Oracle Restore from Online backup without any archive logs

Hi,
May be a dumb question. If I have a good online backup (say it took 2 hours to do that. And there is database activity while backup is going on), and lost all the archive logs happened after the online backup, is it possible at all to do the restore using that backup? complete or incomplete? and bring back the database to normal operation mode? Some details on this.
Thanks.

Let us see the reasoning behind this.
Database:WORLDDB
WORLDDB configuration:-
TBSP_WDB
->TBSP_WDB_01.dbf
->TBSP_WDB_02.dbf
SYSTEM
->SYSTEM.dbf
USERS
and so on for the tablespaces.
CASE 1:-
User managed backup.
You issue
ALTER TABLESPACE TBSP_WDB BEGIN BACKUP;
DB keeps working all transactions are recorded in the redo stream, the scn information is not updated in the file header.
Also note that the other tablespaces were been continuously worked on hence their scn numbers are a moving target.
http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96572/osbackups.htm#10012
So if you begin tablespace TBSP_WDB backup at time t1 and by the time you are done with your backups you are at time t2, you will need all of the archive log's between time t1 and t2.
CASE 2:-
If we do with rman, rman takes care of the file header update information and goes on its merry way, those details are hidden from the end user. If one of the tablespace is fractured, updated while backups are going on , rman knows about it and will re-read the affected blocks in question.
My thinking would be that you might need archive logs, unless it is a cold backup, with switch logfiles in between.
If you do hot backups you need archivelogs is my thought. The number of archivelogs required will be decreased considerably through rman.
http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmconc1.htm#458821
Summary:-
Either way archivelogs are needed.

New phone restored from wrong backup. Any suggestions?

I just bought a new Iphone. I was trying to set it up from my computer. It was restored from a back up that has an old Appe ID. I don't know the password for it, so I can't erase the phone myself and use the new backup. Any help on what to do?

if the iPhone goes through the cycle again every time it is re-connected to your Mac, there is a problem with the old backup or with the new iPhone.
Try restoring the new iPhone with iTunes as a new iPhone or not from the backup. If no problem after this, bingo.

I was just wondering if there was a way for me to restore from iCloud backup without restoring the device itself again.

I had restored my iPod touch 4th generation this morning and accidently hit set up as new device. Is there a way where I can take everything from iCloud and put it back on my device without restoring again? Thanks.

Welcome to the Apple community.
Back ups can only be used to restore the phone as a whole, you cannot selectively restore from a back up.

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.

I just updated my iphone to ios7 and I keep getting stuck at the 'Set up your iPhone' screen. I click 'Restore from Itunes Backup', but it only ends up restarting after restoring and fails to get past the 'Set up your iPhone' screen. Any ideas?

Normally, I would suggest restoring the iPad and uninstall and reinstall iTunes but you have done both of those things - more times than you ever imagined!
Have you thought about turning auto syncing off?
Without connecting your iPad to your laptop, start iTunes. Click on Edit. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
If you do this you can backup the iPad right away before it syncs. You may want to go into all of the iTunes tabs and just make sure that all of the current content on the iPad is selected to sync before you actually do sync.
This doesn't solve the problem, but it would prevent the automatic sync and erasing content. Hopefully, in the next few days- when iOS 5 is released - you will also be relieved of this weird iPad behavior - since the iOS devices are supposed to become PC free.
BTW - and this is no excuse for what you are experiencing, but I have found that some of the game apps that I had on my iPad turned out to be quite troublesome and after I removed them, my problems went away. I know that is almost sacrilege with regard to the Angry Birds addiction .... But I'm just saying ...

Restore controlfile from tape backup without autobackup setting on

I am testing a scenraio of restoring control file if we loose all control files.
My RMAN settings for CONTROLFILE AUTOBACKUP is OFF. But, I have taken a backup of controlfile using 'BACKUP CURRENT CONTROL FILE' .
When I tried to restore control file. I am receiving following error:

My question is, How can I restore control file from tape backup without CONTROLFILE AUTOBACKUP setting ON.
It sounds like, There is no way we can restore control file from tape backup if you've not set the CONTROLFILE AUTOBACKUP is ON.
Please advice

When all controlfiles are lost and a recovery catalog is NOT used, RMAN has no information , where to find the controlfile backup. It's not enough to specify the channel, such a channel could hold many different backups from many different databases. You have tell , which database and which backupset. Modify your run block:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';

Someone tell me how I can sync my music to my iPhone without it saying on itunes "set up as a new iPhone" or "restore from the backup of: iPod"

someone tell me how I can sync my music to my iPhone without it saying on itunes "set up as a new iPhone" or "restore from the backup of: iPod"

You must be trying to sync it with a different computer than the one it used last. No, there is no other way to do this.
The iPhone may be synced to one and only one computer at any given time. If you choose to sync it to another, you can do that as often as you wish, but its content is erased first.

Since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists

since you can no longer backup to disk, how to restore from external drive without losing all ratings and playlists?

My own opinion is that you should install the later appropriate version of Silverkeeper. That said, I would in fact recommend if you can wait a few days for an answer, that you email the La Cie Silverkeeper backup team via the email link on the site at http://www.lacie.com/silverkeeper/
They are careful to say they are not officially providing a backup service, but when I emailed them with a query regarding usage about a year ago after downloading Silverkeeper for myself, I got a reply within a couple of days that cleared up my question.

Time Machine will not let me restore from recent backups. I can see them on the external drive but will not restore sooner that June of 2013! Any suggestions?

All I can suggest is that you open that file on the MBA and save it as a new file, then see if you can open the new one on the iMac.

How to restore from Time Machine WITHOUT install discs using a second Mac

It's a question that is asked repeatedly all over the web by Mac users like me that bought in to Time Machine (TM) on the assumption that if their computer died one day it would be a piece of cake to restore from it, only for that day to come and then to be told "ahh, okay the first thing is to get your computers install discs..." (loud crashing sound of world falling around ears).
I've never been able to afford a new Mac and both of my machines were bought second-hand. Neither came with Leopard (both have Tiger and have been upgraded to Leopard via the net). This was never supposed to be a problem as I've been backing up with TM. However it appears that Tiger discs are as much use as an inflatable dart board when it comes to using TM. So I've been faced with the possibility of having to spend £130 (about two hundred Pres Sheets, Yankees) on the Leopard install discs just so that I can have the option of restoring from TM. Bonkers.
However after much nashing of teeth, a very long weekend learning all sorts of things about 'Target Mode', 'Single User Mode', 'Verbose Mode', 'Open Source 9' etc the following solution has worked without the need to go out and buy those over-priced discs...
What you will need:
1 broken Mac requiring restoration
1 second donor Mac running Leopard (or Snow Leopard so long as the broken Mac can run it)
1 firewire cable with the correct fitting at either end to attach both Macs together
1 Time Machine backup
Note: The following is for when you have given up trying to boot from your hard drive. In my case I couldn't boot in to Safe Mode etc. so was forced to format my drive and re-import everything. If you've read this far I'm assuming your at the same point as well and have tried everything else that's out there first.
Also - both my Macs are Power PC's so can't run Snow Leopard, so I can't say 100% this will work with SL (Intel) machines. From what I've read Snow Leopard will work with this procedure too, but if you've found differently please feel free to add your experiences below...
STEP ONE: Format the corrupt Hard Drive or replace with a fresh HDD
*Link the two computers with a firewire.
*If you're replacing your HDD, remove your corrupted hard drive from the 'broken' machine and insert a new one.
*Power up the broken Mac whilst holding down the 'T' key. This will start it up in Target Mode and you'll get a nice firewire symbol floating around that machine's screen.
*Power up the second 'healthy' Mac. This will be our 'donor' machine. When it starts up after a few seconds you will see the hard drive of the broken Mac appear on the donor Mac's desktop.
*Using your donor Mac's 'Disc Utility', format the broken Mac's hard drive (now's the time to partition it etc. if you want to).
STEP TWO: Clone your donor Mac
Your broken Mac is no longer broken and now needs a new OS. But you don't have the discs, right? Well get this... you can clone your donor mac on to your machine, even if they are totally different i.e. a laptop on to a tower.
*Again using Disc Utility, click on your donor Mac's hard drive. The restore tab appears as an option.
*Click on restore and drag the donor Mac's hard drive that contains the operating system in to the Source box.
*Drag the newly formatted hard drive on the broken Mac in to the Destination box.
*Click restore. Your donor Mac's hard drive will now be 'cloned' on to your no-longer-broken Mac. Once this is done, eject the first Mac's hard drive from your donor Mac's desktop. You no longer need the donor Mac.
Ta daa! Your machine now starts up happy and smily again. Time to restore all that stuff that's been sat on your Time Machine drive...
STEP 3: Restore from Time Machine using Migration Assistant
This is the really clever part that prompted me to write this piece in the first place. Time Machine IS accessible without those Leopard install discs you don't have. You need to use something called 'Migration Assistant'.
*Start up your machine as normal and you'll see it is an exact clone of the donor machine. Weird huh?
*Attach your Time Machine hard drive. It will show up as an icon on the desktop and because of it's size, you'll be asked if you want to use it as a Time Machine backup. Err, NO YOU DON'T! Click 'cancel'.
*Open Migration Assistant (if you can't find it just type it in to Finder and click). There are three options, the middle one being to restore from TM or another disc. Yup, you want that one.
*Migration Assistant will now ask you what you want to restore in stages, firstly User Accounts, then folders, Apps etc. It will even import internet settings
And that's you done. Let Migration Assistant do it's thang... altogether I had about 140gb to restore, so it wasn't exactly speedy. This wasn't helped by the fact that my TM hard drive is connected via USB (yes, I know). Just leave it alone and it'll whirr happily away...
Before I go - you don't have an option of when to restore from, and will restore from the last Time Machine save. At least then you should be able to access TM and go 'backwards' if you need to.
Also - for a Mac expert, the above will be up there with 'Spot Goes To The Farm' in terms of complexity. However, for the rest of us the above is only available in fragments all over the net. By far the most common response to 'how do I restore from Time Machine without install discs' is 'you can't'. If I'd found the above information in one place I could have saved a lot of hair pulling and swearing over the last couple of days, so forgive me for sharing this workaround with the rest of the world. Meanwhile your expertise will come in very handy for the inevitable questions that will get posted below, so please feel free to help those people that won't be sure if this solution is the right one for them. I'm no expert, I just want to help people that were stuck in the same situation (and looking at the web, there's a LOT of them).
Hope this is of use to someone, thanks and *good luck*!

Most maintenance and repair, restore and install procedures require the use
of the correct OS X install DVD; be it an original machine-specific restore/install
disc set or a later retail non-specific general install disc set.
By having an unsupported system, perhaps installed via an illegal download or
other file-sharing scheme, where no retail official discs are involved and the
initial upgrade was done by other means outside of the License Agreements,
you are asking us to discuss a matter of illegal installation and use of a product.
There are no legal complete OS X system download upgrades online; only bits
that are update segments to a retail or as-shipped machine's original OS X install.
+{Or an installation where a previous owner had correct retail upgrade discs, &+
+chose to not include them with the re-sale of the computer it was installed in.}+
However, to answer the initial question. To get and use an externally enclosed
hard drive in suitable boot-capable housing, and get a free-running Clone
Utility (download online; often a donation-ware product, runs free) you can
make a bootable backup of everything in your computer to an external HDD.
This is the way to make a complete backup to restore all functions to the computer.
The Time Machine has some limits, in that it can restore only that which it saves.
It does not make a bootable clone of your entire computer system with apps and
your files, to an external drive device. A clone can. And some of the clone utility's
settings can also backup changes to an external drive's system; if that other drive
is attached to the computer correctly.
Carbon Copy Cloner, from Bombich Software; and also SuperDuper, another of
the most known software names you can download and use to clone boot-capable
system backups of your computer's hard disk drive contents, are often cited.
However you resolve the matter of the running OS X system in your computer,
derived from what appears to be questionable means, is part of the initial issue.
Since you do need to be able to fix an existing installation by unmounting the
computer's hard disk drive and run the computer from the other (install disc or
system clone) while it is Unmounted; and use the correct Disk Utility version to
help diagnose and perhaps be able to fix it. You can't use a Tiger version Disk
Utility to fix a Leopard installation, and so on.
So, the situation and replies as far as they can go (since the matter does
constitute an illegal system, if it was arrived at without correct discs) is a
limited one. And file sharing of copied Mac OS X (and other) software is
also considered illegal.
And, one way to get odd malware and unusual stuff, is to get an unauthorized
system upgrade from an illegal source online. You never know what's inside it.
The other reply was not a personal attack; the matter is of legal status and as
you have a product with a questionable system, the answer is to correct it.
And if you want to save everything in your computer, make a clone to a suitable
externally enclosed self-powered boot capable hard disk drive. With older PPC
Macs, that would best be to one with FireWire and the Oxford-type control chips.
However that works out...
Good luck & happy computing!
