comment solvability condition for differential operator
@TZakrevskiy, from your comment now I understand what is meaning of self-adjoint differential operator. Honestly I could not understand answer given by you at all because my ineptness in this field. Anyway thanks for your answer and explanation..!

comment finding a parameter to match the solution asymptotically
@JuliánAguirre, If I solve the equation with boundary conditions $y'(-3) =0$ and $y'(3) = 1$ in Mathematica, fine tuning of parameter $b$ shows that, I can make $y(-3)$ as small as possible. But if I start with boundary conditions $y'(-3) =0$ and $y(-3) = 0$, Mathematica declares problem as ill conditioned.

@JuliánAguirre, that x axis is an asymptote to y(x) as x tend to -3.
