Test Restore Database Instance from Cold backup

Hi - I have a customer who is using an Oracle database instance not in archivelog mode
currently, I have managed to persuade them to backup at least weekly using an RMAN cold backup.
Prior to my being allowed to do anything else they want to perform a test restore from the cold backup
I want to find a simple procedure to do this which will enable me to tick the box then hopefully I may be able to persuade them that Hot Backups are the way to go.
Has anyone got any good suggestions for this please?

Ah if only things were quite so simple - my hands are tied somewhat there isn't a second machine available at the moment so I was hoping to be able to run a test restore to the same machine !
No they do not worry about data in this situation - Oracle is used almost as a query engine maybe a very odd solution as the actual data is not really held within this oracle database but the resultant queries are!
Anyway I think I will just do a virtual restore using the restore database validate command then armtwist a couple of managers!
One of the areas they had difficulty with is that apparently they had archivelogging on but the rate of writing archivelogs was huge and it was affecting performance. I am not knowledgeable enough to know how to tune that problem!!

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;

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.

Restoring tigger from cold backup.

Hi
I have one problem..... recently i have drooped 1 trigger by mistake of one of my user in database. Now the problem is... we never take the logical backup of that DB.
Backup mechanism of the database is Cold Backup and size is *2TB*.
Now i have to restore that trigger from the cold backup with minimum effort , do i have to create the Clone database with the Cold backup using all the datafiles ...? or System tablespace ( or datafile) and default Schema tablespace(Schema which holds the trigger and its tables) in enough for restoring the trigger ?
I hope i am clear with my question. please let me know if you need more details.
Please suggest some best and fast way to solve this problem.
Thanks,

You need to restore enough to OPEN the DB can you please elaborate this clearly....
The version is :
Oracle Database 11g Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 ; Production

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).

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 do media recovery from cold backup?????????/

Hi
i take cold backup of my 9i database ....
in case my database is up .....
how will i recover my database if i lose a single database file and i want to recover it from cold backup......
Thanks in advance
Gagan

Here you go
These are the steps:
1. Restore the lost file from a backup.
2. If the database is down, mount it.
SVRMGR> STARTUP MOUNT PFILE=<location_of_pfile>;
3. Issue the following query:
SVRMGR> SELECT V1.GROUP#, MEMBER, SEQUENCE#,
FIRST_CHANGE#
FROM V$LOG V1, V$LOGFILE V2
WHERE V1.GROUP# = V2.GROUP# ;
This will list all your online redolog files and their respective
sequence and first change numbers.
4. If the database is in NOARCHIVELOG mode, issue the query:
SVRMGR> SELECT FILE#, CHANGE# FROM V$RECOVER_FILE;
If the CHANGE# is GREATER than the minimum FIRST_CHANGE# of your logs,
the datafile can be recovered. Just keep in mind that all the logs to
applied will be online logs, and move on to step 5.
If the CHANGE# is LESS than the minimum FIRST_CHANGE# of your logs, the
file cannot be recovered. Your options at this point would be to restore
the most recent full backup (and thus lose all changes to the database
since) or recreate the tablespace as explained in scenario a.
5. Recover the datafile:
SVRMGR> RECOVER DATAFILE '<full_path_file_name>'
6. Confirm each of the logs that you are prompted for until you receive the
message "Media recovery complete". If you are prompted for a non-existing
archived log, Oracle probably needs one or more of the online logs to
proceed with the recovery. Compare the sequence number referenced in the
ORA-280 message with the sequence numbers of your online logs. Then enter
the full path name of one of the members of the redo group whose sequence
number matches the one you are being asked for. Keep entering online logs
as requested until you receive the message "Media recovery complete"
7. If the database is at mount point, open it.

Rebuild from cold backup on windows

Greetings,
Our Db was destroyed. We have a new machine now, and I have loaded the OS ( windows NT ), and the Db software ( Oracle 9i ). I have a cold backup of the old database that I would like to use to get the old system back. Where can I find documentation explaing the required steps to getting the Database back on line ( on Windows as a service )using a cold backup?
Any help or advice are greatly appreciated.
Thank You.

Hello,
If the location of the files didn't change reconstructing the database instance from coldbackup takes just few steps
1.) Create an instance
Oradim ânew âsid testdb -mode a
2.) Connect to the instance
Sqlplus /nolog
Connect / as sysdba Ã
3.) Start the database
Startup pfile=localtion to inti.ora
Let us know your case details and I would perhaps be able to help. I experienced the same problem and successfully rebuilt the database

I need to know how to restore a file from sessionstore-backups?

I had 48 tabs open in the last session before i did this and cant seem to get them back. How do I restore a file from sessionstore-backups? The latest upgrade file based on the date probably has all of the tabs I need.

Updated iPad 1 to IOS 5. When trying to restore my iPad from my backup it gets half way through and the iPad reboots and iTunes says "An error occurred while restoring this iPad (-1)"

Updated iPad 1 to IOS 5. When trying to restore my iPad from my backup it gets half way through and the iPad reboots and iTunes says "An error occurred while restoring this iPad (-1)"
I have tried to restore my contacts and company data at least 20 times and every time half way through THE iPAD REBOOTS! When it boots back up it is at the brand new iPad screen.
This makes me angry as I do not use the iPad for fun and games. I use it for business. My company data and records for the last year are gone. ALL of my out standing customer invoices are gone. ALL payments received are gone! ALL Business contacts and emails ARE GONE! All my company, personal email accounts and settings ARE GONE!
What am I supposed to do now? In 6 hours I have to get on the road and conduct business with a empty blank factory out of the box iPad. How am I supposed to know who owes me money or who has paid their bills Apple? All of my meetings and calendar dates are GONE!
Everything was supposed to be backed up and restored after the update!
Question???WHY DID YOU MAKE THIS UPDATE WIPE OUT ALL SETTINGS AND APPS ON THE iPAD??? All the other updates left everything on the iPad intact and ONLY upgraded the IOS,and when it was done everything was still there.
Yes! I have done everything. Rebooted computer, checked for updates, Hard booted iPad, Factory restored iPad to ios 5 twice, tried every usb port I have, unplugged all other usb components.
Everytime half way through "Restoring iPad from backup..." The iPad turns off shows a spinning circle then shows the Apple logo and takes me to the brand new iPad setup screen.
Apple, you have no idea the level of stress you have created today.....

Check the console app to see if there are any error messages. I had one app showing an issue (Pet Hotel) the error was (truncated):

I manually snyc'ed that particular app and then re-ran the restore and am now the proud owner of a working iphone. Not sure it is the same problem or app but looking in the console was the key!

Because it says it's incompatible when it can't be, I got hope. I get error messages all the time with my iPod and iPhone that it cannot sync and that 'this device is not capapble of connecting to iTunes' stuff. I literally forget that happened, plug it in again and it works, I later realize that iTunes made a mistake, they do that.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
