TopLink grid 11g: conversion of SQL queries to the filters of consistency

Similar Questions

• TopLink grid 11g and data consistency affinity

  I am to evaluate TopLink 11g grid that fits the coherence data grid. It seems to me when TopLink routes the request of coherence, it converts primary keys of database to be the key used in cache coherence. Is it possible to customize this conversion? The reason is that we want to use the affinity of data coherence function that requires a key to consistency to implement the method to return the keys association and lead conversion does not work for us.
  
  Thank you very much!

  I advise to use an IdClass incorporated into your JPA entities. You can then implement the necessary logic on the IdClass.

• TopLink grid 11g and transaction consistency

  During TopLink UOW is committed, only updated cache of transactional consistency? If the customer fails in the middle of TopLink UOW is committed, he let the situation that only partial objects are updated in the cache consistency? How TopLink manages the rollback to the cache consistency?

  In fact I miss - speak. In all cases TopLink will write only in cache coherence once all the writing to the database took place, although some entries are directed towards consistency. In the written case is directed to the consistency that we're investigating the TransactionCache to improve Atomic nature of the writing of coherence.

  If there is a failure of consistency after a base of data of TopLink writing consistency then native code will be necessary to force a reload of the entities that do not have consistent. The list of entities as part of the operation can be extracted from the UnitOfWork of the EntityManager

  Hello

  This is called a Pivot, and here's a way to do it:

  WITH got_display_yyyymm AS

  (

  SELECT TO_CHAR (ADD_MONTHS (SYSDATE-1)

  , "YYYYMM.

  ) AS YYYYMM

  OF the double

  )

  SELECT i.item_code

  i.item_name

  SUM (CASE

  WHEN i.transaction_yyyymm = d.yyyymm

  THEN i.qty_received

  END

  ) AS month_received

  SUM (CASE

  WHEN i.transaction_yyyymm = d.yyyymm

  THEN i.qty_sold

  END

  ) AS month_sold

  SUM (CASE

  WHEN SUBSTR (i.transaction_yyyymm, 1, 4)

  = SUBSTR (d.yyyymm, 1, 4)

  THEN i.qty_received

  END

  ) AS year_received

  SUM (CASE

  WHEN SUBSTR (i.transaction_yyyymm, 1, 4)

  = SUBSTR (d.yyyymm, 1, 4)

  THEN i.qty_sold

  END

  ) AS year_sold

  Item_sales I have

  CROSS JOIN got_display_yyyymm d

  I.item_code GROUP, i.item_name

  ORDER BY i.item_code, i.item_name

  ;

  If you would care to post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data, then I could test it.

  The subquery got_display_yyyymm digit which is the previous month; It is not to change anything from month to month.  If you run the query in October 2013, then YYYYMM Gets the value '201309'.  If you run it in January 2014, then YYYYMM will be '201312'.

  As posted, it will work in Oracle 9.1 or higher.  The SELECT... PIVOT function that was introduced in Oracle 11.1 would not help in this problem, so you do not miss anything using Oracle 10 in this case.

• How to tell the difference between access through JDBC and direct sql queries through server dimensions

  Hi all

  We use an Oracle 11 g server, the request is sent to the oracle database through different ways, one directly from the server of dimensions and is another method below

  • TDC customer creates a session in the api
  • session of the API sends a request to the application server
  • application server queries the database

  Of course, I see all the sql queries in the oracle database, but what I am interested in is now what queries go directly through the server dimensions and through the API. Please tell me how I can find this information.

  MACHINE, TERMINAL, PROGRAM, MODULE and CLIENT_INFO column in V$ SESSION could give you a clue.

• unnecessary SQL queries for ViewObject used in different tab

  In my application, I have a table A in the first tab and table B in the second tab.

  Sometimes when I work as a user with table B in the second tab, the ViewObjectA for table A is executed.

  Of course this ViewObjectA execution is absolutely useless, because I work in another tab and I don't don't even see table A.

  Unfortunately, the query takes a long time and it makes the application slower.

  Question: why the ADF runs the query for a table that is not visible and the user accesses not?

  Is it possible to prevent it?

  A note on the configuration that may be linked to the problem:

  The ViewObjectA has an implementation customized with debug messages (that's how I discovered the ViewObject is exectuted).

  Due to the limitation of the DB, I have configured my pool ApplicationModule instances of timeout after 120 idle seconds (because the DB does not like the many connections and long-term).

  I also found that after the expiry of the ApplicationModule, a new instance of ViewObjectA is created (Yes, it should according to the ViewObjectImpl API).

  It seems to me that the unnecessary ViewObjectA execution happens after this new creation of instance of ViewObjectA.

  Well, the execution of the query of a VO is part of the creation of a VO.

  You can try to adjust it for example, you add a where clause such as 1 = clause: bindVar' and init the bindVar to 0 so that the query is performed from the user interface (see JDeveloper: obstacle to the return of the games to outline on the loading of the page of VO using the binding variable |) JDev & amp; ADF Goodies).

• SQL queries that are stored in an array of sql pl

  I wonder if it is possible to have the SQL queries stored in a table in Oracle DB? I searched in google, but it seems that I'm bad key words to find the answer.
  
  I am trying to build sql queries in a certain place as a package or a procedure, and the logic would be completely out of the object sql queries in a table and the table to run each sql query in a loop.
  
  The version of oracle database is 11g.
  
  Thank you

• How to find the sql queries executed in one day with the sql and runtime text

  Hi Experts,

  Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

  Please reply urgent.

  Thanks in advance

  Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

  AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

  To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?

• Oracle 11g XE and SQL Developer

  Hello:

  Very new here.  I don't know where to post anything.  My apologies, but I'm all over the room.

  I installed 11g and downloaded SQL Developer (not even sure if it should be "installed" because it's just a zip file).

  In any case, on the SQL command line I get SYSTEM CONNECT, then my password.  I get the following error:

  ORA 12154: TNS could not resolve the connect identifier specified.

  Also, the "get started" link not working anymore.  Don't know what's happening, or if it is specific to my laptop.  I tried to connect two days without result.

• implicit conversion to sql

  Hi guys,.
  
  I have a question on how the oracle is posting implicit conversion in the following cases.
  
  I have a table: table1 with two columns: a number (10), b varchar2 (10). Both are indexed unique.
  
  
  If I have a SQL like this:

  select * from table1 where a = '99'

  the implicit conversion is performed on '99' and the final SQL will be something like:

  select * from table1 where a = to_number ('99')

  the same thing will happen with 'aaa' and I get an error. Please note that represents the column and the index will be used.
  
  If I have a sql like:

  select * from table1 where b = 99

  Note that b is the varchar2 column.
  the implicit conversion will be done on the column and the index will not be used

  select * from table1 where to_number (b) = 99

  THEN, forgetting for a moment that it is not OK to allow an implicit conversion, what are the rules that apply here? If the number, the conversion will be made on the value and varchar conversion will be performed on the column? What else?
  
  
  Thank you

• TopLink Grid: Create EntityManager fails when running on WebLogic

  Hello
  I am creating WebService that usus TopLink grid to access data. First of all I created simple stand-alone application with TopLink grid and all work very well. Then, I created WebService based on app created previously.
  When I try to run WebService deployed on WebLogic, I got error:
  "line Class ="Oracle.EclipseLink.Coherence.Integrated.config.GridCacheCustomizer"file =" GridCacheCustomizer.java "="30"method ="Customize. "
  java.lang.NoSuchMethodError org.eclipse.persistence.descriptors.ClassDescriptor.setFullyMergeEntity (Z) V
  It fails in the entityManagerFactory.createEntityManager () method.
  If deleted the eclipse configuration file - link.xml webservice customizer statement works. Maybe for server application needed some additional configuration or initialization?
  
  
  Thank you

  What is the version that you perform the deployment? The method not found was added in a later version, so it is probably there is a version mismatch where the Weblogic instance that is running and the version that you configured when running stand-alone. I think you need probalby use a version of Weblogic as 12.1.1 which comes with TopLink which includes EclipseLink 2.3.2 for this to work, or use a different version of EclipseLink which comes with the Weblogic instance that you are using.

• 11g connects to SQL server... character display problems

  Hi gurus,
  
  DB: 11.2
  OS: redhat 5.5
  
  There is a problem during display of character with sqlplus and even worse on TOAD, SQL Developer tool.
  
  There is a heterogeneous connection between 11g and ms sql serever. I use freedts, unixodbc and dg4odbc to connect.
  using tool isql... the select statement has been well formatted... See example |

  | USIM sales |
  | Charge accrued on debt Resprise

  BUT when I use sqlplus some characters are broken... Please see sample
  COST_NAME
  V e n s e t U S I M
  R e s p r e s i d e c h a r g e p r o v I s I o e n s e n s u r v e r
  a, c e n

  in other client tool for example, TOAD, the output is worse just see the only the first character of each line for example

  V
  R

  I tried the value for nls_language in french and English but do not solve the problem.
  
  anyone with a clue of what is wrong or a bug?... 1 million .thanks
