I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.
Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it
However during restore I am getting
Quote:ORA-19870: error reading backup
Here are the session details
RMAN> catalog start with '/u03/oradata/db7fra';
searching for all files that match the pattern /u03/oradata/db7fra

We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands: run { set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')"; allocate auxiliary channel ch1 type disk; duplicate target database to testdb; } exit
Is there a way on how to let RMAN use the latest backup pieces instead?
I set 'maxopenfiles 4' when allocating channel to sbt in my products env, I got 2 backup pieces in one backup set because that tablespace has 7 datafiles. Other configuration is kept as default, such as no maxsize, no MAXPIECESIZE, and etc setting.
I read document from Oracle. It says:"By default a backup set contains one backup piece. To restrict the size of each backup piece, specify the MAXPIECESIZE option of the CONFIGURE CHANNEL or ALLOCATE CHANNEL commands. " And also, maxopenfiles configure does not force another backup piece generated. So, why do I get another backup piece?
BTW, I tried this on another testing environment. I only get one backup piece even there are more than 2 times maxopnefiles datafiles.
Is there any way I can get all the archive log files present in a backup piece. I tried following but it always gives me all the log files for each piece:
**** SQL> select s.set_stamp, s.set_count, s.PIECES, s.backup_type, s.controlfile_included from v$backup_set s, v$backup_piece p where s.set_stamp=p.set_stamp and s.set_count=p.set_count and p.handle='5mjv4do0_1_1';
During the scheduled backup we observed that, backup got failed. Error is "ORA-01115: IO error reading block from file 11 (block # 118736) ". unable to rectify it. Below are the part of log file -

This is development server. Dont have RMAN configured.But when we connected to RMAN and issued block recovery, it started process and shows media recovery done. Since no RMAN backup was taken before, what it does here?

As I understand we can't clone database across platform using Rman, as Rman backup taken on say Unix is useless to be recovered on Windows. Though I think of Export and Import, will copying the datafiles, logfiles, controlfile will serve purpose for cloning across platform?
Note that I do not mean Transportable tablespace here. Only copying cold backup across platform
I have facing problem while taking backup on Windows 7 client of Oracle 11g R2 database. I have installed oracle 11gR2 for windows on windows 7 machine. I have created a directory like below in database.
On Database Server
SQL> create directory win_expdp_dir as 'd:expimp';
Directory created.
SQL> grant read, write on directory win_expdp_dir to lab;
Grant succeeded.
On Windows 7 machine (client machine)

We are trying to restore a database to a cold backup DBID.However while our datafiles were backuped up for 6 months retention we found out subsequent delete obsolete command wiped out the Control file related to this backup piece..Now what is left with this backup piece is just datafiles..
Can we still recover the database with a subsequent controlfile autobackup for the same DBID.?

New to oracle FAQ. I'm interested in oracle, waiting to explore more Technic's in 10g with a proper guidance. Hope i'm in the right place.Here is my question.
I need steps for configuring rman cloning with catalog & without catalog.were in prod db the source is in /u01 & in auxiliary db the client want in /u05. how to do it. here i have recreate control file or not
Oracle 10.2.0.5Linux 5I am creating a duplicate database using RMAN based on Oracle's documentation. I was successful up to running the duplicate command.Here is my command:DUPLICATE TARGET DATABASE vlab pfile='/<complete path of pfile>'; When I run the command, it tries to read from the backup files on production database - which is on anotehr node.Before then, I had backup piece copied to the node with the duplicate database.I ran this command to catalog the backup piece:catalog start with '/<complete path to backuppiece>'Error: no files to be unknown to the database On the other hand, when I run the command without cataloging the backuppiece, I get this error:

We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in: //192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod Instance created -- I created the relevant folder hierarchy under <ORACLE_BASE> directory -- Then, I created the relevant directories for Oracle Database, as follows: --a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK - INCR_MTDPROD_20110621_480_7.BAK And only see these two files: - C-2169285856-20110527-03 - C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 0 format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_
[code]....
This is the backincr.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 1 cumulative format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANINCR_ %d_%T_%s_%p.bak'
run { CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dd_oraback/tkprod/%F'; CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 22 DAYS; sql 'alter system archive log current';
[code]...
So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.
i have a task to do do a sanity backup just to check the backup is recoverable or not , but i failed to install the agent in my server due to we have a HP DATA Protector for a backup and my manager told me i need to take the backup from HDP not as i always do take the backup on disk and then move this backup on test server and do a task cloning ,i do the cloning by rman but the backup on tape drive , i mean by rman open a channel to take the backup from PROD to TEST?

diagnose what actually occurred during RMAN backup?
I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?
