Block Media Recovery and RMAN Incremental Level 1 backup

Hi
I have read somewhere that Block Media Recovery will not work if a database is backed up using rman incremental 1. Is this true, and if so is there a work around?
I cannot seem to find this in oralce's documentation.
Regards
Me

Hi,
1) is Full Backup = Incremental level 0 backup?
Yes
2) When oralce say BMR does not work with incremental, will it work in the case I put forward. becuase Im doing an incremental 0...
But does you have the Archive logs available.. ?? If yes then it will Support.
3) Im my case will BMR work...that is use Incr level 0 on Sunday and then use archive logs for mon, tues etc
Yes, I believe.
@Hemanth .. am I right.. ?? Wait for your inputs...

Francois Degrelle.
just look the following code.
DECLARE

Item Level Recovery for 2003 VM's

Hello
I am having difficulty getting Item-Level-Recovery to work on System Center: Data Protection Manager 2012 R2. I am able to recover files on 2008 and 2012 virtual machines, but not 2003 virtual machines.
Things I've checked:
Checked 2003 VM's and made sure they are using basic NTFS disks and not dynamic
Applied 2012 R2 Update Rollup 4 to both DPM and Hyper-V hosts
DPM has protected the datasource as a Virtual Machine and not a folder
Ensured Symlink permissions are applied
Ensured SeManageVolumePrivilege permissions are applied
Error Experienced:
Description: DPM cannot browse the contents of the virtual machine on the protected computer <DPM Server Name>. Item level recovery is not supported in the following scenarios.
1. The VHD contains a dynamic disk inside the guest OS.
2. The VHD has no volume.
3. HyperV role is not installed on DPM server.
4. Automatic mounting of volumes is disabled on the DPM server.
1) Try enabling automatic mounting of volumes using mountvol on the DPM server to preform item level recovery.
2) Otherwise perform a full restore of the virtual machine.

Details: Internal error code: 0x80990F4E
Current Set-up:

Please can someone assist with finding the cause of this error, or could perhaps share some knowledge on how to go about resolving this.
Thank You

Change visual_attribute on current item at block level

Hello everybody.
Is there anyway to apply visual_attribute on current item at block level ? Explanation: i have block with a lot of items, so it's really hard to create many POST-TEXT-ITEM triggers on every item and apply visual_attribute on it...
Thx in advance.
Adnan
Edited by: adnanBIH on Dec 7, 2009 11:38 AM

Hi,
You can set the visual attribute using the following as per your requirement:
This is for item instance
Set_Item_Instance_Property( 'Your item', CURRENT_RECORD, VISUAL_ATTRIBUTE,'Custom_attribute'); for item
Set_Item_Property( 'Your item', VISUAL_ATTRIBUTE,'Custom_attribute'); regards

Block corruption recovery!!

Hi. all.
I am testing a recovery in the event of block corruption.
As far as I know, the solution to block corruption is as followings:
1. BlockRecover command (RMAN)
2. drop the table and import from backup dump file
3. DBMS_REPAIR package
4. complete recovery from online full backup
My question is whether No. 4 is possible or not.
step 1 : bring the datafile offline
step 2 : restore the datafile from the last backup(online backup)
step 3: recover the datafile, applying archive logs and online redo logs
step 4 : bring the datafile online
The above steps are enough for block corruption recovery?
I need to make a document about block corruption issue, but
I have no experience of recovering block corruption.
Thanks in advance.
Best Regards.

If few blocks are corrupted, it is advisable to run the BMR (block media recover, staring with 9i). This option provides the availability of other data present in datafile.
Option 4 is okay when most of the data block in a datafile got corrupted.
To know how many blocks got corrupted in the datafile, run the following:
SELECT * FROM V$DATABASE_BLOCK_CORRUPTION;
SELECT * FROM V$COPY_CORRUPTION;
SELECT * FROM V$BACKUP_CORRUPTION;
You need to look into corrution_type and blocks columns in the v$database_block_corruption view as it gives the reason for block corruption and number of blocks are corrupted in a datafile.

Block level changes on linux when a datafile is reduced by resize

Hi All,
Does anyone know what happens at the block level on Linux when an oracle datafile has its size reduced. For instance, if I have a 6gb datafile with has had the extents written to but the current HWM is 2gb and i then reduce this datafile size from 6gb to 2gb. On the file system the file is resized to 2gb but what actually happens to the blocks on the OS? The reason I am asking is because I am running Linux on vmware and the vmware file is replicated at the block level. How much additional data would be replicated if I reduced the datafile with a resize. Would it replicate the 4gb difference, or is only the end of the datafile changing and if so are only a few blocks changing. Oracle seems to reduce the file size quickly so I am assuming it is not changing many blocks. Any ideas?
cheers,
Matt

Hi Matt,
Are your datafiles on ASM? Raw? Filesystem?
I have not tested it, but I suspect that Oracle simply re-writes the extent map, whether that's in ASM, on the raw device, or on the filesystem.

HT3743 Unlocked 3G blocked in recovery mode

I have unlocked my old 3G phone and have used a Tmobile sim card successfully for over a year, but now the phone won't work and is blocked in recovery mode after I responded to an Apple update messages. Suggestions?

unlocked how? If it was not officially unlocked via the carrier the update has most likely locked it back to the original carrier.

How can we disable Block Level Trigge using Form Personalization

Hi,
I want to disable block level trigger(WHEN-NEW-RECORD-INSTANCE) using forms personalization at responsibility level.
Can any one please give me the answer.
it's urgent
Thanks and Regards,
Dhana

No, Firefox is user choice rules over the "wants" of individual websites as far as disabling contextual menus and the keyboard commands.
Placing a transparent image over the image will keep the less technical user from saving the main image. If they do try to save it all they'll get is the transparent image overlay.

Block media recovery

All,
I'm in the process of self-learning all kind of data recovery strategy on my desktop.
How to simulate the error of datafile block corruption ? To test the block media recovery through rman.
Please advice.
Thanks

Though in Windows, an open db doesnot allow a file to be openedYou should try with the most powerfull Win* tool: notepad...
You'll be surprised.

Form level Trigger Vs Block Level trigger

I have a form with single Database Block. I need to write a
transaction Trigger for this Block. I need to know r there any
advantages of writing the triggers at Form Level rather than at
Block Level.
Thanx in advance

Hello,
If you have to handle this stuff in more than one block, it seems more generic to put the code in a form-level trigger if you don't want to duplicate it several times.

Scrollbar on block level

Hello,
I'm trying to migrate a application from forms 4.5 to forms6i. If I want to run a form which has a scrollbar on the block level the runtime crashes down.
I could compile and generate the form without any errormessages.
It works if I set the scrollbar property on no. Does anybody know a solution for this problem?
Thanks,
Dirk

You can use a materialized view to ensure database integrity. Check for constraint violations in the MV when you commit the form.

Pre-insert block level, Seq.Nextval leaving gaps problem

Hi...form friends,
I used DB sequence in pre-insert block level trigger.
SELECT seq1.nextval INTO :abc.log_id FROM dual;
Everything works fine,except leaving gaps randomly .
It leaves around 10 no.s gaps in-between. And that happens randomly...
lets say I insert 5 records..then it will be 1,2,3,4,5.
Then it may jumps to 15,16,25 like...that....
I searched for this problem...but some say when form failure occurs, it leaves gap of CACHE no. specified....and some say its not possible to use DB seq. with forms perfectly ..!!!!
Anybody have any idea about this issue ???
Thanks....

Putting that functionality in a row level trigger will cause a mutating data exception.
Locking the table for update is not sufficient, you need to prevent other users inserting as well.
I've posted a method a few times before which uses dbms_lock and a table of serial numbers which is used in place of the oracle sequence. This provides maximum concurrency and allows for data to be rolled back, but there is obviously a payoff in terms of performance so it should only be used when absolutely necessary. There is a similar example in the link I posted above (which is a far more considered explanation than I've posted elsewhere!), along with some caveats about using gapless sequences and whether there is truly a need.
