But!...
Please remember that "getting rid of table scans" is not necessarily a smart goal. Oracle only provides a few ways to join tables:
Each is suitable in its place. If you eliminate all full-table scans, then the only one of these that you have left is nested loops. In certain circumstances, a nested loops execution plan can motivate run times of hundreds of hours.

Check Appendix C of the Reference Manual. Look at 'table scans'.

cc: Subject: statpack & v$sysstat - stat# 140
Hi List,
While reading statpack book, came across a script which is using stats$sysstat to estimate FTS. The statistic# used is 140 which is 'transaction lock foreground requests' (Ver.8.1.7.4)
The value for this statistic# in v$sysstat is zero. Is there a way to
find
out FTS from v$sysstat ? If yes, what is the statistic# name ?
Thanks,
~Dilip
