Should I create bigfile tablespace?

• What consideration we should have have before creating the tablespace

  Hello
  I was asked this question in an interview. I have a large volume of data (for example 80 GB). Now, I have to create a tablespace to contain these data. What consideration we should have have before creating the tablespace.
  In fact, I could not answer after a lot of research, so I post here.
  
  Concerning

  Hello

  In 10g, you must create a locally managed Tablespace (MEASURE of the LOCAL MANAGEMENT) If you know the
  size of your Tables/indexes you can choose the size of the scale with the option of UNIFORM SIZE.
  If you have small and large Tables / Index, then choose the AUTOALLOCATE option.

  It is recommended to use SAMS with the SEGMENT SPACE MANAGEMENT AUTO option and then the PCTUSED
  is auto tune by an internal algorithm and FREELIST are managed by a bitmap. With this option, it is best to
  be with the last group of hotfixes.

  About BIGFILE Tablespace, if you use BIGFILE tablespace, you will have just a data file which can extend up to
  4G block (thus 32 TB if you have db_block_size = 8KB). And SQL syntax allow you to manage the 'big' with data file
  the same command for the Tablespace.

  But you should care the limit of your OS. Imagine that your operating system or the file system does not support very largefiles then,
  you have no advantage over the use of Bigfile tablespace. Also, you might have more than 1 data file.

  Smallfile Tablespace using your data files should not exceed 4M block (so 32 GB for 8 KB / block) but you can have
  up to 1022 datafiles on your Tablespace. So eventually, if you use the 1022 data files, you have the same capacity
  Bigfile Tablespace and you can use several system files.

  To 80 GB with 3 or 4 data files, you can easily manage this volume. But of course from time to time you will have to
  Add a new data file.

  Hope this can help.

• 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

• 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.

• Creating table: Tablespace determination?

  If you do not specify a tablespace that he will enter the default tablespace that is associated with the user.

  You can also specify that the table space table set in the CREATE TABLE statement.

• Should I create pagefile on ramdisk with my new SSD?

  Hello

  Got my new SSD which is the only drive in my system now. To avoid the heavy writing on this drive, I bought Superspeed Ramdisk more (IE temporary files etc.). I have Windows Vista Business 32-bit with 4 GB of ram. The Ramdisk software is able to use the ram 512-1024 that Vista cannot use. In addition, this software can serialize the contents of ramdisk so that it IS possible to run the file here.

  I only use this portable desktop so I'm never near max on virtual memory.

  So, should I create my swap file on a virtual disk? And if so, it would be enough with 512 MB pagefile? Vista will allow me to set this parameter or create the pagefile on my boot drive, regardless of my settings?

  EDIT: Just for clarification and the difference of this thread and 1000 others, my concern here is the constant of writing in the pagefile on my SSD. Not the small gain (if any) the pagefile in Ram would produce...

  --

  SSD? Nice.

  I try and run the pagefile from the Ramdisk to be tested, according to your needs, you may have to go to the EHR.  However, you should have the system handle it anyway.  You can change it, but for now, since the system is new with lots of RAM, test how the virtual disk swap file works if this does not work for you.  You can still use the standard configuration with the swap file managed by the system on the disk.

  Unfortunately I am not too familiar with the Ramdisk software and good course:

• My question is: is there an approach appropriate to where and how files should be created and arranged, except directly in your main drive, in my case C:?

  I recently had a hard drive replaced requiring a new installation of Windows 7. When I went to get the system in place, the guy who set up Windows told me that he created the user directory specifically in a way so that new files to be created in a Documents folder that was created under the username. At least that's what, in my view, said.

  In any case, I always create new folders and their subfolders under Local C: drive.  My question is: is there an approach appropriate to where and how files should be created and arranged, except directly in your main drive, in my case C:? Thank you for your help.

  Windows 7 has been designed with the intention that user folders and files will be store in one of the folders under the users, that is to say the Documents, photos, etc.

  It is not recommended to store in the root, i.e. C:\ directory.

  If you have any other disks or partitions, you can store what you want there.

• where should I create file?

  Hello

  my application must create a file at the beginning. I am way wondering - which should I use to create a file? No each device has a memory card. y at - it smth like 'C', for example:

  _fc = (FileConnection)
  Connector.Open ("C:\" + _fileName, Connector.READ_WRITE);

  or where should I create TI-so that it won't be a problem on any device?

  Kind regards

  You can check by program if the external memory (SDCard) device.

  http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1295814/How_To...

  If the device is not external memory, you can save your file in the internal memory.

  In this case, make sure that the device has available for saving this file space. You will get this information from class MemoryStats.

  To save the file in SDCard use something like:

  FileConnection fc = (FileConnection) Connector.open(System.getProperty("file:///SDCard/"+"fileName.txt"),Connector.READ_WRITE);
  
  if(!fc.exists()){  fc.create();}OutputStream os =fc.openOutputStream();os.write("Test");os.close(); fc.close()
  

  Also check this link for more information on the file path.

• Can u create a tablespace with these settings?

  I use 12.1 DB. I need to create a tablespace with 1 data file (say abc.dbf), initial size is 10 MB, but I need grow no more than 1 GB.

  I tried the user guide. You can give the initial size of the DB using SIZE 10 M, but I couldn't find a way to give an upper limit for the tablespace.

  There are 2 settings in the DBA_TABLESPACES view.

  Maximum default MAX_EXTENTS NUMBER of extensions

  Maximum default size of max_size NUMBER of segments (in Oracle block)

  There is no clause in measure Network Management of the TABLESPACE CREATE & segment management of the sous-clauses to give a maximum number.

  Is how Oracle works is like, if you create a tablespace with a data file of 1 G, with autoextend NO, then it will grow to 1 G and then stops?

  If so, what did MAX_EXTENTS & MAX_SIZE really means?

  The physical limitations of the database for 12 c gives this information:

  Blocks of database

  Maximum per data file

  Load platform; generally 222 - 1 blocks

  So, if my block size is 8 k, then the maximum size for the data file is just 8192) /(1024*1024*1024) ((2^22-1) * = 32 GB, which is very low for a single file of data?)

  SQL > create tablespace foo

  2 datafile 'c:\temp\foo.dbf' size 10 m autoextend on maxsize 1 g;

  Created tablespace.

  Yes, are.

• Audit trail Tables should be in SAMS tablespaces in 9i / 10g?

  Hello
  
  I know that a strong recommendation for 11g is that we house the SYS. AUD$ and SYS. FGA_LOG$ table in a tablespace SAMS and certainly NOT the system tablespace.
  
  However, I am struggling to find anywhere where it says the same for previous versions of the database - specific 9i and 10g.
  
  I thought I had read somewhere that Oracle do not support move the tables out of the SYSTEM tables audit trail in previous versions, but I can't find where I read that.
  
  Basically, I presume I can create a tablespace of VERIFICATION that uses the SAMS and move the tables on 9i / 10g? (Yes, I know things being out-of-support - application vendor has not yet certified 11 g!)
  
  Mark

  Erman Arslan says:
  Yes... interesting... maybe he can perform certain operations such as upgrade version and that is why it s not supported...

  But knowing how do has been public knowledge for several versions and is very common. I have been at this since 7.3 and have never heard a question resulting from travel sys.aud$ and he associated with the index another tablespace. And that's really it, that is. If you look at the script "unsupported" provided by oracle, you will set it's just move a table and rebuild its indexes. No tricks Super hidden guru.

  The question is not SAMS vs non-SAMS. It is a very volatile table of the TS system.

• 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.
