Droping a datafile from a tablespace

I want to drop a datafile from a tablespace by using the query
SQL> alter tablespace TS1 drop datafile 'OS path\df1';
This query drops the datafile. But physically the datafile is present in the OS path. how to delete the datafile completely from the disk.

DROP DATAFILE FROM A TABLESPACE

What is the difference between "ALTER TABLESPACE DROP DATAFILE ..." and "ALTER DATABASE DATAFILE ... OFFLINE DROP"?
I read the Oracle document before, it tolds me that the "ALTER DATABASE DATAFILE ... OFFLINE DROP" is not really drop data file. But, does the "ALTER TABLESPACE DROP DATAFILE ..." really drop data file?

"ALTER DATABASE DATAFILE ... OFFLINE DROP"
will take datafile offline to drop it later. In this case your control file will need to be recreated to de-link the datafile from database.
From 10g onwards you can ALTER TABLESPACE DROP DATAFILE... but in this case datafile should not contain any data in it.

Missing datafile from system-tablespace?

Hello!
We've got a major power-loss yesterday. After that our database does not start correct.
I got the message:
ORA-00600: Interner Fehlercode, Argumente: [kccpb_sanity_check_2], [9577], [9542], [0x0], [], [], [], []
After that I searched the forum and recreated the controlfiles and started recover database.
Now I always got the following error-message:
ORA-01173:Data dictionary indicates missing data file from system tablespace
I'm not really shure if I created another datafile for that tablespace. Even though there is no other datafile in the "oradata-directory".
Does anyone know how to go further?

Remove datafile from database

Hello all,
I have a database 11.1.0.7 where I wanted to remove a datafile. The database is in archivelog.
The first thing that I did was to make sure that no data was in the datafile. - OK
Then, since I only wanted to remove 1 week later, I put the datafile offline - OK
On the day (one week after putting it offline) that I was going to remove/drop the datafile from the tablespace I got an ORA- saying to put the datafile online before dropping.
And here is my problem! The database says that the datafile needs recover :(
Questions:
1- If the datafile was offline, why does it need recover?
2- Do you thing that the database will ask for all archivelogs until now to recover this datafile ?
3- If I dont want to apply all archivelogs, can I simply remove the datafile by recreating the controlfile without this datafile?
Thank you.

Questions:
1- If the datafile was offline, why does it need recover?The SCN must be alligned with the DB
2- Do you thing that the database will ask for all archivelogs until now to recover this datafile ?I never tried that with missing archived logs so I cannot say it. Just try and you will see.
3- If I dont want to apply all archivelogs, can I simply remove the datafile by recreating the controlfile without this datafile?The problem is that this datafile is registered in the dictionary. You cannot do it.
Probably you got this exception:
ORA-03264: cannot drop offline datafile of locally managed tablespace
Cause: Trying to drop offline datafile in lmts
Action: Try to drop file after making it onlinehttp://download.oracle.com/docs/cd/B28359_01/server.111/b28310/dfiles006.htm#ADMIN11435
Restrictions for Dropping Datafiles
The following are restrictions for dropping datafiles and tempfiles:
- The database must be open.
- If a datafile is not empty, it cannot be dropped.
- If you must remove a datafile that is not empty and that cannot be made empty by dropping schema objects, you must drop the tablespace that contains the datafile.
- You cannot drop the first or only datafile in a tablespace.
- This means that DROP DATAFILE cannot be used with a bigfile tablespace.
- You cannot drop datafiles in a read-only tablespace.
- You cannot drop datafiles in the SYSTEM tablespace.
- If a datafile in a locally managed tablespace is offline, it cannot be dropped.

Drop datafile from a offline tablespace

We are running oracle 9.2 on windows.
Out of the 3 datafiles in a non-system tablespace A, one datafile A-DF1 was accidently droped from the file system by our DBA.
The other two datafiles were brought online by using the ALTER DATABASE RECOVER command by bringning the database in mount phase.
Now we want to remove that datafile A-DF1 from the tablespace and bring that tablespace online.
The database is not in archive mode and no cold backup was present.
The solution that we want to try is:
1-drop the tablespace A without dropping the datafiles
2-create a new tablespace and reuse those datafiles
3-assign this new tablespace to the affected user
Would this work? Do you have any other safe solution for this problem?
thanks
Imran

Hi..
Your solution is a wrong solution.
1. I guess, that the tablespace A won't be a empty tablespace.As, the objects are present in the tablespace you can't drop the tablespace without dropping its contents.You will have to use *DROP TABLESPACE <tbs_name> INCLUDING CONTENTS; -- This will drop all the contents.
2. Do, you have a export backup, or any kind of backup.As the database is in no archivelog mode, you won't be able to do complete recovery.
3. Take the datafile A-DF1 OFFLINE and keep the tablespace online. -- alter database datafile 'datafile_name' offline;
If you don't have any kind of backup, the data is LOST.

Need to drop datafile from my undo tablespace

I have a undo tablespace and it has 2 datafiles. i would like to drop one datafile.
befor i am droping this datafile i am going to bring this file to offline and i got this message: ORA--01145 offline immediate disallowed unless media recovery enable.
can someone tell me how i can safly do it without any problem.
Thanks

An undo tablespace can be dropped like any other tablespace, but not until all transactions within the tablespace are complete. First, specify a new undo tablespace as in the previous example. To see if the tablespace has any pending transactions, run the following query:
SQL> select rn.name, rs.status
2 from v$rollname rn, v$rollstat rs
3 where rn.name in
4 (select segment_name from dba_segments
5 where tablespace_name = 'UNDOTBS')
6 and rn.usn = rs.usn
7 ;

8.3.4 Renaming a Datafile in the Primary Database
When you rename one or more datafiles in the primary database, the change is not propagated to the standby database. Therefore, if you want to rename the same datafiles on the standby database, you must manually make the equivalent modifications on the standby database because the modifications are not performed automatically, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.
The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.
   1.
      To rename the datafile in the primary database, take the tablespace offline:
      SQL> ALTER TABLESPACE tbs_4 OFFLINE;
   2.
      Exit from the SQL prompt and issue an operating system command, such as the following UNIX mv command, to rename the datafile on the primary system:
      % mv /disk1/oracle/oradata/payroll/tbs_4.dbf
      /disk1/oracle/oradata/payroll/tbs_x.dbf
   3.
      Rename the datafile in the primary database and bring the tablespace back online:
      SQL> ALTER TABLESPACE tbs_4 RENAME DATAFILE      2> '/disk1/oracle/oradata/payroll/tbs_4.dbf'
        3> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
      SQL> ALTER TABLESPACE tbs_4 ONLINE;
   4.
      Connect to the standby database, query the V$ARCHIVED_LOG view to verify all of the archived redo log files are applied, and then stop Redo Apply:
      SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
      SEQUENCE# APP
      8 YES
      9 YES
      10 YES
      11 YES
      4 rows selected.
      SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
   5.
      Shut down the standby database:
      SQL> SHUTDOWN;
   6.
      Rename the datafile at the standby site using an operating system command, such as the UNIX mv command:
      % mv /disk1/oracle/oradata/payroll/tbs_4.dbf /disk1/oracle/oradata/payroll/tbs_x.dbf
   7.
      Start and mount the standby database:
      SQL> STARTUP MOUNT;
   8.
      Rename the datafile in the standby control file. Note that the STANDBY_FILE_MANAGEMENT initialization parameter must be set to MANUAL.
      SQL> ALTER DATABASE RENAME FILE '/disk1/oracle/oradata/payroll/tbs_4.dbf'
        2> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
   9.
      On the standby database, restart Redo Apply:
      SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
        2> DISCONNECT FROM SESSION;
If you do not rename the corresponding datafile at the standby system, and then try to refresh the standby database control file, the standby database will attempt to use the renamed datafile, but it will not find it. Consequently, you will see error messages similar to the following in the alert log:
ORA-00283: recovery session canceled due to errors
ORA-01157: cannot identify/lock datafile 4 - see DBWR trace file
ORA-01110: datafile 4: '/Disk1/oracle/oradata/payroll/tbs_x.dbf'Hope That Helps.

Drop one datafile from Tablespace

Hi,
I have 9i Database on Linux. I want to drop one datafile from tablespace. I have tried to drop datafile through following command but it gave no effect.
alter database datafile <datafile name> offline drop;
What should i have to do for dropping datafile?
Do the needful
Thankx in advance.

Hi
since you dont specify the database version or if you have it setup as archivelog or noarchivelog mode, i paste the drop specs for dropping a datafile, from SQL Reference manual of 9i
DROP If the database is in NOARCHIVELOG mode, you must specify the DROP
clause to take a datafile offline. However, the DROP clause does not remove the
datafile from the database. To do that, you must drop the tablespace in which the
datafile resides. Until you do so, the datafile remains in the data dictionary with the
status RECOVER or OFFLINE.
If the database is in ARCHIVELOG mode, Oracle ignores the DROP keyword.

Drop datafile from tablespace

I'm new to oracle.
After I extended a tablespace I understood that it was too large.
I've been reading about how to drop a tablespace, but I don't want to drop the entire tablespace. I just want to drop the last datafile of this tablespace.
I know how to drop tablespaces in sapdba and brtools, but I don't know how I can drop one specific datafile (number 29) of the tablespace PSAPBTABD?
Please Help med.
Best regards
Harald V

Hello Harald,
see please this thread:
Re: How to drop data file?
also the section 43. How can I delete a data file that was created by mistake
in the SAP Note 592393 - FAQ: Oracle
if you have Oracle 9i databases, it is not easy to drop a datafile, but in Oracle 10g
you can drop a datafile like that:
ALTER TABLESPACE <Tablespace Name> DROP DATAFILE '<PATH und NAME of Datafile>';
for example, you have a tablespace called PSAPC11 and you want to drop a datafile called dat.data15 of this tablespace, you can drop it like that:
e.g. alter tablespace PSAPC11 drop datafile '/oracle/C11/psapc11/dat.data15'

Drop a datafile from physical standby's control file

Hi,
I am trying to create a physical standby database for my production...
1) I have taken cold backup of my primary database on 18-Nov-2013...
2) I added a datafile on 19-nov-2013 ( 'O:\ORADATA\SFMS\SFMS_DATA4.DBF' )
3) Standby control file was generated on 20-ov-2013 (today) after shutting down and then mounting the primary database...
When i try to recover the newly setup standby using archive files, i am getting the following error (datafile added on 19th Nov is missing)

Hi,
What is your version?
If you added new datafile or created new tablespace, take backup again for restore new created standby database.
If your standby database running well, DG configuration success, then this datafile will create on standby side, too.
Set STANDBY_FILE_MANAGEMENT=AUTO best practice.

Not need any delete datafile from standby side, you must recreate standby database, or you can take RMAN backup and restore to standby side again.

It is not logical, Physical standby must be bit-for-bit same with Primary database.

How to drop the datafile in a tablespace

hi,
I need to drop the datafile in a tablespace.How to drop the datafile in the tablespace.If iam able to drop the datafile and is it possible to create the datafiles with the same name.could u pls help me out..
Thanks in advance,
R.Ratheesh

sql > alter database <datafile> offline drop ;
sql > alter database open ;What if the datafile have the segments in it, I believe users will not be able to access them. And system will put the datafile to Recovry mode not drop it.
Dropping a datafle is possible only in 10G. In 9i you can reduce the size of file below the size of your min extents so that the space wont be allocated from that datafile or you may need to recreate a new tablespace copy all the segments from old tablespace and drop old one.
Cheers

Recovering a datafile from backup in different server

Hi All,
I usually take hot backup of datafiles to different server like this because i dont have enough space in same server. I
SQL> alter tablespace XXXX begin backup;
host scp /bu1/oradaTA/XXXXX/XXXXX [email protected]:/db1dw/oradata/backup/dec2010/XXXX
alter tablespace OPS end backup;
If i want to recover the datafile can i normally do the offline drop of that datafile and copy the datafile from backup which is in differnet server thorugh scp and make the datafile online??? and the database is in archivelog mode but i dont care abt the log files. i just need to recover the datafile as it was from last backup.
or do we need to use any recover datafile commands?? if need to use any recover datafile command from where it will recover the datafile??
i dont have any scripts for backup or recovery , i just take manual scp of the datafiles.
Help plzz, thanks in advance.....

SQL> alter tablespace XXXX begin backup;
host scp /bu1/oradaTA/XXXXX/XXXXX [email protected]:/db1dw/oradata/backup/dec2010/XXXX
alter tablespace OPS end backup;What is the version you are using? is it 9i if not you can peform backup at database level instead of tablespace level.
If i want to recover the datafile can i normally do the offline drop of that datafile and copy the datafile from backup which is in differnet server thorugh scp and make the datafile online??? and the database is in archivelog mode but i dont care abt the log files. i just need to recover the datafile as it was from last backup.Why offline drop to recover? Are you sure what are you doing?
or do we need to use any recover datafile commands?? if need to use any recover datafile command from where it will recover the datafile??1) alter system switch logfile;
2) select max(sequence#) from v$archived_log;
For Ex:
Sequence -- 100
3) alter database begin backup;
4) copy all the datafiles to another server(bcoz you not have space in same server)
5) alter database end backup;
6) select max(sequence#) from v$archived_log;
For Ex:
Sequence -- 110
Then copy these generated 10 archives to new server also.

Create database using datafiles from cold backup

hi,
I've been given a bunch of datafiles from a cold backup.
I have created my own database using the same DB_NAME as the original.
I now want to be able to attach these datafiles to my database. How do I go about? Do I need to start the database in mount mode so that the control file is open, then start adding these datafiles to the tablespace, and then open the database?
Any help would be appreciated.
Thank you.

Thank you.Hi,That is not possible.You actually have two different databases,however db_name is same but every db_name are same databases is not same.These has own DBID in same environment.(Their controlfile and datafile information exactly is different).There is similar way is transportable tablespace feature.You can use this feature to transport tablespace between databases.For more information see below link.
