Oracle RMAN backup to disk on vbox4.2 shared folders

[https://forums.virtualbox.org/viewtopic.php?f=7&t=53683]
Cross posting a virtualbox forum post in case someone has this working.
[posting snippet]
Anyone successfully using Oracle 10.2/11.2 RMAN to backup to mounted vbox guest shared folder? I'm thinking there may be some special configuration requirement like there is with NFS share mount options.

Hi,
never tried it, but I know that the shared folders in vbox don't work like normal filesystems.
I would rather setup an NFS server on the host and mount an NFS share in the guest.

A backup of under 2 minutes . . . not very big.

I don't think that is your problem . . . I think you need to check and see if your tapes are valid. If Oracle fails at the end of a backup to tape, it sounds like the tapes are 'bad'.
If the tapes are good: Then look at why it is so slow - I would 'guess' network backup.

RMAN backup to disk vs tape

AIX R 2
Oracle: 10.2.0.4
I have been testing rman backup strategies on a db in noarchivelog (development) using the following command:
(*) note: if db is in noarchivelog then you must do a cold backup - have the db mounted but not opened.
rman> backup database format '/a010/d01/bck/%U'
I have found that rman will backup to disk about 2GB per minute. Now I want to test this to tape to compare metrics.
Question: What configurations does RMAN need to write directly to tape?
What are the backup steps to write to tape? Do I need to specify both the tape channel and also where the format output gets written?
Thanks all.

OK
You need to install the Oracle driver for Tivoli (optionally sold with Tivoli) and install that in your Oracle software tree.
Then you can configure your channels to write to tape (this is documented).
For the rest there is no difference, although there are no directory names.

RMan Backup to Disk Options

Hello,
In Oracle 8.17 on Sun using RMan with a FULL DATABASE backup to Disk can someone please explain:
1. How to specify a tablespace(s) to NOT backup?
2. How to compress the RMan file during the backup (I am low on diskspace).
3. How to break the backup into two pieces and specify a different location for both?
I am not sure if the above are possible. Thanks for you help.
Thanks very much for your advice,
Michael42

Re your 2nd question :-
I've looked into RMAN and on the fly compression ( unix/linux).
It looks like it can't be done well not easily, ( check AskTom or dbForumns if you like).
Several others have tried and RMAN defeats you each time, the problem is that RMAN can't be made to write to STDOUT or STDERR or STD<anything> and thus any "on the fly" compression tools ie:gzip|bzip2| compress just doesn't get a chance at it.
If you are prepared to do some heavy scripting you can use a named pipe into a fixed file name and apply compression through the pipe, but it's a hell of a lot of work and there's a lot that can go wrong.
Re: Your 3rd question :-
Not sure that this will help you 100%, but it may give you an idea or 2.
I splice the DB backup like so; database on one volume and archivelogs on another as follows ...
run {
allocate channel ch1 type disk format '/backupdir1/b_%u_%s_%p.db';
allocate channel ch2 type disk format '/backupdir2/b_%u_%s_%p.arch';
sql 'alter system switch logfile';
set limit channel ch1 kbytes 1024000;
backup (database include current controlfile channel ch1);
set limit channel ch2 kbytes 1024000;
backup (archivelog all delete input channel ch2);
I also limit the size of the pieces.
Hope you get your problems sorted.

RMAN Backup to Disk in a RAC cluster...?

We have a two-node RAC cluster, using Linux and ASM. Pretty typical setup.
We are backing up to disk via RMAN. Right now, that filesystem is mounted on node #1. It's a SAN volume but is not presently clustered.
My questions...
(1) Is it best practice that only one node out of the cluster performs the backups?
(2) Or is there a config where all nodes participate in the backup?
My concerns are what happens when node #1 fails (presumably we'd have to mount the volume on node #2), and also the asymmetrical load during backups.
Thank you!

Hello;
Managing backup and recovery for RAC databases is no different from managing those for single-instance databases.
RMAN backs up the database not the individual instance.

RMAN backupsets to disk - how to parallelize?

Is there any way to utilize Oracle RMAN backup parallel features via BR*Tools when performing backup to disk?
Platform: Windows if it is relevant, Oracle 10.2.0.4.
The only way I found so far is to use exec_parallel parameter in BRTools profile and in this case parallelizing done via starting n processes of RMAN in parallel when each makes backup of separate datafile. The aim is to do something with BRTools parameters to get parallel option 'inside' RMAN (equivalent of "RMAN> CONFIGURE DEVICE TYPE disk PARALLELISM n;").
The other part - how to parallelize offline redo log backups for RMAN backupsets? Even having exec_parallel parameter set to >1 only one process of BRARCHIVE is processing all offline redo logs serially.
BR*Tools parameters which I changed from baseline:
backup_mode = full
backup_type = online
backup_dev_type = disk
archive_function = save_delete
disk_copy_cmd = rman_set
rman_compress = yes
rman_cross_check = arch_force
exec_parallel = 4

Hi Vladimir,
>> Well, BRARCHIVE does support rman backupsets; not directly through command line parameters but via parameter file.
You need to use external backup library in order to use backupset by BRARCHIVE with the parameter "rman_filesperset" in init<DBSID>.sap. Please check the link;
http://help.sap.com/saphelp_sm32/helpdata/de/82/29e03a00281877e10000000a11402f/content.htm
>> Is there a way to create disk RMAN backup via External Backup Library?
Are you asking this for BRBACKUP or BRARCHIVE? First of all, you can the note "1101530 - Support for RMAN savesets for backups on hard disk"

Oracle RMAN and SAP Databases

Hi all,
Am mainly an Oracle DBA and had just recently return to supporting SAP customers after a 4 year absence of supporting non-SAP customers.
Anyway, I have some question on using Oracle RMAN with SAP databases. Backup softwares are Netbackup and Data Protector.
I managed to get the backup working, that is, there is no issues, Oracle RMAN backup using SAP's brarchive and brbackup works alright. My question is about using an Oracle RMAN catalog. I've read thru several SAP documentation and cannot find one where I can use a RMAN catalog.
Reading from
http://help.sap.com/saphelp_nw04/helpdata/en/d1/43d7cab9a04a409cc46876e36762c2/content.htm
Does that mean I cannot use a RMAN catalog? Had anyone managed to use a RMAN catalog to do the RMAN backup?
*Another question I have is, do I need Netbackup and Data Protector if I want to run RMAN backup to disk via brarchive and brbackup? Does backint requires a SBT library to use RMAN? What I mean is, I want to use RMAN but doing backup to disk instead of to tape which means I don't need the tape library installed, will backint know that this is the case and will not look for the tape library?
Any advise or feedback on this will be very much appreciated. Thanks in advance.
Extracts from http://help.sap.com/saphelp_nw04/helpdata/en/d1/43d7cab9a04a409cc46876e36762c2/content.htm are as below:
The Oracle Recovery Manager (RMAN) is an Oracle backup program. You can use it as a command line interface (CLI) or as a graphical user interface (GUI) in the Oracle Enterprise Manager (OEM). We support RMAN with the SAP backup tools BRBACKUP and BRARCHIVE.
RMAN uses the System Backup to Tape (SBT) interface to back up to tape devices. We implement SBT using the SAP backup library. External backup tools can implement this interface as a dynamic link library (DLL).
Integration
By integrating RMAN into BRBACKUP, you can add security and flexibility to important functions in existing backup strategies and tools:
· The recovery catalog is not used. The backup information is stored in the control file. After the backup, the control file is also backed up. In a restore, the control file is restored first, followed by the data files.
· The integration of RMAN into BRBACKUP also guarantees integration into the SAP Structure linkComputing Center Management System (CCMS).
· BRBACKUP tape management functions as previously (that is, as when using the SAP backup library).
· You can still use the BACKINT interface with external tools.
· All previous SAP backup strategies are supported while using RMAN. Nevertheless, RMAN is not supported for standby database backups and split-mirror backups.
· The following components are delivered with the standard Oracle8 installation:
¡ RMAN with the Oracle SBT interface
¡ Backup library and backup tool Networker from Legato
¡ Legatou2019s BACKINT interface implementation (as of Oracle 8.0.5)
The SAP installation also delivers the SAP backup library with BRBACKUP and BRARCHIVE.

Hi,
This question has been answered by Stefan Koehler. Not sure why the thread is not updated by his response. I am hoping to give him the max points actually.
It was a very good response which is as below:
Subject: Re: Oracle RMAN and SAP Databases
Message: Hello,
> Does that mean I cannot use a RMAN catalog? Had anyone managed to use a RMAN catalog to do the RMAN backup?
Correct - if you are using the BR*Tools and RMAN you are not able to use a RMAN catalog with it.
You can do manual catalog syncs, but the BR*Tools are not supporting a catalog database.
>Does backint requires a SBT library to use RMAN?
Check this documentation (Point "RMAN Backups Without Backup Library"): http://help.sap.com/saphelp_nw04/helpdata/en/3f/9d800e1aec11d2b42c00609419997a/content.htm
> Any advise or feedback on this will be very much appreciated.
We are also using RMAN for taking backup of all our oracle database (SAP and non-SAP), but without any BR*Tools.
That is also possible - check sapnote #105047 (Part "50. Recovery Manager (RMAN)").
As you mentioned, that you are a fulltime DBA you should have enough knowledge to use RMAN without BR*Tools.
Regards
Stefan

When using compression, you will need to actually test to see which backup compression gives you the best compression/performance. Higher compression = slower performance, Lower compression ratio = more performance.
To make your life a lot easier when trying to do backups, make sure you do rman backup to disk, then sweep these backups to tape. The restore would then be much faster.

RMAN Backups residing remotely

Oracle Version: 11.2.0.3 x64
OS: Win 2008 server x64
Hi Experts.
We need to replicate a database on one of our boxes, with very limited space on disk. The database size is roughly 200gb, free space on disk is 250gb, and the RMAN backups are roughly 80gb.
The RMAN backup pieces have been cataloged with the following path:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'd:\rman\%d\bkup_%d_%U';So, if we attempt a restore/replication on the local server, RMAN would look for backups on the local D drive, under D:\rman\<db_name>\
In the past we used to copy the RMAN backups on the local server where the replication is required, and perform the replication locally without any issues; however, with a very limited space that won't fit both the replicated instance and the RMAN copies, we're not quite sure how further proceed!?
Can we instruct the RMAN replication session to look for backups in a remote server?
We do keep 3 weeks of RMAN backups on disk, hence the 80GB RMAN backups size. As far as I remember a full backup has been performed last Sun. Can we only bring over Sun full backup (and any subsequent incremental backups)? or do we need to copy the whole thing across to the local server?
Any ideas please?
Thanks

How to distribute RMAN backup among tape volumes in OSB

Hi Guys,
I would like to ask some information about OSB. I have finally set up our Oracle Secure Backup 10.3.0.3.0 and initial OSB backup to tape is good using our test environment.
Now, our production servers has the following details:
Serv01
- Oracle Database 11.1.0.7
- Windows Server 2003 R2
- Current RMAN backup to disk full (level 0) is at 2TB.
Serv02
- this is our media server for OSB and we manage from here all other servers that we would like OSB to be implemented.
-Windows Server 2003 R2
- We have IBM tape library here with four drives
- Our tape volumes are 480GB each (compressed) we about 50 of them.
-Each tape volume has barcodes and our library has barcode reader
How can I group certain tapes (as a media family?) and use them for our level 0 backup. As you know, one tape cannot hold our level 0 backup so we need at least 5 tape volumes to hold our level 0 backup. Is there a step by step process of doing this? Or does anyone know how to do this?
Thanks and I would really appreciate your thoughts about this.

Yes, media families (like tape pools) are used to group backups on tape. Using a database backup storage selector, you set-up media policy so OSB will automatically select appropriate storage when for the backup per your settings. You may want to refer to this white paper which discusses media management:

How to perform a Oracle-Offline-Backup started from within SAP in Cluster

Hello,
I didn't find a solution on web (at SAP/SUN/newsgroups) for the following problem:
environment
- offline-backup of Oracle-database (database of an SAP-R/3 ERP-system)
- Sun Cluster 3.1 environment (SUNW.oracle_server:3.1, SUNW.oracle_listener:3.1, SUNW.sap_ci_v2)
- backup should be started from within the SAP R/3 scheduler (SAP transaction: db13)
- Oracle-RMAN-backup with Legato networker 7.1
- SID of SAP-system: Q22
problem
When SAP starts the backup-job (scheduler: db13, type: Full database offline backup >> option: offline_force) the brbackup commands shuts down the database and starts RMAN-backup. But then the Sun Cluster sees that the database is down and starts it up. This action of the cluster crashes the backup.
Now I found a tricky solution for that problem:
1.
Install sudo because the following script will not be run as root...
2.
run visudo and add this line (the scheduler db13 uses the OS-user <SID>adm)
q22adm ALL=NOPASSWD: /usr/cluster/bin/
3.
make a shell-script which should reside on a global mount:
/sapmnt/Q22/MB/offline_backup_Q22.sh
#!/bin/sh
/usr/local/bin/sudo /usr/cluster/bin/scswitch -n -j Q22db-srv
sleep 10
/usr/sap/Q22/SYS/exe/run/brbackup -u / -c force -t offline_force -m full -p initQ22rmanoffline.sap
/usr/local/bin/sudo /usr/cluster/bin/scswitch -e -j Q22db-srv
4.
edit the table sapr3.sxpgcotabe in the Oracle-database and add an entry like:
NAME: ZOFFLINEBACKUP_Q22
OPSYSTEM: ANYOS
OPCOMMAND: /sapmnt/Q22/MB/offline_backup_Q22.sh
this is not possible via SAP, use Oracle-tools!
5.
edit table sdbac via SAP-transaction se16, select DBSYS=ORACLE and add an entry like:
SHORTCUT ZOFF
DBSYS ORACLE
OPSYS *
LANGUAGE E
SHORTNAM FullOffClu
LONGNAME Full database offline backup >SunCluster
HOST $DBHOST
CTYPE EXT
CNAME ZOFFLINEBACKUP_Q22
6. Schedule the offline-backup via SAP-transaction (new type available: Full database offline backup >SunCluster)
I hope that maybe helps someone...

RMAN Backup Strategy Comment Needed

Hi,
Currently I'm trying to implement a backup strategy with RMAN.
Scenario: My side we're 5 days operational (Monday to Friday). I'm planning my backup as follow:
Mon – Incremental level 1 differential
Tue – Incremental level 1 differential
Wed – Incremental level 1 cumulative
Thurs – Incremental level 1 differential
Fri – Incremental level 0 (aka full database backup)
I planned Mon,Tues and Thurs as an incremental differential, while Wed as an incremental cumulative. With Wed as a cumulative backup, my thinking is that if my db is to fail on Thurs/Fri, my recovery will need to apply fewer backups but at the expense of storage.
Any comment or view about the strategy will be greatly appreciated.
Thanks and Regards
