This paper considers effects of the general relativity and an accreting black hole in a globular cluster by studying the evolution of a globular cluster core as a whole (i.e., without the partition of the core into the so-called cusp and isothermal core regions). The globular cluster core is assumed to contain a massive black hole at its center. It is shown that the final fate of the evolution of a globular cluster core depends on the mass of the black hole at its center. When the mass M of the black hole is greater than 3000 solar masses, there will be a contraction of the core. On the other hand, if the mass of the black hole is smaller (between 100 and 3000 solar masses) in the center, the core will expand until complete dissolution.
