way to make sql statement stay on cache (SGA) logner?

We have ORACLE 10GR2 on UNIX server and some of SQL statements run much longer 
on first after that it only run few seconds.  I know the reason first time SQL 
statements run need parse and other things, after that SQL statement on cache 
(SGA) and it will run shorter.  But eventually SQL statement still will be age 
out from SGA.

Does there has way to make SQL statement stay longer on cache (SGA)?

Thanks.
