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).
在无状态会话bean上下文外部的客户机层中使用编程事务时，您不需要设置事务类型。
When you use programmatic transactions in the client layer outside of the context of a stateless session bean, you don't need to set the transaction type.
但是，在执行拦截之后，应用程序事务马上把修改提交给它的数据库 —— 把新主数据记录的状态设置为 created。
Nonetheless, right after the interception occurred, the application transaction commits the change to its database -- marking the new master data record with the status created.
在设置为after_commit参数，发起事务的客户端仅在服务器向存储引擎写入数据并接受从库得到确认之后才返回状态。
With AFTER_COMMIT, the client issuing the transaction gets a return status only after the server commits to the storage engine and receives slave acknowledgment.
