• Push all the objects in a tablespace to another

  Hello

  on the 11g R2 (11.2.0.3)

  We need to move all the objects in one tablespace to another.

  Is this possible?

  How can we push all the objects of a logical disk space to a different tablespace?

  Thank you.

  Generate the

  ALTER TABLE TableName MOVE TABLESPACE new_tbsname
  and

  ALTER INDEX REBUILD new_tbsname IndexName

  orders.  You can use "SQL Generation of SQL" or write a PLSQL WHERE USER_SEGMENTS loop.

  If you have some LOBs you must move the LOBs using
  ALTER TABLE TableName MOVE LOB (lobname) STORE AS LOBSEGMENT (TABLESPACE new_tbsname)

• Name of the dynamic property of object in the table based on the value of a variable

  I have two paintings of custom class objects

  var obj1:Object1
  var obj2:Object2
  
  var array1:Array = [obj1[0], obj1[1], ...]
  var array2:Array = [obj2[0], obj2[1], ...]
  

  Object1 has a property named. Name while Object2 has a property named. Title.

  Now I have a common function including cab accepts an array (array1 or array2) and the name of property the object ("Name" or "Title") as input and needs to access this name of the property of the objects in the array:

  function myFunction(arr:Array, fieldName:String)
  {
      arr[0].fieldName  = "xxx";
  }
  

  the problem I have this achievement does not because the code in the function assumes that the property of that object in the table is actually a string "fieldName" while I want to dynamically determine the names of the fields based on the value of this variable, but cannot understand the syntax to do!

  Don't know if I'm clear - hope that makes sense... ;-) Thank you

  Hey p3pp3r,

  I think I understood you. Try the following and see if you get good results:

  function myFunction(arr:Array, fieldName:String)
  {
      arr[0][fieldName]  = "xxx";
  }
  

  Let me know how it turns out. Good luck!

• Defragmentation of the tablespaces?

  DB version: 11.2.0.4

  Platform: Oracle Linux 6.5

  3-node RAC DB

  We have a TB 23 DB, and we met some performance issues lately. Sound mainly due to poorly written queries, large volume of data in the result set,... etc. But, this application was asked at a meeting if I could check that storage space (not tables) are fragmented. Apparently, in his old store DBA there did some 'Defragmenting' of tablespaces for the same application solve some performance problems.

  To resize the data files, move to another tablespace DB objects so that the HWM in a particular data file is reset and then we could run the RESIZE command. But this isn't "defragmentation".

  In the thread below, Justin cave explains that "a managed tablespace locally cannot effectively be fragmented."

  That Justin is meant by that? Why have we not need "defragmentation" to locally managed Tablespaces?

  Since I worked on 11g, I don't know the history. Done, DBA do a sort of defragmentation for older versions?

  https://community.Oracle.com/thread/2508361

  In general, you don't need to defragment of LMT because they re - operate segments more effectively.  That assumes a particular definition of the fragmentation that don't understand what some people call "Gruyère" fragmentation, which means free space holes, spread across the tablespace.  Sometimes it is wise to reclaim this space, generally do not, since generally the trend is to use space.

  Many more details are in the link given Aman, but there are a few somewhat obscure situations where you would not automatically exclude the defragmentation:

  A tablespace that has been migrated from DMT could have a few deferred maintenance on the lookout for defragmentation.

  You might still have DMTs.  You shouldn't, but there is nothing no longer this deferred maintenance upgrades of version (I do not forget something hope).

  Some applications do stupid things like add and remove tables and if done in a strange order (as drop any other individual and adding more), can travel on limits of segment requirements (as Jonathan explains in some links on the moving objects until the beginning of storage spaces).

  It is also possible to be unlucky and have performance issues based on the distribution of physical data get worse by moving data autour.

  In general, Oracle did some good things, but be prepared to do an investigation of mind, when it is not.  It allows to be confident and knowledgeable on the bases then.  For the 'fragmentation' in particular, a Manager may well have been seduced by myths or the specific practices that don't apply generally. "Best practices" may suffer, too.

  (c) file the original tablespace

  (d) create the original tablspace with autoallocate option

  (e) return the MASTER tablespace tablespace original objects by using similar scripts above.

  Everything works fine and the objects are themselves moved back correctly, we are able to see objects, tables, the lobindex and the lobsegments in storage space, but when we question "select object_type, count (*) in the dba_objects where owner = group 'SYSADM' by order of object_type by object_type;" The number of object decreases after each TABLESPACE.

  Could you please shed some light on this?  Very busy tasks so he couldn't think why its happening.

  Thank you

  Here, the number of object is not changed.

  Now, a tablespace has no object.

  ...

  Please, show us queries that you use for each and every one of these steps.

  In addition, you are on 11.2, this means an object may or may not have a segment based on the DEFERRED_SEGMENT_CREATION init parameter (TRUE |) FALSE, TRUE by default), or how the object was created. Your script may fail to see objects with no segments (the scenario is based on dba_segments), but your account is based on dba_objects...

  Basically, after A move to MASTER, the number (on dba_objects) does not change because the empty segment objects are still there (dba_objects). Once the tablespace is deleted, objects from empty person to load (without segments) are also deleted, result: the count on dba_objects is declining.

• collect statistics for the tablespace

  Friends...

  OS: Linux

  DB: 11 GR 2

  Data size: 1 TB

  I spend monthly multiple partitioned table spaces and bring together in a single annual partition. (for example tbs_2014_01, tbs_2014_02 - tbs_2014_12... all combine them into tbs_2014 as a tablespace)

  Over the weekend, work of database gets executed that collects statistics that are obsolete, it collects all the segments that have been moved from the storage.

  Given that the collection of statistics at the end of the week takes too long, I tried to find a smart way to collect statistics after each tablespace move rather than waiting for job to weekend which will take two or three days to complete.

  1. is there a way to gather statistics at the tablespace level and collect statistics for all objects in this table space?

  2. how to determine the overall stats of collection of statistics part?

  That is, suppose I have move the tbs_2014_01 tablespace and collect statistics with global stats that could take 2 hours but it will be difficult to spend 2 hours for each stats global tablespace which in my opinion is not good and we should be collecting global stats only once.

  3. any other advice?

  @sol.beach... Thanks for your comments...

  I've not been asked to collect statistics to the tablespace but level to collect statistics after that finish objects move in storage.

  Given the size of the data, it is difficult to gather all the statistics at the weekend so trying to understand another method to collect the statistics the weekend load will be less.

  You can collect statistics object on an object by object basis level after that each object has been moved.

• Diffrence between the tablespace is ONLINE and READ WRITE?

  Hi all

  I'm very confused on the tablespace is ONLINE and READ WRITE?

  Some say that if the tablespace is online, this means that its READ WRITE and when its offline then its READ-only.

  So, what is the difference between them:

  ALTER TABLESPACE offline tablespacename; -> done mean READ only now?

  ALTER TABLESPACE tablespacename online; -> is it means its READ WRITE now?

  If Yes, then what is the use of the following command if above 2 commands? :

  ALTER TABLESPACE tablespacename [READ ONLY |] READING WRITING];

  Kind regards

  Confused Ritu

  In addition, when the tablespace is offline, objects belonging to those who are not available for use to users. You wouldn't be able to query for objects in a tablespace offline.

  When the tablespace is read only - no write operation cannot be performed i.e. etc. INSERT/UPDATE/DEL. Oracle says that read-only tablespaces provides a way to protect the historical data so that users cannot modify it. You can drop objects, such as tables or indexes, to a tablespace read-only, but you can't create or modify objects in a tablespace read only

  In order to bring a tablespace OFFLINE to ONLINE - so that it is available to users, you must "ALTER TABLESPACE online tablespacename" command. A tablespace online can be READ ONLY or READ WRITE mode.

• Add the object in the list

  Hi how are you guys? I hope you all well...

  here...

  IAM trying to show the list items in the list... but I couldn.t here

  first I created the object and the array object

  var za:int = 0

  var itemsinfo:Object = new Object()

  var da: Array = new Array (100)

  ...

  then in another place, I set the properties for the object, andi made paintings objects like this

  Itemsinfo.name1 = new Array()

  Itemsinfo.price1 = new Array()

  After that i, ve packed 2 text boxes, one for the value of the element and the second for the price

  additemsvar = additems.text

  addpricevar = int (addprice.text)

  then I checked the values in the object

  for (var z: itemsinfo String) {}

  trace (z + ":" + itemsinfo [z])

  }

  and everything is good, but the problem is when I add these berries to the list object, it doesn, t work

  i.ve tried with 3 deffrent ways

  ListBox1.AddItem ({label: String (itemsinfo.name1 [za])}) //displaying not defined in the list

  listBox1.AddItem ({label: (itemsinfo.name1 [za])}) //displaying nothing and it just take a place

  listBox1.AddItem (itemsinfo.name1 [za]) / / nothing happened

  Thank you

  Itemsinfo.name1 is initialized (in a table), but contains no items for the zero element'th will be undefined.

• Question about AUTOALLOCATE and UNIFORM in the tablespace management

  Good afternoon
  
  I'm unclear as to if a UNIFORM extent allocation means that the data file must be manually extended or not.
  
  Documentation:
  
  >
  The following statement creates a managed tablespace locally named lmtbsb and specifies AUTOALLOCATE:
  Lmtbsb CREATE TABLESPACE DATAFILE ' / u02/oracle/data/lmtbsb01.dbf' SIZE 50 M
  EXTENT MANAGEMENT LOCAL AUTOALLOCATE;
  
  AUTOALLOCATE causes tablespace system managed with a volume of minimum extent of 64K.
  
  The alternative to AUTOALLOCATE is UNIFORM. who says that the tablespace is managed with uniform size extents. You can specify the size of the uniform SIZE clause. If you omit the SIZE, the default size is 1 M.
  
  The following example creates a tablespace with uniform extents of 128 K. (In a database with 2 K blocks, each would amount to 64 blocks of data). Each measure 128K is represented by a bit in the bitmap extent for this file.
  Lmtbsb CREATE TABLESPACE DATAFILE ' / u02/oracle/data/lmtbsb01.dbf' SIZE 50 M
  EXTENT MANAGEMENT UNIFORM LOCAL 128K SIZE;
  >
  
  It is clear that the clause UNIFORM control the size of the scope which will be awarded, but doesn't really say if these will be assigned manually or automatically. In other words, I'm not clear as to whether or not the data in the second case file will be automatically extended.
  
  In my test environment, when I published the command:
  

  SQL> create tablespace largetabs datafile 'E:\Oracle\app\Private\oradata\dbca\largetabs.dbf' size 100M extent management local uniform size 16M;

  and only looked into the tablespace EM I had created above, there is no check mark in the box "Automatically extend datafile when full", which led to the doubt that I have now.
  
  Is: during the extended allocation is UNIFORM, this means that space must be allocated manually or can the renewed automatically datafile? If it can be automatically extended, I would appreciate an example of a create tablespace command that allows to achieve this result.
  
  Thank you for your help,
  
  John.

• What is the reason for the tablespaces exist?

  Hello
  
  If I can store in a tablespace of data of different users / schemas / apps and also a user data / shema / application in several storage spaces. What is the meaning of a tablespace?
  
  What is the reason for the tablespaces exist? Only to assign the storage space and know where are the objects of the user? Is it not possible to work with data directly files instead of doing with the tablespaces?
  
  I'm afraid I'm too philosophical today but I do not understand why the structure of the tablespace.

  Hello

  Apart from the above, I'll add the storage capacity of a Tablespace.

  A Tablespace usually (default is a petit_fichier Tablespace) can have up to * 1022 * data files. And (in the case
  petit_fichier Tablespace) each data files can be big 4 MBlocks.

  So if your db_block_size is 8 KB your Tablespace can store up to 1022 x 4 M x 8 KB ~ 32 to data.

  More, these 1022 data files can be located on separate disks. So it can give you plenty of opportunity.

  However, from 10g you have a new type of Tablespace: bigfile Tablespace.

  Bigfile Tablespace has only 1 data file, but it can reach 4 GBlocks. So finally this Tablespace can store
  also 32 to (for 8 KB db_block_size) but, ensure you that your OS platform and system disk can support
  a big Datafile.

  The syntax for the statements that manage the data of a bigfile Tablespace file are too different. In fact, you can
  manage this data at the level of the Tablespace file.

  Please find attached a link to bigfile Tablespace:

  Additional storage of pl/sql code

• Unlimited on USERS quota of USERS of the tablespace default ALTER USER &lt; schema &gt;

  Hi all
  
  I got a schema called dmuser1 which I had assigned to tablespace "odmperm."
  now, I was running short on space in the drive on which oracle is installed and
  There was a 'odmperm' tablespace data file,
  so I thought to drop the tablespace "odmperm" and the corresponding data file,
  so I modified the schema dmuser1 to point to the USERS tablespace in the race code below
  
  ALTER USER dmuser1 quota default tablespace USERS unlimited USERS.
  
  so I ran
  Select * from dba_users;
  
  Here user dmuser1 had changed users tablespace, so I used the command to remove the file from the data below
  
  DROP TABLESPACE INCLUDING CONTENTS ODMPERM;
  
  now, when I log in the dmuser1 schema, none of my paintings are present and I don't have the backup too, so please help me solve this.
  
  
  Please, I beg you.
  
  Thanks in advance.

  You are out of luck - the paintings disappeared and without backup or export, you will get their return. If you still have the data file on the file system, contact the Oracle Support and ask DUL - that is if you have a support contract. No other chance, I'm afraid. Your command alter user only had an effect for future tables :-(

• organize data for the tablespace files

  Hi all
  
  I would like to ask you if you have a way to organize a tablespace (especially USERS) using 10 data into 1 single file of data files.
  
  You have a way to reorganize a database during the work day, so the watermark will go down, but without making a copy of storage space?
  
  Thank you for taking my question into consideration.
  
  Concerning

  Hello
  I suppose that, if I understand you correctly as a Remap_tablespace with a Tablespace rename DataPump could help you.
  This,
  (1) create a tablespace again with a single good size in data file to hold your all objects. You may need to calculate the size of the data file.
  (2) export all the objects, or better, the schema itself, of the current storage space, we call it source at this time using data pump.
  (3) using the DP import, import the given in the new tablespace, we call it target with option Remap_tablespace = Source: target.
  (4) once done successfully, drop the tablespace from source.
  (5) and rename the target source.
  You would get a tablespace with a data file and all the objects inside.
  HTH
