Carlos,

This doesn't seem to agree with a blog post that Randolf Geist wrote some time ago: http://oracle-randolf.blogspot.co.uk/2011/01/adaptive-cursor-sharing.html

He does mention a bug, relating to ACS not working properly with PL/SQL, and presumably that's fixed by now; even so, "checking before every EXECUTION" doesn't seem to match his observations.

Regards
Jonathan Lewis
