| 1. | Interface , it should be serializable , and it should extend 接口,应该是可串行化的,而且应该扩展 |
| 2. | Indicates serializable update scan 指示可串行更新扫描。 |
| 3. | Indicates serializable range scan 指示可串行范围扫描。 |
| 4. | Key lock within an index that protects a range of keys in serializable transactions Key =索引内保护可串行事务中一系列键的锁。 |
| 5. | This new capability enables you to have a serializable disconnected object 这一新功能使您可以拥有一个可串行化的断开连接的对象。 |
| 6. | Serializable proc exec replicates the execution of the stored procedure only if it is executed within the context of a serializable transaction 仅当存储过程在可串行事务上下文内执行时才复制存储过程的执行。 |
| 7. | Dynamic adjustment of execution order can not only adjust the serialization order dynamically but also adjust the execution order of read and write operations dynamically to avoid the unnecessary restarts efficiently 动态调整执行顺序方法能够动态地调整串行化顺序和读写顺序来寻找可串行化的调度,有效地避免不必要的重启。 |
| 8. | This is referred to as serializability because it results in the ability to reload the starting data and replay a series of transactions to end up with the data in the same state it was in after the original transactions were performed 这称为可串行性,因为它能够重新装载起始数据,并且重播一系列事务,以使数据结束时的状态与原始事务执行的状态相同。 |
| 9. | But at present , there seem to be much deficiencies on the correctness and reliability of workflow and it can not meet the practical needs very well . in this paper , we introduce some transactional properties to workflow and put forward a nested workflow model with transactional characteristics . this model includes nested tasks and dependencies between the tasks , and it is provided with some atm properties such as relaxed isolation and atomicity . further more , we discuss the execution mechanism , system recovery and error handling of workflow on the base of the transactional characteristics . by defining consistency unit and execution atomic unit , we loosen the failure atomicity , serializability of concurrent worflow and isolation between tasks , thus , workflow meets the needs of the application semantics more flexiblly with high correctness and reliability 这个模型包含嵌套任务和任务间的依赖,并具有高级事务模型的一些属性,比如松散的隔离性和原子性。我们又进一步在这个模型的基础上利用这些事务性质提出了有关工作流的执行机制、系统恢复和错误处理等问题的解决方法。通过定义一致性单元和执行单元放松了事务的失败原子性、并发工作流的可串行化要求以及任务间的隔离性,使工作流在具有高可靠性和正确性的前提下更灵活地满足实际应用语义的要求。 |
| 10. | Deferred global view maintenance can speed up the update transactions by shifting maintenance into a deferred transaction , but even strict two phase locking ( 2pl ) can not guarantee the serializable execution of transactions in this case . this paper develops a serializabitity theory base upon conflicts and serialization graphs in presence of deferred global view maintenance 由于延迟视图维护机制允许修改事务在全局视图没有进行相应的改动之前提交,有暂时的数据不一致情况出现,在这种情况下,即使严格的zpl协议也不能保证全局事务的可串行化执行。 |
