RMAN :: Restore Point Backup And Restore To New Host
Mar 14, 2013
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.
My dev application team iwant to test their application, and once that is done they want to recover to point in time. In my case they would do that after 9.0Am and once that is done they want the state of the database back to 9.0Am
What i am planning to do is:create a restore point at 9.0Am and once application testing is done recover until restore point. ..But i was suggested not to do that way instead my Lead want me to use just recover until timestampI asked what is the difference in doing in my way,the answer i got is by using recover until restore point, the recover process cannot apply incremental level 1 backups and it just restores to a point of incremental level 0, it looked strange to me.
i have the performed level 0 rman backup on 15th feb 2013, and after that i have incremental 1 and archives and controlfile backup. Before this no backup is the database.
Now i want to restore it to 12th feb 2013.so is there any ways to restore the database to that point time.can we restore controlfile to point in time.
I am trying to restore 11gr2 database to point in time. using following steps:
Control files are fine, that are not restored.
RMAN> run { set until time "to_time('2012-12-13 12:12:00','YYYY-MM-DD HH24:MI:SS')"; } RMAN> restore database; RMAN> recover database; RMAN> alter database open;
Here my problem is it is restore complete data what ever i was having, but i don't was it, i has to restore up to specified time only.
I have 2 server install oracle : server 1 and server 2
server 1 run database DB01
i use rman backup DB01 ( this command : BACKUP FULL DATABASE PLUS ARCHIVELOG DELETE INPUT; ) and move ( The database backup pieces , Controlfile backup piece, The parameter file i.e init.ora file) to server 2 .
At server 2 :
After start database with init.ora file and restore controlfile error :
RMAN-03002: failure of restore command at 07/22/2011 02:56:04 RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece
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 [code]...
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_ %d_%T_%s_%p.bak'
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?
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.
We have 11gR2 2 node RAC on Linux. ASM and OMF is used for database. The database on it is backed up using RMAN. We want to test the RMAN backup by restoring it to a new database on same server.
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.

I have on PC running Windows Server 2003 named "Host A" and another Windows Server 2003 named "Host B".I made a Backup from Host A and want to restore this on Host B with following procedure.

But when i now try to access the Database Control i got following Error:„503 Service Unavailable: Servlet error an exception occurred the current application deployment descriptor do not allow for including it in this response" and the restored Datas are not included.
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;

I have no backup taken in my oracle server.Today morning i created a data file and unknowingly deleted it. Now i need to restore the datafile with its contents without using RMAN.
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:
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?

Starting restore at 14-FEB-12 using channel ORA_DISK_1 using channel ORA_DISK_2 channel ORA_DISK_1: starting datafile backupset restore channel ORA_DISK_1: specifying datafile(s) to restore from backup set
I started restoring and testing all the backups. So far I did good and I wanted to restore and test in different host. I couldn't find any online documentation regarding restore full back up in a new different server (With same OS and same version of Oracle) without RMAN catalog database.
I have installed oracle 11.2 on virtual machine and made two copy of this vm i.e vm1 and vm2...i have taken fullbackup with rman on vm1 and autobackup of control file.Now i want to restore this backup on vm2, for this i have configured channel and other setting. run following command
catalog start with '\server3database_backup manC-3507808503-20130531-00';
"C-3507808503-20130531-00" is the name of control file autobackup.
RESTORE CONTROLFILE ;
it gives me error RMAN-06496: must use the TO clause when the database is mounted or open...then i use following command
RESTORE CONTROLFILE to 'C:oracleAdministratororadataslate';
then it gives me error RMAN-06024: no backup or copy of the control file found to restore...how to restore control file to vm2
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.
