For methods starting with insert or update, you may want full transaction propagation; but for other methods, you may want lightweight read-only propagation. 对于以insert或update单词开始的方法,您可能想要完整的事务传播,而对其他方法,您想要轻量级的只读传播。
For the example, it is not the SELECT statement that caused the problematic lock, but the UPDATE statement executed just before the SELECT statement in the same transaction. 例如,不是SELECT语句造成产生问题的锁,但UPDATE语句恰好在同一事务中在SELECT语句前执行。
Using this WebLogic extension makes it impossible for another transaction to read or update data while the first transaction is running. 使用此WebLogic扩展会使当第一个事务正在运行时,另一个事务读取或更新数据成为可能。
It doesn't do the actual update until the implicit transaction is committed, however, using the commit() method on the ObjectContainer. 但是,在使用ObjectContainer上的commit()方法提交显式事务之前,它不会进行实际更新。
Environments with high update transaction rates might require more page cleaners to be configured. 具有较高事务更新率的环境可能需要配置更多页面清洗器。
This support allows you to write a generic update procedure that can be used for any update transaction, regardless of the columns being updated. 这个支持允许您编写一个可用于任何更新事务的通用更新过程,而不管正在更新哪些列。
Order documents do not get updated in our scenario ( hence no update order transaction) 在我们的场景中不更新订单文档(因此没有订单更新事务)
It will also invoke the callback function response to confirm the update when the transaction completes. 它还将在事务完成时调用回调函数response来确认更新。
The delay-updates-until-end-of-tx element is set to True by default to update the persistent store of all beans in a transaction when the transaction completes. delay-updates-until-end-of-tx元素缺省为True,在这种情况下,当事务完成时会更新事务中所有bean的持久存储。
If the update failed and the transaction rolled back, another message could be sent to the JMS provider on a separate destination, describing the reason for the failed transaction. 如果更新操作失败并且事务回滚(rollback),则再发送一条消息到一个单独的目的地上的JMS提供者那里,同时给出对事务失败的原因的描述。
Unneeded indexes impair the performance of insert/ update/ delete actions, and consume storage and transaction log space. 不必要的索引会对插入/更新/删除动作的性能造成不良影响,并消耗存储和事务日志空间。
For this reason, applications with few database update operations in a single LUW are good candidates for this transaction strategy. 因此,在单个LUW中几乎没有数据库更新操作的应用程序适合使用这种事务策略。
However, if one public update method invokes another, the transaction owner may not have control of the rollback logic in some circumstances. 然而,如果其中一个公共更新方法调用了另一个,那么事务所有者在某些情况下可能无法控制回滚逻辑。
Such updates increase the processing load associated with each affected search folder, and each such update is logged in the transaction logs. 此类更新增加了与每个受影响的搜索文件夹关联的处理负载,并且每个此类更新都记录在事务日志中。
During an insert or update transaction, new rows are added to both the inserted table and the trigger table. 在执行插入或更新事务过程中,新行会同时添加到inserted表和触发器表中。
If you are updating two or more related tables, then you should include all the update logic within a transaction. 如果要更新两个或更多相关表,则应将所有更新逻辑包括在一个事务内。
For clarity this walkthrough does not use a transaction, but if you are updating two or more related tables, then you should include all the update logic within a transaction. 为了清楚起见,本演练未使用事务,但是如果您要更新两个或多个相关表,则应在一个事务中包含所有更新逻辑。
Working with QA and sourcing for npi& nii process, including new item setup, new formula update and new material implementation to ensure the transaction smoothly and limit the quantity of dead inventory. 与质检及采购部门一起,建立或更新包括产品的名称,产品生产公式及原料的采用方案等档案,并要确保这一过程的顺畅而且要减少库存积压的数量。
On-Line update How many ILF's are updated by On-Line transaction? 在线更新多少ILF被在线事务所更新?
Unless you cannot avoid processing the incoming messages and database update in a single unit of work, consider using local transaction for performance reasons. 除非您不能避免在单个工作单元中处理收到的消息和数据库升级,否则因为性能的原因要考虑用局部事务处理。
In the multiversion schema, a transaction can get the correct version of a data item without holding and locks or latchs and the read-only transactions can proceed without being blocked by any update transaction. 在多版本存储技术的实现方案中,可能存在同一个数据项的多个版本,事务可以读取正确的数据项版本,只读书事务的执行不会被阻塞,只读事务和更新事务之间互不干涉。
This paper also discusses synchronized update of data, in which conflict resolution and synchronized update under distributed environment are studied, and an incremental synchronized update policy based on transaction described with XML is proposed. 本文还讨论了数据同步更新技术,其中重点研究了冲突消解技术和分布式环境下的数据同步更新,提出了基于XML描述事务的增量式数据同步更新策略。
The protocol differentiates between read-only transactions and update transaction. 协议区分只读事务和更新事务。
In the optimization of update transaction, we added a function to the read operation of active transaction to check whether there existed an uncommited data version. 在对更新事务的优化中,将更新事务细分为普通事务和主动事务。对主动事务的读操作加入了检测是否存在未提交数据版本的函数。
This improved algorithm can be applied not only to update of association rules which is caused by increase of transaction in transaction database, but also to the update of association rules which is caused by the change of the supporting degree with the same transaction database. 该算法适用于事务数据库事务增加或支持度阈值变化而引起的关联规则的更新。
We adopt a belief update model, and collect actual transaction data to verify the model. 此研究采用了一个信念更新模型,而且使用实际交易数据验证了此模型。
According to the characteristics of tasks, reputation need not update each time after one transaction or it can update after a fixed number of transactions. 在此方法中可以根据任务的性质在每次交易完成后不必立即对信誉进行更新或者在固定数量的交易后对信誉进行一次更新。
This novel reputation management system is able to evaluate and update the reputations of users according to the transaction history. 这种新颖的信誉系统可以根据交易历史有效地评估、更新用户的信誉。
