• Management of transactions

  Hello
  
  
  I have my doubts after reading the book of concepts of Oracle 10 g 2.
  
  I had a doubt in the management of transactions.
  
  
  "Say the database is sweet started and the user is a ' insert into EMP values" transaction.
  
  Process:
  
  (1) process server first attempts to find the data in DB pads.
  (2) not find because the database is started first. Then he reads the data file and places it in the LRU (database buffers) list.
  (3) written and redo entry in journal editor. 'remove the EMP online with the values' (I am in doubt if this is correct.) Please correct me)
  (4) we will tell user is committed now.
  (5) LGWR writes the data as a commit. Written data are committed to restore the log files to redo buffers.
  (6) should not wait for database buffers to write since we have consistent data in redo files.
  
  
  My doubt is that lGWR writes. Documentation, says he writes redo entries. Redo entries means the ' insert ' or 'delete statement.

  Hello

  In your case.

  Redo entries means "insert a statement."
  cancel the means of entries to 'delete the statement '.

• Manage the CRUD operations in unique transactions

  Hello

  How can I manage the CRUD operations in single transactions using JTA? While each a separate transaction operations will not be created? Please provide examples for this topic.

  Thank you.

  Hello

  Yes, the transaction manager is implemented through the Java API of the Transaction (JTA).

  The JTA includes two main interfaces for the management of transactions, javax.transaction.TransactionManager and javax.transaction.UserTransaction.

  See: transaction manager

  And to use transactionManager, you need to inject exactly as you said.

  Why do a bit better with Demarcation of Transaction:

  TransactionDemarcation td = new TransactionDemarcation();
  boolean rollback = true;
  try {
    td.begin(getTransactionManager());
   // all changes in items of repository
    rollback = false;
  } catch (TransactionDemarcationException e) {
    throw e;
  } finally {
    try {
    td.end(rollback);
    } catch (TransactionDemarcationException tde) {
    throw tde;
    }
  }
  

• Unable to set up the transaction manager

  I'm unable to set up the transaction manager. I am using weblogic.
  
  I created component TransactionManager and placed it to atg/dynamo/service/transaction. This is what I did.
  #/ atg/dynamo/service/transaction/TransactionManager
  $class = atg.nucleus.StaticMethodReference
  staticMethodName = weblogic.transaction.TxHelper.getTransactionManager
  
  I am getting error on next console:
  atg.dtm.TransactionDemarcationException: the transactionManager has not been specified in the call to begin(). Delimitation of the transaction fails.
  
  getTransactionManager() is null begin the method of TransactionDemarcation:
  
  TD. Begin (getTransactionManager (), 3);
  
  I tried with mysql and oracle, that the two databases.
  
  Any help?
  
  Thanks in advance,

  I have it. It was a stupid mistake. Instead of getting the component via the name of will that I tried to get OOTB component by using the new operator, so in order to subject current OOTB, Manager of transactions was been set to null values.

  Sorry Shaik, my bad!

  Appreciate the answers!

• Programmatically change the taskflow transaction behavior

  Hi all
  
  
  Is it possible to programmatically change the transaction behavior taskflow "Always start a new transaction" to "reuse the existing Transaction? I have a taskflow which must be consumed by different teams and some teams want post me the transaction independent of their own, while others would like to indulge my changes with them once I returned from my taskflow control appellant taskflow.
  
  Any suggestions on this?
  
  Thank you
  Srini

  I think that my answer was based on the semantics of your question. You have asked to change transaction option behavior programmatically separate to change the flow of task transaction behavior. Indeed the messages of Jobinesh provide such a mechanism and of course be too aware of the scope of data control.

  Make one step back however, why don't the existing Transaction to use option if Possible do not work for you? If the appellant wants to that you have a remote, they just wrap your call in one always start new Transaction BTF. This way, you don't have to worry about the behavior of the transaction, it is the appellant as it should.

• JMS sender with container managed transaction ejb3

  Hi all
  
  I refer to the following link http://download.oracle.com/docs/cd/E11035_01/wls100/jms/trans.html#wp1035937
  
  I found that JTA support JMS.
  
  But I have no ' to use JTA explicitly, I want to use the container to manage the transaction. for example. within the ejb3 stateless session bean.
  
  support JMS?
  
  With respect,
  WP

  Hello

  Yes, WebLogic JMS supports JTA (alias XA, a.k.a global) transactions such as container managed transactions. There are two conditions for CMTs on SSB:

  (1) use a parameter descriptor XML or EJB annotation to turn on CMT for SSB

  (2) use a WebLogic JMS connection factory that is configured to have 'global transactions (XA) enabled.

  And I usually recommend also:

  (3) consider using a JEE 'res-ref' for the connection factory to allow reunification of the JMS resources. See "Enhanced Support for using WebLogic JMS with EJB and servlet ' (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13727/j2ee.htm#g1329180) and the 'integration JMS remote suppliers' FAQ (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13727/interop.htm#JMSPG553).

  (4) avoid using a BSN to receive messages. BMD is designed to process incoming messages.

  It is also possible to have WebLogic automatically registered foreign suppliers (non-WebLogic) in WebLogic transactions. See the 'integration JMS remote suppliers' FAQ for more details (http://download.oracle.com/docs/cd/E14571_01/web.1111/e13727/interop.htm#JMSPG553).

• How to manage transactions during the different caches

  I found in the document, we could use TransactionMap to manage a transaction for a cache. For example, we put all the books in a cache named book_cache.
  But I wonder if we can manage a transaction on different caches. For example, we have all the books in book_cache and all of the editor, then put in publisher_cache. Then we consider change a book and change a Publisher as a unit of work. How to handle this?
  
  Thanks in advance.

  Hi Ramon

  You can use key association to ensure that a set of cache entries related is included in a partition one cache. This is what we call data affinity.

  See http://coherence.oracle.com/display/COH35UG/Data+Affinity

  According to John, which will guarantee of atomicity. Here is quote from John from a previous post.

  "The only way to ensure atomicity must ensure that a transaction cover partitions. You could watch association key to ensure that related data resides in the same partition. »

• Transaction and transaction AppModule Taskflow both are the same or not?

  Transaction and transaction AppModule Taskflow both are the same or not? or what are the differences between these two operations.

  Workflow transaction is different from the transaction data base (I mean the transaction returned by am.getDBTransaction ()). Each workflow is associated with a data control framework. A data control framework is the container that is associated with a workflow that contains several instances of data control. The ADF Model layer exposes the DataControlFrame interface to manage a transaction involving data controls in the framework. DataControlFrame interface exposes methods such as:

  • beginTransaction()
  • Commit()
  • Rollback()
  • createSavepoint () - Note that it is the backup point maintained by the controller of Oracle ADF and it is similar to the point of backup of database
  • isTransactionDirty()

  Task Transaction flow

  There are four transaction options that a stubborn workflow can use (notice that unbounded flow task does not support transactions):

  1. No Transaction controller: delimited task called flow does not participate in the management of transactions any controller ADF.
  2. Always Begin new Transaction: A new transaction begins when the stubborn workflow is entered, regardless of whether a transaction is in progress. The new transaction ends when the stubborn workflow stops.
  3. Always Use Existing Transaction: When it is called, the stubborn workflow participate in an existing transaction already underway.
  4. Use the existing if Possible Transaction: when it is called, the stubborn workflow is involved either in an existing transaction if there is, or starts a new transaction when the entrance to the stubborn workflow, if one does not exist.

• Onload event management to add business logic to the JSF page in ADF

  I want to know how to handle the onload event so that add us business logic once a view is loaded.
  In short, that's what I want to achieve-
  I have an entity object that I show as editable ADF table. Once the page is loaded and I want the table to show at least 4 tiers bit regardless of the number of lines now exist in the database table. For example, if the database table has 2 entries then table ADF should show these 2 rows and 2 additional lines in the table of the ADF. And if the database table has 6 ranks, it should show 6-row table of the ADF. How to programmatically manage this feature. What functions and methods, I need to replace or add. Any help is appreciated.
  
  Thank you.

• Transaction validation error in Stored Proc call - prev solns does not

  Hi all
  
  Our process calls a DB adapter to retrieve the answer from the table to our application via a call to stored procedure, but in the face of the slot issue. Its a synchronous process. The stored procedure is present inside the package and call the stored procedure using this Package.
  
  What we did is created a DB of type XA data source and tried to call the stored Proc but it appeared a problem "ORA-24777: the use of the non-migratable unauthorized link database ' and therefore, according to this thread DB links in stored proc call into the adapter DB 11 G SOA , we have changed the type of non - XA data source.
  
  While we do this, we could see that stored procedure is called and the answer is not in the payload to answer within the track of the flow. But the instance is get failed and the error is "error committing transaction:; nested exception is: javax.transaction.xa.XAException: JDBC driver does not support the XA, so may not be a participant in the validation in two phases. To force this participation, set the attribute GlobalTransactionsProtocol (recommended) LoggingLastResource or EmulateTwoPhaseCommit for the Data Source. »
  
  We have tried properties to support overall transaction as imitate a validation phase, two phase commit and logging last resource but error remains the same.
  
  Database from where we get the answer is a version of "Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production". The link of database error is due even if we connect to the Oracle database?
  
  Please could you tell me solutions for this problem.
  
  Thanks in advance.

  You use a Non - XA because it means (among others) that the issue of validation can be handle by the DB as well.
  The property to imitate two Phase imitating the transaction XA in this way, it allows you to manage a transaction local db.
  You can stay with XA connection, but then you have to use 'pragma AUTONOMOUS_TRANSACTION' in your procedure.

• Jolt transaction to Tuxedo services - required XA?

  Dear friends (especially Todd little).
  
  Sorry, but the Jolt and Tuxedo documentation is really low (to say the least) with regard to managing the transactions of jolt.
  
  I would like to ask your help kind to answer the simplest question in the world:
  
  I have two Tuxedo services each doing some updates to a database. Working against the same DB (DB only contact, no multiple DBs) and within the same instance of Tuxedo in production.
  
  I wish that both services to do their updates in a transactional manner when it is called shake (with SessionPool transactional).
  
  Do I need both of these services to run with XA resources for this, or not?
  
  My natural expectation (from global experience JEE) is that both services would be affected (by the container, in our case Smoking) with the same DB connection to perform their updates, that is why when the connection is restored (due to failure in a single service), all update (from all the previous services) are cancelled.
  
  And I would expect Tuxedo to manage this, all services, called the same session transactional Jolt would share the same DB connection (just like it happens with any JEE server or Weblogic when an XA transaction is running).
  
  I would expect not necessary to configure (and worse, for use in production) an XA resource for the implementation of the (simple) company.
  It's like buying the cow for a glass of milk...
  
  Could you please draw on it?
  
  Kind regards.

  Hello

  "Connection pooling" Tuxedo is very different from the JEE environment. Each server connects to the database independent of every other server. Linking strategies are controlled by the OPENINFO chain. So if two different groups of Tuxedo servers access databases the same or different, an XA transaction is necessary because there are two or more database connections. This operation can be started by tremor, started by Tuxedo service called shake, or TRANSCENDING. Regardless of how the transaction is started, the local transaction to Tuxedo, i.e., it will not involve transaction manager of containers of the tremor as Quake or JTA transactions are always delegated to managed by the JSH. If all services that are called are in one group of Tuxedo, Tuxdeo will be the collapse of the tree of the transaction to a single resource manager and perform a phase commit optimization.

  I hope that the above, your questions.

  Kind regards

• Apple has access to my bank accounts?

  Hello

  I registered my Amex card with iPay. Now, every time I use my Amex card by sliding it to the point of sale, I get notification from my iPhone. This means that Apple knows all my transactions? How does he know that I use my card?

  Thank you.

  Because pay Apple manages the transaction, that's why you receive the notification. When you use Apple pay, they manage the transaction and protect your real credit card the dealer number. What they see is the number of device provided by Apple pay.

• Time of response and visits the URL table

  Hello

  We want to capture the URL request hits and their average response time Foglight.  I also want to know how an alert if the successes are above the threshold.

  Is it possible to do using Foglight? If Yes please let me know the steps to do it?

  Thank you

  Sure.

  The entire process is described in the documentation.

  Basically, you will need to download the support link cartridge

  

  Download the Foglight Management Server web console > administration > cartridges > inventory

  

  Deploy on the fglam from which you want to run the agent (and requests).

  

  Create an agent.

  

  Configure the basic properties (it's optional, I saw people wearing at least the location alias they wanted a good logical name) and activation of the agent.

  

  You can repeat this step and create several different fglams agents that run in different places (make sure that you give them good logical names in the aliases).

  Then go to the webmonitor > directors home and click on manage them transactions

  

  Click the Add button to add transactions, you can specify the names of transaction, the webmonitor to only get the page header or clarify some should define the content. Notice the bottom of the pop up where you choose where transactions are played and notice the options button advanced option

  

  The advanced settings allows you to change the default thresholds for response time so that specify proxy (note that if you use a proxy, you will need set the credentials).

  

  The result will be visible in the performance Explorer.

  

  Note You can also press the button "Explore" to see the forest-downs

  I hope this helps.
