Backup of one tablespace in noarchivelog mode

Hi,
I am running 10g.
Is it possibe to backup a specific tablespace in noarchive mode?
Thanks

Hi
I am able to backup the tablespace,
but after the recovery loosing the table data.
The database is in noarchivelog mode!
here is what I am doing:
my_table TABLE has 100 rows, and is saved under my_tablespace TABLESPACE.
RMAN> sql 'alter tablespace my_tablespace offline';
RMAN> backup tablespace my_tablespace;
RMAN> sql 'alter tablespace my_tablespace online';
Now I truncate the table
TRUNCATE TABLE my_table;
RMAN> sql 'alter tablespace my_tablespace offline';
RMAN> restore tablespace my_tablespace;
RMAN> recover tablespace my_tablespace;
RMAN> sql 'alter tablespace my_tablespace online';
Now the my_table TABLE is after the rcovery empty :-(

Reagrds,

We have to restore all 50 GB database if we fail in scripts meanwhile to start again the data load.
Out scripts populater only two tablespaces.
That's why if i take backup of those tabblespace then i have to restore only those tablespace not whole database.

RMAN level 0 backup with bigfile tablespaces

We noticed that our rman backup process for PROD database is not working properly.
PROD is a 8 TB size database having two bigfile tablespaces each having more than 2 TB datafile.
PROD is a 11gR1 (11.1.0.7) RAC database with ASM storage.
We are taking weekly incremental level 0 backup for entire database and level 1 backup every day.
As per v$session_longops, the approx completion time for the two tablespaces is 5 days.
We can use "SECTION SIZE" parameter to take rman backup for bigfile tablespaces and exclude them from the level 0 backup.
However, in this case our level 0 backup wont include the two bigfile tablespaces and the daily level 1 backup will not include them.
Will you pls advise us on how to take backup in this scenario.
we have only 4TB of LUN allocated for backup and have to keep 7 days of backup on disk.
Thanks in advance !
DR

We can use "SECTION SIZE" parameter to take rman backup for bigfile tablespaces and exclude them from the level 0 backup.
How do you think that the backup will be useful if you exclude some files from level 0 or base backup? You will find difficulties or you can't restore the database in case of disaster.
Yes you can use section size parameter for paralleled big file tablespace backup.
Check below for explanation and example.

I do not think you can find a script that list all the tablespaces/table and what processes are filling them. You can query dba_segments to determine the tables size and then you can start troubleshooting.

How to backup read only tablespace in rman

Hi,
I am using oracle 10gR2 in solaris 10.
I am taking Rman full backup using catalog.
My target database have 5 datafiles, in that one datafile is in read only mode.
When I issue the backup command in rman. it takes only 4 datafiles. its not taking the readonly datafile.
I want to take backup of all 5 datafiles.
kindly help me..
Many Thanks

My target database have 5 datafiles, in that one datafile is in read only mode.I presume that you mean to say that 1 Tablespace consisting of 1 datafile is Read Only.
What does SHOW ALL in RMAN present ?
If you have BACKUP OPTIMIZATION set to ON, the Read Only Tablespace will not be backed up after the first backup.
You could still explicitly backup the tablespace with a BACKUP TABLESPACE tablespacename; , although a BACKUP DATABASE would exclude it.

RMAN Backup specially for tablespaces

Hi@everybody,
we have a Oracle 11gR2 (11.2.0.3.0) Server, based on RedHat 6, running in our company. For the Backups i'm using RMAN with a script. In that script this code specially creates the backup:
        run {
            allocate channel oem_backup_disk1 type disk;
            backup incremental level ${level} cumulative as COMPRESSED BACKUPSET tag '${tag}' database;
            backup as COMPRESSED BACKUPSET tag '${tag}' archivelog all not backed up;
            release channel oem_backup_disk1;
${level} is for 0 or 1, full backup or incremental backup. ${tag} is the name for the backup. This script is for the hole database. But now i want to change that script to tablespace level. We have some "test" tablespaces, where a backup is not needed. I just found that one:
backup tablespace TEST tag='BACKUP_TEST';
But now i'm not shure how i can implement that into my script.
Can you guys help me?
Thanks and best regards,
David

I've just to ask again to understand it right:
In RMAN - Console i just exclude the tablespaces that should not be backed up with:
CONFIGURE EXCLUDE FOR TABLESPACE Tbs1, tbs2, tbs5;
And then RMAN knows, when he is doing a backup of the database, he will exclude that tablespaces that i've told him? Thats awesome! And easier to handle!
EDIT: I've tested this on my Oracle Test server and it works! Thanks a lot for the answers!

Backup and recovery tablespace.

Hi all,
one is production server and second one is totally fresh server. I had created database manually.
We are migrating the database from hpux to hpux but from one server which is in boston and second server is on chicago.
which is the fast way to do it.
is there any good documents which i can refer?.
thanks a lot.

Logical steps for database backup and recover.
1)     Take RMAN full backup of the 5 customer tablespaces being migrated from
H1 to the mounted Data Domain Server
Read the script for convert tablespace. :Convert data files for non asm server.
2)     Restore table space to the tower hpux server for the new database.
3)     Take an incremental backup from HPUX Burlington. Then repeat step 2nd again for the restore tablespace.
Physical steps for database backup and recover.
1)     This will take a Full backup of table space automatic.      TABLESPACE BACKUP=
RMAN> run {allocate channel d1 type disk;
     backup
     tag tbs_users_read_only
     convert tablespace (table space_name) format '(location for backup tablespace
/backups/ (NEW NAME)tbs_2_%U.dbf '
     (tablespace users)(TABLESPACE SYSTEM)(REST);
     release channel d1; }
2) At HTTOWER database make a table space offline and restore and recover the system.
sql ‘alter tablespace tablespace_name offline;
restore tablespace tablespace_name;
recover tablespace tablespace_name; (change no);
sql ‘alter tablespace tablespace_name online;
3) Take a Incremental level table space backup from burlington.
BACKUP INCREMENTAL LEVEL 1
     TABLESPACE (tablespace_name)
     DATAFILE 'ora_home/oradata/trgt/tools01.dbf';
(For all the data files.)
4) At HTTOWER database make a table space offline and
restore and recover the system.
sql ‘alter tablespace tablespace_name offline;
restore tablespace tablespace_name;
     recover tablespace tablespace_name;
sql ‘alter tablespace tablespace_name online;
something like this..

Backup a user/tablespace with trigger

Hi,
i have an database from which i have to backup the data user by user (or if there is no way tablespace by tablespace) and every user at another time. And now i need a solution how to backup the user (maybe the tablepace) an all his trigger and so on. But i don´t want to backup the sys every time.
Is there any possibility to do this?

If you want to store all data of a specific user you still have to use export (or datapump in 10g). Although it is possible to backup single tablespaces, it wouldn't help you, trigger definitions are stored in the data dictionary, that means in the SYSTEM tablespace.
Export is not a compensation for a regular backup, when data changes after the export was taken this data is lost.

User specific previledges on a particular tablespace

Hi,
1. I have created a user giving him permission for a
default tablespace for him.Can i revoke his
permissions from all other available tablespaces . If
yes? How?
2. I have gone through some related documents that says
we can change user's tablespace quota to zero.Can we
make it zero for all other tablespaces except his
default tablespace.If yes ? How?

As long as the user does not have resourse role, or DBA role, then he, by default, has no quota on any tablespaces... even his default one. So, you allot quota per tablespace to the user.
ALTER USER SCOTT
QUOTA UNLIMITED ON EXAMPLE_TS
"UNLIMITED" could be "5M" or whatever you want it to be. To remove this quota, make that be "0K". That's a zero followed by a K - not the work "okay". OK?

Single Tablespace Backup, Restore and Recovery

Hi Experts,
I need your kind help. Actually I want to take hot backup by RMAN for a particular TABLESPACE ..
I know this is possible. My question is when I restore a tablespace to any other test database
I need to create new database or I can restore it to any existing database? Just like adding new tablespace??
To recover this tablespace I need to archive log backup ?
How I can open the database on which I m going to restore/recover this particular tablespace ???
Regards,
Rizwan

You cannot copy a tablespace from one database to another using the normal Backup/Restore methods.
You have to use the TTS (Transportable Tablespace) methods.

Restoring a Rman Tablespace backup to noarchilog mode database

Hi All,
Is it possible to take a backup of a tablespace through rman from archivelog mode database and restore the same to noarchivelog mode database through rman ? Please suggest if it is not possible why it is not possible.
We have a testing database from which a tablespace has been dropped. Can it be restored from the Prod database ?
Please help. The database version is 9.2.0.8..

Being able to backup a single tablespace is NOT the same as grafting that TS into a different database.
First, you are not really backing up a 'tablespace'. You are backing up files. In this case, just the files that implement the named TS, but files, nevertheless. And files belong to a database. Header info in each file defines, among other things, the dbid of the database the file belongs to. And the current scn. That will be a severe mis-match if you tried to 'restore' it to some other db.
