Datafile recover status

Hi Guys,
I am running Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production on Solaris 9.
I have a datafile that is on recover status and I can't recover this database to a consistent state with other datafiles.
The reason being that one of my archivelog that is needed for recovery is corrupt.
What should I do to remedy this situation?
Thanks in advance,

Hi,
As archive is missing , db recovery can not be possible done beyond that archive creation time and need to do incomplete recovery and open db with reset logs.
how important is datafile ? if that particular file is not important and if can be kept offline then we can make it offline AND open db to access.
Only data from offline datafile will not be accessible for users.
BR,
Rajesh

What is the solution to put it online ?
Thank you.

As sysdba, issue the
RECOVER DATAFILE 'datafile path/name';
command. If recovery information contained at the redo log files is enough, it will be recovered, and you'll have to put it online by issuing the
ALTER TABLESPACE tablespacename ONLINE;
command.
If you are prompted for previous generated sequences, then information is no longer available at redo logs, so you'll have to get it from the archive log files (archive log mode is assumed).

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

Undo datafile recover

hi
In undo tablespace 3 datafiles are there one datafile damaged now wt is the statud of database.
how can i recover that corrupted file.

Hi.You say that your database running in archivelog mode then you can try *"alter database create datafile as"* if this statement does not any effect then you need drop this datafile and you can create new undo tablespace then switch this tablespace.Following example will help you.
1.Backup your database.
2.Delete from OS level this/corrupted datafile then

RMAN via OEM: Skipping days with incremental backups

Hello,
I've searched the forums and browsed much of the documentation on OTN but have not found the answer to my question. I am using RMAN (through Oracle Enterprise Manager) to schedule backups. I want to get full database backups on Fridays and incrementals Monday through Thursday. I would like to have the backups running at 11 PM each night. I have scheduled the full database backups to occur every Friday. The problem is I cannot schedule the incrementals to skip Fridays, Saturdays and Sundays. I don't want incrementals on Friday since the full database backup will be running. No transactions are occurring on Saturday or Sunday so there is no need to backup on those days either.
Thank you for any help,
Paul Lohr

You have had issues with FileID 74 earlier
[RMAN] problem with registering database
DATAFILE RECOVER STATUS
and now with FileID 75 ?
Bring in Oracle Support. Log an SR. Ask for ACS onsite. Don't use forums.oracle.com for such issues.

What should I do to make this datafile droped or at least make it online/offline? What I am worry is the database will be failed to restart because of this 'RECOVER' datafile.
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?
Thanks

Hi,
First of all you must Open a ticket with oracle Support and explore the options
You can use this note to fix it:
RECOVERING FROM A LOST DATAFILE IN A UNDO TABLESPACE [ID 1013221.6]
If you is Unable to Drop Undo tablespace Since Undo Segment is in Needs Recovery
You can Upload the following trace file while opening the ticket
SQL>Alter session set tracefile_identifier='corrupt';
SQL>Alter system dump undo header "<new of undo segment in recover status>";
Go to udump
ls -lrt *corrupt*
Upload this trace file
Also upload the alert log fileRegards,

Recover datafile

Hi All,
DB: 10g No Archive mode
OS: windows
I am unable to recover my datafile after renaming the same. Following are the steps that I have taken:
I have a old controlfile trace and the latest controlfile is lost. The old controlfile doesnt have the new datafile entry.So i am mounting the database with the old trace with resetlog option and then i will be renaming the unamed datafiles.
STARTUP MOUNTThen i create controlfile
ALTER DATABASE OPEN RESETLOGS;Now the newly added datafile is as below:

RAC instance, trying to recover UNDO datafile, RMAN gives RMAN-06054

Hello all,
This has been a troublesome instance..a quick bit of background. This was created awhile back by someone else, I inherited this 3 mode RAC clusterof instance1.
I'm exporting out of one database (10G) into this instance1 (11G). When I was about to start the import..I found this instance wouldn't start. Turned out no backup had been going on of this empty instance. I backed up the archive logs to tape to free up the FRA..and things fired up.
I began the import, and found a bunch of errors...basically tellling me that I couldn't access one of the undo tablespaces...datafile problems.
I went to look and saw:

This is all on ASM, and am a bit of a newb with that. I bascially have no data I'm worried about losing, I just need to get everything 'on the air' so I can import successfully, and let users on this instance. I've set up the backups in GRID now....so, it will be backed up on the future, but what is the quickest, most efficient way to get this UNDO tablespace datafile recovered?
Thank you,
cayenne

Hemant K ChitaleOops...meant to have start and set until both to "1"
However, I see what you mean. It seems I cannot find the file on tape.
Since the RAC instance hasn't yet had any data put into it, I'm thinking it might be best to just blow it away, and recreate everything.
Trouble is, I'm a bit new at RAC and ASM. I was thinking the best route might be to use DBCA to remove the database...? Would this not take care of removing all the datafiles from all the ASM instances on the RAC..as well as all the other directories, etc on all 3x nodes?
I've already used the dbca to create templates of this instance, so recreation shouldn't be too difficult (although it will be my first RAC creation)...
Thank you in advance for the advice so far,

Recover datafile problem

Hi, I am using Oracle 7.3.4 on NT 4.
I am having problem with one of my rollback segments call HISTORY which contain two datafiles in e:\rollback\history.ora and f:\rollback\history.ora
This rollback segment was used for transfer old data to HISTORY datafile in
f:\HISTORY\HISTORY.ora
(the sql look like this -
set transaction use rollback segment history;
insert into history.bk_tableA
where ..... )
Recently the HISTORY rollback was droped by mistake. Since then I lost access to history tables( in HISTORY datafile). When I open the storage manager
it shows these 3 files are in recover status.
What is the relationship between the History rollback seqment and History datafile?
The list below were the errors I got when trying to recover a datafile
First attemp:
SVRMGR>

ORA-00334: archived log: 'D:\ORANT\RDBMS73\ORCL25290.001'
I try auto, and even the suggested log file orcl25290.001 and still could not recover the datafile. It seems the recover program
cannot find the specific sequence # in the log file! Any suggestion?
Second attemp:
I try the incomplete, change base recovery -
SVRMGR>recover until chang 525082215
it shows Media recovery complete. Then, I open the database with
'alter database open noresetlogs'
But I still cannot access to that data file.
svrmgr>select count(*) from history.bk_sn_err;
count(*)
ora-00376: file 5 cannot be read at this time
ora-01110: data file 5: 'f:\history\history.ora'
From the storage manager the file is still in recover status.
Does the file been recovered at all?
Is it possible that I could drop the damaged
rollback segment and recreate a new one.
Should I be able to gain access to the f:\history\HISTORY.ora datafile?

Hi Micheal,
when you said you had dropped the history, did you drop the rollback segment or did you delete the history.ora file from the NT or did you drop the file from Oracle by doing an
alter database adatfile '...history...'offline drop?
also is your database running in archivelog mode?
depending on the above, you will have to use different methods to recover.
from the error messages you seem to be running with no archivelog mode so you have to offline drop the datafile.
If you do an offline drop on the datafile, then you will have to drop tha tablespace and recreate it.
Thanks,
Mandar

I am not sure how did this happen files do not spontaneously go missing.
but the file is present the OS level.error message would indicate that Oracle disagrees with your assessment.

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

Hi,
First of all you must Open a ticket with oracle Support and explore the options
You can use this note to fix it:
RECOVERING FROM A LOST DATAFILE IN A UNDO TABLESPACE [ID 1013221.6]
If you is Unable to Drop Undo tablespace Since Undo Segment is in Needs Recovery
You can Upload the following trace file while opening the ticket
SQL>Alter session set tracefile_identifier='corrupt';
SQL>Alter system dump undo header "<new of undo segment in recover status>";
Go to udump
ls -lrt *corrupt*
Upload this trace file
Also upload the alert log fileRegards,
