I was unaware that cursor_sharing can take a value of "false". I thought that
cursor_sharing can take values of "exact", "similar" and "farce". The problem
with setting to "farce" was that there were many bugs, so it was deemed dangerous,
but I haven't had any problems with it on 10.2. It's a great thing FOR AN OLTP
CONFIGURATION.

As for stored outlines, the document correctly states that they cannot cope
with anything that changes SQL. Setting cursor_sharing to "farce" causes
constants in the SQL statements to be internally replaced with bind variables.
Yes, outlines do not work very well with query_rewrite_enabled or cursor_sharing
set to "farce".
