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
Thanks & Regards Neeraj

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 Speed

Hi All,
Our Database size is 1.3 TB and we take RMAN backup but it takes around 48 Hours to do backup in oracle 9i and in oracle 10g offers block compression can this help to reduce the backup time.

Trace dumps when performing RMAN backups

Hi,
10g release 2
I'm not very experinced with oracle 10g, but on 9i I've never seen this before:
Every time i do a RMAN backup errors is written in the alert log pointing to the instances' trace file in the udump dir.

to me it looks only informational, but i was wondering if anyone been experiencing similar behavior before, and if there are a way to avoid this? or is this an error i should take action on.
any ideas would be very much appricated!

This is a known bug # 4596065 with RMAN when controlfile autobackup is on and flash recovery area is enabled. Workaround is to ignore the trce files.

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;"

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.

Problem in recovery from RMAN backup in case of disk failure

Hi
I have Oracle 9.2.0.1.0 on Windows. Full Hot RMAN backup of database is scheduled on daily basis. I am taking backup on disks. And then i do manually copy them on tapes. If any disk failure occurs than can i recover database completely in this scenario. If tried restoing that backup on different machine as given below
set ORACLE_SID=<name>
rman target sys/<pwd>@ORACLE_SID nocatalog
startup nomount
restore spfile
create pfile from spfile
startup nomount pfile
alter database mount
restore database
Everything worked fine till above steps. Now i will execute last step.
recover database
Here it gives error:-RMAN-06054: media recovery requesting unknown log: thread 1 scn 264750
Still i typed
alter database open resetlogs
Now i can open my database, But is it recovered completely? Or there is loss of some data? Why it is giving this error?
Thanks in advance. Waiting for reply.

I can understand the confusion with this whole concept.
What I meant by all archivelogs is all the archivelogs that were backed up with the backup itself. Again, it is essential to ensure that you archive the current redo log AFTER the backup is performed and then back those archivelogs too. Good thing is, RMAN will take care of this for you if you backup the archivelogs with the BACKUP DATABASE command and/or backup the archivelogs AFTER you run the BACKUP DATABASE command.
Once you've mounted the controlfile and CATALOG the archivelogs, you can go into SQL*Plus and issue the following query:
select SEQUENCE#, FIRST_CHANGE#, NEXT_CHANGE# from v$archived_log
order by FIRST_TIME;This will tell you what archivelog is the latest. Logs generated during the backup may also provide the necessary information. Performing Disaster Recovery should help to understand the full process.
The ONLINELOG directory in FRA is only populated if you've configured your redo logs to be stored there. However, you are on 9i...right? If so 9i doesn't utilize a FRA.

Hi;
Our backup policy should have 7 days; however we have here some files from JAN, FEB,MAR, APR /2012 WHICH ARE BEYOND THE RETENTION DATE and these files should be deleted by executing " delete noprompt obsolete; ".

Rman backup archive log

Hi Guys,
Can advise on the syntax to perform rman backup of archive logs generated in last 2 days?
Should it be 1 or 2?
thanks!
1. BACKUP ARCHIVELOG UNTIL TIME 'SYSDATE-2';
2. BACKUP ARCHIVELOG FROM TIME 'SYSDATE-2';

What prevents you from trying both?
I'm not trying to be difficult here but why take the time to ask people in a forum, not even supplying a version number, and not just find out?
It took me less than 60 seconds to cut-and-paste both of your command lines into RMAN and look at the output.

Restore RMAN Backup

Dear All,
I am practicing Oracle Restore scenarios on my Oracle 9i database. Once I complete my tests in Oracle 9i I will move up to 10g and then finally to 11g.
Following is my recovery scenario:
1) I did NOT configure Recovery Catalog
2) I would like to restore my databse from a 15 days old backup
3) control_file_record_keep_time is set to 7 days.
4) Backups are on tape.
Can you guys please shed some light on how to I proceed?
- P

In oracle 9i , check , which situation you can perform complete recovery and in which situations you have to select incomplete recovery.

Need inputs on RMAN Backup n Recovery for multiple restore of clean backup

I will explain my scenario below:
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
Please suggest me the best way forward...
Many Thanks
Nukesh

Hi Asif,
I tried to make it work but seems there are still issue with my recovery, can you have a look and point out the shortcommings. i am totally lost here

Taking daily rman backup of archivelogs

Hi,
Technical info:
OS: Windows 2003 EE
DB: Oracle 10g EE v. 10.2.0.3
DB size: 30 GB
I need help to create a rman script or suggestions for creating a Job in Grid Control.
I want to take a daily (monday to friday) rman backup of archivelogs in the time interval 9 AM to 5 PM. The script should be run every 2 hours. I want the script to remove the archivelogs that are older than 4 days. The retention policy is 9 days.
Any suggestions will be very much appreciated.

Hi,
Yes, I have realized that I can create different jobs in Grid Control one for each day and each time: for example: at 9 AM, 11 AM, etc until 5 PM.
Each job performs a backup archivelog and removes those backups that are older than 4 days.
But I have to create 25 jobs (5 jobs for each day).
Is there a simpler way to achieve the same result?

Restore database to another host - I have only rman backup files

I want to restore/recover this RMAN backup to other PC.
I know the commands, restore database, recover database,
but I've always used these commands with rman into existing rman
user. Now, I don't have anything. I have only the RMAN backup files.
How can I restore/recover database to other PC using these files?
The steps are? create other database, create a rman user, register
the rman backup files in this new rman, and restore these files
in this new database already created with the same name?
thank you!!!!

RMAN backups need info about available options

Hi All
In our new 10.2.0.3 RAC environment on windows 2003 os we have our database configured on ASM and oracle home placed on OCFS. As it is a prod environment, we do not have the comfort to shutdown the cold copy of the database and so we're running the daily rman full db backup .. however, in case of an event where the datafiles need a restore.. I am not sure if the rman backup i take will be sufficient.. I issue the below command to take the full database backup and I get a compressed back up set..
RMAN> backup up device type disk format 'd:\database\%U' database;
I do have the FRA configured on ASM DG but i see that this DG is almost free. could any please advice what are the options available for me to take the entire database backup (including files) which can help me restore the datafiles if necessary.. my database is about 70GB in size but is very critical for organisations functioning..
thanks!
Sarat.

Thanks for the quick reply steve and werner...
Because we are doing a daily Full database backup (compressed) I did not include the archive logs to be backed up. In our environment, we keep moving arc logs to another archive location regularly. and once back up is complete and successful we clean up all archives using another job as we no longer would need them in case if we need to restore from the RMAN backup.. and as we retain all archives between one rman bkp and the next one.. we are also not backing up these along with the database.. Is this dangerous? I thought we will always have one database copy (compressed) available on disk and can help us restore from it if required.. But my major concern is what if a datafile is accidentally deleted/ disk fails on ASM. In this case.. the RMAN backup will not be sufficient because if cannot create the physical structure.. in such a case, will configuring the FRA it self be sufficient? Do I need to perform any additional steps to ensure the physical structure can also be restored? Please advice..
rman is configured to backup control file and sp file and my exact script looks like below .. and we run it every day
crosscheck backup;
crosscheck backup of controlfile;
delete force noprompt obsolete;
delete backup;
backup device type disk format 'D:\oracle\DBBackUp\%U' database;
exit;

RMAN backup on the physical standby database.

Hello,
11.2.0.3 EE database. Is it a requirement to open the database in read only mode in order to take a hot backup?
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
SQL> ALTER DATABASE OPEN READ ONLY;
I've initiated a rman backup without opening the db in read only and the following output is so far:
RMAN> backup format '/dbstor2/LTS/LTS_rman/%d_set%s_piece%p_%T_%U' check logical database plus archivelog;
Starting backup at 15-OCT-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=603 device type=DISK
specification does not match any archived log in the repository
backup cancelled because there are no files to backup
I plan on taking this backup and using it to refresh our Dev and QA dbs. Do you see any issues with taking a backup without opening the db in ready only mode?

No we are not using Active Dataguard. An issue I am investigating is why can't I perform an archivelog backup from the standby?
RMAN> backup archivelog all format '/dbstor2/LTS/LTS_rman/arc.rman.bak';
Starting backup at 15-OCT-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=603 device type=DISK

Finished backup at 15-OCT-12
