The controlfiles were corrupted due to some issue. So, I had to restore the recent backed up control file and then restore the database.
The weird thing which I have noticed is that. I tried backing up Yesterday's Control file. So, I would say that the backup pieces it should pick should be from yesterday. however, the backup pieces are getting restored from last week's backup.
In order for the following command to work:
> recover database using backup control file until cancel;
what command must precede it, is it:
> alter database backup control file to trace;
I have a problem with my control file [URL].........
What I did, I have a duplicate of the database with the invalid control file, let's call it DUMDB. I am using my control file and no recovery-catalog-db.
I recreated the control file. Now everything is working fine, new backups can be taken, restores can be made. I just need to restore a backup tagged with "LASTDEV". The control file for this backup is the invalid one. So I need a restore WITHOUT restoring the control file.
I did:
CODERMAN> catalog backuppiece '/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp';
cataloged backup piece
backup piece handle=/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp RECID=1 STAMP=761604017
CODERMAN> list backup;

Why can the data files not be found even if they are listed in the backup?
I am on 11.2.0.2.0 on Linux64.
I deleted the control file using $rm control01.ctl. But i perform the back up
rman> backup incremental level 0 database;
i have no any backup
so how can i recover the my lost control file to connect with oracle instance.
I did a hot back up like this :
--check that it is in archivelog mode
SQL> archive log list
-- the data files that will need to be backup by OS command
SQL> select sum(bytes) from dba_data_files;
SQL> select name from v$datafile;
-- note archivelog sequence before starting the hot backup (need to back the archivelog generated during the backup)
SQL> select thread#, max (sequence#) from v$log group by thread# order by thread#;
-- begin the backup
SQL> alter database begin backup;
-- use OS command to copy the datafiles
-- remember to end the backup mode
SQL> alter database end backup;
-- archive the current online redo log files
SQL> alter system archive log current;
-- REMEBER to note the MAXIMM online-redo sequence number
select thread#, max (sequence#)from v$log group by thread# order by thread#;
-- backup the control files
SQL> alter database backup controlfile to '/oradump/hbackup/O11R2/controlbk.ctl' reuse;
-- backup any archive-redo logd generated during the backup
-- select from the v$archived_log mode
-- anything thing that appear under this view is safe to backup as long you don't backup the current archive log file that is being written to.simulated a scenario, if 1 of my multiplex control is damage due to media failure ( i just delete it, seem like i got to shutdown first before i can delete it, using window bases oracle, not too sure linux allow you to delete the control file like this)
To what i understand one can restore a missing control file if you have multiplex it. so I did this :
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
-- while it is being down, i use OS command to copy a good copy of the control file to the missing controlfile location + name.
-- startup

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've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?
I have restored database with the name DB to another database called DB01
it is in STARTED status (not mounted) and it seems I can not change the name if it is not mounts, and I can not mount it because of the name, how to solve this issue if possible? I have RMAN full backup from DB on my current server which hosting the database DB01 the initdb01.ora is ready and configured with DB01
what can I do next
ORA-01103: database name 'DB' in control file is not 'DB01'
It's possible to restore a database only using the RESTORE command? (without use the recovery process)?I trying to do this using the commands:
RMAN> backup database;
RMAN> backup current contolfile;
RMAN> shutdown immediate;
RMAN> startup nomount;
RMAN> restore controlfile from '/opt/oracle/flash_recovery_area/ORCL/backupset/2012_12_04/o1_mf_ncnnf_TAG20121204T2555832_8cx71t4j_.bkp';

I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)
I want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?
restore controlfile from '/u01/rman_backup/mybak/df_768589733_7_1.bak';
I encountered error ORA-00338 while performing incomplete database recovery:
ORA-00283: recovery session canceled due to errors
ORA-00338: log 3 of thread 1 is more recent than control file
ORA-00312: online log 3 thread 1: '+DG_REDO/dbase/onlinelog/group_3.267.814820795'
Recovery Manager complete.
I performed this recovery on oracle 10g, ASM database.
1. What are possible causes behind this error ORA-00338 ?
2. This error occurs at the start of media recovery, while RMAN is applying archived logs. So does RMAN apply "online REDO" logs after applying "archived" logs required for recovery or before them ?
3. How does rman come to know that online log 3 is more recent than control file ? How can I get scn of online log & control file in my environment ?
Following are few details related to checkpoint scn/change# info. I found in my environment..Before recovery:
view
v$datafile: 642935
v$datafile_header: 642935
v$database: 642935
v$log: 640956
After unsuccessful recovery (ORA 338 :( )
v$datafile: 640917
v$datafile_header: 640056
v$database: 640906
v$log: 640906
Can we restore database password file in ASM for 11gR2 version.

View 1 Replies View RelatedI had a database on an old P4 running but the motherboard got fried. I was able to recover all the data files (.ctl and *.dbf) plus the redo logs (.log). There is no export or backup taken - I have old ones, but I need to recover the latest which only existed in the data files.
I now have Oracle installed on a new P5 machine and was wondering if it is possible to use these data files in the new database? If so, how do I go by restoring the data files?
Both the P4 and P5 where running Red Hat Linux.
Suppose I take a multi stream backup, say 3 streams.
So if a control file is backed up in say backup set 1, so is the whole control file is backed up in one backup piece or it may span multiple pieces?
A backup set may have multiple backup pieces.

View 12 Replies View RelatedI am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.
I am getting back into Oracle (from a long haul in MS only env.) and am now testing Oracle installs.I have been given a task of seeing the diff. between 12c and 10.2g...I set up 2 vms (excatly same configs) and used the same dmp file (on both env.) to restore data and settings for our jobs to run.We have some aggregated data, and cubes with DIM tables each being run on the vm machines. We run nightly jobs to rebuild our cubes.
I am supposed to see/analyze the value of 12c, and understand things might vary from company to company, but am perplexed at my result.12c is half the speed of 10.2g, both env. are the same out of the box with same dmp file and same hardware.
I am using the same dmp file, with the same jobs on each machine, with both vms having 10.2g or 12c installed out of the box as is.what default oracle settings might have changed from 10.2g to 12c that could make the exact same env. run twice as slow on the 12c?
Expectations were that out of the box with both machines running same jobs on same data (from dmp files) would have it that 10.2g would be slower than the 12c, except the 12c takes 2 times as long to run the jobs. I have reviewed every possibility as I know usually the problem is the person sitting in the chair and not the pc...but I confirmed all was identical from the one vm env. to the other, except the version of oracle out of the box.
What could be done to bring that default setting back to atleast equal time between the 2, that would give me a great starting point. Otherwise, I would have to toss this up to bloatware.
I read up a bit on the CBO, and know this might have changed in 12c.is there a way to bring it back to a backwards ealier config, so as to atleast match both env. execution plans?

I am running 10g on Linux, and last week someone messed up a database and it needs to be restored to 27 December. I am not a DBA, out regular DBA is on vacation till mid January,
I know we have archivelog on (I can see .arc files for the database), and I also have a backup of the actual data files and control files from when the database was first created. So in other words, I have all archive files and the initial data files. What i do not know is how to set the restore till December 27.
I have a quick question : -
Usually you install and create a database in one go using dbca.
Now you have the option of only installing oracle and then say next day create the database still using DBCA.
My question is how do you restore the database on another host on a machine which has only oracle software installed and no database installed.
well can a re-direct restore do the job ?
can we restore oracle database using backup using emc bcv technology? i dont have experience with bcv.

We have Oracle 10.2.0.3 database installed on Itanium server.
1. One day we found some packages got invalid & not compiling at all with error – ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], [].
2. Then we successfully restored the database from old RMAN backup of previous date that caused this error.
3. After 2 days again we found the same error in alert_prd log - ORA-00600: internal error code, arguments: [ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], [] ORA-06512: at "SYS.DBMS_STATS", line 19089 ], [], [], [], [], [], [], []
4. Then for testing we exported database using exp command & found 3 tables are not exporting because of data block corruption issue.
5. Then we truncated the data from all 3 tables and then able to export successfully.
6. After all this we manually run SYS.DMS_STATS job but found same error logged in prd_alert log.
This looks like, still database block corruption issue is there & we are unable to cure it 100% This is a production system & in very critical state now.

I want to know is there any process which makes my work less like I just need to apply all rest of the logs which are new after synchronize last time from production server that need restore and recover.
