  All coboundary Lie bialgebras and their corresponding Poisson--Lie structures
are constructed for the oscillator algebra generated by $\{\aa,\ap,\am,\bb\}$.
Quantum oscillator algebras are derived from these bialgebras by using the
Lyakhovsky and Mudrov formalism and, for some cases, quantizations at both
algebra and group levels are obtained, including their universal $R$--matrices.
