Regarding Rman

hi all,
Please tell me the difference between the below two commands,
1)backup database plus archivelog delete input;
2)backup database plus archivelog all delete input;
and what does this "delete input" will do,
please help me out in this.
Regards,
Vamsi.

Hi Vamsi;
To back up archived logs, datafile copies, or backup sets, then delete the input files from the operating system after the successful completion of the backup. RMAN also deletes and updates repository records for the deleted input files.
If you specify DELETE INPUT (without ALL), then RMAN deletes only the copy that it backs up. If you specify ALL, then RMAN deletes all copies of the specified logs that it finds in the V$ARCHIVED_LOG view.

Regarding RMAN backup and recovery using archivelogs during cloning process

Hi there,
We are running 9i database (RAC) in archivelog mode.We are in the process of cloning DEVELOPMENT database using our PRODUCTION database.
For this we planned to take RMAN backup by keeping the production database in MOUNT stage.
In this regard, will it be possible to make use of archivelogs generated during and after this backup (in mount stage), after some days during recovery time, if it asks for recovery after cloning process.
Thanks,
Balu.

Hi Alok,
why there is a need for standby here? you mean to say standby db?
what i exactly need is , whether i will be making use of archivelogs which are all archived during that backup period (in mount stage) after some days, if i face any problem with the PRODUCTION Database..

Query regarding RMAN

Hi Gurus,
my rman backup has failed, i have not issued any log file for rman. Does the rman creates any alert log file. If yes, where it is created whether in target database or catalog.
Thanks

hi,
how do you know it failed? I don't believe that a log file is written unless you ask for one.

Clarification regarding RMAN usage

Hi refering to http://www.dba-oracle.com/real_application_clusters_rac_grid/recovery_catalog.html
i have two DBs one CATDB(on oracle 9i) and other PRODdb(on 10g)
now i have created recovery catalog in CATDB .
My doubt is while registering the database. from which machine shall i run rman (machine having 10g or 9i or can i invoke RMAn from either of them).
rman TARGET sys/oracle@PRODdb CATALOG rman/cat@catdb
in the above given step i have doubt. which RMAN to use? 9i or 10g or it does not matter.
Thanks

Regarding rman user session

hi all,
i need to create a trigger for tracing a particular user session or rman session so that only one trace file is used throughout, regardless of there number of logins or logoff
thanks

Create a logon trigger, that checks for a certain login-name
We do the same for checking applications that log on.
Remember that if you're calling a procedure from the logon trigger, you have to disable the trigger every time you work/develop on the procedure.
Otherwise the trigger gets Invalid and all logons are denied
I can't show you the code we use now, because our storage-network has failed
Edit: Back online
The code
CREATE OR REPLACE TRIGGER check_logon_logging
after logon on database

How to read RMAN data into an ORACLE Table?

Hallo,
With regards to RMAN, how should we store the data into a database table, from the commands which can run only on RMAN prompt without using Recovery Catalog?
For Example:
RMAN> Report need backup days 3;
RMAN DATA:
RMAN-03022: compiling command: report
Report of files whose recovery needs more than 3 days of archived logs
File Days Name
1 1203 D:\ORACLE\ORADATA\TEST\SYSTEM01.DBF
2 1203 D:\ORACLE\ORADATA\TEST\RBS01.DBF
3 1203 D:\ORACLE\ORADATA\TEST\USERS01.DBF
Should it done via UTL_FILE?
If so, could someone give simple example/code how to do that, in order to write this RMAN data into an Oracle Database table?
I also set the utl_file_dir parameter to a particular directory in my database.
Thanks
W.Benvort

Actually, I am not using Recovery Catalog, so the views like RC_database, Rc_tablespaces etc , which are specific to recovery catalog are not available.
r.- this make sense at 100% because those views belong to the recovery catalog.
So, I wanted that these information, which we can get via using the commands like above, transfer into an Oracle table
r.- If you want to access the views of the Recovery Catalog to store part of that information in tables you have to have the database registered in a Recovery Catalog.
Should we keep the Recovery Catalog in Control file? Instead of using separate Schema.
r.- I recommend you to create a catalog for your database because the space the controlfile to store information regarding RMAN is reused and you can lose important information about your backups.
Can we run Catrman.sql script as a sys in order to keep the recovery catalog in sys schema?
r.- As you know, this is not recommended at all.
Conclusion : Create a Recovery Catalog and you will be able to perform all that you want regardind what you mentioned above.

Setting up RMAN -- Best Practice

On the readings I've done regarding RMAN, I've seen recommendations that RMAN should have a recovery catalog configured, even though that's optional. Further, I've seen recommendations that RMAN's recovery catalog should have its own database.
I've got one machine, that I want to run RMAN on, with the backups residing on that machine and disks. I then plan on archiving the backup files that RMAN produces to another set of cheaper, though less efficient, disks.
What I thought I'd do in configuring an RMAN recovery catalog is create a separate tablespace for it, and store the RMAN schema there instead of creating a separate database on the same machine.
It seems to me that unless you have an environment where you have one RMAN backing up multiple oracle instances, a separate RMAN database isn't justified.
Comments?

hi,
What I thought I'd do in configuring an RMAN recovery
catalog is create a separate tablespace for it, and
store the RMAN schema there instead of creating a
separate database on the same machine.
However if you just create a separate tablespace and you need to recover that database you will have major problems. If you are going to use the recovery catalog option then create a separate database ideally on a separate machine.
It seems to me that unless you have an environment
where you have one RMAN backing up multiple oracle
instances, a separate RMAN database isn't justified.if you have just a couple of databases to manage then use RMAN controlfile backup.

Resize online redolog files, make RMAN obsolute backups as usable

Dear Guru's,
I have following doubts, please clarify me on the same. thanks in advance
1. why can not we resize online redolog files instead of re-creating the same with large size and remove the older onces.
2. How can we make RMAN obsolute backups as usable ?

Regarding RMAN, plz look into below issue.
I configured RMAN backup recovery window of 15 days. after 15 days the backupsets which were older then 15 days are obsolute. now i have to restore the backup of 15 days older(obsolute backupsets) backupsets to the database. but when i do restore it defaulty takes latest backupsets other then obsolute onces.
how do i restore older(obsolute backupsets) backupsets to the database?
If i used the CHANGE cmd, how to do that.
RMAN> change backupset tag weekly_backup_20052013_02:45 _______________
do i make latest backupsets unavaliable to restore the older once....
RMAN> change backupset tag weekly_backup_20062013_02:00;
Thanks in advance...........
Obsolete backups are always usable, until you delete them with DELETE OBSOLETE.
If you want to restore from a backup other than the latest, use an until clause:
run {set until time = 'sysdate - 15';
restore database;}

Dear Experts
I am new in Database field please help me out regarding RMAN
Please guide me how can I achieve this
One thing I want to ask is ............ Minimum how much Databases (servers) required to achieve this?
-----------> I have a Dell machine and Oracle 9i Database on it on Windows 2003 Server
-----------> I want to Impliment RMAN on it
Please any one send me a simple document through whic I achieve my goal?
It would be highly appriciated

I'd suggest you to refer to the documentation

[Oracle9i Recovery Manager User's Guide|http://download.oracle.com/docs/cd/B10501_01/server.920/a96566/toc.htm]
As a first step, put the database in ARCHIVELOG mode, connect to RMAN and take your first backup as follows:
SHUTDOWN IMMEDIATE
STARTUP MOUNT
ALTER DATABASE ARCHIVELOG
ALTER DATABASE OPEN Then connect to RMAN from OS
[code
C:\rman target /
RMAN>BACKUP DATABASE;
That's all. By following above steps, you'll take your first backup. Then, read the manuals I've posted and start practicing
Good Luck

Rman backup level 0 doubt

Hi guys,
I have a doubt regarding Rman.
When I do a Level 0 backup (backup incremental level 0 database) it put in the file the empty blocks or
it saves only the used blocks in my database ?
I know the incremental backups (level 1 and 2) gets only the new blocks.
and I would like to know if rman files can be compressed during the process.
Thanks,
Felipe

Which is the version of its database?
If he will be 10g, sees the documentations.

Hi All,
I need details about some diagnostic test regarding RMAN backup on my instance.
The following are the current configuration of details:

Where is RMAN or backup/recovery sub-forum?

RMAN Priviligies and Role to Create backups

Hi everyone,
I have some questions regarding RMAN backup options in my mind and want your help in their clarification.
1) We want to taken backup of Database with RMAN and for that we want to create a new Database user to take the backup rather than sys user. For this what prives this users need other than connect, quota etc. What we want to do is that we want to ensure that this RMAN user can only take backups and nothing else. I've read in the documentation that in order to take backup through RMAN ; the RMAN users must have sysdba role. Is this necessary? Don't you think this can compromise the db security?
Kindly note that currently we are using control file as RMAN repository so no need the discussion of Recovery catalog in our case.
Regards,
Kamran

All RMAN database connections require SYSDBA privilege. So if you are using any other user other than SYS then you should grant it SYSDBA privilege.
