determine the free space of the tablespace

Hi all

How to determine free space of the tablespace?

Can use this:

select tablespace_name,
case when sum(bytes) >= 1073741824 then round(sum(bytes)/1073741824,2)||'gb'
     when sum(bytes) >=1048576     then round(sum(bytes)/1048576,2)||'mb'
     when sum(bytes) >=1024        then round(sum(bytes)/1024,2)||'kb'
     else sum(bytes)||'bytes'
end free_space
from
(select tablespace_name, bytes from dba_free_space
 union all
 select TABLESPACE_NAME, 0 from dba_tablespaces where CONTENTS != 'TEMPORARY' -- this will add full tablespaces
 union all
select tablespace_name, maxbytes-bytes
 from dba_data_files where AUTOEXTENSIBLE='YES' and maxbytes>bytes)
group by tablespace_name order by sum(bytes);

  • to know the amount of free space in a tablespace

    Hello

    I'm learning to oracle 9i release 9.2.0.1.0. I had created a tablespace 'TOOLS' to use the default tablespace for Statspack.
    I would like to know the amount of free space available in this table space. To do this, I ran the following query, but there was no selected lines:-

    SQL > select tablespace_name, bytes from dba_free_space
    2 where nom_tablespace = 'TOOLS. '

    no selected line

    SQL > select name from v$ tablespace;

    NAME

    EXAMPLE OF
    INDX
    ODM
    SYSTEM
    TOOLS
    UNDOTBS1
    USERS
    XDB
    TEMP

    Can someone say the reason for this.

    Strange that the difference of 0.625 MB does not appear in free_space...
    But anyway, this tablespace is good as COMPLETE.

  • ORA-01659: impossible to allocate MINEXTENTS beyond 2 in the tablespace test

    Hello

    I created a table and tried to insert records over 2 million and I'm getting an error such as ORA-01659: impossible to allocate MINEXTENTS beyond 2 in the tablespace test.

    Used tablespace percentage is only 73%.

    I used below when creating table

    tablespace TEST

    PCTFREE 10

    Please suggest me how to solve this problem.

    Hi @Suri

    I see no problem in storage settings in your table.

    But the number of rows helps you insert and in the free space in your tablespace.

    Perhaps too much space is needed for your data and storage space can not support.

    The only things you can do is the following:

    (a) try PCT_INCREASE to 0, this product extensions to equal size.

    (b) put the PCT_FREE less than the default of 10. But it is advisable if you make updates to your table.

    (c) maybe create your table with the clause compress, just for bulk inserts, but this depends on the use of the table.

    (d) ask your DBA to increase the data files of the TEST table space or add more data files.

    (e) using the package DBMS_SPACE, you can calculate the space used by your table in tablespace TEST. g 10 and later versions.

    See the following example:

  • No way of knowing where the tablespace used for a period of time

    Hi all

    I have a very generic question:

    We have a daily report for information storage space in our production approx. In a 30.97% of free space in a tablespace on 27/06/2009. 28/06/2009 it reported only a 1.53% free. I would like to know what segments of the entire space went during this period. I looked in the dba_extents but could not see at all times by related information, which tells me that when the extents allocated. Anyone can share this info with me?

    Thanks a lot for your help in advance!

    Shirley

    _DELTA usually indicates a change (i.e. the size has changed during the snapshot interval).

  • How to find space in a Tablespace?

    Hello

    I have limited access to the objects in my database (do not have access to several tables).

    I have 300 GB in size in my table space that allows me to create my objects.

    Now, I want to know how much this size of table space allotted to me have exhausted. I don't have access to dba_data_files and dba_segments.

    Is there a way out for me? Could someone show me a way please?

    This query will give you the necessary information, but it uses DBA tables.

    SELECT B.TABLESPACE_NAME, TBS_SIZE SIZEGB, A.FREE_SPACE FREEGB

    from (select nom_tablespace, round (sum (bytes) / 1024/1024/1024, 2) as free_space)

    from dba_free_space

    GROUP BY TABLESPACE_NAME),

    (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 the details of your tablespace then the above query can be modified to get the free space in your tablespace. Now I use user_frees_space and not dba_free_space. In general the user tables are and must be accessible to users.

    Select nom_tablespace, round (sum (bytes) / 1024/1024/1024, 2) as free_space

    of user_free_space

    where nom_tablespace = "your name of the tablespace.

    GROUP BY TABLESPACE_NAME;

    If the column "MaxFree (M)" you show no space required, then your data files are not configured well. Your DBA must configure the parameters 'CanGrow' and 'maxsize' adequate level data file in each tablespace.

  • Is it difficult for oracle follow the news of free space in the tablespace Temp?

    DB version: 11.1

    I know that temporary tablespace is 'temporary' and varies according to gender, creating index... etc. But, can't they say just free space in bytes.
    Lets say my temporary tablespace size is 2 GB and if the DBA_TEMP_FREE_SPACE.free_space column is 500 MB. What does that mean?

    This means for a locally managed temporary tablespace, reduce the size to the amount of space currently in use; in other words, reclaim the space unallocated and allocated space is unused.

    TABLESPACE_SIZE - FREE_SPACE

    The great sorting operations performed by the database can cause a temporary tablespace more and taking a considerable amount of disk space. When the sort operation is complete, the extra space is not released; It is just marked as free and available for reuse. Therefore, a single operation of large size can result in a large amount of temporary space that remains unused, once the sort operation. For this reason, the database allows to shrink the locally managed temporary tablespaces and free up unused space.

    Shrinking frees as much space as possible while maintaining the other attributes of the tablespace or tempfile.

  • How to free space on the hard drive?

    Hello, in my "On Mac" section, it says I 233 MB of space on my 121 GB of Flash storage. Previously, I thought it was video files, but it was buggy mac section. I refreshed, hoping he would show me how much space I had left, but he stayed the same. That is the problem. I use my macbook for College written work and - maximum - work on Adobe Creative Suite. When I work on these I use a separate USB key due to the size of the files.

    The only files I have actively created/downloaded on my macbook are the files in the files of my 'Documents', 'Pictures' and 'Applications '. When I use "Get Info" on each, I see that my photo folder is great, My Documents folder is large 1.17 GB and my Applications folder is large 14,68 GB 889,9 MB. These are the only files that I use and backup the files needed for my Macbook running and working properly, the only files I want to keep.

    My question is, basically, if there is a way to lose all the files on my hard drive that are not necessary to keep. I'm not too good when it comes to computers, so I don't want to not just randomly start deleting things. Just to get these road, my garbage can is completely empty and I have nothing in my downloads folder. I have also no large files to film and, when I searched my Macintosh HD for files larger than 500 MB, there is no evidence, so I guess that this is caused by a large amount of small files (I tried to restrict research naturally but then come files that I wasn't sure of what they have done and therefore have not removed the still). If it helps, my about Mac filed 100,64 GB of my free space as 'other '. But I know that is not how much space was taken when I got the Macbook earlier this year and it should not be the size of the files that comes with it by default. There is also a way to restore all the files on my macbook at their stage of default, that I would also be interested, especially if there is a way to do it without rid of files I already have.

    I guess that's a very basic question, can someone help out me?

    1. never remove all the files that you do not understand the purpose. If you do, it's like opening the hood of your car and take bits out of the engine ebcause you think they are not necessary.

    2. it seems more likely that you must rebuild your Spotlight index.

    See the following page:

  • What is the free space in Vista variant of +/-50 GB?

    Last night when I went to bed my system reported that I had 60 GB free. This afternoon, he pointed out that I have more than 111 GB of free. I have not emptied the trash, run Disk Cleanup, installed updates (it is set to "notify me but do not install" after this update in the fall of 2009, which made me unable to get on the internet) or anything that could justify such a wide gap.
    Accustomed to the amount of free space fluctuating by the swap file systems, I'm my system has only 6 GB RAM and what I have observed, I rarely fully used that. I expect a variance of + / 12 GB or more, not 50 GB.

    Is it normal for Vista 64-bit home premium with AVG free or is something current weird that I should try to trace? I only noticed because I knew I had to free 20 GB (probably more like 30-40) for a 580 GB partition on a drive of 500 GB of images and was preparing to move some installers downloaded from CDs and DVDs.

    To study disk space, use download and install Treesize (freeware).

    Information about Treesize

    http://www.Jam-software.com/treesize_free/

    When you open Treesize scan select in the Menu and you will see a list of drives. Click on C and it will generate a list of files. Display names and 6 larger files sizes and the total at the top of the list.

    To reconcile Treesize figures with the size of a partition (or drive), you must make allowances according to this formula:
    Partition C + folder System Volume Information + Free space + file compression gain = ability to drive or partition

    To determine the size of the System Volume Information folder, select Start, Control Panel, system, System Protection, click Configure under Protection settings. What is the figure of the current use?

  • determine the storage space for the upgrade of the APEX

    I put on my 11.2.0.3.12 level APEX APEX to APEX 4.2.4.00.08 version 3.2.1.00.12 version database.  I understand that I must perform the full upgrade, I am moving from version 3.2.x to 4.2.x.

    According to the APEX 4.2 Installation Guide for the full development environment, I have to spend in the following arguments:

    @apexins.sql tablespace_apex tablespace_files tablespace_temp images

    Where:

    • tablespace_apexis the name of the storage space for the user of the Oracle Application Express application.
    • tablespace_filesis the name of the storage space for the user to Oracle Application Express files.
    • tablespace_tempis the name of the temporary tablespace and tablespace group.
    • imagesis the virtual directory for the images of Oracle Application Express. To support future upgrades Oracle Application Express, set the directory of the virtual image that /i/ .


    How can I determine which user is the " " " User of the oracle Application Express application" and which the user is the user Oracle Application Express 'files' (if I can then watch their default storage spaces)?

    How can I determine which user is the user Oracle Application Express 'application' and that the user is the user Oracle Application Express 'files' (so I can then look at their default storage spaces)?

    APEX 3.2.x installation that follows is users:

    • Oracle Application Express Application user: APEX_030200
    • Oracle Application Express user files: FLOW_FILES

    So to determine the tablespace_apex and the tablespace_files you must connect with the user sys with sysdba privilege and run the following query:

    SELECT USERNAME
     , DEFAULT_TABLESPACE
  FROM DBA_USERS
 WHERE USERNAME IN ('FLOWS_FILES','APEX_030200')

    Then use the APEX_030200 user as tablespace_apex tablespace and a tablespace of the FLOW_FILES user as tablespace_files.

    I hope this helps!

  • Remove the constraint of PK to win space on INDEX tablespace

    I dropped a huge table (which has recently imported for testing) INDEX by deleting the PK constraint to win space on INDEX tablespace. But INDEX tablespace is not reduced image.

    Please notify.

    Kind regards

    Veera

    The tablespace not to shrink because it's a performance inhibitor.

    However, you can see the free space within the increase of tablespace, and this space is generally available for other objects.

  • Free space on the virtual?

    I'm having a moment.

    I'm under ESXi 4.1. I have a virtual named 'ISOs' which is where I put my ISO of Windows files. How can I determine how much free space I have in this virtual for more ISO? I might add to the top of the size of the files manually, of course.

    What confuses me is that in the client software under summary for this virtual I see 80.25 gigabytes of storage allocated and used 80 GB storage. My ISO something near that don't take much place. Where is the quick way to see how much actual physical space is available so that I can know how much over 3 gig ISO I can put in this store?

    Thank you.

    Mike Gallery

    When you are in the folder, you can select the iso file and it displays the size on the lower left hand side. However, it will not display the size of the content in the nested folders.

    /

    ISO

    Folder1

    Folder2

    ISO1

    ISO2

    IF you select all the content under the ISO, it will display the size of the ISO1 and ISO2.

    select file_name, bytes/(1024*1024*1024), autoextensiable, maxsize/(1024*1024)  from dba_data_files where tablespace_name='SALES_DETAIL_TS_IDX' ;

    find the data file that is not reached the maximum size (32GB if its 8 k block) and resize it to match your needs.

    alter database datafile '' resize ;

    Otherwise, you can add the new data file. Blow is the simple add datafile statement:

    alter tbalespace add datafile '' size ;

  • Calculation of the free space in a data file

    Hello

    I use Oracle database 11g (11.1.0.6). I need to calculate available disk space that exist in a special database for inserting new records. I look in the table dba_data_files for this information. I use the sub query to get the value of maxsize allocated in GB this until datafile that it can grow.

    Select maxbytes/1024/1024/1024 of dba_data_files where nom_tablespace = 'XXXX '.

    How to get the disk space available for the insertion of new records in a particular data file or a bunch of data files in a tablespace?


    Kind regards

    Kind regards

    007

    Use

    select sum(bytes/1024/1024/1024) GB from dba_free_space where tablespace_name='tablespace name'

    Know schemae storage space

    select default_tablespace from dba_users where username='schema name';

    Know the perticular table tablespace

    select TABLESPACE_NAME from dba_tables where table_name='table name';

    Utimetly you will be insert in tablespace, little matter how many data file you have and how many girl and how many of them have the space available.
    So just to worry when the table space is saturated.

  • Free space in the data store is lower we shouldn't

    Hello

    I'm under VMware ESXi on HP Proliant DL380 G5 server - the data store has a global capacity of 678 GB, with now 34 GB free. I have 5 VMs running:

    reader1/lecteur2

    (1) Win2k3: 50 / 100

    (3) Win2k3: 50 / 50

    (1) Windows XP: 10

    Oh - and the two models, one for the server (50) and a XP (10)

    Yesterday, I created a couple of clones of the XP, 1 with Vmkfstools - i and the other with vConverter - especially for the practice, but they are only 10 GB. Before my creations, free space read about 115 GB - then she got at the moment, I noticed 34GB. I deleted the two new virtual machines thinking I came home back from space, but no dice. Math is not my best subject, but this does not seem to add up. Do something wrong, I missed something?

    Is it possible to reclaim that space? Before I thought to check with you guys, it dawned on me that I could stop all VMs and restart the host, but if there is another way, I want to know it.

    Linda

    Browse the data store - go to the "Home" view - inventory - data warehouses, click a data store, and then select Browse.

    Look in the subdirectory for each virtual computer and determine that seem abnormal large size files and total size of all files that exceed the size of the virtual disks assigned to the virtual machine.  If you specify then what are the names of the files a plan for how to get rid of them.
