Table sizing script

Hi,

Does any one has table sizing script. I have table with data. Now I need to find that, what should be the intial size, so that I can prepare a script for initial and next ext etc for the table creation script to go for production.

Initiallly the script was prepared with initial and next by guessing some thing.

I also need the same for index.

Thanks..

Populate the table with some sample data, analyze it and check AVG_ROW_LEN. Multiply this by estimated no. of rows.

Its not necessary to pack everything in one extent. Use uniformly sized extents if possible LMT.
