• Specify the tablespace for table main expdp?

  Is it possible to specify what the main table tablespace will be created in an expdp job?
  
  I'm carrying the default tablespace for the user who runs expdp and obviously expdp cannot create the main table because the tablespace is read only for transport. I am looking for a way to specify a different tablespace for the main table without changing the user's default tablespace. Such a thing exists in 10g or 11g? TIA

  Chuck1958,

  I don't know that such a setting Exit (or not)... On the other hand, here's another way:

  You can create a new user, give him required privileges and, on the other hand, starts the datapump export by this new user using the parameter "schema".

• East - the usual/recommended that users have TABLEs in the spaces of multiple tables?

  As I discovered new TABLEs of users created in spaces of multiple tables for example

  A user can create its tables in different tablespace when there quota on special tables,

  If the default tablespace is not given while creating the table then default tablespace for the user schema will be used.

  To restrict the use of the SYSTEM tablespace, use the command below

• Move the table in same tablespace is not reorganize the data

  Hello.

  I am facing a problem that I have not used to have.  First of all, a description of our envorinnement:

  We have a few large tables partitioned and performance optimization, our ETLs use bluk, add notes, parallelism and so on.  This create several holes of unused space in tablespaces/data files as well a kind of leak of space on our drives.

  A complete correction would re-create the tablespaces move everything is of opposes another.  It would be impratical, because there are about 15 who are top of 100 GB; the time and effort to recreate everything is not affordable for the Business.

  Instead, we have a single proc that comes to calculate the actual amount of used space (converted to blocks) and makes a move of all objects above this block_id.  Just after this operation, there is a dynamic shrink based on the new HWM (given that the objects have been moved) on the data file freeing disk space.  As we have a datafile by tablespace and a tablespace by schema, we would like to keep this body, if we make a single movement for objects, like 'ALTER TABLE' | owner: '. ' || nom_segment | "MOVE; "(the complete query works with all types of data such as partitions of table objects, the index partitions and the subpartions).  This will move the object in the same space for the first freespace on the tables and free up space at the end of the file to shrink.  In theory.

  This unique proc used to work properly.  In a 650 GB GB 530 tablespace in use moving about 20 that Go (the amount of data beyond the HWM 530 GB) is simpler than to create a new file/TBS and the displacement of 20 GB is faster than Go 530.

  But suddenly things changed when some TBS refused to be narrowed.  What I found out: the command move doesn't fail, it works very well and Oracle really moves the object.  But for reasons that I don't know, he's not moving it at the beginning of the file, it keeps the object at the end.  So the da calculates the new HWM, but because some objects that were in the tail of the queue, the shrink is done with a very high HWM, if no real space is reclaimed.

  So, the main question: How does the ALTER TABLE FOO MOVE really works?  I thought that it would be always to move the object to the beginning of the file thus reorganize, but I analyzed the last objects that gave me this problem (block_id before and after the move, compared to block_ids empty and everything) and actually, I see that they were moved at the end of the file, although there is enough space to accommodate initially.

  Okay, I think I found the problem.  Before that I just pulled the script as posted, but then I had the good idea to improve its performance with parallelism, so I added:

  ALTER SESSION FORCE PARALLEL QUERY 16 PARALLELS;

  ALTER SESSION FORCE PARALLEL DDL PARALLEL 16;

  ALTER SESSION FORCE PARALLEL DML PARALLEL 16;

  Returning to prallel not running, that I could reuse the freespace on the beginning of the file, and then narrow it down.

  Obviously, each writing data in parallel mode reuse freespace, I just forgot that a TABLE ALTER MOVE is also a data write operation.  I fell a bit ridiculous, caught in the same trap that I was trying hard.

  Thank you all for the comments and advice.

• How to get the table without segment tablespace

  Hello

  I have a few tables in 11.2, which were created with creation of deferred segment and did so no segment/measure not yet. They already appear in dba_tables thus identical to the tab$, but do not have a defined tablespace.

  However, using dbms_metadata.get_ddl () the DOF resulting has the correct tablespace name. But what a view or table that I must query for this information with SQL?

  Thank you

  Robert

  Hello

  No, none of these tables is temporary, but it turns out that all the affected tables are ITO and so I have to check dba_indexes for the tablespace and the dba_indexes index_name when looking for a segment.

• Security move the table to another tablespace

  I would like to pass on my table to a different tablespace by using the statement:
  ALTER TABLE table_name move tablespace new_tablespace;
  
  I am interested in what happens if someone wants to select or modify some data during the process of alteration (on the table table_name). I tested on the database of test (without a users) and everything was OK, but I wonder what happens if someone edit or select data. Could you recommend me how to protect this table? Change in playback mode or change the database in the mode of restriction? Thanks for the tips.

  Hello

  The table is locked automatically during the MOVE ALTER TABLE. If other sessions can still perform selects, but no changes can be made during the DDL.
  Don't forget to re-create the indexes on the table later.

  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.

• 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.

• ORA-01659: impossible to allocate MINEXTENTS beyond 2 in the tablespace test

  Hi @Suri

  I see no problem in storage settings in your table.

  But the number of rows helps you insert and in the free space in your tablespace.

  Perhaps too much space is needed for your data and storage space can not support.

  The only things you can do is the following:

  (a) try PCT_INCREASE to 0, this product extensions to equal size.

  (b) put the PCT_FREE less than the default of 10. But it is advisable if you make updates to your table.

  (c) maybe create your table with the clause compress, just for bulk inserts, but this depends on the use of the table.

  (d) ask your DBA to increase the data files of the TEST table space or add more data files.

  (e) using the package DBMS_SPACE, you can calculate the space used by your table in tablespace TEST. g 10 and later versions.

  See the following example:

• Changing table via the package with immediate execution (problem)

  Hello

  I have a unusual problem. I have a package that contains the procedure that via execute immediate statement, creates a table on which he performs different actions for example:

  -alter table some_owner.dummy_table noparallel

  -create index some_owner.idx_name on some_owner.dummy_table (column)...

  But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.

  Note If call these commands outside the package (a simple script) this all done OK.

  I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.

  I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.

  There must be a problem why a package cannot change the table which is owned by the user 'SOME_OWNER '.

  All useful responses would be appreciated.

  I have a unusual problem.

  No - you don't have. This question has been answered SEVERAL times on this forum and others.

  But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.

  OK - your username doesn't have privileges to do these operations or only received privileges through roles.

  Roles are DISABLED in named PL/SQL blocks that use of the AUTHOR's rights.

  Note If call these commands outside the package (a simple script) this all done OK.

  I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.

  Of course - the roles are NOT disabled in named PL/SQL blocks that use the rights of the APPELLANT or in anonymous blocks.

  I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.

  Well now you know!

• 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?

  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.
