The full table scans on the hash joins and the outer join are killing you.

  1. Make sure the tables are analyzed. 2.. Make sure the where clause fields are indexed on the left side of the index.
  2. Break apart the query if needed using pl/sql nested loops or some other procedural language.
  3. Call functions in your sql to get results to break apart the the sql statement.
  4. Hints may help.
