- This paper introduces some problems which exist in the distributed data function of INFORMIX - Online dynamic server and the principle of two - phase commit protocol. 本文介绍INFORMIX-Online动态服务器的分布式数据处理所涉及到的若干问题并简单叙述两阶段提交协议的原理。
- The Single Phase Commit protocol is more efficient at runtime as all updates are done without any explicit coordination. 单阶段提交协议在运行时更有效,因为所有更新都不经过任何显式协调即完成。
- Abstract: The two phase commit protocol is the simplest and most popular atomic commitment protocol (ACP).It makes the transaction commitment in the distributed systems have atomicity and durability. 摘 要: 两阶段提交协议是最简单且最常用的原子提交协议,该协议使分布式事务的提交具有原子性和持久性。
- two - phase commit protocol 两阶段提交协议
- Method is called, or the two phase commit methods defined in ther. 接口中定义的两阶段提交方法。
- The transaction manager can still send two phase commit notifications instead. 事务管理器仍然可以发送两阶段提交通知。
- To ensure that a single phase commit is performed. 以确保执行单阶段提交。
- Two phase commit protocols(2PC) 两阶段提交协议
- Enlists a volatile resource manager that supports two phase commit to participate in a transaction. 登记支持两阶段提交的可变资源管理器以参与事务。
- Interface, the resource manager must also implement all the methods of the latter for two phase commit notifications. 接口派生,因此资源管理器还必须实现后者用于两阶段提交通知的所有方法。
- Describes an interface that a resource manager should implement to provide two phase commit notification callbacks for the transaction manager upon enlisting for participation. 描述资源管理器为了在登记参与时为事务管理器提供两阶段提交通知回调而应该实现的接口。
- In summary, the two-phase commit protocol and the resource managers combine to make transactions atomic and durable. 总的来说,两阶段提交协议和资源管理器相结合,使事务成为原子的和持久的。
- If immediate updating is used, the changes are propagated immediately using the two-phase commit protocol. 如果使用立即更新,将使用两阶段提交协议立即传播更改。
- Typically, the entire prepare and commit protocol completes in a fraction of a second. 通常,整个准备和提交协议几分之一秒即可完成。
- Interfaces deal with managing distributed transactions across various back ends that support a two-phase commit protocol. 接口负责管理跨支持两阶段提交协议的各种后端的分布式事务。
- Using the WebSphere global transaction, where two-phase commit protocol is in place, will significantly decrease the overall performance. 利用WebSphere全局处理事务,在这里的适当位置提交协议的两种状态,将明显降低总体性能。
- Describes a resource object that supports single phase commit optimization to participate in a transaction. 描述支持单阶段提交优化以参与事务的资源对象。
- Then introduce the infrastructure of MMDB system based on two-phase commit protocol, which is as the support structure of a real-time data processing application. 然后,提出了一种基于两阶段提交协议的内存数据库系统的设计方案,在实时应用中为实时数据处理提供底层支持。
- Enlists a durable resource manager that supports single phase commit optimization to participate in a transaction. 登记支持单阶段提交优化的持久资源管理器以参与事务。
- Enlists a volatile resource manager that supports single phase commit optimization to participate in a transaction. 登记支持单阶段提交优化的可变资源管理器以参与事务。
