Recover missing datafile (no backup exists)

hi, m having a problem. when i try to start oracle at a clients site, i get the following error. and they do not have any backup datafile at all.

Hello,
You wrote:

Do you have a Backup of the database (before adding a datafile) and the archived log from this Backup, or you haven't any backup of the all
database ?
In the first case. By applying the archived log you'll have the following error:
ORA-00283: Recovery session canceled due to errors
ORA-01244: unnamed datafile(s) added to controlfile by media recovery
ORA-01110: data file 14: '/mantasDB/oradata/mantasde/bus2_data_file01.dbf'Then, you'll have to create manually your datafile, for instance, as follow:
select name from v$datafile where file#=14;
NAME
UNNAMED0014
alter database create datafile 'UNNAMED0014' as '/mantasDB/oradata/mantasde/bus2_data_file01.dbf';Afterwards, you could restart the recovery.
But, if you don't have backup at all, the situation is very bad, you may lost the datafile.
Hope it can help.
Best regards,

Recovering a datafile from backup in different server

Hi All,
I usually take hot backup of datafiles to different server like this because i dont have enough space in same server. I
SQL> alter tablespace XXXX begin backup;
host scp /bu1/oradaTA/XXXXX/XXXXX [email protected]:/db1dw/oradata/backup/dec2010/XXXX
alter tablespace OPS end backup;
If i want to recover the datafile can i normally do the offline drop of that datafile and copy the datafile from backup which is in differnet server thorugh scp and make the datafile online??? and the database is in archivelog mode but i dont care abt the log files. i just need to recover the datafile as it was from last backup.
or do we need to use any recover datafile commands?? if need to use any recover datafile command from where it will recover the datafile??
i dont have any scripts for backup or recovery , i just take manual scp of the datafiles.
Help plzz, thanks in advance.....

SQL> alter tablespace XXXX begin backup;
host scp /bu1/oradaTA/XXXXX/XXXXX [email protected]:/db1dw/oradata/backup/dec2010/XXXX
alter tablespace OPS end backup;What is the version you are using? is it 9i if not you can peform backup at database level instead of tablespace level.
If i want to recover the datafile can i normally do the offline drop of that datafile and copy the datafile from backup which is in differnet server thorugh scp and make the datafile online??? and the database is in archivelog mode but i dont care abt the log files. i just need to recover the datafile as it was from last backup.Why offline drop to recover? Are you sure what are you doing?
or do we need to use any recover datafile commands?? if need to use any recover datafile command from where it will recover the datafile??1) alter system switch logfile;
2) select max(sequence#) from v$archived_log;
For Ex:
Sequence -- 100
3) alter database begin backup;
4) copy all the datafiles to another server(bcoz you not have space in same server)
5) alter database end backup;
6) select max(sequence#) from v$archived_log;
For Ex:
Sequence -- 110
Then copy these generated 10 archives to new server also.

How to fix a missing datafile with status recover

Dear all,
We have Oracle 10 database. And we create a datafile by mistake, and also by mistake we drop the datafile.
Now the condition is, the datafile is missing but still mentioned in control file, and produce an error every time we do a backup since there's a file missing.
If we select from $vdatafile, the datafile status is recover.
We tried to offline the datafile, but its no help.
How to fix this?
Thanks.

Sorry to bump this thread again,
I tried to get the same error in a Oracle sandbox server.
I deleted a datafile, so i got a missing datafile, and then i offlined the datafile.
Then, i created a backup control file and deleted line that refer to the error datafile, and then run it as a sql script to create a new control file.
But when a new control file was created, the control file got a missing datafile and offlined it automatically.
This is the control file backuped to a trace file, please notice datafile DATA00001

RMAN-05556: not all datafiles have backups that can be recovered to SCN

Oracle 11.2.0.2 SE-One
Oracle Linux 5.6 x86-64
Weekly refresh of a test db from prod, using rman DUPLICATE DATABASE, failed with “RMAN-05556: not all datafiles have backups that can be recovered to SCN”
Background Summary:
Weekly inc 0 backup of production starts on Sunday at 0100, normally completes around 1050. Includes backups of archivelogs
Another backup of just archivelogs runs on Sunday at 1200, normally completes NLT 1201.
On the test server, the refresh job starts on Sunday at 1325. In the past this script used a set until time \"to_date('`date +%Y-%m-%d` 11:55:00','YYYY-MM-DD hh24:mi:ss')\"; -- hard-coded for ‘today at 11:55’.
For a variety of reasons I decided to replace this semi-hard coding of the UNTIL with a value determined by querying the rman catalog, getting the completion time of the inc 0 backup. This tested out just fine in my vbox lab, even when I deliberately drove some updates and log switches during the period the backup was running. But the first time to go live I got the above reported error.
Details:
The key part of the inc 0 backup is this (run from a shell script)
export BACKUP_LOC=/u01/backup/dbprod
$ORACLE_HOME/bin/rman target=/ catalog rman/***@rmcat<<EOF
configure backup optimization on;
configure default device type to disk;
configure retention policy to recovery window of 2 days;
crosscheck backup;
crosscheck archivelog all;
delete noprompt force obsolete;
delete noprompt force expired backup;
delete noprompt force expired archivelog all;
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '$BACKUP_LOC/%d_%F_ctl.backup';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '$BACKUP_LOC/%U.rman' MAXPIECESIZE 4096 M;
sql "alter system archive log current";
show all;
backup as compressed backupset archivelog all delete all input format "$BACKUP_LOC/%U.alog";
backup as compressed backupset incremental level 0 database tag tag_dbprod;
sql "alter system archive log current";
backup as compressed backupset archivelog all delete all input format "$BACKUP_LOC/%U.alog";
list recoverable backup;
EOF
The archivelog-only backup (runs at noon) looks like this:
export BACKUP_LOC=/u01/backup/dbprod
$ORACLE_HOME/bin/rman target=/ catalog rman/***@rmcat<<EOF
configure backup optimization on;
configure default device type to disk;
configure retention policy to recovery window of 2 days;
crosscheck backup;
crosscheck archivelog all;
delete noprompt force obsolete;
delete noprompt force expired backup;
delete noprompt force expired archivelog all;
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '$BACKUP_LOC/%d_%F_ctl.backup';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '$BACKUP_LOC/%U.rman' MAXPIECESIZE 4096 M;
sql "alter system archive log current";
show all;
backup as compressed backupset archivelog all delete all input format "$BACKUP_LOC/%U.alog";
list recoverable backup;
EOF
And the original refresh looked like this:
>> a step to ftp the backups from the prod server to the test server, and some other housekeeping <<, then
cd /backup/dbtest
echo "connect catalog rman/***@rmcat" > /backup/dbtest/dbtest_refresh.rman
echo "connect target sys/*******@dbprod" >> /backup/dbtest/dbtest_refresh.rman
echo "connect auxiliary /"             >> /backup/dbtest/dbtest_refresh.rman
echo "run {"                           >> /backup/dbtest/dbtest_refresh.rman
echo "set until time \"to_date('`date +%Y-%m-%d` 11:55:00','YYYY-MM-DD hh24:mi:ss')\";" >> /backup/dbtest/dbtest_refresh.rman
echo "duplicate target database to DBTEST;" >> /backup/dbtest/dbtest_refresh.rman
echo "}" >> /backup/dbtest/dbtest_refresh.rman
So, my mod to the refresh was
bkup_point=`sqlplus -s rman/***@rmcat <<EOF1
set echo off verify off feedback off head off pages 0 trimsp on
select to_char(max(completion_time),'yyyy-mm-dd hh24:mi:ss')
from rc_backup_set_details
where db_name='DBPROD'
and backup_type='D'
and incremental_level=0
exit
EOF1`
cd /backup/dbtest
echo "connect catalog rman/***@rmcat"     > /backup/dbtest/dbtest_refresh.rman
echo "connect target sys/*******@dbprod"    >> /backup/dbtest/dbtest_refresh.rman
echo "connect auxiliary /"                >> /backup/dbtest/dbtest_refresh.rman
echo "run {"                              >> /backup/dbtest/dbtest_refresh.rman
echo "set until time \"to_date('${bkup_point}','YYYY-MM-DD hh24:mi:ss')\";" >> /backup/dbtest/dbtest_refresh.rman
echo "duplicate target database to DBTEST;" >> /backup/dbtest/dbtest_refresh.rman
echo "}"                                  >> /backup/dbtest/dbtest_refresh.rman
Now the fun begins.
First, an echo in the refresh script confirmed the ‘bkup_point’:
=======================================================
We will restore to 2013-08-25 10:41:38
=======================================================
Internally, rman reset the ‘until’ as follows:

Notice the slight difference in time between what is reported in the LIST BACKUP and what was reported by my query to the catalog.
Continuing with the backup list, the second archivelog backup in the script generated six backupsets. The fifth set showed:

Notice the availability of the archivelogs including the referenced scn.
Investigation of the ftp portion of the refresh script confirmed that all backup pieces were copied from the prod server.
So what am I overlooking? Having reverted back to the original script to get the refresh completed,

So, technically, you only need the database and archivelogs backed up by the database script and not the noon run of the archivelog backup.

sql "alter system archive log current";
backup as compressed backupset archivelog all delete all input format "$BACKUP_LOC/%U.alog";
Yet, why does backupset 5 of the noon archivelog backup show archivelogs from 10:30 to 10:40 if they had been deleted by the database backup script which has a delete input ? It is as if the database backup script did NOT delete the archivelogs and the noon run was the one to backup the archivelogs (again ?)
No, that is from the morning full backup. Note the 'Completion Time" of 25-Aug-2013 10:54:53
However, the error message seems to point to a datafile. Why would reverting the recovery point to 11:55 make a difference, I wonder.
As do I.
Also puzzling to me are the times associated with the completion of the backups. I don't recall ever having to scrutinize a backup listing this closely so I'm sure it's just a matter of filling in some gaps in my understanding, but I noticed this. The backup report (list backup;) shows this for the inc 0 backup:

I hope this posts in a readable, understandable manner. I really struggeled with the 'enhanced editor', which I normally use. When I pasted in blocks from the rman report, it kept trying to make some sort of table structure out of it .... guess I'll have to follow that up with a question in the Community forum ....

MISSING datafile

Dear Experts,
I am working on ORACLE 10g(Windows XP), database in archivemode
I have backup controlfile to trace after that I added new tablespace tb1(OMF), now I delete all the control files and recreate the controlfile using script generated in trace.
But I am unable to recover the datafile(TB1),

How to recover system datafile???

Hello,
Do you guys have any idea how to recover SYSTEM datafile if the datafile is missing and it's not being back up ?

Dear Suhaimi,
The only possible way of recovering the SYSTEM tablespace (and its datafiles) is from the Hot or Cold backups taken earlier. For ensure complete recoverability, I advise you to run your database in ARCHIVELOG mode and take regular online backups.
Ciao!

How to recover missing purchased items from my old region???

Hi,
Before 2 months ago I'm tried to change my region in the Apple Store and I was have a problem it I can not change the area until the reset my balance to 0 and it was I have a balance of 0.40 pounds, I contacted with the technical support at Apple and they told me should reset your balance to 0, but the balance was only 0.40 pounds and I can not buy any product because that amount is too little, So they suggested me to reset my balance to I can change my region and I have accepted this and they have already reset my balance to 0 and then was able to successfully change the region .
Now I have another problem which I can't to recover missing purchased items from my old region !!!
How to recover missing purchased items ????

You cannot use the iTunes store there any longer just as you can no longer use the food store you used to visit. Unless you can change your country back to the one you used to use you no longer have access to purchases made there which is why it is important you keep backups of all purchases made there.
The iTunes Store in a country is intended only for use by that country's residents, and only while they are in the country. To use the iTunes Store in a country you need a credit card (or other card type if acceptable in a country) issued in that country, billed to an address in that country, and also be physically present in that country when using the store. You are also restricted to waiting 90 days between country changes.
E.g., "The iTunes Service is available to you only in the United States, its territories, and possessions. You agree not to use or attempt to use the iTunes Service from outside these locations. Apple may use technologies to verify your compliance." - http://www.apple.com/legal/itunes/us/terms.html#SERVICE

yes it is a datafile corruptionYou did not say how you defined that's a datafile corruption. You provide minimum to zero information.
I just need to bring the database up,no need any exact data
I can refresh from prod laterThen drop and recreate database. Basically and since you are not in archive mode, no recover is possible. Period.
Nicolas.Hi,
How did you come to the conclusion that your datafile is corrupted? Can you provide and supported logs?

Archive logs are missing in hot backup

Hi All,
We are using the following commands to take hot backup of our database. Hot backup is fired by "backup" user on Linux system.
=======================
rman target / nocatalog <<EOF
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '$backup_dir/$date/%F';
run {
allocate channel oem_backup_disk1 type disk format '$backup_dir/$date/%U';
#--Switch archive logs for all threads
sql 'alter system archive log current';
backup as COMPRESSED BACKUPSET database include current controlfile;
#--Switch archive logs for all threads
sql 'alter system archive log current';
#--Backup Archive logs and delete what we've backedup
backup as COMPRESSED BACKUPSET archivelog all not backed up delete all input;
release channel oem_backup_disk1;
allocate channel for maintenance type disk;
delete noprompt obsolete device type disk;
release channel;
exit
EOF
=======================
Due to which after command (used 2 times) "sql 'alter system archive log current';" I see the following lines in alert log 2 times. Because of this all the online logs are not getting archived (Missing 2 logs per day), the backup taken is unusable when restoring. I am worried about this. I there any to avoid this situation.
=======================

All thanks you for help, pleas find additional information. I goth the following error as log sequence was missing. Everyday during hotbackup, there are 2 missing archive logs, which makes our backup inconsistent and useless.

Recovery of a lost datafile without backup

Its the demo for recovery of a lost datafile without backup,but you should have database in archivelog
in order to make complete recovery,otherwise in noarchivelog mode you may lose some data.Every steps is
self explainatory so i feel need'nt to add some textual description during demo
If any findings can be elaborate more please do comments.

How to recover missing notes on an iphone

How can I recover missing note on an iphone. I lost them when I deleted an old buisness email account that is no longer operational.

Have you been backing up the phone? You might be able to recover the note if you restore to a backup that was made while the note was on the phone. It might not work though, if the note was resident on the business account and was being synced to the phone that way.

How to recover missing notes on iPad

How do I recover missing notes on the iPad?

If you backup on a regular basis and the notes that you want to recover are in the backup, you can restore from a backup to retrieve the notes. Everything in that backup will be restored to the iPad if you choose to do this.

How to recover missing data from PCL4 cluster

Hello experts,
Is there any way to recover missing data from PCL4 cluster ?
We recently found that some data related to W2 production run for past years was missing in the PCL4 cluster. Tables T5UXX & T5UXY has entries with the filing dates but certain data is missing in the cluster related to those table entries.
Would there be any specific reason for such a data loss ?
Has anyone come across this issue earlier and found resolution on the same ?
Any feedback is appreciated.
Thanks,
Dipesh.

When you delete PCL4 entries for production runs, the corresponding
control information in tables T5UXX and T5UXY also will be deleted. A
control number may be used for more than one Form number (in Tax
Reporter control tables). Therefore, if a control number that is
assigned to the Form number to be deleted was also assigned to other
form numbers, then this control number information from T5UXY will not
be deleted. These details will be displayed in the program results.
However, if all Form numbers that were assigned to this particular
control number were deleted, then the control information in table T5UXY
for the control number will be deleted automatically as the last
dependent Form number is deleted."
Following we have two questions:
o Was PCL4 deleted?
o Did the W2 generate without errors?
Basically if the PCL4 data is corrupted, then we have 2 options to
rebuild the PCL4 Cluster:
1. Delete the existing PCL4 & rerun the production run with the same
   As of date.
2. Overwrite the production results without deleting PCL4 data but with
   different As of Date.
If the Employee data is not changed after your
actual production run then overwriting the results will not cause any
difference in the PCL4 data.
Secondly, if you dont want PDF spools or magmedia layouts to be
generated during overwriting of production run, then kindly uncheck
the following on the PU19 screen, so that only PCL4 data is rebuild :
1. Uncheck Employee Copy
2. Uncheck Authority Copy
3. Uncheck Magnetic table"

Recover a wrong cold backup

Hi, I had a 9i database in NO ARCHIVELOG mode in a W2003 enviromente. OS hard disk was broken with Oracle instalatión and instance was fallen.
After, I can recover all datafiles, redo, controlfiles and parameter file. I´m trying recover database in another server using RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL; command but when Oracle needs the redo file that contain SCN 573 I put the path but nothing ocurr. Then if I put SELECT * FROM V$LOGFILE; I can see that this log file is in INVALIDATED status.
Another way to recover this database?
But first... Is possible recover this database with a no consistent shutdown of the database?
Thanks...

Hi,
NO ARCHIVELOG mode Never go for "NO ARCHIVELOG mode " ..
After, I can recover all datafiles, redo, controlfiles and parameter file. I´m trying recover database in another server using RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL; command but when Oracle needs the redo file that contain SCN 573 I put the path but nothing ocurr. Then if I put SELECT * FROM V$LOGFILE; I can see that this log file is in INVALIDATED status.As you database is not consistent - with respect to crash happened you need to cancel and go for resetlogs.
Since, Archive logs are not there as you DB is not supported. So Until the correct and valid online redo logs the recovery happens as per my knowledge.
