Server Administration :: Remove Datafile From Operating System After Dropping Its Tablespace
Jul 26, 2012
I want to remove a tablespace with it's datafile.
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?

what is the Minimum datafile size required for creating a non-system tablespace?
I am trying to create a tablespace by giving the syntax like,
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;
Tablespace created.
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.

We are in the process of gaining some space in our database. We identified a tablespace that occupied around 400GB of space. The datas are required for us. Hence, we truncated (with drop storage) the tables, gathered statistics and shrinked the tables. After doing that we found the datafile occupied around 32GB of space. We tried to resize it to 5 GB and we got "ORA-03297: file contains used data beyond requested RESIZE value". We could see that size in dba_free_space against that tablespace. We would like to give back everything to OS.
We also tried exporting the tablespace without rows, dropped the tablespace and re-created and imported again. But the datafile grows to around 32G and we are unable to resize it.
We are sure that the tablespace has only the table definitions without data. But we do not know why is it occupying around 32G of space and we could see that size in dba_free_space. We would like to give back everything to OS. How can we do that?

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?

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
QUESTION: what's the table IDL_UB1$ used for ?

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' ?

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.

is it possible to get information about free space on drive/path for example with some DBMS_*, UTL_* package or with stored function based on Java
(e.g. CREATE OR REPLACE FUNCTION GetFreeSpace(driveLetter IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'DiskSpace.getFreeBytes(java.lang.String) return java.lang.String') but for JDK 1.3

I"Host operating system was experiencing significant paging but no particular root cause could be detected. Investigate processes that do not belong to this instance running on the host that are consuming significant amount of virtual memory. Also consider adding more physical memory to the host."
My database run on Windows Server 2008 R2 and have 12GB of physical RAM.
Oracle version is 10.2.0.4.0 and my sga and pga are:
sga_max_size 4000M
sga_target 3904M
pga 1200M
I try to find out something about this issue and read many blogs but unfortunately I didnt find anything which worked. Should this have something to do with the fact that on the server we have oracle database and terminal server with 30-40 users?

I was setting up disks groups and I accidentally created one group (DATA) with "NORMAL" redundancy but wanted it to be "EXTERNAL". I tried using asmca to remove disks from the group, drop the group, change the redundancy..... All of this failed because there was an spfile on the disk group.
I finally got it to work with using this procedure:
sqlplus '/ as sysasm'
SQL*Plus: Release 11.2.0.3.0 Production on Thu Apr 5 08:58:19 2012

SQL> drop diskgroup DATA;
drop diskgroup DATA
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15053: diskgroup "DATA" contains existing files
[code]....
In summary, I am not sure why changing the redundancy would be so difficult if there is data on the disk group.

I created an encrypted tablespace for testing. I later dropped it but don't remember if I specified "including contents and datafiles". The tablespace was empty and there are no datafiles for it. However, the information for this dropped tablespace still shows up in v$encrypted_tablespaces. How do I get that lingering information removed?

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
