proc 실행 중 오류가 발생했습니다. SSIS를 통해 .. 오류 : 테이블

UPDATE ta   
     SET ta.id = 
     CASE 
      WHEN ta.id=tmp.MergeoldId THEN tmp.MergenewId 
      ELSE ta.id 
     END, 
     ta.Id2= 
     CASE 
     WHEN ta.Id2=tmp.MergeoldId THEN tmp.MergenewId

[Execute SQL Task] Error: Executing the query "Exec clk.id_Process ? ,? ,?" failed with the following error: "The instance of the SQL Server Database Engine cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users. Ask the database administrator to check the lock and memory configuration for this instance, or to check for long-running transactions.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Answer 1

이 문제는 The lock manager will not use more than 60 percent of the memory available to SQL Server부터 메모리 부족으로 인한 것입니다. 각각은 (96 바이트) 보유 잠금

SQL Server cannot obtain a lock resource. This can be caused by either of the following reasons:
SQL Server cannot allocate more memory from the operating system, either because other processes are using it, or because the server is operating with the max server memory option configured.
The lock manager will not use more than 60 percent of the memory available to SQL Server.

일반적 SQL 서버는 모든 쿼리 (심지어 선택) 및 적은 양의 메모리를위한 잠금 사용 이용한다. 위의 지식을 바탕으로

--this gives you currently running queries holding more locks 
select * from sys.dm_exec_requests ec 
cross apply 
(SELECT request_session_id, COUNT (*) num_locks 
FROM sys.dm_tran_locks trn 
where ec.session_id=trn.request_session_id 
GROUP BY request_session_id 
)b 

--this gives you locks for allsessions 
SELECT request_session_id, COUNT (*) num_locks 
FROM sys.dm_tran_locks trn 
where ec.session_id=trn.request_session_id 
GROUP BY request_session_id
