switch after the hot backup log file

Hello world
Why should we change log file after the end of the backup command that is to say, after the end of the backup hot?
Why we should take a backup control files to database level, but not through operating system level that is to say, order cp?

Why we should take a backup control files to database level, but not through operating system level that is to say, order cp?

If you're doing a cold backup, this is where you use cp.

But when the database is in place, controlfile is used and it is continuing to change the oracle process. Now the question is how to get the consistent image of the controlfile, here's where you their support at the database level (for example backup controlfile). When you do that level database, a snapshot file is created time and she is saved.

  • Where is the official Oracle documentation that describes the hot backup?

    I used the cruelly utility failure to search for Metalink and Google, but the closest thing, I found is a description on "ask Tom".

    I'm looking for official Oracle documentation that describes what is happening internally during a hot backup. There are many websites and blogs out there that describe, but I'm looking for a description of Oracle themselves. The only things I found in the Oracle documentation until now is to know how to start and stop the hot backup, but not what is happening internally. GR 11, 2 preference if it made a difference.

    Thanks in advance.

    Hello;

    Its probably gone RMAN covers this.

    The closest would be:

    Backup and recovery reference 11g Release 2 (11.2) E10643-06

    Or

    Backup and recovery User Guide 11 g Release 2 (11.2) E10642-05

    See Chapter 8 - Concepts of backup RMAN - online backups and backup Mode

  • excluding tablespace in the hot backup

    Hi master,

    I use oracle 10g on linux. We use the hot backup to date strategy to back up the database.


    but I think that I support too much data. I now have tablespeces in my database

    System
    users
    Temp
    Cancel
    index
    perfstat
    blob1
    tool
    etc. and default tablespace installed by oracle at installation time.

    I can I exclude some of the hot backup table spaces so that it consumes less time to back up the database?


    can I exclude spaces of temp, perstat and tool table?

    It will cause no impact on the database and?

    Thanks and greetings
    VD

    DON'T think to drop your UNDO tablespace. You use it to save "in front of your block images.

  • The hot backup process

    Hello

    I have a Dev on Oracle 10 g (10.2.0.3 on Solaris 8) db, for which I want to set up a simple backup process hot. My question is: for simplicity, instead of putting each tablespace in backup mode and to take it out of backup mode, can I put the entire db in backup mode and copy the data files and control and take the Pb of backup mode:

    -J' my intention to do so hours offline when activities are lower and db is small and there is enough space to make it so again is generated (compared to each tablespace in backup mode) that this is acceptable. Thus, the following process is valid:

    (1) connecting to the db as sys
    (2) alter database begin backup
    (3) copy all of the files and control the db for the backup
    (4) change the backup of the end
    - or after it is necessary to issue the - modify the statement of system switch logfile also? -If so, what is the purpose of this statement?

    Also another question is: I don't have enough space on the db server hosting backups so after you put the db in backup mode, I transfer the file in Microsoft windows server for solaris. -Is possible with rman?
    The reason why I go to managed user backup, of rman is that we do not store the backup on the db Server nor we have any tape, but we have a windows machine that can be used to store backups. so in this case, is it possible that rman can be used?

    Thank you very much
    Cedric

    When you use RMAN, you don't have to put a tablespace (or database) in BACKUP Mode.

    With RMAN, you can create of BACKUPSETs, in this case, backups can be smaller than the actual database files as RMAN does not save the blocks that have never been used (that is to say, the blocks above the last measure in a data file). In addition, you can create AS COMPRESS in order to introduce more compression.
    Alternatively, you can creat backup as Copy, in which case backups are the same size as the data files that you might have with scripted backups (UserManaged).

    You MUST run your database in ArchiveLog mode.
    You MUST save each ArchiveLog.
    You must save your controlfiles as backup controlfile separate. However, even if you do not configure CONTROLFILE AUTOBACKUP ON, whenever you back up the SYSTEM Tablespace (that I advice every day), the controlfile is going to get backed up in the same backup set. For added convenience, I prefer controlfiles backup as separate backups so that they save files are easily identifiable.

    I don't have a solution to your problem of "dvd".
    I have a suggestion:
    Forget to take the backup of files with dvds.
    Buy an external hard drive and use it for backups of files.

    A hard disk of 1 TB post can be had less than $100, to the Canada. The United States will be even less.

    Thanks to the external hard drive for backups of files, you don't have to sit by the computer and feed it with DVD whenever he asks. You can walk away. The computer will do its thing without you.

    A 2 x 4 in box will store all your files. No DVD more formatting. No more marking each dvd. No stacks more DVD.

  • stop the database when the HOT backup running

    Hello

    Can someone pls tell... WHT can impact on the database if the database will get stop accidentally during the hot running backup...

    Thank you

    There will be no impact on db; because its ORACLE database; very smart and easy to use.

    What happens if the instance goes down for the tablespaces into backup mode?

    When you start the database after that, Oracle will say that it requires recovery. It's because the RCS has been frozen and this is the expected behavior, because if you restore the file copied, it needs to be recovered. (and the only way that oracle has to set its value in the copy is put in the current file while it is copied)

    In this case, you can issue:

    ALTER DATABASE END BACKUP; ALTER DATABASE OPEN; to open the database.

    But your backup is not usable, it must do it again.

  • Redo log entries to the online redo log files

    Hello

    I'm a little confused about the redo log entries.

    I learned that LGWR writes redo log entries in the SGA, in redo log files in the following situation:

    -3 seconds after the last validation

    -redo log buffer has 1 MB

    -redo log buffer data 1/3

    When I take a transaction and if I change the wrong data, I have to cancel this transaction BUT the right now,

    What happens if the LGWR writes redo log disk entries?

    Is the bad transaction committed at all times?

    DML changes are "permanent" after that VALIDATION is issued.

    When any COMMIT is issued, then changes can be undone.

  • Commit complete, although the current recovery log file online have been removed.

    Even though I have deleted current online redo log file in the linux operating system (Linux of Oracle), when I hit 'commit' he says it committed "complete."

    It's just for this princip? *: "if only when all redo records associated with a given transaction are safely drive in online newspapers is the user process notified that the transaction has been posted." *

    I think that it can lead to data loss in some cases... I am using Oracle 11 g R2 on OEL (x 64)...

    Can someone explain to me? I'm stuck in this situation...

    PS: I don't have multiplexes current group ENT files...

    and these transactions are committed. It is in fact means that these transactions are not committed

    WHAT!
    In Oracle, if the transaction is committed - it is committed.

    I can't understand how the database allows users to validate transactions that are not actually written to the disc... is the concern of the operating system or the Oracle database?

    Your understanding is wrong.
    The newspaper is actually written to disk. This is the case. Even the name of the file is removed from the directory, the file is physically existing and can write. And all will be physically stored in the sectors of the disk HARD (or SSD).
    However, if the file is deleted, which means that his name is no longer in the directory, next time, Oracle will try to open it (by name) will fail because it will not conclude it in dir.
    This is why it is very important in this case do not stop at Oracle, but take the backup with RMAN and better to restore files deleted in OS using their inodes and the old names.

  • trap State of RMAN backup log file.

    Database: 10.2.0.2 enterprize edition
    Operating system: SUN solaris 5.10

    We will perform backups RMAN, level 0 weekend and incremental backups of level 2 and level 1 week. We will continually monitor the log through a HPOV tool file. This tool will send errors in the log file to the HPSMH ticket management tool.

    Now my concern is that we get several alerts every time that a channel failure and the canal failed is running with the other channel. Now, we want to check the overall backup status, if it is successful or not by checking the newspaper at a time.

    Please give me any suggestion to overcome this obstacle. We execute the RMAN backup with shell scripts and output will be appended to the log file.

    TIA

  • Can I recover the Vista backup specific file types?

    Ok. So I got a little happy relaxation of night last night and accidentally deleted all my music on iTunes, instead of just compensation for the library.

    Fortunately, I made a back-up week last using the Vista Backup Wizard, so I have nothing to lose forever.

    Question is, when I perform backup restore, can I just pick up music or will it also try and retrieve all my photos and documents too? I use Vista Home Premium 32 bit and backup to an external HARD disk.

    When you perform the recovery process, you can select what you want - it will give you this option as your use of the procedure.  I don't know if this can be done by file type (I doubt it), but it can be done by selecting the files and/or folders specifically.

    I hope this helps.

    Good luck!

    Hello

    I have a small business server, which is run through a network with thousands of files on as drawings etc.
    I have an employee who I suspect may copy files to our server for small businesses and keeping them to use in/when he left the company, then potentially to poach customers.
    I was wondering if there was anyway to get a log file which files are copied to the server just so I can make sure that this happens?
