Implementing RMAN in 9i

Hi Team,
I am a new bie to RMAN concepts. I just went through basic concepts and tried to implement RMAN in one of my test server which is Oracle 9i.
I have given few configurations and executed the below command through RMAN prompt.
BACKUP
FORMAT '/opt/backup/RMAN/%U'
DATABASE;
This backed up all .dbf files successfully but its consuming space.
So, i need to try Compressed RMAN concept. Please let me know if compressed backup is supported in Oracle 9i.
If yes, Kindly give me the basic command to implement.
I tried the below command. But its throwing error.
RMAN> BACKUP AS COMPRESSED BACKUPSET DATABASE;
Please suggest.
Thanks,
Vidhya

Hello,
Oracle 9i does not support compressed RMAN backups. It came in as a feature from 10g.
http://www.oracle.com/technetwork/database/features/availability/rman-dataguard-10g-wp-1-129486.pdf
You can try zipping the backup pieces once the backup is completed in order to save the disk space.
If you feel that your question has been answered, then please consider closing your question by providing appropriate points.

Implementation of ORACLE9i RMAN physical standby database`

Sir's,
How to implement RMAN in the physical standby database

Hi Ashu Goel,
Can u let me know any thing abot the prerequistw of implementation with the configuration settings of the above said.If I understand you correctly you want to use rman to backup an already existing dataguard setup.
Doing this would be very similar as a normal rman backup with the limitation you have to stop the recovery during the backup window and run the backup in mount mode.
To make a consistent backup of the standby database, make sure that the last shutdown of the standby database was clean and that it was not placed in recovery mode after that time, and then mount the control file. For example:
sqlplus SYS/oracle@sbdb1 <<EOF
SHUTDOWN IMMEDIATE
STARTUP NOMMOUNT PFILE=initSTANDBY.ora
ALTER DATABASE MOUNT STANDBY DATABASE;
EOF
You can back up the standby database when it is in any other mode, but the backups will be inconsistent.
Start RMAN and connect to the standby database with the TARGET keyword (not the AUXILIARY keyword) and the recovery catalog database. You must be connected to the recovery catalog. For example, enter:
% rman TARGET SYS/oracle@sbdb1 CATALOG rman/cat@catdb
If do not have automatic channels configured, then manually allocate one or more channels of type DISK or sbt. Note that you are connected to the standby host, so the backups are made by server sessions on the standby (not the primary) host.
This example backs up all the standby datafiles as well as the control file and archived logs by using automatic channels:
BACKUP DATABASE PLUS ARCHIVELOG;

RMAN - Implementation

Currently we do HOTBACKUPs and EXPORT... Now I am planing to implement RMAN. Can you please check the below
steps and let me know what changes/steps should I further add in... EXCEPT RECOVERY CATALOG
RMAN> connect target sys@rock
target database Password:
connected to target database: ROCK (DBID=3255117147)
using target database control file instead of recovery catalog
1. Configuration
-1.a CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
-1.b CONFIGURE CONTROLFILE AUTOBACKUP ON;
I have created 3 batch files and scheduled it as below mentioned days.
2. LEVEL-0 BACKUP (SUNDAY)
-2.a rman_backup_incremental_Level_0.rcv
backup as compressed backupset incremental level 0 database plus archivelog;
restore database validate;
exit;
3. LEVEL-1 BACKUP (Wenesday)
-3.a rman_backup_incremental_Level_1.rcv
backup as compressed backupset incremental level 2 database plus archivelog;
restore database validate;
exit;
4. LEVEL-2 BACKUP (mon,tue,thu,fri,sat)
-4.a rman_backup_incremental_Level_0.rcv
backup as compressed backupset incremental level 1 database plus archivelog;
restore database validate;
exit;
-------------

Hi,
you must understand the concept correctly
CONFIGURE RETENTION POLICY TO REDUNDANCY 2
your retention policy to have to duplicate copies - to maintain for recovery purpose.When you ask the ORACLE with help of rman to report the obsolete, then it will check with the copies and retention policy and which are required like arch2 will be not be marked and displayed as obsolete
day1:- I have backup of database plus (arc1, arch2, arch3)
day2:- backup of dababase plus (arc4, arch5, arch6)
day3:- backup of dababase plus (arc7, arch8, arch9)
- The two recent backup will be available all other backups are marked obsolete/delete..
- arch2 and arch3 are in day1 backup, which is marked obsolete/deleteYou must check the type of backups you are taken in to consideration as given in day1, day2, ...etc.,

What are the caveats of using ASM as storage for RMAN backupsets?

Hello all,
We are currently evaluating RAC as our standard database platform. Until now we have been using 10g single instance with ASM for datafiles and local filesystems for RMAN backupsets and archivelogs. We chose to use local fileystems for backup components so that we can utilize a Tivoli filesystem backup in order to secure the backup pieces to tape.
With RAC, we are looking into a shared location for backupsets and archivelogs. OCFS2 is out of the picture due to it not functioning on top of linux LVM. It appears that our only "shared" option is to use ASM for backupsets and archivelogs.
My concern is that while the data diskgroups and rman diskgroups will be separate, they are both running on ASM and therefore if ASM fails or is corrupted, we have nothing. My current plan is to utilize the Tivoli RMAN MML (TDPO) to backup the backupsets to tape after the ASM backupset has completed.
What experiences have been had with using ASM for RMAN backups?
Any advice on additional protection we can employ to ensure that the database remains recoverable?
Thanks in advance,
David

I've personally haven't implemented RMAN with ASM, but you may want to review Faster Backup, Faster Recovery which discusses RMAN utilizing ASM.
And although you may not get any of the negative aspects from these presentations, you may want to check out High Availability Customer Case Studies, Presentations, Profiles, Analyst Reports, and Press Releases.
Hope this helps!

Rman level 1 is taking same time as level 0 in oracle 9i

Hi experts,
what is exact difference b/w incremental backup(level 1) in oracle 9i/10g,
out prod db is oracle 9.2.0.8,
we are planing to implement rman on production but we have tested one of test db,
but it has taken same time as full backup(level 0)..level 1 nothing but only changed blocks why it's taking same full backup time..
what is the main reason behind that plz help me .

Oracle 10g has block change tracking feature - a file that tracks all changed DB blocks is continuously maintained. That file enables RMAN (10g) to read only the blocks that have changes since the most recent full backup. The feature could bring huge performance improvements for incremental backups. A negative would be slightly slow down DMLs during DB operation.

Networker + RMAN

We are in process of implementing RMAN backup’s with networker. We have installed and configured mno module and have run the script manually and works fine. But when I schedule to run it from networker, I got a tns access denied problem because I had not put the user_name/password in the script and was using connect target /
Below is my script
Works manually
connect target /

allocate channel t2 type 'SBT_TAPE';
send 'NSR_ENV=(NSR_DATA_VOLUME_POOL=OracleDaily)';
backup database plus archivelog;
release channel t1;
release channel t2;
works only if I
connect target user/password@service_name
run {
set command id to 'networker_testdb_bkp';
allocate channel t1 type 'SBT_TAPE';
allocate channel t2 type 'SBT_TAPE';
send 'NSR_ENV=(NSR_DATA_VOLUME_POOL=OracleDaily)';

Also, to clarify, can anyone advise what happens when you give
RMAN> connect target / => as which user is the db connected to from RMAN ???
can anyone advise. thanks

connect target /
connects to the db defined by the ORACLE_SID in your environment, very different to connect target username/password@service_name.

Errors while using RMAN APM in Bakbone

I am trying to implement RMAN using Bakbone Netvault. The thing is I am able to take a backup without any problems. But when I try to do a restore to the DB from the Bakbone tool it is failing with the following error message. I am not sure what is going wrong.

Any pointers to where I am going wrong would be really helpful,.

Yes, it's solved. Sorry for the long delay in reply (Mike) - I'm not getting email notification of replies from the forum, even though I've set them.
As a solution, use disk2vhd instead of the SC12VMM P2V wizard, which will seemingly always fail in this situation in my hands.

RMAN pros and cons

Hey everyone,
We are implementing a new system, and are struggling to deterimine if it is worth while to implement RMAN. I know Rman can save us backup time and money (as you can perform incremental backups vs. full.. However in the past, I have run into issuse with restores/backups - and was told they were caused by RMAN issues.
Could anyone let me know if this RMAN is now stable, and if it is recommended? If we can handle the extra storage needed to do full online backups daily, is it still worth implementing rman?
Thank you everyone in advance for any info.
Kind Regards
Richard Rog

Hello Richard,
here is my personal opinion about RMAN.
Pro:
- automatic consistency check of the blocks (if DB_BLOCK_CHECKSUM is enabled)
- incremental backups are possible
- brtools support RMAN backups/restores
- block media recovery is only possible with RMAN (but you can use an old fashioned [non-RMAN] backup for this)
Con:
- RMAN requires CPU time while performing the backup
- RMAN compression is not useful if you write your data e.g. to LTO drives which perform compression "for free"
- RMAN is quite complex, so you'll encounter lots of new Oracle error messages

Mark

Backup procedure using RMAN for 11i Instance

Hi,
we have 11.5.10.2 instance
Node 1 = Application Tier ( 11.5.10.2)
Node 2 = DB Tier ( 9.2.0.7)
as of now, we are taking daily cold backup of both instances.
we want to implement RMAN online backup for DB and take cold backup every week end only.
so, what are the best procedures for implementing RMAN for 11i Database.
Please share your experience, if you have anybody implemented?
which one you prefer in RMAN backup ( backupsets or copy option or backupsets with compressed option) interms of performance.. our db size is 60 GB only.
we apply apps tier patches very rarely . so we want to take RMAN online backup for DB daily and take cold backup for entire apps and db in the week ends.

Hi,
This time, i am going to implement for Oracle 11i Database. thats why, i need you guys advice regarding 11i Database.Well, the same is applicable to 11i/R12 databases. You just need to configure RMAN the same way you configure it on any standalone database.
If you have implemented any where RMAN, can you share, how you are taking RMAN backup? I can share the scripts we use for backup using RMAN. If you are interested, let me know and I shall send it by email.
if we want to clone, are you cloning the TEST instance with RMAN backup or using cold backup.We use both, depends on the time frame of the cloning task and whether it is possible to use cold backup for cloning or not.
Please have a look at the following notes, it should be helpful.

RMAN and archivelogs

Hi All,
We are about to implement RMAN instead of brarchive/brbackup. For us the major disadvantage of using RMAN is the way it handles deletion of the archivelogs after backing them up to our TSM storage manager.
When using brarchive a single archivelog is deleted from the archivelog filesystem once it has been backed up to TSM, in this way freeing up space in the archivelog filesystem. When using RMAN the backed up archive logs are only deleted when the complete bunch of "to be backed up archive logs" are actually backed up to TSM. This would mean that if the archive log filesystem fills up (e.g. due to problems with our storage manager or heavy archivelog creation) the space in the filesystem is only freed after the complete RMAN cycle has finished. The database would be hanging untill that time. When using brarchive a single archive log will be deleted once it has been backed up, thereby creating free space in the filesystem immediately and the database to be running normally again.
In order to keep our systems running when the oraarch filesystem is filled up and RMAN is running we can increase the size of the filesystem untill the RMAN cycle has finished and the archivelogs are subsequently deleted. However we are wondering if there is any other way in which we can make sure that the system keeps running. E.g. is it possible to use an 'overflow archivelog filesystem" to which oracle switches once the initial archivelog filesystem fills up? Or any other method?
What's best practice for this?
Thanks.
Regards,
Bart Groot

Hello Bart,
i am sorry, but in your previous post you said that you want to "implement RMAN instead of brarchive/brbackup".
Now you are talking about the init<SID>.sap file again.
If you use native RMAN you have some backup scripts (for full backup, archive log backup, etc.) in which you can specify the FILESPERSET clause. If you still want to use the BR*Tools with RMAN (which uses the init<SID>.sap file) you can specify the FILESPERSET clause globally .. so it is used for archive log files and full backups, etc.
But as i already mentioned that should be no problem, because of in huge environments not all files should be in one backupset.

Backup with RMAN without BRBackup

Hello,
Actually backups on my production servers are performed using brbackup without rman.
I want to implement rman with a repository used by others oracle databases.
I would like to know if SAP supports database backups without DB13 and br*tools ?
Regards

Hi,
You can integrate RMAN into your Oracle database with the SAP System using one of the following:
○ SAP implementation
You can use the SAP implementation of the Oracle interface SBT, using the SAP backup library. For more information on activating the SAP backup library, see SAP Note 142635.
Hope this is useful.

RMAN change archivelog all crosscheck

Hi DBA's
I want to implement RMAN backup on a prod db for the first time. tha DB was running for more than 2 years and generated seveal archive logs. the previous dba was just taking a cold backup and move the archive logs to somwhere else.
i want to know if i issu the command "change archivelog all crosscheck" how long it will takes and how far it will go back to check the archive logs.
is it going to crosscheck from SCN 1 to current which is 189234 or just checks the necessary SCN numbers ?
Thanks

Hi,
Checks whether the specified backups and copies exist. If RMAN cannot find backup pieces, it marks them as having the status expired. It marks all other types of absent files--image copies and archived redo logs--as deleted.
If the files are on disk, RMAN queries the file headers. For other device types, RMAN queries the media manager to see whether the file exists in the media management catalog.
Note: RMAN considers archived redo logs as copies, so issue the change archivelog all crosscheck command if one or more logs become unavailable. If the archived logs become unavailable again, you must issue catalog archivelog to re-catalog them.
Note: If you crosscheck a control file copy, specify a filename rather than a primary key.

Removing disk backups after implementing Veritas tape backups

I was using RMAN with a catalog to backup to disk. Now we implemented RMAN backups using Veritas tape backup using the same catalog and I want to remove the old disk backups.
When I "crosscheck backup" and "crosscheck archivelog all" then "delete obsolete" it errored with the following:
==================================================================
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of delete command at 08/29/2005 13:53:39
RMAN-06091: no channel allocated for maintenance (of an appropriate type)
================================================================
I assume it is seeing one of the tape backups and wants to detete it.
How can I clearout these unnecessary disk backup sets without causing any problems?
Thank You,
.....Kevin

I found the solution:
RMAN> crosscheck backup;
RMAN> crosscheck archivelog all;
RMAN> delete obsolete device type disk;
-- Assuming redundency was 1 only one set is left in the disk directory...
RMAN> list backup;
-- Find the backup set key which lists the DISK backups.
-- List all the BSKeys
RMAN> delete backupset key1, key2, ..., keyn;
-- The files are gone...

Rman create some files and very big size

Dear all,
I was implement rman back up on windows 2003 R2 with oracle9i.When i ran script
for backup as below :
RUN {
allocate channel ch1 type disk;
CHANGE ARCHIVELOG ALL CROSSCHECK;
CROSSCHECK ARCHIVELOG ALL;
DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
BACKUP DATABASE PLUS ARCHIVELOG;
CROSSCHECK BACKUP;
DELETE NOPROMPT EXPIRED BACKUP;
DELETE NOPROMPT OBSOLETE;
RELEASE CHANNEL ch1;
EXIT;
During executed these script i found rman create some files the name is "CQISBDNR_1_1" and the size around 17 gb. @ "D:\oracle\ora92\database"
and my config as below :
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'E:\Rmanbk\CF%F'
CONFIGURE DEVICE TYPE DISK PARALLELISM 1; # default
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 'E:\Rmanbk\%d_DB_%u_%s_%p';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'E:\RMANBK\SNCFAPPR.ORA';
What happend ? and Pls advise !
Thanks for advance !
Chara

I don't see any thing wrong in having a 17Gb rman backup file. It is just your backup in a single piece. You have configured rman to use the maximum size possible:
BACKUP DATABASE PLUS ARCHIVELOG
and
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
As long as you have enough space to grow and you can transfer your backup piece to a safe place in a timely manner, you may cope with this.

Implementing Hot backup strategy

Hello everyone,
I am a newbie DBA and now working with an investment bank, their Oracle System is new and I am meant to to implement a backup startegy, the database is meant to be available 24/7, its oracle 9i on Windows Server 2003, it has got 25 tablespace and the data to be backed up is about 10GB.
I need advice on how to go about it, should I look into scripting or implement RMAN backup, because the backup has to be schduelled about midnight.
If scripting is the choose could someone advice because i don't know how to script.
Thanks in advance

If the data meant to be available for 24/7 , then you do not have any option , but to choose hot backups . Well I happene to be a great fan of RMAN and it's a great tool for backup and recovery purpose . As your database is not that big and it's only about 10 GB . you can consider hot backups through RMAN , as you want to backup it everyday , I would advise you to set retantion policy of 2 days.
rman > {
allocate channel device type disk ;
backup database ;
