How does recovery work after an online backup

Hello,
While trying to conceptually understand how backup and recovery works, I came accross a question concerning hot (online) backup.
This is a conceptual question (I am trying to understand how things work), it is not a "how should I proceed/ what should I do step by step" question.
As far as I understand, an online backup of a tablespace can be performed by copying the OS files making up a tablespace while the database is up and being used (i.e. transactions are modifying data in the database). Before the copying of the OS files starts, the Oracle RDMS must be notified that an online backup is being taken via "ALTER...BEGIN BACKUP" (such that some additional information is written to the Redo Log, which may be required for subsequent recovery using the online backup). During recovery the Oracle RDBMS uses the copies of the OS files together with the online and archived redo logs in order to reconstruct all committed transactions and it further uses the UNDO tablespace to rollback open (uncommitted) transactions.
Thinking about this, it seems to me, that in order for this to work in all possible scenarios the undo information from the time the backup was taken may be required. Therefore backup of the UNDO tablespace should be taken as well (see the explanation for this assumption below). However browsing the internet (including the Oracle online documentation) I did not find any statements concerning the backup of the UNDO tablespace when an online backup is taken. Moreover I couldn't figure out when exactly such a backup of the UNDO tablespace must be done, to ensure that the database can be recovered in all scenarios.
I believe that undo information from the time the hot backup was taken may be required e.g. in the following scenario:
Assume we are taking a hot backup of a given tablespace, i.e. we are copying all OS files that make up this tablespace, while the database is potentially being used. Let D1 be one of the datafiles in our tablespace and let transaction T1 modify datafile D1. Let transaction T1 further be uncommitted while the copy of datafile D1 is being made and let (at least some of) the changes from T1 be included in the backup copy D1' of D1 (because DBWR has already written the modified blocks at the time they were being copied to the backup). Let transaction T1 be rolled back after the copy is completed. D1' will thus contain modifications from T1, while D1 will not.
Now some time later the datafile D1 is lost. When recovering D1 from the copy D1', the (archived) redo logs will be applied to D1'. Before that, transaction T1 should be rolled back in the copy D1', because modifications from T1 must not appear in the recovered version of the database.
I do however not understand, where the information to rollback transaction T1 exactly comes from. It may still be in the current UNDO tablespace. I do however assume that rollback information is not kept in the UNDO tablespace forever. I see three possible answers to this
(a) There are some requirements which I missed so far to backup the UNDO tablespace whenever a hot backup is made.
(b) Since the Oracle "RDBMS" has to be notified that an online backup is being done, it might store all relevant undo information (e.g. write it to the redo log) when the tablespace is put in backup mode.
(c) There are situations when recovery is not possible due to "missing old UNDO information".
Answer (b) seems the most plausible to me. I did however not find any confirmation of this and if (b) really is the answer, I would be interested to understand what information is stored where by the Oracle RDMBS and how it is used for recovery.
To summarize I have the following questions:
(I) Is there any requirement to backup the UNDO tablespace together with an online backup of a tablespace, and if so, where is this stated in the Oracle documentation?
(II) What mechanisms ensure that uncommitted transactions can be cleared from the online copy of a tablespace (potentially a long time after the copy was taken)?
(III) Do you know any links (Oracle documentation or other online resources) explaining these datails?
Thank you for any hints and answers
kind regards

Its a highly technical question and I can be completely wrong due to my very less knowledge but I would attempt to answer still. Hope I say something sensible so bear with me.
As far as I understand, an online backup of a tablespace can be performed by copying the OS files making up a tablespace while the database is up and being used (i.e. transactions are modifying data in the database).Correct. But it would depend on the tool you are going to use to do so.Using o/s level commands like CP and all would require you to manually copy the files to the backup location. Using RMAN, it would be lot easier and RMAN would take care of everything.
Before the copying of the OS files starts, the Oracle RDMS must be notified that an online backup is being taken via "ALTER...BEGIN BACKUP" (such that some additional information is written to the Redo Log, which may be required for subsequent recovery using the online backup). Again, this is a requirement only in the case of user-managed backup . In that case, because of the fractured block issue , its important that the corresponding older information/image of the buffer is also copied in the redo stream and that's done when the begin backup command is used. Using RMAN, this is not needed as RMAN can read the consistent image which it would store in the backup piece, exactly in the same way in which select request is fulfilled by oracle for a dirty buffer which is yet to be made consistent.
During recovery the Oracle RDBMS uses the copies of the OS files together with the online and archived redo logs in order to reconstruct all committed transactions and it further uses the UNDO tablespace to rollback open (uncommitted) transactions.Correct!
Thinking about this, it seems to me, that in order for this to work in all possible scenarios the undo information from the time the backup was >taken may be required. Therefore backup of the UNDO tablespace should be taken as well (see the explanation for this assumption below). >However browsing the internet (including the Oracle online documentation) I did not find any statements concerning the backup of the UNDO >tablespace when an online backup is taken. Moreover I couldn't figure out when exactly such a backup of the UNDO tablespace must be done, to >ensure that the database can be recovered in all scenarios.The reason that its not a must to do so is that if the transaction is yet active, there is no way that Oracle would overwrite the Undo information of it, even if you may come after 100 years, it would be there. The Undo segment would mark those blocks as active undo blockswhich contains the information of that transaction whose status within the transacton table of that undo segment is still marked as active. So its there all the time in the undo tablespace. Now, for an instance, let's assume that the undo is not there as well( it would be but let's assume), the changes made to the undo segment's blocks are also recored in the redo as its just a change happening to any other segment like EMP,DEPT except with the difference that its not done by you but by oracle. So using that information, in the future , if there would be a need to replay those changes, necessary information to do so can be brought up from the redo blocks stored in the redo/archive logs. Yes, if there would be pending transactions that would require Undo information to get them rolled back and you have lost Undo tablespace and have no backup of it , you wont be able to bring back the database as it would be inconsistent and oracle would not let you to do it. In that case, you may require to use hacks to get it up and that would be really tricky situation.
(I) Is there any requirement to backup the UNDO tablespace together with an online backup of a tablespace, and if so, where is this stated in the Oracle documentation?As I said above, it must be there if you are anticipating loss of Undo tablespace. If you have lost it, you would need a backup and all the archive logs and redo logs to recover and get it back to the point where the current database is . Rest, oracle would take care as it would reapply the redo contents of the undo segments over the undo segment and get it consitent.
(II) What mechanisms ensure that uncommitted transactions can be cleared from the online copy of a tablespace (potentially a long time after the copy was taken)?As I said , pending transaction's undo is never overwritten by Oracle. Its always kept and marked as active undo . Only a transaction end would make it elgible to get overwritten and that too won't happen immediately(undo_retention would kick in) .
(III) Do you know any links (Oracle documentation or other online resources) explaining these datails?I have to see if its there some where step by step mentioned and I shall update the reply once I shall find the link. Hoep someone else in the meantime finds it .

How do i get rid of the charge on my debit card for online backup?

how do i get rid of the charge on my debit card for toshiba online backup? Backup has not been functional for months. I called the customer service number and eventually was transfered to some apartment complex phone number.

Hi there!
You cal to customer services of your bank or credit card and being told as disenroll in Argentina is usually effective.
Another way is Toshiba customer that you want to cancel the service, it is your right.
Because you have hired an online backup service with so many free payment? On the other side is always better physical backup, at least I think so.
Best regards.

No Online backups due to datafiles offline than I canu0092t recover. How...?

Hi gurus!!!
I got into a problem with some datafiles.
We have MySAP in a BD oracle 9.2.0.6
I used Oracle Entreprise Manager Console to generate two datafiles in the tablespace PSAPPRDUSR,
but I generated them in another tablesapce (PSAPPRD) with a name of file,
size and location very different from those that there uses the tablespace PSAPPRD.
So... I put them offline later to erase them later!!!
The datafiles contains no data.
Later, in the night backup:
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2 is RECOVER
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2a is RECOVER
 BR0301E SQL error -1128 at location BrTspAlter-3
 ORA-01128: cannot start online backup - file 31 is offline
 ORA-01110: data file 31: '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
 BR0280I BRBACKUP time stamp: 2007-04-20 03.01.21
 BR0316E 'Alter tablespace PSAPPRD begin backup' failed
 BR0056I End of database backup: bdvbtndh.ant 2007-04-20 03.01.21

And now... I neither can erase them nor can put online again.
To erase them I used:
SQL> ALTER DATABASE DATAFILE '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2' OFFLINE DROP;
Database altered.
SQL> commit;
But they continue there, do not resign.
To put them online:
SQL> alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2';
alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
ERROR at line 1:

ORA-00280: change 31203204 for thread 1 is in sequence #2574
SQL>
But we have continued working and I don't want to lose any data.
HEEEELP!!!!
What I can do to recover the datafiles and to continue with my daily Online backups?
The BD is in production and I do not have long time to fix it, only a few hours on Saturdays night.

Hi,
alter database datafile offline drop;
This command is not meant to drop a datafile. It is meant to offline the datafile with the intention of dropping the tablespace.
For a tablespace comprising multiple datafiles you can only drop a datafile by dropping the entire tablespace, this will work even you have one datafile.
If you have 10gr2, it's finally possible to drop a datafile as long as
it's not the only datafile within the tablespace, and
the tablespace is only and in read-write status.
So since you are on 9i your situation in summary:
If you have more than one datafile in the tablespace and you wish to keep the objects that reside in the other datafile(s) which are part of this tablespace, then you must export all the objects inside the tablespace.
1. Gather information on the current datafiles within the tablespace by running some query to remember the t/s, segment, and datafile info.
2. Export all the objects that you wish to keep.
3. Once the export is done, issue the DROP TABLESPACE <tablespace name> INCLUDING CONTENTS.
4. Delete the datafiles belonging to this tablespace using the operating system.
5. Recreate the tablespace with the datafile(s) desired, then import the objects into that tablespace.
Hope this helps and good luck,
George

Whole Database Online + redo log backup: How Long?

Hi gurus,
There's something I want to ask about online backup with redo log.
If i'm correct, redo log file is created everytime there's operation that change datafile right?
If i schedule this type of backup everyday, it means it will backup all datafiles, along with redo log file when transaction take places, at my pre-defined hours, right?
Then here's what i'm confused about. When will this backup process finished? Is it when all the datafiles have been backed up? Then how about the redo log files? If there are users that keep making transaction (therefore make change to datafiles), new redo log files will be created on disk, and that will prevent the backup process to finish. Then when will this cycle come to an end?
Please confirm if my grasp about oracle online backup is correct or not, and provide explanation to satisfy my curiousity.
Thanks gurus,

Hello Fidel,
i am feeling honored
> Keep in mind that the only thing where a DBA cannot make mistakes is restore/recovery and this depends on your backups
In general i would say you are right, but i have seen already one case where this statement is not true.
Some time ago i got a call from a colleague where his database crashed, the online redolog files were corrupted and the recovery was not working.
If you don't look really close at this point you are in trouble and can not continue the recovery. Let explain this on a example.
This demonstration is done on an oracle 10.2.0.4, but it work on every other version too.
Let's simulate a crash
SQL> shutdown abort;
Corrupt/delete a specifc redolog file
SQL> startup
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
ORA-27037: unable to obtain file status
Ok - so far so good, lets check the groups and files
SQL> select GROUP#, STATUS, MEMBER from v$logfile where TYPE = 'ONLINE';
 GROUP# STATUS MEMBER
 1 /oracle/TST/oradata/redolog/redo01.log
 2 /oracle/TST/oradata/redolog/redo02.log
 3 /oracle/TST/oradata/redolog/redo03.log
SQL> select * from v$log;
 GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
 1 1 95 52428800 1 NO CURRENT 5117817 06-JAN-09
 3 1 94 52428800 1 YES ACTIVE 5117814 06-JAN-09
 2 1 93 52428800 1 YES ACTIVE 5112855 15-DEC-08
What's the situation?
The online redolog file of group 3 is lost/corrupted and this group is needed to perform a complete recovery (see status ACTIVE).
But you are lucky, because of this group 3 is already archived - so you can perform a complete recovery.
Now let's perform a complete recovery but with UNTIL clause (because we need to jump between the online and archived redologfiles)
SQL> recover database until cancel;
ORA-00279: change 5116194 generated at 01/06/2009 21:06:48 needed for thread 1
ORA-00289: suggestion : /oracle/TST/oraarch/TST_1_93_6b8c0516_666969185.arc

ORA-00279: change 5117814 generated at 01/06/2009 21:08:47 needed for thread 1

ORA-00278: log file '/oracle/TST/oraarch/TST_1_93_6b8c0516_666969185.arc' no longer needed for this recovery

ORA-00278: log file '/oracle/TST/oraarch/TST_1_94_6b8c0516_666969185.arc' no longer needed for this recovery
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
/oracle/TST/oradata/redolog/redo01.log
Log applied.
Media recovery complete.
Now execute an OPEN NORESETLOGS accidentally (maybe the dba think it is not necessary because of the complete recovery) and try an OPEN RESETLOGS after:
SQL> alter database open noresetlogs;
alter database open noresetlogs
ERROR at line 1:
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
ORA-27037: unable to obtain file status
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery
So now you are lost.. you can't execute an UNTIL CANCEL anymore which would be needed to perform a successful OPEN RESETLOGS.
In this special case you can do mistakes and you have to restore the whole database and perform the same recovery again and end with OPEN RESETLOGS.
Just for information
Regards
Stefan

How RMAN do online backup?

When doing RMAN online backup, all datafiles are not in backup mode( not like user managed backup). How oracle did that? multifiles backup at same time without redo and undo.
Thanks.

From Article Note:76736.1 RMAN FAQ: Recovery Manager -- Frequently Asked
To understand why RMAN does not require extra logging or backup mode,
you must first understand why those features are required for non-RMAN
online backups.
A non-RMAN online backup consists of a non-Oracle tool, such as cp or
dd, backing up a datafile at the same time that DBWR is updating the
file. We can't prevent the tool from reading a particular block at the
exact same time that DBWR is updating that block. When that happens,
the non-Oracle tool might read a block in a half-updated state, so that
the block which is copied to the backup media might only have been
updated in its first half, while the second half contains older data.
This is called a "fractured block". If this backup needs to be restored
later, and that block needs to be recovered, recovery will fail because
that block is not usable.
The 'alter tablespace begin backup' command is our solution for the
fractured block problem. When a tablespace is in backup mode, and a
change is made to a data block, instead of logging just the changed
bytes to the redo log, we also log a copy of the entire block image
before the change, so that we can reconstruct this block if media
recovery finds that this block was fractured. That block image logging
is what causes extra redo to be generated while files are in backup
mode.
The reason that RMAN does not require extra logging is that it
guarantees that it will never back up a fractured block. We can make
that guarantee because we know the format of Oracle data blocks, and we
verify that each block that we read is complete before we copy it to the
backup. If we read a fractured block, we read the block again to obtain
a complete block before backing it up. non-Oracle tools are not able to
do the same thing because they do not know how to verify the contents of
an Oracle data block.
Backup mode has another effect, which is to 'freeze' the checkpoint in
the header of the file until the file is removed from backup mode.
We do this because we cannot guarantee that the third-party backup
tool will copy the file header prior to copying the data blocks.
RMAN does not need to freeze the file header checkpoint because we
know the order in which we will read the blocks, which enables us to
capture a known good checkpoint for the file.

How to use online backup services with a Mac.

I want to use an online backup service but each one I check out is unable to backup at least one of my key files and perhaps others that I havent tested yet.
I use an old palm pda and a current version of the palm desktop for mac. I'm quite happy with it and have tons of info on it.
But the online backup services store the files on an IBM server and when I restore it to my Macbook I get a Unix. exe file that I cannot use. I cant even import it or open it on a pc (which would be an acceptable solution in case of an emergency).
I really need a good backup solution for all my Mac files.
I've spoke to Apple, Palm and the techs at the online backup services and no one has a solution.
Any ideas would be appreciated.

You are very welcome. I don't think you can do scheduled updates. Apparently what happens is that the update happens whenever anything is changed on the desktop iDisk. No you don't have to recreate the desktop iDisk ever. That is, you can leave it on your desktop continuously. I trashed mine because I don't like to have things working in the background if I don't currently need them. On the other hand if I changed many things in a day, then I'd leave it on the desktop continuously.
If you check out all the MobileMe features, then you might decide that you like it. Your Dock mail program mirrors exactly what is on the MobileMe online mail program. I have to admit that the online program is very slow. But, the on Dock program more than makes up for the deficiency. Back to Mac is a cool feature. And, the online photo album feature is very easy and works well, except that it doesn't seem able to handle animated gifs.

What is the best online backup for OS 10.5.8? And if I Reinstall OS will I have problems?

My old Mac has had the flashing question mark file on a blue screen. I waited a couple days, turned it back on and it worked. However, in between that time I went and bought a new Macbook Air. I am relieved to have all of my pics and docs back. I need a good online backup. I downloaded BackBlaze Backup but it is taking forever and I am not sure if it's the best choice.
My plan is to backup all of my files and then wipe my computer clean with the install disks and give my computer to my little sister. So, my question is two fold; which is best online backup and will I have any issues wiping clean the computer and doing a reinstall? For example, will all the updates still be available? What is the best thing for me to do?
Thank you : )

Just understand it gets pretty expensive after you exceed the free space. 2-5 GBs isn't much space.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
     used to manage backups and to restore backups. Time Machine
     requires a backup drive that is at least twice the capacity of the
     drive being backed up.
3. Time Machine requires a backup drive that is at least double the
     capacity of the drive(s) it backs up.
Alternatively, get an external 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. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
1. Cool Drives
2. OWC
3. WiebeTech
4. Firewire Direct
5. California Drives
6. NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

AIR Sqlite can support online backup from memory to disk??

like this link:
http://www.sqlite.org/backup.html
how can i online backup my Sqlite dataBase from memory to disk?

You will need to remove the internal storage from that 2010-11 MBA, and put it in an external USB3 enclosure for use with a 2014 MBA. The assumption here is that the logic board failure did not corrupt the internal storage contents.

April 2015 Pricing change for Azure Online Backup questions

The webpage for Azure Online Backup pricing indicates that for protected devices over 5GB/month there will be a new model (i.e. free workloads are still free).
It indicates that its $10 per instance protected in 500GB blocks + storage.
The functional thing about azure online backup was the predicable model - As long as I monitored storage I knew what I would be paying since all other costs were included. The "+ storage" doesn't really give me any idea what will be billed.
Now the question is how complex is it?
What is the storage type? Blob? Page Blob/Disk?
What is the geo status? LRS, ZRS? GRS?
Do I pay for ingress, egress? Express-Route traffic?
Is there storage transaction fees?
The pricing web page really needs to provide a more complete set of info that what is currently there.
thanks!

Online backup recommendations for Aperture 3?

I'm interested in an online backup for just my Aperture library and would like to know if anyone has a recommendation and how it works. I have a vault archived to an external hard drive, and don't know, because of the way Aperture 3's library is stored, if I can do it easily or not. My library is only around 20GB right now, and would like to find a way do to incremental backups online, after the initial backup. I've heard about Crashplan, Mozy, Carbonite, Smugmug, etc., but don't know how to find a good one without wasting time. Thanks.

Referenced vs. managed should make no difference to a backup solution because a managed Aperture library isn't actually a file; it's a directory. It only has the illusion of being a single file when viewed in Finder.
An incremental backup solution can't actually tell the difference. The only reason Finder knows is because Apple puts an extended attribute on the directory node which flags Finder to not display it as a normal directory (but it is a normal directory). But any other software not programmed to check for this special flag would never know to treat the library any differently than it would treat any other directory hierarchy.
BTW, although you can descend into the Aperture Library and snoop around, you should NOT change anything. This can cause corruption as Aperture also maintains indexes & meta-data inside the library which it updates accordingly whenever it makes a change. If you were to manually make a change, you wouldn't also be able to update the appropriate meta-data and that will cause problems.

Open resetlogs is not working when creating clone db with online backup

Hi All,
I am trying to create a clone database using hot backup of a database .
STEPS THAT I FOLLOWED
LET ----- >CURRENT_DB NAME=DEV
CLONE DATABASE NAME=DEVCLONE
steps PERFORMED FORM DEV DB
- put the database in backup mode using 'alter database begin backup'
- copy all the data files to a different folder
- during copy i have performed some operations on the DB (creating users, tables, dmls etc...)
- in between copying i also performed log switch
- after completion of copy , "alter database end backup"
- created a backup control file in a human readable format (alter database backup controlfile to trace as ........)
steps performed for clone DB side ((DEVCLONE)
- created a parameter file for the database .
- modified the backup control file so that it will point to the location of copied destination of datafiles
- set the ORACLE_SID
- then 'sqlplus / as sysdba
- starup nomount
- run the modified control file ( created a control file for the clone database)
- recover the database using "recover database using backup controlfile"
I have provided the archive files that it was asking for (archive logs that has been generated in DEV DB)
then i canceled the recovery by typing "cancel"
- recover database using backup controlfile until cancel;
then typed "cancel"
- then try to open the database with open resetlogs but it showed below error
alter database open resetlogs
ERROR at line 1:
ORA-01195: online backup of file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'D:\DATA_GUARD\DEVHOT\SYSTEM01.DBF'
please help me on this ......
Thanks

Thanks , now i am able to open the DB in open reset logs mode .
Previously , when i had not taken the archive log after "alter database end backup" , i was not able to open the db with open resetlogs because the
fuzzy status of all the datafile headers were YES .
But after taking the archive log that got generated after "alter database end backup" and applying it on the clone db(Created with HOT backup ) the datafile_header status got changed from YES to NO .
So for that i am able to open the clone db with open resetlogs .
Can you please help me with a small description why this is happening ?
Thanks.......
