Tuning RMAN backups

Hello,
Would someone help me with the RMAN configuration for backup to disk? I am new to RMAN so I have no idea. Below is my database configuration.
Windows 2000 SP4
Oracle9i binaries on C:\ drive
Database (datafiles) on D:\ drive
Logs on E:\ drive
I have a total of 5 datafiles with approx. 400GB total. I would like to use RMAN to backup my database to disk in a SAN. The D: and E: drives are using RAID5. If I want to run the backup database in RMAN, the default is used. I guess my question is, how do I list all the default settings in RMAN and how do I optimize RMAN to backup my database (i.e. multiplex, number of channels, MAXOPENFILES, FILEPERSET, disk buffer, etc...) and the actual RMAN commands to perform these tasks.
Thank you very much.

Once in RMAN, you can execute the following to see all the default settings:

RMAN backup performance tuning

Hi All,
We have oracle 9iR2 two nodes RAC on solaris 9, I am looking for some helpful material on RMAN backup performance tuning, though i went through oracle's official RMAN performance tuning guide, still if there is some really nice material please let me know!
TIA

Oracle Material is the best.
Anyway, the one given below is also a good P&T book.

RMAN Backup is very slow

Recently we have enabled RMAN in oracle database 11gR2.
We are using Oracle secure backup 10.4, solaris 10 and SL24 tape autoloader.
We have performed full database backup with size 610GB using RMAN to tape and it took 7hrs to backed up.
Could you please advice me how to fine tune the performance of RMAN.
Thanks in advance,

Alter system flushed shared pool in RMAN backup

Hi,
I am trying to take RMAN backup of 11.2.0.1 Database in IBM AIX 6.1 server.
The RMAN is hanging .
Though the backup gets completed, The channels allocated doesnt get released and the RMAN gets hanging.
In earlier RMAN backup Scripts,
the DBA was using alter system flush shared pool in RMAN backup script and the backup was getting succesful.
Now my question is , is using ALTER SYSTEM FLUSH SHARED POOL have any performance impact on the database.

TEJAS

This may have a good impact if you had some fragmentation in there, or it could be mildly bad if everything was well sorted, or it could be very bad if you are unlucky or have some pattern of invalidations or should be pinning something or who-knows-what. It generally is considered not a good thing to do as a habit. You wind up with [url http://tkyte.blogspot.com/2012/05/another-debugging-story.html]rainy Monday scenarios.
Edit: I notice there are some bugs, including very slow performance when using a catalog. When you say hang, how long are you waiting? Have you considered current patches?

RMAN BACKUP PERFORMANCE.

Hello Sir,
Oracle Version : 9.2.0.1 /10.2.0.1
Operating System : ANY
This is just for knowledge :
What will be the performance issue if I have more than 1db (for example 10 Dbs.) and I start RMAN backups of all Dbs simultaneously and only the default channel to disk is being used ?
If there is any performance issue i.e. slowdown, what will be the best remedy for that and how ?
Please guide

How can i do a RMAN backup of my database from the network ?

i'm using oracle 8i.1.7.3 with win server 2003
i want to know how can i do a RMAN backup of my database (sever machine A) from the network.
i'd like to save the backup in another machine (the same LAN, the same OS ).
to do that i've mapped a logical device in my comptur (z):
when i run rman command i got this error:

Hi,
ORA-19504: failed TO CREATE file "\\remote\save\"make sure you have created this directory and change it's ownership (chown command)to oracle.
also make sure that oracle user has permission to write to this direcotry (chmod command)
hope this helps

Can not recover table from rman backup

For testing I want to recover deleted table from rman backup.
I have make vm of oracle 11g. the following step i have applied but could not recover the table.

On sqlplus create login as scott/tiger
create table scott.emp1(col1 varchar2(10));
insert into emp1(col1) value('Yasir ') ;
commit ;
select * from emp1 ;
it shows me one row successfully.
Now i have login the sys as sysdba
sqlplus> alter system switch logfile ;
after this i have drop the table .
Now to recover the table i have restored database on same vm.
rman>restore database ;

Unable to restore and recover my Database from RMAN Backup

Dear All,
Iam practicing RMAN in Windows environment.
My configurations are
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION ON; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:\Backup\%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'E:\ORACLE\DATABASE\SNCFORCL.ORA';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'F:\Backup\%U.bak';
Then i took the RMAN backup, now iam shutdown my DB and removed one logfile..
then i tried to startup the DB but it is saying
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: 'E:\ORADATA\ORCL\REDO03.LOG'
So i tried to restore the Database with my rman backup
RMAN> restore database;
But i am unable to restore my logfile in the Datafiles location where as all other datafiles are restored but redo logfiles are not restored.
So, i am unable to recover my DB
Please tell me whether i am doing any mistake, what is the solution for my problem.
Thanks in advance
Mahi

All you restored was your datafiles.
Now issue recover database and that will apply the archive logs.
This is in the oracle documentation.
"You must restore backups of these archived logs for recovery to proceed. You can restore either to the default or nondefault location. If you do not have backups, then you must performing incomplete recovery up to an SCN before the first missing redo log and open RESETLOGS."
http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/osrecvry.htm
In this case after issuing restore database in RMAN, then issue this.
"Recover database"
It will then be an incomplete recovery. They should have been multiplexed. Did you restore your controlfile with this backup? You may have to issue an "Alter database open resetlogs;"

Create a new Database in an other server using a copie of RMAN backup

Hi all,
I want to create an other instance for our production database. We have disk and tape in rman backup. My question is can i create a new database using our disk backup in an other server?
If some procedure or steps is there, email it to my adresse [email protected]
Hamid.
Thanks

By means of the use of Recovery Manager it is possible to duplicate a database out from a previously taken rman backup. The method will be outlined in the next few lines.
Let's assume a source database named SRCDB and the target database, named GEMINI. A unix like environment is assumed, but it can be implemented on windows as well, just beware of the particular Oracle implementation on a windows platform (orapwd file name, service creation, path format)
1. Create a password file for the Cloned (GEMINI) instance:
orapwd file=/u01/app/oracle/product/9.2.0.1.0/dbs/orapwGEMINI password=password entries=10
2. Configure tnsnames.ora and listner.ora
Properly identify the database at the tnsnames.ora and have the instance manually registered against the listener.ora files, both files located at the $ORACLE_HOME/network/admin directory.
2.a Manually register the database against the listener (listener.ora)
(SID_DESC =
(ORACLE_HOME = /u01/app/oracle/product/9.2.0.1.0)
(SID_NAME = GEMINI)
2.b Added the target GEMINI to the tnsnames.ora
GEMINI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost.mydomain.com)(PORT = 1521))
(CONNECT_DATA =
(ORACLE_SID = GEMINI)
2.c Reload the listener
lsnrctl reload
3. Create a new init.ora for the cloned database.
Next create an init.ora file for the cloned database. In case the same paths cannot be used on the target host, either because it is the same source host or because those paths are not reproducible on the target, then DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT may be required to be defined
DB_NAME=GEMINI
CONTROL_FILES=(/u02/oradata/GEMINI/control01.ctl,
/u02/oradata/GEMINI/control02.ctl,
/u02/oradata/GEMINI/control03.ctl)
# Convert file names to allow for different directory structure.
DB_FILE_NAME_CONVERT=(/u02/oradata/SRCDB/,/u02/oradata/GEMINI/)
LOG_FILE_NAME_CONVERT=(/u01/oradata/SRCDB/,/u01/oradata/GEMINI/)
# block_size and compatible parameters must match those of the source database
DB_BLOCK_SIZE=8192
COMPATIBLE=9.2.0.0.0
4. Connect to the cloned instance
ORACLE_SID=GEMINI; export ORACLE_SID
sqlplus /nolog
conn / as sysdba
5. Create an SPFILE based on the init.ora
CREATE SPFILE FROM PFILE='/u01/app/oracle/admin/GEMINI/pfile/init.ora';
6. Start the database in NOMOUNT mode:
STARTUP FORCE NOMOUNT;
7. Connect to the TARGET, CATALOG and AUXILIARY databases.
By means of the rman three connections are open, one for the Source Database (SOURCEDB), another for the Catalog database (RCAT), and one more for the cloned database (GEMINI)
ORACLE_SID=GEMINI; export ORACLE_SID
rman TARGET sys/password@SRCDB CATALOG rman/rman@RCAT AUXILIARY /
8. Complete or Incomplete clone (recover)
From the rman the database using one of the following commands:
8.a Clone the database by means of a complete recover.
DUPLICATE TARGET DATABASE TO GEMINI;
8.b Clone the database up to a defined point in time in the past by means of an incomplete recover
DUPLICATE TARGET DATABASE TO GEMINI UNTIL TIME 'SYSDATE-2';
9. Process finished.
Once the process is finished, the newly created GEMINI database is ready to be used as an independent new cloned database.

I am getting below error while taking RMAN backup.

Friends,
I am getting below error while taking RMAN backup.
The issue is related with a lock while trying to backup the controlfile.
The lock is more likely caused by the autobackup controlfile process started just before RMAN process was also trying the backup controlfile as shown in the following alert.log excerpt.

Creating a new controlfile with datafiles in RMAN backup

Hi,
i am using oracle 10g (10.2.0.1) in RHEL5 server. i am trying to restore a RMAN backup from one server to another new server with new db name. i have taken out the spfile from RMAN autobackup and created pfile from it and edited the pfile with new dbname and directory structure and started the db in nomount with the new pfile. Now i have restored the controfile from the RMAN autobackup tried to put the database in mount state. But it failed due to the below error
RMAN-03002: failure of alter db command at 11/05/2012 21:44:56
ORA-01103: database name 'ORADB' in control file is not 'DEVDB'
Hence i shutdown the database and started the db in nomount with new pfile and tried to create the controlfile with the new db name,but it failed as it is looking for the datafiles.
ORA-01503: CREATE CONTROLFILE failed

All my datafiles reside in my RMAN backup. How to get the datafiles from RMAN backup in the above scenario??

Hello;
The location and filename and DBIS will be different, but you need something like this :
$ORACLE_HOME/bin/rman << EOF
CONNECT TARGET /
STARTUP NOMOUNT;
SET DBID 3754763357; #DBID of PROD database
RUN
   ALLOCATE CHANNEL c1 DEVICE TYPE disk format '/u01/oradata/backups';
   RESTORE CONTROLFILE FROM '/u01/oradata/backups/sb_t790762003_s85_p1';
   ALTER DATABASE MOUNT;
   SET NEWNAME FOR DATAFILE 1 TO '/u01/app/oracle/oradata/CLONE/system01.dbf';
    SET NEWNAME FOR TEMPFILE 1 TO '/u01/app/oracle/oradata/CLONE/temp01.dbf';
   RESTORE DATABASE;
   SWITCH DATAFILE ALL;
   RECOVER DATABASE;
   release channel c1;
ALTER DATABASE OPEN RESETLOGS; So you need "SET NEWNAME" for all your files

is there any RMAN command to specify new DB name it should set while running

it appears to be i should not touch the soruce db.. i have access to only source db rman backups and need to create another db with different dbname/sid.. please do help...

When you performing RMAN duplicate why you making your script so complicated?
Your instance name and DB name can be different, But what is the contents in your pfile "D:\TESTDELETE\initclonedb1.ora" ? please do post
Have you started any other services related to ORACLE? check in start --> run --> services.msc any other active oracles services, Make sure you have clonedb1.
Startup in nomount
check the connectivity to target server.
SET NEWNAME FOR TEMPFILE 1 TO 'F:\app\HOME\oradata\clonedb1\TEMP01.DBF';Why you mentioning SET NEWNAME FOR DATAFILE ? You have option of db_file_name_convert/log_file_name_convert in case if your file system different in Target & auxiliary.
BACKUP LOCATION 'F:\app\HOME\flash_recovery_area\orcl\'When you have backup in same location why you are mentioning this clause?
First run duplicate from auxiliary server as
rman target sys/*****@prod auxiliary /
RMAN> duplicate target database to "db_name";
Am not sure what you are trying to do. is it 11gR1 or 11gR2?
You have option of duplicate from active database without having backup also..
here some links please check it.

Hi,
Since the error ORA-19809 indicates the lack of space in flash recovery area during the media recovery, I suggested increasing the value of the parameter DB_RECOVERY_FILE_DEST_SIZE.
Yes, during the media recovery the RMAN will restore the archived log to the default destination (only if the required archived logs are not already on the disks).You can confirm the restore location of the archived log in RMAN restore log/destination specified by parameters log_archive_dest_1/db_recovery_file_dest.

I am not able to restore spfile from rman backup ;;;

Hi,
I would like to know few things
1. How are you setting the db_name ? you can set db_id at RMAN, how are you setting the db_name ?
2. Do you have any default init file at default location ? if yes, is the db_name parameter set correctly in that file ?
Since spfile is yet to be restored, you must set the db_name parameter correctly before you start spfile restore.This can be done with init file at default location which can even contain just one paremeter i.e db_name.

How to find out when last rman backup was made in 9i

Hello,
i have an oracle 9i database running on windows here. Is there a way to find out when the last rman backup was done with a sql query?
I would like to create a job inside the database that regulary checks if a rman backup ran sucessfully instead of using scripts in the operating system.
But i only know about commands in the rman utility (that i can not execute as a job, right?) - is something similar possible with for example sqlplus?

this gives some results, but none of the views begins with RC:
