DBMS_Space

I have a partioned table named bUsers and name of partion is Partion1. How can I use DBMS_Space to get information. Please guide me.
Regards,

They are allocated to the segment, but have never been used.
If they have been used, but are now empty, they are no longer unformatted.

Using DBMS_SPACE.SPACE_USAGE

I have a partitioned table that contain one SECUREFILE column (Oracle 11.2.0.2 Linux 64bit).
I would like to check its space usage in order to check if the compression and deduplication will help us to reduce the CLOB column's size.
I've found the following note in metalink: How to Check Space Occupied by LOB Compression
https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=861344.1
However, this link is refered to a regular table, not partitioned.
I've seen in the documentation of DBMS_SPACE.SPACE_USAGE that there is a partition name attribute, but I'm not seem to use the procedure correctly.
I'm trying to run the following code:
DECLARE
l_segment_size_blocks NUMBER;
l_segment_size_bytes NUMBER;
l_used_blocks NUMBER;
l_used_bytes NUMBER;
l_expired_blocks NUMBER;
l_expired_bytes NUMBER;
l_unexpired_blocks NUMBER;
l_unexpired_bytes NUMBER;
v_segname varchar2(30);
BEGIN

DBMS_OUTPUT.PUT_LINE(' Segment Blocks = '||l_segment_size_blocks||' Bytes = '||l_segment_size_bytes);
DBMS_OUTPUT.PUT_LINE(' Used Blocks = '||l_used_blocks||' Bytes = '||l_used_bytes);

DBMS_OUTPUT.PUT_LINE(' Unexpired Blocks = '||l_unexpired_blocks||' Bytes = '||l_unexpired_bytes);
DBMS_OUTPUT.PUT_LINE('=============================================');
END;
And I get this error : ORA-03213: Invalid Lob Segment name for DBMS_SPACE package

What am I doing wrong ? What should I change?
Thanks in advance,
Roni.

Thank you for your link.
I understood from Kyte's example how to use it and now it works.
I used the table name and partition name of the table instead of the lob segment name and the lob segment partition name.
Can you please tell me if there is a query that correlates between the lob segment partition name and the table partition name?
I would like to know what is the lob segment partition name of the table partition 'PART_03_2009' (or what is the table partition name of lob segment partition SYS_LOB_P495) and so on.
In the DBA_SEGMENTS I didn't find any fields that can help me connect between the two.

Dbms_space.auto_space_advisor_job_proc; and performance

oracle 10.2.0.3
redhat 4.5
RAC environment.. 3 nodes
i am having alot of problems direct path sql loading data, so I ran an AWR to look at the waits and my top waits are
library cache lock
row cache locks
each has over 10,000 seconds of wait in the last 4 hours. No one is query the database, all I am doing is running direct path loads.
I then noticed this in my top queries.
I then tried to track down the job that is calling this since its says DBMS_SCHEDULER... i think its the auto_space_advisor_job.
My questions:
1. What is auto_space_advisor_job? Is this from the oem?
2. what could be calling a "Shrink" on the partitions that I am loading? We are not doing this manually.
3. Why would I have 0 executions and 0 CPU for something with 10,000 seconds of wait? Is it all physical IO? Why no executions?
4. Could those wait events be related to this?
5. any suggestions on what to check next? As I said no one else is doing anything in this database. We are just test loading data.

There is insufficient information in what you posted to be sure what the issue is but simple math shows that there are only 14,400 seconds in 4 hours so I would suggest you go to metalink and open an SR.

Space Management - DBMS_SPACE.OBJECT_GROWTH_TREND - how to execute

I am exploring the use of the package DBMS_SPACE and in particular the function OBJECT_GROWTH_TREND.
I have two problems at the moment. I am only able to execute this function when I am logged in as SYS. I would like to run the function as another user but I can't quite work out which privileges I need to grant that user. The documentation says you must have 'SYS' privileges. Execute privilege is already granted to PUBLIC so I can't see that being the problem.
In a test database where I log on as SYS I am able to execute the function however in that environment the function only returns one row with the current size when what I am interested in is a future growth projection. Does anyone know why I would only get one row ? My Oracle version is 10 g Rel 2 and below is an example of the query I used to invoke the function:
select * from table(dbms_space.OBJECT_GROWTH_TREND ('HR','EMPLOYEES','TABLE',NULL,
TO_TIMESTAMP('2008-05-16 11:00:00','YYYY-MM-DD HH:MI:SS'), TO_TIMESTAMP ('2008-06-01 11:00:00', 'YYYY-MM-DD HH:MI:SS'), INTERVAL '1' DAY ))

Hi,
I have some good notes on using object_growth_trend here:
http://www.oracle-training.cc/t_oracle_segment_growth_prediction.htm
Also, consider making your own growth monitor:
http://www.dba-oracle.com/te_table_monitoring.htm
You can also see the growth of the whole database with this Oracle growth tracking script. Below is a great script to display table size changes between two periods.
column "Percent of Total Disk Usage" justify right format 999.99
column "Space Used (MB)" justify right format 9,999,999.99
column "Total Object Size (MB)" justify right format 9,999,999.99
set linesize 150
set pages 80
set feedback off
select * from (select to_char(end_interval_time, 'MM/DD/YY') mydate, sum(space_used_delta) / 1024 / 1024 "Space used (MB)", avg(c.bytes) / 1024 / 1024 "Total Object Size (MB)",
round(sum(space_used_delta) / sum(c.bytes) * 100, 2) "Percent of Total Disk Usage"
from
dba_hist_snapshot sn,
dba_hist_seg_stat a,
dba_objects b,
dba_segments c
where begin_interval_time > trunc(sysdate) - &days_back
and sn.snap_id = a.snap_id
and b.object_id = a.obj#
and b.owner = c.owner
and b.object_name = c.segment_name
and c.segment_name = '&segment_name'
group by to_char(end_interval_time, 'MM/DD/YY'))
order by to_date(mydate, 'MM/DD/YY');
Hope this helps. . .

Dbms_space.unused_space

I have a database 8k block size. Tablespace initial extent is 40K.
I created a table
D1
CREATE TABLE D1
( RID NUMBER, TABLENAME VARCHAR2(30 BYTE)
Pct free = 10.
No data is currently inserted into the table.
However when I use dbms_space.unused_space
DBMS_SPACE.UNUSED_SPACE (
p_owner,
p_segname,
p_type,
l_total_blocks,
l_total_bytes,
l_unused_blocks,
l_unused_bytes,
l_last_used_extent_file_id,
l_last_used_extent_block_id,
l_last_used_block,
l_partition_name);
Unused space
l_total_blocks--> 5
l_total_bytes--> 40960
l_unused_blocks--> 2
l_unused_bytes--> 16384
l_last_used_extent_file_id--> 16
l_last_used_extent_block_id 497199
l_last_used_block--> 3
5 blocks are allocated 8k * 5 = 40k which is the initial extent size. But I get 2 blocks that are unused
How do we determine the amount of space oracle uses for table management?
Isn't 24K alot.
Thanks in advance for all the help.

This amount of 'unused space' is meaningless, overall considering today databases can hold Tb and Oracle is ready to accept Eb. After the amount of unused blocks you are reporting I assume you are working on a locally managed tablespace with manual segment space management. have you tried this test on an automatic segment space managed tablespace?
Meaningless, unless you are planning to create thousands of tiny tables, and even in this case, from a practical perspective, the cost of storage is not the same as it used to be a decade ago.

DBMS_SPACE ASA_RECO_ROW Record Type Definition

Hi All,
Do you have any idea where we can find the definition of the mentioned packages? Here is the description from Oracle:
DBMS_SPACE
Thats fine, but we would like to select it from data dictionary view.In GUI tools we are able to select metadata, but how in sqlplus?
thanks if somebody could help me
Kind regards

Anything else rather than: select dbms_metadata.get_ddl('PACKAGE_SPEC','DBMS_SPACE','SYS') from dual; ?

Maybe not the best example but as you can see,
for every switch to a different partition I get this EXCEPTION msg.
The output seems correct otherwise.
I can create the message several different ways!

DBMS_SPACE.OBJECT_GROWTH_TREND without Diagnostics Pack

Hi ,
Can i use DBMS_SPACE.OBJECT_GROWTH_TREND without Diagnostics Pack? As per the docs this procedure uses AWR for information retrieval.
Also I've seen that there are multiple bugs related to this in <10.2.0.3. Can some one share their experiences with this option.
My objective here is to observe past object growth at database/object level. This seems to be the ONLY option provided by oracle for this.Any other hints apart from custom scripts.
Thanks
Ravi

Thanks for the info Brain.
As per the licencing docs AWR is part of Diagnostics pack. I'm not supposed to access any AWR tables without proper licence. It also mentions set of packages which will use the AWR information and i'm not supposed to use those packages as well. But no where in the licencing document there is a information about DBMS_SPACE package.
Having said all this, licencing doc also mentions that there are few tables/view that start with DBA_HIST, which can be used WITHOUT licence.
I need to know if there is any clear YES or NO kind of information for my question. Any information you have will be highly helpful.
Thanks,
Ravi.M

DBMS_SPACE(9i) for tablespace growth trend..?

Hello,
for 10G, dbms_space.object_growth_trend() can expect table's growth....
for 9i (9.2.0.6 in Sun9) database, is there any friend has experience know how to do for the following purpose:
1. How to expect tablespace growth? say, to accommodate new data for the next 30 days we have to increase tablespace A by X GB, tablespace B by Y GB, … etc
2. How to expect database level growth? say, we need XXX GB more to accommodate new data for the year YYYY
3, Is there any way to Initialize (if possible) Segment Advisor with the information about segment trends we have already collected in 9i
Thank you in advance
Jerry

Hi..
AFAIK in 9i you can't find the Subprograms like object_growth_trend() package in dbms_space.
How to expect tablespace growth? I think that you will have to maintain a sheet of the tablespace usage.Daily you will need to maintain the tablespace size, used and free size of tablespace.Ans after few days of observation you can predict the approximate amount of size being filled up in a day.
You can use the below query to know the used and the free space in the tablespace.
select df.tablespace_name tspace,
df.bytes/(1024*1024) tot_ts_size,
(df.bytes/(1024*1024) -sum(fs.bytes)/(1024*1024)) Used_ts_size,
sum(fs.bytes)/(1024*1024) free_ts_size,
round(sum(fs.bytes)*100/df.bytes) free_pct,
round((df.bytes-sum(fs.bytes))*100/df.bytes) used_pct1
from dba_free_space fs, (select tablespace_name, sum(bytes) bytes from dba_data_files group by tablespace_name ) df
where fs.tablespace_name = df.tablespace_name
group by df.tablespace_name, df.bytes
order by 1
2. How to expect database level growth? Again same, you need to maintain a sheet for it.Use the below query
select sum(bytes/1024/1024/1024) Physical_size_gb from dba_data_files;
select sum(bytes/1024/1024/1024) Actual_size_gb from dba_segments; 3, Is there any way to Initialize (if possible) Segment Advisor with the information about segment trends we have already collected in 9iNo.

Dbms_space.verify_shrink_candidate

Hi,
in 10gR2how can I find the table which can be shrinked using dbms_space.verify_shrink_candidate
Many thanks.

Again a package function that is not documented :(
anyway, here is what i found out. I have garbled the table name and other information.
SQL> declare
2 x boolean;
3 begin
4 x := dbms_space.verify_shrink_candidate ('X','ABC','TABLE',100000000);
5 if x = true then
6 dbms_output.put_line ('yes');
7 else
8 dbms_output.put_line ('no');
9 end if;
10 end;
