RMAN backupsets to disk - how to parallelize?

Is there any way to utilize Oracle RMAN backup parallel features via BR*Tools when performing backup to disk?
Platform: Windows if it is relevant, Oracle 10.2.0.4.
The only way I found so far is to use exec_parallel parameter in BRTools profile and in this case parallelizing done via starting n processes of RMAN in parallel when each makes backup of separate datafile. The aim is to do something with BRTools parameters to get parallel option 'inside' RMAN (equivalent of "RMAN> CONFIGURE DEVICE TYPE disk PARALLELISM n;").
The other part - how to parallelize offline redo log backups for RMAN backupsets? Even having exec_parallel parameter set to >1 only one process of BRARCHIVE is processing all offline redo logs serially.
BR*Tools parameters which I changed from baseline:
backup_mode = full
backup_type = online
backup_dev_type = disk
archive_function = save_delete
disk_copy_cmd = rman_set
rman_compress = yes
rman_cross_check = arch_force
exec_parallel = 4

Hi Vladimir,
>> Well, BRARCHIVE does support rman backupsets; not directly through command line parameters but via parameter file.
You need to use external backup library in order to use backupset by BRARCHIVE with the parameter "rman_filesperset" in init<DBSID>.sap. Please check the link;

>> Is there a way to create disk RMAN backup via External Backup Library?
Are you asking this for BRBACKUP or BRARCHIVE? First of all, you can the note "1101530 - Support for RMAN savesets for backups on hard disk"
And the the links, below;
Profile Parameters and BRBACKUP Command Options->

    It should be something like the following, but really you should read and understand the rman documentation first ...
    1. restore the controlfile
    sqlplus / as sysdba
    startup nomount
    exit
    rman
    connect target /
    restore controlfile from '/path to the controlfile backup piece';
    exit

    alter database mount
    exit
    2. catalog the backup pieces
    rman
    connect target /
    catalog start with '/path to backup pieces';
    3. restore the database
    rman

  • FIles of same RMAN backupset

    Hello all gurus,
    Sir,
    Version : ORACLE 9.2.0.1.0
    O/S : Windows XP
    I wish to know how can I check which physical files are of same RMAN backupset.
    Thanks in Advance

    You can do two things.
    Issue from the RMAN prompt, list backup;
    This will give you the listing of the backupsets and pieces. Check over there in the media that actually those pieces are there or not?
    Or you can issue list backup and then issue crosscheck backup.This would verify that the backups coming up in the listing are actually available over the physical hard disk or not?

  • ORA-01152 when restoring from RMAN backupset in NOARCHIVELOG mode

    Hi all,
    I got the error ORA-01152 when I tried restoring an Oracle 10g R1 database from an RMAN backupset into a new server. The error returned when it reached to the level of opening the database in resetlogs.

  • Can we rename/relocate the RMAN backupset?

    Hi All,
    Can we rename/relocate the RMAN backupset?
    I have the following scenerio:
    1.took tha backup on /u99 mountpoint using rman
    2.copy the entire backup to tape
    3.filesystem /u99 scrapped
    4.created new filesystem /u101
    5.copy the backup to /u101 from tape.
    Now we have to restore the database..but problem is that rman dont know /u101, by default it will search from /u99 filesystem...how to tell rman take the backup from /u101 not from /u99...
    Please help me
    Regards
    Symal

    You need to use the RMAN command
    SET NEWNAME FOR DATAFILE <datafile_number> TO ‘<path_and_filename>’;
    for each datafile you want to restore and recover.

  • What are the caveats of using ASM as storage for RMAN backupsets?

    Hello all,
    We are currently evaluating RAC as our standard database platform. Until now we have been using 10g single instance with ASM for datafiles and local filesystems for RMAN backupsets and archivelogs. We chose to use local fileystems for backup components so that we can utilize a Tivoli filesystem backup in order to secure the backup pieces to tape.
    With RAC, we are looking into a shared location for backupsets and archivelogs. OCFS2 is out of the picture due to it not functioning on top of linux LVM. It appears that our only "shared" option is to use ASM for backupsets and archivelogs.
    My concern is that while the data diskgroups and rman diskgroups will be separate, they are both running on ASM and therefore if ASM fails or is corrupted, we have nothing. My current plan is to utilize the Tivoli RMAN MML (TDPO) to backup the backupsets to tape after the ASM backupset has completed.
    What experiences have been had with using ASM for RMAN backups?
    Any advice on additional protection we can employ to ensure that the database remains recoverable?
    Thanks in advance,
    David

    I've personally haven't implemented RMAN with ASM, but you may want to review Faster Backup, Faster Recovery which discusses RMAN utilizing ASM.
    And although you may not get any of the negative aspects from these presentations, you may want to check out High Availability Customer Case Studies, Presentations, Profiles, Analyst Reports, and Press Releases.
    Hope this helps!

  • I lost my emac G4 installation disk, how can i get my admin password back?

    I lost my emac G4 installation disk, how can i get my admin password back?

    Here's one method to reset the password without the install disc:
    1. boot computer and hold the "apple" key and the "s" key.
    2. wait for terminal show
    3. release keys
    4. type without the quotes: "/sbin/mount -uaw"
    5. press enter
    6. type without the quotes: "rm /var/db/.applesetupdone
    7. press enter
    8. type without the quotes: "reboot"
    9. press enter
    This will let you create a new admin account when you reboot your computer.
    Also, without the discs, look at Mac OS X Tip - No Password, No Root, No CD? No Problem.
    http://www.macobserver.com/tip/2003/06/16.1.shtml
    Here is a way to get around not knowing the admin password on Macs.
    To reset your OS X password without an OS X CD you need to enter terminal and create a new admin account:
       1. Reboot
       2. Hold apple + s down after you hear the chime.
       3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
              * mount -uw /
              * rm /var/db/.AppleSetupDone
              * shutdown -h now
       4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!
     Cheers, Tom

  • Since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists

    since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists?

    My own opinion is that you should install the later appropriate version of Silverkeeper. That said, I would in fact recommend if you can wait a few days for an answer, that you email the La Cie Silverkeeper backup team via the email link on the site at http://www.lacie.com/silverkeeper/
    They are careful to say they are not officially providing a backup service, but when I emailed them with a query regarding usage about a year ago after downloading Silverkeeper for myself, I got a reply within a couple of days that cleared up my question.

    Well then when you erased your hard drive, your erased the Recovery partition, also.
    Use Internet Recovery to either restore from your Time Machine backup or reinstall the OS if you don't have a TM Backup.
    It will install the OS that shipped on that Mac. You can then upgrade via the App Store.

    Firstly, what is the source of the 10.6.4 disc? Is it the original installation disc for your MacBook, or one 'borrowed' from another computer?
    It isn't the retail version, because that's 10.6.3.
    Assuming it's the correct disc (i.e. the one that shipped with your Mac), you need to boot from it again.
    OK the language page.
    From the installer screen, ignore the continue button, go to the menu bar and choose Disk Utility from the Utilities menu.
    In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.).
    Run Repair Disk. If that comes up as disk OK, click the partition tab. Select the partiton from the drop-down above the graphic; 1 partiton is all you need.
    Go to the options button and ensure that the partition scheme is GUID and the file system to Mac OS Extended (Journalled). Name the partiton (usually Macintosh HD), click Apply.
    When the Macintosh HD volume appears below the drive name, quit DU and see if you can then install.
    If the screen after the language screen doesn't show the menu bar, it may be necessary to use another Mac to do the job with the MB in Firewire Target Disc Mode. If it won't boot in TDM, or the MB doesn't have FireWire then it's getting very difficult.

  • Since SSD is now my 1st disk, how to have 2nd HDD off on startup by default?

    Hello,
    Since SSD is now my 1st disk, how to have my 2nd HDD (in the DVD bay / caddy) OFF on computer startup ?
    (This will prevent the HDD to be in rotation : it is not needed. I don't use it until a want to access some files which are on this HDD).

    Yeah, I want the OS to turn on the HDD, dump out the file, then immediately turn off the HDD. I also want the OS to cache all HDD directory and file information so that the HDD stays off, quietly, when I browse around the machine.
    Not going to happen.
    I can invest $500 (or about 385 euro) in a SSD.

    i lost my iphoto application how i can restore it? i am not having system restore disk. how i can get my photos back?

    If the iPhoto application is no longer on your hard drive (do a search to be sure it didn't just get moved to an unexpected place), there's no way to get it back without either backups or a copy of iPhoto.  Your original disks that shipped with the machine would have iPhoto.  If you have lost those disks and don't have backups, you'll simply have to buy a copy of iLife.  Or call Apple with your machine's serial number in-hand and request replacement disks, which they will send you for a small fee.

    There is a question mark on my hard drive disk, how do I get rid of it. I recently went to the genius bar in Albuquerque, NM and they restarted it and did a partition on it and what I needed was fixed but I still have a  question mark on my start up disk.

    There is no startup system on it. Or, you need to open Startup Disk preferences and select a startup disk. Or your startup disk lacks a name such as "Macintosh HD," for example.
