In optimistic concurrency control, users do not lock data when they read it. 在乐观并发控制中,用户读取数据时不锁定数据。
The Results pane uses optimistic concurrency control so the grid shows a copy of the data in the database rather than an entirely live view. 结果窗格使用开放式并发控制,因此网格显示的是数据库中的数据副本而不是完全实时的视图。
The transaction failed to commit due to the failure of optimistic concurrency control in at least one of the resource managers. 该事务没有确认,因为至少一个资源管理器里的乐观并发控制失败。
With the optimistic concurrency control, it is easier than ever to allow multiple users to access a database at once and then resolve conflicts quickly and easily. 通过开放式并发控制,允许多个用户同时访问数据库以及随后快速方便地解决冲突都比以往更加容易。
In the protocol, multiversion optimistic concurrency control method was adopted.Technique of multiversion dynamic adjustment of serialization order was used. 协议采用多版木乐观方法，使用多版本动态调整串行次序技术。
Third, a new optimistic concurrency control algorithm based on dynamic adjustment of execution order using commit space in RTDBSs, called OCC-CS, is introduced and the complexity of this algorithm is analyzed. 提出了基于提交范围(CommitSpace)的OCC-CS算法来实现动态调整执行顺序方法，并对OCC-CS算法进行了复杂度分析。

optimistic concurrent control 优化并行控制
optimistic concurrency control 积极的并发控制策略
Allows you to control how SQL statements or stored procedures are created for a data adapter by specifying options for updates, optimistic concurrency, and refreshing the dataset. 通过为更新、开放式并发和刷新数据集指定选项,允许您控制为数据适配器创建SQL语句或存储过程的方式。
This paper introduces the concurrent control policy based on these two characteristics. 本文介绍基于这两个特征的并发控制策略。
And borrow the method that DBMS solve concurrent control, we give a new solutions to the concurrent control of workflow management. 借用数据库解决并发控制的方法，为工作流的并发控制提供了一种新的解决方案。
In addition, its techniques in the CSCD system are also discussed since the strategies of concurrent control are very critical in CSCW systems. 首先，本文分析了当前CSCD中采用的体系结构、异构信息处理、一致性维护和一致性避免等相关技术，并仔细研究了对这些相关技术的典型的控制策略。
There is no specific concurrency control mechanism available. 没有可以使用的特定的并发控制机制。
By contrast, users who use optimistic concurrency do not lock a row when reading it. 对比之下,使用开放式并发的用户在读取行时不会锁定该行。
This paper introduced the two key problems solved by the system: transactional operation and concurrent control,and proposed the lock tie mechanism based on PRI. 详细介绍了系统实现中解决的两个关键问题:事务型操作的处理和并发控制,并提出了基于优先级的锁绑定机制。
Optimistic concurrency improves performance because no locking of records is required, and locking of records requires additional server resources. 由于不需要锁定任何记录,开放式并发将会提高性能,因为锁定记录需要更多的服务器资源。
Because this is not the case in an optimistic concurrency model, connections to the server are free to serve a larger number of clients in less time. 由于在开放式并发模型中并不会这样,所以与服务器的连接可以在较少的时间内为更多的客户端提供服务。
This capability is often used to include original values in the WHERE clause of an UPDATE statement to check for optimistic concurrency violations. 该功能通常用于在UPDATE语句的WHERE子句中包含初始值,以检查开放式并发冲突。
