Restore using incremental backup with noarchivelog mode

Hello experts,
We are running SAP on Oracle databse(IN NOARCHIVELOG MODE) for which we are having full offline backup on every sunday and post which incremental backups on rest of the days. We have scenario to do restore db to the state till last friday's incremental backup.
Please let us know the procedure for restoring till that point. If possible using brtools utility(which is SAP specific).
Thank You
Regards,
Venkateshwar

Recovering a NOARCHIVELOG Database with Incremental Backups
Restoring a database running in NOARCHIVELOG mode is similar to restoring a database in ARCHIVELOG mode. The main differences are:
Only consistent backups can be used in restoring a database in NOARCHIVELOG mode.
Media recovery is not possible because no archived redo logs exist.
You can perform limited recovery of changes to a database running in NOARCHIVELOG mode by applying incremental backups. The incremental backups must be consistent, like all backups of a database run in NOARCHIVELOG mode, so you cannot make backups of the database when it is open.
When you are recovering a NOARCHIVELOG database, specify the NOREDO option on the RECOVER command to indicate that RMAN should not attempt to apply archived redo logs. Otherwise, RMAN returns an error.
To recover a NOARCHIVELOG database with incremental backups:
After connecting to the target database and the recovery catalog, place the database in a mounted state:
STARTUP FORCE MOUNT
Restore and recover the database.
For example, you can perform incomplete recovery with the following commands:
RESTORE DATABASE
FROM TAG "consistent_whole_backup";
RECOVER DATABASE NOREDO;
Open the database with the RESETLOGS option.
For example, enter the following command:
ALTER DATABASE OPEN RESETLOGS;

How to restore using increment backup after full backup restore in RMAN?

Hi All,
We have a files of full backup of database after turning on the Archive log.
And after that, daily incremental backup is taken.
Now, i want to restore the the database into a new machine using both files of full and incremental backups. Can anybody give me script for restore of full backup and after that restore of incremental backup?
Thanks,
Praveen.

Praveen,
>>
In my case, i have 2 sets of backups. One is full backup and other is incremental backup. In order to keep the restored database upto date, i need to restore the full backup and then restore incremental backup. Now, i got any idea how to restore using full backup. My doubt is how to update the restored database with incremental backup also?
>>
Restore always looks for level 0 backup, not the incremental backups.
Incremental backups comes in picture during recovery.
During Recovery, Oracle looks for incremental backups, if exists, it will do the recovery with the incremental backups, if no incremental backups available, then, it will look for archived logs.
Therefore, incremental backups never used during restore, they are used only during the recovery.

RMAN backup with NOARCHIVELOG mode

Hi,
Is it possible to EXCULDE TABLESPACE with rman using NOARCHIVELOG database ?
Thanks

Use following persistent setting:
RMAN> CONFIGURE EXCLUDE for tablespace <Tablespace Name>;
N.B. You will not be able to do this for system tablespace.

Restore incremental backup with rman

Dear Friends
can u tell me how to restore an incremental backup with rman? i backup my rman with statement below :
1. backup full database format '/oracle/PRD/sapbackup/%U';
the results was :
-rw-r----- 1 oraprd dba 19006996480 Jun 10 12:08 0ojiit4n_1_1
-rw-r----- 1 oraprd dba 12746752 Jun 10 12:08 0pjiiu6b_1_1
2. after that i do incremental backup :
backup incremental level 1 cumulative database format '/oracle/PRD/sapbackup/%U';
the results was :
-rw-r----- 1 oraprd dba 173400064 Jun 10 13:44 0ujij2k0_1_1
-rw-r----- 1 oraprd dba 12746752 Jun 10 13:44 0vjij3qc_1_1
what statement i need to run for restore the incremental backup?

run{
ALLOCATE CHANNEL c1 DEVICE TYPE DISK;
RESTORE DATABASE;
RECOVER DATABASE;
The above command will restore your database from the last good RMAN backup. Your last backup is incremental level backup as you posted. The above command will fullfill your requirements

Hot backup on NOARCHIVELOG mode?

DB version:10gR2, 11G
Why is it not possible to do a Hot Backup in NOARCHIVELOG mode? What role does archived redo log files have in a Hot backup?

Because it takes more than zero seconds to backup a database.
Say your database consists of 1 single datafile of 10MB. This datafile, at the OS filesystem level, consists of 2,560 blocks of 4KB each.
If you start a backup of the datafile, the OS utility (tar, cp, cpio, whatever command) reads the first 4KB block and copies it out. It then, after a certain time, reads the next block. And so on till it gets to the last block of the file.
However, since the database is "open" transactions may have updated blocks in the datafile.
Therefore, at time t0, block 1 may have been copied out. At time t5, block 128 may have been copied out. At time t32, block 400 may have been copied out. Unfortunately, some user may have updated block 1 at time t3 and block 128 at time t8.
What would happen if these blocks, having been copied out at different times were restored ? They would be inconsistent !!
It is the ArchiveLog mechanism that allows Oracle to know that a datafile was "active" when it was being backed up. Oracle has to "re-play" all changes that occurred on the datafile from the time the datafile backup began (at t0) till it ended (at the 2,560th block).

What files can be excluded from user-managed backup in noarchivelog mode?

what files can be excluded from user-managed backup in noarchivelog mode?
control files,
sqlnet.ora file,
tnsnames.ora,
datafiles associated with read-only tablespaces,
datafiles associated with read/write tablespaces,
of these, what can be excluded and what have to be included?
Thanks.

... and don't forget pfile or spfile... it can help too.

How can i use "icloud backup" with ios 4.2.1?

How can i use "icloud backup" with ios 4.2.1? I tried to update my ihpone 3G wih the newest IOs. Seems not to be possible.

You cannot.
It requires ios 5.
Your iphone can only go to 4.2.1

Had 3G, moved to 3GS. Backed up 3G and restored 3GS from backup with no problem. When I want to add songs, I get itunes message that the new iphone is synced to another computer and now wants to erase everything. How can I add music?

Had 3G, moved to 3GS. Backed up 3G and restored 3GS from backup with no problem on a Dell computer. But now when I want to add songs, I get itunes message of death that the new iphone is synced to another computer and now wants to erase everything. How can I add music without erasing everything on my new iphone?

Yes, I was aware of this but the phrase "Any items imported from audio CDs or acquired from other sources will not copy from your device to the iTunes library." is what worries me. Will this eliminate my Notes, Calendar Events, etc or will it apply mostly just to the music?

Restore DB from backup with move - need to set to single user mode first and then reset to multiuser?

Im going to restore a recent backup from a production server DB to a test server DB and I want to do it through tsql. The DB already exists on the test server, I just want to overwrite it with a fresh copy. There may or may not be some activity
on the test server that is connected to the database, but its not important and can be abandoned/discarded.
This is what Im getting ready to do
First, get an idea of what the file paths are specified in the backup file
RESTORE FILELISTONLY FROM DISK = 'file_back_to_backup here .back .dat etc'
Then, set the DB to singleuser mode, and discard any connections/transactions currently started
ALTER DATABASE MyDBName
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE
Then, do the restore, specifying the paths to the mdf/ldf files that already exist.
RESTORE DATABASE MyDBName
FROM DISK
WITH MOVE 'db logical name' TO 'new data path .mdf', MOVE 'log logical name' TO 'new log path.ldf';
Questions:
(1) If I specify the data and log file paths as ones that already exist, will they be overwritten? This is what I want, as I just want to copy the prod db over to the test server.
(2) Do I need to explicitly reset the DB back to multiuser mode, or does this happen after the restore?
(3) Anything missing from the above script(s) ? Suggestions?

(2) Do I need to explicitly reset the DB back to multiuser mode, or does this happen after the restore?
(3) Anything missing from the above script(s) ? Suggestions?
1.Just restore the backup with REPLACE command and it will overwrite the current database.
2.No , database will be automatically put to Multi user mode if you are restoring with recovery
3. Single user script is fine .Change restore script like no need to use with move option
restore database db_name from disk='location' with replace
Please mark this reply as the answer or vote as helpful, as appropriate, to make it useful for other readers
I think I will still need WITH MOVE, as the files in the backup are using a different path than where they are located on the test server, correct?
RESTORE DATABASE MyDBName
FROM DISK
WITH MOVE 'db logical name' TO 'new data path .mdf', MOVE 'log logical name' TO 'new log path.ldf' WITH
REPLACE;

Get a backup utility that does scheduled backups. There is no built-in backup facility in OS X except the Restore option of Disk Utility that does only full cloned backups.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

I had a software problem with my iPhone 4S and had to restore to factory settings. I had everything backed up on iCloud, but I was told not to restore using that backup. How do I get my photos back? I know it's on iCloud.

The Genius at the Apple Store restored my phone to factory settings. I had backed everything up on iCloud, but he recommended that I don't restore that old backup file since it might bring up the software issue again. I just want to get my photos back. Is there anyway to retrieve them from iCloud without having to restore my phone using my old backup? Or would I have to use the old backup, transfer my photos, and then do another factory restore? Help!

You would have to restore the backup, import the photos to your computer, then restore as new again.

Restore Tablespace incremental backup is not work as after reimage oracle

TheTablespace incremental backup Restore is not work as after reimage the oracle database or restore tablespace in standby machine(another machine) is not working .its working in the same machine without reimage .after reimage not working please clarify me ,
I need the solution as soon as please reply as soon as .
Commnads used:
This is the step is followed but i am getting backup or control file not found error.Its works i the application server is not reimaged ;
please give your valuable suggestion .
Product Used:oracle 11g in linux environmnet
1)Before taking backup get SCN number for restore.
Command applied: Select current_scn from v$database;
2)running Full backup of database

please calrfiy my following question:
1. After reimage(reinstall oracle database with application ).The aboove scenario is not working
2. After fullbackup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/) to repository because daily cleanup script will keep the data as sysdate -1 .
For fullbacckup we are currently copying entire (flash_recovery_area/dbname) database folder to repoistory.
3. after incremental backup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/..) to repository because daily cleanup script will keep the data as sysdate -1
For incremenatl backup currently we are copying (flash_recovery_area/dbname/backupset/<currentdate> and flash_recovery_area/dbname/autobackup/<currentdate>) folder to repoistory.
4.During restore we are copy entire things from repository to flash_recovery_area finaly apply the above mentioned restore command.
Tabelspace incremenatl restore is possible after reimage application server(fresh database)/another server with same database(standby machine) ....?
If we missing something in backup side please clarify me how to retore the tablespace incremental / level 0 tablespacae after reinstallion of server/another standby server.
Any information please let me know .I need the solution as soon as please reply as soon as .

Try the Recovery Manager (RMAN) instead. This forum is for feedback about the 11g XE Beta.

Anyone running Portal with NOARCHIVELOG mode in the Oracle DB?

Although we have several high-volume SQL Server customers running their DB in simple recovery mode (no transaction logging) with success, I am trying to determine if anyone is doing the equivalent with Oracle DB.
Even if you aren't using NOARCHIVELOG mode, please let me know your thoughts on performance, especially since the perception exists that the Portal is less performant on Oracle DB than on SQL Server. If that perception has any basis in reality, there should be an even greater potential for performance gain using Oracle DB, through intelligent tuning.
The cons of NOARCHIVELOG were pointed out to me by an excellent DBA:
1. Lose the ability to do hot online physically backup, (both RMAN and Manual)
2. Lose the ability to do point in time recovery of your database (irrelevant to the Portal)
3. When something bad happens to your DB, you are guaranteed to lose some data, because you can only recover to last good backup. (This is either acceptable to the business or not. Usually it is.)
Thanks for your thoughts!

There are no dumb questions. 'Better' or 'worse' can mean different things from different angles. I won't recommend something to a customer that I saw in an article somewhere, or gained knowledge via hearsay. I have to have tried it successfully with a customer, usually though iterative tuning, testing and monitoring cycles.
With that said, I see nothing wrong with using NOARCHIVELOG mode for the portal, and am looking to find someone with experience using it with the portal; and I don't mean a portal with four communities and a scant thousand users. I am looking for something more on the scale of our mutual customer who had about 15 front end portal servers, and about 15,000 hits per hour. Who, incidentally, is happily using SQL Server in simple recovery mode, and was game to try it out in the first place.

How to restore a older backup with a new SIM

Hi everyone!
I have a problem. I have a Iphone 4, which I bought with a contract in the UK. I recently went to a shop to unblock it (I live in France now)
Before I unlocked it I made a back up (i am new to this stuff) and now my phone is working with a new SIM card but when I do a back up from the Itunes, nothing comes back. I only see the apps that I downloaded in my Itunes, but no texts/emails/messages/photos. I made a newer back up/sync after that by mistake. But that wouldnt be a problem right? I can choose an older back up but it doesnt do much....
I tried it once before I dropped my phone at a shop to unlock it, and I could restore it but it took 3 hours so I cancelled. If I restore my backups now, it only takes a few seconds. So I think it is lost??
So somebody, please help me. I dont know what to do! I lost all my contacts etc...
Please...!
Cheers
Marie
