Hi,
We are inserting huge amount of data in a table. We are keeping the data in table for 1 month. Amount of data inserted is around 15MM records per day and length of record is about 2500 (variable).

My question is, whether dumping this data in a TAPE weekly and keeping only 1 week of data in table will reduce the cost? I want to know TAPE is cheaper or DB2 table?

Thanks.
PS

The answer to that should be obvious to you.

The real question is, if the intention is to hold the data for one month, is it really likely that for the last three weeks that tape is an acceptable medium for data-enquiry. This seems unlikely in general, but obviously it depends entirely on the specifics of the data.

How do you propose to query the data on the tape- it is no longer a DB2 table but a sequential dataset? You would have to write programs to run in batch to handle queries against that data.

Hi Bill/Nic,

We do not query the data regularly unless when there is a issue and need to check the data, and this scenario is very rare in our environment. So we are least bothered on data query.
