Are you going with 2048M or the traditional 2000m? A quick & dirty way to not waste the space is to use 2001m or 2041m. You 'waste' a little space, but not much.

Okay, I'm about to create some locally managed tablespaces for some large partitioned tables. I plan on making each datafile 2GB, with an extent of 20M.

What I've done other times when I use LMTs is add 64K to the file size, for the bitmap header, so that I don't waste most of an extent. But in those cases, the datafile size has been less than 2GB.

We will be on Solaris 2.8, I know that the OS can handle files larger than 2GB but it makes me nervous to do this.

I hate to waste most of 20M just for the bitmap header.

Is my thinking way off? If you've been doing this sort of sizing (it's a data warehouse, yes), what have you done?

thanks!
