RMAN Incremental Backups?
Sep 3, 2010"If no level 0 backup is available, then the behavior depends upon the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks changed since the file was created, and stores the results as a level 1 backup. In other words, the SCN at the time the incremental backup is taken is the file creation SCN. If compatibility <10.0.0, RMAN generates a level 0 backup of the file contents at the time of the backup, to be consistent with the behavior in previous releases."
So yes, that's it. Even in the Oracle 11g OCP course and exam, the information given is for Oracle 9 (pre 10g). Seems like a major functional regression.
------------------------------------------------------------------------------------------------------------------------------------------------
Original problem.
Am I not understanding something about rman????
Using oracle 10g standard edition and rman.
No existing backups.
When I run repeated level 1 cumulative incrementals, the appear to back up everything (like a level 0 would).
My understanding is that if a level 1 is run w/o an existing level 0 backup, it will generate a level 0 backup.
All subsequent level 1 backups should be level 1's as expected.
If I explicitly generate an level 0, followed by level 1's it all works as expected.
I am determining what got backed up by the size of the resulting save sets.
Do I have to do an explicit level 0 and then explicit level 1's? I thought not.
Incremental Statistics Gathering?
Sep 12, 2012 am having Oracle 9i RAC on IBM AIX .
I have large partitioned tables ( 4 partitions are added every month ). Is is possible to collect Incremental Statistics Gathering on these objects ( 9i ). If I collect stats with Ggranularity => ALL and ESTIMATE_PERCENT =100 the stats are accurate but it takes so much time .
One way may be to collect stats as Ggranularity => PARTITION for each new partition ( this quite fast ). but what about the Global Table Stats?
Full And Incremental RECOVERY WINDOW
Sep 5, 2010I have RMAN configured TO RECOVERY WINDOW OF 7 DAYS;I do a Level 0 backup on SAT, SUN-FRI I do a Level 1 (all to disk)
After I do a successful Level 0 backup, why would I need to keep Level 1 backups around on disk?I know the recovery window is 7 days but is there any way to remove the other 6 days of Level 1 backups after a successful Level 0?To me this seems like a waste of space since I have a succesful Level 0 or am I missing something?
Recovering Standby DB From Incremental Backup
Nov 11, 2010I've got a physical standby (10g) which is missing some archive logs, and thus the managed recovery is stuck. I followed the procedure for taking an incremental backup of the primary from the last SCN in the standby, and then recovering the standby from that backup using rman.
It seemed that everything went according to the instructions, except that the "recover database" of the standby from the backup went much faster than I expected. Afterwards I checked the SCN of the standby (select current_scn from v$database) and it had indeed updated to a number beyond where it was stuck originally. The standby controlfile was restored from a backup of the primary's current controlfile, and the standby restarted. The problem is that when I started up standby recovery again, the standby is still looking for the logs which were missing. I can't figure out why! I've been googling around and digging through the docs, and the only clues I can find suggest that this would happen if the standby controlfile wasn't updated. But I did that.
RMAN :: Incremental Backup - Archive Log?
Jun 6, 2012We are going to implement oracle 11g. Now I wanna use rman to take the incremental backup in the follwing way:
Level-0 backup weekly, in the way:
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
BACKUP incremental level 0 DATABASE
TAG 'Weekly_full' FORMAT 'E:RMAN_backupweekly_full_%d_%Y%M%D_s%s_p%p.bak';
backup archivelog all not backed up 1 times delete input
TAG 'Weekly_full_arc' FORMAT 'E:RMAN_backupweekly_full_arc_%d_%Y%M%D_s%s_p%p.bak';
[code].....
and RETENTION POLICY TO RECOVERY WINDOW is set to 10 days, so that there is no chance that i will delete expired backup before taking backup.
Now my question is,
1) Is the way is correct that there is no wrong configuration. My main concern is about archive log, is it correct?
2) As i am deleting archive log files with the backup and after that the expired archive log backup is also deleted, so is there any chance of failure in recovery.
3) here how archive log backup will work with 10 days retention policy.
RMAN :: Manage Incremental Backups?
Feb 15, 2013We just purchased NAS (Raid5) unit to manage our data storage. I am planning to create a virtual partition on this nas device and use one partition for oracle data storage and another virtual partition will be used by other data (files and may be sqlserver data files....etc..)
We will have oracle installed on seperate oracle server. Can we use RMAN to manage incremental backups in this environment? May main worry point is that our data storage device will have many different type of datas and will we be able to tell RMAN to make backups only from certain virtual drives?

RMAN :: How To Move Datafile Copies From Incremental Backup
May 17, 2013As part of an incremental backup I recover copies of the tablespaces. These by default are stored in the disk backup location diskgroup. Is it possible to move these copies to another disk group / location whilst still backing up to the default disk backup location diskgroup. I know how to do it with the main datafiles but not with the copies.
e.g.
Current situation:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +FRA
New setup to be:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +BACKUP

In the execution plan of STEP-3, against ID-1 the operation RESULT CACHE is shown which shows the result has been retrieved directly from Result cache. Does this mean that Oracle Server has Incrementally Retrieved the resultset?
Because, before the execution of STEP-2, the cache contained only 2 records. Then 1 record was inserted but after STEP-3, a total of 3 records was returned from cache. Does this mean that newly inserted row is retrieved from database and merged to the cached result of STEP-1?
If Oracle server has incrementally retrieved and merged newly inserted record, what mechanism is being used by the Oracle to do so?
Oracle Database Concepts 11gr2 - Incremental Checkpoints Behavior?
May 3, 2012Oracle database concepts 11gr2 manual states that "An incremental checkpoint is a type of thread checkpoint partly intended to avoid writing large numbers of blocks at online redo log switches. DBWn checks at least every three seconds to determine whether it has work to do. When DBWn writes dirty buffers, it advances the checkpoint position, causing CKPT to write the checkpoint position to the control file, but not to the data file headers."
As i have understand the DBWR write DIRTY BUFFER (that are under active checkpoint requests in the ACQ) to the datafiles from The Buffer Checkpoint Queues and after that the CKPT process may write the checkpoint RBA to the control files.[URL]...
The CKPT porcess write the chekpoint RBA to the controlfile after that the DBWR write the Dirty BUFFER in the datafiles, so as i understand at some point the datafiles containt block with higher RBA than the controle files. am i wrong ?
So if the instance craches before the CKPT record the chekpoint RBA in the controlfile what will be the recover behavior.Will the redo record be reapplied from the last recoded chekpoint RBA in the controlfile to the tail of the log ?
