We present a detailed analysis of the domain walls in supersymmetric gluodynamics and SQCD. We use the (corrected) Veneziano-Yankielowicz effective Lagrangians to explicitly obtain the wall profiles and check recent results of Dvali and Shifman: (i) the BPS-saturated nature of the walls and (ii) the {ital exact} expressions for the wall energy density which depend only on global features of dynamics (the existence of a nontrivial central extension of N=1 superalgebra in the theories which admit wall-like solutions). If supersymmetry is softly broken by the gluino mass, the degeneracy of the distinct vacua is gone, and one can consider the decay rate of the {open_quotes}false{close_quotes} vacuum into the genuine one. We do this calculation in the limit of the small gluino mass. Finally, we comment on the controversy regarding the existence of N distinct chirally asymmetric vacua in SU(N) SUSY gluodynamics. {copyright} {ital 1997} {ital The American Physical Society}
