Restore cold backup

Hi
After restoring the cold backup
I need to recreate the controlfile.
Do I need to recover afterwards? since I created new controlfile.
or just
alter database open;

Oracle 9i, user managed backupsWe have said couple of things many times but seems that people don't really care.
1) Always mention complete thing/story, not just a snippet of it.
2) Always tell the complete version, 9202 9208.
3) Check the oracle docs,

  • Restore cold backup without resetlogs option

    Hi,
    im using oracle 10.2.0 , i'm migrating database to SAN, how can i restore cold backup with noresetlogs.

    Hi pawan,
    steps i will follow are as follows:
    1. take backup of controlfile with noresetlogs.
    SQL> database backup controlfile to trace noresetlogs;
    2. Shut down the database, take cold backup(datafiles,redologfiles).
    3. recreate the controlfile.
    4. the open the database with noresetlogs
    are the steps fine or need any changes.

  • How to restore cold backup + archived log files

    Hi,
    Suppose I take a cold backup on 18th. After that I have four days of archived log files. if the database crashes on 5th day, I have to restore the 18th cold back + 4 days of archived log files. How do I restore since it is a cold backup and I cant do incomplete recovery.
    can I use
    Recover database ( with 18th cold backup) in mount state and apply archived logs.
    Prabhath

    The details of how you perform forward recovery using a cold backup depends on
    1- rman or manual backup
    2- using current or backup control file
    3- if rman, recovery catalog or no recovery catalog
    4- if full database recovered or only a few files
    Each of these conditions will affect what is known to Oracle and what needs to be done. For example if you restored the entire cold backup including the control file then Oracle would see a consistent database and not need to perform recovery so you would need to startup mount and tell the database to perform recovery using a backup control file. If using rman and no recovery catalog you might need to catalog some of the archived redo logs, etc....
    It is advisable to consult the Backup and Recovery manuals before attempting recovery for any new scenario.

  • ORA-12560 in database restore cold backup

    Hi guys,
    I'm trying to restore a cold backup (WINDOWS NT) and I did the following:
    1. Restore the datafiles in a specific location, according to the directory that the files were before.
    2. Create the service:
    C:\>oradim -new -sid ORCL -startmode auto -pfile C:\oracle\admin\ORCL\pfile\initORCL.ora
    3. startup the listener with the instance.
    4. When I try to connect as follows, I receive the following error:

  • Restore cold backup and RMAN backup

    Hi,
    I have cold backup as well as RMAN backup. But i don't know how to restore the backup.
    Please anybody send, steps or links for restoring both backups.
    Regs,
    Brijesh

    The "script" would depend on how the backup was done.
    A cold backup should be a backup of controlfiles and datafiles.
    Was it done using RMAN ? Or done using an OS command (e.g. "cp" or "tar" or "cpio") ?
    A non-RMAN cold backup can be restored with the same command that was used to create the backup. If the backup did not include the Online Redo Log files, you need to simulate a dummy recovery from the SQL command line (RECOVER DATABASE UNTIL CANCEL ; then CANCEL) and ALTER DATABASE OPEN RESETLOGS.
    If the backup was done using RMAN, you need to
    1. RESTORE CONTROLFILE FROM '/location_of_backuppiece'
    2. ALTER DATABASE MOUNT
    3. RESTORE DATABASE
    4. ALTER DATABASE OPEN

  • Partition Restore Cold Backup Different System and Different Version DB

    Is it possible, can we restore the cold backup at different database version and different operating system(but same ENDIAN_FORMAT) ????????
    My original system HP-UX (64-bit) and database version 10.2.0.3.0 i have cold backup and i want to partion restore on Linux Redhot 5.5 (64-bit), database version 10.1.0.4.0 .
    If it is possible. How can i do this.

    My original system HP-UX (64-bit) and database version 10.2.0.3.0 i have cold backup and i want to partion restore on Linux Redhot 5.5 (64-bit), database version 10.1.0.4.0 .1. AFAIK you can not do it i mean wiht cold backup move from HP to linux

  • How to restore cold backups on other server

    Hi all
    On Oracle9i production server, we have windows scheduled job to take the cold backups every day night. The size of the database is 2GB.
    Now, the cold backup consists of
    - Database files & Log files
    - Parameter file
    - Control file.
    I am required to check the validity of the cold backup we have. So, I need to restore the database in another server.
    So, please provide me the steps I need to do to restore the database.

  • Restore Cold Backup Into Test Database

    Hi all.
    Here's what I want to do...
    Copy TESTDB1 into TESTDB2 just by moving the datafiles across the network.
    Which files will I need to move over, etc? (control files and datafiles good enough?)
    Any input is appreciated.
    Thanks.

    I hope I'm not missing anything:
    spfile/pfile
    pwd file
    control files
    data files
    redo log files
    Some of them can be recreated but why bother if you can copy the full DB when is down. I'm assuming you have the same directory structure.

  • Restoring archive log after cold backup

    Hello forums users,
    I read many thing on this topic but I didn't find the good answer.
    I performed a cold backup each sunday.
    My database is in ARCHIVE LOG mode.
    Is it possible to restore ARCHIVE LOG files after restoring COLD backup?
    Sunday : cold backup
    Monday : new archive log have been created since cold backup
    Tuesday : same as Monday
    Wednesday : I would like to restore to Monday 22:00 for example
    Can I restore cold backup + apply archive log until Monday 22:00 ?
    Regards,
    Guillaume

    recover database using backup controlfile until cancel|time|logseq|scn
    will do this and prompt you for the archivelogs.

    I wish to perform cold backup using RMAN for the same i want to know following :
    1. What is the script / command ?
    2. How to restore cold backup completely ( ex:- if i lost all my data,redo and archives )
    3. Is it mandatory to open the database in RESETLOG mode after recovery ( since i have a cold backup ) ?

    A "Cold" Backup is called a "Consistent" Backup.
    See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297

  • ORA-00313: open failed for members during restore from COLD backup

    Hi all,
    I took a cold backup of an 11.1 database using RMAN (database in mount state).
    I used the following command to restore it:
    restored the controlfile and then
    RESTORE DATABASE FROM TAG 'TAGxxxxxxxxxx';
    Now I'm restoring it and it's taking too much time. When checking alert log it says:
    ORA-51106: check failed to complete due to an error. See error below

  • Restore from cold backup (rac server)

    Hi All,
    Oracle version : 10g
    OS : SunOS dixie1 5.10 Generic_118855-36 i86pc i386 i86pc
    I am having cold backup of RAC server (2 nodes), I want to restore from cold backup.
    The problem is that : when i performed the cold backup using rman at that time Oracle was having 3 ASM diskgroups.But unforunately that disk is no more in use due to some fault.
    Now my question is how can i restore from the cold backup as when i'll restore from the cold backup this will ask for the same ASM diskgroups.Even more if i creates the same diskgroup with the same name and same configuration then my doubt is that rman will allow me to restore the same from the cold backup as ASM disk header changed now ?
    Thanks,

    Yes.You can do these and restore/recover your database.First you need startup your ASM instance then create your ASM disk groups and do following:
    1.Edit pfile and change controlfile location to diskgroup(Consder that +dgr1)
    2.Restore controlfile to this disk group using backup of controlfiles(you say that is cold backup)
    rman target /
    /*Instance  need starting up from pfile*/
    startup nomount ;
    /*then restore controlfile,give full path of controlfile from coldbackup*/
    restore controlfile from 'coldbackup_location\coltrolfile';
    alter database mount;
    catalog start with 'coldbackup_location';
    backup as copy database format  '+dgr1';
    switch database to copy;
    alter database open;

  • Problem with restoring a database from cold backup

    All,
    I've got a 10.2.0.4 database that we perform a cold backup on every night with RMAN. On Sunday 2/21, we have level 0 backup. On Monday-Wednesday nights, we take a cold level 1. We also perform a controlfile auto backup each night.
    On a second server where I want to restore the database (same version of Oracle 10.2.0.4), I've copied the control file auto backups, the level 0 and the most recent level 1. I now want to restore. I use an RMAN script similar to the following to restore the control files:
    connect target /;
    set dbid 1973354860;
    # Restore the controlfile from the tag that auto backed up the controlfile at the end of the level 0
    run
    startup nomount;
    allocate channel c1 type disk;
    restore controlfile to '/u01/app/oracle/oradata/ORADB1/control01.ctl' from AUTOBACKUP;
    restore controlfile to '/u02/app/oracle/oradata/ORADB1/control02.ctl' from AUTOBACKUP;
    restore controlfile to '/u03/app/oracle/oradata/ORADB1/control03.ctl' from AUTOBACKUP;
    release channel c1;
    shutdown immediate;
    After the control files restore successfully, I perform some RMAN checks to ensure that all of the files I need for a recovery are there. The RMAN> list backup of database; command shows all of my backup savesets as AVAILABLE for the level0 and level1 backups.
    I then try a restore database command; and get the following errors:
    RMAN> run
    2> {
    3> allocate channel c1 type disk;
    4> allocate channel c2 type disk;

    So I'm unclear as to why RMAN believes the backups of these files don't exist when I attempt to restore the database. Anyone have a clue?
    NOTE: I've also tried to restore spcifically with the tag= clause but I get the same results:
    RMAN> restore database from tag='TAG20100221T200045';

    Just as a follow on to my last post, after the RMAN-06023 messages, I list backups of the three datafiles and as you can see RMAN thinks that they are available. If I exit RMAN and list them at the OS level, they are where RMAN things they should be:

    Please do not confuse between the backup copies you have. Ensure that you have the latest copy whether cold or hot. If you have COLD copy then simply replace all the data files, redo log files, and the control files and start the database it should start. I do not understand your back up strategy because if you have a Hot backup then why do you need a cold backup. Please let me know in what mode your database is running?
