RE: METALINK and OWS

Joe/Sean:

You don't need OPS to see this. Basically, alter system affects an instance (e.g. SGA stuff) whereas alter database affects the database (e.g. datafiles, controlfile). But some commands *are* confusing, e.g. ALTER SYSTEM SWITCH LOGFILE or CHECKPOINT vs. ALTER DATABASE ADD LOGFILE or RECOVER. With OPS it's a little easier to understand when you have separate instances with one database. Then again, remembering syntax is just what you need for that OCP moniker.... ;-)
