Need to find Exact Database Size in MB

Hi
I need to find the Exeact database size the actual space taken by data not the extent allocated by the table. I mean if the extent size is 64k and there is only 2k of actual data sitting there i need to get that 2k answer.
Thanks in advance.

Hi,
Consider using DBMS_SPACE.SPACE_USAGE.
There are lots of examples somewhere on AskTom website.
Regards.
PS: Bear in mind, SPACE_USAGE works with ASSM only. For MSSM you should use another procedures of DBMS_SPACE package.

There you go.

Urgent: How to find out the size in bytes of java object

Hi Experts,
We've a requirement that we need to find out the size of a java object at run time, is there a direct java API to get the size of a composite object in memory?
Here is my requirement: We are adding string objects (which is an xml string of considerable size) into a List. After reaching certain size limit (lets say 5MB) of the list i need to put this data into DB as a CLOB. So every time I add a string object to the list, I need to see if the total size of the list exceeds the limit and if yes, flush the results into DB.
I am not sure if java has a direct API for this, if not what is the beast way to do it, it s critical requirement for us.
It would be really great if someone could help us out.
Thank you,
-Shibu.

Could you explain your actual requirement a little more fully.
1. Is each individual string a separate XML string? Or is it just a fragment? Why would you just concatenate them together into a CLOB? That won't produce valid XML and it won't let you easily separate the pieces again later. So provide a simple example showing some strings and how you need to manipulate them.
2. Are you using these xml strings in Java at all? Or are you just loading them into the database?
For example if you are just loading them into the database you don't need to create a list. Just create a CLOB in Java and append each string to the CLOB. Before you append each one you can check to see if the new string will put you over your length limit. If it will then you write the CLOB to the database, empty the CLOB and start appending again to the new clob instance.
If you explain what you are really trying to do we might be able to suggest some better ways to do it.

How to know the database size

can one tell how to find the database size?

Depends what you mean by database size and how you want the output to look?
Are you referring to the number of rows across all tables of a schema? The number of bytes used by the rows? The number of bytes used by the tablespaces? The number of bytes used by the datafiles? etc. etc. etc. So many options.
Be more clear in your requirements please.

Rebuild Database did not reduce the database size

I just completed a rebuild database. The rebuild completed much quicker than anticipated and in the end the did not reduce in size.
This is my first rebuild and since original installation I have deleted a number of masters. From my understanding thumbnails and previews are not deleted when the master is deleted. In order to delete the thumbnails and previews the db must be rebuilt. Is this correct?
The db is over 31.1gb. The rebuild took approx 10 minutes and when completed the db size was still 31.1gb. There was a message during the rebuild that read "Recovering projects". I was expecting to see stats showing previews and thumbnails being generated in the activity window but don't see it. Has the db been rebuilt?
Thanks for any assistance.

Rebuilding the database is for disaster-recovery, not file maintenance. I certainly wouldn't do it unless something was fundamentally broken and the application didn't run.
"rebuilding" the database seems to do the following:
(1) remove the database file completely (not even to the trash, it destroys the database utterly)
(2) run through the plist files and reconstruct a brand-new database from them all
I checked this (on an empty library) using hard-links from the commandline, and step (1) above scared me sufficiently that I'd only rebuild the database as an absolute last resort.
Now, 31GB seems a lot for a database that only took 10 minutes to rebuild - are you sure you're not telling us the size of the library (to find the database size, right-click on the library and select view-package-contents, then open the 'Aperture.aplib' folder and find the size of the 'Library.apdb' file. That's the file you're changing when you 'rebuild database'.)
If you're telling us the size of the entire aperture library instead, then that size will be completely dominated by the master RAW files you've imported. I'd guess your library will be less than 10MB.
My understanding is that previews are deleted (since they're stored as separate files alongside the master image, if you look in the folder hierarchy), but thumbnails aren't. The thumbnails are aggregated together into one-file-per-project (presumably for speed of access), and I'd guess the space is reclaimed for future use, but the file doesn't get any smaller. That's a classic trade-off for speed-of-access, and users like us are normally very keen on things being fast

Finding exact matches using WITHIN clause or?

We are storing documents in XML format in a CLOB. We need to find exact matches within an element through intermedia. Is there a way we can use the WITHIN clause or a different type of clause to get only exact matches for a phrase?
e.g., a search on 'accord' would not bring back 'peace accord' etc.

Thanks in advance.

google for "sparse files"

Need query to find the minimum size of a datafile

Hi All,
I need to reduce the size of a datafile. Before that i need to find out how far i can reduce the size of the datafile. Please help
DB version:11.2.0.3
OS:AIX 6.1

Below SQL will ask you blocksize (I guess it is default i.e. 8192) :
select 'alter database datafile '''||file_name||''' resize ' ||
           ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) || 'm;' cmd
from dba_data_files a,
( select file_id, max(block_id+blocks-1) hwm
             from dba_extents
            group by file_id ) b
where a.file_id = b.file_id(+)
and ceil( blocks*&&blksize/1024/1024) -
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) > 0
It will tell you upto how much extend you can shrink your datafile.

How to find out the database-size

Hello,
how can I find out the size of the database.
I created the user as below. I defined the size of the database to 2MB. Now I want to know how much is the size of the database.
CREATE USER oemer
IDENTIFIED BY ...
DEFAULT TABLESPACE system
QUOTA 2M ON system;

Actually, since Omer is a veteran poster to the Forms and Reports forums, I doubt that. I think he is making a much more interesting journey: from front-end to back-end.
I'll be a bit more helpful this morning.
Databases are ways of organising disk space to store data. Fundamentally they consist of OS files, data files. The RDBMS handles by grouping them into tablespaces. When we build tables we assign them to a tablespace.
So, the size of the database is the sum of its datafiles. Of course, some tablespaces are used for sorting and holding undo information, so the size of the database for the purposes of persisting data is:
SELECT count(x.tablespace_name) AS total_TS, sum(x.MB) AS total_mb, sum(x.free_mb) AS total_free_mb
FROM   ( SELECT t.tablespace_name, sum(d.bytes)/1048576 AS mb, sum(f.bytes)/1048576 AS free_mb
         FROM   dba_free_space f, dba_data_files d, dba_tablespaces t
         WHERE t.contents = 'PERMANENT'
         AND    d.tablespace_name = t.tablespace_name
         AND    d.file_id = f.file_id
         GROUP BY t.tablespace_name ) x
/The SYSTEM tablespace is special. It is used by Oracle to hold the data dictionary, the definitions of all the objects in the database. It should not be used for storing application objects (it affects the performance, apatrt from anything else). That is why we must not use it as a default tablespace.
CREATE USER oemer
IDENTIFIED BY ...
DEFAULT TABLESPACE ts_users
QUOTA 2M ON ts_users; Cheers, APC

How to find out the size of a database?

I'm not an oracle dba but a report developer. I'd like to find out the size of my database.
Is this possible using simple query?

An oracle database consists of data files, redo log files, control files, temporary files. Whenever you say the size of the database this actually means the summation of these files.
select a.data_size+b.temp_size+c.redo_size+d.controlfile_size "total_size in MB"
from
( select sum(bytes)/1024/1024 data_size from dba_data_files ) a,
( select nvl(sum(bytes),0)/1024/1024 temp_size from dba_temp_files ) b,
( select sum(bytes)/1024/1024 redo_size from sys.v_$log ) c,
( select sum(BLOCK_SIZE*FILE_SIZE_BLKS)/1024/1024 controlfile_size from v$controlfile) d;
here
a is megabytes allocated to ALL datafiles
b is megabytes allocated to ALL TEMP files
c is megabytes allocated to ALL redo-logs
d is megabytes allocated to ALL control files

Note that the size from 01.06.2009 to 01.09.2009 has not changed. Does this mean that my database hasnt grown at all?
How can I determine the exact growth of my database? Im planning to do some projection on how long will it take before my entire disks are consumed so I need to gather some data with respect to my database growth per month.
Thanks in advance

Hi,
Sorry for "interrupt" here.
I'd recommend you to read the Oracle Database Concept Guide or go to any initial training (like ADM505)
There you will find out that with "database" Oracle refers to the physical files.
You can create a DB of 1 TB and that will be the database size, regardless of the data that is "inside".
That means that, at the end, you more or less understood.
DB02 shows the database size, not the amount of data that is inside the database
