Best pratices for RMAN backup management for many databases
Dear all,
We have many 10g databases (>40) hosted on multiple Windows servers which are backup up using RMAN.
A year ago, all backup's were implemented through Windows Scheduled Tasks using some batch files.
We have been busy (re)implementing / migrating such backup in Grid Control.
I personally prefer to maintain the backup management in Grid Control, but a colleague wants now to go back to the batch files.
What i am looking for here, are advices in the management of RMAN backup for multiple databases: do you guys use Grid Control or any third-party backup management tool or even got your home-made solution?
One of the discussion topic is the work involved in case that the central backup location changes.
Well... any real-life advices on best practices / strategies for RMAN backup management for many databases will be appreciated!
Thanks,
Thierry

Thanks for your reaction.
So, i understand that Grid Control is for you not used to manage the backups, and as a consequence, you also have no 'direct' overview of the job schedules.
One of my concern is also to avoid that too many backups are started at the same time to avoid network / storage overload. Such overview is availble in Grid Control's Jobs screen.
And, based on your strategy, do you recreate a 'one-time' Oracle scheduled job for every backup, or do your scripts create an Oracle job with multiple schedule?
You're very welcome!
Well, Grid Control is not an option for us, since each customer is in a separate infrastructure, and with their own licensing. I have no real way (in difference to your situation) to have a centralized point of control, but that on the other hand mean that I don't have to consider network/storage congestion, like you have to.
The script is run from a "permanent" job within the dba-scheduler, created like this:
dbms_scheduler.create_job(
job_name => 'BACKUP',
job_type => 'EXECUTABLE',
job_action => '/home/oracle/scripts/rman_backup.sh',
start_date => trunc(sysdate)+1+7/48,
repeat_interval => 'trunc(sysdate)+1+7/48',
enabled => true,
auto_drop => false,
comments => 'execute backup script at 03:30');and then the "master-script", determines which level to use, based on weekday from the OS. The actual job schedule (start date, run interval etc) is set together with the customer IT/IS dept, to avoid congestion on the backup resources.
I have no overview of the backup status, run times etc, but have made monitoring scripts that will alert me if/when a backup either fails, or runs for too long. This, in addition with scheduled disaster/recovery tests makes me sleep rather well at night.. ;-)
I realize that there (might be) better ways of doing backup scheduling in your environment, since my requirements are so completely different than yours, but I guess that we all face the same challenges in unifying the environments as much as possible, to minimize the amount of actual work we have to do. :-)
Good luck!

WHAT IS BEST STRATEGY FOR RMAN BACKUP CONFIGURATION
Hi all,
my database size is 50GB I want TAKe WEEKLY FULL BACKUP AND INCREMENTAL BACKUP
WITHOUT RECOVERY CATALOG.by follwing commands
weekly full database backup
run
backup as compressed backupset
incremental level=0
device type disk
tag "weekly_database"
format '/sw/weekly_database_%d_t%t_c%c_s%s_p%p'
database;
I want do CONFIGURE RMAN BY FOLLWING stragtegy
CONFIGURE RETENTION POLICY TO REDUNDANCY window of 14 days.
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO
'\SW\AUTOCFILE_'%F';
and other is by default
sql>alter system set control_file_record_keep_time=15 days;
os--aix6 and for two database 10g2 and 11g2
what is best configuration strategy for rman backup.AND BACKUP WITH RECOVERY CATALOG OR WITHOUT RECOVERY CATALOG
PLEASE TELL ME
Edited by: afzal on Feb 26, 2011 1:45 AMFor simply two databases, there really wouldn't be a need for a recovery catalog. You can still restore/recover without a controlfile and without a recovery catalog.
From this:

CONFIGURE RETENTION POLICY TO REDUNDANCY window of 14 days.I am assuming you want to keep two weeks worth of backups, therefore these:
alter system set control_file_record_keep_time=15 days;
CONFIGURE RETENTION POLICY TO REDUNDANCY window of 14 daysShould be:
RMAN> sql 'alter system set control_file_record_keep_time=22';
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14;22 would give you that extra layer of protection for instances when a problem occurs with a backup and you want to ensure that data doesn't get aged out. -
RMAN script for hot backup (looking for code critic) code attached.
Hello Guru's,
I have been having soem trouble running a successful hot full rman backup nightly.
We max our CPU load whenever our RMAN takes too long and conflicts with a Legato tape backup. I have a development server that I attempted to get a consistent backup time duration that is rock solid as to not conflict with the Legato backup time.
I just found out about duration with RMAN scripts here is my code:
#!/bin/bash
#rman backup script for daily hot whole database backup
at -f /hd1/rman_scripts/rman_backup 0600 tomorrow
rman target/
run {
allocate channel d1 device type disk format '/path/%U';
backup duration 1:00 partial minimize load database filesperset 1;
backup as BACKUPSET tag '%TAG' database;
backup as BACKUPSET tag '%TAG' archivelog all delete all input;
delete noprompt obsolete;
release channel d1;
exit
It completes the backup, but does not use the 1 hour allocated- it only uses 15 minutes on average and creates many files instead of normally three backup files.
Here is the results from querying the v$rman_status table for operation,status,start_time:
RMAN,FAILED, 17-OCT-06 0600
BACKUP,FAILED,17-OCT-06 0600
RMAN,FAILED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,COMPLETED,17-OCT-06 0606
BACKUP,FAILED,17-OCT-06 0615
RMAN,COMPLETED,17-OCT-06 1513
REPORT,COMPLETED,17-OCT-06 1513
DELETE,COMPLETED,17-OCT-06 1513
However, the timestamps of the backupset files it creates is:
06:15 and not 1513?????????????
RMAN appears to have only taken 15 minutes to create the files, why do I have a completed timestamp from v$rman_status of 1513???
Please advise and comment, I am just learning RMAN.Try to remove the DURATION option in your script.
Here more details about that part.

Volume Duplication Policy for RMAN Backups
Hi,
I wish to configure a volume duplication policy for RMAN backups. Both the source media family and duplicate media family are 'content managed' as per the documentation. However, the duplication policy 'trigger' is defined as if the media family is 'time managed', which does not seem to make sense in 'content-managed' media families used by RMAN.
Does anyone have any guidelines on how RMAN volume duplication can be set up so that my duplicates are valid?
ThanksYes. I understand. The reason I used time-managed volumes in the tutorial is that with time-managed volumes a duplicate may have different retention and rotation than the original. The procedure for time or content managed duplicates are the same.
A content managed tape may be duplicated to the same or different media family. If to a different media family, the retention would be same...since content managed but it could have a different rotation policy...if desired. For example, if you wanted original tapes left onsite but the duplicates to go offsite for "x" time, then create a new content managed media family and a desired rotation policy...associate that rotation policy to new media family and duplicate tapes to that media family with desired rotation policy. In that scenario, your original media family would have a duplication policy and possible a rotation policy. The new media family would just have a rotation policy.

Choice a remote drive for RMAN backup
I want to use my AIX (OS 5.3L) as a remote server for RMAN backup, under the 10g R2. The two most likely drives that still has lots space are hdisk1 and hdisk3. However, the hdisk1 is in rootvg with my test Oracle 10g appl on. Although the hdisk3 is in appvg and but it is the data storage for oracle of local machine. Both drives are quite busy based on the memory monitor and iostat. so How to make a choice for which drive is more proper as a remote drive?
As i play more with the NFS on AIX, i noticed more about the user/group attributes of the files and directory. Mainly, they are different on either side, even more strangely that the new file created on the server side has different user/group attribute , not as oracle/oinstall of original (client side) It worries me whether there will be problem when RMAN does the recovery later.
Secondly, the NFS only allows to write into one level of the directory, which is assigned NSF. As I know, the whole RMAN backup creates backupset files at several levels down from my flash_recovery_area.

Hi,
on 10G R2 in AIX 6.1
I'm looking for Shell script for RMAN backup.
Moreover , if we should connect like this :

RMAN backup in ORACLE RAC database
Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,

RMAN Backup specially for tablespaces
Hi@everybody,
we have a Oracle 11gR2 (11.2.0.3.0) Server, based on RedHat 6, running in our company. For the Backups i'm using RMAN with a script. In that script this code specially creates the backup:
run {
allocate channel oem_backup_disk1 type disk;
backup incremental level ${level} cumulative as COMPRESSED BACKUPSET tag '${tag}' database;
backup as COMPRESSED BACKUPSET tag '${tag}' archivelog all not backed up;
release channel oem_backup_disk1;
${level} is for 0 or 1, full backup or incremental backup. ${tag} is the name for the backup. This script is for the hole database. But now i want to change that script to tablespace level. We have some "test" tablespaces, where a backup is not needed. I just found that one:
backup tablespace TEST tag='BACKUP_TEST';
But now i'm not shure how i can implement that into my script.
Can you guys help me?
Thanks and best regards,
DavidI've just to ask again to understand it right:
In RMAN - Console i just exclude the tablespaces that should not be backed up with:
CONFIGURE EXCLUDE FOR TABLESPACE Tbs1, tbs2, tbs5;
And then RMAN knows, when he is doing a backup of the database, he will exclude that tablespaces that i've told him? Thats awesome! And easier to handle!
EDIT: I've tested this on my Oracle Test server and it works! Thanks a lot for the answers! -
kindly send the script for RMAN bacup

Best Practice while configuring Traffic Manager for Azure Website
Hi Team,
I want to understand What is the best practice while we configure traffic manager for Azure website.
To give you the base, Here let me explain my requirement. I have one website which 40% target audiences would be East US, while 40% would be UK and rest 20% would be from Asia-pacific.
Now, What I want is Failover + Performance based Traffic Manager Configuration.
My thinking:
1) we need to create 1 website with 2 instances in each region (east us, east asia, west us for an example). so, total 3 deployment of website. (give region based url for the website)
2) create traffic manager based on performance and add 3 of those instances. that would become website-tmonperformance
3) create traffic manager based on failover and add 3 of those instances. that would become website-tmonfailover
4) create traffic manager and ?? don't know the criteria but add both above traffic manager here and take your final url for end user.
I am not sure (1) this may be the right approach or not (2) if this is right, in the 4th step which criteria we should select while creating final traffic manager round-robin/ performance/ failover?
after all these if use try to access site from US.. traffic manager will divert that to US Data-Centre or it will wait for failover and till that it will be served from east-asia if in configuration, east-asia is my 1st instance?
Regards, Brijesh ShahHi Jonathan,
Thanks for your quick reply. actually question is bit different. Let me explain you different way.
I was asking for recommendation from Azure Traffic Manager team. whether my understanding is correct or not.We want Performance with Failover.
So, One azure website we have: take an example todoapp. I deployed that in 3 different region. now, I want to have performance based routing as well as failover based routing. but obviously I can't give two URL to my end user. so, at the top of that I will
require one more traffic manager. So,
step 1: I will create one traffic manager with performance criteria named: TMForPerformance.trafficmanager.com where I will add all those 3 instances (all are from different region so, it want create any issue.)
step 2: I will create one more traffic manager with failover criteria named: TMForFailover.trafficmanager.com where I will add all those 3 instances (all are from different region so, it want create any issue.)
step 3: I will create one final traffic manager with performance criteria named: todoapp.trafficmanager.com where I will add these two traffic manager instead of 3 different region's website.
Question 1) Is it correct structure if we want to achieve Performance with Failover or Is there any better solution?
Question 2) in step 3, what criteria we should select? performance/ round robin/ failover

User Permission for RMAN Backups
Oracle 10g Database Enterprise Edition R 10.2
I have created a user admin and i want to run backups from admin user. Kindly let me know what user permissions i have to grant for rman successful backups?
Thanks!The rman "client" executable must connect to the Database AS SYSDBA.
Therefore, technically it doesn't require a separate user account in the target database, although you could setup a user, grant SYSDBA to the user and have remote_login_passwordfile configured to allow connections.

Write a ms dos script for rman backup
Hi all,
i wanna write a dos batch file to take the rman backup..
i have written one...actually there are 2 files. one is for login purpose...other one is for sql commands
rman.bat-->
rman target sys/sysadmin@hnbhrm @'c:\rm.sql'
==============================
rm.sql-->
configure retention policy to recovery window of 7 days;
configure controlfile autobackup on;
run {
alter system switch logfile;
crosscheck archivelog all;
crosscheck backupset;
backup database plus archivelog;
DELETE NOPROMPT ARCHIVELOG ALL COMPLETED BEFORE 'sysdate -1';
DELETE NOPROMPT OBSOLETE REDUNDANCY = 1;
========================================
but i have problem in first file rman.bat. it doesnt run at all. but if i write sqlplus / as sysdba instead of rman thing.. then it works fine.
can anybody tell me whats happening over there please..? Have i done this correctly? or u have some other simple way to do this...
both files are located in C drive.. and oracle is installed to E drive... oracle path has set already.
can anybody please give me a hand to solve this issue please...
Thanks in Advance,
Maxwrite a ms dos script for rman backupImpossible. rman does not support MS-DOS. It is not a 16bit real mode application that can be run inside the MS-DOS operating system.
So get your terminology straight - the Windows console is a character based 32bit virtual machine. It is not MS-DOS. It never was MS-DOS. Do not confuse the two simply because of superficial similarities. A stick-it note can be yellow - but because it is yellow does not mean it is a banana. -
Rman backup size for Dr db is very much higher than that of primary db
Hi All,
My production database on Oracle 10.2.0.4 had a physical size of 897 Gb and logical size of around 800 Gb.
Old tables were truncated from the database and its logical size got reduced to 230 Gb.
Backup size is now 55Gb which used to be of 130 Gb before truncation.
Now this database has a DR configured. Backup of this DR database is daily taken which is used to refresh test environments.
But the backup size for DR database has not decreased. The restoration time while refreshing test environments is also same as before.
We had predicted that the backup size for DR database will also decrease and hence reducing the restoration time.
We take compressed RMAN backup.
What is the concept behind this?When you duplicate a database it will restore all the datafiles from the RMAN backup. You will find the physical space of your source database. Remove the fragmented space using object movement. Then shrink the tablespaces and take fresh RMAN backup and restore.

RAC RMAN BACKUP Recovery FOR Oracle APPS Application
Hi,
We have an Application which is similar to Oracle APPs application and We have a RAC Database at Backend.
As I am a Oracle RAC DBA and never worked as an Oracle apps DBA.
Each Week or month We have to deploy a patch on Our Database which are kind of sql changes to Database and before we applying we need to backup our Database.
I am very comfortable while applying patches on Single instance Database:-
I Usually shutdown my database and backing up My Database(Conistent\cold Backup) before applying patch.
and I have a Flash back on both option I am having for my Database.
Problem:-
But in Production I have RAC Database, on which I already configured Hot Backup.
FlashBackup Feature is there with me, but Not reliable.
I want cold backup along with my existing hot backup, and want to restore same if something goes wrong.
Since ASM is configured so we have only option RMAN backup.
IF possible kindly Share your knowledge and Experience of your to handle Such Problem.Sir,
RMAN is already configured for backing up database online.
My only intention is to have cold or consistent backup before applying application patch, So that at the time of crisis I will resotre my Cold/Conistent backup.
Because I am using 11gr2 RAC with ASM, so only option is there for me to use rman as backup tool.
But I never tried to Have Cold backup in RAC environment in my previous jobs, and I am new to this Oracle APPS DBA technology. So Here I am looking for a Strategy that Normally oracle apps dba use while applying patch to Oracle Database and kind of backup strategy they use.
