May 13, 2012
my restore scenario bellow.
I have hot full backup that processed by NetBackup Policy. the backup policy are;
1.Full backup database in Monday. Daily_Monday_RMAN <- 1 volume pool=1 media
2.Full backup database in Tuesday .Daily_Tuesday_RMAN <- 1 volume pool=1 media
3.Full backup database in Wednesday. Daily_Wednesday_RMAN <- 1 volume pool=1 media
4.Full backup database in Thursday. Daily_Thursday_RMAN <- 1 volume pool=1 media
5.Full backup database in Friday. Daily_Friday_RMAN <- 1 volume pool=1 media
6.Full backup database in Saturday. Daily_Saturday_RMAN <- 1 volume pool=1 media
How to restore database from one of medias?

7 of days ago Full backup has been taken to disk due to issues with tape devices.3 days ago tape devices have been fixed and we switched to CommVault managed tape backups. CommVault calls RMAN with following command:
run {
allocate channel ch1 type 'sbt_tape'
PARMS="SBT_LIBRARY=/usr/local/bin/simpana/Base/libobk.so,BLKSIZE=1048576,ENV=(CV_mmsApiVsn=2,CV_channelPar=ch1,ThreadCommandLine=BACKUP -jm 45 -a 2:71 -cl 9 -ins 9 -at 22 -j 294321 -jt 294321:4:1 -bal 1 -rcp 0 -ms 1 -data -ma 89 -cn oraclehost -vm Instance001)"
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?

Does the full cold backup of rman include online redologs?
So that at the time of recovery when i restore the database the online redologs also restored to that point?

online backup done thru RMAN.Suppose i am taking online backup of full database. During the backup, user's are inserting/deleting/modifying data. This data is getting stored as online archives. Once the database backup is finished, how these archives are applied to the database to make the database up to date.

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 know that the DB INCR is an INCR 0 backup but is there some way query I can join with my example above to tell me this is INCR 0 or FULL BKUP?
I was thinking maybe setting "COMMAND_ID" some text like INCR 0 or INCR 1 or FULL BKUP. Does that sound feasible

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 having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.

I need to restore entire database(sp+control+datafile) to new host.I have started the instance with nomount( and it has created a dummy parameter file).Now, I need to fire the command to restore spfile.
RUN
{
ALLOCATE CHANNEL c1 DEVICE TYPE sbt PARMS='...';
RESTORE SPFILE TO PFILE '?/oradata/test/inittrgta.ora' FROM AUTOBACKUP;
SHUTDOWN ABORT;
}
My questions:-
1.How will RMAN find the location of backupset(Since there is controlfile for neither target or catalog database)?
2.How does RMAN reache the backupset in case of a)tape b)disk?

I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)

I ran the Full database backup as,
RUN {ALLOCATE CHANNEL CH0 TYPE 'sbt_tape';
BACKUP DATABASE FORCE PLUS ARCHIVELOG FORCE NOT BACKED UP DELETE INPUT;
RELEASE CHANNEL CH0;
}
Then I ran the restore, it failed with Quote:RMAN-06054: media recovery requesting unknown archived log....
When I backup archivelogs and choose to delete the input, it does not delete the multiplexed copy, but the specific file being backed up.So, ideally it should find it in Flah Area or at least in the backed up pieces which are there with it.Still why is it failing?
Also, in recovery, it is deleting the archived log after applying, RMAN does this if we use recover... delete archivelog command.I am using only RECOVER, still in output I can see RMAN deleting the log after it has applied it. WHY?

I need to restore a backup of database A from into Database B. Both have the same names. Database B is already up and running.
I have a full rman backup of Database A ( it was taken with a recovery catalog which I don't have access to now as it was deleted ). I just have the full backup pieces including the control files. Is it possible to recover this database into Database B from this stand point.
I was thinking
2. Shutdown database B
3. Mount database B. It has same name as Database A.
4. With RMAN restore controlfile. Will a new controlfile be created from the backup directory I have the rman pieces for the full backup in ?

I have a database for which I use RMAN for backup & recovery. The database is in archivelog mode. Online redo log files are multiplexed and I have more than one destinations for archive logs. If, due to a disk crash, all data files and redo log files are gone - and I have archive logs, one member of each redo log group and a full database backup available, I can recover till the last archived log. But I want to ask that what about the transactions which were not archived at the time of media failure? How can I recover committed transactions which were not archived at the time of crash, and I have a mirrored copy of log group which was current at the time of failure?
