其他状态数据(如事务率)是根据应用程序域划分的,并只有在统计信息设置被启用时才会累计,如下图7所示。
Other status data such as transaction rates are segmented by application domain and are accumulated only if the statistics setting configuration is enabled, as shown in Figure 7 below.
如果底层驱动程序不支持事务,那么将会抛出一个PDOException(无论错误处理设置是怎样的:这总是一个严重错误状态)。
If the underlying driver does not support transactions, a PDOException will be thrown (regardless of your error handling Settings: this is always a serious error condition).
无状态会话Bean的声明式事务设置可以在ejb部署描述符(ejb - jar . xml)中完成。
The declarative transaction Settings for the stateless session bean are done in the ejb deployment descriptor (ejb-jar.xml).
