RMAN LEVEL BACKUP INCREMENTAL 0 AND 1 OF CUMULATIVE LEVEL
Dear friends
This is Eliza, I need some clarification, your suggestion will help me more...
Currently I am working in RMAN backup and restore, recovery and I need to take the extra SIZE 0 AND LEVEL 1 CUMULATIVE
I know something about what level rman incremental 0 and level 1 cumulative can do is, first I have to take the level 0 and then level 1 respectively.
As follows
SUNDAY: LEVEL 0 CUMULATIVE
MONDAY - SATURDAY: LEVEL 1 CUMULATIVE
SUNDAY: LEVEL 0 CUMULATIVE (repetition of this cycle)
MY QUESTION IS
Can I use after an order to take INCREMENTIELLE LEVEL 1 CUMULATIVE backup of,
CUMULATIVE DATABASE INCREMENTAL LEVEL 1; # has changed since the level 0 blocks
But, if I want to take CUMULATIVE INCREMENTAL level 0 BACKUP, that is me I want to use the following,
INCREMENTAL LEVEL 0 BACKUP CUMULATIVE BASIS;
(GOLD)
DATABASE INCREMENTAL LEVEL 0 BACKUP;
(GOLD)
Suggest me your valuable idea. Thanks in advance.
Hello
I think that this CUMULATIVE or incremental level 0 backup specification makes no sense so INCREMENTAL level 0 BACKUP database; = INCREMENTAL CUMULATIVE 0 DATA LEVEL;

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.
Concerning
MeHello
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

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
0and1are 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.

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
Docs said:RMAN> backup incremental level 1 database; Starting backup at 29-APR-11 using channel ORA_DISK_1 no parent backup or copy of datafile 1 found ... channel ORA_DISK_1: starting incremental level 0 datafile backup set channel ORA_DISK_1: specifying datafile(s) in backup set ...
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:

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="">

Problem with the archive log when you use RMAN for backup and restore (11g 2)
Hello world
Please help me solve this problem.
I'm just beginner in Oracle Database (11 g 2). Today, I had a problem, I tried to back up and restore my db by RMAN. I delete all the files in /u01/app/oracle/oradata/orcl / * , then I restore them easily, but the point is I have a table, I can restore Hungarian, but cannot restore anything ranks in it (something wrong with step restore database). I'll tell the detail below.
-First, I create a 'Day' with command table create table hr.day (varchar (20)) day. Then I backup complete by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_FULL_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 0 tag 'DB_FULL' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_FULL' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}
D ' other hand, I have insert 'Monday' to table. then do an incremental backup by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_INC_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 1 tag 'DB_INC' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_INC' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}Repeat 7 times (Monday-> Saturday). And I got these files:
[oracle@rac ~]$ ls -l /u01/backup/

If i ignore it and open the database, just my table in full backup come back but rows was not restored. I'm sure the problem is my archive log backup but i don't know how to solve it. Plz help me.Sorry for a long post.> 1 and from the 1205841 SNA sequence
The SCN that indicates Oracle is above the range of SNA that you have in the ArchiveLog backups for sequence 1 to 15 (15 sequence ends at 1205840).
The message
channel ORA_DISK_1: restoring archives Journal
Archives journal thread = 1 sequence = 15
channel ORA_DISK_1: backup/u01/backup/DB_INC_ORCL_20160120_s117_p1 piece reading
channel ORA_DISK_1: piece handle = / u01/backup/DB_INC_ORCL_20160120_s117_p1 tag = ARCL_BKP_INC
indicates that he has restored the sequence up to 15
You can check the log file alert database instance for messages on the fact of recovery.
He is now asking sequence #1 it seems you did a RESETLOGS after sequence #15.
Note: If you have NOT issued a COMMIT after the line is INSERTED in the table 'Day', the recovery of the database will have no * transactions * to retrieve. An uncomitted transaction is cancelled.

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)

When the RMAN brand is backup incremental level1 obsolete?
Hi all
On a server Oracle 10.2.0.2 particular (with ODG), I implemented a strategy of incremental backup. A level 0 backup is available and all level 1 next backups are getting recovered to this first copy of data file. So far so good.
The problem is that all these incremental backups at level 1 stay in my box of flashback and are not cleaned by RMAN. The retention policy is set on a window of 1 day.
When the RMAN will start scoring these backups to level 1 as being obsolete? I guess that these backups are obsolete right after that they were applied to the copy of the data file? This has something to do with the size of the parameter area flashback, which means that it will not begin to remove level 1 backups when RMAN runs into problems of free space on the disk?
Any help is appreciated!
JMHi JM,
This is expected behavior, because you have changed the default retention of redundancy strategy 1.
You can find this on My Oracle Support note + incremental backup strategies: Merge [ID 745798.1] +.The extract of this says:
>
When using Oracle-Suggested policy or a daily incremental backup merged and using a Flash recovery area and then keep the retention policy of RMAN for redundancy 1. This will ensure that the Oracle space management will automatically remove incremental backups at level 1 of the FRA after they have been applied to the image based on the pressure of space in the FRA copy. If you increase the redundancy or set a window of recovery space is is automatically retrieved by Oracle. This works only when the retention policy is set to the default value of redundancy = 1. If the configured retention policy is set to the window of recovery or > 1 redundancy, RMAN cannot satisfy the retention policy if there is only one copy of database and it's at a later point in time. Thus, in order to satisfy political retention Oracle keeps all the incremental backups and archivelogs since the creation of the database because ideally a data file can be re-created and archivelogs can be applied to meet the retention policy (although not followed in the practical case).
>To have made them obsolete automatically, you must add the 'UNTIL TIME 'SYSDATE-2' ' clause to the COPY of RECOVER sentence, for a 1-day recovery window.
The order having to RETRIEVE it after the BACKUP, you will have the current copy image, and you should only apply the archivelogs if you need to recover instead of use the last day of Level0 backup now level1.
Kind regards.

RMAN backup to tape and disk script
Hi all,
I'm looking for a script to backup on tape and disk using an RMAN command. There is that one parameter, I don't want to understand, I've seen evidence of. Backup of the Flash recovery area. I want to be able to do it from the location of the files. I want to back up the database complete, kitchen sink and everything.
Can anyone help?
General information.
Database 10 g 2, Grid Control 10.2.0.4, Linux RHEL4.6 Server. If you need more information please ask me.
Thank you all!This can be by setting up your backup channels,

backup incremental update feature
Hi all
can you explain this feafure when you take the copy of the image and then backup incremental and when
data file is corrupted I have to restore the copy of the data file, and then apply an incremental backup.
I do this planning, but I do not write the COPY OF THE file of DATA WITH TAG RECOVER command
I take a copy of the image and then make this table spaces and make sure is the default value for the data base and ten make change
DML, stop immediately and drop datafile can restore and recover
restore the data file 5
recover datafile 5
without any incremental update command, feature and now my database is up-to-date? can you explain to me an example please?
Thank you very muchWe must use the control switch that will make the controlfile to point to the backup of the data on the disk files.
For example: you lost the data user 6 fileRMAN > switch datafile 6 to copy;
RMAN > recover datafile 6;
RMAN > alter database datafile 6 online;The problem with incremental updates, is that, after any failure, as above, if restore us it, it will change the name and location of the data file. After restoration manual you rename them to original location.
In case of failure of the database
RMAN > switch database to copy.
RMAN > restore database;
RMAN > alter database openPublished by: renee_mathieu on August 5, 2012 07:54

Export vs rman as backup strategy
I just joined new company and owner oracle DBA confessed that they have never used in all of their many years as a DBA Oracle rman. Currently, they have 7 days of files dmp to export for each prod database. I started to create backups rman for each prod dB and I asked if we can stop exports altogether. Holder s/n, says exports are still needed in case we need to restore a table or in the case where we need to refresh a development/test environment. I submit that rman can do and I communicated that I never used exports in a special or as needed case either to move an oracle dB between different operating systems or incompatible versions. All export their production databases every night? I've been an Oracle DBA since 10g but I've always been the unique oracle DBA in the shops/companies that I worked. It is the first time I had a DBA experienced to work with. I'm surprised actually kind of which my colleague has never used rman being that they are so widely experienced. Dig deeper, they say they have used the NetApp as their backup method and they try to get configured in my current company that tells me will make rman irrelevant. What do you think?

My, my, my. Your recent history of the display, you seem to have a lot of questions with your new business.
In this case, you are partially right. It is unacceptable for this "very experienced" s/n do not use rman and see no need of it. If his backup strategy should only take nightly exports, it has been lucky and lives on borrowed time. If the database is corrupted or lost, these exports don't you a good few until what you create - from scratch - a database of work. And even then, only, you will have a point in time as a recovery point.
NetApp is concerned, that I've never used but I understand that it is simply wraps around rman. Perhaps, this can be handy. Until the disaster where you also get trashed NetApp configurations. No, when it comes back up, and more important again, recovering from a disaster, I want to work closely with the oracle supplied and approved method. The extra layers less potentially go wrong, the better.
If they want to continue taking exports every night, he certainly won't do any harm, as long as they realize that is secondary to the required rman backups. All my databases are backed up with rman. Some but not all also have nightly exports. It depends on the requirements. There are some things for which having a practice of export is better than to rely solely on rman.

Oracle 12 c with RMAN database backup
Hi All-
I started back to the top of one of my PDB using utility RMAN following the instructions on the link below.
http://www.Oracle.com/WebFolder/technetwork/tutorials/OBE/DB/12C/R1/PDB/pdb_pitr/pdb_pitr.html

Back to the top has been done successfully, but when I started with the recovery process he gave me error reporting collection.

Thank you

Just a wild guess
You do not use this script in a command as Administrator window
Therefore, you won't be able to create any service.
I also have a question: your only troubleshooting activity consisted of hitting CTRL + C and CTRL-V, is not it?
It's so boring to most of the people here do not even TRY to solve their own problems.

RMAN-06820 / backup RMAN on a database of Eve / wallet using authentication
Hello
An attempt to resolution RMAN-06820 by putting together a portfolio for Doc-ID 1616074.1
RMAN-06820: WARNING: unable to archive the current log on the primary database-------------------------------------------------------------
Doc-ID 1616074.1 means Bug: 17580082
As for being able to connect standby to primary school, there are few options
(Option 1) is to connect as SYSDBA, as: 'rman target sys/password@stby.
(Option 2) is portfolio of configuration using the authentication that can be made (more information can be obtained by the SECURITY team).
(Option 3) using command CONNECT in the command file supplied to RMAN. For example: RMAN > Connect target sysdba_user/password@stby-------------------------------------------------------------
We are currently using option 1, but to remove the passwords from the scheduled RMAN script.
RMAN target sys/password@stby nocatalog journal @/ tmp/RMAN_SCRIPT = / tmp/RMAN_LOG
We look at option 2 implement a portfolio > ' use secure external password store (Doc ID 340559.1) '
We have successfully Setup a portfolio
$ mkdir $ORACLE_HOME/portfolio
$ mkstore - wrl $ORACLE_HOME/portfolio-create
$ mkstore - wrl $ORACLE_HOME/portfolio - createCredential stby sys passwordSQLNET.ora updated with
WALLET_LOCATION = (source = (Method = file) (METHOD_DATA =(Directory=$ORACLE_HOME/Wallet)))
SQLNET. WALLET_OVERRIDE = TRUEThe scheduled RMAN script is updated:
RMAN target /@stby nocatalog journal @/ tmp/RMAN_SCRIPT = / tmp/RMAN_LOG
I always get RMAN-06820 WARNING.
-Anyone have a solution to resolve the WARNING of RMAN - 06820 for an RMAN backup on a database ensure using a portfolio (Doc ID 1616074.1 Option 2) for authentication?
Kind regardsRichie.
An update for you to know that this isn't a problem.
I have re-implemented solution (recreated portfolio / updated the rman script to remove password) and his works now.
I'll go through this myself to see what I missed the first time.
Therefore, please note that Doc ID 1616074.1 Option 2 (workaround) put in place a portfolio (Ref: Doc ID 340559.1) is 100% successful.
set up a portfolio:
$ mkdir $ORACLE_HOME/portfolio
$ mkstore - wrl $ORACLE_HOME/portfolio-create
$ mkstore - wrl $ORACLE_HOME/portfolio - createCredential stby sys passwordSQLNET.ora:
WALLET_LOCATION = (source = (Method = file) (METHOD_DATA =(Directory=$ORACLE_HOME/Wallet)))

RMAN bypass backup can be taken from question?
Hi all
pretty simple question (I hope that ):
I use the suite at the moment for example:
run
{
Backup CONFIGURATION DEVICE TYPE DISK PARALLELISM 2 to compressed backupset;
TIME 01:00 PARTIAL minimize THE time data BACKUP FILESPERSET 1;
}But I was wondering if there is some way to this running as a backup script planned to restart backup, if it does not (due to problems of space file etc.)
run
{Configure the disk channel CH1 device type format ' / alternate/path/for_backup/%d_DB_%M%D%Y_%p_%s_%U';
Configure the disk channel CH2 device type format ' / alternate/path/for_backup/%d_DB_%M%D%Y_%p_%s_%U';
TIME 01:00 PARTIAL minimize THE time of BACKUP data NOT BACKED UP SINCE TIME ' SYSDATE - 1' fileperset 1; < < < I know it won't work like that but y at - it another way to accomplish this? (work around to restart the backup time and the option to reduce time?)cleaning etc release channels
}
PS: question side bonus points
who can tell me more about the loss of speed MB/S compared to the rate of compression: low/medium/high?
I hope that there are some brilliant minds out there willing to help!
Thanks in advance.
The themes you mention seem to be covered in the Advanced documentation of RMAN:
http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmbckad.htm#BRADV89540
I don't know if anyone can really give you an opinion about which compression will have the best size vs time full report. But the next test by using a simple vanilla ORCL database shows the result of the compression of 'low '. It was done on sub Oracle 11 GR 2 one running a VirtualBox VM. As you can see there is a reduction of the large size of the backupset, which however has taken so long to complete as to the 'no' compression.
RMAN> CONFIGURE COMPRESSION ALGORITHM clear; RMAN> backup database; RMAN> list backup; BS Key Type LV Size Device Type Elapsed Time Completion Time ------- ---- -- ---------- ----------- ------------ --------------- 40 Full 1.20G DISK 00:00:08 22-JUN-15 BP Key: 40 Status: AVAILABLE Compressed: NO Tag: TAG20150622T123329 RMAN> CONFIGURE COMPRESSION ALGORITHM 'LOW'; RMAN> backup as compressed backupset database; RMAN> list backup; BS Key Type LV Size Device Type Elapsed Time Completion Time ------- ---- -- ---------- ----------- ------------ --------------- 44 Full 400.38M DISK 00:00:08 22-JUN-15 BP Key: 44 Status: AVAILABLE Compressed: YES Tag: TAG20150622T123811Why did you write that I know that it won't work like that? According to the example below, I don't see the problem. As you can see on the 2nd run of the backup command, it ignores the data files that he has previously treated.

Backup Tables, triggers and packages/procedures
Oracle 11.2 and Developer SQL 3.2.
For the backup of the data, I use OEM/Rman to schedule a backup. My understanding, these are usually data only (physical backup).
Now, I want to make the backup of the logic for the tables, packages/procedures and triggers. I currently use Oracle SQL Developer to export as separate SQL files.
I wonder if there are any other options to save the tables, procedures and triggers?
Currently I am guard three types of backups:
(1) creation of user scripts, role and grant the user privileges.
(2) tables, packages/procedures and triggers saved via Oracle SQL Developer
(3) data ora saved through OEM
Total crash of DB, I'll run the script to create users, role, and grant privileges. Then log in as an authorized user and run the sql scripts to create the tables, procedures, packages, and triggers; Finally, to recover the data via RMAN.
Is this a good practice for backup/recovery, or there are ways to do better?
Thank you.

Additional OEM backup.
The backup operation is made by rman.

RMAN backup of the physical database. Technically, it makes copies of data blocks in the data files. He does not know, nor she cares, that contains a given block. And this data block "term" is wider than you can imagine. Consider this: the entire database - tables, indexes, the data dictionary (which itself is nothing more than a collection of tables), stored the DDL, code compiled... everything fits in these data files and data files are all made up of blocks of 'data '.
Now, I want to make the backup of the logic for the tables, packages/procedures and triggers. I currently use Oracle SQL Developer to export as separate SQL files.

That's what rman. backup of tables, procedures, triggers,... everything.
Currently I am guard three types of backups:
(1) creation of user scripts, role and grant the user privileges.
(2) tables, packages/procedures and triggers saved via Oracle SQL Developer
(3) data ora saved through OEM

DB crash, you want to have a database to run these scripts. You will FIRST need to restore/recovery database... backups rman.
Then log in as an authorized user and run the sql scripts to create the tables, procedures, packages and triggers.
; You don't have to run all the scripts, because all the tables, procedures/packckages, and triggers will have already been restored by rman when he corrected/restored the database.
Finally, retrieve the data via RMAN.
And, precisely, what do you think this means at this point?
Is this a good practice for backup/recovery, or there are ways to do better?
There are much better ways. Especially what you describe will not work.
You have a serious misunderstanding on what rman is and does. You need to spend some serious time, read the rman users guide, at https://docs.oracle.com/cd/E11882_01/backup.112/e10642/toc.htm
And, FWIW, I would NOT recommend depending on the OEM manufacturer to plan backups or perform a recovery.

RAC RAC CLONE OF RMAN cold backup
Hi all
I need your help in my Oracle RAC 11.2.0.2 to remote host environment cloning. Here's the disc structure
DGVOT (disc ASM holding OCR and voting disk group)
DGDATA (disk group ASM containing data files)
DGFRA (disk group ASM files for fast recovery)
Remote host is on a different location so cannot use duplicate RMAN with auxiliary channel.
Have the luxury of downtime so I wanted to take coherent RMAN (Cold Backup)
SAME structure of the disc is available on remote hosts.
11.2.0.2 CLusterware (IG) over the oracle binaries are already installed.
Can any body tell me the steps to
(1) how to take cold backup on the disk so that I can tar and copy to the remote host
(2) clone of the database on the remote host
(3) how do I add the listener for the database and other resources of this databasee clusterware.
in fact, it's my first clone CARS, so I'm well aware of the steps in detail.
I went though a lot of notes metalink but nobody fits my needs. your tips will help me a lot
Kind regardsHello
(1) how to take cold backup on disk so that I can tar and copy to the remote host.
Use Rman cold backup
At the stage of the mountain run
RMAN > backup database archivelog format '%U /dbp ";
RMAN > backup controlfile current format "%U /ctl"; Copy these to the remote host backup sets
(2) clone of the database on the remote host
Create groups of similar ASM disk as source
create pfile/spifile, starting in nomount mode instance
backup set from catalogRMAN > catalogue start with "
"; Restore controlfile
RMAN > restore controlfile;
RMAN > restore database;
RMAN > restore database;
On the success of the recovery
RMAN > sql 'alter database open;
(3) how do I add the listener for the database and other resources of this databasee clusterware.
Srvctl user to add resources
Use: srvctl
