DataGuard: MRP still in WAIT_FOR_GAP after incremental backup recover
Hello
I'm new to the dataguard configuration, and recently, I connected on a dataguard configuration to test the object.
I have deleted stupidely some archive my primary database logs, thereby breaking the standby update (due to the fact that the database has not been started for a long time, the gap is now about 130 days ).
I have to try to recover the situation re-synchronized the RCS of the day before using an incremental backup (and create eve of primary control files).
After restoration, the SNA were the same, but restarting the recovery service (MRP), it is still indicating WAIT_FOR_GAP and still waiting for my missing archive logs.
New archive logs is well shipped to the waiting however.
No idea what I missed or what should I do?
The database version is a 12.1.0.1.

Problem solved.
In Oracle 12 c, roll forward is more to do "by hand".
There are a few commands to RMAN done automatically, by using the primary database service (G12DGGOP_DG for me).
So back up mode:
RESTORE DATABASE SERVICE G12DGGOP_DG WITH THE HELP OF NOREDO COMPRESSED BACKUPSET SECTION SIZE 100M;
Then after restore controlfile in nomount (stop):
RESTORE CONTROLFILE EVE OF SERVICE G12DGGOP_DG;
The information comes from here:
http://allthingsoracle.com/rolling-forward-a-physical-standby-database-using-the-recover-command/

"""""Hi Robert,.
Can you please try reconfigure the incremental backup. I think that according to the logic, the incremental backup is forced OFF mode when an error has occurred during one of the previous incremental backups. If you still see the same error after re-set up, I would say you can check this problem with TAC, as it is something related to the data are saved.

Incremental backup gives error on Standby Database.
Dear all,
I configured the RMAN scripts for full and incrementak on primary and standby. Full backup for his works very well on both sides, I'm me following error on the database waiting for incremental backups.
ORA-19648: datafile 1: incremental YVERT of start is equal to checkpoint YVERT
ORA-19640: datafile checkpoint is YVERT 1150604773 11/03/2015 time 08:14:57
Database version: 11.2.0.1.0
Configured Active DataGuard.
OS: RHEL - 5.5
I also observed that when I cancel the MRP process (using command, below) and run the backup script incremental standby it works fine without error.
(Alter basic managed recovery sleep cancel;)
Please suggest for the resolution of it.
Kind regards
Ronak Masudi
You primary and stanndby are synchronized. ? Since

DataFile checkpoint is SNA time string
Cause: This message identifies the control point data file for a data file that was too old to take an incremental backup, or the target of a gradual restoration, which could not be applied.

Is slow makes differential incremental backup restore?
DB version: 11.2
Platform: Unix/Unix
Lets say we have a 1 TB database and we have 2 GB of change every day.
For a differential incremental backup
For a cumulative incremental backup, all changes Sunday will be saved for each LEVEL 1 runSunday --> Level 0 backup Monday --> Level 1 backup --------> Monday's Backup piece size of 2gb Tuesday--> Level 1 backup --------> Tuesday's Backup piece size of 2gb Wednesday--> Level 1 backup --------> Wednesday's Backup piece size of 2gb Thursday--> Level 1 backup --------> Thursday's Backup piece size of 2gb Friday--> Level 1 backup --------> Friday's Backup piece size of 2gb Saturday--> Level 1 backup --------> Saturday's Backup piece size of 2gb
Lets say after the backup of LEVEL 1 of Friday (incremental or cumulative), we want to restore from a backup.Sunday --> Level 0 backup Monday --> Level 1 backup --------> Monday's Backup piece size of 2gb Tuesday--> Level 1 backup --------> Tuesday's Backup piece size of 4gb (monday + tuesday) Wednesday--> Level 1 backup --------> Wednesday's Backup piece size of 6gb (monday + tuesday + Wednesday) Thursday--> Level 1 backup --------> Thursday's Backup piece size of 8gb (monday + tuesday + Wednesday+Thursday) Friday--> Level 1 backup --------> Friday's Backup piece size of 10gb . Saturday--> Level 1 backup --------> Saturday's Backup piece size of 12gb .
For the award of
================
RMAN will take backup of level 0 Sunday and apply all differential incremental backups (2 GB) until Friday.
For Cumulative
================
RMAN will take the level 0 of the Sunday backup and apply the latest cumulative backup taken on Friday (10 GB).
The only delay (if any) for the restoration of the differential backup is that RMAN should check all elements of backup that was created after the Sunday level 0. But y at - he's going to be a noticeable delay for RMAN in the follow-up of these elements of backup? Just search the catalog to find who are the backup items created by LEVEL 1 runs after Sunday LEVEL 0. This should take only milliseconds. Right?Identify the backuppieces may not take a lot of time (However if you have a lot of data files and the data files by backupset, you would still have much backupsets every day!)
But if from your backups on tape, restore each day may have to be reading a different tape - library will pass some time 'mix tapes'.

Incremental backup PES 9 catalog does not
Hello
I tried to do an incremental backup of my catalog and it did not work.
Recovery I did a full backup and everything was ok. Today, I tried to do an incremental backup and theoretically he finished ok but when I looked at the folder where the backup was recorded, the size is the same and the number of cases neither.
Until the record was 100 GB and 15529 files. 163 files have been added and after the differential backkup finished size and the number of files remained the same.
PES 9 displays no error message.
Someone has an idea to solve this?
Kind regards
PS - I have aprox. 300 GB of free space in the backup location.
luismgh wrote:
It makes sense but why PSE 9 does not say where will the incremental backup will be saved?
I think you are right in the meantime the Organizer to guide you and ask you to create a new folder. However, people still use DVD or CD as well as other drives, internal or external. And to achieve good backups, you must first understand what a catalog: a folder that contains the database and associated files and subdirectories. It is difficult to explain the backup stream if you do not understand how catalogs and backup are stored. The choice to create a new folder somewhere on a DVD or an external drive can hardly be suggested by a default setting in the Organizer...
I gave up using incremental backups, mainly because I can't find them no faster than full backups, and I find them less reliable.

Backup and restore in Windows 7 will not make an incremental backup
Hello.
I have about 400 GB of backup files, for most audio (I have a home studio). Backup and restoration continues to do a new backup full instead of an incremental backup. I tried to disable "Windows Media Sharing whatever" and has no effect. I found the registry entry that the so-called forces a backup under certain circumstances, if I understand correctly. I put the value '0' and he still makes no difference - copy Windows files that I know have not changed over the YEARS and to create a new full backup. My current full backup is December 2014 on a 1 TB external hard drive. It is the backup that I added to-probably on a maximum of 20 additional concerts.
This is important because in 400 concerts, I have neither the time nor the space to do a full backup every time. I searched these forums and around the web and found nothing more disable sharing of Windows Media Services. For now I'm reduced to manually copy the new audio files on a backup drive, which is heavy at least when dealing with the whims of my Audio sequencer for recording methods and organization of files.
Please let me know how I can make an incremental backup instead of a full backup of my hard drive. Thanks for your help.

IMHO, I wouldn't play with the built-in backup. It is, at best, kludgy, depends on the OS partition, is inflexible and not easy to use.
IMHO, I would not trust my data or spend my time on it.

How incremental backup does know what files are modified.
I had this question in school. This time Google does not know the answer.
I hope someone can help.Probably tell you incremental backup?
When a file is saved its file properties are changed.
If a file is replaced with a new one, the file properties are still once changed

Hi all
I have a question, I am on RHEL-6 / Oracle 11 GR 2.
After taking the backup of level 0 (RMAN), if I plan tale level1 backup then how oracle knows that they are the backup piece is considered a level 1 backup.
I mean, that's how oracle knows that these are the blocks that had to be backeup.
Kind regards.

Hello
I'm nologging operations + deleting some files in the primary and you want to roll forward the day before using the incremental backup Yvert.
I do in particular, as the files are dropped?
I got to meet ( Doc ID 1531031.1 ) which explains how to roll forward when a data file is added.
If I follow the same steps, to make the move to restore the data file newly added, will it work in my case?
Can someone please clarify?
Thank you

I was wondering if reocover noredo is performed before restored controlfile, oracle will apply the incremental backup error-free files, and in this case, what would be the status of the data file in the control file.
Why do you consider to retrieve the day before first and then in the restaurant of the controlfile will lead to problems. Please read my first post on this thread - I had clearly mentioned that you would not face problems if you go with the method of deployment.
Here is a demo for you with force logging is disabled. For the first time the day before resuming and restored then the controlfile ensures:

Hi, I have always used backups RMAN and tested and restored several times without problem.IM now playing with incremental backups and seem to get confused.
I ran a level 0 backup, then a level 1 backup and then deleted some db files and restored my database very well. However when I sailed on the recovery, I expected to pick up the level 1 backup during recovery. Instead he just used logs archived. I thought well, it will be used the newspapers archived on the level 1 backup if both were available.
In any case, I decided to test this. Yet once, I ran a level 0 backup. I then changed my recovery logs and then remove all logs archiving (obvisously recovery would be impossible at the moment). I then ran a level 1 backup I thought would recovery possible and switched it again connects again create logs to archive more.
Then, I removed some db files and tried to restore and recover the database. I expect to restore the database of the level 0 backup (which is), and then as I deleted logs archiving between the 0 and 1 level backup, I expect to use the level 1 backup and then use the remaining archivelogs after that.
However, RMAN has reported the following:
RMAN-06053: unable to perform the recovery of the media because of the missing journal
RMAN-06025: no log backup archived for thread 1 with sequence 335 and startin
g 7283154681366 SNA found to restore
What is going on?
Thank you very much
Adam
> I then removed some db files and tried to restore and recover the database
You use a recovery catalog schema which would be "in the loop" of all L1 backups, archivelog and L0? If you use a controlfile, you restore the backup of the controfile? What backup controlfile restore you? You need the controlfile is from a point after the backup of the L1 while it would be "in the loop" of the backup of the L1.

Before physical deployment standby with RMAN incremental backups.
This method is available in 10g:
http://Web.Stanford.edu/dept/ITSS/docs/Oracle/10gR2/server.102/b14239/scenarios.htm#CIHIAADC
For 11g:
http://docs.Oracle.com/CD/E11882_01/server.112/e41134/RMAN.htm#SBYDB00759
For 12 c:
http://docs.Oracle.com/database/121/BRADV/rcmadvre.htm#BRADV685
According to dosc 10 g, the scenario is simple:
1. create an incremental backup to SNA required on primary and copy it in standby mode
2 save the backup in sleep mode and perform a recovery
11 g dosc, we must recreate the standby control file and update the file names before performing the recovery.
12 c introduces the new method - recovery on network, but again, we must recreate and standby control file update.
The question is: why we must create new controlfile ensures g 11 and 12 c and can we use a simple method of 10g?
Thank you.
Hello
1 why the incremental backup application does not update standby controlfile?
-Your database pending is be retrieved using the incremental backup. This does not update the eve controlfile. Your standby controlfile completely ignores the last CNS to the primary database.
2. what happens if we leave the old standby controlfile? RFS will record new logs of the primary, but will ignore them MRP? If so, can update us standby controlfile by manually applying the following log?
-Your old standby controlfile is unaware of the last CNS to the primary database.
As Mseberg said, trying things on a test computer and you will have the answers to your questions.
Kind regards

STRATEGY OF RETENTION and incremental backups.
Consider the following scenario.
Sunday: level 0
Monday: level 1
Tuesday: level 1
Wednesday: level 1 cumulativeIf we make the recovery Friday, rman uses Level0, last level 1 and all logs after him. All other newspapers and incremental backups are not necessary.
Now assume that the retention policy is window of recovery of 1 or 2 days. RMAN will review these logs and backups as obsolete Friday?
Obsolete backups - backups are performed before the last full backup that is not obsolete. Because level 1 is not full backup, rman will retain all of the incremental backups and archive logs that are created after the 0 level.

So, I would like to confirm that I actually run differential backups and not be combined during the days of the week.
Anyone have a query which can check the type of backup that I used?
It s an OLTP database running Oracle 11.2.
Sorry for not adding the view all and everything but I m at home after working hours, try to understand this.
See you soon
Hello
User RMAN must use a name in the 'format' or 'tag' option or two to show
type of backup was made. For example:
database backup incremental level 0 format 'c:\temp\diff_incr_zero_%U.bak ';
or
database backup incremental level 0 tag diff_incr_zero;
Without the tag, or format clauses specifying the type of backup performed.
It is not possible to use the RMAN list or any point of view RMAN command to determine
the difference of these two types of backups.
Thank you

Unable to perform an incremental backup
I am trying to perform an incremental backup. I have an old full backup and I did another full backup yesterday. The last full backup was successful.
When I try to load the full backup for the gradual process, 13 items will just a State does not. I tried several times with two backups and her resut is always the same.
I don't see too many questions like that.
Solutions or causes?
Thank you
Weird. Tried to backup full and a differential still at night last with the largest catalog. Alll worked well this time.
