• Question regarding tablespace TEMP and the o/s file associated with.

  Hello
  
  I want to write a simple query that returns the existing storage space and files that are part of each tablespace.
  
  I tried the script / query:
  

  col tablespace_name format a15
  col datafile_name   format a35
  col MB              format 999999
  col "CreateSize MB" format 999999
  
  --
  -- following two queries present only to show the problem I'm running into
  --
  
  select ts#
       , name
    from v$tablespace;
  
  select ts#
       , name
    from v$datafile;
  
  --
  -- this ALMOST works
  --
  
  select t.name tablespace_name
       , t.bigfile
       , d.name datafile_name
       , d.bytes/(1024*1024) MB
       , d.create_bytes/(1024 * 1024) "Create Size MB"
    from v$tablespace t
    join v$datafile   d
   using (ts#)
  ;

  The last query fails to display the files associated with it and the TEMP tablespace.
  
  Question: what tables should I ask to get a complete picture (one that is not lack of TEMP and its files)?
  
  Thank you for your help,
  
  John.

  V$ tempfile

  dba_temp_files

  Here you get a temporary tablespace.

• Question about Tablespace default temporary

  Hi, all.
  
  It is a "Newbie Question"
  
  If I execute the following SQL statement:
  
  SQL > select tablespace_name, content from dba_tablespaces, this is what I get + other tablespaces.
  
  NOM_TABLESPACE... CONTENT
  
  SYSTEM ....................................... PERMANENT
  TEMP .......................................... TEMPORARY
  
  My question is about the TEMP tablespace. What is the default permanent tablespace defined by the system? In OEM grid control, where it is explicitly stated that it was defined by the permanent system default storage space?
  
  How to know for sure if storage space is the temporary tablespace default or not, without run the drop command and get the following message:
  
  SQL > temp DROP TABLESPACE;
  Drop tablespace temp
  *
  ERROR on line 1:
  ORA-12906: cannot remove the temporary tablespace default
  
  
  Thank you!

• Question of tablespace group

  11.2.0.2 on Oracle Linux
  
  
  Default tablespace for the user SCOTT is MDS_TEMP tablespace. Tablespace MDS_TEMP is regularly full due to heavy sort.
  We have an another temporary tablespace called RTG_TEMP used by another user, which is less demanding in time and was usually about 20g of free space.
  
  
  We want to create a tablespace group "combining" MDS_TEMP and RTG_TEMP. But these storage spaces were not initially created with
  
  TABLESPACE GROUP mentioned in clause
  http://www.morganslibrary.org/reference/tbspgroup.html
  

  CREATE TEMPORARY TABLESPACE batchtemp TEMPFILE '/u02/oradata/temp04.dbf' SIZE 2G
  TABLESPACE GROUP temp_grp;

  Is there anyway that I can still do a group of these two storage spaces?

  alter tablespace mds_temp tablespace group temp_grp;
  alter tablespace rtg_temp tablespace group temp_grp;

  Select * from dba_tablespace_groups;

• Questioning Bigfile tablespace

  What will be the minimum size of a single data file for the creation of bigfile tablespace?

  John Stegeman wrote:
  Why do you need to know? As far as I remember, it's small enough (100 k or less)

  "cute" is correct, but I think it may be a little over a megabyte for the latest versions of Oracle - I think that Oracle reserving 1 MB for the mapping of file space recently, I noticed.

• EBS 12 - closer to the time it takes to merge of tablespace

  Good evening!

  Guys, I have detected a hint of fragmentation of 6.58 in a tablespace of our test EBS server.

  They asked me to try to recover the disk space, so initially I want to execute a statement "ALTER TABLESPACE COALESCE nom_tablespace" on this tablespace.

  This is the scenario:

  OS: RHEL 5.7 x86_64

  Oracle EBS: 12.1.3

  Oracle database: 11.1.0.7.0

  Processors: 8

  RAM: 16 GB

  The memory allocated to Oracle DB: 8GB

  Tablespace to coalesce.

  Total size: 384GB

  Used tablespace space: 372,9 GB

  Free space: 11.1 GB

  According to your own experience, how long could merge this tablespace? I have to communicate an approximate time of how long the process at the head of our Department before proceeding.

  Thanks in advance!

  Good afternoon!

  Sorry for the absence.

  I made a clone of our test EBS server and run the statement "ALTER TABLESPACE nom_tablespace COALESCE", surprisingly the process finished 5-7 seconds later.

  Then I read about this behavior, and the answer comes from the Oracle DB documentation:

  «Free coalescence extends is not necessary for locally managed tablespaces.»

  I questioned the tablespace, it is managed locally. So, for me, it was a good lesson.

  After this discovery, I proceeded to reorganize the storage space.

  Thanks for your advice!

• Many storage spaces and data for each quarter of the year files

  Hello

  I am junior DBA and I have a question about tablespace partitioning or data file sharing.

  I have a database of 10g in many storage spaces, for example:

  KER_DATA_2009_Q1

  KER_DATA_2009_Q2

  KER_DATA_2009_Q3

  KER_DATA_2009_Q4

  KER_INDX_2009_Q1

  KER_INDX_2009_Q2

  KER_INDX_2009_Q3

  KER_INDX_2009_Q4

  There is also a data file for each tablespace that is mentioned.

  But for this year 2013, only two big storage space I can get one and data KER_DATA, KER_INDX files.

  All tables and indexes in the whole database are KER_DATA, KER_INDX, tablespaces.

  I don't know any cut in two storage spaces and means of data files. Is this something like tablespace partitioning? This can be done automatically or someone needed to do it manually on the end of each quarter?

  This should be done to improve performance, several small files data instead a large?

  Can some admin explain this to me?

  The reason for this separation of database/tablespace was partitioning. There are a lot of tables partitioned by date column, and there are partitions for each quarter of the year. There are tablespace with a data file for each quarter (partition).

• Storage spaces.

  Hi all

  I use 11g R2 and I have a question about tablespaces / data files.

  I added a data file to one of my tablespace and asked me if the addition of a data file instead of increase the existing data file would no more framentation.

  For me as that as the tablespace is locally managed mode it will prevent framentation.

  What do you think?

  Thank you very much.

  Set the "fragmentation".

  For the kind of things that most people call 'fragmentation' (there are many different definitions), a managed tablespace locally is immune or practically insensible to the "fragmentation".  Thus, for most of the definitions, it is immaterial that you add an additional data file or increase the size of your existing data files.

• Max_size parameter in the dba_tablespaces

  Hi all
  
  
  I'm on environment of 11G oracle using SPARC machine.
  
  
  I created a tablespace yesterday with the following query:
  

  SQL> CREATE TABLESPACE XXXX_DATA LOGGING
    2      DATAFILE     '/XXXX/XXXX/f_data01.dbf'  SIZE 512M REUSE,
    3                   '/XXXX/XXXX/f_data02.dbf'  SIZE 512M REUSE,
    4                   '/XXXX/XXXX/f_data03.dbf'  SIZE 512M REUSE,
    5                   '/XXXX/XXXX/f_data04.dbf'  SIZE 512M REUSE
    6                    EXTENT MANAGEMENT LOCAL UNIFORM SIZE 10M;

  It was created, but with that I found a MAX_SIZE parameter value: 2147483645 when I questioned the tablespace using select * from dba_tablespaces where nom_tablespace = 'XXXX_DATA ';
  
  I did not specify this argument. Other tablespaces that exist have this parameter the value empty.
  
  What is the importance of this parameter. Is it possible altered, set empty?
  
  What happens if the size of the segment increase beyond this MAX_SIZE?
  
  I checked on google, and he told her:
  
  Maximum size of the max_size default NUMBER of segments.
  (http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/statviews_5054.htm).

  Hello

  Max_size defaults to the maximum size of the segments. the default size is unlimited.
  Max_size is new column the DBA_TABLESPACES in 11g.

  You can change it.

• Question about ALTER TABLESPACE add datafile on/slide

  Good afternoon
  
  As an exercise, I created a STORETABS tablespace and added a data file using the command:
  

  SQL> alter tablespace storetabs add datafile 'e:/storetabs3.dbf' size 50M;

  This successful step. A new file was created at the root of e: as expected.
  
  Following this command, I have published:
  

  SQL> alter tablespace storetabs drop datafile 'e:/storetabs3.dbf';
  
  Tablespace altered.

  The command succeeded. However, the file * ' e:/storetabs3.dbf' * has not been deleted. After re-reading the documentation found at http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3002.htm, I feel that deleting the operating system file itself is something that must still be done manually.
  
  Question: Am I right that there is no option to cause 'alter tablespace < tablespace > drop datafile < datafilename >' remove it the o/s file? In other words, should the o/s file always be deleted manually as a separate step?
  
  Thank you for your help,
  
  John.

  John,

  Don't know what part of the documentation page you are referring to but on the same page to the following location
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3002.htm#sthref5437,
  He clearly staes

  Specify DROP to drop from the tablespace an empty datafile or tempfile specified by filename or file_number.
  This clause causes the datafile or tempfile to be removed from the data dictionary and deleted from the operating system.
  The database must be open at the time this clause is specified
  

• Question of R11 and a tablespace

  Another issue is my APPS_UNDOTS1 tablespace datafile (these are the 3 files) are now 100%... Should I resize them or its unncessarry?
  
  Thanks for the tips

  Hello

  The quesiton is when we resize datafile? I mean when we say "oo the datafile is %? to help so I have to resize.

  There is no precise answer to this question, and it depends on how this tablespace is used and the size of the storage space (for example, 70% used space of 1 GB tablespace is different than 70% used space of 100 MB tablespace). So, I would say that whenever you think that you need to add more space to the tablespace (these data files).

  Another issue is my APPS_UNDOTS1 tablespace datafile (these are the 3 files) are now 100%... Should I resize them or its unncessarry?

  You have not to-see (Note: 413732.1 - Full UNDO Tablespace in 10gr 2) for more details.

  Kind regards
