Recover DBID

Hello All,
I'm in a situation where I have a complete failure of a server and the only means for recovery is using the backups. The big problem that I have is that I didn't make note of the DBID prior to the disaster. Is there anyway to retrieve/recover the DBID based on full backups sets (archive logs, online logs, and autobackups). This is for an XE database.
I also checked the numbering on my autobackups and they do not reflect the DBID as part of the name :(.
Any assistance will be much appreciated.
Thanks!
-Alan

My autobackup filename is: O1_MF_S_608387137_2QCOG252_.BKP and the 608387137 isn't the DBID. The reason I know this is because I have another XE instance running and confirmed that that number doesn't match it's DBID, not 100% sure why.
Unfortunately, I don't have any control files laying around. All I have are the contents of the flash_recovery folder where the backups were dumped.
That is, the ARCHIVELOG, AUTOBACKUP, BACKUPSET and ONLINELOG folders. I did have a copy of the admin folder too for some reason, and I checked the alert log to see if it would be in there but no luck.

How can I recover data from a USERS01.DBF file?

So I had a Hard Drive die and that took out the OS and the Oracle RDBMS Installation (Oracle9i Enterprise Edition, 9.2.0.6.0 on WinXP). Fortunately most of the data in the database (9.5GB worth) was in the USERS01.DBF file which was on another drive and unharmed. I was also able to salvage the CONTROL01.CTL file, but everything else from the database is corrupted and irretrievable.
I've just setup a new machine with the same version of Oracle and I created a brand new database with the same SID as before. I then tried to do:
SQL> alter tablespace users offline temporary;
Tablespace altered.
(then I swapped the USERS01.DBF file with the original one and then tried to recover it)
SQL> recover tablespace users;
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 9: 'F:\ORAHOME\ORADATA\MYDB\USERS01.DBF'
ORA-01122: database file 9 failed verification check
ORA-01110: data file 9: 'F:\ORAHOME\ORADATA\MYDB\USERS01.DBF'
ORA-01206: file is not part of this database - wrong database id
Is it even possible to do what I'm trying to? I had no backup of the USERS01.DBF file, but there should be some way to get at the data that is inside it...
any help or a pointer in the right direction is much appreciated.
thanks

Whilst this isn't a direct answer, running any form of "recovery" will require archive logs, and it doesn't appear that you have archive logs related to this data file.
If you had your system.dbf file in addition to a control file and data file, I'd imagine might have enough to bring a database online using a "cold backup" type restore.
The specific error you show references the DBID in your data file does not reference the DBID in your control file. You don't appear to have restored your control file backup. This would make your existing .dbf files now not load, though a number of them can be rebuilt, not all of them can.

Recovering lost data from a very old backup (disaster recovery)

Hi all,
I am trying to restore and recover data from an old DAT-72 cassette. All I know is the date when the backup was taken, that is back in November 2006. I do not know the DBID or anything else except for the date.
To recover this, I bought an internal SCSI HP c7438a DAT-72 tape drive on eBay and installed it on a machine running Windows 2003 Server SP2. I made a fresh Oracle 11g Enterprise Edition installation. HP tape drivers have been installed and Windows sees the tape drive without problem. To act as a Media Manager, I have installed Oracle Secure Backup. Oracle Secure Backup sees the HP tape drive without problems as well.
I have to admit my information about Oracle is not very in-depth. I read quite a lot of documents, but the more I read the more confused I become. The closest thing I can find to my situation is the following guide about disaster recovery:
http://download.oracle.com/docs/cd/B10500_01/server.920/a96566/rcmrecov.htm#1007948
I tried the suggestions in this document without success (details below).
My questions are:
1. Is it possible to retrieve data without knowing the DBID?
2. If not, is it possible to figure out the DBID from the tape? I tried to use dd in cygwin, also booted with Knoppix/Debian and Ubuntu CDs to dump the contents of the tape with dd but all of them failed to see the tape device. If there is any way to dump the raw contents of the tape on Windows, I would also welcome input.
3. Is there any way at all to recover this data from the tape given all the unknowns?
Thanks very much in advance,

Hi 845725,
If the backups were created with OSB might be you can query the tape with obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htmTo list pieces you could use <lspiece> within obtool.
http://www.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14236/obref_oba.htm#BHBBIFFEIf this works you should be able to identify the controlfile autobackup if it has the standard naming < c-dbid-date-xx > and you than know the DBID or you are able to restore a controlfile from a backup piece in the output list.
Might be you have to install 9i or 10g rdbms software as 11g was released a year later in 2007.
Anyway goodluck.
Regards,
Tycho

Recover database on the other host

I have to recover my database on the other host.

Is there a way to recover the spfile if I remove the spfile?

Hi,
Is there a way to recover the spfile if I remove the spfile?
I did a rman full db backup.
thanks.

You can user RMAN to recover your spfile, see Note 372996.1 Using RMAN to Restore and Recover a Database When the Repository and Spfile/Init.ora Files Are Also Lost, RMAN is able to startup the instance even when there is no spfile/pfile, then you can recover your spfile from your last backup.

Recovering primary using standby database

Hi all,
Here we have a dataguard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. We configured dataguard in 10g environments and we are not using grid control. And now we want to configure rman for incremental backups.After configuring we successfully took full backup in standby plus archive logs. Then as the test case we dropped one datafile from the primary and tried to recover it. It is showing the following error. Also when i tried 'crosscheck backup' from primary it is showing that all the backups taken in standby are 'expired'. But from RMAN connected to standby the same backups are showing as 'available'. Can anyone help to fix this?

Using a Standby Backup to Recover a Primary

Here's one I've been working on and would like input. We backup our standby database nightly due to resource limitation on our primary server. These backups will be used to recovery the primary in case of failure. I've successfully applied these backups to the primary but only under "nice" conditions, i.e. shutdown nicely, restore control file and restore/recover database. Of course we all know that when it hits the fan it's usually not under "nice" conditions. So to simulate a more realistic situation I remove the the two primary control files and delete the system file, in our test environment of course. Now the recovery is much more difficult and I've yet to do a full recovery in this scenario.
My question is, has anybody played with recovering a primary from standby backups?
I do realize that in a real crash of the primary the standby would be promoted to primary so this is more of a lesson in RMAN for me.

RMAN Recover database error..

Hi All,
We were trying to restore and recover one of our databases. The restore went well but the recover is erroring out. Can someone please let us know what we should do to remedy this and carry on with the recovery.
We got an error when we were trying to restore the controlfile at the begining (details below), but as you can see, it did manage to restore a copy of the controlfile successfully..
Details below.

Problem in recovering database

I Have Oracle Database 10g (10.2.0.1.0) on Windows Server 2003
I have taken full hot RMAN backup of database.
I have copied the backup files from flash recovery area.
I have one other Machine having windows server 2003 And Oracle 10g Same version. I have copied the backup files from first machine to Flash Recovery Area folder on second machine.
Now i am trying to restore the database of first machine to second machine.
1. I have created a new instance on second machice with same name as in fiirst machine.
2. I have created one ORA password file as well.
3. SET ORACLE_SID=<name of DB as it was in first machine>
4. RMAN TARGET sys/<password given in newly ORA pwd file>@<DB name> nocatalog
5. SET DBID=<dbid of old database>
6. STARTUP NOMOUNT FORCE
7. RESTORE SPFILE TO PFILE '<path of new pfile>' from '<path where backup files are there>';
8. CREATE UDUMP,BDUMP,CDUMP,PFILE,ORADATA FOLDERS where required;
9. SHUTDOWN IMMEDIATE;
10. STARTUP NOMOUNT PFILE='<path of newly created pfile>';
11 RESTORE CONTROLFILE FROM '<path of backup files>';
12. ALTER DATABASE MOUNT;
Everything work fine till here
Now my next step was
13. RESTORE DATABASE;
Then it gives error like:-
RMAN> restore database;

RMAN-06023: no backup or copy of datafile 1 found to restore
Firstly i copied backup files to flash recovery area, then i copied files to 'D:\oracle\product\10.2.0\db_1\database' as well. Because i have done it in 9i, in 9i i copied the backup files to this backup folder then while doing restore RMAN succesfully takes file from this folder & restores the database. but in 10g RMAN is not recognising the path of backup. How this problem can be solved? Or is this some different problem which i am not getting?
Waiting for reply..

Hi ORADBA,
Thanks for your response. Your solution worked. Actually there was a difference the Oracle installation on server from which i was taking backup is on E drive.
And the server on which i am trying to restore that database has Oracle installation files on D drive. That's why this confusion occurred.
But i have one query again. I am not able to recover my database fully.
Firstly i typed restore database command that worked. Thereafter i tried recover database command. that commant resulted in an error as given below. Than i typed command archive log list on SQL promt, from there i found the information of latest archive log. then i tried recover database until logseq 484 thread 1. That also didn't work. In the same situation i tried to open database i was able to open database using command alter database open resetlogs. I suppose i was not able to recover the database fully. Hi can i recover my database fully?
waiting for reply. Thanks in advance.

Urgent poblem recovering a file

Hi I just followed a tutorial on this site and I get some trouble recovering data.
Here is the output of the rman restore recovery command.
What I don't understand is that that I don't want to use tapes, I just want to use my disk
error allocating device, device type: SBT_TAPE, device name:
I made the test disk backup, it was successfull, but not the tape drive, of course I don't have one.What can i do, is there a way I can specify to restore it on disk not using tape, or is there a way I can desactive tape in oem.
Because I am just recovering from oem.

Recovering controlfile from autobackup

Hi to everyone,
I am practisisng RMAN backup and recovery in oracle 10g xe . My database is in noarchivelog mode. And I want to recover from loss of controlfile. I am performing following steps:
RMAN> STARTUP
$ mv ~/oradata/XE/control.dbf cc.bak
RMAN>SHUTDOWN ABORT
RMAN>STARTUP NOMOUNT
RMAN> RESTORE CONTROLFILE FROM AUTOBACKUP;
RMAN> ALTER DATABASE MOUNT;
RMAN> RESTORE DATABASE;
RMAN>RECOVER DATABASE NOREDO;
RMAN>ALTER DATABASE open RESETLOGS;
and database recovered successfully. But I read oracle docs that says before restoring controlfile autobackup, we need to set dbid first. How can above steps that I perform also a success.

Cannot recover control file in Oracle10g

Dear friends ,
I have to delete my three control files for testing purpose in ORacle 10g .Before Deleting , I take a backup with control file and spfile using following way :
script :
run
allocate channel t1 type disk;
backup format 'df_%t_%s_%p'
(database);}
AND OUTPUT of RMAN ,
RMAN> show all;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'C:\TEMP\ctrl_file%F';
Now when I run the restore script then it shows follwing error :

I dont know why my control files are not backed up ? can anybody plz help me ?

I can't say why what you did didn't work but I can say that using RMAN is not the best way to recover lost control files.
Lets assume you have three control files located on three different drives. It is impossible to accidentally delete all three so the best solution to losing one is to shutdown the database and copy an existing one to the location where a file has gone missing and rename it to the name of the deleted file.
Failing that you should always have a script created using:
BACKUP CONTROLFILE TO TRACE;I would only use the control files backed up by RMAN to create an auxiliary database such as a standby or for testing.

Hi all,
I am testing a new backup and restore mechanism of a 11.2 system in Linux. A third mirror of the disks from the database server has been split and mounted in a media server. An RMAN backup was taken then, on tape, using HP Data Protector. Then, in the media server again, I mounted all the disk groups and removed all the files from ASM via asmcmd. With everything cleared, I proceeded in doing the following:
1. Started up nomount using an old PFILE.
2. Initiated an RMAN session and SET DBID, connected to the target and the catalog. Restore the SPFILE in a PFILE.
3. Shutdow and started up nomount with PFILE the newly created file (edited it first to comment out CLUSTER_DATABASE parameter, as the media server is not configured for this).
4. Restored the contorl file. This was done successfully.
5. Restored the database. This was done successfully.
6. Mounted the database and attempted to recover it. I received the following error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 07/12/2013 09:42:24
RMAN-06094: datafile 1 must be restored
7. I attempted a recover from SQL*Plus; the error message was a little more helpful:
SQL> recover database using backup controlfile;
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 1: '+BT1_A_SYSTEM/bt1_a/datafile/system.259.813148661'
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: '+BT1_A_SYSTEM/bt1_a/datafile/system.259.813148661'
8. I checked my source database and the file name is as it appears above. But in the restored system, the file has a different name:
ASMCMD> pwd
+BT1_A_SYSTEM/BT1_A/DATAFILE
ASMCMD> ls -l SYSTEM*
Type Redund Striped Time Sys Name
DATAFILE UNPROT COARSE JUL 11 16:00:00 Y SYSTEM.257.820514399
9. OK. I presume that this happened because we are using OMF. But, I was expecting RMAN to specify the full file names and thus restore them with their original names. The problem is now that the control file has the original file names, which cannot be found in the media server, where the restore took place. I am wondering if I should MOUNT the database after the control file restore and before I start the database restore, so RMAN might have the opportunity of renaming the file names in the control file.
Has anyone encountered this problem? I would appreciate some help.

That is correct Hemant. I latter realised my mistake.
When I mounted the database, the control file was opened. Then I repeated the restore. RMAN, this time was able to access the control file and rename dynamically the files, as they were restored and getting their new names.
So, I think, the correct sequence of events may be:
1, Check in ASM if the disk groups are mounted (lsdg). If not, mount the disk groups (alter diskgroup <dg_name> mount;).
2. Startup nomount (if no PFILE available, create a simple one with only db_name in it).
3. From RMAN, set DBID and then connect to target and catalog.
4. restore spfile to pfile from autobackup
5. restore control file(s) from autobackup
6. alter database mount
7. restore database
8. restore archivelog all
9. recover database
10. alter database open resetlogs
In my case, this worked, by enslarge. RMAN stopped when it run out of archived redo logs.
I then attempted, via SQL*Plus:
recover database using backup controlfile until cancel
When prompted, I typed: CANCEL
That was fine, but then, when I attempted:
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 525336576 bytes disk space from 2147483648 limit
So, I needed to increase the parameter db_recovery_file_dest_size which I did (in the pfile; luckily I had available space in the disk group). I shut down and started up (mount). Then:
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-00392: log 24 of thread 2 is being cleared, operation not allowed
ORA-00312: online log 24 thread 2: '+BT1_A_RECO'
So:
SQL> alter database clear unarchived logfile group 24;
Database altered.
SQL> alter database open resetlogs;
Database altered.
SQL> select * from dual;

Happy days!

RMAN recover for testing

I want to plan some test runs on migrating my Oracle DB to 11.2 from 10.2. I understand i can't use the Duplicate command since i am changing versions. I realize that i need to running the commands restore and recover i can essentially do this. Well Can i change the name of my DB like i can in the duplicate command? Also is there a way to do this with the recover catalog and change the DBID of the new DB? Thanks.

Hello;
