How to find out the size of the datafile for a database consist of three tables with following specs:
1 year growth 5 Year growth
Table 1 400,000 record/year, 1 million record/5 year
Table 2 100, 000 record/year, 250, 000 records/5 year
Table 3 45/year, 60/5 year
Table1: Average Record length: 80
Table 2: Average Record length 100
Table3: Average Record length 35
I really need to understand this concept. Also I would like to understand the magic about min. extent, maxextents....
It is difficult to measure the exact size of the datafile for the period of time.
We can calculate approx. datafile size by taking average record length multiply by average no.of records plus add 30% additional size for the particular table. Like wise we can proceed for other tables in the tablespace for the datafile.
I'll send the excell sheet and an explanation on how to use it by tomorrow, as I waited for a max. number of people to answer, but I am now in a hurry, (sorry for this!)
Padman, thanks for your useful help in any time, and keep going!
