SMP/E is a tool used to install and maintain software on z/OS systems. It controls changes at the element level, selecting proper levels of elements to install from potential changes and calling system utilities to install the changes. SMP/E manages this process through zones - a global zone contains software not yet installed, a target zone contains installed software, and a distribution zone contains backup copies of installed software. SMP/E uses functions, SYSMODs, elements and other packaging constructs to model software and changes.

2. Who is this session for?
• If you are new to maintaining software on the
mainframe and want to understand what
magic is happening under the covers of
• • Hear the buzzwords, get the scoop on the
lingo, see the structures, and learn the steps
to use SMP/E to keep your mainframe
humming.

3. What is SMP/E?
• SMP/E is the basic tool for installing and
maintaining software in z/OS systems and
subsystems. It controls these changes at the
element level by:
• Selecting the proper levels of elements to be
installed from a large number of potential
changes
• Calling system utility programs to install the
changes
• Keeping records of the installed changes

4. Why would you use it?
• • The product is delivered in this format
• • Upgrade a product
• • Fix a problem with a product
• • Track an installation defined change

5. Where does it fit in?
• The “mainframe” platform.
• MVS” environment aka OS/390, z/OS. Not VM.
Not Linux.
• Other Independent Software Vendors (ISV)
products.
• ISPF based dialog and Batch jobs.

6. An SMP/E environment - zones
• Global Zone
– Waiting to be installed
• Target Zone
– Runnable copy
• Distribution Zone
– Source
– Backup

7. SMP/E components -
Global Structure
• CSI - Consolidated Software Inventory
– Describes Target and Distributions zones
– Processing options
– Status of work in progress
– Exception data (hold for user acknowledgement)
• Libraries (DDDEFs)
– SMPPTS
– Logs

8. SMP/E components -
Target Structure
• CSI - Consolidated Software Inventory
– Describes executables
• Libraries (DDDEFs)
– Run-time (Product specific)
– SMP Temporary Store (SMPMTS, SMPSTS, …)
– Logs

9. SMP/E components -
Distribution Structure
• CSI - Consolidated Software Inventory
– Describes modules (programs and
subroutines)
• Libraries (DDDEFs)
– Samples
– Other text members
– Logs

10. SMP/E - packaging parts
• Function - A product identified by a unique FMID, a logical
group of elements.
– FMID - Function Modification IDentifier is a SYSMOD id
assigned to a function.
• SYSMOD id - Identifier assigned to a SYStem MODification.
– SYSMOD - input to SMP/E that defines the action to take on
one or more elements.
• Element - a single part of a product; a unique member of a
PDS(E) or file in an HFS.
• Program Temporary Fix (PTF) - a SYSMOD that changes one or
more elements.
• USERMOD - your modification to a vendor supplied element.

11. SMP/E - packaging parts
• Authorized Program Analysis Report (APAR) - a temporary fix
released before a PTF is packaged.
• Replacement Modification IDentifier (RMID) - used to identify a
SYSMOD that completely replaced an element.
• Updated Modification IDentifier (UMID) - used to identify a
SYSMOD that updated the last replacement of an element.
• COnditional REQuisite (COREQ) - identifies SYSMODs that can
only be installed correctly if both go on.
• PRE REQuisite (PREREQ) - identifies SYSMOD(s) that must have
been installed previously.
• Negative PRErequisite (NPRE) - mutually exclusive PREREQ.

12. SMP/E - processing terms
• Receive - makes known to the GLOBAL CSI.
– Similar to unzipping a pc based program and “cab” files that
are used to install a product.
• Apply - makes known to the TARGET CSI.
– Builds and copies the elements used to run the product.
• Accept - makes known to the DISTRIBUTION CSI.
– Copies elements to the backup libraries.
• Reject - tells the GLOBAL zone to forget about it.
• Restore - Rebuilds the Target version from what has been
accepted. Similar to ctrl-z or “undo”.

13. SMP/E - distribution
methods
• ServerPac - a complete set of products with applied
maintenance.
• CUM tape - cumulative service release between a span of time.
• Product tape - a product at its base level.
• CBPDO - a custom built product delivery option. This tape
contains one ore more products at their base level plus all
maintenance released.
• SUF - service upgrade facility is a java web based internet
application that can retrieve APARs and PTFs ensuring all
required maintenance is also received in your Global zone.
• ICSF - Internet Product/Maintenance Retrieval.
• FTP - service from Boulder.

14. Process Flow

17. Where do I begin?
• Backup
• Read the doc
• Receive the files
• Backup
• Read more doc
• Apply check

• Apply
• Backup
• Accept check
• Accept
• Backup

18. Backup
• Make sure you have a backup, outside of SMP/E
– Take a data set level backup of the global
datasets, the
target zone data sets, and the distribution zone data
sets.
– Coordinate with others who might be using these
data sets.
– Consider IPL volumes, HFS data sets, other run-
time datasets.

19. Read the doc
• Follow the directions as they apply to your
installation.
• Take note of any actions that need to be done.
• Coordinate with other areas.
• Develop your plan for testing and
implementing.

20. Receive the files
• GLOBAL processing.
– Use ZONEGROUP to exclude receiving items already
processed.

22. Research issues/ order more
service
• Review the “Causer SYSMOD Summary” report
and order/receive any missing
maintenance, identify actions to be
performed, and tailor your apply control cards
asnecessary.
•Check the File Allocation Report: know what
you are updating and make sure you have a
backup.
• Review other reports and take action as
necessary.

23. Apply
• Same JCL as your apply check.
• Remove “CHECK” from the control cards.
• Review all reports and make sure you know
what was updated.
– Did you notice the GLOBAL CSI is updated?
• Consider doing another backup.
• Test, Test, and test.

27. Did I really do that?
Did you do something you wish you hadn’t?
– You did have a backup, right?
– If you accepted something you need a non-
SMP/E restore.
– If you applied something, do you want SMP/E
to RESTORE it?
– Did you receive something you don’t want -
REJECT it.

29. Restore gotchas!
• You will regress back to the last accepted
levelset.
• You must select every applied but not
accepted sysmod.
• No guarantee an apply can get you back to
where you started from. New HOLDDATA may
prevent some sysmods from being applied in
your current environment.

30. Reject
• Used mostly to cleanup the SMPMTS.
• If you have room, don’t bother.
• May have to reject a sysmod to receive it
properly.
– Damaged during download and you did not
notice it.
– On usermods, consider updating the REWORK
value instead.

31. Namaskara!
• Thank you for not asking too many
questions!!!!!!!!!!! 
