Re: shared server implementation in Oracle 11G R2

With shared server PGA comes from SGA. That means that PGA_AGGREGATE_TARGET is not used, among other things. With the automatic shared memory management (ASMM), you don't need to allocate shared pool, but you do need to allocate significantly larger SGA. BTW, that is the case even with multithreaded implementation of 12c.
