Migrating to zOS R8 Part 1 - Messmer The Brain House

Migrating to z/OS R8 Part 1 of 3: Get Ready
Elements and Functions Withdrawn from z/OS R6
C/C++ ISPF panels (from
C/C++)
Run-time Library Services
(RTLS) (from Lang Env)
Dynamic Link Library (DLL)
Rename Utility (from Lang
Env)
SMIv1 version of the IBM MVS
Enterprise-specific MIB
module (from
Communications Server)
Priced Feature - invoke the C/C++ compiler
via UNIX, JCL, or TSO/E.
Base Element - no longer required due to
stability and upward compatibliity
Base Element - no longer needed due to
C/C++ DLLs being licensed with the z/OS
base
Base Element - if you want to continue to use
SMIv1, publicly available available tools can
convert SMIv2 to SMIv1
DCE Application Support Base Element - no replacement necessary.
Evaluate WebSphere for similar function
Encina Toolkit Executive Base Element - no replacement offered.
Marketplace has moved to other technologies
Text Search Base Element - available via web deliverable if
still necessary for certain usage

Withdrawn in z/OS V1.6 (last delivered in z/OS V1.5)
This section lists items that were withdrawn in z/OS R6. You should take this into account as you plan your migration to
z/OS R8. The removal of these functions may have migration actions which you can perform now, in preparation for z/OS
R8.
� The C/C++ ISPF panels, which include panels for C/C++ foreground compiles, C/C++ background compiles, and help
panels for these compiles, are removed in z/OS V1.6. The z/OS C/C++ compiler can be invoked through z/OS UNIX,
using JCL, and under TSO/E.
� z/OS base element Language Environment's use of run-time library services (RTLS) is withdrawn in z/OS V1.6. This
function is used primarily in run-time migration. Given the stability and the upward compatibility being provided by the
Language Environment run-time library in recent releases of OS/390 and z/OS, this functionality is no longer required.
� The Dynamic Link Library (DLL) Rename Utility, part of z/OS Language Environment, is removed in z/OS V1.6. This
utility is used to package and redistribute IBM-supplied DLLs with applications. Since OS/390 V1R3, the C/C++ DLLs
have been licensed with the OS/390 and z/OS base operating system. Therefore, the DLL Rename Utility is no longer
required.
� z/OS Communications Server support for the SMIv1 version of the SNMP IBM MVS TCP/IP Enterprise-specific MIB
module is eliminated in z/OS V1.6. Support will continue for the SMIv2 version of this MIB module. For customers who
want to continue using SMIv1, publically available tools can be used to convert an SMIv2 MIB module to an SMIv1
MIB module.
� Effective with z/OS V1.6, IBM has removed the base element, Distributed Computing Environment (DCE) Application
Support, from z/OS. DCE Application Support facilitated the interaction between DCE clients and CICS or IMS
regions. With the continued evolution of technology and accompanying changes in the marketplace, there is no need
for this support. If similar function is required, IBM recommends that customers use IBM WebSphere. The DCE Base
Services element, which provides services for developing and running client/server applications, is planned to
continue to ship with z/OS and z/OS.e.
� Effective with z/OS V1.6, IBM has removed the base element, Encina Toolkit Executive from z/OS. Encina Toolkit
Executive provided a set of tools for developing client components of distributed transactional applications. Over time,
