Among the long list of features I have extracted these three.
I think I understand shared and multiplexed log files (and how
that is basically the same thing.) What I don't understand
is the multiple log files.
Are you saying that Oracle (v7 ?) allows you to configure
multiple REDO log files (for the same database) all of which
can be used simultaneously? I am aware of how multiple files
can be configured into a single logical file and how they are
used serially, but that's not what I would call multiple log
files since only one file is active at any time.
