Ssis 如何清理SSIDB?
当我设置这个时,我忽略了保留期。我的数据库变得相当大,所以我想减小它的大小。如果我只是更改保留期,它是365,则会导致运行我的包的SSI出现问题。我甚至以较小的增量对其进行了更改,但删除语句将创建锁,从而阻止新作业运行Ssis 如何清理SSIDB?,ssis,sql-server-2012,Ssis,Sql Server 2012,当我设置这个时,我忽略了保留期。我的数据库变得相当大,所以我想减小它的大小。如果我只是更改保留期,它是365,则会导致运行我的包的SSI出现问题。我甚至以较小的增量对其进行了更改,但删除语句将创建锁,从而阻止新作业运行 有没有办法解决这个问题?我曾考虑过创建一个新的SSIDB。菲尔·布拉默(Phil Brammer)遇到了这个问题,以及与SSIS目录的维护和提供相关的许多其他问题,他在自己的文章中介绍了这些问题 根本问题 根本问题是MS试图在设计SSI时考虑到RI,但它们很懒惰,允许级联删除而不
有没有办法解决这个问题?我曾考虑过创建一个新的SSIDB。菲尔·布拉默(Phil Brammer)遇到了这个问题,以及与SSIS目录的维护和提供相关的许多其他问题,他在自己的文章中介绍了这些问题 根本问题 根本问题是MS试图在设计SSI时考虑到RI,但它们很懒惰,允许级联删除而不是显式处理它们 新的SSIS 2012目录数据库SSIDB采用了一些基本的索引,并将引用完整性设置为在大多数表之间进行级联删除 输入SQL代理作业“SSIS服务器维护作业”。默认情况下,此作业设置为每天午夜运行,并使用两个目录参数发挥作用:“定期清理日志”和“保留期天数”。设置这两个参数后,维护作业将清除所注保留期以外的所有数据 此维护作业从internal.operations中一次删除10条记录,然后级联到下游的许多表中。在我们的案例中,我们每天要删除大约3000条操作记录,每次删除10条!这将从internal.operation_消息转换为160万行。那只是一张下游的桌子!整个过程完全地、彻底地将SSISDB数据库从任何SELECT/INSERT数据中锁定 决议 在MS改变工作方式之前,支持的选项是 将维护作业计划移动到更适合您的环境的时间 我知道,在我当前的客户机上,我们只在凌晨加载数据,因此SSIDB在工作时间内保持安静 如果在一段安静的时间内运行维护作业不是一个选项,那么您需要设计自己的delete语句,以尽量减少级联删除 在我目前的客户那里,在过去的10个月里,我们每晚运行大约200个软件包,而且已经有365天的历史了。从数量级上看,我们最大的表是
Schema Table RowCount
internal event_message_context 1,869,028
internal operation_messages 1,500,811
internal event_messages 1,500,803
所有这些数据的驱动程序internal.operations中只有3300行,这与Phil关于这些数据以指数方式增长的评论一致
因此,确定要清除的操作id,并将从叶表中删除的内容返回到核心internal.operations表
通常的警告适用
不要相信来自互联网上随机的代码
使用ssistalk和/或系统表中的图表来识别所有依赖项
您可能只需要将删除操作分段为较小的操作
删除操作的RI可能会使您受益,但一定要使用check选项重新启用它们,这样它们才是可信的。
如果操作持续时间超过4小时,请咨询dba

评论中提到
SSIS DB可能会有不同的表名,但最后会有扩展。它可以是internal.event\u message\u context,而不是internal.event\u context\u scaleout。它可以是internal.operations\u messages\u scaleout,而不是internal.operations\u messages。只需相应地修改代码中的表名,它就会正常运行 如果您在Azure Data Factory中使用SSIS IR,则肯定会出现这种情况。您会发现普通表仍然存在,但为空,*\u scaleout版本包含所有数据 工具书类
我创建了一个类似的存储过程来进行下面的归档。如果有任何错误,请告诉我。我不提供任何保证,但对我来说效果很好。这段代码绝对不是经过润色的,但我想与大家分享一下,即使用临时表意味着一次只能运行一次,也许一个会话范围的表会更好 我遇到了一个问题,MS自己的clean过程会将LDF文件吹出并长时间锁定表,一旦导致服务器空间不足。我决定写我自己的,先删除较大的表,然后删除操作表。下面的过程在日志空间中使用的空间永远不会超过1GB,并且不会在很长时间内锁定表,这是SSIS作业必须全天运行时遇到的难题 首先,它记录到一个表中
CREATE TABLE [dbo].[ETL_SSIS_Operations_Archived](
[id] [int] IDENTITY(1,1) NOT NULL,
[operation_id_str] [varchar](900) NOT NULL,
[event_messages_context] [int] NULL,
[event_messages] [int] NULL,
[operation_messages] [int] NULL,
[num_operators] [int] NULL,
[chunksize] [int] NULL,

[executionSecs] [int] NULL,
[DelOperationsDateStarted] [datetime] NULL,
[DelOperationsDateFinished] [datetime] NULL,
[DelOperationsExecutionSecs] [int] NULL
) ON [PRIMARY]
GO
并使用临时表
CREATE TABLE [dbo].[tmp_etl_operations_id](
[operation_id] [int] NULL,
[dateCreated] [datetime] NULL default getdate()
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[tmp_etl_operations_id] ADD DEFAULT (getdate()) FOR [dateCreated]

已从本文中找到有用的清理脚本:
还考虑将数据库切换到简单恢复模式,但为日志文件留出足够的空间。
< P>运行这个SPROC:EXEC [internal].[cleanup_server_retention_window]
这是非常有帮助的。我能把数据库吹走,从头开始吗?我失去了历史,但还有其他的失败吗?只要你有你的.ispac
handy+环境内容handy或不介意重新创建,drop and recreate将可能更新工作,包括@MartinSmith Done和thank you。顺便说一句,由于我必须清理一个2012年的SSISDB,它将床上的东西清理干净,所以SSISDB很可能有不同的表名,并且在现在结束时会有扩展。它可以是internal.event\u message\u context,而不是internal.event\u context\u scaleout。它可以是internal.operations\u messages\u scaleout,而不是internal.operations\u messages。只需相应地修改代码中的表名,它就会正常运行。
