Hi,
I checked on "test DB". In my control file MAXDATAFILES is 300. I set
db_files=600 in pfile . And bounced the DB. It came up properly. After
that i took backup of control file to trace in that file MAXDATAFILES is
still 300. and if you check
show parameter db_files its showing 600.
So i am confused . Will it give me error when i am trying to add file no
301. Coz control file holds value 300 and pfile contains 600.

Can any body explain.

Rgds
