Microsoft Dynamics CRM 4.0 性能优化之一

当您运行 Microsoft Dynamics CRM 4.0 时，则 AsyncOperationBase 表将增大到很大。 如果表包含数百万个记录，性能是速度较慢。

详见：http://support.microsoft.com/kb/968520/

但是，该操作会删除销售预期报表涉及的数据，影响了该报表的正常使用。所以笔者经过测试，做了如下修改，仅供参考。

1) 停止crm服务器的IIS，备份你的 CRM databases

2) 建立两个索引(index)在数据库里 :

CREATE NONCLUSTERED INDEX CRM_AsyncOperation_CleanupCompleted

ON [dbo].[AsyncOperationBase] ([StatusCode],[StateCode],[OperationType])

GO

CREATE NONCLUSTERED INDEX CRM_DuplicateRecord_CleanupCompleted

ON [dbo].[DuplicateRecordBase] ([AsyncOperationID])

GO

3) 停止 CRM 异步服务 Microsoft Dynamics CRM Async Service

4) 打开SQL Server Management Studio , 运行如下代码

declare @DeleteRowCount int

Select @DeleteRowCount = 2000

declare @DeletedAsyncRowsTable table (AsyncOperationId uniqueidentifier not null)

declare @continue int, @rowCount int

select @continue = 1

while (@continue = 1)

begin

begin tran

insert into @DeletedAsyncRowsTable(AsyncOperationId)

Select top (@DeleteRowCount) AsyncOperationId

from AsyncOperationBase

where ( OperationType in (1, 9, 12, 25, 27) AND StateCode = 3 AND StatusCode in (30, 32) )

or ( OperationType in (10) AND StateCode = 3 AND StatusCode in (32) )

Select @rowCount = 0

Select @rowCount = count(*) from @DeletedAsyncRowsTable

select @continue = case when @rowCount <= 0 then 0 else 1 end

if (@continue = 1)

begin

delete WorkflowLogBase from WorkflowLogBase W, @DeletedAsyncRowsTable d

where W.AsyncOperationId = d.AsyncOperationId

delete BulkDeleteFailureBase From BulkDeleteFailureBase B, @DeletedAsyncRowsTable d

where B.AsyncOperationId = d.AsyncOperationId

delete AsyncOperationBase From AsyncOperationBase A, @DeletedAsyncRowsTable d

where A.AsyncOperationId = d.AsyncOperationId

delete @DeletedAsyncRowsTable

end

commit

end
