服务代理已备份，现在可以接收，但似乎没有处理

20

事件通知有问题。在将消息发送到的机器/驱动器/数据库上（接收者），当没有人看时，驱动器已装满，因此已被整天备份。

现在我们已经释放了驱动器上的空间，它正在接受消息到队列中，但是它似乎没有在处理它们-没有插入新记录，即使队列现在有2200万条消息并且正在增长（！）。队列已启用：

is_activation_enabled = 1
is_receive_enabled = 1
is_enqueue_enabled = 1

我在中看到了激活的SP activation_procedure，但是当我查看时SP_WHOISACTIVE，看不到任何活动的阅读器。

在我再次烧毁驱动器之前-我在做什么错？如何获取它来处理或刷新消息？提前致谢。

更新资料

一个想法-自从有了以来is_enqueue_enabled，也许它可以存储所有消息，直到可以处理所有消息为止？如果是这样，我可以安全地关闭它吗？

--History:  1.00 2012/08/27 first release
--          1.01 2012/09/05 added server-based exclusions and eventsubclass = 0
--          1.1  2012/09/17 added exclusion_sets which allow multi-condition filtering and improved performance
--          1.11 2012/10/05 removing the 1=1 as per suggestion by Rusanu; 
--                              this could cause it to spin forever, blowing out the error_log..and the drive.
--          1.12 2012/11/14 adding a RETURN in the @@ROWCOUNT. It fails to exit and then hits a COMMIT, causing records
--                              in enaudit_error.  That was due to the 1.11 change where I no longer use a 1=1.
--          1.13 2014/01/16 changing ERRORLOG to write the first 500 chars to the CommandText field, as tested in Canada.

因此，根据问题的描述，您正在使用内部激活。sys.dm_broker_activated_tasks中列出了什么吗？您的激活程序是什么样的？您可以在这里发布吗？该过程可能试图立即处理所有消息（即，在一个事务中），这可能很糟糕。同样，没有什么可以阻止您自己手动进行激活。
— Ben Thul 2015年

由于有毒消息（失败太多），可能禁用了队列。请查询sys.transmission_queue并告诉我们它正在报告什么错误。如果我的怀疑是正确的，那么您应该尝试使用ALTER QUEUE语句重新启动队列。

@BenThul将激活的存储过程代码添加到该问题。FWIW，我不使用1 = 1。几年前，我与Remus Rusanu进行了交谈，他谈到了毫无理由使用它的原因，我相应地修改了我的产品。话虽如此，我可能应该考虑将其更改为以速度执行100/1000的批处理。但是在备份之前，它一直像冠军一样工作，所以我讨厌触摸它。
— mbourgon 2015年

我不同意循环对于您现在所处的情况是不必要的。根据BOL的这篇文章（technet.microsoft.com/en-us/library/…），激活不太可能经常触发。这就是为什么在触发该消息时，您希望每个过程都继续处理消息，直到没有剩余要处理的消息为止。只是我的两分钱。为了从现在的漏洞中解脱出来，您可以while exists (select 1 from dbo.ENAudit_SBQueue) begin exec [dbo].[Parse_EN_Messages]; end在SSMS中执行类似的操作来伪造它。

对于tcp端点，双方都应考虑使用的服务acct并连接权限-尝试重新授予权限，然后在端点上重新启动->即使gui或dmv说已启动。
