1. VSAM increases the disk space requirements. For self-
reorganization free space must be deliberately left.
2.Except for read-only the integrity of VSAM datasets in
cross region/system must be maintained by the user.

Answer / nihar ranjan karan
The biggest disadvantage of a VSAM dataset I believe is
that it can be only be created on a DASD. So it obviously
means you cannot use any other media for storage and
retrieval of VSAM datasets.

DISADVANTAGES:
(i)the vsam file have FREE SPACE parameter with in the CI.
so,it will take large memory space.
(ii)it have CONTROL INFORMATION by itself. that's why it
will take more memory space.
