Hi!
Also, there is (or was?) a tradeoff between size
and number of datafiles.
Before 8i, ifI recall correctly, all datafile
headers had to be physicallyvisited (header SCN changes were written)
before a checkpoint could finish. If you got thousands of files, this adds
significant
Please correct me if I am wrong. With option 1, the datafile will dynamically extend, 1M at a time and there is no guarantee the datafile is contiguous on disk. That will increase your I/O time when Oracle need to find data all over the disk. And also with autoextend, you may run out of space on
prefer to add files.

My
first question is: Why are you adding a data file named "users" to your SYSTEM
tablespace? Do you mean to add this to your USERS
tablespace?
Next,
if you have an idea about the data growth or size of objects that you will place
in the new datafile then you can better
