PhiriHi,
Am not sure you want resolution of which error. Moreover am not sure why on earth anybody would like to resize, if resize is not possible then drop that datafile without migrating the data.
Anyways,
1) You can query dba_segments for tablespaces, dba_extents for datafiles to get the list of objects that are affected by missing datafile
2) What issue you meant.
3) Is your databases in archive mode. And do you have all the archives from the point when you issued the command may be we could recover but all depends

Thanks very much!
Satine

Hey Werner,
Thanks very much for your help.
The reason I tried to drop the datafile is after I add the datafile to tablespace, I found the datafile failed to be created on the standby side because the parameter "db_file_name_convert"'s value were incorrect. When I created the datafile on primary side, the value of "db_file_name_convert" was,
SQL> select name,value from v$parameter where name='db_file_name_convert';
NAME                           VALUE
db_file_name_convert           /home/oracle/bill/oradata/bill, /U02/bill/oradata/billIt should be VALUE='/usr/oradata/bill','/U02/bill/oradata/bill'. For now the datafile's status on standby side is,
SQL> SELECT name,status FROM V$DATAFILE where file#=18;
NAME                                               STATUS
/U02/bill/product/9.2.0.1/dbs/UNNAMED00018         RECOVERIf the datafile on primary side could been recovered successfully, is there a way to make the datafile on standby side also correct?

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

Yes, I´m testing RMAN to be sure I will be able to sucessfully backup and recover it if necessary in the future. I never used Rman before in production environment. so I want to be sure it´s ok.

Confused with datafile status in v$datafile and v$recovery_file

Hi All,
Am facing great confused problem in prod database, accidently i created datafile so i tried to drop it by using "alter database datafile' ' offline drop"
But its showing recovery status in v$datafile and offline status in v$recovery_file.
Please inform how to resolve this issue.
Regards,
Yasser.(Oracle DBA)

You add datafiles to a Tablespace and when you remove a datafile from the database you have to drop the associated tablespace that the file had belonged to.
Exactly what actions did you take in what order to create and eliminate this datafile to and from the database?
What is the Oracle version?
What are the results of the following queries?
select ts#, file#, rfile#, status, enabled from v$datafile
where name = 'x'
select "ONLINE", online_status, error
from v$recover_file where file# = n

How to diagnose and recover corrupted datafile?

DBMS: Oracle v.9.2.0.1.0
OS: MS Server 2003 R2 SP2 x86
Problem: Database begin to stop every few minutes. I start to check and found that one and the largest of two datafiles is probably corrupted. Now I have no idea how to repair that datafile.
Firstly, I look into the alert.log and see that^
Mon Jul 29 11:02:03 2013

Dump file c:\oracle\admin\orcl\bdump\alert_orcl.log
So, I turned archivelog on and open database but it continue to stop when somebody calls to some DB objects.
Then, I check v$headers:
SQL> select file#, status, recover, fuzzy, tablespace_name, to_char(CHECKPOINT_CHANGE#), name from v$datafile_header;

For some reason, USERS in USERS_1.ORA is offline and marked as requiring recovery.
I tried to recover datafile, but get some errors:

That have looking creepy for me.
I tries to verify datafile:

Recovering lost datafile

My database 10.1 is running in noarchivelog mode and
and there was no rman backup
My datafile was lost and I want to restore a copy of the lost file but i have the following error when restarting the database
ORA-01203:, wrong incarnation of this file - wrong creation SCN
Any help?
Regards

In this case jus copy the datafile back to its original directory
startup mount
make the corrup[ted datafile offline
alter datafile '/.dbf' offline;
open the database
alter database open;
make the tablespace of the datafile offline
alter tablespace <tablespacename of the datafile> offline;
recover the resored datafile
recover datafile 'filename'
make the tablespace onlien
alter tablespace <tablespacename of the datafile> online;
This will work but
Let us wait from our experts

Recover datafile doubt

After did a switchover(DataGuard), on my current primary database I did a level 0 backup RMAN and it did not end due to an error with an datafile that needs recover, specifically the datafile 2 (sysaux tablespace). The last level 0 backup I have is 9 days ago. The first thing I do was restore the datafile and try to recover it.
RMAN> run{sql 'alter database datafile 2 offline'; restore datafile 2; recover datafile 2;}
The second step (recover) show me the following error:
unable to find archived log

RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 1 and starting SCN of 1757
I appreciate any help, thank you.

Dear user12100209,
Please see the error message;
RMAN-06054: media recovery requesting unknown archived log for thread string with sequence string and starting SCN of string
Cause: Media recovery is requesting a log whose existence is not recorded in the recovery catalog or target database control file.
Action: If a copy of the log is available, then add it to the recovery catalog and/or control file via a CATALOG command and then retry the RECOVER command.
If not, then a point-in-time recovery up to the missing log is the only alternative and database can be opened using ALTER DATABASE OPEN RESETLOGS command.So what i am thinking is that is happening because of a missing archivelog metadata(information) in the standby controlfile.
Below link may give you a general information;

Hope That Helps.

Restore & Recover SYSAUX datafile while DB up

Hi,
Due to data block corruption of SYSAUX, need to keep it offline then recover and make it online.
sql 'alter database datafile 2 offline';
restore datafile 2;
recover datafile 2;
sql 'alter database datafile 2 online';
Is it possible to do this operation while Database is up? or we need to keep it down?

Why you don't perform Block Media Recovery on the corrupted data blocks using RMAN?
In the following example I show how you can recover corrupted data block in the SYSAUX tablespace. However, as you use Oracle 11g, you will use the following syntax:
RECOVER DATAFILE datafile_no BLOCK block)no Here's the example:
SQL> create user test identified by test;
User created.
SQL> grant dba to test;
Grant succeeded.
SQL> conn test/test
Connected.
SQL> create table tbl_test (name varchar2(10)) tablespace sysaux;
Table created.
SQL> insert into tbl_test values('test');
1 row created.
SQL> commit;
Commit complete.
SQL> SELECT header_block FROM dba_segments WHERE segment_name='TBL_TEST';
HEADER_BLOCK

SQL> select tablespace_name from dba_segments where segment_name='TBL_TEST';

Creating a new controlfile with datafiles in RMAN backup

Hi,
i am using oracle 10g (10.2.0.1) in RHEL5 server. i am trying to restore a RMAN backup from one server to another new server with new db name. i have taken out the spfile from RMAN autobackup and created pfile from it and edited the pfile with new dbname and directory structure and started the db in nomount with the new pfile. Now i have restored the controfile from the RMAN autobackup tried to put the database in mount state. But it failed due to the below error
RMAN-03002: failure of alter db command at 11/05/2012 21:44:56
ORA-01103: database name 'ORADB' in control file is not 'DEVDB'
Hence i shutdown the database and started the db in nomount with new pfile and tried to create the controlfile with the new db name,but it failed as it is looking for the datafiles.
ORA-01503: CREATE CONTROLFILE failed
ORA-01565: error in identifying file
'/u01/app/oracle/oradata/DEVDB/datafile/o1_mf_system_80jq0kfw_.dbf'
ORA-27037: unable to obtain file status
Linux Error: 2: No such file or directory
Additional information: 3
All my datafiles reside in my RMAN backup. How to get the datafiles from RMAN backup in the above scenario??
Regards,
007

Hello;
The location and filename and DBIS will be different, but you need something like this :
$ORACLE_HOME/bin/rman << EOF
CONNECT TARGET /
STARTUP NOMOUNT;
SET DBID 3754763357; #DBID of PROD database
RUN
   ALLOCATE CHANNEL c1 DEVICE TYPE disk format '/u01/oradata/backups';
   RESTORE CONTROLFILE FROM '/u01/oradata/backups/sb_t790762003_s85_p1';
   ALTER DATABASE MOUNT;
   SET NEWNAME FOR DATAFILE 1 TO '/u01/app/oracle/oradata/CLONE/system01.dbf';
    SET NEWNAME FOR TEMPFILE 1 TO '/u01/app/oracle/oradata/CLONE/temp01.dbf';
   RESTORE DATABASE;
   SWITCH DATAFILE ALL;
   RECOVER DATABASE;
   release channel c1;
ALTER DATABASE OPEN RESETLOGS; So you need "SET NEWNAME" for all your files

6/ Try restore the deleted data file, it's not available in the backup ????? I do not understand this ? Really appreciate someone could explain this ?????

When you drop a datafile, the database instance updates controlfiles, redologs and SCN numbers. The datafile you have in your backup will no longer match the the rest of the database environment, so it cannot be restored without restoring the complete database prior to the time the datafile was dropped. Similarly you cannot mount or restore the datafile of a different database. The database does not maintain recovery information for a datafile that does not exist. If you loose the datafile, e.g. delete it from the filesystem, you can restore the datafile and recover the information using the existing controlfile and redologs. That is all normal and is not influenced by ASM.

NOARCHIVELOG - lost datafile

We have a situation here. We lost the datafile associated with UNDOTBS and we are in NOARCHIVELOG mode.
The option seems to be to use .....OFFLINE DROP and then drop the tablespace.
Accordingly, dropped the tablespace and attempting to open the database, the database is still looking for the datafile:
ORA-376 datafile xxxx cannot be read at this time.
how can I open the database....
My thought was to drop offline, open and then recreate the tablespace. It appears that I will not be needing any undo segments though.
Appreciate your help and thoughts.
BTW, this is DEV - therefore in NOARCHIVELOG mode.

Hello,
So, if I well understood you set the following parameters:
undo_management = AUTO
undo_tablespace = ''
And you still have the ORA-376 error.
So, I think, you may have an offline datafile.
May you execute the following statement ?
select status, enabled from v$datafile;You could check if you have an offline datafile or a datafile to RECOVER.
Hope it can help,
Best regards,
Jean-Valentin

Datafile not restored due to missing or corrupt data

Hi all,
I was asked to restore a RMAN backup which we got from another region, the rman backup contains controlfiles and datafiles as compressed backupset.
oracle version is 10.2.0.3.0
aix version 6
First, I have restored the control file using the below command:
run
+{+
allocate channel t1 type disk;
restore controlfile from '/oracle/app/prod/rman/cf_t799873684_s17_p1';
alter database mount;
+}+
Second, I have cataloged the backup piece:
catalog backuppiece '/oracle/app/prod/rman/df_t794754324_s12_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t793567544_s13_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t731097654_s14_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t792538698_s15_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t792183472_s16_p1';
catalog backuppiece '/oracle/app/prod/rman/cf_t799873684_s17_p1';
Third, used below command to restore:
+run {+
allocate channel t1 type disk;
allocate channel t2 type disk;
allocate channel t3 type disk;
allocate channel t4 type disk;
set newname for datafile 01 to '/oracle/app/oradata/dbprod/system01.dbf';
set newname for datafile 02 to '/oracle/app/oradata/dbprod/undotbs01.dbf';
set newname for datafile 03 to '/oracle/app/oradata/dbprod/sysaux01.dbf';
set newname for datafile 04 to '/oracle/app/oradata/dbprod/users01.dbf';
set newname for datafile 06 to '/oracle/app/oradata/dbprod/datafile005.dbf';
set newname for datafile 07 to '/oracle/app/oradata/dbprod/datafile006.dbf';
set newname for datafile 08 to '/oracle/app/oradata/dbprod/datafile007.dbf';
set newname for datafile 09 to '/oracle/app/oradata/dbprod/datafile008.dbf';
set newname for datafile 10 to '/oracle/app/oradata/dbprod/datafile009.dbf';
set newname for datafile 11 to '/oracle/app/oradata/dbprod/datafile010.dbf';
set newname for datafile 14 to '/oracle/app/oradata/dbprod/datafile001.dbf';
set newname for datafile 15 to '/oracle/app/oradata/dbprod/datafile002.dbf';
set newname for datafile 16 to '/oracle/app/oradata/dbprod/datafile003.dbf';
set newname for datafile 17 to '/oracle/app/oradata/dbprod/datafile004.dbf';
set newname for datafile 18 to '/oracle/app/oradata/dbprod/indfile001.dbf';
set newname for datafile 19 to '/oracle/app/oradata/dbprod/indfile002.dbf';
set newname for datafile 20 to '/oracle/app/oradata/dbprod/indfile011.dbf';
restore database;
switch datafile all;
recover database;
+}+
But while restoring, I got error like below:
