Running in parallel DML not forced

• Oracle 11.2 - perform parallel DML on a table that is not partitioned with LOB column

  Hello

  Since I wanted to demonstrate the new enhancements of Oracle 12 c on SECUREFICHIERS, I tried to use PDML declarations on a table that is not partitioned with LOB column, in Oracle 11 g and Oracle 12 c releases. The Oracle 11.2 SECUREFICHIERS and large objects Developer Guide January 2013 said clearly:

  Parallel execution of the following DML operations on tables with LOB columns is supported. These operations performed in parallel run only mode when it is run on a partitioned table. The DML statements on tables not partitioned with LOB columns continue to run in serial execution mode.

  • INSERT SELECT AS
  • CREATE TABLE AS SELECT
  • DELETE
  • UPDATE
  • MERGE (conditionally UPDATE and INSERT)
  • Multi-table INSERT

  So, I created and filled a simple table with a BLOB column:

  SQL> CREATE TABLE T1 (A BLOB);
  Table created.
  

  Then, I tried to see the execution of a parallel ABOLITION plan:

  SQL> EXPLAIN PLAN FOR
    2  delete /*+parallel (t1,8) */ from t1;
  
  Explained.
  

  SQL> select * from table(dbms_xplan.display);

  Is this normal? It is not supposed to be supported on Oracle 11 g with no partitioned table containing the LOB column...

• Why this parallel DML statement is not run as fast as DBMS_PARALLEL_EXECUTE?

  Hello

  I'm on the database Oracle Enterprise Edition, Linux RH 11.2.0.3. I have a pl/sql function that accepts a sdo_geometry (essentially an object with a few varrays), round each number in one of the varrays and retransmits the object.  Here is a version of the function, simplified slightly for brevity:

  create or replace round_coordinates (p_geometry in sdo_geometry, p_round_factor in numbers)

  return sdo_geometry parallel_enable

  is

  sdo_geometry v_geometry: = p_geometry;

  v_ordinates sdo_ordinate_array;

  Start

  v_ordinates: = p_geometry.sdo_ordinates;

  for me in v_ordinates.first... loop of v_ordinates. Last

  v_ordinates (i): = round (v_ordinates (i), p_round_factor);

  end loop;

  Return sdo_geometry (v_geometry.sdo_gtype, v_geometry.sdo_srid, v_geometry.sdo_point, v_geometry.sdo_elem_info, v_ordinates);

  end round_coordinates;

  /

  I need to perform this function as an update DML on hundreds of millions of sdo_geometry objects and according to my estimates it will take weeks.  So, I want to run in parallel.

  The data is in a bunch of tables, some with lines of k ~ 100 more with millions of people.  My preference is to browse the tables and run an update such as:

  Update < table > set geometry = round_coordinates (geometry);

  But I would like to operate in parallel, so I thought that I would allow the DML parallel to the session with

  ALTER session enable parallel dml.

  ALTER table < table > parallel;

  , and then run the update by: Update / * + parallel * / < table > set geometry = round_coordinates (geometry);

  When I do that, I can see a v$ px_session 16 parallel slaves are bent and the plan of the explanation is the following:

  ------------------------------------------------------------------------------------------------------------------

  But the update statement on my test data set does not any more quickly - it takes a few seconds more series that suggests General fresh extra expectations for the management of parallel slaves that's happened, but they did not have the query run faster.

  
  I tried to use the dbms_parallel_execute with the create_chunks_by_rowid option package and parallel_level = 16 With that I get at the end just over 1/16th of the time that it takes to run in series!

  That's fine, so I have the option dbms_parallel_execute, but I would like to understand why the query with the parallel flag does not expedite things.

  Any ideas?

  Thank you

  John

  It may be that the call to the PL/SQL function slows down things. Did you think to do in pure SQL?

  Here is an example:

  update test_sdo tsd
     set tsd.geometry.sdo_ordinates =
         (select cast(collect(round(t2.column_value)) as sdo_ordinate_array)
            from test_sdo t1
                ,table(t1.geometry.sdo_ordinates) t2
           where t1.id = tsd.id)

  BTW: You can parallelize the query part of the SQL but not updating, it's documentation:

• Parallel DML may be downgraded to the DML series?

  Oracle Database Enterprise Edition 11.2.0.3.0

  When you run a parallel query (e.g. SELECT * FROM parallel_table WHERE a <?), the optimizer may choose a parallel or series, the selectivity of the predicate function plan and availability different access roads - usually a scan interval series index for highly selective queries (a small number of return lines), and a parallel table full scan for less selective queries (returning a large number of lines).

  However, with parallel DML enabled, no such optimization seems to happen. There may be a very effective for a query as series plan "DELETE FROM parallel_table WHERE a <? ', but once parallel DML is activated, the optimizer based on CSSTidy always seems to choose a parallel plan.

  Is there a way to allow the optimizer to choose between series and parallel DML according to predicates in the query? I wish I could enable parallel DML, but knowing that, in the case of a very selective, query optimizer will not parallel DML use but will use a series DML.

  Note that I'm allowing to the DML, not no force in parallel it (although it seems more to do with the fact that a table series is considered parallel, without having to refer to the query).

  Here is an example of this behavior, deleted 18 m rows in a table of rows of 300 m:

  First, the cost of a DML series operation is 59,000, using an index to access the lines:

  COMMIT;

  ALTER SESSION DISABLE PARALLEL DML.

  DELETE

  OF parallel_table

  WHERE the DATETIME_a < sysdate - 650;

  ---------------------------------------------------------------------------------------------

  | ID | Operation | Name                    | Lines | Bytes | Cost (% CPU). Time |

  ---------------------------------------------------------------------------------------------

  |   0 | DELETE STATEMENT.                         |    18 M |  2037M | 58723 (1) | 00:11:45 |

  |   1.  REMOVE | PARALLEL_TABLE |       |       |            |          |

  |*  2 |   INDEX RANGE SCAN | IDX_PT_DATETIME_A |    18 M |  2037M | 58723 (1) | 00:11:45 |

  ---------------------------------------------------------------------------------------------

  Now, by allowing parallel DML, the optimizer chooses a parallel full table much more expensive for the same request, cost 926 000 scan. Why he won't come back in terms of the series?

  COMMIT;

  ALTER SESSION ENABLE PARALLEL DML.

  DELETE

  OF parallel_table

  So in summary, by adding a second index to the table, the optimizer computes a much higher estimate of the costs for the use of a scan of the index systematic range. As a result, he opts for the full table scan, which is not necessarily the most efficient plan. I am inclined to think that it is a bug with optimizer, as much as it manifests itself only in the line superior (0) plan.

  It's a pretty good reason to be suspicious - and I think you are right that it is a bug.

  The cost of a removal is the cost of the selection the ROWID of the lines to remove, which is in this very simple case: ' selectivity * leaf_blocks ' for the index. However, when you create the second FINAL cost index seems to change to "selectivity * (leaf_blocks + clustering_factor) ' (I ran your test case, tried a few simple variations and looked 10053 files trace - so my conclusion is not a complete analysis of the question.)

  Since you have a test case, raise a SR with Oracle.

• Question about parallel hint and 'alter table enable parallel DML'

  Hi all
  
  I have a DML as follows:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW;
  
  Here complex_view contains a very complicated SQL, in which there is some heavy tables joins, subqueries, and aggregations.
  
  Question 1:
  
  Let's assume that the underlying tables have no attribute "parallel." Where should I add "parallel index" to force it to be run in parallel and can get better performance?
  
  Some members think that what follows is good.
  
  Insert / * + append * / into table1
  Select / * + parallel (a 4) * / *.
  of COMPLEX_VIEW;
  
  But I think that indicators must be put in the defintion of the complex view where they should be and do not put advice to the main insert DML, like this:
  
  Insert / * + append * / into table1
  Select *.
  of COMPLEX_VIEW; -I added the indicators in the COMPLEX_VIEW.
  
  What is your opinion?
  
  Quesion2:
  Without ' alter session enable parallel DML ", I can see the parallel session in v$ px_session thus." And the execution time has been shortened. This proves without this statement, the DML is also run in parallel.
  
  So, what is the effect of this statement?
  
  Best regards
  Leon

  I prefer the suspicion out of the COMPLEX_VIEW. This way, only this application forces the suspicion. If you put the indicator in the COMPLEX_VIEW, any other query on COMPLEX_VIEW (or Assembly of COMPLEX_VIEW to another view or a table) would also "encode" indicator in its execution. You don't then isolation parallel query to only where it is needed.

  If you put the parallel indicator in SELECT it (or view), the query is parallelized. This does not necessarily mean that the INSERT is parallelized. What you see v$ px_session are only slaves to PQ to SELECT.
  You must ALTER SESSION ACTIVATE PARALLEL DML and add the PARALLEL indicator in the INSERT.

  The statement above with Alter command and parallel Hint improve the performance of DML.
  
  Please suggest me.
  Thank you

  If we want to execute DML instructions in parallel, that we must allow the parallel DML for the session.

  The statement above with Alter command and parallel Hint improve the performance of DML.

  Yes. N ° maybe. Sometimes.

  If parallelization (dread Word) makes things run faster depends on many things. The number of cores has your server. How many other processes use the system at the same time. If there is a reasonable plan to organize the parallel threads. Into the INITRANS of the table settings.

  Parallel SQL is an important area that has a lot to understand. The best place to start is with Doug Burns paper on the subject. [url http://oracledoug.com/px_slaves.pdf] Find it here (attention: PDF)

• You need to pass arguments to the Sub - VI which runs in parallel to the main vi.

  Please help me.

  I can pass arguments to a subvi using "call-by-reference-node" but the sub - vi will not work in parallel.  I can also run my sub - vi in parallel using "invoke the node", but then cannot pass arguments.  I can't understand how to merge these two concepts.

  When I open the reference VI, I specify the strict type, using call-by-reference-node.  When I use call node, I don't specify the type.  It seems that specifying the type strict guard screw run in parallel, but also seems necessary to pass arguments.

  I apologize for my absence of a deeper understanding of this and appreciate any help you can give me.

• Prerequisites for reentrant SubVIs to run in parallel

  Hello!

  In my VI, two clones préallouées of a Subvi, I thought I would go in a separate thread of each. Just this sub - VI contains a reference to a double and it increments. The two clones ran in parallel, but not in separate threads. For comparison, I did a Subvi, which does not have a reference - these clones run each in own thread.

  I noticed this watching the CPU usage: in the first case, has been used as a single core in the second respectively two sons were used.

  (1) I wonder what are the prerequisites for a Subvi to run effectively not only in parallel, but in fact in separate threads?

  (2) is there a way to discover during compilation which (Tufts) parts of a VI run in parallel, and SubVIs get making their own thread of execution?

  For reference: the execution is slow. If I understand correctly, the GUI is running in its own thread, so no interfering only not with the SubVIs that multiply references. I think that there is also no locking a reference readings and writings to a reference should be very fast. Is this correct? If so, why is this slow running?

  Thanks for your replies

  (The test computer has a Quad-Core with Hyperthreading, using LabVIEW 2012SP1)

  One thing I know is if you have any manipulation of the UI elements.

  In the case you use a reference to a UI element user and properbly using the property node to insert data.
  This limits LabVIEW for your sub vi of in the UI thread.

  If you have transferred the values on the queue to a vi that manages all the user interface controls, then only that vi will be in the UI thread.

  Run-update - $Templateslist - vcenter $vcenter models - session $global: DefaultVIServer.SessionSecret - $script - $guestuser guestuser - guestpass $guestpass script

  I found the solution!

  I just add this string - $WarningPreference = "SilentlyContinue" in an inline script

  Like this:

  {of workflow run-update

  (param

  [string []] models of $,.

  [string] $vcenter,

  [string] $session,

  [string] $script,

  [string] $guestuser,

  )

  for each-parallel ($vm in $templates)

  {

  $run = {InlineScript

  $WarningPreference = "SilentlyContinue".

  Add-PSSnapin VMware.VimAutomation.Core

  SE connect-VIServer-Server $Using: vcenter-Session $Using: session

  Invoke VMScript - ScriptText ' $Using: script "-VM" $Using: vm "-Server" $Using: vcenter '-GuestUser ' $Using: guestuser '-GuestPassword ' $Using: guestpass»

  Remove-PSSnapin VMware.VimAutomation.Core - ErrorAction SilentlyContinue

  }

  $run

  }

  }

  $script = "c:\update.ps1".

  $guestuser = "administrator."

  $guestpass = "myPASS".

  Run-update - $Templateslist - vcenter $vcenter models - session $global: DefaultVIServer.SessionSecret - $script - $guestuser guestuser - guestpass $guestpass script

• With the help of DAC for running no BIApps infa jobs n 2 EP running in parallel

  Hello
  
  We already have configuration BI Apps prod environment using DAC, Informatica and OBIEE 11 g for one of our customers.
  
  Now, we want to check the possibility of using the DAC for the execution of BIApps no informatica related jobs.
  (That we had only a week of the execution plan of DAC weekend and Informatica and DAC are inactive most of the time during the week)
  
  Customer wants a separate new small datamart be configured which meet the requirements of statement for different departments and has no links of kinship or any link with existing BI Data Warehouse applications.
  
  I just wanted to check if it will violate the license terms (if we use CAD to workflows not BI Apps and run another EP)?
  
  In addition, the DAC Build 10.1.3.4.1 is capable of running two parallel execution plans?
  
  We have heard long back that two parallel feature EP will be lunched in the version 11g CAD. Pointers or new in this space?
  
  Thanks in advance,

  From what I remember, you cannot load a 'distinct' DB instance that is NO OLIVIER. If you create a small custom datamart on the INSIDE of the OLIVIER exitsing schema, then it is acceptable. However, if you use DAC (no matter if its plan one or two plans) to load a NON-OBIA target, this may violate the license agreement. You need a self-contained separate license for Informatica and use the planner of Informatica tool. If you want to use DAC, ensure that your target is inside the DW OBIA.

  Pls correct brand...

• List of jobs run in parallel

  Hello
  I use DBMS_FILE_TRANSFER. PUT_FILE as part of my portable from tablesspace shell script
  my intermediate dwh instance to my instance of dwh report.
  
  The problem is that I face the data files after one.
  There are about 20 files of data, and each of them is 10 gigabytes in size.
  I would like to copy the files in parallel and not after one.
  
  I thought to create dynamically 20 jobs/Scheduler (based on the number of data files) and all run togther.
  This way I could actually run in parallel.
  Bellows is part of my TTS shell script.
  The for loop generates the list of data files that I need to copy.
  the DBMS_FILE_TRANSFER. PUT_FILE copy one after one.
  
  Can you suggest how can I changed the plsql block below to create
  and present in parallel a job for each data file?
  
  Thank you.

  Hello

  I'm happy that it worked. Don't worry, in this case, this setting is not necessary

  Kind regards
