Buffer busy waits ratio=(buffer busy waits)/(consistent gets + db block
gets)
If this ration is greater than 5% there is a problem. As usual, this problem
indicates
a wait for a rollback segment buffer. You should add more rollback segments
until
"undo header waits" is 0 in V$WAITSTAT. Also this problem can point to low
value of
"free lists" option (if you have multiple processors).
