DB2在其他服務器上對舊數據進行DB2歸檔

Question

我需要將數據從數據庫歸檔到位於完全不同服務器（DB2）的數據庫中。我可以通過以下步驟來做到這一點，但表現是問題所在。我有非常大量的數據要歸檔。無論如何要做到這一點與優化存檔性能？

/* TEST WITH 1 TABLE */ 

--1. RETRIEVE IDs AND SAVE IN LIST - [USE LOOP TO PUSH RECORDS BASED ON IDs IN AN ARRAY] 
SELECT ID FROM TABLE_1 
WHERE CREATED_TIME >= '2013-08-07 10:06:22' AND CREATED_TIME <= '2013-08-07 11:09:43' 
ORDER BY A.ID ASC 




--2. DROP INDEXES [TOO SLOW!!!] 
ALTER TABLE TABLE_1_ARC DROP PRIMARY KEY 




--3. INSERT RECORDS INTO ARC TABLE [STORED PROCEDURE TO INSERT IN ALL TABLES???] 
INSERT INTO TABLE_1_ARC 
SELECT * FROM TABLE_1 
WHERE CREATED_TIME >= '2013-08-07 10:06:22' AND CREATED_TIME <= '2013-08-07 11:09:43' 
ORDER BY ID ASC 
--LOOPING THROUGH ARRAY FROM STEP 1 WILL BE USED HERE INSTEAD OF WHERE 


--4. DELETE ARCHIVED RECORDS FROM OPERATIONAL TABLE [STORED PROCEDURE TO DELETE EVERY FEW RECORDS???] 
DELETE FROM TABLE_1 
WHERE CREATED_TIME >= '2013-08-07 10:06:22' AND CREATED_TIME <= '2013-08-07 11:09:43' 
--LOOPING THROUGH ARRAY FROM STEP 1 WILL BE USED HERE INSTEAD OF WHERE 



--5. PUT INDEXES BACK [TOO SLOW!!!] 
ALTER TABLE TABLE_1_ARC ADD PRIMARY KEY (ID) 

Answer 1

通過CREATED_TIME對源表和歸檔表分區。然後，您將能夠簡單地從源表中分離分區並將其附加到歸檔表中，這幾乎是瞬間的。
