Migrating to zOS R8 Part 1 - Messmer The Brain House

Migrating to z/OS R8 Part 1 of 3: Get Ready
� Recommended service includes all PTFs with a Recommended Service Update SOURCEID (RSUyynn) and
all PTFs that resolve HIPER problems or PTFs in error (critical service).
� All service includes all currently available PTFs.
� HOLDDATA: When you request HOLDDATA you get only the latest 2-years of Enhanced HOLDDATA for the
entire z/OS platform (see http://service.software.ibm.com/holdata/390holddata.html for further information on
Enhanced HOLDDATA).
Your PTF service order is customized to your SMP/E environment using a software inventory file that identifies your
installed FMIDs and the PTFs already present in your environment. This means you receive only the PTFs you
request that are applicable to your environment plus any requisites you don't already have on hand. Furthermore,
your order will not include any PTFs you already have, resulting in an order that is as complete and as small as
possible that can be downloaded and installed quickly.
The SMP/E RECEIVE command has been extended to support this Internet Service Retrieval capability. The
RECEIVE command will use the HTTP 1.0 protocol with SSL to communicate over the Internet with the dedicated
IBM server. The server accepts the PTF or HOLDDATA request from SMP/E and responds with the information
necessary to download the files of PTFs and HOLDDATA. SMP/E then uses the FTP protocol to download the files
from the IBM server to your local z/OS system.
� ICSF Mitigation: The z/OS Integrated Cryptographic Services Facility (ICSF) is used by SMP/E to calculate SHA-1
hash values. These hash values are calculated for files within a GIMZIP package to verify the integrity of the data
within the package.
SMP/E has been enhanced to use an alternate method to calculate SHA-1 hash values if ICSF is not available for
use. Although ICSF is the preferred method, SMP/E will no longer require it for use by the GIMZIP and GIMUNZIP
service routines, nor for the RECEIVE FROMNETWORK or RECEIVE FROMNTS commands. If SMP/E detects ICSF
is not available, then SMP/E will automatically use an SMP/E Java application class to calculate SHA-1 hash values
as an alternative.
� Improved Load Module Build: The load module build phase of the APPLY, RESTORE and LINK LMODS
commands is being enhanced to be more tolerant of allocation errors for the distribution libraries. This accommodates
distribution libraries which may be off-line. In this case, SMP/E continues its search for a useable copy of the module
instead of immediately failing because of the error allocating the distribution library.
SMP/E V3.4 was available on September 30, 2005. ServerPac orders are built using either the default level of SMP/E
(which is V3.4) or the lowest supported level of SMP/E that is required for the products in your order. The higher of these
two SMP/E levels is used. For example, z/OS orders are built with the level of z/OS SMP/E provided in that release of
z/OS. Subsystem orders are built with SMP/E V3.1, unless a product in your order has a dependency on a higher level of
SMP/E. Your subsystem order would then be built with the minimum level of SMP/E that satisfies the requirement. The
level of SMP/E used to build your order is documented in ServerPac Installing Your Order.
If it may be a while until you migrate to z/OS R8, you may want to consider ordering this separate product early (in a
CBPDO) in order to take advantage of the new functions in SMP/E right away!
If you would like to start using SMP/E V3 R4 to process electronic deliverables, then you may order it using ShopzSeries
(http://www.ibm.com/software/shopzseries) or download SMP/E V3 R3 from the download zone. The download zone can
be found at: http://www.ibm.com/software/os/ then Downloads (with parallel paths for both OS/390 and z/OS). SMP/E V3
R3 has been available via the download zone since October 1, 2004.
IBM Debug Tool for z/OS Version 6 Release 1 (5655-P14)
The latest available Debug Tool is the IBM Debug Tool for z/OS V6.1. IBM Debug Tool for z/OS is IBM's interactive
source-level debugging tool for compiled applications. It is a program testing and analysis aid that helps you examine,
monitor, and control the execution of application programs written in C, C++, COBOL, or PL/I on a z/OS or OS/390
system. By using the disassembly view, Debug Tool also provides support for programs compiled with the NOTEST
compiler option, or applications that include other languages.
Debug Tool for z/OS V6.1 includes the following new features and enhancements (among many):
� Breakpoints, monitors, and settings can now be saved and restored across debug sessions independent of the
environment in which Debug Tool is running.
� A set of prefix commands has been added so that you can interact with the Monitor window. The prefix commands
that are available in the Monitor window will generate the corresponding Debug Tool command line command. These
new prefix commands provide a better way to interact with the Monitor window.
� You can now set an AT ENTRY breakpoint without Debug Tool knowing about the program ahead of time. This
enhancement makes it easier to specify breakpoints.
