DB2将旧数据存档到另一个服务器上的DB2

Question

我需要将数据从db归档到db，这是一个完全不同的服务器（DB2）。我可以通过以下步骤来做到这一点，但性能是问题所在。我有非常大量的数据要存档。无论如何使用优化的归档性能来做到这一点？

/* 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

按CREATED_TIME对源表和归档表进行分区。然后，您将能够简单地从源表中分离分区并将其附加到归档表，这几乎是即时的。
