Backup & Recovery :: RMAN Duplicate Set Until Time Using Wrong Backup Piece Name To Restore?
Feb 26, 2012
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?

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:

But when I try to restore the spfile to a pfile:

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_

We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.

I am attempting to use an rman backup form our live server to restore live data over an existing dev database with a different name. I cant use the duplicate command as the versions of oracle are different (10.2.0.4 EE on live, 10.2.0.5 SE on dev) So I copied the backup sets including an autobackup control file onto the dev server. I set the ORACLE_SID to the DEV version (SUN43DEV) and startup nomount and restore controlfile from the backup location. This works and restored the live controlfile. However, I then wanted to mount the database and catalog the backupsets before making a note of the last archivelog etc and restoring the backup with set newname options. But when I try to mount the database I am told that the database has a different name (SUN43 is not SUN43DEV). I read somewhere that I need to set the ORACLE_SID to the live value (SUN43) and restore as that, then use nid TO RESET THE DBID and DATABASE NAME. However, my tnsnames on DEV has no entry for the live database, and we do not have any service defined through ORADIM for the live instance on the dev server. Should I be creating an entry in DEV tnsnames that actually looks at the LIVE server? or do I need to create a service and tns entry etc for SUN43 on my DEV server pointing at the DEV server I have not seen any mention in instructions of creating a service or adding the entry to tnsnames, or indeed adding an entry to the listener for the original live sid. I am worried that if I actually point to the live server then the restore would be attempted on the live server not dev even though I am running it from Dev.
Also, do I need to drop the existing database on DEV before I restore or will RMAN just restore over the top of it?
Finally, if I try to add an entry to the LISTENER.ORA for the new sid, when I stop and start the listener, or reload, the entry is not recognised. I also noticed that the existing SUN43DEV entry is not in there either, yet I can still use that SID - I am assuming that is because the listener is not being used and the sid is recognised from the existence of the service in windows services instead?

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

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.

First I installed linux on same network, I gave it access to cifs backup resource, then I installed the same database version than production environment, then I create a typical database with only same database production name. Also the Linux partitions between linux servers are different.

My scenario is: database is in archivelog mode.
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried:
startup mount
restore database from tag 'DLYTUE'
recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE'
( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.

I have a doubt regarding the process the RMAN follows for restore and recovery of the database.
My Level 0 full backup completes on Saturdays at around 11 am after taking 8 hours (It starts at 3am).On Sunday, I ask RMAN to restore (on a different box) till Saturday 11:30 am.Then, after the restore is successful, I recover it till 11:45 am.
The recovery also goes fine and Iam able to clone to test box.
Till what time is the database restored? I assume its till 11 am since the L0 backup finishes at 11 am though I have asked it to restore till 11:30 am
During the recovery, ONLY the archives generated between Saturday 3 am and till the time i asked for recovery (Saturday 11:45 am ) are required. But, checking the recovery log file, i was surprised to see that RMAN has restored archive files starting from Friday 9:30 pm (Much before the time the Level 0 backup even started).
why does RMAN require the old archive log files.

I want to restore my database from server x to server y.
The control files on server x are named [$ORACLE_SID]_control01.ctl and [$ORACLE_SID]_control02.ctl.
We have an auto backup of the control files.
When I restore the control files on host y, (from autobackup) the restored controle files have other names: control01.ctl and control02.ctl. After the restore and recover (which goes well) the database does not start correctly.

Oracle 10gR2 (base)
Dataguard, no RAC
no ASM
Performing backups on the physical standby via RMAN. We need to restore our test database, and right now it is equivalent to the production. The DUPLICATE command seemed the best bet. We have controlfile and SPFile both on Auto-backup, and the RMAN on a six day retention with weekly 0 level backups and nightly level 1 cumulative backups.
However, when I run the DUPLICATE it chokes being unable to find a current controlfile nor one in backup, even though we have six days worth of supposedly good (validated) backups. We are not using a catalog, rather the DB controlfile.
The solution to this error is reopen the database and try again. however, the physical standby cannot be opened. It is the standby. What if we move the last backup to the primary database, "register" it there, and try this DUPLICATE?
I have seen nothing on this in my searches, and the Oracle documentation does not address this, though it recommends backup from the Physical Standby.
RMAN-05513 is the error code.

1. My RAC (old RAC) had got a failures from one node, then there was only one existing node now.
2. I configured a RAC (new RAC) on 2 other servers, both of them (old-RAC and new-RAC) has got same OS version, platform and Oracle version release.
3. I took a full backup yesterday plus archivelog in the node of old-Rac, configure NFS in new-Rac to make the backup within remote-share NFS.
The only problem still now that I've restore/recovery/duplicated single instance, not Rac. So, may you guide me to do it?

TRACE 0;
setlimit channel ch1 maxopenfiles 8;
backup
incremental level = 0
filesperset = 32
database
include current controlfile spfile ;
}
exit;
These backups done successfully.Then archivelog backup taken similar way.But when I issue RESTORE DATABASE PREVIEW SUMMARY; RMAN starts with Full backup set, though newer Incremental Level 0 ones are available.Why it does not use these newer ones?
