Free space requirement in Oracle database

In my oraganization SAP application running with oracle as database. now our database is 1300 GB and right now 90 GB space free in database (92 % used). since System implementation we kept this free space upto 90GB by adding datafiles every week. I am newbie and want to know that how much free space oracle requires for better performance. can I stop adding datafile .

But in SAP application,SAP has its own intelligency for database monitoring. we only add datafile in database for its space management.Now there is no space in our file system to add any of the datafile. In database 90GB out of 1300GB free. so what happen if database growth furher? database will get hang?I am not sure at all what SAP recommends but there isn't any thing that says that X amount of space should be left free. Oracle has come out with the alert mechanism that can help you to get the alert when the free space goes below the specified limit that you mention but more than the performance, it's the availability IMO that's going to be effected. For example, if you have run out of space, you won't become more slow or faster but you won't have space to do any further writing and that's going to cause the operations to be halted as long as you won't solve the issue by adding more space or by adding new files. So , saying that database would hang would be incorrect, not operational, yes!
Just my 2 cents

Free Space Information On Harddisks Not Realtime

Hi i have an problem i have some dvd's images stored on my harddisk. when i burned the dvd's images to dvd i removed the dvd's to the trash and emptyed the trash. but when i check the finders free disk space it shows the same amount of free space like before i removed the dvd images(about 12gigs)
after rebooting the info is fixed again but lets tell it this way, i like the slumber option a lot.
thanks for your help!

Hi OMEGA_ReD,
this is a known problem of MacOS X since it's initial launch several years ago. After this long time we tend to call this a "feature" instead of a bug
Another one of these annoying never-get-solved bugs is the fact that the Finder does not correctly apply view-options to Finder windows, regardless whether you select "Apply to all windows" or not - it simply does not work (http://discussions.apple.com/thread.jspa?messageID=3678099&#3678099)

Doubt in considering temp tablespace's free space

Hi All,
Database: oracle 11.2
Operating System: AIX
I want to know how much free space available in my temp tablespace
I ran below scripts
select sum((bytes_free)/1024/1024/1024) GB from v$temp_space_header
+52.904296875+
select (tablespace_size)/1024/1024/1024 tablespace_size_in_gb,
+(allocated_space)/1024/1024/1024 allocated_space_in_gb,+
+(free_space)/1024/1024/1024 free_space_in_gb+
from dba_temp_free_space
tablespace_size_in_gb: 98.9990234375
allocated_space_in_gb: 46.0947265625
free_space_in_gb:151.81640625
So my doubt is which one from above two script gives actual free space information ?
Also in dba_temp_free_space view why free space size > tablespace size ?

v$temp_space_header shows you how big the temp tablespace has got since the database was restarted. It doesn't give you the current free/used space.
See the link for dba_temp_free_space, but I think it may be the way it reports free space which is why you're seeing it as more than the actual tablespace. As you can see form the description "space that is currently allocated and available for resuse" is calculated for both allocated space and free space.
http://docs.oracle.com/cd/B28359_01/server.111/b28320/statviews_5056.htm
>
ALLOCATED_SPACE = space that is currently allocated and used + space that is currently allocated and available for reuse
FREE_SPACE = space that is currently allocated and available for reuse + space that is currently unallocated>
I use the below script which I've plagiarised from somewhere ages ago to get the used/free temp space.
SELECT   A.tablespace_name tablespace, D.mb_total,
         SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_used,
         D.mb_total - SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_free
FROM     v$sort_segment A,
         SELECT   B.name, C.block_size, SUM (C.bytes) / 1024 / 1024 mb_total
         FROM     v$tablespace B, v$tempfile C
         WHERE    B.ts#= C.ts#
         GROUP BY B.name, C.block_size
         ) D
WHERE    A.tablespace_name = D.name
GROUP by A.tablespace_name, D.mb_total;

Calculating free space in tablespace

Oracle 11.0.1.7:
I am trying to calculate free space in the tablespace but I am not sure if Allocated Space (bytes_used) also has some free space that doesn't get reflected in the query below. Is it correct to assume that bytes_used is the space allocated to extents but may not have been really used (no data or LOB) yet? How do I calculate space that's currently been used by row data, index data or blob data?
I am currently using below query:
select     a.TABLESPACE_NAME,
     a.BYTES bytes_used,
     b.BYTES bytes_free,
     b.largest,
     round(((a.BYTES-b.BYTES)/a.BYTES)*100,2) percent_used
from
          select      TABLESPACE_NAME,
               sum(BYTES) BYTES
          from      dba_data_files
          group      by TABLESPACE_NAME
     a,
          select      TABLESPACE_NAME,
               sum(BYTES) BYTES ,
               max(BYTES) largest
          from      dba_free_space
          group      by TABLESPACE_NAME
     b
where      a.TABLESPACE_NAME=b.TABLESPACE_NAME
order      by ((a.BYTES-b.BYTES)/a.BYTES) desc

DBA_FREE_SPACE give you the free space information which has not been allocated to any segment. The segments can also have free space in their allocated space and in order to find that, use DBMS_SPACE.SPACE_USAGE procedure. To find out free space in LOB segments refer to metalink doc: 386341.1

DB Space Information in CCMS

Hello,
please, did everybody know, how it would be possible to get the Information about the Space ofg the data base into the CCMS? So i need for an reporting issue the information about used Space and free space of the whole data base. When I look into the Alert tree there is just information to the tablespaces ...
I found the function module DB6_His_Overview, but this one create only webdynpros.??
Thanks for helping me
kind regards Lars

Hi Lars,
this function module DB6_HIS_OVERVIEW is the dataprovider of the DB02 overview screen of database history. There are two disadvantages if you use it
1. It does not reflect the current state but provides only data of the last collected history
2. It is not an officially relased function module and might change in the future
Alternatively you could use the new adminstrative SQL tablefunctions and views provided by DB2 9 via some EXEC SQL. E.g. there is the SNAPTBSP_PART administrative view. It returns used and free space information in terms of PAGES. So you need some join with SYSCAT.TABLESPACES like
select sum(v.tbsp_used_pages * (s.pagesize / 1024 ) )
from SYSIBMADM.SNAPTBSP_PART as v,syscat.tablespaces as s
where v.tbsp_name = s.tbspace
For DB2 8.2 this view is not yet available but there is a similar table function snap_get_tbsp_part, which will also work
Best regards

How to calculate the percentage of free space for a table in Oracle

okay, I am a little confused here. I have been searching the web and looking at a lot of documents. What I basically want to find out is this, how do I calculate the difference between the number of bytes a table is using and the total bytes allocated to a table space (going that way to get percent free for a particular table). So I need a byte count of a table and total table space and the percentage difference. I have been looking at the DBA_TABLES DBA_TABLESPACES and DBA_SEGMENTS views. I have tried to calculated the space as num_rows * avg_row_len (if I am wrong, let me know). I have been trying to compare that calculation to the number in DBA_TABLESPACES and DBA_SEGMENTS. I am just looking for the total space allocated to the table space that the table sits in (seem logical right now) to make the percentage value work. Thus I want to be able to track the table as it grows as compated to the table space it sits in to see a value as it changes over time (days, weeks, etc.) each time I run this script I am working on.
Can someone get me straight and help me to find out if I am looking in the right places. Any advice would help.

You can use a little modified version of dbms_space from Tom, show_space. Have a look,

I use this to find the space allocations.
Just read your post again,this is not going to show you the percentage of the free/used space. This is going to be the number of blocks which are free/used. For the growth trend, you can look at (in 10g) Oracle EM. It has added now,Segment Growth Trend report which can show you for each object,comparing to the allocated space to the object,how much space is being used by it.

How SMON coalesces free space in oracle 9i and 10g

how SMON coalesces free space in oracle 9i and 10g?
Is it doing same as it was behaving in oracle 7 like looking through free extent table every five minutes (sys.fet$) to see if there are any adjacent free extents that can be coalesced into a single extent, and on every 25th cycle (i.e. every two hours and five minutes) it looks at the segment table (sys.seg$) to see if there are any temporary segments that need to be eliminated, as explained by jonathan lewis?
what are extent and segment tables available in oracle 9i and 10g like sys.fet$ and sys.seg$ in oracle7?

How do I fix it?Add Space.
Looks like you've got a less than 4G total for / with about 420MB free. That's nowhere near enough space, out-of-the-box the datafiles alone take about 1G.
Try bumping sda2 up another 4G, or add a (at least) 4G partition and mount it at /usr/lib/oracle

================================================================
The corruption is being reported in a free space block of the ORDER_DATA_01.DBF.
I’ve checked all the tables (and indexes) in this tablespace and none report corruption.
=====================================================Is there any action I need to take to remove corruption at this point?It is not affected any operation on the database yet.
What is the best way to do get rid of the corrupt block, without dropping and rebuillding the full tablespace(which is around 6 GB -total of 3 datafiles)
Thanks a lot

Can RMAN recover the datablock from this cold backup(which is a week old, the data file was not corrupted then) ?Please note that to do the recovery, you would need the backup and the archivelog files since the backup. Think about what you are asking to do. Its a single block whose recovery you are asking from a week old backup which obviously would be on an much older SCN compared to the rest of the database. How would you make that block consistent with the rest of the datafile. If you don't have archivelog in that db whose block is corrupted, you may forget that block and any data that it might ever had. Also, please read the documentation about the block recovery which explains the requirements very clearly,
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmblock.htm#BRADV89784
From the above link, 1st point,
The target database must run in ARCHIVELOG mode and be open or mounted with a current control file.HTH

Retrieving free space in oracle 8i

hi,
i am having 30 gb oracle 8.1.7.2 database. by the weekend we are gonna purge around 60% of data from it. we want to use the freed space for new object. the downtime avaiable for app. is very less. so we can't go with exp/imp to retrieve free space. is it possible to do it some other way because i am having a doubt that oracle 8i does not release the space freed by deletion of recording for creating new objects. please help.

Hi,
In order to do that you can use 2 methods:
1/ CTAS
. CREATE TABLE new AS SELECT * FROM old WHERE <lines_to_keep>
. DROP TABLE old;
. ALTER TABLE new RENAME TO old;
2/ Purge data as you whish
. DELETE FROM tabname ... ;
. COMMIT;
. ALTER TABLE tabname DEALLOCATE UNUSED;
HTH,
Yoann.

Free Space on Oracle Mount Points

Hi,
In my production environment, which is on ECC 5.0 on HPUX and Oracle DB, my mount point for the Oracle DB files has reached 90% plus......
What is the amount of free space that should be available on these mount points at any point of time. Will there be a performance issue in the above case.
Inputs on this will be appreciated.
Regards
Alfred D'Souza

Hello Alfred,
> What is the amount of free space that should be available on these mount points at any point of time. Will there be a performance issue in the above case.
Personally i try to keep 4 GB free space for each sapdata (for big systems), for smaller i only keep 1 GB.
Performance issues depends on your storage. If you have SAN storage with caches.. performance will be not affected, but if you have local disks it depends on the data striping and the i/o intensive actions.
But in general i say, the performance will be not affected by the free space.. it will only be affacted by the i/o actions and the distributed data over all sapdatas.

System information shows free space as taken up by apps

Hey all,
I don't have any issues with the functionality of the drive, only that the free space shows up as used by apps.
Any ideas why this could happen? If it's an app causing this I can let it go. Or is it 'System Information' who's misbehaving?
Tried a disk repair in osx recovery, tried deleting large files, nothing changes it
Thank you!
Eddy

BR1049W Not enough free space in /oracle/SID/sapdata

Hi Everybody,
I am trying to extend a tablespace through BR*tools. However I'm getting the Warning :
BR1049W Not enough free space in /oracle/SID/sapdata1 for total maximum size of all database files of tablespace...
As you could see below, I have still about 100 GB free on this logical volume.
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/sapdata_lvSID 899.88 99.97 89% 179 1% /oracle/SID/sapdata1
I wanted to add a datafile (size = 32GB), it didn't work.
Best regards
Latif

Can you please provide the SQL statement the brtools is issuing when adding the datafile. Probably ,for all the datafiles which are in /oracle/SID/sapdata1 , if the max size is added up , then the value is greater than the filesystem size. Please check in dba_data_files the maximum size upto which datafiles in sapdata1 can extend.
Use this to check:
select sum(MAXBYTES)/1024/1024/1024 from dba_data_files where FILE_NAME like '%sapdata1%';
if the value returned + the new datafile max size is > file system size you will get the above error.
