Implementing transactional messaging for .NET clients

 Create a transactional manager
  1. Initialize QAnywhere.

    This step is the same as in non-transactional messaging.

    using iAnywhere.QAnywhere.Client;
  2. Create a QATransactionalManager object.

    For example, to create a default QATransactionalManager object, invoke CreateQATransactionalManager:

    QATransactionalManager mgr = fact.CreateQATransactionalManager();  // no argument

    You can alternatively create a QATransactionalManager object that is customized using a properties file. The properties file is specified in the CreateQATransactionalManager method:

    QAManagerFactory fact = QAManagerFactory.Instance( "qa_mgr.props" );

    where qa_mgr.props is the name of the properties file that resides on the remote device.

  3. Initialize the QAManager object.

    mgr.Open();

You are now ready to send messages. The following procedure sends two messages in a single transaction.

 Send multiple messages in a single transaction
  1. Initialize message objects.

    QATextMessage msg_1;
    QATextMessage msg_2;
  2. Send the messages.

    The following code sends two messages in a single transaction:

         msg_1 = mgr.CreateTextMessage();
         msg_2 = mgr.CreateTextMessage();
         mgr.PutMessage( "jms_1\\queue_name", msg_1 );
         mgr.PutMessage( "jms_1\\queue_name", msg_2 );
         mgr.Commit();

    The Commit method commits the current transaction and begins a new transaction. This method commits all PutMessage() method and GetMessage() method invocations.

    Note

    The first transaction begins with the call to open method.
