Restoring 20/25 % from the RMAN Backup
Hello Guys,
I have a production environment with size of TBytes, and I would like to create a new test environment but with a smaller amount of data, so i need to take a hot full backup from the database then restore only 20% to 25% from the original data to a new fresh database.
The question, is this scenario Doable ?, do we have particular way to do this approach ?
Thanks for your help !

Hello Paul,
You mean that if i have some constraints, it will be difficult to take the backup using the expdp ?, now we are deciding to use the expdp/impdp to take the backup from the production database and restore it in a new fresh database, please consider that we will use the SAMPLE to take around 20% to 25% from the original data.
Do we have have any restrictions for this scenario ?
Thanks for your help.
Mahmoud Darwish.The problem is that the SAMPLE (or nothing else inherent in expdp) is going to know about cross-table relationships. So it samples 20% of your invoice_detail table. What's to tell it which rows from invoice_header are needed to match those specific invoice_detail rows?

I tried to restore my iPad from the cloud backup but the iCloud returned the following message 'no backup available'? This after happened after I created the backup today and the same was confirmed at the Apple Store attendant
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! -
How to restore one table from the previous backup in 9.2.0.8 version.
Hi,
How to restore one table from the previous backup in 9.2.0.8 version.
Thanks
-GangaHi,
What is the table you want to restore?
Using export/import is supported with Oracle Apps database (for full database exp/imp, and certain schemas like custom ones). For the Apps schema, I believe it is not supported due to object dependencies and integrity constraints.

My dad and i,have the same icloud id,when i updated the software (to ios 8.1.3) i have my dad´s photos on my iphone.And want my photos back (i tried by restoring my phone from my last backup)but still have my dad´s photos in my device
And that's exactly the problem, because everyone should have their own account for iCloud. You can share an Apple ID for iTunes & App Store purchases, but you shouldn't do that for iCloud (Mail, Calendar, Contacts etc. ... ...and Photos). The problem of using the same account together could mean that only your dad's photos were stored.

Restoring a photo from the iTunes backup of the iPhone
My son deleted a picture of himself (he's 11) from my iPhone that he didn't want me to have. I wanted to restore it from a backup of the phone that I made last week. How do I do that?
LisaThanks. I'm restoring it now. All of the conditions that you mentioned were true. There were two pics that I took at the Penguins' playoff game last week that wouldn't have been on the backup. I didn't know if those would be wiped out or not so I copied them to my PC first before I started the restore. Other than that (and a ringtone but I can recreate that), everything that you mentioned was true. It's kind of a joke between my son and me -- it's just a stupid pic of him sleeping on the couch (though he claims he wasn't sleeping). He thinks it's over now that he deleted it from the phone. Joke's oh him...
Thanks.

anyone have any revenue to climb it?There is only the processes parameter in PFILE.

Create a database from 8i RMAN backup
Hi,
I am in need to recover some historic data from a historic database's RMAN backup.
The situation is ... I have one old RMAN backup of a 8i database which includes datafiles, archivellog files and control files. Init.ora file is also available.
I have installed the 8i software in a host and created the oracle service through ORADIM and pwd file through ORAPWD utility. Then copied the init.ora file under 'C:\Oracle\ADMIN\ORCL\PFILE' and the RMAN backup files under 'C:\Oracle\Ora81\DATABASE' folder.
Now I can start the instance with the init.ora file but can not mount as control files are not there. when I try to restore the control files through RMAN as...
RMAN> run
2> {
3> restore controlfile;
4> }
RMAN-03022: compiling command: restore
RMAN-03022: compiling command: IRESTORE

RMAN>
Now without the catalog database how can I restore the control files and the database from the RMAN backup?
I think the old RMAN metadata was stored in catalog database.
Any suggestion please?
regardsSorry I wrongly said that I do not have the DBID, I have DBID but I have controlfile backup as RMAN backupset, not in Binary. So even if I set DBID, RMAN asks for the catalog database, which is not available.

Database restore from old rman backup
Hi Friends,
My database version is oracle 10.2.0 O/s : Windows
I have a production database of an outlet. Yesterday night 11pm they have done some wrong transactions and whole stock is showing wrong.
They have taken a export backup at 9.30 pm and latest archives are there.
We have a rman backup on April-30,2008. when I am trying to restore from the old rman backup the controlfile I am unable to do it.
Can any one of you help me out.
thankyou
satyaHi,
I have tried installing in a seperate system and restore the rman backup, as I do not have the controlfile I have taken a standby controlfile and started restoring the rman backup as the old rman backup dbid is different with the current dbid and giving me following error:

How many times can you restore from the same backup?
how many times can you restore from the same backup?
As many times as you want till you delete or modify it.
It's YOUR backup, a copy of all your stuff.
Not some copyrighted, access controlled bunch of bytes representing a picture, a song or a movie, with a bunch of lawyers from the entertainment maff1a hellbent on restricting what you can do with it. -
i have to restore my phone from back up but in order to do it i had to update my software. now that my software is updated there isnt enough room on the phone to back up. is there a way to only restore certain things from the backup like contacts?
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.

I was trying to setup a new ipad. After resetting and erasing the content on the ipad, I would like to restore the ipad from the old backup. Unfortunately the device is not appearing in the list of devices. The sync option under devices is not also active. How else can I restore the ipad?
Sorry, you can't extract those photos from the old device unless you restore the new phone from that backup.
You could of course use a third party software to extract those pics but it will cost you.
If you still have the old phone import those pics to your computer and then sync those photos to your new phone via itunes. -
I restore an old Backup from iTunes to my iPhone 4. The contacts are immediately overwritten by those in iCloud. How do I prevent iCloud contact list over writing the contact list restored from the iTunes Backup?
Yes you can erase the drive and reinstall OS 10.6 from the original disk.
1. Put the disk in and restart the computer while holding the C key down. (The letter C.)
2. When the computer boots you will see the beginning of the OS installation, and have to select a language.
3. On the next screen there is a menu bar. Click Utilities on the menu bar and select Disk Utility.
4. When DU is running, select the hard drive in the left hand column, format should be Mac OS extended journaled, then click Erase.
5. When that task is done, quit DU and proceed with the installation. It will take some time.
6. The computer will restart after the installation is completed and show you an awful noisy welcoming screen.
Then you have to enter information about yourself.
7. Run Software update to get to OS 10.6.8.
Now you can go to the App store and find your previous purchases. You will not have to pay for them again. And you do not have install them one at a time. If for example you want 10.9, and your computer can handle it, go directly to 10.9.1 from 10.6.8. -

How to restore file system of the previous backup from OSB using webtool?
Dear all,
I have some problem regarding to the file system restoration.
For example, I have backed up some files yesterday and today those files have been made change.
So tomorrow I am planning to restore the files from the yesterday backup (the original files before made changes) to other host for testing the data.
Is it possible to do that, since when i restore i can see only the latest ones and search options during restoration are not working well (as date, date range,.....) ?
Your reply to me is very important.
Thanks and regards,
RasmeyThere is no recovery partition on drives which haven't had 10.7 or 10.8 installed. You need to use a Mac OS X install DVD to restore the backup.
