Configuration of RMAN and REDUNDANCY

Hello
in 10g R2,.
with the configuration of RMAN follwing:
CONFIGURE RETENTION POLICY TO REDUNDANCY 8;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
How many backup files (before when, date on which) RMAN will remove physically from the disk?

Thank you.

'CONFIGURE RETENTION POLICY to REDUNDANCY 8;' means, RMAN will keep 8 independent backups of any window of time. Use 'CONFIGURE RETENTION POLICY to RECOVERY WINDOW of N days;', if you want to have a time-based retention policy.

  • RMAN and 05500: the auxiliary database must not be mounted when using DUPLICATE

    Hello

    Oracle10g2
    RHEL4

    The artist DR configuration using RMAN backup.

    There are two db Server computers:

    1) mac1-> backend
    2) mac2-> backup server

    File structure of database as a backup on the server location is the same.

    Entry TNSNAME on both servers are perfect, verified using tnsping.


    Now, to create a backup database.

    I made the RMAN backup on mac1 (main server) then transferred backup (full backup directory) to mac2 (backup server)

    Then, on the standby server,

    -> took on the eve of the database in nomount mode
    --> connected to the target database (i.e. standby db) with RMAN
    -> database connected to auxiliary

    But the granting of "Duplicate" command results in the error, as shown below:

    RMAN > target database double standby nofilenamecheck dorecover;

    RMAN-05502: the target database must be mounted on the issue of a duplicate order

    and when I put the target database (standby db) in the editing mode, gives the error below:

    where I did mistake? How to solve this problem?

    There is nothing wrong

    target (in fact the Pb of the source) must be mounted
    auxiliary (actually the destination db) can not be mounted.

    These messages refers to the source and destination db. from 11 g, you can duplicate opensource db (a.k.a. target)

  • silent install Firefox 27.1 and configuration (homepage, proxies and bookmark)

    Hello
    I am trying to perform a silent installation and configuration for 27.1 Firefox but I'm not able to get the same results I got with the 26 versions and below. For these versions, I used the method described in this link:
    http://www.mockbox.NET/ConfigMgr-SCCM/174-install-and-configure-Firefox-silently
    But for Firefox 27 creating the Mozilla.cfg and other files doesn't seem to work. Could you please tell me how silently configure the proxies and the homepage on Firefox 27.1 during installation. I also need to add a bookmark while installing. Could you please tell me how to do the same? I found a few methods saying that I had to change a bookmark.html file, but I don't think that this file is present on firefox 26 on.
    Thank you in advance.
    Kind regards.

  • I format the machine. How to back up the configuration of Firefox and bookmarks for re-installing later?

    I need to reinstall my operating system to windows 7. Firefox works fine. All I need is a procedure to save the configuration of Firefox and bookmarks to facilitate the configuration process when I re - install Firefox later. Thank you

    Firefox stores all your information in a folder called "account profile". If you back up to the top (on a USB key, for example), you can copy it back later after you have reinstalled your computer (including Firefox, of course) and all your settings, passwords, bookmarks, etc. will be present again. Take a look at: back up and restore the information contained in the profiles of Firefox.

  • At the start, my phone freezes on the configuration of updates and restarts

    At startup, my phone freezes on the configuration of updates and restarts. It won't let me even put my password. Automatically, it restarts and continues to do the same thing over and over again... I need help!

    What were the results of the test of the hard drive?

    It seems that things go too far and you need to perform a factory restore and reinstall the files on your system.

    Repeatedly press the F11 key at startup to enter the Recovery Manager, and then follow the instructions.  I hope that the recovery partition is not damaged.

  • the API system configuration error 1097 and freezes

    I used successfully the API system configuration to detect and read information on a PXI chassis.

    But now, when I try to initialize and collated all information using a simple VI, the system returns error 1097 and crashes before the end of the VI.  Based on that the stop button does not work and I have to either soft or hard reboot the machine.

    I have attached a screenshot of it in a frozen state and error, like a report of what is installed on my system.

    The only thing I can think has changed since this last worked has been upgraded my MAX and other pilots from 5.5 to 14.0 and then the latest version as of today.

    It is usually the generic error, which means that some external code access violated the integrity of the system and the memory is likely to have been corrupted in the process. Since it is a NI API system AND it seems to have worked before, I guess it's not a bad disigned call library node, but a form of bribery in external code library itself which implements the API of the System Configuration.

    Reinstalling may solve the problem.

  • How can I put the Windows XP firewall in a port configuration 'allow all' and only block some ports?

    Without going into the details of why I need to do this, I'm putting the firewall of Windows XP in one allow all the configuration of ports and only refuse some ports I have in a list.

    I train this script via the command-line batch with the netsh firewall add portopening command.  From what I've read, if enabled the firewall denies all traffic and only allows ports with exceptions, so through batch scripts, I opened all the 65 000 + ports TCP and UDP, essentially with the firewall turned on but in a configuration of "allow all the»  I don't deny the 100 or so ports to my list that I want blocked after they are all open.

    This strategy seems to work, but the problem I waited and I now see is that svchost.exe takes 50% of my CPU time, have to deal with constantly these firewall rules.

    "From what I've seen on Windows XP, there is no way to have the firewall ON, and in a configuration of" allow all the "" because the XP firewall may not have defined port ranges, they must be defined one by one.  It looks like Windows Vista or 7 would be much easier because the firewall has got a re vamp of advanced features.

    Does anyone have a suggestion on how to realize this "allow all", deny some' strategy?  I know it's a strange use of the Windows Firewall, so let's please jump in front of a 'why would you do this incredibly stupid thing?"messages.

    Also, if it was the wrong forum (or website) to post on for this kind of question, I'd appreciate a recommendation of a more appropriate forum.

    Make sure you write down the description and model double click top - tab drivers - write version. Now
    Click on update drivers who cannot do anything like MS is far behind the certification of drivers. Then RIGHT
    CLICK above and UNINSTALL - REBOOT - this will rebuild the driver stack.

    If your driver shows 06 you have the default windows and part of the question.

    Go to the system manufacturer's website and get the latest Audio/Sound drivers - download - SAVE - go to the place where you
    Put them - right click on Reboot - RUN AS ADMIN -.

    Check the Version on the tab of the driver in the device as a sound Manager often restoring drivers, then install
    the current version. Restart and check after each try, not uncommon to have to run the pilot of 1 to 4 times or more.
    Just make sure that the version you have installed appears in the tab of the driver.

    Then navigate to the site of the manufacturer of the device and search for the drivers more recent and repeat the installation procedure.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    Hello

    I have 12 blackberry 9720.

    They have been somehow configured to work as a business smartphone.

    Now the company wants to reject the old Blackberry Service Administrator.

    I can't set up any kind of e-mail on these phones.

    After several resets factory they continue to ask for a business email account.

    Is it possible to set up a simple gmail account on them?

    Better yet, is it possible to manually set the old account? (I can do this on a samsung or on an iphone).

    Whenever I try to configure one of them that I make you to configuration-> email account-> and I can only activate a company account.

    I want to just configure emails.

    Hello

    Assuming that you have:

    • The devices removed from BES/DOWN
    • Passed under the carrier on each device BES to BIS account

    Then the devices should have ' Personal/Internet' showing on the screen. Note that the company will always show up on this screen, no matter what. But it is only useful for devices in a BES environment. For non - BES, you need a plan BIS of data by the carrier in order to activate the exclusive services of BB (which includes the e-mail handling on these devices inherited from BBOS). And, if the data carrier account does not exist OR if it does not BIS, then the screen will show exactly as you describe, and email does not work on the device.

    Good luck!
