Recover database using cold backup

Hi All,
One of the table is delete by one of our DBA from PROD accidentally. We have a cold backup on one day before.
Now we are trying to restore it from the cold backup. PROD DB is in archivelog and all the archive is in tact.
The table got truncated today at 8 PM. Can we apply the database till 8 PM so that we can restore the truncated table using cold backup.
Please find the below steps which we are using to restore.
creating controlfile
starting the db in mount state
recover database;
Will it ask for latest archive log when we try to recover it.
ENV details -
DB - 11.2.0.1
Please suggest.
Thanks

Hi,
If you have doubts about the procedure to use to restore a backup to a point in time, then please take a look at the documentation first: Performing Flashback and Database Point-in-Time Recovery - 11g Release 2 (11.2)
After you specify the time when the recovery must end (UNTIL clause in rman), then the RECOVER command will try to use the archivelogs needed.
Before starting with this PITR operation, you should check if your database has flashback active, because it will be much easier to recover using it.
This is also explained on the same document linked above.
Regards.
Nelson

1. Kill current instance with SHUTDOWN ABORT.
2. Copy all control files and data files from your cold backup to original destination.
3. Make sure all archived redo logs from 01-JAN to 04-JAN are available in the database archive destination (LOG_ARCHIVE_DEST or LOG_ARCHIVE_DEST_x).
4. Run as SYSDBA:
startup mount
recover database using backup controlfile until cancel;When prompted for something like

Build standby database using cold backup on a different file system & host

Hi gurus,
The database version is 11.2.0.3. OS is HP UX Itanium 11.31
I am building a standby database using cold backup of primary. The primary mount points are (/p003/oracle, /p004/oracle) on HOST1 and the standby file system on HOST2 are (/s003/oracle,/s004/oracle). I am not using Data Guard to apply logs as we have a script that mounts the log location periodically to standby server and apply the logs to make it current. I am using cold backup as the database is small like 200G and can be taken down. Could someone help me with the steps to build standby using cold backup for a different file location in standby ?? My concern is I can copy the data files from /p003 to /s003. How will I build the controlfile ?
If it was same File system on both HOST 1 and HOST2 I can copy the cold backup to the standby server, build a standby control file on primary and copy and replace the standby control file and everything was set.
Thanks

Recover datafile using cold backup in archivelog mode

Hi,
I have lost one of my datafiles i.e New.dbf from the disk. I have full database cold backup of last sunday. Also I have the archives. Is it possible to restore and recover only the lost datafile? Please help.

If you used RMAN to create the backup, then use RMAN again to restore that one datafile alone (RESTORE DATAFILE n) and then recover it (RECOVER DATAFILE n).
If you didn't use RMAN but you are sure that the backup was a COLD Backup, manually restore the datafile and then issue a RECOVER DATAFILE n from the SQLPlus command.
In either case you must ensure that the datafile is OFFLINE before you restore the file -- or take it OFFLINE with ALTER DATABASE DATAFILE n OFFLINE IMMEDIATE before doing the restore.
After the RECOVER is completed, you must bring it ONLINE with an ALTER DATABASE DATAFILE n ONLINE

Database cloning using cold backup

Hello Guys,
I am doing cloning of a database from cold backup for testing, actully one datafile has been croupted, so my issue is that, can i exclude tht datafile from controlfile when creating the controlfile and is that poosible that controlfile will created sucessfully and database will open sucessfully.
Please reply.
Thanks

@asif, @ckpt
With humble, how all you know that corrupted datafile is not belonging to system and undo tablespace? If this case, then do you think we can restore that corrupted cold-backup ? Sorry, but this is not the way to just start providing help without asking OP :
1.Current Oracle Version ?
2.Where he want to restore i.e. restoring platform info Oracle version OS ?
3.After cold backup how he came to know that one datafile is corrupted ?
4.When and how datafile became corrupted ?
5.How he taken cold backup ? Was db running fine just before shut immediate for cold backing ?
6.What he has done so far to restore the cold backup ?
7.What error he is getting right now ?
Here problem is corrupted datafile. So, first let come problem clear from OP, ask all missing question in one go, and then start helping is the right way... (my personal opinion, may be wrong!).

How to Create new database from cold backup files.

Dear Experts,
I have an oracle 10g databae on windows 2003 server.
The database is in Archive log mode and backup strategy is Taking cold backup ever night.
Backup steps:
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location.
Startup.
I have taken a backup at Tuesdaay 1AM and I have archive logs also.
On Wednesday, I want to Create a new database on another server with the available cold backup files and archive logs. I want to recover the database upto 4PM Wednesday. How can I do this.
I am not using control file auto backup or control file backup to trace.
Please help me how can I do this. I am new to oracle database Administration.
--Thanks

The steps :
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location -- you mean the alternate location for the new databaseare correct (except that I would say "alternate location for the new database").
If you do not have controlfile backups, you cannot either OPEN the database or RECOVER the database until and unless you CREATE the Controlfiles. You have to generate a CREATE CONTROLFILE script using a BACKUP CONTROLFILE TO TRACE from the Production serer and create the controlfile on the new server.
BEFORE the Startup, I would use
RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;The "using backup controlfile" tells Oracle to continue attempting Recovery -- ie doing a RollForward -- till the last archivelog made available to it.
For the Recover command, you then keep applying the ArchiveLogs from the Tuesday 1am ColdBackup upto Wednesday 4pm.
Once you have applied the last ArchiveLog, you do an
ALTER DATABASE OPEN RESETLOGS;Here are my notes of doing a RollForward "Recovery" from a Cold Backup :
http://hemantoracledba.blogspot.com/2007/05/rollforward-from-cold-backup.html
If you are attempting all these steps on a different server from your current Production database, you should be safe.
Once you OPEN the database, you can use CREATE CONTROLFILE or the NID utility to rename the database.
If you are attempting to create the new database on the same server there are many other precautions you have to take and unless you have experience with cloning databases, I would advice you against doing so (only the RMAN DUPLICATE DATABASE command has a safer method of cloning a database).

Upgrade 10.2 to 11.2 manualy using cold backup copy on new server.

Hi,
I am going to manually upgrade my databases to 11.2 from 10.2. I will use cold backup of 10.2 and copy in to the new server Red Hat Linux 5.
I got a Note (742108.1) done for upto 10.2.0.5 and it tells to set
orapwd file=$oracle_HOME/dbs/orapw<SID>
But my upgrade path is 10.2 to 11.2 and i would like to verify whether i need to do the same before startup in upgrade mode?? Nothing mention regarding this in Upgrade Guideline. Just telling only to copy password file to $oracle_HOME/dbs/
if so how i set it ? i mean in $ prompt or SQL Prompt?

I have 10 databases in one server and 2 seperate servers. I will do 3 changes mainly 32 bit to 64 bit, Suse Linux 9 to red Hat Linux 5 and 10.2.0.4 to 11.2.0.1
So best path to do all at once is cold backup and i verified it from oracle Support as well. because 32 bit o 64 bit conversion will automatically happend when upgrade.
My databses are nearly 300GB each and not much big . use for datawarehouse.

How to Recover database from old backup and full archive log file

Hi Oracle expert!
I met problem when restore my oracle database.
In my case:
- My database version: 10.2.0.2
- I have a database full backup (01-Nov)
- I have all Archived log file from (01-Nov -> 05-Nov)
- My database drop in 05-Nov with disk error (no datafile, no redo..).
- I have no any RMAN backup from (01-Nov -> 05-Nov)
How can i restore my database to 05-Nov?
Thanks

Hi Chinar.
When i used RMAN flow as your step, but i met the problem!
- After recover database i select sequence#, applied from v$archived_log;
--> it apply newest archived log that i had.
- but when I select Data from table created between 01-Nov to 05-Nov, it not found!
Not the same way the step:
SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL?
It apply newest the same archived log i had table created between 01-Nov to 05-Nov.
How can i do with RMAN to recover my table?That is not possible,if your all available archive logs applied using rman or through sqlplus(recover database using backup controlfile until cancel) and one of these logs contain your table then there are not any problems.So there are not any difference between recovery using rman and user managed(using sqlplus),but there main matter is applying all archive logs.So first check through rman list copy of archivelog all or list backup of archivelog all and identify there in rman repository is any information or not about these logs.

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.

Using Cold Backup for a 42GB database

I plan to have a Cold backup for a 42GB db (v 8.1.6). Since it's size is quite large, i am not sure how to back it up quicker.
I did a trial copy for a 3GB file, it took almost 9 hours to finish.
Please help!!!
Thanks a lot :)
Tracey

I did a trial copy for a 3GB file, it took almost 9 hours to finish.Wouaw, what is your network ?
You can copy the files in local, restart db, and move files on an other drive trough network, like this, the service is not down for a long time.

Create a standby controlfile using cold backup

Hi All,
We have to setup a DR for a production database.
Here we have the coldbackup which backups all the datafiles and the control file from the production database.
For cloining we generally copy them to another instance and then create controlfile manually. But for setting up as a DR , we would be creating it for standby controlfile.
I tried to google but I am not able to find a way to create a standby controlfile from the existing controlfile cold backup.
OS version solaris 10 , database version 11.2.0.1

Here we have the coldbackup which backups all the datafiles and the control file from the production database.
For cloining we generally copy them to another instance and then create controlfile manually. But for setting up as a DR , we would be creating it for standby controlfile.
I tried to google but I am not able to find a way to create a standby controlfile from the existing controlfile cold backup.
OS version solaris 10 , database version 11.2.0.1
Regards
KK

SQL>1) Taken backup of current controlfile
2) Deleted Current controlfiles
3) Restored using standby clause from current controlfile
4) Mounted & now controlfile type is Standby
Try in this way when you have cold backup. :)

Some More information:-
Even if your database backup is old, still you can create a new standby controlfile and restore new controlfile and restore database. Later after starting MRP all will be synchronized. No issues
