Design tablespaces with more files of smaller size (2Gb is a nice size). Use this rule unless the number of datafiles in the database will get unmanageable. You describe a 15Gb database that will grow to 25Gb in a year -- this is not a large database, stick with 2Gb or smaller datafiles.

The advantage of smaller datafiles comes with backup/recovery. In the event that a single datafile needs recovery, a smaller datafile can be recovered more quickly than a larger datafile.

If you take RAC out of Oracle you get OLE! What can this mean?

Hi DBA gurus,

One of the application is going live .At presenr data is 15GB and will grow more by 10 GB in year time. What is the right approach of tablespace design having more files of smaller size(10 files of 2 GB ) or less file of bigger size (3 files of 8 gb ). No tables in this application is partitioned all the files will be on a single disk I am Orcale 8.1.7 on Win 2K.

2) Following is output of my v$waitstat . Kinly give som suggestions

CLASS                   COUNT       TIME
