RMAN backup problme becasue of TSM

I Joined one call today , topic was RMAN backups problem because of TSM, I am wondering what is TSM, i guess Tivoli Storage manager...Not sure, and how it can effect RMAN Backup & its performance...Just trying to get general idea....

Yes, TSM is Tivoli Storage Manager which is IBM's backup/recovery/storage management product. RMAN needs a media manager interface to write to tapes, this is where TSM comes into play. It acts as this media manager passing off the data to write to tape. This is made possible via a library which TSM provides (an Oracle library link file is replaced with one pointing to the TSM library file) to inform RMAN of it's presence and enable it's use. There are also configuration settings (network timeout, throughput, client name, media server name, etc.) which to a great deal affect the performance of RMAN and TSM to the extent where backups may not be possible if setup incorrectly.
For more information you can look at the IBM site.
Hope this helps.

RMAN backups are slow with TSM

Hi,
I encountered a problem using RMAN with TSM to backup a database. It seems that the RMAN channel doesn't use the entire bandwidth to the TSM (or whatever) and is idle most of the time. This makes the database backup really slow.
As a comparison, we backup also filesystem and SQL Server, they both use very few channels and each channel backup about X5 more data per second than Oracle. For example, SQL Server uses 5 channels to the TSM, and we get a total of around 100MB/s. When we configure Oracle to backup using 5 channels we get about 20MB/s and we see that the SQL Server is writing to the TSM all the time while Oracle is idle a large portion of the time.
Any ideas? Known configuration issues?
I hope I'm clear about the problem.
Thanks,
Liron

Hi,
Thanks for everybody for your responses, I'll try to sum the answers here:
1. Yes, we backup the filesystem, and everything works fine. The problem is only with RMAN backups
2. Resources are not an issue, it happens on strong and weak servers (and several O/S as well)
3. Database versions are not the issue, it happens on 10.2 as well as 11.2
My feeling is that this has something to do with the integration, either oracle setting or TSM setting, but I can't be sure until I solve this.
For those of you who backup with TSM, did you notice that filesystem / SQL Servers are being backed up faster? Did you check the Oracle wait events and TSM status while you run the backup?
Thanks
BTW Girish, great comment, I wish I had all the answers... :)

RMAN Backup to TSM

I am looking into Oracle Database which use RMAN backup directly to tape (TSM). Before I never worked with TMS (Tivoli) and looking for simple command which I could run from UNIX prompt to see what is available on tape what files, directories…
Any help would be appreciated.
My Oracle version 8.1.7 and OS: AIX

Unfortunately there's no 'simple command'. You have to study the documentation for this TSM API:

Rman backups slowly

Hi,
We backup our oracle database to tsm server using rman through TSM. The backup takes about 3 minutes. Topas shows that the disks containing datafiles are very busy(about 90%), Readch is about 160m, top processes are lrud and aioserver. lrud process takes up about 20% cpu.

But if we backup the database to local disks, the backup lasts only 1 minutes. Topas shows that Readch is about 30m.

*Slow RMAN backup and restore using TSM [ID 1072800.1]*

Is it possible to restore TSM/ADSM RMAN backup pieces to disk manually?

Is it possible to restore TSM/ADSM RMAN backup pieces to disk manually, and re-catlog as disk backups?
Oracle 10.2.0.3
TSM client 5.5.1.1
SUN Solaris 10 64-bit
We are gearing up to switch from IBM's Tivoli (TSM/adsm) to EMC's Networker (Legatto), and the old TSM software drivers are going to be uninstalled.
In a worse case scenario, we would therefore not be able to easily restore using RMAN and TSM just after the switch, and before new backups are made on Networker.
To be comfortable with the backup methodology change, we need to explore restoring the RMAN backup pieces of a given tag using TSM commands (dsmc ?) to a filesystem, re-catalog the backup pieces now on disk, and then perform test restore/recoveries using RMAN with disk channels.
Does anyone know of the TSM command (dsmc ?) to perform the restores of RMAN backup pieces?
Thanks!

This is a set of guesses and thoughts.
1: When you say you are removing the Tivoli software drive, is this just the driver from the oracle home, or is it more substantive. In fact could you have a different oracle home to access tivoli, possible with a rman catalog copy.
2: I dont believe the backup tag is part of the filename, however is it possilbe to query the rman catalog to get the filenames mapped to a tag?
3: Providing you know the filenames you wish to restore then it is possible to browse the tivoli catalog. Its ages since I've done this but doesn't samc have at interactive mode
Apologies if these suggestions are rubbish and hopefully someone gives a better answer.

RMAN backup and TSM question

We have rman backup file name contains the datetime so it is unique and easy to tell. But TSM keeps every file 4 versions, so the backup file (always 1 version because of unique name) will stay on tape forever. I have no idea about TSM, according to your experience, what is the normal solution here?

Dedicated forum for {forum:id=74}.
But quickly, in general, "DBA" and "TSM/Storage manager" need to agree on media manager use and setup the system accordingly.

How to stop a rman backup in progress?

OS: AIX 5.3 L and Oracle 10g R2
I got panic when my scheduled rman backup (incremental level 0 plus archivelog) run too long and I want to stop the process. I could not find the rman doc mentioning how to use any rman command to do that, instead of just shutdowning the database instance.with ps -ef, there were just too many PID of oracle. Is there a way by rman to STOP the process?
Furthermore, I had no idea why it happened. Last week when I did a full copy backup, it only took 23 minutes for 32G database, Today, I changed the scheme to a level 0 incremental, and it is still running after 5 and half hours. But it already created the archivelog, datafile backupset (checked by the DB control). How to find out what went wrong?

I did not use any third party application with rman or TSM in my AIX. what is the tdpo? Killing at OS level is probably only thing I can do now. kill -9 PID#

RMAN backup in HP Ultrium 3-SCSI(3mn) tape device

Dear All
IS it possible to take online RMAN backup in HP Ultrium 3-SCSI(3mn) tape device?
Note: this is not a tape library, a stand alone tape device.
Thanks & Regards
Quazi Abdur Rab

In RAC, Please note that you can take backup from any node and you can able to restore from any node.
If you taking backup to disk then you must mount the same backup mount on both servers in order to able to backup and restore.
In your case you are taking backup to FRA and from there taking to tape.
The TSM wtih tdop agent is congiured on Node1 and not on Node 2 thats why you are not able to restore from node2.
27029, 00000, "skgfrtrv: sbtrestore returned error"
// *Cause: sbtrestore returned an error. This happens when retrieving a
// backup file during a restore operation.
// *Action: This error is returned from the media management software which is
// linked with Oracle. There should be additional messages which
// explain the cause of the error. This error usually requires
// contacting the media management vendor.
/u01/home/oracle:DBA>
If you restore from FRA or using RMAN both nodes know the backup location and able to restore.
Hope this helps,

Slow rman backup and slow database

Hello all,
Whenever I run rman backup to sbt_tape, the complete database becomes slow. Also RMAN takes more than 12 hours to complete.
RMAN script is:
run {

On my server, we needed to adjust the vmm on aix for oracle to run best. Before I did that it was really slow.
http://www.ibm.com/developerworks/aix/library/au-aixoracle/index.html
Specifically these as outlined in the document linked above:
Listing 3. Changing the default setting for the lru_file_repage parameter using vmo
root@lpar21ml16ed_pub[] > vmo -o lru_file_repage=0
Setting lru_file_repage to 0
root@lpar21ml16ed_pub[] >
Setting this to 0 tells the VMM that you want to steal only file pages and not computational pages. As this will change if the numperm < minperm or > maxperm, we will make maxperm high and minperm very low. Years ago, before the lru_file_repage parameter was introduced, we used to make maxperm low. If we did this now, we would stop the application caching programs that are currently running.
Listing 4 shows how we'll set these parameters:
Listing 4. Setting the minperm, maxperm and maxclient parameters
vmo -p -o minperm%=5
vmo -p -o maxperm%=90
vmo -p -o maxclient%=90
We also want to take a look at minfree and maxfree. When the pages on our free list fall below minfree, the VMM will start to steal pages, which we don't want to happen until the free list has beefed up the number in maxfree. The values should be similar to the ones shown in Listing 5.
Listing 5. Setting the minfree and maxfree parameters
vmo -p -o minfree=960
vmo -p -o maxfree=1088

ASM RMAN backup to File System

Hi all,
I have a rman backup (datafile and controlfile) which was took in an ASM instance (not a RAC) ORACLE 11.2.0.2 in a Linux server, now I want restore the backup in a new database in windows/Linux OS using general File System storage (single instance rdbms) instead of ASM.
Is this possible?
Can I restrore an ASM rman backup in a file system storage mechanisim in a new server?
Kindly clarify my question.
Thanks in Advance..

Hi Levi,
Thanks for your invaluable script and blog.
can you clarify me on this query:
I have a RMAN backup taken from ASM and the backup is database and controlf file backup which contains datafiles and controlfiles.
Now I need to restore this on my system and here I dont use ASM or archive log, I use single instance in no archive log mode database.
I have restored the control file from the RMAN controfile backup.
Before restoring the control file I have checked the orginal pfile of the backup database which had parameters like
'db_create_file_dest',
'db_create_online_log_dest',
'db_recovery_file_dest_size',
'db_recovery_dest',
'log_archive_dest'.
Since I am not gng to create a DB in no archive log mode, I didnt use any of the above parameters and created a database.
Now my question is:
If i restore the database and the datafile will get restored and after renaming all the logfiles, database will be opened.
I want to know whether this method is correct or wrong and will the database work as it was working previously. Or do i need create the db_file_recovery and other parameters also for this database.About Parameter:
All these parameters should reflect your current environment any reference to the old environment must be modified.
About Filesystem used:
Does not matter what Filesystem you are using the File (datafile/redolog/controlfile/archivelog/backuppiece) are created on Binary Format which depend on Platform only. So, The same binary file ( e.g datafile) have same format and content on raw device, ASM, ext3, ext2, and so on. So, to database it's only a location where file are stored, but the file are the same. ASM has a different architecture from Regular Filesystem and need be managed in a different manner (i.e using RMAN).
About Database:
Since your database files are the same even using different filesystem what you need is rename your datafiles/redofiles on controlfile during restore, the redo files will be recreated.
So, does not matter if you database are noarchivelog or archivelog, the same way which you will do a restore on ASM is the same way to restore on Regular Filesystem. (it's only about renaming database file on controlfile during restore)
On blog the post "How Migrate All Files on ASM to Non-ASM (Unix/Linux)" is about move the file from filesystem to another. But you can modify the script used to restore purposes;
## set newname tell to RMAN where file will be restored and keep this files location on memory buffer
RMAN> set newname for datafile 1 to <location>;
### swich get list of files from memory buffer (rman) and rename on controlfile the files already restored.

Rman backups delete

What commands would I use to do the following:
Daily I take a full compressed backup. I currently use:
backup as compressed backupset database;
And backup my archivelogs. I currently use:
backup archivelog all;
Then I want to keep 2 days of backup and archivelogs on disk and maybe 7 days of backup and backed up archivelogs on tape. How do I accomplish this part?

For what you are doing I like to utilize a storage manager product with my tape system where the files on disk are brought to tape automatically and stub files left in place where the files appear to be in the directory but are really on tape. This way I can just manage RMAN backup pieces and execute dsik based backups normally but manage my disk space better, manage RMAN as normal because as for as RMAN is concerned the files are there on disk. Tivoli Storage Manager (TSM) has a product that does this called HSM, other vendors have Hierarchical Storage Management (HSM) products as well. They are usually pretty inexpensive and remove complication related to managing the backup pieces between disk and tape with RMAN. You get the best of both worlds without having to manage anything differently then just disk based backups and you can use less storage.

Possible solution is:
The default path where TDPO looks at is '/usr/tivoli/tsm/client/api/bin64'
even if the file DSM.SYS exists in another directory.
The read permission of the file '/usr/tivoli/tsm/client/api/bin64/dsm.sys'
was incorrect:
-rw-r----- i.e. "OTHERS" which is Oracle isn't allowed to read the
file /usr/tivoli/tsm/client/api/bin64/dsm.sys
After changing permissions on /usr/tivoli/tsm/client/api/bin64/dsm.sys in order
to allow oracle to use it then the backup works fine.
$ chmod +r /usr/tivoli/tsm/client/api/bin64/dsm.sys
The problem is on the TSM side. If the solution does not work you have to check TSM logs for further error messages.

Reply from nagulan is correct. Our turned out to be an error with TSM. The disk pool had filled up and it was writing this to tape before allowing the backup to continue. The backup didn't handle the "pause" event well and failed out. We only get this with V9 RMAN, not V10 or V11 RMAN backups. This has to be addressed by the backup vendor for V9 as the Oracle RMAN software doesn't seem to handle it well. Maybe configuring a really large timeout for responses MAY fix this, depending on what the code returned from the backup software vendor is and why RMAN isn't happy with it.
In the end it is an issue between V9 RMAN and the backup software we run TSM. Maybe version incompatibility or maybe just V9 is not that robust.

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
