RegardsIf your OS is windows then you have to create OracleService using oradim utility,then create need directory for data/control/log files and according background/diag/trace also parameter file.
After creating these directories startup mount database using STARTUP MOUNT PFILE='PFILELOCATION' then issue command RECOVER DATABASE USING BACKUP CONTROLFILE in this case oracle will read default location of archive logs and will apply,if this directory is different then main server then execute RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL and apply archive logs manually and open database with ALTER DATABASE OPEN RESETLOGS.

Restore from cold backup (rac server)

Hi All,
Oracle version : 10g
OS : SunOS dixie1 5.10 Generic_118855-36 i86pc i386 i86pc
I am having cold backup of RAC server (2 nodes), I want to restore from cold backup.
The problem is that : when i performed the cold backup using rman at that time Oracle was having 3 ASM diskgroups.But unforunately that disk is no more in use due to some fault.
Now my question is how can i restore from the cold backup as when i'll restore from the cold backup this will ask for the same ASM diskgroups.Even more if i creates the same diskgroup with the same name and same configuration then my doubt is that rman will allow me to restore the same from the cold backup as ASM disk header changed now ?
Thanks,
Vipin

Yes.You can do these and restore/recover your database.First you need startup your ASM instance then create your ASM disk groups and do following:
1.Edit pfile and change controlfile location to diskgroup(Consder that +dgr1)
2.Restore controlfile to this disk group using backup of controlfiles(you say that is cold backup)
rman target /
/*Instance need starting up from pfile*/
startup nomount ;
/*then restore controlfile,give full path of controlfile from coldbackup*/
restore controlfile from 'coldbackup_location\coltrolfile';
alter database mount;
catalog start with 'coldbackup_location';
backup as copy database format '+dgr1';
switch database to copy;
alter database open;

A question about restoring from cold backup(control file backup not clear)

Hi,
I had another question about restoring the cold backup. My database is in noarchivelog mode and after taking a consistent cold backup, all I need to do is to restore the backup right? -Why I got this question is because: when I backup my control file to trace, I see statements like this:-----
-- Commands to re-create incarnation table
-- Below log names MUST be changed to existing filenames on
-- disk. Any one log file from each branch can be used to
-- re-create incarnation records.
-- ALTER DATABASE REGISTER LOGFILE '/uo1/app1/arch1_1_647102958.dbf';
-- Recovery is required if any of the datafiles are restored backups,
-- or if the last shutdown was not normal or immediate.
RECOVER DATABASE
-- Database can now be opened normally.
ALTER DATABASE OPEN;
My database is in noarchivelog mode now so don't know why these statements (of register the logfile) is there in the backup of control file? so when I restore the cold backup of this database, it will still work correct? (there is no logfile I have only CRD files in cold backup -no archive log files.)
thanks

How to restore cold backups on other server

Hi all
On Oracle9i production server, we have windows scheduled job to take the cold backups every day night. The size of the database is 2GB.
Now, the cold backup consists of
- Database files & Log files
- Parameter file
- Control file.
I am required to check the validity of the cold backup we have. So, I need to restore the database in another server.
So, please provide me the steps I need to do to restore the database.
Thanks.

Please do not confuse between the backup copies you have. Ensure that you have the latest copy whether cold or hot. If you have COLD copy then simply replace all the data files, redo log files, and the control files and start the database it should start. I do not understand your back up strategy because if you have a Hot backup then why do you need a cold backup. Please let me know in what mode your database is running?

Partial restore from Cold backup

Hi,
I want to create a copy of our dev database to another server.
We have Oracle 10.2.0.4 server running on Solaris 10 OS.
This database is @ 120GB in size and has got lots of application data.
Now I want to create a copy of this DB without having the application data.
Can I do the following?
1. Take cold backup of this database.
2. copy the oracle binaries, controlfile, logfile to target server.
3. copy the datafiles only for SYSTEM, UNDO, TEMP and SYSAUX tablespace to target.
4. restore / create the new database? - will you pls provide me the steps for this?
Thanks,
DR

Hi,
In order to create a clone of your dev database trough the copy procedure you have to follow these steps:
1. Take a cold backup of your database files (and i mean ALL the files: controlfile, data files, etc)
2. Take a "cold" backup of oracle binaries (with your instance down, copy $ORACLE_HOME dir)
3 You have to ensure you have the directory structure in the new server.
4. The new server must accomplish with all the libraries requiered for clean installation (that's because you have to relink oracle binaries)
5. Once the oracle binaries are in $ORACLE_HOME, run "relink all". If everything is fine, you don't have to see any errors; if not, check the log.
6. After a succesful relink, you have to copy the database files on their corresponding directories.
7. Start the instance.
I know, it's not a friendly process, but it works.
I offer you another way.
1. Install another engine (same as your dev server).
2. Clone your dev database with one of the following procedures:
2.a. RMAN Clone
2.b. Directly import with oracle data pump.

ORA-00313: open failed for members during restore from COLD backup

Hi all,
I took a cold backup of an 11.1 database using RMAN (database in mount state).
I used the following command to restore it:
restored the controlfile and then
RESTORE DATABASE FROM TAG 'TAGxxxxxxxxxx';
Now I'm restoring it and it's taking too much time. When checking alert log it says:
ORA-51106: check failed to complete due to an error. See error below

RMAN is still in progress, why does it complain about redo?
I'm not doing recovery since it was a cold backup.

Cold Backup on windows Server

Hi All;
OS: Windows
DB: 10.2.0.3
I am trying to schedule a cold backup, I was wondering if I can just down the oracle database service and then directly copy the files using copy command and post the completion of copy of the files I will up the oracle services.
Will this method work I cannot test the same as I do not have access to the server right now.
Regards,
Sphinx

Yes you can, by default stopping the service will execute a SHUTDOWN IMMEDIATE. To check this, look at the registry keys named something like
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\KEY_OraDb12c_home1\ORA_ORCL_SHUTDOWN
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\KEY_OraDb12c_home1\ORA_ORCL_SHUTDOWNTYPE
and you'll see the settings.

ORA-00314 - Restoring from Cold Backup. ( Redologs on Raw Disk startup)

Greetings,
We're running Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production ( Solaris Sparc )
we've recently switched to redologs on raw disks to improve DB write performance. Have taken a cold backup of db , But db denies to open normally after restoration.
Any ideas what could be wrong? and how to fix this?

Restoring inconsistent cold backup

Hello all.
Here's the scenario: I have a 9.2.0.1 database, in noarchivelog mode, running on Windoze XP. While the database is running, I took a backup of all the datafiles, control files and online logs using copy and paste on windoze. After the copy was done, I have shut down the database. I copied back into the original location the backup of the datafiles I made earlier.
My question is: How I go about to restore this database ? I dont care wether it is consistent or not, I just want to open it to make an export out of it
Things I have tried so far unsuccessfully:
allowresetlogs_corruption
allowreadonly_corruption
If you could shed some light on it on the steps I would need to make, that would be appreciated.
Thanks

What have you tried to far (specifics please, not general statements)?
I have done something close to what you want do a couple of years ago for an Oracle 9.2.0.4 DB on Linux and am looking for my notes. One key thing I found was to not try to change anything but just get a DB up and running that would let me get the data out. That means don't try to use different file paths or anything other changes.
It involved creating a new minimal database from scratch by hand that has the same name, paths, block size as the old one. In my case this minimal DB only had the system_01.dbf, undotbs_01.dbf and users_01.dbf data files even though I ultimately needed access to about 40 others.
The idea is to get a template DB in place that refers to the same paths, then shut it down and replace the minimal system_01.dbf file with the one from your backup. It turned out for me that Oracle could open, load and use my old system tablespace even though it referred to tablespaces that didn't exist yet in the new minimal system; obviously I couldn't use them yet but they didn't cause Oracle to fail to start.
1. You can toss the redo logs since there is nothing in them you need or can use and you will never be able to read them anyway.
2. You will need to create the instance and DB using the same version of Oracle that you had. There were key differences between the early Oracle 9 versions and I wasn't able to get around them.
3. Create an instance for the correct DB version if you don't have one. The easiest way to create a new one is to do a default installation from the original set up files but DO NOT create a database. When given choices use the same values (character set, paths, etc) as your old DB.
4. You will need a text version of the init.ora file in the same location (name and path) where it was before - the character set and block size have to match what you had before. If you have a copy of this file you can try it first. If you don't then create a minimal file; that is, no entries that are not necessary. Oracle comes with a sample with a lot entries commented out.
    a. use the same db_name= parameter in the init.ora file
    b. use a db_files= parameter that is large enough for all of the data files that you will later need access to
    c. use a compatible- parameter that is 9.2.0 and no later
5. You won't be able to use your old, copied, control files since they are binary files and the content won't match the new database; trying to use them will not get you anywhere.
6. Once you can bring up this new DB the first thing you should do is shut it down and take a cold backup.
7. Replace the new system_01.dbf and users_01_dbf files with the ones you copied from the old DB. The new control file can mount and open the old tablespace file and users file since the control file (old Oracle systems only, mind you) have NAME and PATH information but do not care about actual content (how many users, etc).
8. Make sure you can now open and access the DB with your swapped system and user tablespaces. You won't be able to access objects from the system tables that refer to data files that aren't known to the control file so don't even try to yet.
9. You can add your other data files to the DB by doing a CREATE CONTROLFILE command, when unmounted, that adds the other data files that you will want access to. Obviously don't add them all at once; add one and then test to make sure that things are ok. You won't be
It turns out that the control file has the list of datafiles including their names and paths but does not have the sizes; the system tables have the size info and physical info. So you can add a datafile to the control file by path and name without needing to know how big it was supposed to be; that size info will still be in your old system tablespace.I may have missed something and if I fiind my notes will repost with anything else I think of.

RMAN Restore from cold backup ?

Hi ,
I am trying to restore the database from production db using the RMAN cold Backup. Both the prod and test(Restore database) are on the same machine. And also I wanted to have the restore db name should be different.
And the restore db name should be different. What are the options I have ?

Recovery of Database -- Restore from Cold Backup

Hi All
I was trying to understand the possible failures so as to enhance my recovery capabilities of Oracle database 10.2.0.4.
We take weekly hot back up of the database on every sunday including archive logs. Archive logs are also backed up when the log_archive_dest_1 disk space utilization grows beyond 80%. All the backup goes into an alterate disk made available on the host. The archive back up is triggered mostly twice a week, on one of the thursday/friday/Saturday depending on the redo generation in that week.
Imagine we have a failure on thursday leading me to restore the complete database from backup taken on the earlier sunday. I also realise there is 1 archive log from tuesday missing and its not backed up for sure. I restore from backup and try to recover. As all the archive logs are available since Sunday till the point of failure except for that one missing file from Tuesday, I want to recover the database until the point of failure although there is one log sequence missing in archive destination. how can I do that? Is it possible? Please advice.
I remember reading on net that recover database command can be hinted by an init parameter so as it does not check for sequece numbers and continue to apply archives (does not check sequence numbers) as they are available. But I am not able to recollect it exactly. while I was searching on net, I came to this forum hoping if some one knew it.
Let me know if you know how to go about this. Thanks in advance.

You cannot skip an archivelog (there is no init parameter to do so).
Think about this :
Imagine that there is one very long transaction. A transaction that deletes or updates 1 million records. With the redo logs being, say, 100MB each, the transaction spans multiple redo logs.
These redo logs are archived as, say, sequence #121 to 128.
Supposing that sequnece #123 is deleted by mistake.
Can you recover the database with sequence# 121, 122, 124-128 ? Can that transaction be consistent ?
OR think about this :
A redo log file is 99% full. A transaction for 1000 rows begins. All the redo entries for that transaction do not fit into that last 1%. The transaction spans into the next redo log file.
Can recovery be done with either of these missing ?
If you think through these scenarios, you will see that there will almost always be transactions spanning redo logs. That means, that you cannot skip redo logs during recovery.
