MTS versus dedicated for resolving a ORA-04031.

We have upgraded our databases from 8174 to 9203.  

We have started encountering ORA-04031's on processes that are using MTS.  Once 
we switch that process to use a dedicated connection then the problem goes 
away.  This problem did not occur when we were using 8174.

For 8174, the shared pool was 100M.  Large pool = 0. reserved is 10%.
For 9203, the shared pool was doubled to 200M.  Large pool = 0.  reserved is 
10%.

Any thoughts??  Are we killing ourselves by doubling the shared pool??  Does 
everyone else set their large pool to zero???

TIA.
