Recover the database to a point

hi experts,
In my database one important table has been uppdated with wrong data. I need to recover the old data.
How can I do this. ????
Pls can somebody explain ???

Hi,
Just a comment ....
One option, but in your case the worse option will perform an incomplete recovery based on time.
Example:
It is 12:00 AM and the EMP table was wrong updated at 11:45 AM
Then you can:
1) shutdown the database and make a backup
2) restore all datafiles from most recent backup
3) mount the database
4) recover the database like below:
SQL> recover database until time '2007-02-13:11:44:00'
5) synchronize the datafile with control files and redo log files like below:
SQL> alter database open resetlogs
6) Make a backup of your database
Disadvantage of this method
After the recovery process, all information after 11:44 AM will must be informed again ...
Cheers

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.

How to recover the database when some of the archive log file get deleted.

I am facing a problem with Oracle database, which is related to archivelogs.
Our development database is running in archivelog mode, but we don't have backups scheduled and have no recovery catalog.
When the database was in running condition, disk got full, so some archivelogs were deleted manually.
After this they restarted the DB, and now DB is not coming up. Errors are as follows:

Hi,
Archive log files are the copies of redolog files.As redo log files are circularly overwritten,oracle generates archive log file of the corresponding redo logfiles being overwritten.So if you have a backup that dates back to 10 am in the morning and if your database creashed at 3 pm,you cannot use the redo log files alone as they have incomplete information.To completely recover the database upto 3 pm,you need archive log files generated between 10 am to 3 pm. In your case since you are missing one archive log file,you cannot perform complete recovery and hence would suffer data loss.

Redo log files are deleted, how to recover the database

Hi All,
I removed the redo01.log, redo02.log and redo03.log files of our Oracle database. And it caused the db to fail. Is there any way I can recover the database and startup database in normal mode? I do not need it to have all the latest data restored, I will be happy to just start the db and get going.
database is in arcive log mode.
Thanks

Hello,
You may try this if the database is mounted:
recover database until cancel;
cancel
alter database open resetlogs;Hope it can help.
Best regards,

What should be done to recover the database?

Hi all,
While backing up the database, the computer running Oracle loses power. After restarting the
computer what should be done to recover the database?
Please help me..
Thank you all for your cooperate.

Thanks mr. Eduardo Rezende.
I'm an Arab student and now I study database administrator course. This question asked by my teacher. So, if anyone can answer this question and some other questions please help me.

Can I recover the database to the current time using a backup control file?

Can I recover the database to the current time using a backup control file? How far can I recover this database?
I have an Oracle 10g(10.2.3) database on RHEL4.3 system.
I have lost all the current control files and all the online redo logs, archived redo logs and all other files are OK.
Now I have to recovery this database using a backup control file.
Can I recover the database without any data lost？

If
a) it was a Shutdown Abort or an Instance Crash (i.e. backgrounds died on detecting loss of redo logs),
b) redo logs are lost
c) data files are intact
You'd have to
a) Restore datafiles
b) Do an Incomplete Recovery to the last available ArchiveLog

EnvironmentFailureException thrown while recovering the database!

While recovering the database, an EnvironmentFailureException with LOG_FILE_NOT_FOUND was thrown. The exception was thrown after some data was recovered, and the left data can not be recovered because of the EnvironmentFailureException.
I upgraded the je to 4.1.7, but the data still can not be recovered!

To Recover The Database Using a New Version of Datafile

Please give me the solution immediately
My one of the datafile is new and it is very important. It contains many data. I have a backup. I copy all the old files exept the new one. How i attatch the new datafile to the old database files. Now it sees the new file does not match with the old datafile and controlfile. It shows the message
THE CONTROLFILE VERSION IS OLDER THAN THE NEW DATAFILE VERSION.
our database version is 8.0
How i recover

Hi;
Please Give a Solution for the following problem.
First I shutdown the databae.
Copy all the redolog,control file and Datafile except one.
One datafile i miss at the time of copy.
Then I start the database and do some transactions.
At that time my system tablespace has been corrupted.
So i copy the old backup and overwrite with the actul file.
So one file backup is not there, that i forgot to take.
At the time of opening the database it shows that datafile version is higher than the controlfile.
Now what i did is came to mount stage and type the following command.
ALTER DATABASE DATAFILE <FILENAME> OFFLINE DROP;
After that i open the database.
Now the problem is that missing file contain very important data.
Is it possible to recover the data?
Please give me an immediate solution.

I want to recover the Deleted Database

We have an accidentally deleted the database, there is no recent backup file for past 5 months. I want to recover the deleted database. Please give an idea/Suggestions to recover the database. And also we tried some third party tools like kernal,SQL Recovery,Steller
Phenix and those tools are repairing the corrupted database,but it could not find the deleted ".mdf" file for the database. Please give a best steps/suggestions to recover the database.

Is there any option to recover the ".mdf" and ".ldf" files of deleted database by using file recovery softwares
You can try some of the Windows "undelete" tools, but there is no guarantee it will work or that the database files will be in a valid state afterwards.
The only reliable way is to restore a backup ... which you don't have.

NEED TO RECOVER A DATABASE USING RMAN with CONTROL FILE AND NO RMAN CATALOG, DISK FAILURE..

Hello All,
The disk failure caused our production data on the disk to be resotred with the backup data available and recovered through RMAN with cotrolfile , and no catalog DB is configured.
I had the restored the spfile and control file then recovered the database,
startup nomount;
RESTORE SPFILE FROM ' path ' ;
Shutdown immediate;
startup nomount
Restore controfile from autobackup;
restore database;
[AT POINT , A MESSAGE PROMPTED LIKE " failur of restored command - some targets not found" (thinking may be few archives are not found, i proceeded to incomeplete recovery of DB) ]
recover database;
Finished reocvery .
Now in the Grid control i see that 60 blocks of a particular datafile are corrupted and needs recovery. Do i need to get the data file resotred again and recover it or any simple way to recover this data file
When i perform the block recovery , it says recovery failed and when i run the data file recovery it succeeds. Please provide you inputs to recover the database as it is production BI database and pretty critical to our client.
Thanks for your valuable time in advance.
Regards,
Ran G.

These is a common problem if the object are created due to NOLOGGIN option. If you check most of the object which are facing block corruption is indexes .
Use the below query to check the objects :
It will map each block from v$database_block_corruption to either a segment or if the block is free.
$ sqlplus / as sysdba
set pagesize 2000
set linesize 250
SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file#
, greatest(e.block_id, c.block#) corr_start_block#
, least(e.block_id+e.blocks-1, c.block#+c.blocks-1) corr_end_block#
, least(e.block_id+e.blocks-1, c.block#+c.blocks-1)
- greatest(e.block_id, c.block#) + 1 blocks_corrupted
, null description

Restoring only the tablespace from the database

How do we restore only a 'tablespace' from a Terabyte database without restoring the entire database.
ie... if a particular tablespace has been dropped from the database and we have the backup available for the database.
So, how do we go about it for restoring only that tablespace.

If you have a RMAN backup before dropping the tablespace then we can restore the tablespace by below method
It is a tablespace point in time recovery ,here we need to create a auxillary DB.
Recover a table/tablespace from Rman backup on same server:
===============================================
Here we have to create the auxillary database.
1.u should have valid backup of the database before dropping the tablespace.
2.create the password file of target database.
orapwd file=$ORACLE_HOME\dbs\PWDORCL2.ORA password=oracle
3.Take backup of the control file to trace for creating the new control file for new
auxillary database/
SQL> alter database backup controlfile to trace;
sample control file:
STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "aux1" RESETLOGS FORCE LOGGING ARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 454
LOGFILE
GROUP 1 'D:\ORACLE\PRODUCT\10.1.0\ORADATA\aux1\REDO01.LOG' SIZE 10M,//make sure here to change the location of of redo
GROUP 2 'D:\ORACLE\PRODUCT\10.1.0\ORADATA\aux1\REDO02.LOG' SIZE 10M, logs to new location or change the location name before
GROUP 3 'D:\ORACLE\PRODUCT\10.1.0\ORADATA\aux1\REDO03.LOG' SIZE 10M //starating the database at the end.
-- STANDBY LOGFILE
DATAFILE
'D:\ORACLE\PRODUCT\10.1.0\ORADATA\prafulla\SYSTEM01.DBF',
'D:\ORACLE\PRODUCT\10.1.0\ORADATA\prafulla\UNDOTBS01.DBF',
'D:\ORACLE\PRODUCT\10.1.0\ORADATA\prafulla\SYSAUX01.DBF',
'D:\ORACLE\PRODUCT\10.1.0\ORADATA\prafulla\USERS01.DBF',
'D:\ORACLE\PRODUCT\10.1.0\ORADATA\prafulla\USERS02.DBF'
CHARACTER SET WE8MSWIN1252
4.create the password file of auxillary database.
orapwd file=$ORACLE_HOME\dbs\PWDORCL2.ORA password=oracle
5.create the control file
sqlplus "/as sysdba"
SQL>@create.sql
6 catalog all the backuppiece to the newly created database;
catalog backuppiece 'D:\oracle\product\10.1.0\LOG_707656915_50P1';
7.We have to restore system,sysaux,undo and the tablespace which was dropped
run
set newname for datafile 1 to 'D:\oracle\product\10.1.0\oradata\aux1\system01.dbf';
set newname for datafile 2 to 'D:\oracle\product\10.1.0\oradata\aux1\undotbs01.dbf';
set newname for datafile 5 to 'D:\oracle\product\10.1.0\oradata\aux1\users02.dbf';
set newname for datafile 3 to 'D:\oracle\product\10.1.0\oradata\aux1\sysaux01.dbf';
set newname for datafile 4 to 'D:\oracle\product\10.1.0\oradata\aux1\users01.dbf';
restore tablespace SYSTEM;
restore tablespace UNDOTBS1;
restore tablespace users;
restore tablespace sysaux;
switch datafile all;
8.Take the other tablespace offline
sqlplus>alter tablespace tablespace_name offline drop;
9.recover the database prior to the time when tha table/tablespace was dropped.
RMAN> run{
2> set until time "to_date('07-01-2010 14:00:00','dd-mm-yyyy hh24:mi:ss')";
3> recover database;
4> }
10.open the database in resetlog mode.
take a transpotable tablespace backup of that tablespace and import it on the database where you dropped it.

How can i recover my database after losing system data file.

hi everyone,
how can i recover my database in the following scenario.
1. offline complete backup taken 2 days ago. database was in archive mode.

now i don't have any archive file. is there any chance to recover the database ?If no archive log files are available you can't recover the datafile.You need to have all the archives from the time of offline backup was taken till the system datafile is lost.

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.

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.

How to recovery the database from a complete backup

I have a 10.2.0.3 database with archive log enabled.
I do a cold backup of database every Sunday night.
I shutdown the database, copy all the database files, control files and redo logs to a backup disk.
Then the database started and running again.
I am trying to test my backup and make sure I can recovery the database to the most current stage using the Sunday backup and the archive logs.
for example: use the backup from 4/01/2012, recover the database to today 4/04/2012 9:00am.
What's the steps of doing this?
I tried to copy all the Sunday backup files to the correct location, start the database, the database is started successfully. However, I don't know how to apply the logs from since the Sunday backup upto now.
Thanks a lot!

hi,
rman is your friend to do backups, restores and recovers of database.
to do a full recover of database, for example to do a test on your current test database (no in crash):
rman time:
startup nomount;
restore controlfile;
alter database mount;
sql now
select archivelog_change#-1 from v$database;
then go back to rman and do the following :
RMAN> run{
2> set until scn xxxxxx;
3> restore database;
4> recover database;
5> alter database open resetlogs;
6> }
**where xxxxx is the result of your sql query
HTH
--edit:
forgot to told that You will need to set your ORACLE_HOME and ORACLE_SID env variables
