Well it means what it says. Just read it a couple more times.
Just set it ON and leave it ON.
Data file 1 is the SYSTEM tablespace. In other words whenever you are doing a backup that includes the SYSTEM tablespace you also get a backup of the control file and the spfile ( if you are using an spfile ).
The purpose of having it in a different backupset versus the same one is for the most part not a big thing to worry about.
For normal sized databases ... backup the whole database at the same time please. Received on Fri Aug 29 2008 - 15:47:24 CDT
