Usually we take AWR weekly once. Some times we did ADDM report and ASH.

3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ?
4. What could be the reason for growth? Is there any way to free the space from sysaux table space?

Partition Drop Not Increasing Free Space In Dba_free_spaces?
Jan 16, 2013I am Using Oracle 11.2.0.3. I had a script that droped partitions for a table which should have dropped nearly 30 gb of data. We have data and index tablespace.
Query of dba_free_space showed no change on data tablespace. However, index tablespace showed increase in free space.
select sum(bytes / (1024 * 1024 * 1024)) "Size (GB)" from dba_free_space where tablespace_name ='&tbs_name'
I am using following command to drop partition
ALTER TABLE table_name
DROP PARTITION "partition_name"
UPDATE GLOBAL INDEXES;
What should be done to increase free space shown for tablespace after partition drop?

I guessed that was because of LUN size (it was exceed 2 TB)After that I dinamically shrinked LUN size on our external storage, rebooted and perfomed cfgmgr command on both nodes. But I still have no enough free space.

SQL & PL/SQL :: Delete Bulk Records In Tables From Which Path Can See How Much Space Is Free
May 5, 2010Im a oracle pl/sql developer but I didnt learn oracle as a language. With my sql skills I started working on Oracle.In my project every table has an associated MLOG$ table for it.
For eg.
CREATE TABLE MLOG$_TEST
(
ID VARCHAR2(64 BYTE),
SNAPTIME$$ DATE,
DMLTYPE$$ VARCHAR2(1 BYTE),
OLD_NEW$$ VARCHAR2(1 BYTE),
CHANGE_VECTOR$$ RAW(255)
)
So is MLOG$_TEST oracle's internal table.
Whenever an insert/update/delete happens it is recorded in MLOG$ tables as I/U/D for the priamry key.So if I do a bulk delete of records in tables an entry is made into MLOG$ tables. So deleting old records in a database doesn't free much space.If this is oracle internal table is it advisable to delete from MLOG$ tables too.
My oracle database is mounted on the Linux server.If I delete bulk records in tables from which path I can see how much space is freed.

View 2 Replies View RelatedServer Administration :: How To Reclaim Wasted Space Thoroughly
Mar 26, 2013In 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)

Apr 26, 2011We 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.

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