list,
i just ported a system to 8.1.5, the application DOES NOT make use
of bind variables, each and every query (fired from 8 clients every 2-3
seconds)
parses and executes, this keeps the shared pool patch also very busy...
i cannot tune the app, is there something i can do to reduce the lib cache
and shared pool
latch contention ??
v$session_wait show all sessions waiting on "latch free"
the sleeps in lib cache latch are not properly spread out also...
SQL> select * from v$latch_children where latch#=99 order by 8
CHILD# GETS MISSES SLEEPS

Interestingly, the same app was NOT showing any contention on these latches
in 7.3.2 !!
how can i solve this problem ?
TIA
