why would a query take 148 seconds to
parse? It is a two way union
where the first half is going against all_tables
and the second half is a join
between all_indexes and all_ind_columns.
The shared pool has 50M large parts of it are free. I generated a 10046 (level 12) trace, and I just don't see anything out of whack, except of the c=14868 in the PARSE #1 line.
