Yes , you should take a hot backup of catalog DB and also configure controlfile auto backup.

RMAN Backup using Rman Catalog

Hi
can we take backup of oracle9i database using oracle10g RMAN Catalog?
Thanks
With Regards
OH

I guess this is related to backward compatibility support principle. Target database's controlfile and RMAN catalog is synchronized and different version may have different structure and feature. When we need to completely restore an Oracle instance from backup, RMAN catalog must be able to support target database, and it may not be possible if RMAN catalog version is lower than target database. I hope I get the message across.
Pls anybody correct me if I am wrong

Unregister from rman catalog

Dear All,
Currently our production backup is done by rman with catalog database. But I want to decommission it. I want to use the target database controlfile only for rman backup.
what is the right approach to configure it?

Currently our production backup is done by rman with catalog database. But I want to decommission it. I want to use the target database controlfile only for rman backup.
what is the right approach to configure it?No ned to confiugre, while connecting to RMAN or in backupjob scripts just do not mention catalog connectivity.
If any old backups available then register them with controlfile..
in case of catalog :-
rman target sys/****@prod catalog rman/rman@catlog
in case of no-catalog:
rman target sys/****@prod
to register old backups:-
RMAN> catalog start with 'location of backups';

Doubt in taking backup using RMAN CATALOG

Hi,
when i was using RMAN CATALOG.
can i create separate database for catalog on server machin/backup server?
if create separate database for catalog?
how to create a separate database for catalog and plz give clear instruction one by one.
thanks

can i create separate database for catalog on server machin/backup server?
Yes.
and
also you create separate user to "recovery catalog" and "separate tablespace" for recovery catalog.
1.creation of recovery database catalog some like normal database catalog.
but after creation of database you create one user for recovery catalog.
Note :
"User that owns the recovery catalog schema. This is a user defined in the recovery catalog database that has been granted the RECOVERY_CATALOG_OWNER role."

Query RMAN catalog to view my controlfile backup in backup piece

version: 11.1.0.7
We need to restore an year old database and its backup is availble in TAPE, RMAN directly takes backup to TAPE.
we have dropped the database, Now there is a requirement to restore the database.
we Know DBID, I can restore the db once i can restore the contolfile.
However we did not have controlfile auto backup. whenever there is FULL/incremental backup cotnrolfile is included in that backup. now we have the rman catalog for that database. so How I can query rman catalog to find which backup piece containing the latest controlfile? once we know the backuppiece info, we can restore controlfile from that piece
any help on this?

set dbid <yourdbid>
list backup of controlfile;In this case you will see all backups of controlfile.And according time this backup you can restore database using

SQL Reports Bad Idea Against RMAN Catalog?

11.2.0.1 SPARC 64
We use OEM to manage/execute our backups. The MML is NetBackup. One downside to this is that the "job" within OEM executes the backup for 20+ databases. In a serial fashion the backups occur in NetBackup...but most are queued - they throttle through and over time they complete. To this end, we have no way of seeing the true backup duration. We know the rman start and completion times, but they're not "actual."
I started looking at creating a sql statement/report/[pl/sql] block that would give us the granular informatin on the true timings of the backup "pieces" as they relate to a "set."
Research out on the wire shows a number of high level solutions, but nothing to which a report shows the data files, etc. Usually when I see this I start to question..."hey, is this even a good approach?"
I do realize that through the RMAN utility there are a number of reports which are available...this post, however, is focused on the idea of sql reports against the rman catalog.
Any advice would be welcome.
Conceptual report:
-> INCREMENTAL LEVEL 0
--> BACKUP SET
---> BACKUP PIECE
----> HANDLE, TAG, DATAFILE, START, COMPLETION
I'm NOT looking for the sql...I can work that out, I just want to know if this is a smart approach or best to stay out of the catalog.

How to upgrade RMAN catalog from 10.2.0.4 to 11?

Hi, we are on Oracle 10.2.0.4, Solaris 5.10. Our RMAN catalog is 10.2.0.4 version and we have several 11g databases that need to connect to the catalog and obviously cannot. So we need to upgrade the catalog to 11. Does anyone have any docs on how to do it. Do I need to upgrade RMAN database to 11 via conventional upgrade and then do UPGRADE CATALOG? Really confusing, any help would be very appreciated.
Thank you!

You need to:
1 - upgrade the recovery catalog database
2 - upgrade the recovery catalog Schema
Please check the details on note *452529.1 Recovery catalog for RMAN backup*.
Normally newer databases (target) can be cataloged on previous version catalog database, but with 11g there is the bug 6756872 (RMAN REGISTER OF 11G TARGET INTO 10G CATALOG FAILS WITH ORA-04028) which force you to upgrade the catalog.
You can also review RMAN Compatibility Matrix (Note 73431.1) which has all valid version combinations.
If your scenario is simple enough, another option could be create a new 11g RMAN catalog and register there your databases, without importing data from the 10.2 catalog.
Regards.

Backup RMAN Incremental Level 1 without Level 0 - 10gR2

Hi,
I'm a bit confused after some tests.
The Question: It's mandatory to perform backup incremental level 0 before the level 1 using Oracle 10gR2 ?
On Oracle 11.2 it's mandatory but on Oracle 10.2.0.5 I don't know.
Test on 11.2. If doesn't exists level 0 rman take care about it and perform automaticaly level 0 before level1
RMAN> backup incremental level 1 database;

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
...Docs said:
Incremental backups capture only those blocks that change between backups in each datafile.
In a typical incremental backup strategy, a level 0 incremental backup is used as a starting point. A level 0 backup captures all blocks in the datafile.
So, on Oracle 10.2.0.5 this not happen like on 11.2:

Hi Gokhan,
Thank you for point this.
After spending a time studying about this I find out this:
Your expanation apply only in Oracle 10gR1/R2.
Because there is differences between RMAN Version 10gR1/R2 and 11gR1/R2 about Incremental Level 1 and this confuse me.
Oracle 10gR1/R2 run only one backup incremental level 1 even if level 0 not exists .
Oracle 11gR1/R2 run two backups incremental if level 0 not exists. i.e level 0 first and after that level 1.
Oracle 10gR2
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.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm
Thats means wich RMAN run level 0 with name level 1. (i.e: Only one Backup) This is confuse.
Oracle 11gR1
If no level 0 backup is available in either the current or parent incarnation, then the behavior varies with the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks that have been changed since the file was created. Otherwise, RMAN behaves as it did in previous releases, by generating a level 0 backup.
http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmcncpt.htm#BRADV89500
Oracle 11gR2
If no level 0 backup is available in either the current or parent incarnation, then the behavior varies with the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks that have been changed since the file was created. Otherwise, RMAN generates a level 0 backup.
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmcncpt.htm#BRADV89500
Thats means wich RMAN run (automatically) level 0 first after finish level 0 backup RMAN run level 1 backup (i.e Two Backups). This seems right.

Question: Which is better and why....RMAN catalog or Flashback Recovery

Hey All,
Newly testing and reading up on 10g. I am on information overload and would appreciate pro's advice on which to choose and why.
Thanks,
d.

Different things, not necessarily alternative. That is, RMAN catalog is normally (at least should be) on another machine, and does not contain physical backups, but only information about them : physical backups are normally stored on external devices, like tapes.
Flashback Recovery technique is based on Flashback logs in Flash Recovery Area, which is a disk area on local machine, and so cannot be unlimited.
Therefore, Flashback Recovery is much faster than Media Recovery, since you don't need to restore anything, but you have limits in using that : your disks size.
On the other hand, RMAN backups are safer, being physically elsewhere.
See http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/backrec.htm#g1023042

To Find the instance name in RMAN catalog

Hi ,
I have rman catalog which got registered 150 databases. Am able to get the dbname,id for the 150 databases but not able to get the server name (host name) of the correspoding databases in catalog views as well as in db views.
Kindly revert us if you know any other analyisis or way to find the server names.

What does RMAN care if RAC is involved or not?
Oracle provides RMAN for backing up and restoring the database. RMAN enables you to back up, copy, restore, and recover datafiles, control files, SPFILEs, and archived redo logs. RMAN is included with the Oracle server and it is installed by default. You can run RMAN from the command line or you can use it from the Backup Manager in Oracle Enterprise Manager. The procedures for using RMAN in RAC environments do not differ substantially from those for Oracle single-instance environments. Refer to the Oracle Backup and Recovery documentation set for more information about single-instance RMAN backup procedures.

Why use RMAN CATALOG ?

Hi,
Anybody tell me why use RMAN CATALOG and what benifits if i have create catalog ?

No we have to configure it. I see. But did this user understand that when you quoted my reply ? We need to understand that a lot of users who post here need help and may not have the level of knowlege you have. So, a response like that adds more problems to the one they already have.
So even if you are using nocatalog, if it is not configured to auto backup and it is not backed up, you can still loose your RMAN repository.

Unregistering of a database from RMAN Catalog

Hello,
We had set up RMAN backup though RMAN Catalog for one of our database.
We later decided not to take the backups of this particular database. One of the DBA did something but what we can see now is that -
1. Target database is not registered in the catalog so no information can be gathered rman prompt after connecting to catalog through target database
2. But the recovery catalog "rc_backup_datafile" is showing as if it has old backups
We know that the tapes don't have the backup of this database.
Question - How to remove information from recovery catalog for a database in such a situation where although the database is not registered in the catalog but somehow the information related to old backups still persists in the catalog tables.
Thanks!

Thanks Tycho, for my purpose DBMS_RCVCAT.UNREGISTERDATABASE worked fine.
I have another question though -
We have compressed backup for one of the database/
If I look at backupset by executing "list backupset xxxxxxx;" command it shows the correct compressed value (in GB) of the backup set.
BUT when I look at the rc_backup_datafile table of the rman catalog for the size of of the backupset, it shows the uncompresses size of the backupset. I am using following query -
select BS_KEY,SUM(blocks*block_size)/1024/1024/1024 GB from rc_backup_datafile where DB_NAME='CCSTG04' and BS_KEY=1 group by BS_KEY;
Question - How to check the compressed size of the backupset from the Catalog tables/views?
Thanks for your help on this!
Thanks!

How to get RMAN catalog information from Target database?

Hi,
How to get RMAN catalog information from Target database because i don't know about catalog database? is it possible?
Thanks

If you run RMAN backups of a target database using a Catalog schema in another database, the target is not aware of the catalog.
The RMAN backup script would have the connection identifier for the Catalog.

RMAN catalog fails to show target database information when in nomount mode

Hello everyone, I am trying to restore a dev. database from its own backup taken a week back. The DB is in noarchivelog mode and recently 2 of the datafiles were removed from the files system and thus the need to restore the DB from its backup. However rest of the files and control files are intact.
Now, when I put the database in mount mode and connect to the catalog then I can see the DB's incarnation;

Hi,
You won't be able to see incarnation information when the DB is in "nomount" since the incarnation is written in the control file. I don't think the catalog has this information.
Anyway, in order to restore datafiles, the instance must be mounted, so you should be OK.
Mount the instance and just restore the datafiles.
