This process effectively delegates transaction coordination to the one-phase commit resource.
此过程有效地指派了对单阶段提交资源的事务协作。
Unlike a two-phase commit process, there is no recovery from a communication failure with a one-phase commit resource.
与两阶段提交进程不同,单阶段提交资源在通信失败时无法恢复。
Unlike a two-phase commit resource, there is no recovery from a communication failure with a one-phase commit resource.
不像两阶段提交资源,单阶段提交资源不能从通信故障中恢复。
The two-phase commit resources are then committed or rolled back depending on the response from the one-phase commit resource.
然后,两阶段提交资源或者提交或者回滚,具体取决于来自单阶段提交资源的响应。
Such a communication failure during commit of the one-phase commit resource introduces the risk of a mixed outcome to the transaction.
在单阶段提交资源提交过程中,这样的通信故障引入了混合事务结果的危险。
This is because the EJB container cannot commit a one-phase commit resource together with two-phase commit resources in a global transaction.
这是因为在全局事务中ej b容器不能同时提交单阶段提交资源和两阶段提交资源。
The two-phase commit resources are rolled back, but the outcome of the one-phase commit resource is unknown; it could have committed or rolled back.
两阶段提交资源可以回滚,但单阶段提交资源的结果是未知的,它可能已提交或者已回滚。
Thus, a communication failure during commit of the one-phase commit resource introduces the risk of a mixed outcome to the transaction (the heuristic hazard).
因此,在提交单阶段提交资源时通信失败会带来混合的事务结果风险(启发式危险)。
Resource managers are the only ones who know their resources and how to commit them or roll them back.
只有资源管理器知道它们的资源及提交或回滚它们的方法。
If another resource becomes involved in the transaction, you have forced an unnecessary two-phase commit, causing an additional prepare flow.
如果在事务中涉及另一项资源,就会强制进行不必要的两阶段提交,导致额外的准备流程。
The transaction manager asks all the resource managers to prepare to commit recoverable resources (prepare).
事务管理器请求所有资源管理器准备提交可恢复资源(准备)。
Upon receipt of the commit flow, the resource manager finalizes the updates to recoverable resources, and releases any locks held on the resources.
资源管理器一收到提交流程就结束对可恢复资源的更新,并且释放所有抓住资源不放的锁。
If one resource commits successfully but the system crashes before the other resource can commit successfully, the application again is inconsistent.
如果一个资源成功提交,但在另一个资源成功提交前系统崩溃,那么也会造成应用程序状态不一致。
A two-phase commit allows several cooperating entities, known as resource managers, to participate in a single distributed unit of work coordinated by a transaction coordinator.
两阶段提交允许多个协作实体(称为资源管理器)参与到由事务协调器进行协调的单个分布式工作单元中。
The CICS resource adapter supports local transactions, which means that the CICS server manages the transactions with one-phase commit or rollback.
CICS资源适配器支持本地事务,这就意味着CICS服务器通过一阶段提交或回滚管理事务。
Because two team members can commit changes to the same resource, conflicts can occur and must be dealt with.
因为两个团队成员可以提交对同一资源的更改,所以有可能发生冲突,必须解决这种冲突。
The resource manager does not perform any logging and does not participate in the second phase of the two-phase commit.
资源管理器不执行任何记录。并且不参与两阶段提交中的第二个阶段。
The SCA container USES a two phase commit to achieve atomicity when multiple transactional resource managers are used.
当使用多个事务资源管理器时,sca容器使用一个两阶段提交实现原子性。
If it detects that all the resources involved in the transaction are the same, it can skip the two-phase commit and let the resource manager handle the transaction by itself.
如果它检测出所有与事务相关的资源都一样,它可以跳过两阶段提交并让资源管理器自己来处理事务。
This means that, at a minimum, the resource adapter must make start, commit or rollback, and end flows to the back end.
这意味着,资源适配器至少必须进行开始、提交或者回滚,并结束流程返回后端。
XA transaction — a resource adapter that can participate fully in a two-phase commit process, and which can influence the outcome of the global transaction.
xa事务——可以完全参与两阶段提交进程的资源适配器,该资源适配器可以影响全局事务的结果。
In the Stage 2, providing all the resource managers voted positively, the transaction manager replies to each resource manager with a commit flow.
在阶段2中,假设所有的资源管理器都做了确定的答复,事务管理器回复每个资源管理器一个提交流程。
Some configurations, such as those with only one database resource, do not require the full data integrity that is provided by the two-phase commit protocol of the XA interface.
有些配置(如只有一个数据库资源的那些配置)不需要xa接口的两阶提交协议提供的数据完整性。
CICS ECI XA resource adapter — This resource adapter implements XA transaction support, and has full support for global two-phase commit transactions.
CICSECIXA资源适配器——此资源适配器实现XA事务支持,而且完全支持全局两阶段提交事务。
However, when CICS TG is running on a distributed platform, a one-phase commit connection still has to be used, and so CICS TG has to be considered a local transaction capable resource manager.
不过,当CICSTG在分布式平台上运行时,仍必须使用单阶段提交连接,因此CICS TG需要考虑使用支持本地事务的资源管理器。
Some transaction managers configured for XA communication restrict application programmers from using resource manager-specific two-phase commit statements.
为xa通信配置的某些事务管理器会限制应用程序编程人员使用特定于资源管理器的两阶段提交语句。
The resource acknowledges the Commit and returns a Committed message to the Coordinator (CoordinatorRef).
资源接受Commit,然后把Committed消息返回给协调器(CoordinatorRef)。
The application or the individual resource manager is responsible to commit or rollback interactions. For example.
应用程序或各个资源管理器负责提交或回滚交互。
In phase 2 (commit phase), WebSphere transaction manager skips the communication with this resource manager, and it will not disk force or log any activities related to this resource manager.
在阶段2(提交阶段)中,WebSphere事务管理程序略过与资源管理程序的通信,并且它并不冒险强制或记录任何与这个资源管理程序相关的活动。
This allows a single one-phase commit capable resource (such as a CICS ECI Connection) to participate in a global transaction with any number of two-phase commit capable resource managers.
这允许单一的具有单阶段提交能力的资源(例如CICSECIConnection)参与拥有许多具有两阶段提交能力的资源管理器的全局事务。
