RE: Extent allocation for objects

Am I the only one who praises locally managed tablespaces with SYSTEM allocation?? Or am I the only one who is really tight on disk space? I started with UNIFORM allocation, thinking "I know better than to let Oracle handle it" and I realize now that system allocation saves me space.

Just my two cents

It's a characteristic of uniform size. If you have uniform size 512 M, then you can't have an extent that is any other size. So you can specify initial extent and next extent until you're blue in the face, but you will always get 512 M extent sizes. See? Maybe LMT is quite the grand panacea.
