并行批处理中的死锁问题（Invoice Posting ax 2009）答案

【问题标题】：Deadlocking issue in parallel batch processing (Invoice Posting ax 2009)并行批处理中的死锁问题（Invoice Posting ax 2009）
【发布时间】：2016-05-07 16:28:34
【问题描述】：

我收到错误消息“无法在 SalesParmSubTable 中选择记录。死锁，一个或多个用户同时锁定了整个表或其中的一部分”。

我使用 sql profiler 来获取死锁跟踪。有人可以帮忙改正吗。

【问题讨论】：

这似乎表明提到的 SELECT 是将要发生更新的事务的一部分。您能否确认在同一交易中是否确实存在（潜在）更新？

【解决方案1】：

我认为我们不能仅仅通过知道死锁正在发生来解决死锁问题......我们需要知道为什么或什么过程正在发生。

它看起来像是清理操作或销售订单过帐，因为它正在寻找不存在 SalesParmLine 记录的 SalesParmTable 记录。您可以使用该查询在代码中查找 select 语句并向后工作以查看启动它的进程。

我认为更好的方法是，当它发生时，找出用户当时在做什么。检查批处理作业以查看两个批处理作业是否同时执行相同的操作。
