Backup your entire database, without archived logs, while the database is open for user activity. This backup should be the base for an incremental backup strategy
View 1 Replies View RelatedI'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)?
View 2 Replies View RelatedAssuming you have a 9i database . where you have it enabled in archive mode , yet constantly deleting the archived redo logs , due to space constraints .
Will you be able to perform a full level 0 backup , and the following incremental backups , in the absence of the archived redo logs ? And are these incremental backups enough to recover the database or particular data files , to the point of the backup itself at least ?
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?
URL....I'm practicing for the OCP test and one of the questions is that there is a backup from yesterday and the last archived logs are from the day before yesterday not mentioned if it's cold or hot backup.
If its a cold backup - cant we recover it? is it a must to have the archived redo logs also when recovering a cold backup? That sounds not logical since those logs are made only for a hot backup. URL.....
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';

I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?
We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.

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

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.

We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process?

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.

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 ?
