Manavendra:
- No, the database does not have to be offline. Oracle will resize
"on-the-fly"
- The only way to extend the tablespace prior to oracle 8 was to add
datafiles; and yes, I think it's easier to simply add datafiles.
- Not sure if this is true, but I believe an old DBA friend of mine
suggested that oracle was not very efficient when extending datafiles. That
much of the space you allocate to extend the datafile is actually lost to
overhead. Could somebody please clarify if this is true? It would seem to
me that optimal database performace requires you to add datafiles to the
tablespace when required...

1. wouldn't you need to bring the database offline to resize the datafile?
2. will it not be easier to just add another datafile?
3. what is the recommended choice?
With Warm Regards,
Manav.
