Server Administration :: Unable To Claim Space For Operating System?
Sep 15, 2012
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?

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 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?

a newbie dba here..
select TABLESPACE_NAME,
sum(BYTES) Total_free_space,
max(BYTES) largest_free_extent
from dba_free_space
group by TABLESPACE_NAME
/
result output is attached .txt file.
the SYSTEM & USERS table space shows only <10 mb free space. Is it a bad sign? What I should do ?

In normal days size of archives generated in a day is 14-15GB. But since yesterday morning, almost 150GB of archives have been generated and are still getting generated(200MB every 1-2 minutes).
There was a sudden reboot of server yesterday morning. At that time there was heavy load of transactions on database. Can it be a reason that smon is still doing recovery? (I am not sure on this). Also, Undo tablespace is increased from 18 GB to 50 GB since yesterday (autoextend on).
Now we are running out of space for archive file system (can't delete them also until they are transferred to DR) Size of redo log is 200MB. This database supports around 2500 users.
performance wise I don't see any hit. Also wait events are normal. (only few db file sequential read) finding the query/session which are causing this much huge amount of archives?

I have one generic question about space management. I have one table with size of 1TB. This table stored in ORC1 tablespace. This tablespace contains 70 datafiles.
Since it's 10.2.0.4 database. I have dropped this table by using purge
drop table <<table_name>> purge;
Once table drop was completed. When I check the tablespace space it was 100% free but due to HWM was unable to resize the datafile from current size to small size. What was the reason behind this. Is there any process needs to follow when dropping big tables ? like instead of dropping the tables do I need to truncate first & then drop .

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?

In system tablespace ,the max size segment is IDL_UB1$,it is 167M

am using Oracle 10.2.0.4 on win 2008 server SP2. I would like to know if we can set the Segment Space Management feature to AUTO for RBS and Temporary tablespaces. As the data is not permanent in these tablespaces, will it manage automatically?
Presently its Segment Space Mgmt is manual for System, RBS, Temporary tablespaces.

In one of our Data warehousing DB, even though, all the tablespaces' space should keep on at least 1 month, but our leader want us to estimate how much space can free up with db method.
I have referenced
<Administrator Guide> - Reclaiming Wasted Space
[URL].....
I have several questions on reclaim space:
1. It seems that segment adviser give a really cool view to know which segment should be shrink and how much size will free up after shrink. But actually, this need a very a job or manually do this. I have once heard about some query from can estimate this :
A script from MOS, but actually I found this it's not very accurate with segment adviser. This script should report the real space the table occupy, but after shrink space, the space doesn't free up.
SELECT TABLE_NAME , (BLOCKS *8192 / 1024/1024 ) - (NUM_ROWS*AVG_ROW_LEN/1024/1024)
"Data lower than HWM in MB" FROM DBA_TABLES WHERE UPPER(owner) =UPPER('&OWNER') order by 2 desc;
Also there is a script evaluate the tablespace fragments from some people:
SELECT tablespace_name,
SQRT (MAX (blocks) / SUM (blocks))
* (100 / SQRT (SQRT (COUNT (blocks))))
FSFI
FROM dba_free_space
GROUP BY tablespace_name
ORDER BY 1;
if the value is very low, we can coalesce the tablespace. But after I coalesce the tablespace, I can't see any space free up.
From <Concepts>:
Quote:Coalescing extents is not necessary in
locally managed tablespaces, because all contiguous free space is available for
allocation to a new extent regardless of whether it was reclaimed from one or more
extents.
2. is there any good way to estimate how much space we should free up? ( After free up the space , dba_free_space should see this result)

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.

We have separate tablespaces for Tables and Indexes. Also Temp is in different temporary tablespace and UNDO also in UNDO tablespace and Index tablespace contains only Indexes. The tablespace usage for tables is 80% and Index is 91%.There is not enough disk space to allocate for the datafile on our system. I ran a rebuild on one of the Index but now notice the Index tablespace is 98% used soon after the rebuild finished.
How can i free up space for Index tablespace and why does the size of Index tablespace increased after the rebuild.
