Home -> Community -> Usenet -> c.d.o.server -> Re: Resizing Datafile
Hi,
some of used blocks lie behind yor specified size. So you know, that you have a fragmented tablespace (that is normaly if you have a mix of insert, update and delete operations) with free blocks in the middle or in front of but not exclusiv at the end of your datafile. current_size minus free_size is to small, because you datafile has no sequential organisation and the resize oeration will shrink a datafile at the end!
Bye, Jan
