• Adjusting the size of a tablespace before its creation

  Hi guys,.
  
  Oracle version: 10.2.0.x
  OS: 32-bit Windows
  
  I was wondering if there are "conditions" by setting the intial size of a tablespace before its creation. This is because one of our clients wants to export and import one schema in another, but set an initial size for a tablespace when it is created and before you import the data into it, but we have a tool wizard database that creates patterns accounts using the sql underlying following: -.
  
  DataFile RIDGE TABLESPACE < tbl_name > < path > < datafile_name > .dbf SIZE 100 M AUTOEXTEND ON NEXT 100 M MAXSIZE 32000 M by DEFAULT of STORAGE (INITIAL 256 256 NEXT K MINEXTENTS 1 MAXEXTENTS PCTINCREASE UNLIMITED 0) ONLINE.
  
  Under normal circumstances, what he would do is to use our Wizard and create an account and then import data from a dump for export.
  But he wants to create a tablespace by using a SQL something like: -.
  
  DataFile RIDGE TABLESPACE < tbl_name > < path > < datafile_name > .dbf SIZE 2000 M AUTOEXTEND ON NEXT 500 M MAXSIZE 32000 M of STORAGE by DEFAULT (INITIAL 256 256 NEXT K MINEXTENTS 1 MAXEXTENTS PCTINCREASE UNLIMITED 0) ONLINE.
  
  
  It think it should be ok because his dump of export would be 2GB size and would like to import all that "both" i.e. without actually using characteristic autoextend for the first 2 GB.
  
  What's a sense? Guys do you see a difference "performance" between the 2 create tablespace statements?
  
  I think that the second sql (with size initially 2000M) seems to be a more logical approach, but I'm not really sure the implications towards the bottom of the line performance.
  
  Any help/input much appreciated!
  
  Thank you guys

  Hello

  Number of things,

  If your export dump is that 2 GB is not when the import is completed, it would take only 2G, it is possible it will take more space to do the import as some objects as index occupies no space in the dump file, but they do it in the database.
  If I know that my tablespace would 2G because of this activity I create tablespace with 2 G or manually increase it 2 G instead of auto expand because performance wise spatial distribution (with autoextend on) when running would take time.

  My database is the system of the PLO.
  
  My question is what are the advantages and disadvantages of having a single tablespace against several tablespace?
  
  
  Easy to maintain when you have only tablespace. but hard to follow questions of IO.
  
  Any other entry? Please let me know.

  Finally:

  It is good to have more tablesapce than a big tablespace.
  Above mention, big tablespace (all applications work according to this tablespace) so corrupted it will cause offline ask and time restore will take more time.
  It is easy to restore single tablespace (more than a big tablespace) example you gave, apt, Arch., idx, corrupt aud tablespaces, and if one of them is East use rman or managed user restore-restore. Other words, if not all, you mentioned tablespace that you will be asked time and so on.

• locally managed tablespace and confused fragmentation

  Hello
  
  I understand that its impossible to have a locally managed tablespace fragmentation, but when I run the following query I get
  

  select
  tablespace_name,
  COUNT(*) cnt_free_chunk,
  decode( round((max(BYTES) / 1024),2), 
  null,0, round((max(BYTES) / 1024),2)) largest_chunk
  from dba_free_space
  group by tablespace_name
  order by 2 desc ,1
  
  TABLESPACE_NAME                CNT_FREE_CHUNK              LARGEST_CHUNK
  ------------------------------              --------------                         -------------
  USR_IDX_TBS                         1739                               2359296

  The tablespace shows it was not plugged and uses LMT with SAMS.

  user9243284, you should not assimilate several free extensions as meaing the free space is fragmented even for dictionary managed tablespaces, much less for those locally managed.

  Really, what determines if the tablespace freespace is fragmented, it's if the available free space can be used or not when objects extend. You must map the extents of tablespace to get a better idea if the number of extensions of the free space indicates a problem could exist.

  In the case of a tablespace locally managed with uniform extents, free space fragmentation is impossible, because never available to what extent is the same size for each request for space is satisfied until there is no free extensions.

  However when-auto-assignment is a range of sizes of measurement are used where each larger size is a multiple of the previous size, which reduces the changes of Oracle is not able to respond to a request for free measure; However, contrary to belief the automatic assignment method does not eliminate completely the free space fragmentation.

  It is always possible to have a request for lack of space automatic sub-allotment when the total free space exceeds the amount of space requested. This can occur in two situations:

  First of all, the tablespace has been converted into place of dictionary to locally managed. Existing objects are not affected by the conversion so any existence before the conversion disorder still exists after the conversion.

  Second, where there are a few large objects stored with many small objects and the tablespace data files are either fixed in size max extended nearby, then it is possible to have a request for an extension of the free fail even if the total free space is greater than the measure requested. Say you want to 8 M and the tablespace has 40 M free. It may be that none of the extents are contiguous, if the request fails. Now, with a request for 64 M, Oracle will resign the next size measure and use up to 120 degrees of 8 M but more small scale application size are not not resigned in size (at least from my last test).

  I had this happen with a product of the vendor who provides the user the ability to create work tables and add indexes via the application. I love the uniform measure for this reason tablespaces.

• create the table with the parameters of storage in a locally managed tablespace

  Can we create object with the parameters of storage in a locally managed tablespace.

  default tablespace users is successful locallly.
  Then extended this table management will be managed according to the tablespace or storage settings which
  has been specified when the table was created.

  Hello

  This means that we don't have to define NEXT, PCTINCREASE, MAXEXTENTS at the object level.
  Then, these settings are applicable to Dictionary managed tablespace or what?

  Yes that's right, understand you is correct

  Can we define NEXT, PCTINCREASE, MAXEXTENTS at the level of the object in the dictionary managed tablespace;

  Yes, you can, but go for DMT, is not very good, because you advantages compared to LMT, just think about it before going to the DMT, than I suggest.

• Migrate from Dictionary Managed Tablespace locally managed - 10g

  Is there a document that indicates best practices to migrate the management measure dictionary managed tablespace to locally managed with automatic segment management space.
  
  I read that we can migrate using the DBMS_SPACE_ADMIN. TABLESPACE_MIGRATE_TO_LOCAL Procedure, but is not very clean because existing data will still use the managed dictionary and new lines inserted will follow the local space management, is this correct?
  
  Can someone please provide comments?
  
  Thank you
  KeV

  Kevin, my personal opinion is that future space management will be much easier for the DBA if the ADMINISTRATOR creates new tablespace by using local management instead converts the tablespaces in place. When the packaged DBMS_SPACE_ADMIN. Procedure TABLESPACE_MIGRATE_TO_LOCAL serves the existing objects are not resized and parameters such pctincrease are still in force. Convert the tablespaces bring their problem of fragmentation of space with them.

  New start. Also if you want to use SAMS you put on when creating tablepsace so new is necessary in this case. ALTER table move and alter index rebuild are an easy way to move most tables/index to the new tablespace. The old exp/imp can be used for objects with long columns.

  I saw the free space fragmentation problems in a tablespace which was not converted-allocation automatic. The use of auto-allocate will considerably reduce the likliness of a problem free space fragmentation, but in some cases, you may still experience the problem.

• Create locally managed Tablespace

  Hello
  
  Is it possible to create a new locally managed Tablespace in Oracle Database 10 g when the SYSTEM tablespace is managed DICTIONARY.
  
  Thank you.

  Yes, which was always possible since 8i, when SYSTEM could only be DMT but other storage space could be LMT.

  However, you cannot create a tablespace DMT if SYSTEM LMT.

  Management of the space will be much more effective if you use uniform extensions and specify a reasonable size for autoextend:

   next 1g uniform size 512k

  I should have added, what is your db_block_size? If the default 8 k, your maximum file size is of 32G.

• Use of a single tablespace or backup data file

  Hello
  
  I read the RMAN manual and I'm quite familiar with backup a tablespace or data file, but I can find very little uses for it. Backup upward a tablespace is useful for the TPITR, but since who needs another instance sound very little useful in most production environments. I think that you cannot restore an older version of tablespace in a normal database, except if the tablespace has been done long read-only, in which case RMAN optimizations will do the trick.
  Still less use that I can find for the backup of the data file. I have absolutely no idea of what you can do with a single data file.
  
  Can you please tell me about the uses of these RMAN features?
  
  Thank you.

  Hi again!

  OK, you're right. If you are using noarchivelog moden then a partial database backup is no useful. Only the archivelogmode can make a useful partial backup of DB.

• PATTERN SIZE AND SIZE OF TABLESPACE

  Hi all
  I have a dolphin3_t of schema and only used by him, other than system, temp and sysaux tablespace is PHIN_DATA1. Last night a time problem where space exceeded for tablespace but the scheme as such has 19 GB size where as
  the tablespace has 32 gb (maximum value), but a data file has been added to with 32 GB storage space. But how is that possible.
  
  SELECT Sum (bytes) / 1024/1024/1024 OF dba_data_files WHERE nom_tablespace LIKE 'PHIN_DATA1 '.
  61.6015625
  
  SELECT Sum (bytes) / 1024/1024/1024 OF dba_segments owner WHERE to = "DOLPHIN3_T."
  19.25311279296875
  
  If the first statement to query a value less than that given by the second query.
  Note: The storage space is used by dolphin3_t schema only.
  
  My guess is that the other guy shift mistook the lack of quota for lack of space in the data file.

  You cannot merge... but a way around this would be...

  check wat objects in datafile2... then based on that create a different tablespace

  move the object of datafile2 for the new tablespace...

  fall of datafile2...

  give your old tablespace that will datafile1 the purpose of the new tablespace creation.

  for example...
  ALTER table TableName move tablespace;
  ALTER index indename tablespace rebluid;

• Trying to create a Section to multiple columns with Sections of the single column before and after

  Is there a way to create a section break that is not default to a new page after I created columns on a page.  I created the columns and under them, I want to return to the normal formatting for the rest of the single page.  See picture attached.

  Any rejection of Pages v5 has a break of presentation which was present in the Pages ' 09 v4.3. This will allow you to transition to several columns and back to single column on the same page. In the v5 Pages, you can insert 3 text boxes and change the 3-column layout in the Middle text box. You use the toolbar item Insert to inject column breaks when you want to start a new list in the next column. I'll show this screenshot below.

  You can fake your layout in Pages v5 using 3 text boxes and setting 3 columns in the Central text area. Better to show the mode of provision for this and in a text box, the column outlines are not displayed. After each column list, you then choose column break the Insert point toolbar menu to move to the next column, add a list, repeat. Each column will expand downwards. Click on the following to enlarge.

• Possible strategies to restore a single tablespace of the instance A B

  Hi all
  
  Then...: Win 7 64 bit
  ... DB: Oracle 11.2.0.3 EE 64-bit
  
  In my notebook, I have 2 instances (orateste and ora11). They are all intended to test. I don't know what happened, but a problem in a partition of my SO did the unavailable Oracle software. I can't start the instance orateste. Even the windows service that is associated with the instance have disappeared from services.msc. What I want to do is to restore only a tablespace for instance orateste to ora11. I have a full D - 1 rman backup. What are the possible solutions?
  
  (1) to restore the entire database (orateste - 11.2.0.1) ora11 (11.2.0.3)?
  
  (2) is there a way to restore only a tablespace between instances and versions?
  
  Thanks in advance.

  Reinstall the software
  (1) how to create a windows service? Prompt caommand

  oradim-new - sid - intpwd

  If it helps, and take an export of all objects in this table space and import into another database, you can start your old database.

  OR

  Restore the full database using RMAN somwwhere else and that the export of take it from all objects in this tablespace and import them into another database.

• How to get the original size of pictures? Microsoft office Picture Manager

  I used household image and all my photos are made smaller, but now I want size beck to original size. How can I do?

  You can enlarge the current versions of the photos
  in the photo... Manager using custom or
  Options of percentage but there is no way to return
  to the original version in Office Picture Manager.
  Extended versions is not the same quality
  than the originals.

  Info about photo manager
  If you resize a photo with Picture Manager and
  save it when you see the dialog box saying:

  "There are changes that have not been saved"

  The original photo will be overwritten (replaced)
  with the rezized version... IOW the original will
  be unrecoverable.

  To keep two versions of the picture, resize it
  and go... File / save as... Enter a new name for
  version resized and on the left, click on the "Save" button.

  When you close the photo manager and see the
  dialog box:

  "There are changes that have not been saved"

  On the left, click the do not save"" button. Now
  have both versions.
