I recently started reading about oracle backup and recovery concepts, and I needed to understand what is happening where we put a tablespace to a backup mode (alter tablespace tablespace_name begin backup) ?
View 10 Repliesi 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 created all tablespaces in dev same as test db,
we are using dataware house of huge amount of data I want to take backup using rman so that I restore oracle instance and specific tablespace only not full database

I have a "prj_tbl" named tablespace in a user's schema in my database. i have given 100mb size to the "prj_tbl" at the time of its creation and auto extend is open for 10mb,and now this tablespace is using nearly 3.6mb space for its data and remaining space is free,now i want to reduce the size of "prj_tbl" tablespace to 20mb and when i tried to resize it then ,
It throws an error- "'ora-03297 file contains used data beyond requested resize value oracle"
I think this message showing that my new size is small than the size of data on my tablespace but it shows free space nearly 96mb then it means my new size is larger than the size of data on tablespace. How should I reduce the size..
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?
I have taken the tablespace export it came 2.1gb and for the same user i have taken the schema export it came 5.1gb
why their is a lot of difference in size?

I was learning some recovery part in my home laptop. Database is in Archivelog, flashback mode. All of sudden, i deleted it from OS level with out taking backup of it.
When i tried to open database, it failed to start. Database is in mount mode.while trying to open, it gives message -
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: 'F:ORACLEPRODUCT10.2.0ORADATADBSYSTEM01.DBF'
I tried to create on file named "UNDOTBS01.DBF" but oracle is not recognizing it.
How many times i can do recover (TSPITR) a tablespace ? While trying to recover tspitr tablespace on 2nd time i got error message ORA-01178 file 13 created before last create controlfile,but first time it was success.

Current time :05 Apr 2011
I have to perform the TSPITR of a tablespace to recover it to a time 03-apr-2011 5 pm.Now I have done that.
Now I find that I need to actually recover it ti 04-apr-2011.Can I again recover the tablespace to 04-Apr after recovering it to 03-Apr by mistake I am not usng recovery catalog;
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;

how to recover those tablespace's datafile?What happened to earlier tablesapce backup?
We are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?
We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.

I have problem on using "delete obsolete" in RMAN.
First, let describe my backup configuration.
1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep)
2. Incremental backup for other days
3. Enable autobackup of control file
4. Backup archive log every day
5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS
6. Execute "Delete obsolete" every day
7. control file is used instead of catalog
The results observed:
1. Backup of control files older than 30 days will be deleted
2. Backup of archive log files older than 30 days will be deleted.
3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.
In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.
I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.
I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.
The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.
understanding rman scn based Backup Algorithm .. In SCN based backup do rman generate backup from archivelogs ???
View 1 Replies View RelatedI have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time
it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)

ORA-01139: RESETLOGS option only valid after an incomplete database recovery
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.

shutdown database.
Place available dbf files in the location for new database, replacing existing files.

RMAN-06428: recovery catalog is not installed
I have a doubt regarding the process the RMAN follows for restore and recovery of the database.
My Level 0 full backup completes on Saturdays at around 11 am after taking 8 hours (It starts at 3am).On Sunday, I ask RMAN to restore (on a different box) till Saturday 11:30 am.Then, after the restore is successful, I recover it till 11:45 am.
The recovery also goes fine and Iam able to clone to test box.
Till what time is the database restored? I assume its till 11 am since the L0 backup finishes at 11 am though I have asked it to restore till 11:30 am
During the recovery, ONLY the archives generated between Saturday 3 am and till the time i asked for recovery (Saturday 11:45 am ) are required. But, checking the recovery log file, i was surprised to see that RMAN has restored archive files starting from Friday 9:30 pm (Much before the time the Level 0 backup even started).
why does RMAN require the old archive log files.
