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.
ALTER DATABASE DATAFILE '<full_path_file_name>' OFFLINE DROP;
ALTER DATABASE OPEN;
DROP TABLESPACE <tablespace_name> INCLUDING CONTENTS;
CREATE TABLESPACE <tablespace_name> DATAFILE
'<datafile_full_path_name'> SIZE <required_size>;
impdp .....

Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function.

Lost a datafile

Hi all
Here's the scenario:
1. Dont have a backup
2. Lost one datafile in tablespace X
3. Left with only two datafiles in tablespace X
Question:
Is there a way to recover your database in such a way that you don't lose data in the other two remaining datafiles?
Thanks in advance
Durbanite

Well maybe not look for a new job but this problem definitely tells you a great deal of things.
1. You really need to understand Backup and Recovery Concepts and look there are Oracle manuals that can help:
http://www.oracle.com/pls/db102/portal.portal_db?selected=3
Check the ones out that say Backup and Recovery.
2. You really need create a Backup and Recovery Plan.
Look I created a template the could help you it is posted on www.dba-village.com
http://www.dba-village.com/village/dvp_papers.PaperDetails?PaperIdA=3183&SkipA=0&SortA=Date
3. You really need to TEST your Backup and Recovery Plan
Appendix B to your Backup and Recovery Plan from the above step.
4. And at this point I would probably call Oracle or at least submit a TAR or whatever they are calling them nowdays. They can offically confirm the possibility of recovering the database and give offical future guidance.

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:

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

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

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

Restore the dropped tablespace using RMAN?

Hello,
I have done a oracle tablespace re-org for PSAPPOOLD,PSAPPOOLI. Now I want to restore only the OLD PSAPPOOLD,PSAPPOOLI tablespace using TAPE backup via RMAN.
The probelm is I have dropped the old tablespace during re-org which is a part of the re-org. Is it possible to restore the dropped tablespace using RMAN?
My Oracle version is 9.2.05
if anyone has done this before, please share your valuable ideas.
I wrote the below script for the restore.
run {
allocate channel ch1 type sbt_tape;
startup nomount
restore controlfile; -
>(I guess,if I restore old control file, I might get old structure which help the restore of TB)
alter database mount ;
restore tablespace PSAPPOOLD,PSAPPOOLI;
recover tablespace PSAPPOOLD,PSAPPOOLI;;
release channel ch1;
Thanks,
Arjun

Hello Arjun,
why would you want to do this?
What is is you want to achieve by this action?
BTW: it's not possible to do that.
Check [Performing RMAN Tablespace Point-in-Time Recovery|http://download.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmtspit.htm].
You want a "Tablespace point in time recovery" (TSPITR) for a dropped tablespace and that is just not possible with RMAN.
So, the easiest way for you to get this tablespace back would be to restore and recover the database to a different host.
Ah, while we're at it: using RMAN outside the BRTOOLS is not supported by SAP - so you better be a wiz with it because there won't be much help in case anything does not work.
regards,
Lars

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.

Version:-
SQL> select * from v$version;

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.
