dynamic views in 8.1.6

we have added these parameters in the init.ORA file . query_rewrite_enabled=true
_complex_view_merging=true
_push_join_predicate=true

optimizer_max_permutations=79000
_use_column_stats_for_function=true
_like_with_bind_as_equality=true
_push_join_union_view=true
_ordered_nested_loop=true
_or_expand_nvl_predicate=true

after these changes all the dynamic views created by developers have stopped working .

our database is running on aix 4.3.3 and its in MTS mode .

Will appreciate quick response.

thanks in advance .
