Recover db without backup sets rman

Hi,
Is there any way to restore the database without backup sets. We have the recent incremental backup, however the backupsets have failed.
Please advise.

RMAN backupsets are defined to have a retention period and moving the backup from disk to tape and then freeing the space on the disk.
where did you get this definition?
RMAN can store backup data in a logical structure called a backup set, which is the smallest unit of an RMAN backup. A backup set contains the data from one or more datafiles, archived redo logs, or control files or server parameter file. Backup sets, which are only created and accessed through RMAN, are the only form in which RMAN can write backups to media managers such as tape drives and tape libraries.
A backup set contains one or more binary files in an RMAN-specific format. This file is known as a backup piece. A backup set can contain multiple datafiles. For example, you can back up ten datafiles into a single backup set consisting of a single backup piece. In this case, RMAN creates one backup piece as output. The backup set contains only this backup piece.

You will need to define your problem in detail if you know what the problem is. what are you trying to achieve?

  • Recover Database without backup

    Hi Joel,
    I have read most of your postings regarding database recovery, but still encounter problems.
    The background is: Our NT server was crashed last weekend, due to harddisk failure. We are able to retrieve back all the datafile, control file, everything in tact. But after recovery, the OS fails to recognize the ORacle and require reinstallation. We don't know how to re-associate this new instance of Oracle with the old databases that we have created.
    I did create a new DB in the new instance, copy back the datafiles, control files to replace it, and run the recreate control file command that you have suggested. At the very final step, when doing recovery, it shows this message:
    SQL> alter database open;
    alter database open
    ERROR at line 1:

    if the datafile does not contains tables that are needed for some application , or not belong to system,sysaux tablespace , offline datafile can be some solution.
    To recover a datafile without backup you need alll the archives from the date that the datafile is created.
    Please make a procedure for backup
    A sample backup script can be founded http://mikegeorgiou.blogspot.com/2007/04/user-manage-backup-9i.html

  • Recover datafile without backup

    9.2.0.4 archive log mode
    I delete the data file for statspack, and I use cp do hot backup every day but I did not do backup for statspack tablespace, now i want restore the datafile,how can i do?(i try use alter database create datafile as, but faild with ora-1516).
    thanks.

    Well, you can't really have it both ways!
    Either the file exists and needs recovery, or it doesn't, in which case referencing it will get you an ORA-01516 error.
    You said you deleted the file (from the disk, presumably?). That would not have removed a reference to that file from the control file. Only a 'drop tablespace' command would have done that. Did you "delete the file" by issuing that command?
    Because if you did, you can't recover the file, period.
    The technique that others have mentioned (of re-creating a 'blank' file and applying all redo to it since the time of its original creation) only works if the control file is already aware of the nature and characteristics of the original file. If you did a 'drop' command to remove the original, you've wiped the control file's awareness of the files attributes and properties and, short of restoring a backup you don't possess, you're stuffed, I'm afraid.

  • Restore from Time Capsule backup set

    What is the procedure to recover the other paritions (multiple) which are backed up using time machine?
    I am using Time capsule to maintain automated backups of my Macbook Pro. Backups to the Time capsule are performing correctly and I can see "pink" breakpoints when I enter time machine which means the backup sets are available on my time capsule. I have 3 partitions on my MBP hard drive and all these drives are included in backups to be done.
    When I tried to recover my entire backup set to a new machine I was able to restore all the contents of my boot drive (mac os partition) but the data on other partitions is not recovered. I tried multiple times with different options to recover my data on other partitions but no success. What is the procedure to recover the other paritions which are backed up using time machine? Please refer the attachment to understand my partitions which are backed up but not restored?
    I really need help on this matter as I need to streamline restore process in my organization using time capsule.
    Thanks in advance.

  • Backup set in the tape. copied into disk. how to recover using RMAN

    I have backup set in the tape. copied into disk. how to recover using RMAN
    any link and steps please

    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
    connect target /
    restore database
    4. recover the database
    rman
    connect target /

  • Duplicate an old RMAN backup set on Oracle 9.2.0.8 with no catalog

    Version: 9.2.0.8. We don't use an RMAN catalog

    I presume this is happening because the target database has a retention of one day and is unaware of this rman backup that is about 20 days old.
    If this is true, is there a way of telling the target database about this old backup set that I now want to duplicate?
    From 10g onwards you can catalog a backup piece which might be the fix for this??
    I've got round the problem by restoring the database to a different server, but would still like to know if the above is possible.
    Can anyone offer any suggestions? thanks.

    Hi C3PO,
    I presume this is happening because the target database has a retention of one day and is unaware of this rman backup that is about 20 days old?Correct the backupset metadata is nolonger available.

  • Recover database after lossing system tablespace without backup

    Hi
    My database fail because of hardware failure and then system tablespace corrupted. other tablespaces and control files are OK. Can I recover my database without backup of system tablespace?

    hi,
    if you have not taken the physical backup (inconsistent or consistent) then you can not recocver it. you need to have some backup up strategy with RMAN or Manual. Do you have hardware (Disk) Mirroring to cover the media failure??
    Atleast if you have the logical backups?? then create the database and import it..

  • RMAN backup set path

    I am restoring the production database to testing server. i have taken the cold backup of my catalog database and refreshed on development server so that i can have information about the production db in RMAN catalog db.
    i have copied the backup sets ( level 0 ) of my production db to development server. backup set path is not identical as production. so When i try to recover in dev server i am getting error file not found. ( not able to find the backup piece ) since it is point to production backup set path.
    how do i set or update the RMAN database about my testing server backup set path so that during the recovery rman reads from new location on the development.

    thank you.
    I am facing problem while restoring the database.
    i trying to restore from level 0 backup which we take daily basis. when i use the below command and while restoring one of the datafile referring the old backup set which is not available. i have valid backup sets taken yesterday. but rman refers the backup sets taken on day before yesterday.
    i am using the following command.

    As a side observation, you need to follow those 'crosscheck' commands with 'delete noprompt expired....' commands
    The only thing the 'crosscheck' does is mark the record of the copy|backup|archivelog (in the repository) as 'expired' if the copy|backup|archivelog itself is found to have gone missing.  The 'delete ... expired' command then deletes the records that have been marked as 'expired'.

  • Extracting Backups Sets from ASM with RMAN (10g)

    If I backup my database to my flash recovery area in ASM using RMAN, can I then extract those backup sets from ASM and turn them into normal file system files?
    I think I read that you can do this but I just wanted to be sure. I don't need super detail on this, just get me pointed in the right direction.
    I've certainly read about extracting a database from ASM, but I'm just not sure how I'd migrate an individual, arbitrary file.

    http://www.oracle.com/technology/oramag/oracle/04-nov/o64rman.html#T2 describes something like this, in the "Adding ASM" section. Here's the excerpt:
    Files inside an ASM location are not accessible as operating system files. To get the backups and archived logs from the ASM disk group to regular disks and tapes, John will use RMAN to back up the recovery area from ASM to tape (at the network backup server) through the following command:
    BACKUP RECOVERY AREA;
    This backs up the entire recovery area, including data file backups, archived logs, and control file backups from the ASM disk group to the tape.
    So, this would lead us to believe that what we want can be done. However, I read somewhere in the RMAN doc that BACKUP RECOVERY AREA will only create a backup to an sbt (i.e. tape) device. That is, it would appear that RMAN cannot store backups in ASM, and also allow you to "export" them to disk. You can export to tape, but not to disk.
    This is disconcerting. I'd like to store all Oracle-related files under ASM, but I'd also like to allow our tape backup procedures (which I am not in control of, and which do more than just backup Oracle) to easily just grab OS files that I put out there.

  • Update from 3.1.3 to 4.x CORRUPTED WITHOUT BACKUP! How to recover data

    My screen stays in recovery mode. Cannot switch to normal boot mode.
    I cannot restore from iTune, since I need the photo data in my phone.
    Anybody know how do I recover the data?
    Thanks!

    I am not sure what will happen if I click restore now.
    Most likely, you will lose everything. Data, photos, installed apps (they still are in iTunes, btw), etc.
    Unless you had flagged to sync your photos on iTunes: you can found them (at least, the last synced ones) in the folder you told to store photo data.
    If you using a Mac, check your iPhoto app, or Pictures folder. If windows, check your Images folder, to see if they were in. Good luck!
