Free space available in tablespace
Hi, Any one help me how to check how much free space available on a particular Tablespace. Appreciate if you provide query.
Thanks & Regards
Bhaskara
This SQL will return free space by datafile in the tablespace.
SELECT a.name FileName, a.status, c.bytes/1024 CurrentSize, a.create_bytes/1024 SizeCreated,
sum(b.bytes/1024) FreeSpace, max(b.bytes/1024) LargeFragment
from sys.v_$datafile a, sys.dba_free_space b, sys.dba_data_files c
where a.file# = b.file_id(+)
and a.file#=c.file_id
and c.tablespace_name='XXXXXXXXXXXXXXXXX'
group by a.name, a.status, c.bytes, a.create_bytes
ORDER BY a.name;
I just posted an integrated set of GUI tools to administer the Oracle database.
One of the many functions is to view and maintain all database objects including tablespaces and datafiles. It also has a graphical function to monitor space allocation for tablespaces. You may need same help to get started, so feel free to contact me ([email protected]). The link is http://www.barsoft.net/

To know the amount of free space in a tablespace
hi,
I'm learning oracle 9i release 9.2.0.1.0 .I'd created a tablespace 'TOOLS' for being used as the default tablespace for Statspack.
I wish to know the amount of free space available in this tablespace. For this purpose I ran the following query but there was no rows selected :-
SQL> select tablespace_name,bytes from dba_free_space
2 where tablespace_name='TOOLS';
no rows selected
SQL> select name from v$tablespace;
NAME
CWMLITE
DRSYS
EXAMPLE
INDX
ODM
SYSTEM
TOOLS
UNDOTBS1
USERS
XDB
TEMP
Can anyone tell the reason for this.I tried your query
SQL> select TABLESPACE_NAME,
2 sum(BYTES) Total_free_space,
3 max(BYTES) largest_free_extent
4 from dba_free_space
5 group by TABLESPACE_NAME;
♀TABLESPACE_NAME TOTAL_FREE_SPACE LARGEST_FREE_EXTENT

How to find free space in a Tablespace?
Hi,
I have a limited access to objects in my database ( do not have access to many tables).
I have been allocated 300GB of size in my tablespace which allows me to create my objects.
Now, I want to find out how much of this tablespace size allocated to me have been used up. I do not have access to dba_data_files or dba_segments.
Is there a way out for me? Could anyone show me a way please?This query will give you the required information but it makes use of DBA tables.
SELECT B.TABLESPACE_NAME, TBS_SIZE SIZEGB, A.FREE_SPACE FREEGB
from (select tablespace_name, round(sum(bytes)/1024/1024/1024 ,2) as free_space
from dba_free_space
GROUP BY TABLESPACE_NAME) A,
(select tablespace_name, sum(bytes)/1024/1024/1024 as tbs_size
from dba_data_files
group by tablespace_name) b
where a.tablespace_name(+)=b.tablespace_name;
However, you said that you are aware of your tablespace details so the above query can be modified to get the free space in your tablespace. Now I am using user_frees_space and not dba_free_space. Generally user* tables are and should be made accessible to the users.
select tablespace_name, round(sum(bytes)/1024/1024/1024 ,2) as free_space
from user_free_space
where tablespace_name = 'Your tablespace name'
GROUP BY TABLESPACE_NAME;

Hi,
in DB version 9.2.0, after all transactions are committed, the occupied blocks in UNDO tablespace will be free or not ?
The same just after startup, before any transaction the free space in UNDO tablespace would be at max ?
Many thanks.Hello Dear copy this script and paste in the sql prompt and it will show your how much total space table have, or how much is used and how much it is free
SELECT Total.name "Tablespace Name",

Can't save file on iOS device with low free space available
Hi,
I was using SharedObject to save settings in my game. However, recently I discovered on one of our devices it doesn't work. I've found somewhere on this forum discussion that air can't save sharedobject when available space is lower than about 300mb (link here: Bug#3711301 - sharedobjects fail when available storage is low). On my iphone it's about 40mb, but file, which I want to save is just 2 variables.. persistenceManager doesn't work too (well i've looked at source and it's just using SharedObject). So i've decided to just write file by myself:
declarations:
public var mute:Boolean = false;
public static var fullId:String = "";
then in constructor:
flash.net.registerClassAlias("Settings", GameSettings);
load();
and finally save() and load() functions:
public function save():void
try {
log("begin save()");
var file:File = File.applicationStorageDirectory.resolvePath("settings.txt");
var stream:FileStream = new FileStream();
stream.open(file, FileMode.WRITE);
var settings:GameSettings = new GameSettings();
settings.fullId = fullId;
settings.mute = mute;
stream.writeObject(settings);
stream.close();
log("end save()");
catch (error:Error) {
log("[ERROR] " + error.name + ": " + error.message + "\n" + error.getStackTrace());
public function load():void
try {
log("begin load()");
var file:File = File.applicationStorageDirectory.resolvePath("settings.txt");
if(!file.exists){
log("settings.txt does not exist, created new one..");
save();
return;
var stream:FileStream = new FileStream();
stream.open(file, FileMode.READ);
var settings:GameSettings = stream.readObject() as GameSettings;
mute = settings.mute;
fullId = settings.fullId;
log("loaded mute = " + mute);
log("loaded fullId = " + fullId);
stream.close();
log("end load()");
catch (error:Error) {
log("[ERROR] " + error.name + ": " + error.message + "\n" + error.getStackTrace());
My GameSettings class:
package
public class GameSettings
public var fullId:String;
public var mute:Boolean;
public function GameSettings()
This works on desktop, android. Works on my ipad too, which has 10gb of free space. However, like I said, it doesn't work on iphone5s with 40mb free memory.
Here's a log:
begin load()
settings.txt does not exist, created new one..
[ERROR] Error: Error #0
at Autumn/save()
at Autumn/load()
at Autumn()
It's clear that AIR can't open or write to 'settings.txt' file. What can I do to solve that issue (other than making more free space on iphone)? Is there any workaround for that?Any help please?

why temp free space is different in both queries above..
which one is correct.....why temp free space is different in both queries above..Because you are looking at two different values.
V$SORT_SEGMENT gives details about the sort segment created in a temporary tablespace. The sort segment created may or may not be of the same size as the complete temporary tablespace. In your case, the sort segment has a total size of 568 MB but only 23 MB is being used.
V$TEMP_SPACE_HEADER refers to the physical files allocated to the temporary tablespace; so the other query is giving you the free bytes in those files. -

HT4137 No Free Space available to restore back up
My iphone 5 's power button stopped working and the battery was shot. I went to the apple store and they replaced it no questions asked. They told me to come home and restore from back up. Well, 2 hours later I'm still not restored. I keep getting an error saying iphone can't be restored from back up because no available free space. Can someone assist me in freeing up space?
Restore as new and sync back the desired content.
Just curious, did you confirm it was replaced with the same capacity device? -
After Yosemite Upgrade my Macbook shows incorrect free space available on Macintosh HD
Hey all .... after doing the Yosemite upgrade on my Mid 2010 15" MacBook Pro it finished but when I double click on the Macintosh HD it shows 140.62 TB available ... kinda impossible since I only have a 500GB drive inside the laptop ...
Methinks I found a bug ... not a huge deal as I know it's likely 140.62 GB free as opposed to TB ... just find it curious ...Hey - did you get anywhere with this?
I have the exact same problem and it is definitely related to iTunes Match (I enabled 24 hours ago and the problem started immediately).
In my case the actual phone displays the correct information (about 1.3gb free) but via iTunes (either connecting over wifi or over usb) it displays 19.4 gb free.
In my case the difference is almost exactly the size of my iTunes library.
Here is what I belive is happening (no fix yet).
I have enabled iTunes Match on my phone but I have left the song files on the phone (i.e. I play files actually from the device and not from the cloud) . Now, when I connect to iTunes, iTunes sees merely that iTunes Match is enabled and therefore belives that the phone does not contain any downloaded music (or at least did not contain any at the point iTunes Match was enabled) and therefore displays a library-size chunk as free space.
One fix which I suspect would work would be to delete my entire library from the iPhone, enable itunes Match and redownload the entire library from the phone. That however is not something I want to entertain at present.
This has to be a bug at Apple's end - I hope they fix it soon! -
Unable to install when 32GB free space available
LabVIEW 5.1 installer gave an error stating that my application could not be installed because there wasn't enough free disk space. The app requires ~50MB, there was > 32GB of free space on the C: drive.
You may also suggest using a 3rd party partitioner like Partition Magic, so it's a dynamic partition done through the OS, vs fdisk-ing it.
I'm not sure if this is a viable alternative, but you may want to see if just the LV 5.1 runtime engine installs w/o error, then build the vi's as an executable.
I'd try the standalone RT Engine, vs. doing it off the CD:

MBP unresponsive and zero free space available
Many people using this MB nobody cared to let me know we were running out of space. Today I was downloading a big file (1GB) when I got the "running out of space" alert message. Went to open info in the HD and saw there was only 255MB!!! I opened Trash but before I could hit "empty trash" the system froze. I can see there is "zero bytes" as available space... Nothing is responding, nneither the trackpad not the keyboard. SOS! I don't know what to do... It has been frozen for 1/2 an hour now..
What should I Do? MBP is running Mavericks.Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. -
How does repeated snapshot import impact tablespace free space?
Hello,
Our client is doing DEC-2014 reconciliation in FCM. Every time he changes profile mappings he has to do snapshot import again. So far he did at least ten times snapshot import for DEC-2014 period. In our FCM database Tablespace FCM_TX_TS_DATA free space is reduced 7 GB for this period already by querrying dba_free_space table.
By my understanding during the repeated snapshot import for the same period, the previous load data is deleted and the current load data is inserted. After data delete the table space will not be set free, and high water mark will not be reset.
During snapshot import will the deleted blocks from the previous load be reclaimed when new load data is inserted in the table? If not, what is the best way to reclaim the free space in FCM_TX_TS_DATA tablespace?
Thanks,

Hallo. I need to replace all schemas from one server to another. I want to know how much free space will be left on /data after this kind of refresh. Both servers are Oracle 9 so I will use exp/imp. Here is how I do it. Could you check if I think good? On target server there is 72 GB free space on /data.
Filesystem Size Used Avail Capacity Mounted
/dev/vgsmxdata/lvsmxcopy 194.74G 122.56G 72.18G 63% /data
Overall size of schemas to be exported from SOURCE_DB is 150 GB. The same schemas on TARGET_DB takes 90GB. So difference is 60GB. Free space in datafiles in TARGET_DB is 30GB. Does it mean that in first place the free space in datafiles will be filled and after that datafiles would be extended? That would mean that a database would extend to 150GB and free space on /data would be 40 GB after refresh. Am I right?

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

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.

SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_used,

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) descDBA_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
