Title: To create a new datafile or to increase a existing datafile.



In 
this case anything would do. Better would be to expand the already mentioned 
dfiles as the Sixth datafile would be placed on to some H.Disk and then I/O 
contention to that disk would increase. Better is to redistribute the load among 
the various datafiles. 

If you 
have one hard disk then it would not matter at all between the two different 
scenarios.

  Hello Gurus 
  Which is the better policy: Say you have five datafiles of 1GB in size each, now the 
  total freespace is less than 10%. Would it 
  be wise to increase the datafiles to 2GB or would it be better for the system 
  to add a sixth datafile? 
  Would appreciate any views on this point.

Denham,


You haven't mentioned tablespaces. If all five datafiles are for one tablespace, it doesn't matter much. However if each datafile is for a separate tablespace, it would be easier to increase the size of the existing datafiles. Otherwise you would need to move objects to take advantage of the sixth datafile.
