RMAN backup files differences in numbers and sizes

hi,
I have cloned one database and after doing i can see the target (cloned database has more number of files and in different sizes).
i can see the scripts are the same and environments are the same..
where do i find out why there is difference between source and target ..
ulimit -a > is same
RMAN backup scripts > is same
any clues i can find out >?
Thanks.

hi,
Let me make it clear here
Cloning done well no issues..
now two databases A and B are seperate now.. functioning in two different serveres
The observation (not an issue) here is
Server 1 > the backup files generated by Database A is only 10 backup files (10 * 5 = 50 )
Server 2 > the backup files generated by Database B is 25 files.... (25 * 2 = 50 )
so how the differences came in both backup scripts are the same....
hope you got my concern...10 * 5 and 25 * 2
*5 and 2* are backup piece and *10 and 25* are backupset, yes?
From each server, post:

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; ".
All files are exist in /u15/rman/

How to find total size of RMAN backup files?

Hi there
env: Oracle 10gR2, RHEL 64bit
My client has a production database where rman backups are taken: Level-0 backup every Sunday and Level-1 Monday thru Saturday.
I have very limited access to this production database because it is being managed by third party and they won't provide me my required info (not sure why). I do not have access to their rman repository. To connect to the database I have to login to an intermediate server and then login to the database server. I have no access to Enterprise Manager. So in short, my access is limited. I want to gather the information on total size of rman backup files - both for a Level-0 and Level-1 backups separately. I understand that this info can be retrieved from rman repository. Are there any data dictionary views/tables where I may get this info?
Best regards

SQL to find rman backup files required for recovery?

Hi folks,
I'm looking for a sql statement that I can use to query the database and return a list of the RMAN backup files needed for a successful recovery based on a SCN or a point in time. I want to do it through SQL (not though rman) because I want to script an automated refresh process. My databases are backed up online, so I would need any archive log backups done during the database backup as well. So for example...
I do a database backup
Then do an archive log backup.
Pass a SQL script the lowest and highest scn numbers during the backup.
It returns a list of the rman backup pieces needed to do a successful recovery.
I've got a script, below, which shows the lowest and highest scn during the last full backup (all datafiles which exist have been backed up), if someone understands what I'm looking for and has done something similar, I would really appreciate any insight you may have. What I'd want to get back from the SQL is the names of the rman backup files (handles) which would be needed to get the database recovered to the highest scn during the backup.
SELECT MIN(VBD.CHECKPOINT_CHANGE#), MAX(VBD.CHECKPOINT_CHANGE#)
FROM V$BACKUP_DATAFILE VBD, V$DATAFILE VDF,
(SELECT
CREATION_CHANGE#,
MAX(COMPLETION_TIME) COMPLETION_TIME
FROM V$BACKUP_DATAFILE
WHERE CREATION_CHANGE# IN (
SELECT CREATION_CHANGE# FROM V$DATAFILE)
GROUP BY CREATION_CHANGE#
) QUERY1
WHERE VBD.CREATION_CHANGE# = VDF.CREATION_CHANGE#
AND VBD.CREATION_CHANGE# = QUERY1.CREATION_CHANGE#
AND VBD.COMPLETION_TIME = QUERY1.COMPLETION_TIME;
Thanks very much for your time,
-Adam vonNieda

In case anyone's wondering, here's the answer. The following query returns the min and max SCN numbers contained in the last online backup.
SELECT MIN(VBD.CHECKPOINT_CHANGE#), MAX(VBD.CHECKPOINT_CHANGE#)
FROM V$BACKUP_DATAFILE VBD, V$DATAFILE VDF,
(SELECT
CREATION_CHANGE#,
MAX(COMPLETION_TIME) COMPLETION_TIME
FROM V$BACKUP_DATAFILE
WHERE CREATION_CHANGE# IN (
SELECT CREATION_CHANGE# FROM V$DATAFILE)
GROUP BY CREATION_CHANGE#
) QUERY1
WHERE VBD.CREATION_CHANGE# = VDF.CREATION_CHANGE#
AND VBD.CREATION_CHANGE# = QUERY1.CREATION_CHANGE#
AND VBD.COMPLETION_TIME = QUERY1.COMPLETION_TIME;
This next one gets the session key for that backup.
Select distinct session_key from v$backup_datafile_details
where checkpoint_change# >= <min scn# from above> and checkpoint_change# <= <max scn# from above>;
And finally, this one returns all files written out during that RMAN session, which includes control files, data files, and archived redo logs
Select handle from v$backup_piece_details
where session_key = <session key from above> order by completion_time;

I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots. Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
See Pondini's page for more explanation: What are Local Snapshots? http://pondini.org/TM/FAQ.html
I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
You have tested the library on the external drive, and so your photos are save there.
The local TimeMachine snapshot probably now contains a backup of the moved library. Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

RMAN backup to write on tape and disk in the same time

Hi all,
I want to take backup using RMAN and to have the backup file in a tape and a disk, i know i can allocate channel for tape, or disk. My question is can i use the both disk and tape in an rman backup one time. I mean i want to have rman writing backup file in a local disk and a tape in the same time to have redoundant backup at a tape and local disk.
If some scripts is there, it will be welcome.

Oracle 9i RMAN backup filling up all disk and failing at the very end

Hello to all and thank you in advance for any input from any of you.
I am new in oracle and the only one in my company with a little bit of oracle knowledge, which is not a whole lot.
I inherited a few servers (Linux and Windows based). We mostly run all our production environment on a Linux box hosting oracle 10g release 10.2.0.1 but we had a legacy application server that still runs on 9i release 9.2.0.1.0. This server is a windows 2003 box, the previous DBA or someone else with admin rights to this machine compressed the whole drive where oracle resides, when I started summarying the oracle assets, I saw this server with no backups scheduled and a compressed disk with very limited space after this compression, only 13 GB left, the database if uncompressed would definitively filled up all the disk. The machine is in used and cannot be taken down for more than a couple of hours. We tried adding another disk but the machine only accept it as a hot spare. The database is in archive mode, when I tried to run a RMAN backup, it start filling up the database drive until it's empty and it crashes the whole machine, it seems like the buffer is growing and growing until it fills up the whole drive. The only way to get the server up and running again is to reboot the machine since the server is more than 6 years old we are not please with this action because we are afraid the machine would go south in one of those reboots.
Has anyone heard of similar issues when running RMAN on a compressed drive? Can the compressed disk have any involvement in this kind of odd behaviour? I tried running the backup in debug mode and creating a log in a different disk (the one where the backup is going to) and still the same issue. Again any help is much appreciate,
Sincerely,
Alex

Sybrand,
Thank you for your fast response, I am going to use your previous post to answer one by one your question,
1 The Oracle binaries --- on a compressed drive > Yes
2 The Oracle database control files redo log files and datafiles on that same compressed drive? > Yes
3 The archived redo log ditto? > Yes
I know for a fact (as I have been using that in 9i) you can create a RMAN backup on a compressed drive, and you can have your archived redo go to a compressed drive. No problemo! > Excellent good news!!!
But I would never touch the data files. Please note backup sets are multiplexed files consisting of multiple datafiles, so RMAN would need to do some calculations to decompress several blocks at the same time and to calculate a new block and compress it.
Do you have enough space to:
a) (preferred) to make datafile copies instead of a backup >
Not in the drive that hosts the oracle instance but yes on an external usb drive (1TB) I attached to use as a backup repository, maybe this is why I am having these issues. I only have 13 GB left on that drive where the oracle instance resides (actually as I explained in a previous reply to Mark, the server only has 3 slots for disks, two of them as configured as RAID 1 and the other is a hot spare because the RAID configuration manager cannot can only added as hot-spare. The raided disk are partitioned in two, one small partition is for the OS and the other is for the oracle instance). When you said make a copy of the datafiles, I assumed you are talking about doing manual backups, and copying the database after using using "alter tablespace tablespace_name begin backup; then copy the file; alter tablespace tablespace_name end backup;
b) use filesperset=1 on the backup command line, so the multiplexing (and associated calculations) stop. I have not tried the option of fileperset yet but I can tryi it and see if that helps.
Can you post the last few lines of the RMAN log where RMAN bombs out? Note: the last few lines. Not all of it, or you must send some paracetamol in conjunction! >
When I ran the debug option, I stopped the backup at less than 20% because I didn't want to reboot the system in the middle of the production time, the backup consumed at least 3 GB during the time was running. The times I ran the RMAN backup I didn't used the debug option so I don't have a log long enough to send unless you want the last few lines of what I have.
Thanks again for your input,
Sincerely,
Alex

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

Hi all,
The PC where Oracle was installed is crashed.
I have only the RMAN backup pieces in other computer.
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!!!!

I have the same problem. For about 1 month ago I extended my iCloud storage account (+20 GB) in order to maintain my backups for iPHONE and iPAD as my account would expire 14/10. In spite of this, I got an email 15/10, which said that iCloud was reduced to 5 GB. 2 hours later I received a new email with comfirmation on the purchase of +20 GB storage plan. However, I only have access to 5 GB on my iPad and iPhone. Called Apple Support but they couldn´t help me. Did you find any solution ?

Previous activities: Database dictionary was

database...
Enterprise Manager was reconfigure with create repos
due to same problems....I have not seen the full error messages that follows this one (post it if possible). However, if you recreated the database, then your database will now have a new DBID after it was recreated. You can see the current DBID of the database to see if it matches the one above.
If it is a standby database and it is logical standby, then it will also have a different DBID.

Hello,
Does anyone have good or bad experience storing RMAN backup files &
datapump or export files with CIO enabled jfs2 file systems on AIX 5.3 & Oracle
10gR2? Is that supported? Metalink and IBM documents are not very
clear about these files... i.e. it does not say anywhere it's
supported or not supported.. So asking here..
Thanks in advance for your answers.

Can anyone from Oracle comment on this?
Thanks,

The backup file contains unrecognized data and cannot be used

I am trying to restore files from an NT back up on a SBS 2003. The backup was taken on this machine and trying to restore to the same. I get this error: The backup file contains unrecognized data and cannot be used.
I tried copying it to a different machine with no luck. Any suggestions?
Robert

Hi,
Since the backup file cannot be restored on a different machine, the backup file could be corrupt. You need to use some third party recovery utilities to restore the backup file.
For more detailed information, please refer to the article below:

Why are my RMAN backup files still around?

Environment:

Michael,
I read Ed's thread and I understand about the timing of the Full (Incr Lvl 0) and the incrementals.
In my case I'm not doing any incrementals (Incr Lvl 1) of the database, just Incr Lvl 0 every day. I do the archivelog backups during the day to keep the /arch mount point under control.
So, if I have Incremental Level 0 backups on the 19th, 20th, 21st, 22nd, ..... With an 8 day recovery window I shouldn't need the ones from the 19th or 20th at a minimum and possibly the 21st depending on when the math is done. Right?
Am I missing something?
*************** NEWS FLASH ******************
Whoops!!! Egg on my face! I just checked back in my email logs of the backups and now recall there were some disk space issues around that time that caused the backups to fail and it just so happens that the backups on the 20th, 21st and 22nd all failed.
I should learn to trust RMAN more. It is obviously smarter than me!! :-)
Sorry for the red flags. I'll do my homework more completely next time.
Not a problem. We've all been there, done that.
I can't tell you how many times I've been stuck on something, run out of ideas on my own research and thrown a question to the forum, and no sooner to I hit the 'send' button that a light goes on and I quickly get my own answer.
At least I understand the recovery window scenario better.
Thanks very much for the help and I'll see you the next time.
Have a great day!

thank you!Instead of moving if you want to register those backups with your controlfile. (RMAN repository)
then
$rman target /
RMAN> catalog start with 'location';
It will search for backup pieces in that location, and it prompts you for confirmation with YES/NO.
Give yes, so that all the files will be cataloged, Later you can able to view in list backup.
HTH.
