I had to do the following to get function based indexes working.
But I have Oracle 9i. You can check 10g documentation to confirm.
You must have the following initialization parameters defined to create
a
function-based index:
QUERY_REWRITE_INTEGRITY must be set to TRUSTED
QUERY_REWRITE_ENABLED must be set to TRUE
COMPATIBLE must set to 8.1.0.0.0 or a greater value
