I am still confused by maxextents on a datafile and the more documentation and websites that I read the more confused that I get. If I have autoextend ON with NEXT set to 16384K then I understand that each time it has to extend it will extend in 16384K chunks. However, does maxsize value mean it will continue to allocate in those 16384K chunks until the total of those chunks reaches the size identified by maxsize? It doesn’t mean that maxextent is the total size the datafile can ever be (correct?) because I have some datafiles that are currently larger than their maxtent size... If you have NEXT set to 16384K, is there a recommendation of what size maxextents should be or is it just whatever you want to put it at? For example, does it need to be a multiple of block size or next extent, etc. When I use OEM and try and set Maximum Size to Unlimited and hit apply, it doesn’t show up with the Unlimited bullet highlighted. Instead it shows up as Value=32767MB. Why is that? Is 32GB the largest a datafile is ever supposed to be? This is 18.104.22.168 on RHEL5.
