Adding a datafile to a tablespace?

hi all,
what are the prequisites of adding a datafile to a tablespace
& how is it performed? pls help?
regards,
vivek.

Hi,
prequisites of adding a datafile to a tablespace
1. check for Tablespace Threshold level should be more than 90%(in db02 tcode).
2. There shd be no backup running while adding datafile to Tablespace.
3. check for the size of datafile should be added to Tablespace.
Goto Brtools--->login as sidadm
BR*Tools main menu
1 = Instance management
2 - Space management
3 - Segment management
4 - Backup and database copy
5 - Restore and recovery
6 - Check and verification
7 - Database statistics
8 - Additional functions
9 - Exit program
select option 2 - Space management.> Then select 1 = Extend tablespace> 3 ~ Tablespace name (tablespace) ... []-->
5 - Size of the new file in MB (size) ..... [3500] then continuosly select c-continue
With this steps your datafile will be added to Tablespace.
Thanks,
Ramakrishna.

Query in adding a datafile to the tablespace ?

Hi All,
A small qry? Suppose i am having a datafile .DBF of Size 26 GB , and now i want to add another Datafile to the tablespace. Then how to stop insertion of data into that 26 GB file , while the 2nd Datafile should start accepting the data. Is it an automatic process or we have to issuse some commands ??. Kindly provide some document links.
Regards

Thanks for the reply sir
But if we declare 3 datafiles at the time of DB
Creation then how is three datafiles handled.
Insertion of data is simultaneous in all of the three
files or in a single file?????The Insertion of data in the datafile can't be handled be you. Oracle manages automatically. To elaborate further the freelist in the segments are response the data insertion. Better solution for your scenario is create tablespace with ample no. of datafiles and then export and import utility.
with regards

Lost of datafile to 2 tablespaces, no rman but expdp image

Hello,
We lost 2 datafiles to 2 tablespaces in our non-production database. We can not open the database because of the missing 2 datafiles on the same mountpoint. The database is mounted. How to drop these 2 tablespaces and datafiles so the database can be open? We do not have rman but do have expdp files as backup. Thank you.

Offline drop the datafiles,drop the tablespaces,recreate them,import the data.

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

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?
Regards, Sascha

Adding datafile automatically when tablespace is 90% full

Hi,
I have a tablesspace having a name user01.dbf(Auto extensible to 4 GB) user02.dbf(Auto extensible to 4GB) ..........
I am just thinking about automatically creating datafile(alter tablespace add datafile).
1. (total number of datafiel in tablespace) *4 - space used by dba_segments belonging to user tablespace. if it returns less then 1 GB space, then add a datafile.
And I will put it on CRONTAB. and it will run every 24/7.
Does not this look weired?
Advice:
1. Don't we have any option like the database server will trigger an event when it is 90% and I can trap this event and run a command to add a datafile. I know internally it will do the same but still I feel if you have a feature then why not use it.
Any information will be helpful in this regards. And the same question is for OS level do I have to check it every second, space on the file system?

Do one thing ,write a script which will check free space of your tablespaces like..
SELECT NAME FROM V$DATABASE;
select to_char(sysdate,'dd-MON-yyyy hh:mi:ss')Snap_ShotTime from dual;
SELECT Total.name "Tablespace Name",
nvl(free_space, 0) free_space,
nvl(total_space-free_space, 0) Used_space,
total_space
FROM
(select tablespace_name, sum(bytes/1024/1024) free_Space
from sys.dba_free_space
group by tablespace_name
) free,
(select b.name, sum(bytes/1024/1024) TOTAL_SPACE
from sys.v_$datafile a, sys.v_$tablespace B
where a.ts# = b.ts#
group by b.name
) Total
WHERE free.Tablespace_name(+) = Total.name
AND Tablespace_name <> 'PERFSTAT'
ORDER BY Total.name;
and find the %age of used space Vs free space.Enable your mail server which will send you the alerts.
Put in crotab file and set them accordingly..

There are two possibilities for that error:
- the logged in user has no permissions to create a directory
- brtools were updated and "saproot.sh" did not run to adapt the permissions (s-user-bit) for brspace

TEMP datafiles for temporary tablespaces don't have same timestamp

Hi,
This is what I have done:
Installing 10G2 on XP PRO with sample database.
Tried to install Designer Repository with the Wizard, created a user for the toolkit, that failed.
Added 1 temp tablespace size 20Meg from OEM console.
Dropped cascade Toolkit schema owner and recreated it
Tried to install Designer Repository, that failed again
Added 1 temp tablespace size 1giga from OEM console, failed again to import
Dropped cascade Toolkit schema owner and recreated it
Tried to install Designer Repository, that failed again
Gave up for now: I have located a doc about installing manually by running scripts, will do as soon as I feel at ease with OEM.
Then I put the PC on snooze while database was up, crashed it.
Stopped the services, checked the logs, restarted manually and slowly, base up.
Now both extra TEMP datafiles are lagging behind, seen from Windows explorer, but the tablespaces are seen as online from oem, not seen from sqlplus dba_tablespaces view.
So the question is:
Are the TEMP datafiles supposed to stay in sync with the others or is it ok if they show timestamps dating three days back, provided there has not been any users transactions in the database?
I checked the 10G2 DBA online doc, but I can't find where it's mentioned.
Many thanks if you can help.

Hi,
Everything allright, they do show!
I'm a bit wary about resizing anything, maybe you remember the resizing bug for SYSTEM tablespace in version 7?
I have to beef up on DBA tricks.
Since I also have a 1 Giga Users tablespace, I'll do some heavy Inserting and Updating and Sorting see if that tickles the Temps.
Many thanks for your prompt reply.

How to open database when datafile of nonsystem tablespace is missing?

Hi,
I am runnig 10gR2 on Windows XP SP 2
Here my situation:
My db is running in archive mode. I have taken backup of my tablespace 'ocp' by using RMAN with Database Control.
Now I shutdown the db and removed datafile which belongs to the tablespace.
My problem is now that I am able to start db in mount only.
I can not open it and getting folowing error:
SQL> alter database open;
alter database open
ERROR at line 1:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: 'C:\ORACLE\ORADATA\ORCL\OCP.DBF'
My question is:
How to drop the tablespase and run backup?
Thanks

Hi, you must mount the database and put the datafiles in offline mode
ALTER DATABASE DATAFILE '<full_path_file_name>' OFFLINE DROP
After you must open the database.
Luck.
Have a good day.

How does oracle write to datafiles in a tablespace?

hi all
Suppose I have a tablespace consisting of two datafiles. When I need to wirte data onto it，how does ORACLE
write ? Does it initially write to the first datafile and then write to the second datafile when the first datafile getting full or write to two datafiles in an random manner?
Thanks for your reply.

hi all
I have read reply in reponse to thread "tablespaces or datafile " and testcase in that thread shows that ORACLE will write to datafiles in round-robin manner.
But my test show totally different result:
