Restoring a Hot backup using RMAN on a different server.

Hi
we are using oracle 10.2.0.4.0 on solaris 10 and using a separate catalog for RMAN backups.
we have taken a production db Hot backup as follows
level 0 backup on 28 th dec.
level 1 on 29,
level 1 on 30 and
level 1 on 31 st.
now today in the month of feb .
we would like to create a dev. DB on a diffent server which has diffent directory structure, i have to create a db using the above backups to setup the db like on 31 st Jan.
could you please provide the steps and advice how do i proceed.
Thansk fot the help.

Make level 0 and level 1 backups + control files backups + archived redo logs backup available on new host and use RMAN DUPLICATE.
See examples in http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/rcmdupdb.htm#i1008564

  • Restore hot backup using RMAN?

    Hi,
    We are taking hotbackup using rman level0,leve1,level2. Now i want to restore level 0 first then level 1 and level 2.. how to restore like this
    Thanks in advance

    You don't have to explicitly restore each L0, L1 etc backup.
    When you specify a SET UNTIL, RMAN identifies the backups (starting with the latest L0 before the SET UNTIL) that are to be restored and attempts to restore them.
    If the backups were to disk and are no longer on disk (i.e. you have moved them to tape), you have to ensure that the backups are made available (by copying them back from tape to disk).
    You can use RESTORE DATABASE VALIDATE and RESTORE ARCHIVELOG VALIDATE to identify the backups that are required.

  • Full Hot Backup using RMAN?

    Dear all,
    I want to take a full hot backup every week on sunday and the followings are the commands.
    run
    allocate channel ch1 type disk format '/db/BACKUP/RMAN/backup_%d_%t_%s_%p_%U.bck';
    backup
    incremental level 0
    database
    plus archivelog delete input;
    backup current controlfile;
    backup spfile;
    release channel ch1;
    I have the following questions:
    1) Am I need to define a directory named as "'/db/BACKUP/RMAN/backup_%d_%t_%s_%p_%U.bck", so that the backup copies will put it here,right?
    2) What format needs to be save in where and how to run it on weekly schedule basis?
    3) I saw above script with "channel ch1", can I change it to "channel ch2"?
    I am a beginner using RMAN, please let me know.
    Best Regards,
    amy

    Which database version on which OS (looks like Unix/Linux)?
    You have to create the directory '/db/BACKUP/RMAN', 'backup_%d...' is the filename created by RMAN.
    %d Specifies the name of the database;
    %t Specifies the backup set time stamp, which is a 4-byte value derived as the number of seconds elapsed since a fixed reference time. The combination of %s and %t can be used to form a unique name for the backup set;
    %s Specifies the backup set number. This number is a counter in the control file that is incremented for each backup set. The counter value starts at 1 and is unique for the lifetime of the control file. If you restore a backup control file, then duplicate values can result. Also, CREATE CONTROLFILE initializes the counter back to 1;
    %p Specifies the piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1 as each backup piece is created;
    %U Specifies a system-generated unique filename (default).
    For scheduling a cron job could be defined or you use Enterprise Manager (10g and higher)
    Channel name doesn't matter.

  • Frequency of Hot backups using RMAN

    Hello.
    After years of running various inhouse utilities to backup our Oracle databases we are now going to implement RMAN in our shop. We are running Oracle 10.2.0.4 EE databases on Solaris servers in Archivelog mode, so we'd like to perform "hot" backups. A caveat to this is that we also have "standby" databases that we manually manage via a series of scripts that works rather well and helps our CIO sleep at night.
    So what we're trying to do is tackle one obstacle at a time. We'd like to implement RMAN hot backups (including archivelogs) without having RMAN remove the archivelog backups that are out there. We simply want RMAN to backup the archivelog files, we'll manage their movement and removal ourselves for the time being.
    The script I have put together simply issues: Backup database plus archivelog format='/dumps/rman/F_Database_%d_set%s_%T_%U';
    The configuration settngs (we want at least a 2 day recovery period) are:
    RMAN configuration parameters are:
    CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
    CONFIGURE BACKUP OPTIMIZATION ON;
    CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
    CONFIGURE CONTROLFILE AUTOBACKUP ON;
    CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dumps/rman/controlfiles/%F';
    CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
    CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
    CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
    CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/dumps/rman/W_Database_%d_set%s_%T_%U';
    CONFIGURE MAXSETSIZE TO UNLIMITED; # default
    CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
    CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
    CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/xora01/app/oracle/product/10g/dbs/snapcf_glprd.f'; # default
    We are using an RMAN catalog.
    So my question is, if I perform the backup of the database (using the above command) once or twice a week and back-up only the archivelogs on a daily basis, would I be covered and save space at the same time? I think this might cover me as far as the archivelogs are concerned as well until my management is more comfortable with RMAN and allows us to install/use Data Guard.
    Thanks for you opinions/suggestions...

    Hi,

I think this might cover me as far as the archivelogs are concerned as well until my management is more comfortable with RMAN and allows us to install/use Data Guard.Your idea also not bad to save disk space. it is also depends on database size and space availability on your server.
    or else you can go for weekly once fulll backup, remaining days incremental backups & archivelog backups.
    rman incremental backups take only chanegd blocks so it wont occupy much space
    1) sunday - full backup - level 0
    2) monday - inc1 & arch
    3) tuesday - inc2 & arch
    4) wednesday - inc1 & arch
    5) thursday - inc2 & arch
    6) friday - inc1 & arch
    7) saturday - inc2 & arch... & so on...
    Thanks

  • How to restore RMAN hot backup to another database on another server?

    I want to know how to restore RMAN hot backup from production server to another database on a testing server.
    The hot backup is from a database named PROD on the production server
    The database to be restored with the hot backup is TEST on the testing server. There is already a PROD database on the testing server and this PROD database must be kept.
    I have read some threads about changing initTEST.ora to PROD to restore such backup but (I think) will not work in my case since I already have a PROD database on the testing server.
    The version is 11gR2 on Linux but the compatible parameter is set to 10.2.0.1.0.
    Thanks for any help.

    Hi,
    Since you are on 11g, hope this helps you http://shivanandarao.wordpress.com/2012/04/28/duplicating-database-without-connecting-to-target-database-or-catalog-database-in-oracle-11g/

  • Cold backup using RMAN

    Dear All,
    db_version :10.2.0.4
    os_version:Window 2003 server
    Environment:Test
    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 ) ?
    Thanks in advance

    A "Cold" Backup is called a "Consistent" Backup.
    See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297
    Backup :
    From the RMAN command line :
    SHUTDOWN IMMEDIATE
    STARTUP MOUNT
    BACKUP DATABASE
    BACKUP CURRENT CONTROLFILE  -- to get the controlfile in a separate backupsetRestore :
    STARTUP MOUNT
    RESTORE DATABASE
    ALTER DATABASE OPENIf you use an SPFILE, you can have an SPFILE backup included automatically with the controlfile backupset with CONFIGURE CONTROLFILE AUTOBACKUP ON and CONFIGURE CONTROLFILE AUTOBACKUP FORMAT ...

  • Restore the dropped tablespace using RMAN?

    Hello,
    I have done a oracle tablespace re-org for PSAPPOOLD,PSAPPOOLI. Now I want to restore only the OLD PSAPPOOLD,PSAPPOOLI tablespace using TAPE backup via RMAN. 
    The probelm is I have dropped the old tablespace during re-org which is a part of the re-org. Is it possible to restore the dropped tablespace using RMAN?
    My Oracle version is 9.2.05
    if anyone has done this before, please share your valuable ideas.
    I wrote the below script for the restore.
    run {
    allocate channel ch1 type sbt_tape;
    startup nomount
    restore controlfile; -
    >(I guess,if I restore old control file, I might get old structure which help the restore of TB)
    alter database mount ;
    restore tablespace PSAPPOOLD,PSAPPOOLI;
    recover tablespace PSAPPOOLD,PSAPPOOLI;;
    release channel ch1;
    Thanks,

    Hello Arjun,
    why would you want to do this?
    What is is you want to achieve by this action?
    BTW: it's not possible to do that.
    Check [Performing RMAN Tablespace Point-in-Time Recovery|http://download.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmtspit.htm].
    You want a "Tablespace point in time recovery" (TSPITR) for a dropped tablespace and that is just not possible with RMAN.
    So, the easiest way for you to get this tablespace back would be to restore and recover the database to a different host.
    Ah, while we're at it: using RMAN outside the BRTOOLS is not supported by SAP - so you better be a wiz with it because there won't be much help in case anything does not work.

  • PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN

    제품 : RMAN

    PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN
    =====================================================
    PURPOSE
    RMAN을 이용하여 Test Backup을 수행하기 위한 정보를 제공한다.
    EXPLANATION
    8.1.7 부터 RMAN에서 BACKUP command에 VALIDATE keyword를 사용할 수 있게 되었다
    이 명령의 수행은 다음과 같은 작업을 수행한다.
    - Datafile의 physical and logical corruption을 check한다.
    - 모든 database file들이 존재하는지, 그리고 올바른 위치에 있는지를 검증한다.
    RMAN은 실제적으로 backupset을 생성하지 않는다 그러나 그것들이 backup될 수
    있는지 없는지를 결정하기 위해서 기술된 file들을 scan한다.
    BACKUP VALIDATE 는 backup job을 수행시 수행되는 것을 제외하고는
    RESTORE VALIDATE와 거의 비슷하다.
    EXAMPLE
    아래와 같은 command들을 수행하여 backup하고자 하는 database file과 archived redo
    log들이 실제로 backup될 수 있는지를 검증할 수 있다.
    RUN {
    ALLOCATE CHANNEL ch1 TYPE 'sbt_tape';
    BACKUP VALIDATE
    DATABASE
    ARCHIVELOG ALL;
    Note: MAXCORRUPT or PROXY parameter는 VALIDATE option과 함께 사용할 수 없다.

    Clint,
    I ran the command lines you wrote me after i placed the database in Startup MOUNT state, RMAN gave error messages that the database needs to be open:
    RMAN> SQL 'ALTER TABLESPACE USERTB2 OFFLINE IMMEDIATE';
    sql statement: ALTER TABLESPACE USERTB2 OFFLINE IMMEDIATE
    RMAN-00571: ===========================================================
    RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
    RMAN-00571: ===========================================================
    RMAN-03009: failure of sql command on default channel at 11/04/2005 15:31:33
    RMAN-11003: failure during parse/execution of SQL statement: ALTER TABLESPACE US
    ERTB2 OFFLINE IMMEDIATE
    ORA-01109: database not open
    Then I ran the same command lines after I opened the database, RMAN gave error messages that "offline immediate disallowed unless media recovery enabled":
    RMAN> SQL 'ALTER TABLESPACE USERTBS2 OFFLINE IMMEDIATE';
    sql statement: ALTER TABLESPACE USERTBS2 OFFLINE IMMEDIATE
    RMAN-00571: ===========================================================
    RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
    RMAN-00571: ===========================================================
    RMAN-03009: failure of sql command on default channel at 11/04/2005 15:48:17
    RMAN-11003: failure during parse/execution of SQL statement: ALTER TABLESPACE US
    ERTBS2 OFFLINE IMMEDIATE
    ORA-01145: offline immediate disallowed unless media recovery enabled
    I am stuck again and need your help!
    Thank you,

  • Backup using RMAN

    Hi,
    I want to perform the first backup with RMAN and I used this command and I got error:
    RMAN> BACKUP AS COPY DATABASE;
    can not backup or copy active file in noarchivelog mode.
    But in order to turn on the log_mode to ARCHIVELOG, first I need to do shutdown the db and perform the backup. Right?
    So how can I get my first backup using RMAN if the log mode is in NOARCHIVELOG mode?
    I also performed controlfile autobackup on but I'm not sure the controlfiles are being backed up. How can I verify this and where I can find the controlfile backup file?
    Thanks,

    Hi
    Yes, you must shutdown the database and set it to start in ARCHIVELOG mode.
    After that you can connect to the rman catalog and the target database and execute a backup.
    eg. RMAN> backup database;
    You can search other example posted by me:
    eg.
    - Re: Backup with RMAN
    - Re: How do i set up this backup strategy?
    To be sure that you backed up your control file you can issue the rman-command:
    RMAN> list backup of controlfile summary;
    Bye, Aron

  • Error in Database backup using RMAN.

    Hi
    While taking full online backup using RMAN i got the following error.
    ORA-19566: exceeded limit of 0 corrupt blocks for file /oracle/DEV/sapdata2/dev640_6/dev640.data6
    Please help me how to resolve this issue.

    Hi,
    Please perform DBverify Job and Also analyze the alert<SID>.log file for your Database to get more information about such logical or physical corruption.  You may require Block level recovery for the complained DB Files. Please refer this useful document " [Early Detection and Correction of Data Block Corruptions Using RMAN |http://www.ioug.org/client_files/members/select_pdf/04q4/RMAN.pdf]" and share the same with your Oracle DBA.
    You can execute the following commands to get information about corrupted block(s), if its there.
    select * from v$backup_corruption;
    select * from v$database_block_corruption;
    Regads,

  • Can u we take online redo log backups using RMAN......can any one guide me

    can u we take online redo log backups using RMAN.....in 1og

    'Backup' solution for online redo logs is multiplexing (members of a group on different independent drives).

  • Can I Scheduled Backups Using RMAN ?

    Hi,
    Can I schedule Backups using RMAN without depending on Any O/S utilities....
    If ,Yes......Let Me Know How it sis possible.....
    Thanks In Advance.....

    Yes, easiest way is Enterprise Manager. Otherwise you have to define your own DBMS_SCHEDULER tasks.

  • HT201250 Can I do a backup using Time Machine on a server, or it needs an external drive only?

    Can I do a backup using Time Machine on a server, or it needs an external drive only?

    Time Machine can back up to a server. The drive or partition used still needs to be formatted Mac OS Extended (Journaled).

  • Less redo generates at the time of online backup using RMAN

    Hi,
    can someone eleborate that why less redo generates at the time of RMAN online backup in comparison of manual hotbackup.
    Thanks

    A manual hot backup (aka "OS backup" or "scripted backup") cannot handle fractured blocks. This happens when a backup command is copying out blocks from a datafile at the same time as DBWR is updating blocks. The Oracle Block Size (8KB) is generally a multiple of the OS Block size (512Bytes to 4KB or 8KB, depending on the filesystem / raw device and how the OS command copies blocks out). It is possible for DBWR to write 8KB and the OS backup utility to be concurrently reading the same Oracle block as, say, two different 4KB reads. The first half of the Oracle block may be read by one OS call and the second half by another OS call -- the two halves would be inconsistent with each other if Oracle were writing the database block at the same time.
    (Therefore a restore of such a backup would give you an inconsistent -- i.e. fractured -- block, which would be logically corrupt).
    In order to handle such issues, after a BEGING BACKUP is issued, for every first change to a database block, the whole block is written to the redo stream, not just the change vectors. (If the same database block is subsequently modified while in BACKUP mode, it is only the change vectors that have to be written to the redo stream). Once the END BACKUP is issued, the redo stream does not need to capture whole database blocks.
    If such a backup is restored, it still has fractured blocks. However, when applying the ArchiveLogs generated during the Backup, each such fractured block is "automagically repaired" because a whole image is restored from the ArchiveLog. (Subsequent changes are replayed as changes through the change vectors).
