Support considerations in V2R1 - Support of Berkeley Internet Name Domain 9.2.0 (BIND 9.2.0) DNS server function is discontinued. If you used the z/OS BIND 9.2.0 function as a caching-only name server, use the z/OS resolver DNS caching function to cache DNS responses. If you used the z/OS BIND 9.2.0 function as a primary or secondary authoritative name server, investigate using BIND on Linux for System z® or BIND on an IBM® blade in a zBX.

IBM Configuration Assistant for z/OS Communications Server will no longer be offered as a stand-alone application that runs on the Windows operating system. IBM Configuration Assistant for z/OS Communications Server is available as a fully supported task in the z/OS Management Facility (z/OSMF) product.

When change was introduced: z/OS V2R1
