Using arbitrary resources with JTA

由 荒凉一梦 提交于 2020-01-12 09:53:11
问题 Is it possible to make any type of custom resource transactioal with JTA? Let's assume a basic example and take a Folder creation that should be rolled back in case of an error. Can such custom resources be handled? 回答1: Yes. That resource needs to provide an implementation of XAResource, and an instance of that implementation needs to be enlisted with the transaction when the resource is used. The resource can get the current transaction from the transaction manager in order to carry out the

When should I use `REQUIRED` vs `NOT_SUPPORTED` as a the value of @TransactionAttribute for an MDB?

由 故事扮演 提交于 2020-01-04 08:03:14
问题 I know about container managed transactions(CMT). I also know about the different possible values of the enumerated type TransactionAttributeType . Since the client never calls a MDB directly, the attribute types other than the REQUIRED and NOT_SUPPORTED do not make sense for MDB's as there is no client initiated transaction to join to. So when should I annotate the onMessage() method of an MDB with REQUIRED vs NOT_SUPPORTED ? What will be the default behavior in none of the two options is

How to kill db transaction that timed out from jboss

由 二次信任 提交于 2020-01-01 14:29:26
问题 I use jboss 4.2.3. It has setting "TransactionTimeout" (in jboss-service.xml), that specifies how long Transaction is allowed to execute. Unfortunately, when the timeout passes, the execution isn't aborted right now, if the transaction is doing something, only it is marked to be rolled back later. The effect is - when I have long lasting transaction and thread is wainting on preparedStatement.execute for example, and when the TransactionTimeout passes, nothing happend, client still hang, only

事务模型

3种事务模型 本地事务模型 本地事务模型的名称来自于它实际上不是管理事务的框架，而是本地资源管理器。资源管理器是与之通信的数据源的实际提供者。例如，对于数据库，资源管理器是通过数据库驱动程序和DBMS实现的。对于JMS，资源管理器是通过特定的JMS提供程序实现的队列（或主题）连接工厂。使用本地事务模型，开发人员管理连接，而不是事务。实际管理本地事务的是DBMS或JMS提供程序。关于本地事务， 事实是事务管理由底层数据库(DBMS)处理，如果是jms，则由底层消息传递提供程序处理。从开发人员的角度来看，我们不管理本地事务模型中的事务，而是管理连接 。下面的代码示例演示了使用直接JDBC代码的本地事务模型的使用： public void updateTradeOrder(TradeOrderData order) throws Exception { DataSource ds = (DataSource) (new InitialContext()).lookup( "jdbc/MasterDS"); Connection conn = ds.getConnection(); conn.setAutoCommit(false); Statement stmt = conn.createStatement(); String sql = "update trade_order ...

问题 I am upgrading an application from Hibernate 3.6.10.Final to 5.0.7.Final The main issue I have right now is that when before the Oracle dialect would generate a fast enough query like this : SELECT * FROM MY_TABLE WHERE SDO_RELATE(geom,SDO_GEOMETRY(?,4326),'mask=INSIDE+COVEREDBY') ='TRUE' Now it will generate something terribly slow: SELECT * FROM MY_TABLE WHERE MDSYS.OGC_WITHIN(MDSYS.ST_GEOMETRY.FROM_SDO_GEOM(geom),MDSYS.ST_GEOMETRY.FROM_SDO_GEOM(?))=1 This one will not finish on time and
