Backup Mode and Error Checking

If I use RMAN why would I want to set the database to backup mode? Is there a way to monitor if RMAN fails or has errors? Can RMAN do compression?

RMAN does not require the database to be in "backup mode". That's one of the benefits of RMAN.
RMAN offers a LOG option that can be used to log RMAN's actions during it's operations. In addition to this log, several views exist that maintain corruption information (V$BACKUP_CORRUPTION, V$DATABASE_BLOCK_CORRUPTION and V$COPY_CORRUPTION). If you are using a recovery catalog, these views correspond to RC_BACKUP_CORRUPTION, RC_DATABASE_BLOCK_CORRUPTION and RC_COPY_CORRUPTION.
10g has RC_RMAN_STATUS & V$RMAN_STATUS and some additional views if you are using RMAN with OEM.

PIT recovery until time when database was in backup mode

Hello,
Is it possible to recover database until some point/time which is within "time window" when database tablespaces were still in online backup mode?
I was basicaly replicatying database from source to target DB by putting DB to online backup mode, then copy all datafiles, after copy of datafiles was finished I started applying redologs generated on source DB afterwards. After I applied tens of redologs with "recover database until cancel using backup controlfile" and then typed "CANCEL" after 10-20 redologs applied I still got an error that opening DB would get an error due to inconsistent datafile. When I ended backup mode on source DB and applied few of redologs after ending backup mode on source DB datafiles were consistent.....
Thx a lot for answer in advance.

Hello Hemant K Chitale ,
thats clear. I probably did not express it clearly, so I will describe it once again:
Teoreticall scenario 1:
I put 'source" database to backup mode and start copy datafiles to "target" db. When copy of all datafiles is succesfully finished (lets say it 5:00AM), I don't issue "end backup" on source DB but I keep tablespaces in backup mode until 7:00AM. On target DB I will start recovery and apply redologs from source system.
Question 1:Is it possible to recover database until time 6:00AM? At this time all datafiles were already succesfully copied, BUT source db was still in backup mode. Or will I be able to get target DB to consistent state only after 7:00AM (end backup issuied on source DB) and not in window 5:00AM-7:00AM?
Teoreticall scenario 2 (small correction comparing to scenario1):
I will put source DB to begin backup mode at 5:00AM on 20.february and let it in this state until 7:00AM on 20.february. On target DB I will restore backup from source DB performed day before (or few days before does not matter) that means on 19.february and start to apply redologs generated after this backup.
Question 2: Will I be able to recover DB until 6:00AM on 20.february and open database after recovery until this time? Or wont I be able to recover and open DB witin window 20.february 5:00AM-7:00AM (source db in backup mode)
Bear in mind this is just teoreticly (don't ask me why would you do it and why you don't do it this way etc...). I just want to understand how it really works ;)
Thx a lot!

Syntax/error checking breaks in FlexBuilder/Flashbuilder with class libraries over Samba?

We have our class libraries on a shared server we access via Samba (and ssh for command line). Sadly, several features seem to fail in both Flex Builder and Flash Builder/Gumbo with this setup. For example, we no longer get automatic syntax and error checking. Anyone familiar with this issue and able to suggest a solution? Thanks!

Be sure you are not mixing -compat=4 and -compat=5 compilations in the same program.
The -compat=4 mode is for compiling very old source code that was written for C++ 4.2 (1996). It provides almost none of the features of standard C++. Don't use this mode unless there is a specific reason why you must.
Do not use -I or -L options that point into /usr/include, /usr/lib, or into the compiler installation area. These directories are always searched by default in the correct order. If you specify them explicitly, you force an incorrect search order.
Be sure you have the minimum patch level of SUNWlibC required by the compiler. The patch includes libCstd, libCrun, libC, libiostream, libdemangle, and some other files. The minimum patch level comes with the compiler, and the Sun Studio installer will install the patch on the system where the compiler is installed.
You also need the patch on every system that runs the compiler, and every system that runs programs created by the compiler.
It is always safe to use the latest SUNWlibC patch. You can download the current patch from
http://developers.sun.com/sunstudio/downloads/patches/index.jsp
But the link failure in your case is due to a missing function from your own code, since it involves a function parameter of a programmer-defined type. I suspect you have either
1. failed to define (provide a body for) the function,
2. declared it inconsistently as inline and not inline,
3. defined the function in a namespace different from the one where it was declared, or
4. failed to link the object file where the function is defined.

Db corrupted in begin backup mode

hi all,
This is part of my practice only.
My db is 11.2.0.1.0 on linux. i kept my db in begin backup mode and started copy and forgot to end backup. taken controlfile backup like alter database backup controlfile to '/u01/app/oracle/orcl/control_bkp.ctl'.
Now i deleted all db files, redo files, control files corrupted. (to perform complete db recovery).
I started recovery. started in nomount and copied controlfiles from backup location to it's original location.
and then issued >recover database using backup controlfile until cancel;
given follwoing error.
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01195: online backup of file 1 need more recovery to be consistent
ORA-01110: data file 1: '/u04/oracle/oradata/jt10g/system01.dbf'
any suggestions please.
thanks for you help..

i can see from the link: https://forums.oracle.com/thread/634538 (MaranViswarayar replied) this type can't recovered. is it true.

Database in backup mode

Hi Guys,
If I put my database in backup mode and perform the backup (hotbackup/online) of the database.
When I need to do restoration, do I need any archive logs at all? (not necessary to recover up to point in time) Can i just restore the datafiles and do a alter database open resetlogs?
Will the database be inconsistent and can't startup without applying any archive logs at all? as the datatabase is not shutdown when doing the backup.
thanks

Will the database be inconsistent and can't startup without applying any archive logs at all? as the datatabase is not shutdown when doing the backup.Yep.
That said, use RMAN to do the same thing. It would be much better to use it than using the backup mode .

Blocking session in hot backup mode?

In 8.1.7.4 Some time While in hot backup mode, blocking session occuring by checkpoint session background process. Can we issue the alter system checkpoint command in this
Situation ? how to handle this?

best way is to try and see but checkpointing frequently wont help in my opinion, a better workaround may be ensuring you only place one tablepspace at a time in backup mode and bring the tablespace out of backup mode as soon as you have backed it up.

DB Taken out of Backup Mode During User-Managed Backup

I was taking a user-managed backup and the DB was accidentally taken out of backup mode in the middle of the backup. The backup continued and backed up all the datafiles, but many of the datafiles were backed up after backup mode was turned off. Can I restore the DB using this backup? What are my options?

The backup might be usable and it might not. When you put a tablespace (actually all data files in the tablespace) into backup mode, Oracle continues to perform writes to those data files. However, when first modifying a block in a data file after it has been put in backup mode, Oracle will put a before image of that entire block in the redo log (instead of just the row changes). After this first data block change is written to the redo log, further changes to this data block are written as just normal. Oracle does this initial write of the whole block to prevent fractured blocks during recovery. You see, when the OS copies the files for backup, it copies in chunks that might, or might not, fall on a data block boundary. A data block may be updated on disk between two OS file copy chunks. Thus when the file is restored it is possible that part of a data block will have new data and another part have old. This is a fractured block. When applying undo, Oracle first lays down a full block, which will cure a possible fractured block, and then apply redo as normal to complete the recovery operation.
This is why it is important to make sure that your hot backup set includes all redo generated between the time you put the tablespaces in backup mode and the time you took them out of backup mode.

Performance effect during HOT backup mode

Dear Experts,
Oracle 10gR2, Windows Server 2003 ,I.4TB database size
Our backup team put database in hot backup mode (alter tablespace begin......).
Is it cause some performance issue in the database ?
Thanks & Regards

Dear Aman,
As I told you I just joined and same thing I told to upper level, I need some definite proof so that I can prove my point because it always happens here: Database always put in hot backup mode and application here went very slow. I am a new DBA, so I need some some proof(what kind I don't know :)
Aman, hot backup with RMAN is more preferable as compare to alter tablespace begin backup...... command.
Why ?
and if so why we still using OS commands to take backup;
Thanks & Regards
Sunil Kumar
:)You have the answers to your other questions. As to "why we still using OS commands to take backup"? Well, um..... ;-) You'd have to ask you're organization that question. I can tell you there is no defensible reason to do so ..... ;-)
