I personally am not a fan of auto extend. I like to have a procedure when adding new data files.
I tend to keep data files smaller against popular opinion, there is no performance loss with many different data files. Also there is less likely of having OS locks when data files are more and smaller. Also, it is much easier to manage them if they need to be moved around if they are only 100 or 500Mb rather than 10Gb or 100Gb.

I am setting up a new linux server (redhat 6.2 & oracle 8i 8.1.7) with a 1Ghz Processor and 512Mb RAM. How large should individual data files in a tablespace be allowed to grow? I can't find any advice on this in my oracle manuals/books. Is there a data file size that starts to hurt oracle. I've got one tablespace that will have 1-1.5 Gb of data. Should I allow a datafile to grow to that size, or would oracle like it better if I split it into 3 500Mb datafiles? Likewise, how should I handle the SYSTEM tablespace? Should I leave it as 1 large datafile or should it be broken into smaller ones?
I would also like to know what good oracle email lists are available to ask dba related questions other than this one.

Thanks,
