Remove as many compiled statements (plans) as possible from the database-wide statement cache.
The SYSCS_UTIL.EMPTY_STATEMENT_CACHE stored procedure removes as many compiled statements (plans) as possible from the database-wide statement cache. The procedure does not remove statements related to currently executing queries or to activations that are about to be garbage collected, so the cache is not guaranteed to be completely empty after a call to this procedure.
CallableStatement cs = conn.prepareCall ("CALL SYSCS_UTIL.EMPTY_STATEMENT_CACHE()"); cs.execute(); cs.close();
