The retry is used in case a concurrency exception does occur in the query table execution and the query table engine needs to retry the claim operation. 重试仅用于查询表执行时出现并发异常且查询表需要重新申明的情况下。
There's a potential concurrency nightmare in acquiring a lock, doing the operation, and releasing the lock each time. 每次在获取锁、执行操作和释放锁的过程中,都存在潜在的并发困境。
With optimistic concurrency control, the database manager releases the row or page locks immediately after a read operation. 通过实现乐观并发控制,数据库管理器可以在完成读操作后立即释放行或页锁。
The concurrency operation of the desktop databank could be conducted. 对桌面数据库并发操作的处理;
A transaction supporting workflow can apply transactions that originally proposed in the context of databases to the context of workflow to deal with error recovery and concurrency control, thus guaranteeing the consistency and correctness of the operation results. 支持事务处理的工作流是将数据库管理系统中的事务概念应用在工作流管理系统中,来处理错误恢复和并发控制,以保证运行结果的一致性和执行正确性。
