RMAN :: Backup Restore Instance And Tablespace
Apr 18, 2013
We are managing a huge amount of data warehouse on oracle 11.2.0.3.0. We need to take backup using rman of some tablespace not the whole database backup.
we need a backup strategy in which we can restore the backup of some tablespace plus oracle instance if any disaster occur.
I have taken backup using rman on test db of system , sysaux , user tablespace then i restore these tablespace successfully and make the remaining tablespace offline , but while open the database it show me below error.
My question is how i backup using rman so that in case of disaster i restore oracle instance plus specific tablespace not full database.
ERROR at line 1:
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: 'C:APPADMINISTRATORORADATASYSTEMSYSTEM01.DBF'

i want to clone the test db to dev db but i dont want default users and tablespaces(SYS,SYSAUX,...) in the test db datapump and exp are not working, then contacted ORACLE support and they concluded that test db sysaux was corrupted.i took RMAN all tablespace bkup except default tablespaces. then created new database using DBCA and now i want to restore and recover all those test db tablesapces but while i'm doing restore its saying
RMAN> restore tablespace MAIN_DATA;
Starting restore at 07-SEP-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=129 device type=DISK
creating datafile file number=20 name=/opt/oracle/oradata/DEV71/main_data01.dbf
restore not done; all files read only, offline, or already restored
Finished restore at 07-SEP-12
i created all tablespaces in dev same as test db,

I have taken the backup of a tablespace using the below mentioned command.
run
{
allocate channel c1 device type disk;
backup tablespace tcs_tbs;
}
Now I after even after one month or one year I want to restore the backup on my same database to bring the tablespace to the previous position.
Is it possible to restore even after one year, Is retention period gonna play its role in this?

We want to keep the Guaranteed restore point for week but unfortunately we don't have enough flash space in the server. Is it possible to backup the flashback log(restore point logs) through rman and send bkp file to tape? how to restore the database in new server until Guaranteed restore point.

I'm using Oracle Standard edition 11gR2, actually that's why I'm posting this thread because I can't use TRANSPORT TABLESPACE feature.
I need to restore and recover two tablespaces, backed up in source database in another database. The destination db has been duplicated from the source db a couple of days ago so the structure is identical.
I cannot use Data Pump on this specific tablespace, because it causes some strange behavior in our application. So I took a backup from tablespaces and now I'm looking for a solution to restore and recover it in another db.
Is there any command to restore a tablespace from a specific file? I googled a lot and no luck so far..
P.S: I use controlfile instead of recovery catalog.

We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}
exit
Is there a way on how to let RMAN use the latest backup pieces instead?

We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in:
//192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod
Instance created
-- I created the relevant folder hierarchy under <ORACLE_BASE>
directory
-- Then, I created the relevant directories for Oracle Database, as
follows:
--a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK
- INCR_MTDPROD_20110621_480_7.BAK
And only see these two files:
- C-2169285856-20110527-03
- C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run {
allocate channel c1 type disk maxpiecesize=4G;
CROSSCHECK archivelog all;
backup
incremental level 0
format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_
[code]....
This is the backincr.sql:
run {
allocate channel c1 type disk maxpiecesize=4G;
CROSSCHECK archivelog all;
backup
incremental level 1 cumulative
format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANINCR_

We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.

I am attempting to use an rman backup form our live server to restore live data over an existing dev database with a different name. I cant use the duplicate command as the versions of oracle are different (10.2.0.4 EE on live, 10.2.0.5 SE on dev) So I copied the backup sets including an autobackup control file onto the dev server. I set the ORACLE_SID to the DEV version (SUN43DEV) and startup nomount and restore controlfile from the backup location. This works and restored the live controlfile. However, I then wanted to mount the database and catalog the backupsets before making a note of the last archivelog etc and restoring the backup with set newname options. But when I try to mount the database I am told that the database has a different name (SUN43 is not SUN43DEV). I read somewhere that I need to set the ORACLE_SID to the live value (SUN43) and restore as that, then use nid TO RESET THE DBID and DATABASE NAME. However, my tnsnames on DEV has no entry for the live database, and we do not have any service defined through ORADIM for the live instance on the dev server. Should I be creating an entry in DEV tnsnames that actually looks at the LIVE server? or do I need to create a service and tns entry etc for SUN43 on my DEV server pointing at the DEV server I have not seen any mention in instructions of creating a service or adding the entry to tnsnames, or indeed adding an entry to the listener for the original live sid. I am worried that if I actually point to the live server then the restore would be attempted on the live server not dev even though I am running it from Dev.
Also, do I need to drop the existing database on DEV before I restore or will RMAN just restore over the top of it?
Finally, if I try to add an entry to the LISTENER.ORA for the new sid, when I stop and start the listener, or reload, the entry is not recognised. I also noticed that the existing SUN43DEV entry is not in there either, yet I can still use that SID - I am assuming that is because the listener is not being used and the sid is recognised from the existence of the service in windows services instead?

create a backupset, tag it, and restore it. You could say that what I'm trying to achieve is analogous to a flashback, but rather than specifying a timestamp, I'd like to simply restore the entire db to exactly what was there when the tagged backup was taken.Here is the RMAN script I am using for the backup procedure:
run {
#allocate channels
#ALLOCATE CHANNEL FOR DEVICE TYPE DISK;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
#backup database
BACKUP FULL DATABASE TAG='latest' PLUS ARCHIVELOG TAG='latest' DELETE INPUT;
[code]....
I'd like to take these backups in online mode, and I've tried taking both a consistent and inconsistent backup modifying the above script.Additionally, I'm using the following restore script to try to revert the database to the state when the backup set was taken (and am testing the data being restored by deleting some data entries after taking the backup):
run {
#shutdown db (should be done already)
SHUTDOWN IMMEDIATE;
#mount db
STARTUP NOMOUNT;
#show RMAN settings
SHOW ALL;
[code]...
When performing the restore, I dont see the data backed up, rather I see the latest data still in the database. why the state of the db is not getting reverted to the backupset with tag='latest'.Finally, here below I've listed the rman settings for reference:
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ### are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default

I am doing some test, seeking your expert opinion.I have a database and have the following backup strategy.
1) Database running in archive log mode.
2) First I backup all the table space excluding one tablespace 'DP_TS_LOB'.
RMAN> CONFIGURE EXCLUDE FOR TABLESPACE 'DP_TS_LOBS';
RMAN> BACKUP DATABASE;
3) I take a separate Backup of DP_TS_LOB tablespace.
RMAN> BACKUP TABLESPACE DP_TS_LOB;
4) I backup all the archived redo logs.
RMAN> SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
RMAN> backup archivelog all delete input;
Now I wanted to restore the database from the backup excluding the DP_TS_LOB and bring it up and running. DP_TS_LOB is huge and used only on certain work flows. I don't want the database to be down until we restore DP_TS_LOB. I wanted to restore all the other tablespace and bring the database up operational and restore and recover the DP_TS_LOB tablespace datafile's in background taking the datafiles of DP_TS_LOB tablespace offline.I tried the following but unsuccessful.
RMAN> restore controlfile to 'g:ctl_bckctl_01' from autobackup;
RMAN> restore spfile to 'g:ctl_bckspfile' from autobackup;
RMAN> sql "create PFILE = ''G:ctl_bckPFILE'' from SPFILE = ''G:ctl_bckSPFILE''";
Update the new parameter with new control file name. Copied the control file and parameter file to corresponding location.
RMAN> startup nomount pfile=D:appdivaproduct11.1.0db_1databasepfile;
RMAN> restore database skip tablespace 'dp_ts_lob';
RMAN> alter database mount;
RMAN> sql 'alter database datafile 8 offline'; ==> datafile of DP_TS_LOB tablespace.
First I assumed "Recover Database" will only recover online database files. But got the following error.
RMAN> recover database;

I have to test a hot rman backup on testing environment and I have some doubts.
STAGE
Server 1
production database (linux)
backup folder on cifs share windows server
Server 2
testing database (linux)
First I installed linux on same network, I gave it access to cifs backup resource, then I installed the same database version than production environment, then I create a typical database with only same database production name. Also the Linux partitions between linux servers are different.
What oracle procedure must I apply?

I want to restore my database from server x to server y.
The control files on server x are named [$ORACLE_SID]_control01.ctl and [$ORACLE_SID]_control02.ctl.
We have an auto backup of the control files.
When I restore the control files on host y, (from autobackup) the restored controle files have other names: control01.ctl and control02.ctl. After the restore and recover (which goes well) the database does not start correctly.

7 of days ago Full backup has been taken to disk due to issues with tape devices.3 days ago tape devices have been fixed and we switched to CommVault managed tape backups. CommVault calls RMAN with following command:
run {
allocate channel ch1 type 'sbt_tape'
PARMS="SBT_LIBRARY=/usr/local/bin/simpana/Base/libobk.so,BLKSIZE=1048576,ENV=(CV_mmsApiVsn=2,CV_channelPar=ch1,ThreadCommandLine=BACKUP -jm 45 -a 2:71 -cl 9 -ins 9 -at 22 -j 294321 -jt 294321:4:1 -bal 1 -rcp 0 -ms 1 -data -ma 89 -cn oraclehost -vm Instance001)"
TRACE 0;
setlimit channel ch1 maxopenfiles 8;
backup
incremental level = 0
filesperset = 32
database
include current controlfile spfile ;
}
exit;
These backups done successfully.Then archivelog backup taken similar way.But when I issue RESTORE DATABASE PREVIEW SUMMARY; RMAN starts with Full backup set, though newer Incremental Level 0 ones are available.Why it does not use these newer ones?

I am trying to restore a backup from a live server to a dev server. Have moved nackup sets. Created a windows service to match the old sid on live system. copied the pfile from live and changed the locations of the folders to suit dev. set oracle_sid to the new sid(as created to match live)
connected to rman
startup nomount
set dbid to the live number
restore controlfile
alter database mount
catalog'd all the backupsets
[code]....
but it fails when it tries the restore .. see below ..The path it is showing is the old path from the live server, so it appears to eb ignoring my set newname statements even though they succeeded earlier - should be restoring them to d:oracleoradatasun43dev ? Does the whole thing have to be put inside one run block or can I put bits in one run block and other bits outside of it etc?

My scenario is: database is in archivelog mode.
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried:
startup mount
restore database from tag 'DLYTUE'
recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE'
( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.
