Shrink / reclaim space

what is the best proceedure to reclaim or shrink a 109GB of reclaimable space? w/o using alot of disk space.
tyia

1. ALTER TABLE tablename SHRINK SPACE COMPACT;
-> DML operations and queries can be issued during compaction.
2. ALTER TABLE tablename SHRINK SPACE;
-> DML operations are blocked when the HWM is adjusted.
When you specify the SHRINK SPACE COMPACT clause, the progress of the shrink operation is saved in the bitmap blocks of the corresponding segment. This means that the next time a shrink operation is executed on the same segment, the Oracle database server remembers what has been done already. You can then reissue the SHRINK SPACE clause without the COMPACT clause during off-peak hours to complete the second phase.

Need to reclaim space from dwh tables.

We have couple of large tables (> 200G) in one of the DWH schema. I need to reclaim space on the mountpoint.
I have used ALTER TABLE <> MOVE COMPRESS; command to compress these tables.
Now in dba_segments it is showing the improvement. 200g table came down to 60G. However I am not able to see any change in datafile and in mountpoint, I beleive due to the HWM.
I tried shrink for the tables, it did not help.
Could you please suggest any other approach.

Can't reclaim space in tablespace after deleting records

Oracle 11gR1 RHEL5 64bit
Hi.
I am having trouble reclaiming space from a tablespace after having deleted all (thousands) of the records from a table (which resides in that tablespace). I have tried the following options to no avail:
- Alter table <table_name> shrink
- purge tablespace
- purge recyclebin
This table has several LOB columns and is using securefiles. I don't know if that has something to do with it or not. The tablespace is locally Managed and Segment space management is set to AUTO. Below is the create table command:
CREATE TABLE IIQ.DICOM_OBJECT
DICOM_OBJECT_RID NUMBER CONSTRAINT NN_DICOM_OBJECT_DICOM_OBJ_RID NOT NULL,

OK, so you did a SHRINK SPACE CASCADE? Not just a SHRINK SPACE?That is correct.
What makes you believe that there is more space that can be reclaimed? Well, what I don't understand is that when a table (and only that table) was assigned to a specific tablespace whose data was completely removed is showing as if the data is still there...at least when you look at the tablespace. If all the rows of a table are removed, then shouldn't the tablespace size go down? There was 95 GB of data in that tablespace and all from that one table, which was completely emptied. However, it still shows the tablespace as being 95GB full.
Can you post the size of the table segment and the LOB segments as well as the size of the actual data in the table and the LOBs?Can you tell me which views you would like to the see the data from ? dba_lobs, dba_segments, etc... I want to make sure i have the right query for you.

Reclaim space from DBFs

Hi All,
I have one query regarding tablespace reclaim space. I have users tablespace which is having 5 dbfs. Some of the DBFs of USERS tablespace having autoextend on with max size 32G and some of the DBFs not having autoextend on and maxsize 4G.
Now when I checked the USERS TBS through EM , I come to know only few MBs out of 20G are in used in 3 DBFs of USERS tablespace and rest of 2 dbfs are in good in use. Now I want to reclaim the space from 3 dbfs say users03,users04 and users05. users01 and users02 are properly in used. I want to reclaim the space from 03,04 and 05.
can I have any idea how to reclaim space from dbfs? I try with alter database datafile ...resize but giving error "ORA-03297: file contains used data beyond requested RESIZE value".
please suggest me,
Thanks...

Yes, I think you are understanding how it works. For a visual example, if this is your data file:
XXXX--XX-XXXX-XXXX-XXXX-XXXXXXX-----------------
and you delete some data
XX----X--------X------------------X-----------------
The datafile can be resized only down to
XX----X--------X------------------X
Which tools are available to do this efficiently vary by database version, for example in my 9.2.0.6 database I can use exp/imp, CREATE TABLE AS SELECT, rebuild indexes (mostly) online, exp/imp, move LOBs around with ALTER TABLE ... MOVE LOB, or other strategies - some of these are more work than others, and all will take some amount of time. In 8i There are fewer options; beginning with 10g data pump and DBMS_REDEFINITION are available; in 11g the index rebuilds don't lock the data, so the time may be less of a concern.
Before you even spend the time to shrink these data files, consider the space needs for USERS. If the extended size was a one-time thing, then shrinking datafiles may be justified. If USERS may grow that large again then a data file shrink is a lot of work for little gain.

Benefits of Reorg to reclaim space in Oracle

Hi All,
I have archived and deleted records from few big tables from my database, now how want to reclaim space by doing reorg.
Can anyone please guide me how to find out If I can reclaim some space by doing reorg.
What are the queries which can help me find out space used before and after reorg.
Thanks & Regards,
Deepak

You cannot do much with a long raw short of export/import it - so you would export it, drop the old table, create a new one in the new tablespace and import with ignore=y. Other objects can be online redefined into this tablespace - or indexes if they are in there can be rebuilt online into this new tablespace, but moving the long raw is going to be offline.
Source:Ask Tom &quot;Reclaim space&quot;
Shrink, Move, CTAS (Reclaiming space) do not works for LONG datatype. For LONG dataype export/import is the best and feasible solution.

Reclaim space at OS level.

Dear all
I have performed following activities to reclaim space at database level on development system but I am quite suspicious about to reclaim at OS level.
1) Choose baldat table for REORG candidate
2) Size of table before deleting record was 11GB
3) Delete record from it using slg2
4) Offline REORG done
5) Table size is now around 2.5GB
6) Since database is DB9.7 and tablespace is in DMS type, I need to issue two command as following to reclaim space at DB and OS level.
     alter tablespace TCD#BTABD lower high water mark
     ALTER TABLESPACE TCD#BTABD REDUCE (ALL CONTAINERS G/K/M)
7) I have issued only first command to lower HWM which freed up space at Database level.
     Checked from DBACOKPIT to see tablespace status as following
     Tablespace Name     KB Total     Percent Used     KB Free     Page Size (KB)     High-Water Mark (KB)
     TCD#BTABD            16121856        33.25           10762016       16                         5359712
Now my query is I want to reduce it down by 9GB at OS level so which figure I have to put (??) on the following. Is there any harm to execute this command on the fly which causes database issue???
      ALTER TABLESPACE TCD#BTABD REDUCE (ALL CONTAINERS ??? G/K/M)
Thanks

Re-organizing table to reclaim space

Hi All,
Recently we have purged data from some tables in the database.
Is it necessary to reorganize the table to reclaim space after we remove the data from the tables? How can we find out that the table can be reorganized?
Database version:11.2.0.2
OS version:AIX

how did you purge the data?
have you used delete or truncate.
please check space under dba_segments for particular object which was purged.
from 10g onwards we have segment advisor.
The segment advisor performs analysis on the fragmentation of specified tablespaces, segments or objects and makes recommendations on how space can be reclaimed. The advisor is accessible from Enterprise Manager (Home > Advisor Central > Segment Advisor) or from PL/SQL by using the DBMS_ADVISOR package.

Please close the thread after marking it helpful or correct if you get the answer.

Query needed to find reclaimable space in db

10.2.0.4
Linux 4.
Hi.
On a test database I suspect there are a lot of objects that are not needed that are taking up valuable disk space. These may include tables that are backups of tables etc.
Does anyone have a tested query to seek out these objects? They will have probably been named test, or backup, etc.
Thanks in advance.

Apparently you want to find candidate junk objects to discard. This is a quite specific subset of the overall issue of finding reclaimable space. In the overall issue a lot of attention should be paid to whether temporarily supressing some free space (due to massive deletions, for example) is worthwhile. In the subset you inquire about, if you can identify the junk it is almost certainly a win to discard it. Some shops have naming standards for objects not officially sanctioned in the production schema. My favorite is the prefix JUNK_<initials>_, so that all the objects can be found quickly with the wildcard on the efficient end of the query, as in:
select owner,object_name,object_type
   from dba_objects
   where object_name like 'JUNK%'
   order by object_name;
or
select owner,object_name,object_type
   from dba_objects
   where object_name like 'JUNK_MWF%'
   order by object_name;Even just the naming convention makes it easy to identify candidate objects, and if you have rules about creating "JUNK" objects such as maintaining a log with expiration dates and purposes, then further inquiry is easy. Having the object's sponsor's initials at hand makes a personal interview possible if the log entries are not useful, and if an expiration date is provided you can simply use the log table as a list to control deleting discardable objects.
In your case you are dealing with catching the horses after the stalls and barn door were left open. Up to now I've written more about closing the barn door for future efforts.
For the cleanup, the similar query with the like predicate '%TEST' and other candidate name templates should suffice. Depending on how creative folks have been spelling TST and BCKUP, you may want to play with the regex functions. Just be sure to treat the generated list as a list of candidates. Depending on the length of the list you can then either generate the appropriate drop statement by type or simply type them into a file for review and execution. Sending out the list of objects to be deleted with a reasonable warning period is highly recommended, since having the ability to create unknown objects often implies sufficient rank to ignore organizational rules. Whether creating an individual object export prior to the drop will vary from site to site and by the size of the object to be dropped.
Good luck,

Shrink the space between rows in a report

hi all,
As the subject says, I am trying to shrink the space between rows in a report so that there is no space between rows when i print it. Does anyone know how to do this? Do I need to make a custom report template for it?

The space between rows in a report in Apex is frequently determined by the cellpadding and cellspacing attributes of the TABLE tag that makes up the innermost report area, but there also other factors that may affect the resulting area, so one has to look at the specific case and see what is determining the final result, bearing in mind that it's quite possible that two browsers will display the same thing differently.
At any rate, spacing is normally controlled by fine-tuning margin and padding properties in CSS.
As CSS stylesheets, as per their name, are applicable in cascade, you can add your own CSS stylesheet in the page header (after the built-in ones).
If you are using Firefox (with Firebug add-on installed) or Chrome or Safari, you can easily experiment with these properties and see the effects by temporarily setting or unsetting certain values and when you are satisfied, you can copy the resulting definitions into your stylesheet.
The fact you want to make some adjustments only when printing can be solved by means of the @media rule inside the stylesheet or by linking different stylesheets depending on the value of the media attribute in the LINK tag or by dynamically pointing to different stylesheets depending on whether Apex is rendering the page in printer-friendly mode or not.

Clear FND_LOBS to reclaim space in applsysd

we have on LOB in applsysd tablespace which is taking 20% space in tablespace. I do not need this, please advise how to move to reclaim space on it.

Reclaim space FND_LOBS

Hi All,
EBS R12.1.3 , DB 11.2.0.2 RAC 2 nodes
I have recently Reclaimed the space from FND_LOBS table , but even after this , Total allocated space showing 135 GB , and when i see the space occupied is 61G only, please help in this how can i get back the space. I followed note Reclaiming unused space in an E-Business Suite Instance tablespace (Doc ID 303709.1)
select

How can I verify if SHRNK or MOVE will reclaim space?

Hi all,
I need to optimize a 9.2 and a 10.2 database.
I suspect fragmentation to be one of the causes of slowness (some queries do a lot of full table scan), but I want to rebuild only the objects which really contain unused .
How can I verify in advance if an ALTER TABLE SHRINK or ALTER TABLE MOVE will really reclaim free space? I'd like to verify if some segments are good candidates for shrinking rather when do an "ALTER TABLE MOVE" on the whole database...
Is DBMS_SPACE.SPACE_USAGE the only thing I can use?
thanks in advance for every answer.

Normally I use this package from Tom Kyte to check the space usage of the object.
create or replace procedure show_space

p_owner   in varchar2 default user,
p_type    in varchar2 default 'TABLE',
p_partition in varchar2 default NULL )

Hired a movie, completed download, got stuck processing, can't reclaim space

Here are the steps that led to my issue:
1. Hired a movie from my iphone 5
2. began download
3. Checked download an hour later and status was 'Processing.....'. Checked
Movies and no Hired icon present in bottom nav
4. 6 hours later, still in Processing
5. Reset phone (held power+menu button util apple logo appears)
6. check download status in itunes store and download starts again but fails due to not enough space
7. Check Movies and rental icon is in Nav and hired movie is listed. Click okay but movie fails to play.
8. Delete movie
9. Go back to itunes download and start to download again
10. Download fails due to not enough space. The deleted movie was removed from the a Rental section but the space associated with the failed download was not reclaimed.
Any tips?
Thanks

Looks like they've changed the screens overnight - they were different yesterday, you had a set of options on the left-hand side of the page and didn't need to enter a serial number.
You could instead try the 'report a problem' link from your purchase history (assuming that hasn't been changed as well) : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that film and use the 'Report a Problem' link.

Reclaim space from empty queues

I'm using Glassfish 3.1.2 that comes with embedded OpenMQ (4.5.2 (Build 2-d)).
When I put persitent messages into a queue the messages are saved to disk and they take space.
When I receive messages from queue the space on disk is not reduced.
Is there a way to reclaim that space?
So for example, if a queue with 100 messages takes 50MB on disk, then the messages are received from the queue and the queue still takes 50 MB on disk. I want it to take 0MB (or some small number).

Hello,
Run following query by replacing with your table name and appropriate one partition range. In TOAD, you can anaylze or collect stats on partition it will update the partition tab with latest infornation meaning 0 zeros for truncated partition.
select count(*) from yourtablename where date_column between to_date('20090101,'YYYYMMDD') and to_date('20090102','YYYYMMDD') ;Regards
