    backup AS COMPRESSED BACKUPSET archivelog all delete them all input;
    output channel d1;
    }

    I wonder if ' archivelog all delete all entries "will delete archivelog which was not taken on the eve of the database and broken standby database

    (hanging and out-of-sync with primary)... it is a concern, is that possible?

    2. If the primary database crashed, failover to standby mode, then restore/recovery primary, switch back to the primary, this design is just? If you have any good suggestions, please let me know.

    (to put it simply, I don't want to full/incremental backup to install standby, primary server CPU is good enough)

    Thank you very much!
