• SMP/How?
– The System Modification Program Internals
– Exploring an existing product
– The installation process
– Undoing a fix
– Creating a software package

Disclaimer
• This is going to be a deeply
technical, nerdy
presentation

Speaker Introduction
• Michael Erichsen has about 35
years of experience of systems
programming, architecture, and
a bit more…
• Built the SMP/E packaging for a
commercial product recently
• Is part of the Xact Enterprise
Modernization team, which
specializes in supporting
customers with IBM products like
– ZD&T
– IBM Developer for z and i
– Rational Team Concert

SMP/Who?
• SMP/E Roles
– Installers
– Auditors
– Packagers
• Intended session audience
– Systems programmers
• Perhaps want know a little more about
one of their main tools
– Developers
• DevOps is among other about
understanding each other
• This is partly phrasebook for
understanding Sysprogs
– Auditors
• Which version of the program updated
my data?

SMP/What?
• Requirements for a System
Modification Program
– Consistent and robust installation
– Versioning
– Maintain by adding and removing
fixes
– Self-documenting
– Adaptable to your other software
– Common for IBM and 3rd party
vendors
– Tolerant of syntax variations
• Not configuration
– But possibly protecting your
configurations
• Not for application software

SMP/When?
• It has been around for a long time
• OSMP (OS Maintenance Program) first introduced for OS/360
– Possibly around 1966
• Evolved into SMP (System Modification Program)
• SMP/E (SMP Extensions)
– Introduced with MVS
• Very stable, robust and flexible product
• Documentation seems to expect you to have been around as long
as SMP/E…

SMP/How?
System Modification Program Internals

SMP/How? System Modification Program Internals
• CSI
– Consolidated Software
Inventory
• Relfiles
– Packaging for transportation
• Target libraries
– Runnable system
• Distribution libraries
– Backup mechanism
• FMID’s
– Function Modification Identifier
• DDDEF’s
– DD card definitions
• OPTIONS
– PURGE will remove ACCEPTed
PTFs from the PTF Temporary
Store data set
• Why target, but no source
libraries?

Prepare the SMP/E Environment
• Create the CSI and other SMP/E datasets
• Before installation you tell SMP/E about your existing system
– SMP/E uses DDDEF’s (DD card DEFinitions) to include your current
versions of z/OS, DB2, CICS etc. load libraries
– If your DDDEF points DSNLOAD to DSNC10.SDSNLOAD
• Then any data set name using DSNLOAD as DD card will be replaced by
DSNC10.SDSNLOAD

Identify existing Versions of other Software
Product High-Level Qualifier
CICS DFH550.CICS
COBOL IGY620
DB2 DSNC10

The Physical Structure
Xact Consulting A/S Arnold Nielsens Boulevard 68A 2650 Hvidovre, Denmark E-mail: info@xact.dk Telefon: +45 70 23 01 00 15
• The actual runtime
elements are stored in
PDS’es, sequential datasets
and zFS files
• PTF’s and other elements
are stored in a set of PDS’es
until ACCEPTed
• All definitions of a product
is stored in a VSAM data set
called a CSI (Consolidated
Software Inventory)
• FEK140.GLOBAL.SMPLOG
• FEK140.GLOBAL.SMPLOGA
• FEK140.GLOBAL.SMPLTS
• FEK140.GLOBAL.SMPMTS
• FEK140.GLOBAL.SMPPTS
• FEK140.GLOBAL.SMPSCDS
• FEK140.GLOBAL.SMPSTS

The Consolidated Software Index
• A single VSAM data set with
logical subdivisions (zones)
– FEK140.GLOBAL.CSI
– FEK140.GLOBAL.CSI.DATA
– FEK140.GLOBAL.CSI.INDEX
• A set of linked VSAM data
sets
– E. g. one for each zone
– MVS.GLOBAL.CSI
– MVS.GLOBAL.CSI.DATA
– MVS.GLOBAL.CSI.INDEX
– MVS.MVSD.CSI
– MVS.MVSD.CSI.DATA
– MVS.MVSD.CSI.INDEX
– MVS.MVST.CSI
– MVS.MVST.CSI.DATA

Installation Package Contents
• Program Directory
• Readme.txt
• SMPMCS
• RELFILES
– F1 normally contains “JCLIN”
• Mostly link-edit jobsteps
– F2 is normally installation jobs
• JCL for RECEIVE, APPLY, ACCEPT and other tasks
– The rest are object modules, samples, procedures, Java jar files etc.

The Standard SMP/E Job Stream
38

First define an ALIAS for the new Data Sets
39

Receive
• Store the package under SMP/E control
• Copy RELFILES into a new set of RELFILES
• HOLDDATA
– IN ERROR
– ACTION
– DOCUMENTATION
– Pre- and corequisites

SMP/E FMID LIST after Receive
44

SMP/E Cross Zone Query after Receive
45

Product Libraries
• Target libraries
– “S” + three letter acronym + type
– Have a guess of what they are!
• Distribution libraries
– “A” + three letter acronym + type
• zFS libraries
47

Make zFS Directory Structure Output
49

SMP/E Target Zone DDDEF’s after DDDEF
52

Apply
• Install the package as a runnable system under SMP/E control
• Copy or link edit into target libraries

SMP/E Cross Zone Query after Apply
59

Configure
• Copy to test libraries
• Configure PROCLIB, PARMLIB, Supervisor Calls, authorized
libraries, etc.
• Done outside SMP/E control
– But a configuration can be protected from being overwritten by
SMP/E using a USERMOD

Deploy
• Copy to test and production
LPAR’s

Accept
• Create an advanced type of
backup under SMP/E
control

SMP/How? Undoing a Fix

Restore
• Undo a fix under SMP/E
control
• Copying sources back into
target libraries
• Relinking load modules in
the target libraries using
objects in the distribution
libraries

Reject
• Remove a fix from SMP/E
control
• Delete from system

Remove Everything
• The only way to get rid of
something after ACCEPT is
to remove everything
• Delete the CSI and all other
datasets and start over

Program Directory
• Very identical between all products
• Describes prerequisites
• Describes the standard RECEIVE/APPLY/ACCEPT/Etc. jobs
• Describes post-installation tasks
– Normally just a reference to a Customization Guide

Readme
• Package upload instructions
• Define an installation zFS file system (Optional)
• Unpax
– This step expands the single download file into the individual archive files
that make up the download package
• GIMUNZIP
– This step extracts the FMID(s) and related materials from the download
package archive files and places them in RELFILE and SMPMCS
• Copy installation jobs
– This step allocates an installation PDS and copies the installation jobs there

ABCWEDIT Edit macro to help edit the jobs
ABCALIAS Define Alias
ABCSMPSU Create CSI and SMP/E datasets
ABCRECVE Receive not global zone
ABCALLOC Allocate target and distribution data sets
ABCDFZFS Define zFS data sets
ABCMKDIR Create directory structure in zFS
ABCDDDEF Define DDDEF’s
ABCAPPLY Apply into target zone
ABCACCEPT Accept into distribution zone

Packaging Jobs
• ALLOCREL
– Allocate README and SMPMCS data sets and RELFILES
• EXTRCICS (Optional)
– Run CICS CSD utility program to EXTRACT OBJECTS
– Run IEBGENER GENERATE to a member in e. g. XABCINST

Packaging Jobs
• POPLTREL
– Populate README and
SMPMCS data sets and
RELFILES
– IEBCOPY COPY object
modules, which must have
been linked NCAL and as
single object load modules
– IEBGENER GENERATE source
elements and zFS elements

Conditional Requisites (IFREQ)
• PD Tools Common Component, the HVWR170 function, has
been installed nicely by itself
• But IBM has found out that if you also install some other
product you will need some PTF’s to HVWR170 to make them
work together
• Let us have a look at the SMPMCS for HADRE00
