Transaction to Toplink

• 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

• development of controller of the outer transaction on Weblogic 11 9/Toplink

  Hi all
  
  I was going through many references on docs and would just confirm that I'm doing this right. Could you please tell me if this is a good way to open the external controller of Transaction?
  
  Project = new TOPProject() / / we export our workbench for java class
  ......
  DatabaseLogin login = project.getLogin ();
  ......
  login.shouldUseExternalConnectionPooling ();
  login.shouldUseExternalTransactionController ();
  ...
  JNDIConnector jndiConnector = new JNDIConnector (LookupHelper.createBasicContext (), datasourceJNDIName); source of data is transactional
  login.setConnector (jndiConnector);
  
  session = project.createServerSession ();
  session.setServerPlatform (new WebLogic_9_Platform (session));
  
  WebLogicTransactionController wlsTC = new WebLogicTransactionController();
  wlsTC.setTransactionManager (TransactionHelper.getTransactionHelper () .getTransactionManager ());
  session.setExternalTransactionController (wlsTC);
  
  
  
  Thanks in advance

  Your question is,

  It is false, that the methods get/test methods not setting
  ......
  login.shouldUseExternalConnectionPooling ();
  login.shouldUseExternalTransactionController ();

  use,
  login.setUsesExternalConnectionPooling (true);

• TopLink recording does not

  We use TopLink 9.0.3.7 in our Java application. Recently, I added two new tables, in that I try to save. I compare it to some tables similar to record properly and everything seems to be the same. I compared the descriptors created by TopLink Mappling WorkBench 9.0.3.5 and they appear even too.

  Our class Action

  submissionDao.transaction(sessionInfo.getClerkReviewSubmission(),
  new TransactionBlock<ClerkReviewSubmission>() {
  public void merge(ClerkReviewSubmission detached,
  ClerkReviewSubmission managed) {

  ClerkReviewTask task = mergeTask(new ClerkReviewTask(),
  myForm);
  for(ClerkReviewCase crCase: sessionInfo.getClerkReviewSubmission().getCases()){
  createCaseTask(crCase, task);
  }
  }
  });

  private final ClerkReviewCaseTask createCaseTask(ClerkReviewCase crCase,
  ClerkReviewTask task) {
  ClerkReviewCaseTask caseTask = new ClerkReviewCaseTask();
  caseTask.setClerkReviewCase(crCase);
  caseTask.setTask(task);
  crCase.getCaseTasks().add(caseTask);
  task.getCaseTasks().add(caseTask);
  return caseTask;
  }

  Our class of BaseDAO

  public T transaction(T detached, TransactionBlock transactionBlock) throws BadDBConnection {
  Session session = centralSourceInjector.inject();
  UnitOfWork uow = session.acquireUnitOfWork();

  try {
  T managed = (T)uow.registerObject((T) detached);
  transactionBlock.merge(detached, managed);

  uow.commit();
  session.refreshObject(detached);
  return managed;
  } catch(OptimisticLockException ole){
  uow.rollbackTransaction();
  throw ole;
  } finally {
  uow.release();
  }
}

  When I debug I'm arrive in the class of BaseDAO and I see in the newspapers are:

  UnitOfWork (3889394) - start work unit are committed

  ClientSession (5022219) - connection (7034305) - begin transaction

  ClientSession (5022219) - connection (7034305) - transaction validation

  UnitOfWork (3889394) - end of work unit are committed

  UnitOfWork (3889394) - unit of induction of labour

  Any Suggestions or advice would be appreciated.

  A co-worker has looked at my code and suggested I add an additional line and it fixed the problem. It suggested that a small change in my Action class:

  submissionDao.transaction(sessionInfo.getClerkReviewSubmission(), 
       new TransactionBlock() { 
            public void merge(ClerkReviewSubmission detached, 
                 ClerkReviewSubmission managed) { 
              ClerkReviewTask task = mergeTask(new ClerkReviewTask(), myForm); 
              for (ClerkReviewCase crCase : sessionInfo .getClerkReviewSubmission().getCases()) { 
                 ClerkReviewCase crCase2 = managed.findCase(crCase .getIcisCaseId()); 
                 createCaseTask(crCase2, task); 
               } 
            } 
       });
  }

• TopLink and v11.2.0.2.0 JDBC driver

  When the JDBC Oracle v11.2.0.2.0 driver is used with TopLink I get an error - java.lang.ClassCastException: incompatible com.ibm.ws.rsadapter.jdbc.WSJdbcConnection with oracle.jdbc.OracleConnection to oracle.sql.TIMESTAMPTZ.timestampValue(TIMESTAMPTZ.java:879)
  
  I noticed that this happens when a descriptor uses the Timestamp locking and TopLink emits the SYSTIMESTAMP SELECT FROM DUAL instruction for the timestamp.
  
  The unit test is a simple object of a descriptor using the timestamp locking.
  
  The same test with the v 11106 Driver works fine.
  
  Thanks for the help.

  Hi, you have a different problem.

  work was done to address the logic of TIMESTAMPTZ recovery in 11.1.1.4.0 code. The problem is that the JDBC connection, passed to the TIMESTAMPTZ is set to zero, and the pilot is to launch a NPE. This was done in response to versions more recent/future of the driver not being able to return a TIMESTAMPTZ without a valid connection.

  This should be resolved for you using TopLink 11.1.1.4.0 or later version (the version of your TL unspecified in this forum).

• JDBC + PL/SQL vs TopLink provided speed?

  Obviously topLink will save a lot of time of software development. But I have no doubt that it will create an overload during the data recovery when you use links.
  
  We use EJB + Servlet + JSP and usually what we do is extracting data using jdbc and assigning values to a java bean and taking them to the Servlet layer. But when you use a framework entity he made himself to the developer. Therefore, it is very difficult for me to decide whether to go to topLinks or hibernation or stay with jdbc.
  
  Please help me to make the wisest decision!
  
  Thank you!

  Hello
  It is always advisable to use an ORM framework instead of using JDBC in a J2EE application. Here are the benefits if you consider TopLink for your project

  1. declarative development of interaction of the database/model. At the top level includes queries, transactions, locking, mapping, etc.
  2 separates the code type of SQL dependencies or the dependence of the database.
  3 summarized the low level of encryption required for the database and makes development faster and easier.
  4. generated code is always scalable, portable and robust.
  5. purpose of Table mapping is done very effectively and is not coupled with the code.
  6. If the entity manager is used with EJB, container will inject the ther of persistence of any resource context, environment, services of middleware for the peristence mechanism is ready available.

  Hope the above helps you make the decision.
  Kind regards
  Vinay

• Get a new object saved in the cache to Toplink

  Hello
  
  I use Toplink 11 g Release 1 (11.1.1.1.0) on JDeveloper 11.1.1.1.0, driver JDBC 11.1.0.7.0.
  
  I have a table named tblWords with the following columns (id, text) and a unique constraint on the text.
  I created a sequence and a trigger on the table then when Toplink inserts a new Word it inserts only the text and returns the ID of the trigger.
  
  Everything I do to insert the word is:
  tblWords newWord = new tblWords();
  newWord.setText ("Test");
  m_uow.registerObject (newWord);
  
  Now I s'pose a list of words that may contain duplicates. I ask Toplink to see if a word was previously introduced by:
  Query ReadAllQuery = new ReadAllQuery (tblWords .class);
  Manufacturer the ExpressionBuilder = query.getExpressionBuilder ();
  query.setSelectionCriteria (builder.get("text").equal (parameter));
  
  Vector < tblWords > words = (vector < tblWords >) m_uow.executeQuery (query);
  
  If (words! = null & & words. size() > 0)
  return (words.get (0));
  on the other
  Returns a null value.
  
  It works very well if a word was already in the DB, but if the word list contains duplicates, the code returns null then registerObject will be called twice for the same text and a violation of uniqueness constraint is triggered when commit is called from Toplink calls INSERT tblWords (text) VALUES('Test') twice.
  
  How can I query the cache for a word that I just created using registerObject without committing?
  
  Thank you!

  You should check for duplicate before you create them. Anyway, you cannot always prevent violations of constraints, because when the two operations run at the same time you do not see that the other transaction creates a duplicate until it is committed.

  Same query with conform to the (recommended) active work unit you will return everything you have in the not yet committed UOW and what you have in DB. However, if you have auto RAS, and depending on which API you are using, the validation can be triggered before the query.

• JTA-data-source not RESOURCE_LOCAL-type of transaction and UserTransaction

  Hi all
  
  I'm curious of my way through an application that I help maintain. Some of the details of the implementation of puzzled me, and I could use a validation test. We use Toplink Essentials.
  
  For starters, the persistence.xml - the one and only - specifies a transaction type of RESOURCE_LOCAL. In addition, we have a non - JTA data source.
  
  My understanding is that because what precedes, we get an EntityManager via an EntityManagerFactory, there is a 1:1 correspondence between any given EntityManager and a persistence context (so we would better not more than one EM at a given time, or be very careful as to how we deal with several living at the same time) , and that we are required to use the EntityTransaction API to the demarcation of the transaction limits.
  
  Here's the thing: the app also has a semblance of a "long running operation. It is bounded in the code, through the use of JTA - raising a UserTransaction with JNDI and using begin(), commit() and rollback() on it as required.
  
  I might also add that from a functional point of view the application works obviously.
  
  My question is this: regardless of how the application has achieved its goal, that the JTA UserTransaction does exactly? I can almost see that he does nothing at all.
  
  Thank you
  Arved

  Correct, resouce_local means no JTA.

• Several weeks ago, Firefox displays a receipt for a transaction at Costco and become totally insensitive. He still goes there when opened.

  When you complete a transaction at the Costco Photo, my display reception and Firefox has become totally insensitive. He was waiting for something, and the led was "busy". He couldn't be stopped using the Tak Manager to complete the process. Therefore, whenever Firefox is opened, he went straight to this page and became unresponsive. I uninstalled Firefox and use another browser for several weeks, but when I reinstalled Firefox and its opening, the same reception screen appeared, the 'busy' circle and Firefox could only be stopped by the Task Manager. I erased some cache and browsing history, but nothing is. Any ideas?

  You all link shortcut on the desktop you? Use one of them. Or,
  If you have a Firefox icon in your taskbar, right click and select
  Open a new window.

  This add-on can stop these pages; disable the button Script {web link}
  The button reject Script resembles the letter "M" and the title is the least Script, drag-and - déposer the button on a toolbar. If the button does not appear while nothing works, except rules of plug-ins.

  Type of topic: customization< enter > in the address bar.
  In the new window, locate the icon of the button Script reject. When you find
  it, hold down the left button on it and move it to where you want it to be.
  I suggest just to the right of the address bar.

  If your browser is locked up, just press the icon and close this tab.

• When Mozilla online banking does not permit me to see the details of a transaction so that Internet Explorer will allow it. Mozilla has been done, but not now.

  I do my banking online with Bank of America, usually using Mozilla Firefox. Recently I noticed when I clicked on a banking transaction to see the "details" or print only this particular operation, it only allows me to see the details.

  Previously, whenever I clicked on a transaction, to see the image of a control I wrote for example, he always brought to the top of an image of the cheque. Now, he won't do it.

  If I use Internet Explorer, I can click on a specific bank transaction and see the details, exactly how I used to be able to do this with Mozilla Firefox.

  Therefore, the problem is with Mozilla and not the website of Bank of America, right?

  The suggestion to disable Adblock 2.4... "worked. "He solved my problem... Thanks a lot guys... problem solved with a click of the mouse. I can't tell you how much I appreciate the help... the technical support worked! Problem solved!

• BofA transaction description links do not work in Firefox...

  Starting with 21 Firefox and now with Firefox 22.0, I can no longer edit the descriptions of the transactions in the current account Bank of America Online. By clicking on the links has no effect. This function worked in previous versions of Firefox, and it works in the latest version of Internet Explorer. Technical support of Bank of America blame Firefox for incompatibility.
  Any suggestions will be appreciated.

  Thank you. I discovered the whitelist to Ghostery option and now have the BofA site whitelisting. I have also informed the problem Ghostery.

• Transaction declined and last four numbers on the sheet, not the same as the card is used.

  Transaction declined and last four numbers on the sheet, not the same as the card is in my wallet.

  Hello

  The latest figures, rare are the last four digits of your account number of device, not the last four digits of your credit card.

  To see these numbers on your iPhone, go to: portfolio > tap to select this card > press the 'i' icon (bottom-right) > under the heading card, information the last few digits of your card number and your account number of the device.

  The account number of the device is related to the unique combination of your credit card, pay more the device on which it has been added to Apple (IE an iPhone, iPad, or Apple Watch).

• PIN denied but cc transaction work

  If I try to use my debit card to the flow on a transaction to pay Apple, I get refused to enter a wrong PIN. It works like a credit card. I wonder if I did something to the configuration that makes it this way.

  Hello

  When you use Apple pay in stores, if you are offered the choice of credit or debit card on the payment terminal, Apple recommends you always choose credit - regardless of the type of credit card you are using via Apple pay.

  Choose the debit may not always work with success - for example, with some former payment terminals and/or back-end systems.

• Do all my purchased apps and transactions, transfer again ID after changing Apple ID?

  Hello

  I use my custom as my apple ID email address, but this year I decided to change my domain and ID.

  I've seen this before: https://support.apple.com/en-us/ht202667

  My question is:

  Do all my purchased apps and transactions, transfer again ID after changing Apple ID?

  Concerning

  Change the primary e-mail address on an account should not lose any content of the accounts - after changing your id: what to do when you have changed your Apple ID email address or password - Apple support (or disconnection across before changing preference and return with the updated later version)

  But if you are referring specifically to be able to redownload apps etc, they (and albums of music, etc.) could be removed from the Bank by the holder of the rights at any time, so you should not rely on the possibility of any element of the store to download again.

• I can't find my Apple Watch recent transactions

  I can't seem to find the recent purchases of my Apple Watch in the application portfolio to wither my iPhone 6 s more or my Apple Watch. I don't know if this is done intentionally or if I'm just incompetent. If this was done intentionally I would really like it appears in the application portfolio on the iPhone. It gives me no I don't want to use my Apple Watch for purchases, if I'm not actually that much, I spent.

  Hello

  It is not currently possible to view your transaction history pay Apple on Apple Watch.

  If the same payment card has also been added to pay Apple to your iPhone, then it is possible that payments made via this card on your watch can be included in the transaction history within the portfolio on your iPhone app.

  On your iPhone, the information in the portfolio include:

  • Last trade: shown below a map after tapping to select;
  • Latest 10 transactions: showed after type a card and then tapping on the icon info ('i' in the bottom right of the screen).

  Depending on your card issuer, these information may present:

  • Only transactions that were paid for the use of Apple pay on your iPhone.
  • All transactions made with your card / bank account (including the use of the card itself and use on all devices that use this card with Apple pay - including your watch).

  Otherwise the confirmation of transactions is provided timely via your card / bank statements (as it would if you were using the card directly).
