Any One pls Help me...

Seems that your DB is running in NOARCHIVELOG mode : try using "offline drop" :

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;

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.

Recover database with corrupt datafile

I have an Oracle 9.2.0.6.0 database which has crashed due to disk failure & there is no backup. on the disk that failed there is one rollback datafile so I was hoping to be able to just drop this datafile & the related tablespace & recreate on disk that is OK.
I found the following instructions in a thread on this forum & managed the offline drop of the datafile & the alter database open. However when I tried to drop the rollback tablespace it couldn't find what I though the tablespace was. Now when I try & do anything with the DB is failed with the error -
Error 376 happened during db open, shutting down database
USER: terminating instance due to error 376
Instance terminated by USER, pid = 47050
ORA-1092 signalled during: ALTER DATABASE OPEN...
the instructions I was following were :-
Database was NOT cleanly shut down
I.e. Datafile was accidentally dropped using operating system command, when the database was not cleanly shutdown using SHUTDOWN ABORT COMMAND.
* Check the alert.log file for this instance.
* Comment out the ROLLBACK_SEGMENTS parameter and add the following line: corruptedrollback_segments = ( ,...., ) i.e., the above list should contain all the rollbacks originally listed in the ROLLBACK_SEGMENTS parameter.
* Mount the database in restricted mode. STARTUP RESTRICT MOUNT
* Offline drop the lost datafile.
ALTER DATABASE DATAFILE OFFLINE DROP;
* Open the database.
ALTER DATABASE OPEN.
* Drop the rollback tablespace to which the datafile belonged.
* Recreate the rollback tablespace with all its rollback segments. Remember to bring the rollbacks online after you create them.
* Make the database available to all users.
* ALTER SYSTEM DISABLE RESTRICTED SESSION;
You should be able to see your database back at this step.
Any ideas how to indentify the tablespace that I need to drop & how to get the database into a state that will let me attempt this?

Taking the datafile offline when the database is in NOARCHIVELOG mode

My question is when the database is in No Archive log mode i'm not able to take the datafile offline.
When i tried in my computer i have noticed fallowing.
case1:
SYS>alter database datafile 5 offline;
ERROR at line1;
ORA-01145:offline immediate disallowed unless media recovery enabled.
case 2:
SYS>alter database datafile 5 offline immediate;
ERROR at line 1;
ORA-00933:SQL command not properly ended
case3:
I have tried the command alter database datafile 6 offline drop; (in NOARCHIVELOG mode) and it is showing the same effect as alter database datafile 6 offline; ( in ARCHIVELOG mode).
*In the NOARCHIVELOG mode are we really dropping the datafile to take the datafile offline? Will you please tell me the effect of keyword drop.

You've marked your question answered - was that a mistake?
The answer is that you cannot directly take a datafile offline in noarchivelog mode. You must take the tablespace offline:
Hmm, are you certain about that? Perhaps I'm missing something.

No Online backups due to datafiles offline than I canu0092t recover. How...?

Hi gurus!!!
I got into a problem with some datafiles.
We have MySAP in a BD oracle 9.2.0.6
I used Oracle Entreprise Manager Console to generate two datafiles in the tablespace PSAPPRDUSR,
but I generated them in another tablesapce (PSAPPRD) with a name of file,
size and location very different from those that there uses the tablespace PSAPPRD.
So... I put them offline later to erase them later!!!
The datafiles contains no data.
Later, in the night backup:
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2 is RECOVER
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2a is RECOVER
 BR0301E SQL error -1128 at location BrTspAlter-3
 ORA-01128: cannot start online backup - file 31 is offline
 ORA-01110: data file 31: '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
 BR0280I BRBACKUP time stamp: 2007-04-20 03.01.21
 BR0316E 'Alter tablespace PSAPPRD begin backup' failed
 BR0056I End of database backup: bdvbtndh.ant 2007-04-20 03.01.21

And now... I neither can erase them nor can put online again.
To erase them I used:
SQL> ALTER DATABASE DATAFILE '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2' OFFLINE DROP;
Database altered.
SQL> commit;
But they continue there, do not resign.
To put them online:
SQL> alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2';
alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
ERROR at line 1:

ORA-00280: change 31203204 for thread 1 is in sequence #2574
SQL>
But we have continued working and I don't want to lose any data.
HEEEELP!!!!
What I can do to recover the datafiles and to continue with my daily Online backups?
The BD is in production and I do not have long time to fix it, only a few hours on Saturdays night.

Hi,
alter database datafile offline drop;
This command is not meant to drop a datafile. It is meant to offline the datafile with the intention of dropping the tablespace.
For a tablespace comprising multiple datafiles you can only drop a datafile by dropping the entire tablespace, this will work even you have one datafile.
If you have 10gr2, it's finally possible to drop a datafile as long as
it's not the only datafile within the tablespace, and
the tablespace is only and in read-write status.
So since you are on 9i your situation in summary:
If you have more than one datafile in the tablespace and you wish to keep the objects that reside in the other datafile(s) which are part of this tablespace, then you must export all the objects inside the tablespace.
1. Gather information on the current datafiles within the tablespace by running some query to remember the t/s, segment, and datafile info.
2. Export all the objects that you wish to keep.
3. Once the export is done, issue the DROP TABLESPACE <tablespace name> INCLUDING CONTENTS.
4. Delete the datafiles belonging to this tablespace using the operating system.
5. Recreate the tablespace with the datafile(s) desired, then import the objects into that tablespace.
Hope this helps and good luck,
George

Problem in recovering a database on another machine

Dear All,
I need your help in restoring and recovering a database on another machine. I don't have access to old machine to get logfile or archivelogs. I have taken full backup using RMAN. I have restored the database using rman sucessfully and trying to recover the database. RMAN have't restored the logfile. Database version is 8.1.7.4, OS is Solaris 8. In recovery, its showing the problem in rbs file. I'm showing all command and error. Just give me any idea that how to recover it sucessfully.

Why its asking for archive file which generated on 19th, when I'm trying to recover until 16th only.
Regards
Rakesh

Hi.
What is the size of the redo logs in the database. With a small amount of transactions, there might be redo in this particular archived file from two days back. The timestamp of the archivelogfiles does not indicate that all redo in the file is from this day. It might have changes several days back if no logswitch occured inbetween.
So, if I were you, I would provide all archivelogs required to get the datafiles consistent.
As a matter of fact, if archived redo is in the following folder :
/u07/oraexp/PROD/arch/
I would use recover database until time and press return for all archived logs svrmgrl comes up with.
I assume that the database was closed normally prior to taking the offline backup.
Good luck.

hi
I myself have found the solution , when I recover the standby database
it do recovery but at the end of recovery it raise the error(RMAN-06054: media recovery requesting unknown log: thread 1
seq 118 lowscn 1392700) but if I begain redo apply before open the database
and I wait till all redo apply process start and communication between the
standby database and the primary database start, then I can
open the standby database and no error will raise
but if befor restarting redo apply I open the database I'll recieve the
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/sari/system01.dbf' error
thanks

Recover database to new server problem

Hi all,
I'm running a production 10.2.0.4 DB in archivelog mode on Solaris 10.8. I used RMAN with a recovery catalog to execute the stored script:
run{sql 'alter system archive log current';
backup incremental level 0
database archivelog all delete input;}
I copied the rman files and spfile to a test server with the same directory structres. No Problem.
Using "rman target /" I started the database in nomount and restored the controlfile from backup and mounted the database. No Problem.
Still within the RMAN session, I restored the 1TB worth of datafiles. The restore completed, no problem.
I then issued the command, "recover database;" PROBLEM, RMAN said datafile1 "System.dbf" needs more recovery to be in a consistent state.
WHY? I issued the commands, "alter system archive log current;" and "archivelog all delete input" in my script.
Why does it need the next archivelog to be consistent?
I was under the impression that all I need to recover a database with rman was the output files from RMAN.
I copied the next archivelog over and in SQLPLUS as SYS I issued the command, " recover database using backup controlfile until cancel;"
I canceled the recovery when it asked for the next archivelog and opened database reset logs.
If I didn't have access to the next archive log how would I solve this problem?

Your BACKUP should be executed as BACKUP DATABASE PLUS ARCHIVELOG. The "PLUS ARCHIVELOG" causes Oracle to issue an ALTER SYSTEM SWITCH LOGFILE at the end of the database backup so that the ArchiveLog generated gets picked up by the subsequent Backup of the ArchiveLog as well.
Your first RECOVER DATABASE command was attempting a Complete recovery. Had you specified an UNTIL clause, Oracle would know that you wanted an Incomplete recovery upto the last available archivelog. Your second RECOVER DATABASE with the UNTIL CANCEL was an Incomplete Recovery.

Why we cannot take hot backup if database is in noarchive log mode

Hi,
I am aware that if database is in noarchive log mode, we cannot take hot backups and only cold backup is possible.
I would like to know the technical reason behind this restriction?
Thank You
Sarayu

Hot backups are fuzzy backups, inconsistent, in other words, since something is always happening in the database. When you recover, you restore data files and then apply redo to make the transactions consistent. You can do a complete recovery or recover to a point in time. So where does the redo come from? That's what we call archiving redo logs. When the online redo gets full, it gets archived.
In the case of an instance crash, the redo is there in the online redo logs, so Oracle can recover automatically. Anything beyond that, having to do with storage media, is a media recovery, and requires those archived logs. So unless you have some other way to get your data back, always run in archivelog mode.
It is really important to understand the concepts. Please read the docs.
http://docs.oracle.com/cd/E11882_01/server.112/e25789/cncptdba.htm#CNCPT031
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmintro.htm#i1005488
It may be worth your while to get a third party backup and recovery book too.

Problems with DUPLICATE DATABASE when datafile was added after full backup

Hi,
I'm facing a problem when performing database duplication with the RMAN duplicate database command on a 10g database. If I preform the duplication from a full backup that is missing a datafile which was added to the database after the full backup, I get the following error message:
Starting restore at 10-10-2009 18:00:38
released channel: t1
released channel: t2
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-03002: failure of Duplicate Db command at 10/10/2009 18:00:39
RMAN-03015: error occurred in stored script Memory Script
RMAN-06026: some targets not found - aborting restore
RMAN-06100: no channel to restore a backup or copy of datafile 43The redo log which was CURRENTat the time of the datafile's 43 creation is also available in the backups. It seems like RMAN can't use the information from the archived redo logs to reconstruct the contents of datafile 43. I suppose that because the failure is reported already in the RESTORE and not in the RECOVER phase, so the archived redo logs aren't even accessed yet. I get the same message even if I make a separate backup of datafile 43 (so a backup that is not in the same backupset as the backup of all other datafiles).
From the script the duplicate command produces, I guess that RMAN reads the contents of the source database's controlfile and tries to get a backup which contains all the datafiles to restore them on the auxiliary database - if such a backup is not found, it fails.
Of course if I try to perform a restore/recover of the source database it works without problems:
RMAN> restore database;
Starting restore at 13.10.09
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=156 devtype=DISK
creating datafile fno=43 name=F:\ORA10\ORADATA\SOVDEV\SOMEDATAFILE01.DBF
channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
restoring datafile 00001 to F:\ORA10\ORADATA\SOVDEV\SYSTEM01.DBF
.....The datafile 43 is recreated and then redo is applied over.
So, does anyone know if duplicate database can't use archived redo logs to recreate the contents of a datafile as a normal restore/recover does? If it's so, then it means it's necessary to perform a full database backup before every run of duplicate database if a datafile was added after such a backup.
Thanks in advance for any answers.
Regards,
Jure

Hi Jure,
I have hit exactly the same problem during duplication.
Because we backup the archive logs every 6 hours with rman I added an extra run block to this script.
run
backup incremental level 0
format 'bk_%d_%s_%p_%t'
filesperset 4
database not backed up;
(I also than hit a bug in the catalog which was solved by patching up the catalog dbs from 11.1.0.6 to 11.1.0.7.)
This will narrow down the datafile not being part of any rman backup to 6 hours while skipping datafiles for which a backup already exists.

Tycho

My ipad front camera doesn't working,cannot take a picture this moment,how to fix this problem?

My ipad front camera doesn't working,cannot take a picture this moment,how to fix this problem?

Try closing the Camera app via the taskbar and see if it works when you re-open the app : from the home screen (i.e. not with the Camera app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Camera app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Problem in recovering the database!!!

Hi All,
I created a new database and wanted to restore the backup of another database into it, I created the required tablespaces and started restore of backup from RMAN using
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=orcl,OB2BARLIST=DAILY_HISDBS01_ORACLE-DB_ONLINE_5W,OB2BARHOSTNAME=hisdbs01.kfmc.med)';
restore controlfile from 'c-1179279249-20090511-02';
alter database mount;
release channel 'dev_0';
The controlfile got restored successfully, then I tried to restore & recover the database
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=central,OB2BARLIST=DAILY_HISDBS01_ORACLE-DB_ONLINE_5W,OB2BARHOSTNAME=hisdbs01.kfmc.med)';
restore database;
recover database;
release channel 'dev_0';
The restore was successful, but when I tried to open the database with resetlogs option
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:

The recovery process is looking for */arch/archivelog/1_8493_651861624.dbf* this archivelog, but this archivelog file is not present at that location, the restore process should have restored all the archivelogs as well, actually no archivelogs got restored, how can I recover the database without archivelog logs? it is not possible at all.
PLEASE tell me how can I make the database work?

Thanks Hemant !!!
I restored the archivelogs using the script below
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=central,OB2BARLIST=DAILY_HISDBS01_ORACLE-DB_ONLINE_5W,OB2BARHOSTNAME=hisdbs01.kfmc.med)';
restore ARCHIVELOG FROM TIME 'SYSDATE-5' UNTIL TIME 'SYSDATE';
release channel 'dev_0';
then recoverd the database and applied the requested archivelog file and opened the database with resetlogs, it is now successfully recovered upto the point I wanted it to be.

Recover Database vrs Recover Tablespace & Datafile

Traditionally when I have been recovering a database either to point of failure or point in time I have issued
RECOVER DATABASE AUTO;
(or I have specified the point in time I wish to recover to ).
I see now in 11gR2 there is also a RECOVER TABLESPACE and a RECOVER DATAFILE command
Why would you use those instead of the RECOVER DATABASE ? You would have to be pretty sure it is only that tablespace or data file you wanted to apply archive logs to, otherwise would your recovery not risk putting the contents of that tablespace or datafile out of logical sync with the data in other tablespaces ( eg potentially viloating referential integrity etc ) ?
I am presuming these commands also only apply the contents of archive logs that effect the specified tablespace or datafile ?
thanks,
Jim

If I issue a RECOVER TABLESPACE or RECOVER DATAFILE for a Tablespace or Datafile that is current and does not need recovery, Oracle does nothing to the Tablespace / Datafile. It won't be out of logical sync with the rest of the database.
>>>
Can you recover the data file or the tablespace to a point in time before the current time ? If that is the case then surely it is possible that the recovered tablespace could have a table in it that has referential integrity to another table in a different ( unrecovered ) tablespace and that the referential integrity could then be compromised ?

Lost seq of redo log due to corruption and cannot recover database.

Hi!
This db I am working on is a test database running 10.2.0.3 on OEL5. Unfortunately due to some human error, we lost the redo log sequence 1_28_xxxxxx.redo. As this was a non-critical db, we didn't plan any backups for the db... and now whenever I try to open the db I get the error:

Is there a way to open the database!?
