Questioning Bigfile tablespace

Similar Questions

• Bigfile tablespace for the system tablespace.

  I am trying to create a database with bigfile tablespace for the SYSTEM tablespace as well. Can I use dbca to create and define bigfile tablespace for the SYSTEM tablespace.

  How can I create system with the CREATE DATABASE statement bigfile tablespace?  Can be a help for syntax?

  Even if the normal tablespace is sufficient for the system, I just wanted to check if there is a syntax to create.

  Thank you

• Should I create bigfile tablespace?

  Hello

  I need to move a database from the old server again.

  Old server: Oracle 11 g 2 (11.2.0.3.6) on the file system - on OEL 6.2 64bits

  New server: Oracle 11 g 2 (11.2.0.3.6) on ASM - OEL 6.2 64bits

  All areas of storage in this database are small and simple datafile except one. Here are the DDL:

  CREATE TABLESPACE DATAFILE DATA1

  ' / u1/oradata/PRD/data1_01.dbf' SIZE 25 G AUTOEXTEND OFF;

  ' / u2/oradata/PRD/data1_02.dbf' SIZE 30 G AUTOEXTEND OFF;

  ' / u9/oradata/PRD/data1_03.dbf' SIZE 30 G AUTOEXTEND OFF;

  ' / u3/oradata/PRD/data1_04.dbf' SIZE 30 G AUTOEXTEND OFF;

  ' / u5/oradata/PRD/data1_06.dbf' SIZE 1 G MAXSIZE AUTOEXTEND ON NEXT 8 K 30 G,.

  ' / u6/oradata/PRD/data1_05.dbf' SIZE 6124 M AUTOEXTEND ON NEXT 100 M MAXSIZE 30 G

  LOGGING

  ONLINE

  EXTENT MANAGEMENT LOCAL AUTOALLOCATE

  8K BLOCKSIZE

  SEGMENT SPACE MANAGEMENT AUTO

  FLASHBACK ON;

  I wonder if this will be an advantage (performance wise) if I create a BIGFILE tablespace instead of several small files as above?

  Please advise!

  Hello

  There is a gain of performance on startup, control points and operations of DBWR bigfile tablespaces in more traditional (petit_fichier) spaces of storage.

  Yes, are.

  Not sure about your body, but you can run this query and see if you have any bigfiles.

• BIGFILE tablespace

  Hi all
  
  
  Can someone explain please HOW BIGFILE TABLESPACE is works, if all OS supported (32-bit servers)? is there a limitation?

  Hello

  A BIGFILE Tablespace has only 1 data files that can (in theory) to reach a size of 4 Gblock. Thus, for example, if the "db_block_size' of your database is 8K, then the data file could reach only 32 TB.

  Of course, it must be supported by your operating system. If your operating system has a lower limit for the file size, you will never have such a big Datafile. And, in this case, you have no advantage to using BIGFILE Tablespace.

  Please find attached a link to BIGFILE Tablespace:

  http://download.Oracle.com/docs/CD/E11882_01/server.112/e10595/tspaces002.htm#i1010733

  Hope this helps.

• Migration to a bigfile tablespace

  I have a table that is all set up and populated. Is there a way to create a table based on the properties of another table but as bigfile instead of petit_fichier? I found that you just can't convert the petit_fichier bigfile but have failed to find any documentation on how to go on the migration to a bigfile tablespace. Again, any help is appreciated, I'm new but with oracle much thanks to find this forum.

  'bigfile' is a property of the storage space, not the table. Just create a tablespace 'bigfile' and move your table top.

  You may not think that there is a one-to-one relationship between tables and tablespaces are you? A table lives in a tablespace, but a tablespace can contain several tables. And any relationship between the storage spaces and patterns/users is strictly your own agreement to facilitate the administration. There is nothing in Oracle, which makes this link.

• 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

  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

  Hi all

  I am trying to insert data into a table in another schema

  insert into the table table_name select * from .table_name < another_schema > and get the error as

  Impossible to extend the table of 128 in tablespace < nom_tablespace >

  the size of the source table is 700 MB and I have 3.5 GB of free space in the tablespace where im creating.

  Not sure get this eventhough I have space in the tablespace

  Please let me know what I should check

  Regars,

  Hi Hemant,

  The table in the source schema is not compressed.

  No im using the normal insert as an insert statement in the table_name table don't select * from other_schema.table_name.

  But now the problem is solved.

  Here's what I did.

  I found in which data file structure of the object has been created and found it was created by datafile1.

  changed the datafile1 with autoextend on option and I was able to insert the data without any problem.

  Thanks much :-)

• 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;

• Question of Tablespace Temp datafile.

  Hi Oracle gurus,
  
  the problem occurred when my file temp01.dbf to increase the size of certain MBs to 30 GB! (Within weeks)
  without doing RnD on advice, datafile temp01.dbf has been deleted! ,
  now a text file has been created, I renamed it with the same name 'temp01.dbf '!
  
  now my tasks fail with the error:

  ORA-01110: data file 201: ' C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\TEMP01. DBF'

  1. connect to sqlplus DBA (user sys)
  2. stop; -Removed database and Oracle Instance will stop.
  3. start; -Oracle instance started.
  4 run this query
  alter tablespace temp add datafile
  ' C:\oracle\product\10.2.0\oradata\orcl\TEMP02. DBF' SIZE 32 M;
  
  but still the error points to Temp01.
  
  The funny part, I wrote here that I don't get the name of the data file anywhere in the comic book.
  
  I've run this query below
  
  SELECT FILE_NAME IN DBA_DATA_FILES;
  
  and there is no name of data file with "Temp01" or "Temp02".
  
  I get the name 'TEMP' Tablespace when performing "SELECT TABLESPACE_NAME FROM DBA_TABLESPACES";
  
  to add more of what the above
  
  I tried to delete the file with the name 'TEMP01. DBF. "
  by running
  
  alter tablespace temp drop datafile
  ' C:\oracle\product\10.2.0\oradata\orcl\TEMP01. DBF';
  
  I get the following error:

  2 allow the name of auto extension datafile renamed as well as default data temp file features.

• Tablespaces temporary bigfile

  In most CCR environments, you use multiple tempfiles in a tablespace temp to avoid conflicts in the OLTP Exadata recommended he guides his stats you should start by using a for temporarty tablespaces bigfile tablespace. It seemed strange to me since bigfile tablespaces can have only a temporary file. Understand that OLTP have no parallelism, so multiple tempfiles may not be necessary, but he seemed always strange to use bigfile instead of petit_fichier tablespaces for something like temp. Does anyone have experience with the help of tablespaces bigfile RAC for temporary tablespaces.

  I used bigfile temporary tablespaces for some operations intensively parallelized and never met with contention problems. If I were you, since we are talking about temporary things, I do change and run tests.
