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.

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

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

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.

An SMP/E environment - zones

• Global Zone– Waiting to be installed• Target Zone– Runnable copy• Distribution Zone– Source– Backup

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

SMP/E components -Target Structure

• CSI - Consolidated Software Inventory– Describes executables• Libraries (DDDEFs)– Run-time (Product specific)– SMP Temporary Store (SMPMTS, SMPSTS, …)– Logs

SMP/E components -Distribution Structure

• CSI - Consolidated Software Inventory– Describes modules (programs and

subroutines)• Libraries (DDDEFs)– Samples– Other text members– Logs

SMP/E - packaging parts

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

SMP/E - packaging parts

• Authorized Program Analysis Report (APAR) - a temporary fixreleased before a PTF is packaged.• Replacement Modification IDentifier (RMID) - used to identify aSYSMOD that completely replaced an element.• Updated Modification IDentifier (UMID) - used to identify aSYSMOD that updated the last replacement of an element.• COnditional REQuisite (COREQ) - identifies SYSMODs that canonly be installed correctly if both go on.• PRE REQuisite (PREREQ) - identifies SYSMOD(s) that must havebeen installed previously.• Negative PRErequisite (NPRE) - mutually exclusive PREREQ.

SMP/E - processing terms

• Receive - makes known to the GLOBAL CSI.– Similar to unzipping a pc based program and “cab” files thatare 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 beenaccepted. Similar to ctrl-z or “undo”.

SMP/E - distributionmethods

• ServerPac - a complete set of products with appliedmaintenance.• 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 tapecontains one ore more products at their base level plus allmaintenance released.• SUF - service upgrade facility is a java web based internetapplication that can retrieve APARs and PTFs ensuring allrequired maintenance is also received in your Global zone.• ICSF - Internet Product/Maintenance Retrieval.• FTP - service from Boulder.

Process Flow

• Build environment• Receive• Apply• Test• Accept• Other backup

Where’s your backup?

• Physical volume(s)• Logical data set• SMP/E distribution libraries• SMP/E Zone(s)– Global– Target– Distribution

What do I order?

• ServerPac– System replacement• CBPDO– Product upgrade• Service– PTF and/or APAR

Backup

• Make sure you have a backup, outside of SMP/E– Take a data set level backup of the global

datasets, thetarget 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.

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.

Receive the files

Research issues/ order moreservice

• 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.

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.

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.

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.

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.

Namaskara!
