Block Media Recovery and RMAN backup incremental level 1

Hello

I read somewhere that block Media Recovery will not work if a database is backed up with 1 incremental rman. Is this true and if so is there a work around?
I can't find it in the documentation of oralce.

Hello

Yes you are right, for the recovery block media, you must have full rman backup. Incremental backups are not used by block
media recovery. Only full backups and archived logs are used.

See this doc on part III

RMAN backup incremental level 1 without level 0-10 gr 2

Hello

I'm a bit confused after a few tries.

The issue: It is mandatory to perform incremental level 0 backup before level 1 using Oracle 10 g 2?

On Oracle 11.2 is mandatory, but I don't know about Oracle 10.2.0.5.

11.2 test. If there is no level 0 rman take care on this subject and automatically perform level 0 before level1

RMAN> backup incremental level 1 database;

Docs said:
Incremental backups capture only blocks that change between backups in each data file.
In a typical incremental backup strategy, an incremental backup of level 0 is used as a starting point. A level 0 backup captures all the blocks in the data file.

So, on Oracle 10.2.0.5 happens not like 11.2:

Parade level 1 without level 0 backup:

Levi,

Please visit: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm

If no level 0 backup is available, then the behavior depends on the setting of compatibility mode. If compatibility is > = 10.0.0, copies all blocks changed since the file was created RMAN and stores the results as a level 1 backup. In other words, the CPN at the time the incremental backup is taken is the creation of SCN file. 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="">

headers block (block media recovery with rman)
Hi Im following this tutorial (sound on media with rman block recovery) - im using 11 GR 2 on oel 5.5

http://kamranagayev.WordPress.com/2010/03/18/RMAN-video-tutorial-series-performing-block-media-recovery-with-RMAN/

I created 2 spaces and storage within an array, for example I have a table space called "users02", composed of a data file called "users02.dbf", which currently holds a table called "tbl_test01".

If I query the table to select * from him, he returns the data inside, but when I use the following statement to determine the block header (for the purpose of the tutorial) no row is returned...
```
select header_block from dba_segments where segmemt_name='tbl_test01';
```
can someone help me on hwo I can find the header of the table,... is block - it possible that segment name is different in the name of the table?

Any help would be appreciated

Backup incremental level 2,3,4 RMAN.

Hello guys,.
Can someone let me know what is the meaning / usage of incremental backup of level 2,3,4.
Kind regards.

Wikipedia can have an easy to understand the reason for several additional levels:

A backup of level 1 decision Monday would only include changes made since Sunday. A backup of level 2 decision Tuesday would only include changes made since Monday. A backup of level 3 Wednesday would only include changes made since Tuesday. If a level 2 backup taken Thursday, it would include all changes made since Monday because Monday was the most recent level n - 1 backup.

What is RMAN?

The Oracle documentation refers only to additional 0 year 1. What I understand, RMAN never supported incremental backups multilevel at 3 levels (0-4). Apparently, people often had trouble understanding the logic for levels 3 and 4. RMAN provides the clause 'cascading', which also existed in 9i and is usually an easier to understand the backup strategy. RMAN also provides or has provided an option to perform incremental backups cumulative at level 1 or higher. For simplicity, the la documentation documentation since 10 g mentions only level 0 only a 1 an other levels is deprecated.

BACKUP INCREMENTIELLE from LEVEL 1 (differential by default, changes made since the last level 0 or 1)

BACKUP INCREMENTIELLE LEVEL 1 CUMULATIVE (changes since the last last level 0)

Below some info from http://docs.oracle.com/cd/E11882_01/backup.112/e10643/obs_comm.htm#RCMRF910

RMAN version 10.0.1: levels other than 0 and 1 are deprecated.

If you make an additional workforce 1 backup, incremental or cumulative, and there is no previous level 0, RMAN automatically performs an incremental backup of level 0. BTW, a full backup is identical to a level 0 incremental backup but excluded a strategy of backup incremental level.

Why the format does not work on my backup incremental level 1 the difference?

I use following script to make a backup of difference incremental level 1.
------------------------------
Run {}
allocate channels ch1 disc type;
Set order id "Monday_INC_1_df";
backup as compressed backupset database incremental level 1
format ' / opt/oracle/rman/bk/incr1_df_%d_%U'
tag "Monday_INC_1_df".
database more entered archivelog delete;
output channel ch1.
}
-------------------------------
According to this scenario, all the rman output files are placed in "/ opt/oracle/rman/bk / '... And his label is 'Monday_INC_1_df'.
But at the bottom of the newspaper, I find the archived log rman output files located in "/ opt/oracle/flash_recovery_area/TEST/backupset/2014_12_02 / '. And his label is "TAG20141202T210529".
Also, at the bottom of the newspaper, the output data files rman files was partly on the right path "/ opt/oracle/rman/bk / '. And it seems that the data files has been supported for 2 times. The second time datafile rman output files was badly located in the path "/ opt/oracle/flash_recovery_area/TEST/backupset/2014_12_02 / '. And his label is "TAG20141202T215627".

You have specified the keyword 'database' twice in the backup command. If execution is in the specified format, the second with the default format (to the FRA)

Implications of losing the directory ArchivedLogs and RMAN backup.
DB version: 10 gr 2
We have a database of test that is important, since this is a pre-production DB used by the application for the final test team.

Currently this DB is not in Archivelog mode. Every night a cron job runs to create the dump of datapump expdp of patterns in this PB.

We want to test the RMAN backups online in this PB. So, let's put this db in ARCHIVELOG mode for a week.

The RMAN backup items will be stored in c++ / u03/data1/orabkp + and archived logs will be stored in c++ / u04 / directory ach_logs +.

We want to know the impact of/u04/ach_logs, the directory of archived newspapers getting accidentally deleted. I know that the accidental removal of the RMAN backup directory should not affect the normal operation of the database. But we want to know if the accidental deletion of archive redo logs directory will affect the DB.

Published by: user10633418 on 25 Sep, 2009 02:53
NO, it will not affect the database. If you delete the files of the database archive logs will work normally. But you restore your database to the point in time. For recovery, you need your full backup of all data files + archivelogs online redo log files.

For a policy of backup of a production database where you won't lose any transaction that you must book your archive saves files of rman backup.

VMware CBT (tracking changes block): ctk files and multiple backup systems?

Hello
We have 2 datarecovery running backups of the SAME virtual machines, but on the other day.
Later, we will have a dedicated backup solution, so we will use only 1 VDR + external backup system.
The external backup system use CBT too.
Now my question is: how CBT done when several backup systems require "that is the last blocks changed since the last backup?
I mean if I run Sunday, on the same VDR2, VMs and VDR1 Saturday to VDR2 always have only the changed blocks from Saturday to Sunday and the blocks changed the week lack? !!!
Could someone provide me a technique explaining the depth of the CBT mechanism?
Thank you

Yes, once a block is modified the corresponding location in the mapping file is labeled with the new changeID.

Yesterday, we detected this error because SQL do not run.

The error repeat 47times and there are 6 different files-block combination (4 index of schemas, tables sys and ¡2 1!)

First of all, I launched expdp and exp of a problematic figure. Exports were fine, no error when you export, but in the alert.log don't show a block corruption. He exp and experienced display error and stop?

Then, I used dbv and check all dbfs. Display only the 2 error of blocks in two data files (index).

Then, I have used RMAN:
(A) database check: no error.
(B) validate the database: error in two blocks (logical error) and different from the 6 in the alert.log. The two blocks are clues.

I re - create the two index. When I re - create, the block error disappear (not immediate, assume that disappear when the block was rewriting). Now, dbv and rman show no errors.

I read a note on the types of errors, the other on procedures if db is in archivelog/noarchivelog. Also if the object is a table or index. But I find nothing corrupt self-repair blocks in Oracle or why now the 6 block error are resolved. I don't know if the two tables with two block corrupt lines lost or not.

Appreciate any help.

RMAN backup on a RAC env

We have a 2 camera database Oracle Enterprise Linux version 11204 node.
Please can you advice as to why my RMAN backup, ongoing assessment of the default value, so as ive defined the location of backup as below?
RMAN > show channel;
RMAN settings for database with db_unique_name GEOHUBPR are:
CONFIGURE CHANNEL DEVICE TYPE DISK CONNECT 1 ' *';
CONFIGURE THE CHANNEL 2 DEVICE TYPE DISK CONNECT ' *';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT ' / mnt/san/odanfs/rman_backup/%D_%U.bak';
run
{
SAVE as COMPRESSED BACKUPSET TAG 'geohubpr_L0_db' SIZE EXTRA 0 DATABASE;
BACKUP to COMPRESSED BACKUPSET TAG 'geohubpr_L0_arc' ARCHIVELOG ALL NOT SAVED;
}
Kind regards

There is a syntax error, you must add the word "database":

RMAN > backup incremental level 1 CUMULATIVE as Tablet backupset TAG 'geohubpr_L1_db' format ' / mnt/san/odanfs/rman_backup/%D_%U.bak' DATABASE;

Also include the archives in your backup

Block the recovery logs and flashback media (11g)
Are flashback logs required to block media recovery? Or are they just a nice-to-have?

According to the documentation online,

http://download.Oracle.com/docs/CD/E11882_01/backup.112/e10642/rcmblock.htm#BRADV89785

•Flashback database must be enabled on the target for RMAN search database logs the flashback of good copies of the corrupt blocks. If flashback logging is enabled and contains no corrupted corrupt blocks older versions, RMAN can use these blocks, possibly to speed recovery.

But, for me, is not clearly say that block media recovery cannot be performed without flashback logs.
The documentation is certainly confusion, but flashback logs are not required to block media recovery. With 11g, flashback database is enabled, then Oracle can actually use the flashback logs to potentially speed recovery.

How to restore the Rman incremental level 0 backup if the SID is different?
Hi Experts,
I had a little problem with restore rman backup of level 0. I have backup rman for oracle 11.2.0.1.0 - 64 bit and restore the server to Test 11.2.0.1.0 - 64 bit.

Problem:
Sid = prd production server
Sid = prderp test server

Operating system is Oracle linux 5 on both servers.

How to restore Rman if the SID is different?
Hello

Refer to this http://shivanandarao.wordpress.com/2012/04/19/duplicating-primary-database-to-a-new-host-without-connecting-to-the-primary-database-in-oracle-10g11g/

You need to restore it under the same name as you have in the production and later change the dbname using the NEST.

If you don't want to go with this method, then I suggest you to go with the method of double RMAN.

RMAN backup and restore into Production KEEPS RAC and DATA
Hi gurus of the Oracle

We need the expert advice for tune and cross check the RMAN Script for Production environment below below

Please suggest any corrections or comments on below mention scripts which will be executed on RAC and Production DATA GUARD environment

LINUX RHEL 5.5 64-bit
ORACLE GRID Infrastructure R2 Version 11.2.0.3.0 (we use ASM Cluster File system)
ORACLE11g R2 Version 11.2.0.3.0

We planned for basically rman backup drive using control file target instead of recovery catalog database

We will have Data Guard Setup between 2 remote sites of database and two remote sites have running the local 2-node RAC database

Thank you mseberg

This command is the full backup or a backup of level 0?

full backup as compressed backupset
data include current controlfile more archivelog deletion entry;

We use command below for the full backup of database.
database backup incremental level 0 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL0_%D_%M_%Y'
include current controlfile
tag 'datafile_full ';

We use the command below to the increment backup
database backup incremental level 1 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL1_%D_%M_%Y'
include current controlfile
tag 'datafile_Incr ';

What is the different when we use
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

or

full backup as backupset compressed database include controlfile current more archivelog delete all input;

tape backup fail with RMAN-03002 RMAN-20201 and RMAN-06010
Hello

My level 0 backup failed over the weekend and I don't understand why. I know I have four data corruption with files, so I put the MAXCORRUPT to 5 for these specific files so the continuous backup to work. This script has completed successfully in the past, and the structure of the database has not changed since the last backup of level 0 has been taken using this script. Here's what I see in my log file that displays the RMAN script, I used to run the backup and the following error messages:

Design question about backups and RMAN
I am pretty green with RMAN and need happen to a backup process that fits within my environment who are:

(1) disc can hold the PLUS 1 full backup and the value of the day of archive logs
(2) tape can hold up to 30 days of archive logs and backup complete for the whole duration so
(3) our tape backup solution don't play nice with RMAN so the method we use is THAT RMAN writes to disk and our copies of backup tape from a location on the tape drive.

What I want to do is trick recovery catalog thinking 30 days ago or more games of backup to disk, while having only a day on the drive actually. Is this a smart move, or can I keep the catalog of recovery in harmony with what is on the disk (so keep backups on disk only in the catalog) and if I need to come back in 2 days or more in the past, re-Catalog backup sets restored a strip (if that is even possible)?

Thank you

I also have a similar setup at my end taking the RMAN backups on drives and back up tapes. But in my case, I supported the RETENTION POLICY to REDUNDANCY 2. So full backup which is more than 2 copies is removed.

In your case, as you said, you have 2 options:
1. simply delete the backups on disks (as they were already saved to tapes) and a full backup. Here, you will not run an OVERLAP as well as no. invalidate the old backups in the catalogue, or recovery

2. maintain RESTRAINT POLICY to REDUNDANCY 1, whereby your recovery catalog has accurate status on the backup information. In this case, you must keep the AUTOMATIC backup with your full backups in the bands. If you lose you will have troubles recoveing the backup of this day.

In my opinion the 2nd option is preferable, although you have to recataloguer to use it. I tested how recovery with this situation on my blog at: http://oracleendeavor.blogspot.com/2010/02/disaster-recovery-using-rman-backups.html
