I have oracle ASM instance with 20 TB.
the database mode is NOARCHIVE MODE.
I use also many partition table, one table can have many partition in differents tablespace so i can't use transport tablespace.

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.

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'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)?

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 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?
View 7 Replies View RelatedI 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 ?
crosscheck backup of database vs crosscheck backup command
RMAN> crosscheck backup;
it shows all backup pieces.
RMAN> crosscheck backup of database;
it shows 2 backup piece of each backupset.
when should be use: crosscheck backup of database;
and when should be use: crosscheck backup;
I tried to clone a 2 node rac database to single instance non rac database using existing backup. I have not used connectivity to target or catalog. rman duplicate finished with below messages:

Finished recover at 25-JUL-12
Segmentation fault
And the database was in mount stage, and when i tried to open database it failed with below error:
SQL> alter database open;

ERROR at line 1:

How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.

In the cold backup after database recovery(lost database or control file) we open database in reset logs.Then must and should take the backup of database. Because it will be generates the new redo logs and new SCN numbers.And updates the data file headers and current control file.
At same manor hot backup after database recovery we open database in reset logs. Then it take the backup of database.Is it mandatory? or necessary?
We are having 5 schemas in one database. Now we need to move Oracle server from one machine to another. I can take schema level back up using Export and Import in new server. I am not a DBA as we don't have a DBA I need to do this myself.
I want to know Is there an option to take full database back up including tablespaces and all the schemas in one shot. I read that RMAN is one option. But any option using EXP/IMP for same?
My plan is
-Take list of Tablespaces and create them in new server
-Take Exports of schemas from original server
-Create schemas and import the data in new server.
how can i take backup my all data from database with large object library (blob)
when i want back up i writing this statement on "cmd"

so it's only just backup data without large object library, any table contain large object library it can't take it
so i would like take backup all data from database

I have an oracle 8i recovery scenario. I have database cold backups of MONDAY and WEDNESDAY evenings. backup contains control files, data files, redo files
Database runs in Archive log mode and all archives of the month are available. Hard disk crashed on SATURDAY
all archive logs are still available at different location. Control files are not backed up to trace or file name or automatically means no backup control file (except ones in cold backups described above)
restoring all files from cold backup of either MONDAY or WEDNESDAY (I recovered to Wednesday) leaves nothing to recover. Querying V$RECOVER_FILE returns nothing. All log sequences higher to the number nnn displayed as result of ARCHIVE LOG LIST are present at correct location in correct format
My question is how do i ROLL Forward the Database from WEDNESDAY to SATURDAY in the above scenario.
