查询词典 concurrency

The concurrency based on two-phase locking of relations and high priority is presented in transaction management, and was implemented by multiple thread technology.

为适应工控系统网络化、集成化的发展趋势，提出了利用分布式对象技术设计综合自动化系统的思想。

Selecting COM thread model is an important part of server component development since server component will be accessed by multiple concurrency users and thread model has much greater influence on distributed server application.

计算机工程与设计， 2004年 12期选择线程模型是服务器组件开发中重要的一步。

Therefore, control of data concurrency and data consistency is vital in a multiuser database.

因此在多用户数据库中，对数据并发访问及数据一致性进行控制是两项极为重要的工作。

This paper presents the concurrency control scheduling for the object-oriented distributed transaction processing in the workflow management system with massage queue and thread architecture by using lock of page unit.

使用消息队列和多线程，以页为封锁单元，给出一个基于工作流管理系统的面向对象分布事务的并发控制调度算法。

The transaction manager mechanism is responsible for the system concurrency through the two-phase lock and time-span deadlock detection. The lock unit achieves object-level. With the help of the database diary and AI file, it provides strong ability to recover from various database breakdowns.

事务管理机构通过两阶段锁定和超时死锁检测，完成各站点用户对数据库访问的并发控制，其封锁粒度达到对象级；通过日志记录和后备文件AI，实现系统强有力的故障恢复功能。

If a "reasonable" notion of database consistency is to be supported (I.c. the database system is to enforce it automatically), there are bound to be" conflict" situations where one transaction comes into an access conflict against some other transaction. If await is to be avoided,some means of a negotiated settlement of the conflict must be provided, thereby dragging the users into the details of concurrency control.The single-database model is more appropriate-ate than the multiple-database model in an environment where it is difficult to determine in advance logical partitions of the database that correspond to work to be performed, and the users closely cooperate.

如果一个数据库一致的合理观念要得到支持（即数据库系统要自动实行这个观念）、一定会有矛盾的情形产生、在这种情形中一个业务与其它业务产生存取矛盾如果要避免等待，就必须提供某种协商解决矛盾的方法，从而迫使用户详细了解并行控制单一数据库模式在某一种环境中比多个数据库模式更恰当，在这个环境中，要事先确定与要执行的工作相适应的数据库的逻辑分割是很难的，同时用户们又紧密地合作在一起。
