The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
i have a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces
I found some of the tablesapces whose used% exceeded 80%.Based on this output i thought of increasing the datafile.But there are many tablespaces of DATA1 whose autoextensible column some are set to NO, and some are set to YES. I believe we dont need to bother about the tablespace whose Autoextensible column set to YES as Oracle will automatically manage until the Maxsize of it. But some tablesapce of DATA1 are set to NO. Should i recommend to add size for this DATA1 tablespace whose autoextensible are set to YES/NO or leave it as it is.
Please see the column below.

I've ran: DROP TABLESPACE x_tbs INCLUDING CONTENTS;
I've read(should have read it prior to action) [URL]tm
and I understand now that I should have stated "AND DATAFILES", However, too late now. the tablespace is removed, but the datafile x_tbs is still present in a folder of my OS.
Is it safe to manually remove it by deleting it from the operating system?
I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?
Erroneously created datafile, re: "/path/../large_rbs_03.dbf" was created under the SYSTEM tablespace which is supposedly be in the LARGE_RBS tablespace.
How do I make the said datafile be under LARGE_RBS?
I need to resize my datafile as i have allocated more space and need to reduce ( i.e.data load completed now). my tablespace is having 11.74 gb free space now. it has 3 datafile.

in TOAD, we have an option, that is "Minimum size" button against each datafile.. Need the SQL which is running behind when we press this button from TOAD ?
Datafile name is +DISK_GROUP_1/oratst1/datafile/system.1122.764387443
displayed for the SYSTEM tablespace in dba_data_files.Infact, datafile name starts with +DISK_GROUP_1 for tablesspaces. Where is the reference to +DISK_GROUP_1.
What file name should I use to resize or to add new datafile to a tablespace?
This facility has one last 10g database and a very problematic tablespace and last datafile associated with it. The tablespace was set up with INITIAL_ EXTENT of 131,072 (128K) instead of the more 'normal' 4,194,304 (4M) and NEXT_EXTENT of 262,144 (256K) instead of 4,194,304 (4M).
More worryingly, the datafile has INCREMENT_BY set to 1 (8K) instead of 1,280 (10M) or 2,048 (16M).Has anyone ever updated sys.ts$.dflinit and sys.ts$. dflincr to modify the INITIAL_EXTENT and NEXT_EXTENT, and sys.file$.inc to modify the INCREMENT_BY?
In my database ,the size of the system tablespace is 1024M.now i found its free space is 477.875M.
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 M FROM DBA_FREE_SPACE where tablespace_name = 'SYSTEM' GROUP BY TABLESPACE_NAME ; TABLESPACE_NAME M --------------- ------- SYSTEM 477.875
In system tablespace ,the max size segment is IDL_UB1$,it is 167M
SQL> SELECT SEGMENT_NAME, SX || 'M' "Size" FROM (SELECT SEGMENT_NAME,SUM(BYTES)/1024/1024 SX FROM DBA_SEGMENTS WHERE TABLESPACE_NAME = 'SYSTEM' GROUP BY SEGMENT_NAME) WHERE SX > 100 ORDER BY SX DESC; SEGMENT_NAME Size ------------- ----- IDL_UB1$ 167M
My system tablespace size is 800mb and it sends an alert saying that it has exceeded 80% of its usage.However its total max size is 30gb.
FYI Its autoextensible is set to 'YES'. 2 Node RAC database. File system is ASM
My question here is... is it advicable to resize a system tablespace to some size when autoextensible is set to 'YES' or genrally can we resize a system tablespace when autoextensible is set to 'No' ?
SQL> col FILE_NAME format a40 SQL> / FILE_NAME BYTES/1024/1024 AUT MAXBYTES/1024/1024 ---------------------------------------- --------------- --- ------------------ +DATA/ge01114/datafile/system.556.2254454 800 YES 30000.9844
The SYSTEM tablespace refuses to autoextend (3 segments in SYSTEM tablespace unable to extend). It sits on its current size of 559MB (auto set to 2GB, increment 10M).
I guess there are no free extends that are that big as 10M.
As the undo segments are used in round robin fashion, Is it possible that with varying load (concurrent users, size and number of transactions), the size of Undo tablespace on a particular day is less than the Undo tablespace size few days back, by any chance?
As a basic understanding I know that Undo is preserved for read consistency and transaction, instance recovery So if there are lot of transaction on a database on 05 Feb and before that, but there aren't any transactions on 6,7,8,9, then on 10th Feb can we see the Undo tablespace size is less than that of 05 Feb?
In the following case when data belonging to table is not required for any queries, transactions, even then the undo size is not restored upon dropping the table.
As such for large operations and batch processes shall we keep undo tablespace with files as 'Autoextend' with 'Maxsize' as 'Unlimited'?
I want to increase the size of the tablespace but when i login as sysdba or admin user i can just see the 21 tables in the dba_tablespaces or user_tablespaces. I want to see the tablespaces related to the application.
we have a tablespace of size 900 GB where 90% of space is occupied by two tables having BLOB data and now i need to drop these two tables and then to recover the space, i need to resize the tablespace (datafiles).
I want to OFF tablspace AUTOEXTEND on a prodution system, we have many RAC databses and that will be done on all stations. i have got a document from net which was written on 29-Jun-2007 and it says that if need to OFF the AUTOEXTEND of a TABLESPACE so you need to ist make it off on the underlying datafiles of that tablespace so this doc is for Oracle 8.1.7.2.0
i want to create tablespace in raw partion on windows.I have added a hard disk and added extended partition to it. Then created 4 logical partitions of 256 MB with diskpart.exe.I have assigned a drive letter to one of them as X:
However, I am having trouble in creating tablespace on it. I referred to [URL]... I get following error,

Here is my problem : I create a tablespace named ts_photos.I create then a table on this tablespace.Then I insert some blobs records.The space grows up to 2 Gb.
I perform a truncate statment. Then the space grows up to 4Gb.I re-insert the same records and the size stays in 4Gb.The database in in archivelog mode. How can I return to the initial size (2Gb of effective data) : should I drop the tablespace and recreate it?
i written this code i m facing ORA-04030: out of process memory when trying to allocate 16408 bytes error

what are the minimum files which are required to open the db ? take it as this
I have oracle installed in c drive. I have placed 3 datafile related to one tablespace say test: two in D and one in E. I have place 3 datafile related to tablespace say orcl : two in D and one in E.
my undo is in E scenario is that my E drive crashed . db is in no archive mode . no backup is there. to be more worst db shuts down abnormally. I want my db open with data of c drive and D drive.
i have exp dump of size 1gb but when i tried to imp ,it showing error of space , it asking for space of 4gb. But i have 1gb on c: drive and 32gb on d: ,can i add datafile on d: locaion and what is max size i can assign to that datafile .
