Suppose our database have 100 datafiles and right now rman has completed backup of 64 datafile(from file no 1 to file no 64) and in process of backup of 65 number datafile. In mean time I executed some query and it has changed the file no 55. so now my question whether rman will go and bacup this datafile(datafile no 55) again or it will leave this file as it is?
View 4 RepliesI have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time
it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)
I have no backup taken in my oracle server.Today morning i created a data file and unknowingly deleted it. Now i need to restore the datafile with its contents without using RMAN.
View 14 Replies View RelatedAs part of an incremental backup I recover copies of the tablespaces. These by default are stored in the disk backup location diskgroup. Is it possible to move these copies to another disk group / location whilst still backing up to the default disk backup location diskgroup. I know how to do it with the main datafiles but not with the copies.
e.g.
Current situation:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +FRA
New setup to be:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +BACKUP
how i can change backup datafile name into its original file name,bcoz at time backup datafile name is different and how i can change that name into its original datafile name so i apply recovery command in user managaed recovery..

1) What caused the above missing files to get created?
2) What is recommended: Recover the datafiles?

10.2 Oracle database on Linux
Someone(a non DBA) removed the only sysaux datafile from the server using the rm command Obviously, the DB is still up and none of the schemas in the database have their objects right now.
This is not a critical database as you can see when I say that I have NO backup whatsoever. Even though I have the option of deleting and recreating the database, i want to know if I can avoid doing that.
Creating a file on the server with the same name OR creating a new datafile for the tablespace OR recreate the sysaux tablespace ?But how to do any of these? What else should be done ?

View 24 Replies View RelatedWe 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:

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;

Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?
A.Configure backup optimization
B.Configure the channel to increase MAXOPENFILES
C.Configure the channel to increase the capacity with the RATE parameter
D.Configure the channel to adjust the tape buffer size with the BLKSIZE option
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.
