  We present a self-consistent local approach to self generated glassiness
which is based on the concept of the dynamical mean field theory to many body
systems. Using a replica approach to self generated glassiness, we map the
problem onto an effective local problem which can be solved exactly. Applying
the approach to the Brazovskii-model, relevant to a large class of systems with
frustrated micro-phase separation, we are able to solve the self-consistent
local theory without using additional approximations. We demonstrate that a
glassy state found earlier in this model is generic and does not arise from the
use of perturbative approximations. In addition we demonstrate that the glassy
state depends strongly on the strength of the frustrated phase separation in
that model.
