Question

我们的应用程序中的jdbc入站通道适配器和消息存储一致地停止查询数据，并且我已经能够将其跟踪到阻塞的Oracle会话。在Oracle中，我们得到了enq：TX - 行锁争用。 DBA将其跟踪到以下内容：

SELECT COMPLETE, LAST_RELEASED_SEQUENCE, CREATED_DATE, UPDATED_DATE
from INT_MESSAGE_GROUP
where GROUP_KEY = :1 and REGION=:2

非常感谢任何有关如何解决此问题的建议。

Answer 1

我认为主要问题是fixed-rate documentMessageStoreReaper，DELETE from INT_MESSAGE_GROUP启动fixed-dealy。您应该将其更改为DELETE from INT_MESSAGE_GROUP以避免并发任务。

由于您说{{1}}非常长，因此任务之间10秒可能还不够。
