                    to ORACLE-L

list,
this application heavyly make use of literals , NO BIND VARIABLES and was running without any lib cache latch or shared pool latch problems on
7.3.2

We ported the DB to 8.1.5 and v$session_wait is full of "latch free" event !!
all the latch waits are on lib cache and shapred pool (as expected from any app NOT using bind vars)
and the app is running terribly slow !!

my question is... how 7.3.2 was able to handle this ?? how i explain this to
my management ?
i was able to convince then on porting to 8i to get better perfornace !!

note: i cannot change the app. all changes must be from the back end.

TIA Rahul
