According that suggestion you do seem to have redo copy latch contention.
As far as getting that ratio close to suggested value, you may set some special
init.ora
parameters. There is plenty of notes on Metalink for that.
But, you should first determine if this is causing any performance issue. Have you
explored all
other avenues to address those issues. If not, I would not worry about this
contention.
