Table of $ OBJ is locked during the query

• Locking during the generation and the online option to avoid problems

  Hi Experts,
  
  In our suite of applications, schemas are shared among several applications, and even when there is a deployment of an application, the other application remains upward. In this process, we are facing problems of locking. For example, when creating indexes, I get the error "resource busy and acquired with no expectations. This post is specific to this point on error when creating index (change the design of the app etc is out of reach for me currently).
  
  I was checking the "online" option of create index and I was wondering if that helps. It looks promising for me. When we have large tables (50 million more and creating indexes on them takes about 5 minutes and at the same time we have another app doing short transactions - who commit in 5 seconds, then creating index 'with the option' can help - is what I was asking.)
  
  Here is an example of what I've tried:

  -- first create a table with a few million rows:
  
  SET SERVEROUTPUT ON
  
  DECLARE
    v_sql VARCHAR2 (200);
  BEGIN
    v_sql := 'create table test as select * from dba_objects';
  
    EXECUTE IMMEDIATE v_sql;
  
    FOR i IN 1 .. 5
    LOOP
    v_sql := 'insert into test select * from test';
  
    EXECUTE IMMEDIATE v_sql;
  
    COMMIT;
    END LOOP;
  END;
  /
  
  --Now in session 1:
  ---------
  
  
  create index ti1 on test(OWNER,OBJECT_NAME,SUBOBJECT_NAME,OBJECT_ID,DATA_OBJECT_ID,OBJECT_TYPE,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS,TEMPORARY,GENERATED,SECONDARY,NAMESPACE)
  online;
  
  session 2:
  ------------
  DELETE FROM TEST WHERE ROWNUM<1000;
  
  commit;
  
  DELETE FROM TEST WHERE ROWNUM<40200;
  rollback;
  
  --etc.
  

  
  I find that deletions, etc. in the second session is done (they follow by commit and they take a few seconds) with this option 'create an index online '. The option 'create index' is also no error with the error ORA-«resource busy...» ». So what a better way to create indexes to avoid locking issues? Note that is is very good for us to have the creation of index take more time for what's important is that they are not lacking in critical production deployments.
  
  Are there other possible implications (-except that it takes more time to create the index with the option 'online'), that one should be aware of? Any known issues or is there any other glitches with the creation of online index?
  
  I will be grateful for any views on that.
  
  

  What is your version of DB full?

  In our suite of applications, schemas are shared among several applications, and even when there is a deployment of an application, the other application remains upward. In this process, we are facing problems of locking. For example, when creating indexes, I get the error "resource busy and acquired with no expectations.

  OK-, this exception is not surprising. To create or rebuild an index, Oracle has a lock on the base table. He can't do that if other users perform DML on the table - it must wait.

  And before 11 g ANY other session that then tries to perform DML on the base table that oracle wait will also block.

  I was checking the "online" option of create index and I was wondering if that helps.

  Well, if you do not use the clause of 'ONLINE' you must do that maintenance CONNECTION or you now cause other sessions cling while creating/reconstruction is made;

  It looks promising for me. When we have large tables (50 million more and creating indexes on them takes about 5 minutes and at the same time we have another app doing short transactions - who commit in 5 seconds, then creating index 'with the option' can help - is what I was asking.)

  Yes - it should help. But he cannot eliminate the problem entirely.

• Coordination of detail during the query mode

  Forms 11g

  I have a relationship of the master / detail, details of autoquery. the two blocks are displayed several records. I want to show a flag value (and the color attribute) next to the master if he got to the detail records.

  To do this, I coded it in the post of the block in detail, because I wanted to avoid the questioning of the secondary table twice (one in the master post-requete and secondly in the population of retail block).

  When running I run the query for the master, but the detail does not seem to be queried for all the record questioned captain. My tracking after request works only for the selected record of the master.

  Is this normal? Is coordination suspended unless you are in NORMAL mode?

  Yes, it comes to the features of normal forms.  To highlight each master record based on if are detail records, you must query the table Details in the trigger of the Master post-requete.

  You could simplify this by creating a database function that returns a TRUE/FALSE value rather than to perform a COUNT (*) SELECT your trigger after request.  Then your trigger after query is simply:

  BEGIN
    If ( YOUR_DB_FUNCTION = TRUE ) THEN
       Set_Item_Instance_Propety('YOUR_BLOCK',CURRENT_RECORD,PROPERTY,PROPERTY_VALUE);
    END IF;
  END;

• How can I filter a table of data control without entering the query

  I have a table from a WSDL-based web service data control.
  
  I want to filter the table without input query in the filter text box. Without text filter box, each could filter the table with a query hardcoded internally.
  For example, when the user menu button click and then it filters the table where type = '1' and B menu button filters the table by type = '2' and C menu button filters the table by type =' "."
  
  How can I filter the table without entering the query?
  
  Could someone point me to a solution please.
  
  Thank you.

  Hello

  When you have created the table, have you tried selecting the option "filter". Select the table, and access the property of m.. In the toolbar of the Properties Inspector, there is an icon to change the configuration. His fields of filter adding filter for the user to search in.

  Option 2: Data from the Web Service are actually held in iterators. If you want to filter the Web service request, I wouldn't use the WS domain controller but a proxy of JAX - WS in a POJO to recover data from the WS. Then the data control created from the POJO. You might have a method exposed on the POJO which allows you to filter the data internally that is held

  Look for the grant on the table. He must be given a ROLE and if so, then, you must have direct subsidies on the table to use only it in PL/SQL.

• FRM - 40212 / FRM - 40222 error on a radio during the query group

  Hi all
  
  This is my first post, so please bear with me if I did not provide enough information or am not clear at all.
  
  I use Forms Builder (Web) on a 10g database. I have a number of databases and elements non-base of data as part of a block of data.
  My problem is that when I enter a value in a field and click the query button, I have an invalid value FRM-40212 for error field on my radio group (section disabled, non-base of data, which is populated by programming in the triggers of post requests and amended list only). When I click ok, I get an error of FRM-40222 disabled point Validation failure on the same radio group.
  
  This does not happen if I click on the button "Enter the query" before you enter values in the fields, but I don't want my users to encounter this error if they try to interrogate without clicking "Enter the query" first.
  
  I would like to know why exactly this error happens - what it means?
  I read in other forums that setting the required article property to false solves this problem. But how can I do this with a group of radio buttons? And if it is not possible, anyone have any suggestions for other workaround solutions?
  
  Thanks in advance,
  
  Abigail

  Hello

  You can avoid this by defining "Mapping of other values" to a fo value of radio buttons. As if you need to radio radio1 and radio2 associated group R1 radio button, then set the option buttons the initial value of this property to 'Mapping of other values' radio button R1. You will not see this error.

  This error occurs because as your loading a screen without assigning a value to the option button.

  If this helps brand question as answer or useful.

  Federico,

  to do this, replace the queryListener one leave this point of a bean method. In this method, you run the processQuery by default and after that set the attribute to disclose the af:query component to false and ppr.

  {} public void processQuery (QueryEvent queryEvent)

  The generated QueryListener replaced by this method

  #{bindings. MyAllCriteriaQuery.processQuery}

  QueryDescriptor qdes = queryEvent.getDescriptor ();

  print or save the view criteria

  System.out.println ("NAME" + qdes.getName ());

  appeal by default query event

  {invokeQueryEventMethodExpression ("#{bindings.", QueryEvent "}") MyAllCriteriaQuery.processQuery};

  Object UIComponent = queryEvent.getSource () (UIComponent);

  Riq RichQuery = object (RichQuery);

  riq.setDisclosed (false);

  AdfFacesContext.getCurrentInstance () .addPartialTarget (riq);

  }

  Private Sub (string expression, QueryEvent queryEvent) invokeQueryEventMethodExpression {}

• Are tables autom. (if any) created during the import with impdp.exe?

  Just another question regarding the process of impdp.exe.
  
  Suppose that a table is dropped after the previous export operation (expdp.exe) (for the full database)
  Now I perform an import operation (impdp.exe).
  This table is automatically created again?
  
  What about users (patterns)? They are automatically created if they are in the dumpfile, but

  schemas will be created automatically only when you import lots.
  tables will be created either you do complete / schema / table level import.

• Extend the VO - need to change the query of VO - screen is off

  {Re-post the message in this forum (thanks to John Stegeman to lead me here...)   {Posted: August 28, 2009 04:27}
  
  Dear all,
  
  Thanks to this great body of knowledge, I ask my questions.
  
  I need to extend a VO to display the name of the country.
  The column is not in the VO. So, I need to get another table: FndTerritories
  
  I want to change the query, but the request frame is turned off (in the wizard the View - step 5 of 6 - Generated statement object substitution)
  
  Could you be it someone please let me know: how to change the application of the VO in this case?
  
  OR is there another solution for such cases, to maintain development standards
  
  Thank you very much
  
  Kind regards

  Hello

  I think that's when you just have to add an attribute, you should not click the expert mode checkbox... make use of
  Mix and add the button.

  But when you need to modify the query, and then we want to use to modify the query window...

• During the ETG Table lock

  Hello

  I want to clone a table in our database. Version: 11.2.0.4

  
  Test case:

  CREATE TABLE test_1

  (IDENTIFICATION NUMBER)

  /

  INSERT INTO test_1 (id) values (5);

  COMMIT;

  Now-> I want to start cloning from the table. BUT! After cloning, I must write off line-counts of the original and cloned table. (simple audit)

  To avoid any DML operation during cloning I lock the table in exclusive mode.

  Test_1 in MODE EXCLUSIVE TABLE LOCK.

  -> Now I start the operation of the ETG

  -> DDL's implicit VALIDATION here

  CREATE TABLE test_clone

  AS

  SELECT * from test_1

  /

  -> DDL's implicit VALIDATION here too

  -> Here would be County-parts to start... (The Original County and County of Clone)

  Problem: My DDL statement makes two implicit commits-> first before the DDL and second after the DDL.

  So, in this case the lock on the original table will be released before cloning could begin. --> During a long race THAT DEC can other data manipulations arrive on the original of another session table.

  And in this case if I count the original and the clone table lines I can get a different result.

  Do you know a solution for this?

  -> I can't start a procedure or a second session-> This cloning is done in a DB-Patch which we deliver to DBA.

  -> I can only run an anonymous pl/sql block

  -> In fact, I don't want to use the INSERT INTO (append)... because an ETG is faster and I want to know if there could be a solution for this problem with the DDL.

  I thought to create a trigger on the original table that fires if a DML arrived-> but what happens if a DBA ends the script... then this trigger there. So, I would avoid this change in structure.

  How I could lock the original table so that I can run a DDL in the same session after it without to release the lock on the original table? -> I don't think that would work, but you may know...

  Thanks in advance!

  In fact, I wanted to know if if it was very important how it could be solved. -> In my case, it would have been good to get to know a solution said that maybe I don't know yet.

  A better solution IMHO and the most common way to do it is just put the table in READ ONLY mode.

  ALTER TABLE myTable READ ONLY

  ... do the ETG

  In general, there are many more controls to perform AFTER the operation than just the count of lines. These controls can should be performed by multiple sessions/users for an autonomous transaction will not help you here.

  Reading using only keep data available without him to be changed. You can then rename the original table to keep data online for a period of time or to allow time for it to be saved.

  Although your optimizer_mode is choosing, it seems that there are no statistics collected on ehgeoconstru. The absence of estimated costs and estimated row counts of each of the stages of the plan and the "Note: optimization based on rules" at the end of these two plans would tend to confirm this.

  Optimizer_mode choose means that if statistics are collected then it will use the CBO, but if no statistic is present in any of the tables in the query, the optimizer to rule will be used. The RBO tends to be happy in the best of the index case. I guess the index ehgeoconstru_VSN contextversion as the main column and also includes the date of birth.

  You can either gather statistics on the table (if all other tables have statistics) using dbms_stats.gather_table_stats, or suggest the query to use a full scan instead of index. Another solution would be to apply a function or an operation against the contextversion to prevent the use of the index. something like this:

  SELECT COUNT(*)
  FROM ehgeoconstru  ec
  WHERE ec.type='BAR' and
        ec.contextVersion||'' = 'REALWORLD'
        ec.birthDate <= TO_DATE('2009-10-06 11:52:12', 'YYYY-MM-DD HH24:MI:SS') and
        deathdate is null and
        SUBSTR(ec.strgfd, 1, LENGTH('[CIMText')) <> '[CIMText'
  

  or maybe UPPER (ec.contextVersion) so that would not change the rows returned.
