SQL & PL/SQL :: Fetch Tablespace And Datafile Count With Used / Freespace?

Apr 30, 2013

I'm trying to fetch tablespace and its datafile count along with used space,freespace and total size of a tablespace. I've written a query like this, but the logic is wrong it is giving me incorrect rows. It is running in loops and shows me incorrect number of datafiles.

Quote: select DISTINCT b.tablespace_name "Tablespace Name",count(b.file_ID) "Num of Datafiles",
TO_CHAR( b.bytes/(1024*1024*1024),'990.00') "Total SIZE(GB)" ,
TO_CHAR((b.bytes - sum(nvl(a.bytes,0)))/(1024*1024*1024),'990.00') "Used Space(GB)" ,
TO_CHAR(sum(nvl(a.bytes,0))/(1024*1024*1024),'990.00') "Free Space(GB)"
from sys.dba_free_space a, sys.dba_data_files b
where a.file_id = b.file_id
group by b.tablespace_name,b.file_name, b.file_id, b.bytes,online_status

Server Administration :: Trying To Change Tablespace And Datafile Properties On Fly

Aug 21, 2011

This facility has one last 10g database and a very problematic tablespace and last datafile associated with it. The tablespace was set up with INITIAL_ EXTENT of 131,072 (128K) instead of the more 'normal' 4,194,304 (4M) and NEXT_EXTENT of 262,144 (256K) instead of 4,194,304 (4M).

More worryingly, the datafile has INCREMENT_BY set to 1 (8K) instead of 1,280 (10M) or 2,048 (16M).Has anyone ever updated sys.ts$.dflinit and sys.ts$. dflincr to modify the INITIAL_EXTENT and NEXT_EXTENT, and sys.file$.inc to modify the INCREMENT_BY?

The workspace datafile. Or, what is the most efficient way to take  cold backup for Database that is dedicated for APEX ?

Server Administration :: Minimum Datafile Size Required For Creating Non-system Tablespace?

May 21, 2007

what is the Minimum datafile size required for creating a non-system tablespace?

I am trying to create a tablespace by giving the syntax like,

SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required

SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;

Tablespace created.

The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.

Server Administration :: Tablespaces In Autoextend Settings

I just want to know what are precautionary measures if tablespaces in a database is in autoextend mode. I'm wondering if these tablespaces reached its maximum sizes.

In our case, we are administering a database (turned over by our outsourcer after a 2-year maintenance) with SAP interface, and we noticed that most of it's tablespaces were created with initial size of 2Gb up to a maximum size of 10Gb, all were 'autoextensible'.

My database is OLP system.

My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?

Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.

Server Administration :: Convert Dictionary Managed Tablespace To Locally Managed Tablespace?

Jan 6, 2012

I have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.

The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.

How To Shrink A Datafile

Feb 13, 2013

Database Version :11gR2

I have a tablespace which has around 32gb space consumed. But if i check the used space then its only 16GB. When i tried to resize the datafile it throws the error

ORA-03297: file contains used data beyond requested RESIZE valueAs per my understanding there are not continous blocks which are there in datafile due to fragmentation may be and there by not able to resize it. If i export the tablespace using datapump and reimport this will release the space.

But i want to know if there are any alternative ways to do the same.

COALESCE Or Shrinking Datafile?

Sep 6, 2010

We have quarterly and yearly processes that deletes and updates data for millions of rows crossing different tables. To make room on the file system I would either like to remove empty datafiles (my preference) or coalesce TS to compact the data than remove the empty datafile.

Having said that, any query that can show me if a datafile has any data in it or a query that can show me whether a TS is a good candidate to be coalesced maybe a query with something displaying a percentage as to free and used extents and a YES/NO column whether to be coalesced or not.
