Rman backup and restore noarchive log

Hi,
We are changing our backup tools from exp to rman. For this I am trying to do
restoration in test server of oracle db running on 9.2 noarchive log.
Step 1. Taken complete backup with rman with nocatalog and include controlfile
nput datafile fno=00008 name=D:\ORACLE\ORADATA\TOTO\TOOLS01.DBF
channel ORA_DISK_1: starting piece 1 at 09-MAR-06
channel ORA_DISK_1: finished piece 1 at 09-MAR-06
piece handle=D:\DBBACKUPS\T1.BKP comment=NONE
channel ORA_DISK_1: backup set complete, elapsed time: 00:01:15
Finished backup at 09-MAR-06
Step 2. Deleted database files and control files from database directory.
Step 3. Restore controlfiles
RMAN> restore controlfile from 'd:\dbbackups\t1.bkp';
Starting restore at 09-MAR-06
using channel ORA_DISK_1
channel ORA_DISK_1: restoring controlfile
channel ORA_DISK_1: restore complete
replicating controlfile
input filename=D:\ORACLE\ORADATA\TOTO\CONTROL01.CTL
output filename=D:\ORACLE\ORADATA\TOTO\CONTROL02.CTL
output filename=D:\ORACLE\ORADATA\TOTO\CONTROL03.CTL
Finished restore at 09-MAR-06
Step 3. after database mount, try to restore datafiles, which is failed
restoring datafile 00024 to D:\ORACLE\ORADATA\TOTO\DIN36\TESTUNV1.ORA
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 03/09/2006 17:24:25
ORA-19505: failed to identify file "D:\DBBACKUPS\TOTOBKP.RMAN"
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.
Why it is looking old backup totobkp.rman which is not existing on disk ? My
backup name is t1.bkp.
Will you pl tell me where I have gone wrong ? Secondly what are the correct
steps to be followed for taking cold backup and restoration.
thanks & regards
pjp

Okay let us ponder this for a moment:-
DB NOARCHIVELOG
It does not matter when you take the backup of controlfile because the database is in mount state and no changes are allowed to the db ( Checkpoints etc. )
DB ARCHIVELOG
It does not matter when you take the backup of controlfile because the database is continuously writing to the archivelog's.
End result should not be significantly different as to worry about whether to take backup of control file before or after backup.
Thanks

  • RMAN backup and restore for Disaster Recovery

    Hi Guys,
    I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:

    Notice that it reads the backup piece from this location /oracle/app/dev/flash_recovery_are

    whereas my latest backups are stored at a different location.
    I am executing following steps at the RMAN prompt on hosta and hostb:
    hosta (production site)
    backup as compressed backupset database plus archivelog
    backup current controlfile format'/oracle/oracle_bkup/ctl_%U'
    backup spfile
    hostb (Disaster site)

    /* call the next two commands on run */
    restore database;
    recover database;
    alter database open resetlogs
    quit
    Any help will be greatly appreciated.
    Thanks,

    Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
    I take backup on Host A using:
    rman target /
    backup as compressed backupset database plus archivelog;
    backup spfile;
    quit;
    I restore the backup on Host B using:
    set dbid=13732232063;
    startup force nomount;
    restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
    shutdown immediate;
    startup force nomount;
    restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
    quit;
    /* restart rman here */
    alter database mount;
    catalog start with '/export/home/dev/restore_db/backupset' noprompt;
    restore database;
    recover database;
    alter database open resetlogs;
    quit;
    I take another backup on Host A using (notice no spfile backup this time):
    backup as compressed backupset database plus archivelog;
    quit;
    I restore the database on Host B using:
    alter database mount;
    catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
    recover database;
    alter database open;
    quit;
    Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)
    RMAN> list backup of database;

    Hi,
    You can follow this procedure
    1. take the backup to destination host
    2. restore spfile and controlfile
    3. catalog the backup with command 'catalog start with <location of backup>'
    4. use "set newname for datafile" to restore the datafile to non asm disk
    5. restore database
    6. recover database until point in time
    7. rename redolog and tempfile
    8. open database with resetlogs
    9. remove redolog group from another instance
    10. you might want to drop undo tablespace from another instance too
    11. task complete
    Cheers

  • RMAN  backup and restore in network

    Hi,
    I have already did cold backup of database using RMAN in the same disk on a linux OS. It was successful.
    Now i want to do the same backup in a different disk on a another system. Both the systems are in same network.
    Please help me

    You can name the NFS mount point anything meaningful.
    In your RMAN Backup script, you would use the FORMAT clause to specify the location where the backups are to go to.
    For example, if the filesystem from linux2 is NFS-mounted on linux as as /NFS_backup your RMAN command would be
    BACKUP DATABASE FORMAT '/NFS_backup/%U';
    BACKUP ARCHIVELOG ALL FORMAT '/NFS_backup%U' DELETE INPUT ;Look up the syntax of the formatSpec in the Backup and Recovery Reference for formats other than %U. %U generates a Unique File Name.

    You need to use "set newname" before you restore your database.
    You can refer this http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmdupad.htm
    RMAN> connect target /
    connected to target database: TEST (DBID=2033933270)
    RMAN> run
    2> {
    3> startup nomount;
    4> restore controlfile from 'location/DF_T770331608_S104_P1';
    5> alter database mount;
    6> restore database;
    7> recover database;
    8> alter database open resetlogs;
    9> }Also, you have connected to the database TEST, so is the TEST database the new database that you want to create using restore method ?
    If yes, then how the status of the database is OPEN ? The database status should be nomount before you restore the controlfile.
    If the database is not started, then:
    RMAN shows as "connected to target database: TEST (not started)
    If the database is in nomount stage, then
    RMAN shows as "connected to target database: TEST (not mounted)
    If the database is in mount stage, then
    RMAN shows as "connected to target database: TEST (DBID=xxxxxxxx, not open)
    If the database is open mode, then
    RMAN shows as "connected to target database: TEST (DBID=xxxxxx)
    In the output you mentioned, RMAN is showing the status of the database as opened. So if TEST is the database you are creating, then it has to be in nomount stage. In your case, it looks like TEST is the primary database from which you have taken the backup.

  • Backup and restore logs, quarantines cisco ironport c170

    Hello,
    Is there anyway to backup and restore logs and quarantine to another ironport c170?
    Thanks in advance.
    Alexandre

    Hello Alexandre,
    logs can easily be downloaded via FTP or SCP, there is a folder per logs subscription, i.e.
    /mail_logs
    /system_logs
    /error_logs
    Each folder contains multiple logs, thos e are with extention .s are the ones that have rolled over, while .c and .current are the ones currently written to. I would not recommend to upload them to another appliance, as this may cause problems or at least confusion. Quarantines cannot be backed up, that functionality is limited to SMAs (M-series).
    Hope that helps,
    Andreas

  • Is RMAN only way to take backup and delete Archive Logs?

    On primary db:
    ===============
    OS: Windows 2003 server 32-bit
    Oracle: Oracle 10g (10.2.0.1.0) R2 32-bit
    On Physical standby db:
    ===============
    OS: Windows 2003 server 32-bit
    Oracle: Oracle 10g (10.2.0.1.0) R2 32-bit
    Data Guard just configured. Archive Logs are properly being shipped to standby db. Is RMAN only way to take backup and delete Archive Logs from both primary and standby db? What other command can be used?
    Thanks

    No, but anything else is way more work. Without using RMAN you would have to find another way to keep track of applied logs.
    RMAN make this very simple :
    RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;Using another method would be like using the handle of your screwdriver as a hammer.

  • RMAN BACKUPS AND ARCHIVED LOG ISSUES

    제품 : RMAN
    작성날짜 : 2004-02-17
    RMAN BACKUPS AND ARCHIVED LOG ISSUES
    =====================================
    Scenario #1:
    1)RMAN이 모든 archived log들을 삭제할 때 실패하는 경우.
    database는 두 개의 archive destination에 archive file을 생성한다.
    다음과 같은 스크립트를 수행하여 백업후에 archived redo logfile을 삭제한다.
    run {
    allocate channel c1 type 'sbt_tape';
    backup database;
    backup archivelog all delete input;
    Archived redo logfile 삭제 유무를 확인하기 위해 CROSSCHECK 수행시 다음과
    같은 메시지가 발생함.
    RMAN> change archivelog all crosscheck;
    RMAN-03022: compiling command: change
    RMAN-06158: validation succeeded for archived log
    RMAN-08514: archivelog filename=
    /oracle/arch/dest2/arcr_1_964.arc recid=19 stamp=368726072
    2) 원인분석
    이 문제는 에러가 아니다. RMAN은 여러 개의 arhive directory중 하나의
    directoy안에 있는 archived file들만 삭제한다. 그래서 나머지 directory안의
    archived log file들은 삭제되지 않고 남게 되는 것이다.
    3) 해결책
    RMAN이 강제로 모든 directory안의 archived log file들을 삭제하게 하기 위해서는
    여러 개의 채널을 할당하여 각 채널이 각 archive destination안의 archived file을
    백업하고 삭제하도록 해야 한다.
    이것은 아래와 같이 구현될 수 있다.
    run {
    allocate channel t1 type 'sbt_tape';
    allocate channel t2 type 'sbt_tape';
    backup
    archivelog like '/oracle/arch/dest1/%' channel t1 delete input
    archivelog like '/oracle/arch/dest2/%' channel t2 delete input;
    Scenario #2:
    1)RMAN이 archived log를 찾을 수 없어 백업이 실패하는 경우.
    이 시나리오에서 database를 incremental backup한다고 가정한다.
    이 경우 RMAN은 recover시 archived redo log대신에 incremental backup을 사용할
    수 있기 때문에 백업 후 모든 archived redo log를 삭제하기 위해 OS utility를 사용한다.
    그러나 다음 번 backup시 다음과 같은 Error를 만나게 된다.
    RMAN-6089: archive log NAME not found or out of sync with catalog
    2) 원인분석
    이 문제는 OS 명령을 사용하여 archived log를 삭제하였을 경우 발생한다. 이때 RMAN은
    archived log가 삭제되었다는 것을 알지 못한다. RMAN-6089는 RMAN이 OS 명령에 의해
    삭제된 archived log가 여전히 존재하다고 생각하고 백업하려고 시도하였을 때 발생하게 된다.
    3) 해결책
    가장 쉬운 해결책은 archived log를 백업할 때 DELETE INPUT option을 사용하는 것이다.
    예를 들면
    run {
    allocate channel c1 type 'sbt_tape';
    backup archivelog all delete input;
    두 번째로 가장 쉬운 해결책은 OS utility를 사용하여 archived log를 삭제한 후에
    다음과 같은 명령어를 RMAN prompt상에서 수행하는 것이다.
    RMAN>allocate channel for maintenance type disk;
    RMAN>change archivelog all crosscheck;
    Oracle 8.0:
         RMAN> change archivelog '/disk/path/archivelog_name' validate;
    Oracle 8i:
    RMAN> change archivelog all crosscheck ;
    Oracle 9i:
    RMAN> crosscheck archivelog all ;
    catalog의 COMPATIBLE 파라미터가 8.1.5이하로 설정되어 있으면 RMAN은 찾을 수 없는
    모든 archived log의 status를 "DELETED" 로 셋팅한다. 만약에 COMPATIBLE이 8.1.6이상으로
    설정되어 있으면 RMAN은 Repository에서 record를 삭제한다.

    Very strange, I issue following command in RMAN on both primary and standby machine, but it they don't delete the 1_55_758646076.dbf, I find in v$archived_log, this "/home/oracle/app/oracle/dataguard/1_55_758646076.dbf" had already been applied.
    RMAN> connect target /
    RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
    old RMAN configuration parameters:
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
    new RMAN configuration parameters:
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
    new RMAN configuration parameters are successfully stored

  • Full database backup and restore

    I have a doubt on the syntax for a full database backup and restore. For a single schema, the syntax for backup & restore is :-
    exp JISPREPCORBILLINGPRD501/JISPREPCORBILLINGPRD501 owner=JISPREPCORBILLINGPRD501 STATISTICS=none
    log=JISPREPCORBILLINGPRD501_exp.log grants=y constraints=Y rows=y compress=N

    imp <userid/password> file=<export dump file location> fromuser=<export user name> touser=<import user name>
    grants=y constraints=Y rows=y log=<import log file location>
    I hope, my question is clear.
    Please, help in solving the doubt.
    regards

    hi,
    thanks, for your answer. I took a export of one schema of the database. But, when I tried to import the schema to the destination database, it showed
    imported with errors with the existence of functions showing. The commands used by me for export and import are as follows:-
    exp JISPREPCORBILLINGPRD501/JISPREPCORBILLINGPRD501 owner=JISPREPCORBILLINGPRD501 STATISTICS=none log=JISPREPCORBILLINGPRD501_exp.log grants=y constraints=Y rows=y compress=N file=JISPREPCORBILLINGPRD501

    Do, we need to drop the existing schema before importing or somethinig else. Please, help.

  • Best way to backup and restore multiple iPhones??

    hi everyone,
    I am a pretty computer savvy person and I have a friend with an iPhone and a contact list who is having some problems with it... he wants me to backup and restore his phone on my mac as he has no computer of his own (his son set up his iPhone with music etc before and is back at school now)
    so I wonder what is the easiest way to create the backup of the contacts SMS etc?
    I have my mac with the latest iTunes running os x 10.5.6
    can iTunes create multiple backups of phones? should I look into a third part solution?
    thanks for any insight.

    You can sync multiple iPods and/or iPhones with iTunes on the same computer. iTunes will create a separate backup for each iPhone as long as each iPhone has a different name.
    In regards to iTunes content, an iPhone can be synced with an iTunes library on a single computer only. If you sync his iPhone with your iTunes content, the iTunes account logged in to with iTunes when syncing will be transferred to his iPhone - but not the password for the account. If he tries to access your iTunes account too many times with the incorrect password, your iTunes account will be placed on hold.
    You can create a backup of his iPhone when the iPhone is connected to iTunes. Control-click on the name of his iPhone in the iTunes source list under devices and select Back Up.
    You can restore the iPhone with iTunes on your computer from his iPhone's backup, but do not sync his iPhone with iTunes on your computer. This should restore the contact info from the backup. The backup includes data such as most iPhone settings, email account settings, contact info, SMS messages, recent calls, call favorites, photos available in the iPhone's Camera Roll, and 3rd party app settings and data created and stored by a 3rd party app.
    The backup does not includes iTunes content including apps, photos transferred from a computer to the iPhone, and calendar events.

  • Backup and Restore VM

    I have a host server that has a C: drive and a D: drive. Right now I only have one VM running and it is located on the D: drive. I need to reformat the disk that the D: drive is on. For some reason it was created as a MBR type disk and I
    need to delete it and recreate it as a GPT disk so that I can extend the D: partition beyond 2TB. So, what is the best way to backup and restore the existing VM in this case?

    I'm not really sure what you are referring to as an import/export but I'm going to assume its something along the lines of copying the data to 1 drive, then copying the data back to another drive. Doing a file based backup and recovery would do the same
    thing.  I don't particularly like doing stuff like copy and pastes to move data (especially important data) bc there is no guarantee copy and paste actually copied everything (no logging of what it actually did) and there are alot of things that can happen
    during the copy (disk latency, network latency) that may cause data to be lost (delayed write failures).  With any good backup program you should be able to run a report for what files it actually backed up and what files failed to backup and the reason
    they failed to back up.  Same applies to restores.  Also I have seen issues where a simple copy and paste strips certain special attributes from the file.
    If file based backup/restore is not an option, then maybe a robocopy of the data would be the best solution.  I'm pretty sure using /b /copyall api should get everything as well.  And you can add a /v switch to it to get some logging.

  • Grant permission - backup and restore

    Hello Everyone,
    Please help. I would like to give permission for the domain user to a particular database in SQL Server 2014 so that it can perform backup and restore it. User should take SQL Management Studio (local) to perform backup and restore.
    My user is granted the following roles: dbcreator, public, sysadmin (I know it is weak), and has privileges on the SQL Server backup directory. What should be improved?
    Thank you for your help.
