Ravindra,
That is basically what I do each 6 months for 6 large tables. I created a function
that will insert the rows into an existing table and commit after so many rows. Then I
use a script to delete the rows from the original table by date range and commit after
each range specified.
It works great as I have about 1.6 GIG in the largest table and that one takes the
better part of the day. The limiting factor is the size of the archivelog storage
space 4 GIG so I have to watch it constantly and more the logs of to a different
location.
Listed below is an example of my function to insert rows...
============
declare
i number :=0;
cursor c1 is
select RETNBR ,
SALEDATE ,
GAMECODE ,
ORDERAMT ,
CONFIRMATIONAMT,
ACTIVATIONAMT ,
SETTLEMENTAMT ,
RETURNAMT ,
CASHAMT ,
SALESCOMMAMT ,
CASHBONUSAMT ,
TOTCOMMAMT
from glcIDsr_curr
WHERE SALEDATE between '06-01-2001' and '06-30-2001';
IDSR_UPDATE C1%ROWTYPE;
begin
open c1 ;
loop
fetch c1 into IDSR_UPDATE ;
exit when c1%NOTFOUND ;
insert into GLCIDSR_HIST01
values(IDSR_UPDATE.RETNBR,
IDSR_UPDATE.SALEDATE,
IDSR_UPDATE.GAMECODE,
IDSR_UPDATE.ORDERAMT,
IDSR_UPDATE.CONFIRMATIONAMT,
IDSR_UPDATE.ACTIVATIONAMT,
IDSR_UPDATE.SETTLEMENTAMT,
IDSR_UPDATE.RETURNAMT,
IDSR_UPDATE.CASHAMT,
IDSR_UPDATE.SALESCOMMAMT,
IDSR_UPDATE.CASHBONUSAMT,
IDSR_UPDATE.TOTCOMMAMT);
i := i + 1;
if i > 200000
then
commit;
i := 0;
end if;
end loop;
commit;
close c1;
end;
===========
After the deletions are complete I export the remaining data and truncate the table
and then import the data to clean up the tablespace.

I have few tables that will be getting populated with transaction data
continuously.This table
grows to large size.For us once the transaction is completed we don't need
the data to be in the database,
but we cannot delete them either.We need to archive those records and clear
those archived records
from the table.Like out of the 3million records I want to keep this months
records and archive the
remaining.There are few set of tables which needs to be archived and they
are all related.
I can think of creating a new table and populating the table with records
that needs to be archived and
after this those records can be deleted.Ex
create table T1 as select * from <tablename> where id < xxxx;
What is the best way of doing this.
Thanks
Ravindra
