DynamicCRM清理PrincipalObjectAccess表，清理POA，清理WorkFlowLog(轉)

在CRM2011長時間運行後，發現PrincipalObjectAccess表、AsyncOperationBase表、WorkflowLogBase表產生了上千萬條的數據，導致系統運行緩慢。

經過查找處理辦法，積累了下面的經驗：

微軟官方給出的清理辦法：https://support.microsoft.com/en-gb/kb/968520

IF EXISTS (SELECT name from sys.indexes
                  WHERE name = N'CRM_AsyncOperation_CleanupCompleted')
      DROP Index AsyncOperationBase.CRM_AsyncOperation_CleanupCompleted
GO
CREATE NONCLUSTERED INDEX CRM_AsyncOperation_CleanupCompleted
ON [dbo].[AsyncOperationBase] ([StatusCode],[StateCode],[OperationType])
GO

while(1=1)
begin
 declare @DeleteRowCount int = 10000
 declare @rowsAffected int
 declare @DeletedAsyncRowsTable table (AsyncOperationId uniqueidentifier not null primary key)
 insert into @DeletedAsyncRowsTable(AsyncOperationId)
 Select top (@DeleteRowCount) AsyncOperationId from AsyncOperationBase
 where 
  OperationType in (1, 9, 12, 25, 27, 10) 
  AND StateCode = 3 
  AND StatusCode in (30, 32)
 
 select @rowsAffected = @@rowcount 
 delete poa from PrincipalObjectAccess poa 
   join WorkflowLogBase wlb on
    poa.ObjectId = wlb.WorkflowLogId
   join @DeletedAsyncRowsTable dart on
    wlb.AsyncOperationId = dart.AsyncOperationId
 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 WorkflowWaitSubscriptionBase from WorkflowWaitSubscriptionBase WS, @DeletedAsyncRowsTable d
 where 
  WS.AsyncOperationId = d.AsyncOperationID 
 delete AsyncOperationBase From AsyncOperationBase A, @DeletedAsyncRowsTable d
 where 
  A.AsyncOperationId = d.AsyncOperationId
 /*If not calling from a SQL job, use the WAITFOR DELAY*/
 if(@DeleteRowCount > @rowsAffected)
  return
 else
  WAITFOR DELAY '00:00:02.000'
end
